What is the flow control valve?

The flow control valve is a mechanical device used to control and control the flow of liquid or gas. Typically, these control valves are non -technical, they usually rely on undesirable conditions of regulated substances to open or close the valve. Occasionally, the flow control valves will be regulated by external monitoring devices such as pressure and temperature measures. In certain applications, the flow control valve is usually used either by either a membrane or a globe valve, although different valves are used in certain applications - as with modified ball and gate valves. This type of flow control valve is known as the automatic control valve because it does not require any external mechanism or sensor to help regulate the opening of the valve. Instead, these valves use the built -in relief mechanism. These relief mechanisms come in a wide range and use uniform conditions of regulated fluid for operation.

One example is known as a relief valve. FromWe are as control valves of pressure flow, relief valves usually occur on wigs generators and are used to prevent explosion of steam. If the steam did not regulate, it could extend to the point where the boiler tube would tear. In the relief valve itself, the only output for steam leakage is held under a certain amount of resistance. The force required to overcome the resistance of the relief valve is equal to the maximum pressure capacity of the boiler; This means that once the steam reaches too high pressure, the steam pressure itself will be sufficient to open the valve.

Another type of flow control valve is known as an altitude valve that controls the volume of fuel and water tanks. The altitude valves help prevent overflowing tanks, which is very useful for the fulfillment of processes. The valve remains open until the tank responds to its maximum capacity. When this happens, the valve is automatically closed through the built -in switch.

Some flow control valves are regulated through external channelsWalking such as monitors and meters. These meters or monitors are often designed to send the signal to the valve when the working fluid comes from a certain range of flow or pressure. When this happens, these external devices send a signal to the control valve that continues to open or gets off to help adjust the flow or pressure of the fluid.
