A pressure regulator is a control valve that reduces the fluid inlet pressure to a desired value at its output. The regulator is used for gases and liquids, and it can be an integral device with output pressure settings, either a limiter and a sensor in one body, or a separate pressure sensor, controller or volute current.

Single stage regulator pressure regulator:

High pressure gas is fed from the source through the inlet valve. The gas then enters the body from the regulator, which is controlled by the valve. In this case, the pressure increases, which pushes the shutter and closes the input valve connected to it, and prevents any more gas from entering the regulator. A pressure gauge is installed on the outlet side. . The gas is drawn from the outlet side and the pressure inside the body is adjusted.

The diaphragms are pressurized and the valve opens, and more gas enters the source to balance the output pressure and SPRING. Therefore, the output pressure in the spring force can be adjusted using a handle or knob. Output pressure and inlet pressure keeps aperture / POPPET in closed position. Against the SPRING force.

If the source pressure drops, because the SPRING pressure is increased, it allows more gas and higher pressure to be made in the output chamber to achieve the balance pressure. Therefore, if the source pressure drops, output pressure will increase. The output pressure is falling under the pressure of supply.


Two-stage regulator pressure regulator:

Includes two single stage regulators, which are gradually replaced in two stages in order to reduce pressure. The first stage, which is predetermined, reduces the gas supply pressure to an intermediate stage and the gas is in the pressure to the second stage. The gas is currently set at the pressure (work pressure) set by the control knob setting to the aperture. The two-stage regulator has two safety valves, so that it does not occur in the event of any excessive explosion. The problem with a single-stage regulator requires a constant torque setting.

If the source pressure drops, the output pressure is increased, which requires the torque adjustment. In the two-step setting, there is an automatic compensation for each drop in supply pressure. A single stage regulator may be used with pipelines and cylinders. Two-stage cylinders and manifolds are used.


Pressure Regulator Function:

The primary function of a pressure regulator is to match the gas flow through the regulator to the gas demand, while the output pressure is constant.

If the flow rate decreases, then the regulator flow should also be reduced. If the flow rate increases, then the regulator flow must increase the pressure in order to maintain control of the pressure reduction, due to a shortage of gas in the system. A pressure regulator includes an self-healing element, a loading element, and an element of measurement Is:

• The Volodya loading element can be used to restrict force. Such as GLOBE VALVE, BUTTERFLY VALVE, POPPET VALVE and ...

• Measurement element functions to determine when the input current is equal to the output stream. The diaphragm itself is often used as a measurement element; it can be used as a hybrid element.

In the single-stage regulator image, a force equilibrium on the aperture is used to control a valve in order to adjust the pressure. With the input pressure, SPRING above the diaphragm pushes it downward on the valve, to adjust the pressure. When the input pressure is introduced, the POPPET opens and allows the flow to reach the aperture and the pressure in the enclosure increases, as long as the aperture is upward against the SPRING

Pushing down, decreasing the POPPET current, eventually stopping further pressure increase. By adjusting the upper screw, the downward pressure on the aperture can be increased, so the need for more pressure in the upper chamber is to maintain balance.
