The pressure reducing valve for the gas pressure regulating device is also called the immediate efficiency regulating valve, and is equipped with a valve. This is a device that maintains the pressure regulating valve and makes it safe to operate. It is a data signal device in which the pressure regulating valve is abnormal. If the inlet and outlet working pressure rises autonomously and exceeds the required approval value due to valve gasket, valve damage or other reasons, the valve will automatically open the exhaust pipe. The pressure chamber is connected to the cylinder, and the bottom pressure chamber is a vapor inlet and outlet, and leads to the application system software.
The range of the pressure gauge is the working pressure of the storage vapor in the cylinder. The inlet and outlet working pressure of the bottom gauge can be manipulated by adjusting the extruder screw. When applying, first open the gas cylinder main gate, then rotate the bottom pressure gauge working pressure clockwise to adjust the extruder screw, so that the main elastic yellow and the transmission system plastic film, the elastic yellow protective layer pad and the ejector rod are opened to open the valve. . The imported pressurized steam is relieved by the gas pressure regulating device with a pressure reducing valve and then moved into the bottom pressure chamber, and passes through the inlet and outlet to the working system software. Rotate and adjust the extruder screw to change the aspect ratio of the valve opening, and then adjust the amount of the pressurized steam and exceed the required working pressure.
The use of the pressure reducing valve for the gas pressure regulating device is as follows:
(1) Pressure reducing valves are available in many sizes depending on the requirements of use. The highest import pressure is mostly, the minimum import pressure is not less than 2.5 times the export pressure. There are many export pressure specifications, generally, the highest outlet pressure is. Usually, the gas supply pressure reducer is required for the centralized gas supply pipeline, and the gas pressure collector, the oxygen gas collection bag and the like are not equipped with the gas pressure reducer.
(2) When installing the pressure reducing valve for the gas pressure regulating device, determine whether the connection specification is consistent with the cylinder and the joint of the system. The gas pressure regulating device uses a pressure reducing valve and the cylinder is connected with a hemispherical surface, and the nut is tightly fitted by tightening the nut. Therefore, it is necessary to maintain the smoothness of the two hemispheres during application to ensure a good airtight effect. High pressure gas can be used to blow off dust before installation. If necessary, a material such as polytetrafluoroethylene may be used as the gasket.
(3) Pressure reducing valve for gas pressure regulating device should be strictly prohibited from contact with grease to avoid fire accident.
(4) When the work is terminated, the residual gas in the pressure regulating valve should be drained, and then screwed down to adjust the extruder screw to prevent the elastic component from being deformed for a long time.
(5) The pressure reducing valve for the gas pressure regulating device should avoid impact vibration and should not be in contact with corrosive substances.
