Technological scheme:
According to above-mentioned purpose, the utility model provides a kind of super flow self-closing gas pressure regulator, governor that leaks gas, and it comprises lower shell body and upper shell; Lower shell body has the gas-entered passageway being interconnected, super flow leakage self-closing valve seat, pressure regulation mouth, gaseous-pressure chamber, outlet passageway; At an installation handwheel of gas-entered passageway front end installing; Pressure regulation lever is installed on the lever strong point, and one end is inserted pressure regulation and taken off in wooden fork pull bar, and the other end is lived and is connected with pressure regulation push rod, and aims at and match with pressure regulation mouth at pressure regulation plug of pressure regulation push rod end installing, to reach the effect of flexible automatic adjustment suction pressure; Between upper shell and lower shell body, clamp a pressure regulation elastomer diaphragm, and at pressure regulation elastomer diaphragm center position, install a pressure regulation and take off wooden fork pull bar, rely on the pressure that pressure regulation elastomer diaphragm outwards expands to drive pressure regulation lever to adjust the effect of suction pressure to reach; It is characterized in that: in gas-entered passageway appropriate position, installing one is subject to the glding type that micro-force spring hauls and closes spool, or the glding type that micro-force spring heads on is closed spool, or Free-rolling formula ball spool matches with super flow leakage self-closing valve seat, to reach the effect of automatically closing combustion gas in the time that unexpected super flow leaks gas forward; In upper shell top center position, install an artificial pressure regulation rotation knob and can slide up and down rise-fall type spring cover cap with inside and match, make adjusting draw different suction pressures with the side of reaching, meet the effect that people use in the gas of different combustion values; Between pressure regulation elastomer diaphragm and spring cover cap, install a pressure adjusting spring and mutually head on and match, to reach the effect that keeps constant charge pressure in effective pilot pressure chamber.
Beneficial effect:
The super flow of one that the utility model the provides self-closing gas pressure regulator, governor beneficial effect that leaks gas is: simple in structure, Safety performance is reliable, and in use not needing to start in addition combustion gas can be unimpeded, user makes, do not need to safeguard, long service life, can prevent trouble before it happens.
