Using method explanation:

(as shown in Figure 1), first the movable joint of indoor multifunctional fuel self closing stop valve (30), the gas that is tightened in pipeline gas enters on gas source connector (not have the diagram of connection, be appreciated that), then, press starting bar (27) under firmly, automatically reset elastic force spool (28), pressure regulation drag hook (12) of interlock drives pressure regulation lever (15) to back down elastic force spool (19), now, combustion gas can be normally unimpeded.

(as shown in Figure 2) when the pressure of stopping the supple of gas or steam is ultralow or the loosening accidental of flexible rubber hose is leaked gas, because air pressure in gaseous-pressure chamber (5) becomes to reduce or there is no air pressure, described rubber pressure diaphragm (10) is not subject to atmospheric pressure toward the effect of external force, described elastic force spool (19) even if under the effect of self spring force automatic self-closing gas.

(as shown in Figure 3) as this self closing stop valve uses year aging for a long time, pressure regulation pressure out of control is greater than while setting use value, the pressure regulation drag hook guide sleeve (11) that in described pressure regulation drag hook (12), permanent magnet (14) and iron are made disconnects automatically, now, described rubber pressure diaphragm (10) does not interact with pressure regulation drag hook (12), described elastic force spool (19) is under the effect of self spring force, even if automatic self-closing gas.
