Background technology
With social economy, the development of technology, the raising of living standards of the people, it is important that combustion gas has become daily life
The energy；At present, the register one's residence stove used in end, mostly cock-type hand-operated valve of fuel gas pipeline, such gas valve is used for a long time, interior
Abrasion is had between portion's spiral and sealing advance expenditure, gas leakage is caused, is that safety hides some dangers for；Pass manually is needed after use
Close.Or there is under-voltage or superpressure state in combustion gas in use, it is impossible to which the change of sensed pressure, low dose of combustion gas is let out
Leakage（Non-toxic reaction concentration）It can not artificially discover, sustained release reaches on fire and explosion ratio, run into friction, electric spark or fire
Source will cause fire explosion, harm family and neighbourhood's property.Tend to occur property loss difficult to the appraisal, or even life
Safety.
Utility model content：
The purpose of this utility model is to provide a kind of gas self-closing safety valve, can for strengthen gas supply fire safety
By property, and overcome current manually-operated gate above shortcomings.
Gas self-closing safety valve of the present utility model is made up of main valve body, valve element, valve element controlling organization, improvements introduced
It is：There is the groove of circular flat upper port in the middle part of valve body, it is umbrella shape or cylindricality button that a bottom is connected in groove circumference port
Lid, top are the switch base that cylindrical seat is constituted, and spool chamber is formed between the buckle closure and groove of switch base, and described valve element is periphery
Diaphragm of the sealed holding at buckle closure Yu valve body recess junction surface.
Through valve body gas port in valve not along the direct insertion of axis, spool chamber is rolled in the middle part of valve body extending, wherein
Side（Mostly air inlet side）The outlet that gas port is folded to spool chamber is located at below its center, and pelvic outlet plane is parallel with diaphragm, valve
The import that is open as the end gas port of the gas port of the body other end in spool chamber；
Described valve element controlling organization includes：Center of circle fixed magnet with holes at buckle closure and cylindrical seat seam is fixed on, is worn
Cross on the depression bar above the diaphragm depression bar of fixed magnet circle center hole, fixed magnet and moving magnet is installed, with depression bar pilot hole and cylindrical seat
The screw that the safety valve keying that barrel stretches into annular groove is turned round, screwed on the depression bar that depression bar outer end internal thread assembles keying torsion, wherein,
The lower end for stretching into the depression bar of spool chamber is assemblied in the blind hole on diaphragm.
For automatic self-closing gas valve during overpressure of gas in supply air line, set in valve body air inlet side by excessively stream pedestal,
The ball sealer of excessively stream pedestal is blocked during excessively stream, the controller for excess current of ball sealer back-moving spring composition, excessively stream pedestal passes through screw thread
It is assemblied in gas port, ball sealer connecting spring, the other end of spring is fixed on valve body by pressure holding piece.
To prevent children, the elderly of feeblemindedness, intellectually challenged from opening by mistake valve, the depression bar on moving magnet is locked rotation stop
The relatively interior locking convexed into mouthful, constitutes the lockable mechanism of avoiding improper opening on piece, with cylindrical seat side wall.
Advantage and effect of the present utility model：Overpressure of gas situation can effectively be prevented using super stream device.Using with
The lockable mechanism of lock banking stop and locking mouthful, the unlatching of valve needs the action of knob, adds opening program, it is to avoid combustion gas is by youngster
The elderly, the intellectually challenged of virgin or feeblemindedness open by mistake valve, cause combustion gas surprisingly to be revealed.Combustion gas can be reduced using diaphragm seal
The opening of leakage, it is to avoid gas leakage；Using structure of the upper magnetic unit by gaseous-pressure and Magnetic Control, it is possible to achieve
Low pressure is self-closing.Each protection location is independent, is independent of each other, realizes the multiple protective of safety valves for gas；It is easy to operate, use safety
Reliably, both having realized combustion gas high-low pressure can automatically control, and prevent the elderly that children, intelligence decline from opening by mistake valve again.
