Pressure reducing valves, safety valves, pressure stabilizing valves, pressure relief valves all belong to the pressure valves, mainly the difference in function. Pressure reducing valve is a high pressure medium to reduce the pressure of the medium of low pressure equipment, the valve's characteristics, is in the case of constant changes in the inlet pressure, to maintain the outlet hear pressure and temperature values within a certain range. Safety valve is used to prevent boilers, pressure vessels and other equipment or piping due to overpressure and damage to the valve. When the pressure is slightly higher than the normal working pressure, the safety valve automatically opens, so that the pressure drops. When the pressure is slightly lower than the normal working pressure, the safety valve automatically closes, stops discharging fluid and maintains the seal.

Do you know what the emergency relief valve is used for? In fact, it can be said that it is a safety device to protect the safety of the tanks, because these tanks will sometimes appear due to external forces or internal influences that lead to a sharp rise in pressure, once more than the rated pressure, it is more dangerous, this time it is necessary to release the valve in time to release the excess pressure to protect the tanks will not explode. Of course, want the emergency relief valve to play its role, the correct installation method is necessary, then we know the installation method? If you are not sure, the following editor will talk to you in detail about its use and installation methods.

Nitrogen sealing valve without additional energy, the use of the regulated medium's own energy as a power source. Automatic control of the valve medium flow, so that the pressure after the valve to maintain a constant pressure stabilization device. Valve own internal through the spool, diaphragm, spring and other mechanical components of the mutual action to stabilize the pressure at the outlet P2.

(1) The safety rules stipulate that the opening pressure of the safety valve is 0.115 Mh. When in use, the opening pressure should be adjusted by carefully adjusting the bolts so that it conforms to the specified value. (2)It is necessary to frequently (or regularly) check whether the exhaust situation is normal or not, to prevent the exhaust pipe, valve body and spring from being blocked or bonded by the ash, viscous impurities and other dirt in the acetylene gas stream, to ensure the sensitivity and effectiveness of the safety valve. (3) If the safety valve is found to have leakage or non-stop exhaust phenomenon, it should be stopped immediately.

The answer to the above question usually determines that several protective measures should be used, such as:1. Measures to suppress explosion propagation without emissions.2. Preventive measures for fire + explosion hazards: (daily management and process management to limit the amount of combustible loads).3. Management of anti-static, especially for dusts with a low Minimum Ignition Point (MIE).4. Use of spark detection and elimination techniques, i.e., management and control of the source of spark generation (e.g., grinding, milling). Grinding, milling).

Safety valves, pressure reducing valves, pressure stabilizing valves, pressure relief valves are all pressure valves, mainly because of the difference in function. Safety valves are valves used to prevent damage to boilers, pressure vessels and other equipment or piping due to overpressure. When the pressure is slightly higher than the normal working pressure, the safety valve automatically opens, so that the pressure drops. When the pressure is slightly lower than the normal working pressure, the safety valve automatically closes, stops discharging fluid and maintains the seal.
