Review and introduction of different parts of control valves

Image
 Control valves are one of the applications in home and industrial applications. We have talked about it in previous articles. In this article, in addition to an overview of its use, we want to introduce Control Valve Parts . Stay with us. What is Control Valve? A control valve is a valve used to control fluid flow by varying the size of the flow passage as directed by a signal from a controller.This enables the direct control of flow rate and the consequential control of process quantities such as pressure, temperature, and liquid level. In automatic control terminology, a control valve is termed a "final control element". Bad fuel can cause key engine parts, such as the injection control unit, fuel pressure control valve, fuel oil pump or cylinder liners and piston rings to go from new to unusable in no time.  Read more The main purposes of control valves: Relieving the system from specific pressures Controlling the flow direction Increasing or decrease the flow Parts of co

The difference between a globe valve and a ball valve

Image
 In this article, we are going to examine the differences between globe valve and ball valve . We will first introduce each one separately. Then we examine their differences. If you want to know these differences, read this article to the end. Globe Valve A globe valve, different from ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. High-head-loss valves, such as globe valves, are commonly used for control purposes. Significant losses occur with these types of valves, however, even when they are fully open. If the evaluation shows that a control valve is needed, choose the type that minimizes pressure drop across the valve. Read more Ball Valve A ball valve is a form of quarter-turn valve which uses a hollow, perforated and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degre

Industrial valves and its applications

Image
 Industrial valves are not only used in industry but also in residential and commercial buildings. The main task of industrial valves is flow control. This article is an overview of industrial valves and their types and applications. Join us and read this article. A valve is a device or natural object that regulates, directs or controls the flow of a fluid (gases, liquids, fluidized solids, or slurries) by opening, closing, or partially obstructing various passageways. Valves are technically fittings, but are usually discussed as a separate category. In an open valve, fluid flows in a direction from higher pressure to lower pressure. The word is derived from the Latin valva, the moving part of a door, in turn from volvere, to turn, roll. Click here Valves are mechanical devices that control the flow and pressure within a system or process. They are essential components of a piping system that conveys liquids, gases, vapors, slurries, etc. Outside the home, industrial valves are built

What is Flow control valve?

Image
You must have seen the flow control valves at home by now and you are somewhat familiar with it. Its main task is to control the flow of fluid. In this article, we will fully introduce the flow control valves. In fact, you will get acquainted with Flow control valve types and functions. Stay with us. A flow control valve regulates the flow or pressure of a fluid. Control valves normally respond to signals generated by independent devices such as flow meters or temperature gauges. Control valves are normally fitted with actuators and positioners. Pneumatically-actuated globe valves and diaphragm valves are widely used for control purposes in many industries, although quarter-turn types such as (modified) ball and butterfly valves are also used. Typically, for a closed pressure control loop, the pressure in an enclosed volume is controlled. The pressure within the closed volume is measured and used as feedback for the closed control loop. Then the controller sets the position of the flo

Surely you have heard the name of electric motors many times and you have information about it. In this article, we intend to define and study electric motors in more detail. We will also introduce the different types of electric motors and explain each one separately. Stay with us. An electric motor is an electrical machine that converts electrical energy into mechanical energy. Most electric motors operate through the interaction between the motor's magnetic field and electric current in a wire winding to generate force in the form of torque applied on the motor's shaft. Electric motors can be powered by direct current (DC) sources, such as from batteries, motor vehicles or rectifiers, or by alternating current (AC) sources, such as a power grid, inverters or electrical generators. An electric generator is mechanically identical to an electric motor, but operates with a reversed flow of power, converting mechanical energy into electrical energy. Using frequency converters me

Is solar energy renewable?

Image
 In the previous articles, we introduced solar energy. In this article, we intend to review the previous articles to examine the issue of whether solar energy is renewable or non-renewable ? To answer this question, read this article to the end.

 HVAC stands for Heating, Ventilation, and Air Conditioning and is a device that provides heat and cold and generally heat and ventilation of an environment, whether it is a building or a car. First, we will explain the full definition of Wikipedia from HVAC, then we will mention and review the types of HVAC, and at the end, we will name and explain its components. So read this article to the end and stay with us. What is HVAC ? Heating, ventilation, and air conditioning (HVAC) is the technology of indoor and vehicular environmental comfort. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation, as HVAC&R or HVACR or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part

All the positive points of Tidal Energy

Image
 The conversion of tidal energy into electrical energy (and other energies) is called tidal energy. Tidal energy is very expensive while renewable and does not harm the environment. In this article, we intend to express the positive points of tidal energy and have an overview of this energy. So read this article to the end. Tidal power or tidal energy is harnessed by converting energy from tides into useful forms of power, mainly electricity using various methods. Although not yet widely used, tidal energy has the potential for future electricity generation. Tides are more predictable than the wind and the sun. Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities, thus constricting its total availability. However, many recent technological developments and improvements, both in design (e.g. dynamic tidal power, tidal lagoons) and turbine technology (

How many types of ball valves do we have and what parts are they made of?

