Gas pressure pneumatic valve maintenance method

the fuel gas pressure of the pneumatic valve maintenance methods are there?
the fuel gas pressure of the pneumatic valve maintenance method has the following:
( Gas pressure of the pneumatic valve cover is used to adjust the volume of air breathing hole, ensure reduced pressure pneumatic valve step-down and voltage stabilizing role, not the plug. In the past, there are many users due to the effect of the above of the don't understand the blowholes, causing gas reduced pressure pneumatic valve clean dirt and don't want to go to, also some people do not pay attention to when a cloth to clean vacuum pneumatic valve, pneumatic valve is often on cover clean, and the breathing hole is in the process of cloth to wipe brush is sundry jam cause an accident. Therefore, in the process of cleaning, if discover to there is congestion, breathing holes available fine wire carefully connect fully, but to prevent puncture or damage to the reduced pressure within the pneumatic valve rubber membrane.
　　( Liquefied petroleum gas cylinders and location if put do not conform to the requirements, has the potential to liquefied petroleum gas into the gas reduced pressure pneumatic valve, causing the rubber sealing ring dissolved, smaller inlet gaps or congestion, affect the normal use. In addition, the rubber sealing ring is wearing parts, use for a long time, due to the effect of corrosion of the liquefied petroleum gas (LPG) and makes it appear pit concave phenomenon, cause air leakage. Therefore, gas pressure pneumatic valve should be check regularly.
　　( Gas pressure of the pneumatic 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 vacuum pneumatic valve cavity, aging caused by leakage of diaphragm after long time. For the sake of safety, these practices are not allowed.
in addition, if the gas pressure of the pneumatic valve fixed mother loosened, or under the tighten, tighten mother silk and the edge of the pneumatic valve cover with the rubber membrane in grinding, can also cause air leakage. Especially the reduced pressure pneumatic valve rubber film falls off locking device or rubber membrane rupture, can cause high pressure gas explosion accidents.
　　( Gas pressure of the pneumatic valve 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, lest reduce pressure pneumatic valve sealing performance and pressure and voltage regulation performance, more to prevent the damage caused by high pressure direct gas removal and cause fire accident.
