Selection of valve:

Select the type of pressure reducing valve and the pressure regulating accuracy according to the requirements of use, and then select the required diameter according to the required maximum output flow. When determining the valve air source pressure, the air source pressure should be greater than the maximum output pressure of 0.1 MPa. The valve is generally installed after the water diversion filter and in front of the direct-acting solenoid valve manufacturer's lubricator or setting device, and be careful not to reverse the inlet and outlet; when the valve is not used, the knob should be loosened to prevent the diaphragm from being deformed under constant pressure. , Affect valve performance.

The following items should be paid attention to when installing and maintaining the valve:

In order to facilitate operation and maintenance, the valve is generally installed vertically on a horizontal pipeline.

When installing, make sure that the direction of the medium flow in the pipeline is consistent with the direction of the arrow shown on the valve.

In order to prevent excessive pressure behind the valve, a pressure reducing valve should be installed within 4M from the valve outlet.

The following issues should be paid attention to when using rubber hoses in the valve:

The rubber hose in the gas pressure reducing valve must be pressure tested, the oxygen hose must be tested at 20 atmospheres, and the acetylene hose must be tested at 5 atmospheres. Rubber hoses that have not undergone pressure test, deterioration, aging, brittleness, or air leakage shall not be used.

The length of the hose in the gas pressure reducing valve is generally between 10-20 meters. The water heater solenoid valve manufacturer is not allowed to use a hose that is too short or too long. The exit must be fixed together with special clips or annealed wire.

The oxygen hose is red in the gas pressure reducing valve, and the acetylene hose is black. Don't make mistakes when connecting with the welding torch.

During the use of the gas pressure reducing valve, when the acetylene hose falls off or ruptures and catches fire, the flame on the welding torch or cutting torch should be extinguished before the gas supply is stopped. After the oxygen hose catches fire, immediately close the oxygen cylinder valve and stop the oxygen supply. It is forbidden to use bending method to eliminate the fire of oxygen hose. When the acetylene tube is on fire, the fire can be extinguished by bending the previous section.

5. It is forbidden to install rubber hoses in gas pressure relief valves on high-temperature pipelines and wires, or press heavy or hot objects onto the hoses, nor connect the hoses with electric welding wires. Prevent cuts when using it. The hose should be sheathed or capped when it passes through the driving route.
