The total valve of my natural gas was closed by the attitude I tried. Now I can't open it. I need to use gas. Who knows how to drive it? What skills do I have? I'm talking about the main valve.
General domestic weather is more ball valve, counterclockwise turn 90 degrees can.
Are you talking about using air? Or your valve is a pneumatic emergency shut-off valve
First of all, you have to determine the direction of the valve opening, usually homeopathy, it is off, the reverse is open. First: to determine the opening of the valve, are generally ball valve, screw 90 degrees on it. Second. At the top of your house, there is a button that can be pulled out. It's different from place to place. Some are pulled out half, and some are pulled out. Third: in the following there is a black disk like thing, commonly known as the gas sound core. This is the same as the second, pull out half or all, so that you can use gas, ha ha!
