Gas pressure reducing valve leakage causes and treatment methods

by:Mech     2020-08-14
The cause and management of gas pressure reducing Industrial Valves leakage method all have? ( 1) Under the cause of the gas pressure reducing valve body, cover didn't tighten the screw; The body of the rubber membrane damage; Air inlet seal aging damage. ( 2) Gas pressure reducing valve processing method to tighten the upper and lower lid screw; Replace the rubber membrane; Pressure reducing valve and cylinder junction rubber sealing ring seal gas supply role, it after long-term use will wear, aging, even in the replacement of the cylinder run themselves when they fall off and cause a lot of gas, cause serious accidents. Therefore require every time, replacing the cylinder to install pressure reducing valve, should pay special attention to check whether the rubber seal is in good condition, for the aging, wear and tear, especially when installation, must check whether there is any missing on sealing ring. If already aging or wear, should be replaced in a timely manner, but the cut is not possible with film cut into substitution, must use special seal. ( 3) Gas pressure reducing valve rubber film aging is a common cause of the leak. It is known that there are a lot of users in order to use the bottle bottom spirit cylinders will run backward, heating cylinder with hot water or fire, etc. , this will make gas bottle bottom residue into the cavity in the relief valve, diaphragm aging caused by leakage after long time. For the sake of safety, these practices are not allowed. In addition, if the gas pressure reducing Industrial Valves fixed mother loosened, or under the tighten, tighten mother silk and the edge of the bonnet with the rubber membrane on the ground broken, can also cause air leakage. Especially the pressure reducing valve rubber membrane locking device fall off or rubber membrane rupture, can cause high pressure gas explosion accidents. ( 4) Gas pressure reducing valve's structure is tight, products are carefully debugging assembly and before they go out from the factory after strict inspection, so the connection screw, adjust parts such as do not allow the users to remove or twist to touch, so as not to reduce the pressure reducing Industrial Valves sealing performance and step-down voltage regulation performance, more to prevent the damage caused by high pressure direct gas removal and cause fire accident.