Image
Ball valves are a type of valves that are used in industrial and domestic applications. But they also have different types. Join us to learn about different types of ball valves and their efficiency. A ball valve is a form of quarter-turn valve which uses a hollow, perforated, and pivoting ball to control flow through it. It is open when the ball's hole is in line with the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies flat in alignment with the flow when open, and is perpendicular to it when closed, making for easy visual confirmation of the valve's status. The shut position 1/4 turn could be in either CW or CCW direction. (S = SHUT, O = OPEN) Ball valves are durable, performing well after many cycles, and reliable, closing securely even after long periods of disuse. These qualities make them an excellent choice for shutoff and control applications, where they are often preferred to gates and globe valves, but they lack their fine control i

 Wind energy is a type of energy in which fossil fuels play no role and do no harm to the environment. But this type of energy, like other energies, has many disadvantages in addition to many advantages. Join us in this article to explore the advantages and disadvantages of wind energy . Wind power or wind energy ind power or wind energy is the use of wind to provide mechanical power through wind turbines to turn electric generators for electrical power. Wind power is a popular sustainable, renewable source of power that has a much smaller impact on the environment compared to burning fossil fuels. Wind farms consist of many individual wind turbines, which are connected to the electric power transmission network. Onshore wind is an inexpensive source of electric power, competitive with or in many places cheaper than coal or gas plants. Onshore wind farms have a greater visual impact on the landscape than other power stations, as they need to be spread over more land and need to be buil

Guide to the Air Compressors

Image
 An air compressor is a device that converts force into energy stored in compressed air. This device is widely used in home and industrial applications. To buy an air compressor, you need a complete guide about this device. It is also better to be familiar with the types of air compressors . So we suggest you read this article to the end. An air compressor is a pneumatic device that converts power (using an electric motor, diesel or gasoline engine, etc.) into potential energy stored in pressurized air (i.e., compressed air). By one of several methods, an air compressor forces more and more air into a storage tank, increasing the pressure. When the tank's pressure reaches its engineered upper limit, the air compressor shuts off. The compressed air, then, is held in the tank until called into use.[1] The energy contained in the compressed air can be used for a variety of applications, utilizing the kinetic energy of the air as it is released and the tank depressurizes. When tank pre

All you need to know about Globe valve

Image
 Globe valves are used to regulate the flow of gas and liquids. In this post, in addition to the introduction, we will review the different parts of globe valves . Thank you for your support. A globe valve, different from a ball valve, is a type of valve used for regulating flow in a pipeline, consisting of a movable plug or disc element and a stationary ring seat in a generally spherical body. Globe valves are named for their spherical body shape with the two halves of the body being separated by an internal baffle. This has an opening that forms a seat onto which a movable plug can be screwed in to close (or shut) the valve. The plug is also called a disc or disk. In globe valves, the plug is connected to a stem which is operated by screw action using a handwheel in manual valves. Typically, automated globe valves use smooth stems rather than threaded and are opened and closed by an actuator assembly. The Globe valve is a low profile yet durable design that utilizes a frangible glass

Circuit Breaker and its types

Image
 What is a Circuit breaker? In a nutshell, a circuit breaker is an electrical switch that is used to protect an electrical circuit from damage caused by a short circuit. Join us for a comprehensive overview of circuit breakers. We will also introduce the types of circuit breakers and their applications. A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household appliance, up to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an auto

Everythings about Head of a Pump

Image
What is Head of a Pump? The pump head or discharge head of a water pump is a measure of the power of a pump. The greater the pump head, the greater the pressure that the pump can generate. This statistic is measured in meters (or feet) and is calculated by placing a tube on a pump’s discharge and measuring the maximum height to which it can pump water. This was a brief definition of the pump head. In the continuation of the article, we will carefully examine the pump head and compare it with other components, so stay tuned and read this article to the end. A positive-displacement pump makes a fluid move by trapping a fixed amount and forcing (displacing) that trapped volume into the discharge pipe. Some positive-displacement pumps use an expanding cavity on the suction side and a decreasing cavity on the discharge side. Liquid flows into the pump as the cavity on the suction side expands and the liquid flows out of the discharge as the cavity collapses. The volume is constant through
