The basic properties of the gas valve in the use of gas users , the valve is often detachable . Installation, the valve and the cylinder connection ( installation ) are correct and secure , for the use of safety-critical , specific installation and maintenance requirements are as follows .

Installation : Replace cylinder , install the valve when the first note on the positive, good threaded on , then press the Left-hand direction ( counterclockwise ) rotation of the handwheel . Rotation, not too much force , the right hand should be the ease, or it may thread misalignment , this time not forced precession should be recalibrated before screwed up screwed up . If installed properly, hand jiggle valve body does not shake or loose feeling around ; if the installation is bad, even if the handle tightened round , but did not because a good thread , so jiggle valve body will there are loose movement .

Leak Detection Methods: In order to ensure the safe use of the Shang Hao valve , you can brush at the interface soapy water to check for leaks observed . As with pressure relief valve to close the Show Table Angle after sniffing whether tainted smell, observe whether the pointer has changed . Valve inlet side of the rubber seals are used to prevent leakage of an important component of each replacement of LPG cylinders should be checked that the seal is intact , if deformed or damaged, it must be replaced before use . According to the analysis of poisoning occurred in the past , the explosion of view, there are more than 60% is due to valve or rubber seals without Shanghao loss, damage caused , so to learn , be noted.

Gas valve maintenance methods:

    ( A ) valve atop the breathing hole is used to adjust the amount of air from the buck and ensure the role of regulator valve , and can not be blocked. In the past, many users do not understand the breathing holes because these effects , resulting in valve has dirty unbearable than go clean with a cloth and some people do not pay attention to clean the valve is often clean the valve cover , while the breathing hole was in the process of being wipe with a cloth clogged causing the accident. Therefore, during the cleaning process , if found breathing holes are blocked , the available transparent thin wire carefully , but to prevent puncture or damage the rubber membrane valve .

( 2 ) If the position of LPG cylinders and put Debu meet the requirements, it is possible to make liquefied petroleum gas flow valve, resulting in dissolution of the rubber seals swell , so that the inlet gap smaller or blockage of normal use. In addition , the rubber seals are wearing parts, long-term use , due to the corrosive effects of LPG to make it appear crater phenomenon, resulting in leakage. Therefore, should be checked regularly.

( 3 ) valve is caused by the aging of the rubber membrane leak a common cause . It is understood that there are many users will be emboldened to run out of gas cylinders upside down bottle with hot water or heat for gas cylinders , etc., which would make the gas bottle debris from entering the valve cavity , after a long time after aging caused by the diaphragm leakage. For safety, these practices are not allowed.

Also , if the moving valve fixed mother worked loose or tightening the parent yarn is fastened on the valve cover to grind the edge of the rubber film broken, will cause leakage. Especially rubber membrane valve locking device off or rubber membrane rupture , can cause high pressure plenum and explosion .

( 4 ) reducing valve structure is relatively tight, products manufactured before assembly and commissioning are carefully through rigorous testing before the factory , so the connection screw and adjust parts allow users to disassemble or tamper with random twist , so reducing pressure valve sealing performance and buck regulator performance , but also to prevent damage caused by high-pressure direct aspirated demolition caused fires.
