Installation points of self-closing valve
When the pressure regulator is installed, the pressure regulator will be emptied instantaneously during the tightening process, which is a normal phenomenon caused by the gas storage between the cylinder rotary valve and the self-closing valve.
Steps to properly install a self-closing valve:
1. Before installing the self-closing valve, make sure that the valve is closed.
2. When the pressure regulator is installed, the pressure regulator will be emptied instantaneously during the tightening process, which is a normal phenomenon caused by the gas storage between the cylinder rotary valve and the self-closing valve.
3. In the process of tightening the regulator, the user feels that he has tightened it, but it is not actually screwed in place. He just pushed the self-closing valve to two-thirds of the way. At this point, he opens the rotary valve so he can vent his gas. However, because the regulator was not screwed in place, it caused an air leak.
4. Since the self-closing structure added by the new angle valve has a certain elastic spring structure, it needs to overcome a large resistance when installing the self-closing valve. Change the force habit installed on the old valve) to ensure that the self-closing valve is installed in place.
5. After tightening the regulator, the user opens the rotary valve, but cannot exhaust. The main reason is that the user uses a non-standard pressure regulator or the aging screw of the pressure regulator is oxidized, so that the pressure regulator does not fully tighten the angle valve interface, and the front end interface of the pressure regulator fails to open the self-closing valve.
6. Open the valve handwheel of the liquefied gas cylinder, and evenly apply soapy water, detergent and other leak detection liquids on the connecting threads of the self-closing valve and the angle valve, and observe for at least one minute. If there are no air bubbles, it means that there is no leakage, and the installation is qualified; if it is, it means that the installation problem needs to be re-checked. After using liquefied gas, close the handwheel of the liquefied gas cylinder valve.
The installation of the self-closing valve is convenient. As long as the gas self-closing valve is installed at the outlet of the household gas valve, it can be connected to the gas appliance with a hose or a metal bellows, without any accessories such as power cord, signal line or battery. .
The detection is convenient, users can test the performance and sealing effect of the gas self-closing valve by themselves, and complete the test in three steps. First, close the main gas valve and ignite (no ignition); second, open the main gas valve and continue to ignite (not ignite); the third step, gently press the red button above the gas self-closing valve, continue to ignite (not ignite), Normal use. If the gas leakage causes the gas self-closing valve to close, the user should first close the gas main valve to check the cause of the gas leakage, and then open the gas main valve after the gas leakage cause has been dealt with, and then gently press the red button above the gas self-closing valve to ignite at any time. Normal use.
The material of the gas self-closing valve is made of good copper, which is formed by red stamping process. After more than 100 machining processes, more than 20 parts are assembled. A single air flow is specially designed to enter the cavity of the valve body, and automatically generate four spiral air flows to exhaust and burn in the gas appliance, so that the gas appliance burns more completely, has stronger firepower, saves gas, and reduces carbon dioxide emissions, which can not only achieve gas protection, but also Can achieve energy saving and environmental protection.
