Regulator is a pressure regulating device which acts as a conduit and regulate and stabilize the gas pressure is out of the tube so that the gas stream becomes constant.
The main function Pressure Regulator (pressure regulator) is to match the flow of gas through the regulator to the demand for gas placed upon the system. If the load flow is reduced, then the current regulator should also declined. If the increase in the load current, then the current regulator must increase to keep the controlled pressure from the decline due to a shortage of gas in the system pressure.
A pressure regulator include a limiting element, the element loading, and measuring elements: limiting element is the type of valve. It could be a globe valves, butterfly valves, small valves, or other types of valves capable of operating as a variable flow restriction. Loading element applying the force required for restricting element. It can be many things such as weight, a spring, a piston actuator, or more commonly in combination with diaphragm actuator springs. When the actuator is forced against the disk expansion, force is distributed between the wall pressure. This allows gas to flow at an appropriate pace and will not continue to evaporate and diluted. Measuring element determines when the inlet flow equal to the flow rate. The diaphragm is often used as a measuring element since it can also function as a combined element.
