Description
Technical field
The utility model relates to a kind of pipeline gas valve, particularly a kind of electromagnetism self closing stop valve.
Background technique
Along with extensively popularizing of gas application, various gas accidentses are also the gesture of significantly rising, have caused huge injures and deaths and loss to resident's the security of the lives and property.In order to reduce the generation of gas accidents, the safety precaution facility that existing indoor installation is commonly used generally has two kinds: one is mechanical overcurrent self closing stop valve, mainly to utilize the air pressure of gas ductwork self to keep combustion gas normally to export, in the time that pipe network is stopped the supple of gas or steam suddenly, decompression also realizes and automatically closing under spring or magnetic force in self closing stop valve, and can avoid sends someone to visit before air feed notifies user first to close valvular worry; But this self closing stop valve can not cut out the micro-leakage of combustion gas, more can not realize closely and controlling.Another kind is the solenoid valve with leakage alarm, and its effect is that alarm sends chimes of doom output current when reach certain concentration after gas leakage in air time, makes solenoid valve reset to realize and cuts off combustion gas output; But this solenoid valve function singleness, meet the unexpected Shi Buhui that stops the supple of gas or steam suddenly and automatically close, and before pipe network recovers air feed, the staff of gas company must visit and notify user to close all gas valves, in case cause secondary leakage at pipe network.Like this, both expended larger manpower, and can not ensure in time again and affect section resident's normal life by air feed.
Model utility content
The object of the utility model is: a kind of normal output that utilizes pipe network self air pressure to keep combustion gas is provided, when pipe network is stopped the supple of gas or steam suddenly in work, can automatically close the electromagnetism self closing stop valve that can automatically close in the time that external alarm detects that gas leakage sounds the alarm and exports control electric current.
In order to reach above-mentioned object, the technical solution of the utility model is: the waist in valve gap is provided with annular diskette, and top is provided with electromagnetic coil and support thereof; Intert an iron core in the middle of support, iron core upper end is connected in series with carrying handle by screw, iron core lower end and pull bar immediately, pull bar bottom end face and bracelet diaphragm snapping, ring magnet is fastened on the top of pull bar.
Described coil brace, in the time of valve opening, plays spacing effect simultaneously.
Described ring magnet, between coil brace and annular diskette, moves up and down with pull bar in valve switch process, and the polarity of itself and coil opposing side is the same sex.
Described pull bar is nonmagnetic substance, and the end face diameter of bottom and bracelet diaphragm snapping is greater than the diameter of taper valve port.
The thickness of described bracelet diaphragm intermediate portion is greater than its peripheral thickness, plays sealing in the time of valve closing state.
Above-mentioned electromagnetism self closing stop valve, owing to having utilized the gas pressure of gas ductwork self, in the time opening valve, air pressure sticks out diaphragm to keep the normal output of combustion gas; In the time that pipe network is stopped the supple of gas or steam suddenly, pressure drop, causes the pressure summation that diaphragm bears to be less than ring magnet to the suction between annular diskette, and valve is closed automatically; Before recovery air feed, visiting without sending someone to notify and get final product direct air feed in gas company, has effectively ensured timely ventilation, also saves manpower.On the other hand, when pipeline, burner or the interface after valve occurs gas leakage because of various situations, external alarm sounds the alarm, and output is simultaneously controlled electric current and electromagnetic coil obtained electric valve is closed automatically.Such electromagnetism self closing stop valve, simple in structure, safe and reliable, be connected easily and realize closely and automatically controlling with the control apparatus such as alarm.

Embodiment
Below in conjunction with drawings and embodiments, the utility model is described further.
As shown in Figure 1 and Figure 2, the waist in valve gap 2 is provided with annular diskette 7, and top is provided with electromagnetic coil 3 and support 4 thereof; Intert an iron core 6 in the middle of support, iron core upper end is connected in series with carrying handle 9 by screw 12, iron core lower end and pull bar 5 immediately, pull bar bottom end face and bracelet diaphragm 10 snappings, ring magnet 8 is fastened on the top of pull bar 5.Described coil brace 4, in the time of valve opening, plays spacing effect simultaneously.Described ring magnet 8, between coil brace 4 and annular diskette 7, moves up and down with pull bar 5 in valve switch process.Described pull bar 5 is nonmagnetic substance, and the end face diameter of bottom and diaphragm 10 snappings is greater than the diameter of taper valve port.The thickness of described bracelet diaphragm 10 intermediate portions is greater than its peripheral thickness, plays sealing in the time of valve closing state.
Working procedure of the present utility model is: open before gas, because ring magnet 8 is near annular diskette 7, under magnetic force, is pressed down the intermediate portion of diaphragm 10 and valve port 11 are sealed by pull bar 5, now, valve, in closed condition, does not have combustion gas output.
While opening gas, be pulled upwardly artificially carrying handle 9, until ring magnet 8 is spacing by coil brace 4, pulling force is by iron core 6, pull bar 5 by the intermediate portion pull-up of diaphragm 10, and result combustion gas enters in valve pocket by valve port 11; At this moment, diaphragm 10 pressurizeds are upwards heaved, and meanwhile, make ring magnet 8 depart from annular diskette 7, and in the time that suction is between the two reduced to the summation that is less than diaphragm 10 suffered upward pressures, valve port 11 is held open state, and combustion gas is stable output through air outlet.
In using process, if interrupted because a variety of causes causes pipe network air feed, result declines valve pocket internal air pressure; In the time that the pressure summation that diaphragm 10 bears is less than ring magnet 8 to suction between annular diskette 7, ring magnet 8 forces pull bar 5, iron core 6, carrying handle 9 to move down, until valve port 11 is sealed in the intermediate portion of diaphragm 10; Now, because ring magnet 8 has approached whole suction to the magnetic force between annular diskette 7, sealing is the strongest.By the time, while again recovering air feed, the staff of gas company need not visit and just notify directly air feed, valve port 11 also there is no combustion gas output; Like this, a large amount of manpowers in gas company were both saved, again for recovering as early as possible air feed and ensureing that resident has supplied guarantee by air lift safely.
On the other hand, if when the utility model is external leakage alarm, in use, because appearring in a variety of causes, gas leakage trigger alarm device report to the police, at this moment, electric current is controlled in alarm output makes electromagnetic coil 3 obtain electric work, and the electromagnetic force that coil produces is except attracting iron core 6, also with ring magnet 8 two like magnetic poles repel each others, like this, two bursts of strength force pull bar 5, iron core 6, carrying handle 9 to move down, until valve port 11 is sealed in the intermediate portion of diaphragm 10, have cut off in time combustion gas output.Now, because ring magnet 8 is near annular diskette 7, suction has also approached whole suction between the two, and when electromagnetic coil 3 dead electricity, valve port 11 closes in the same old way.So just can avoid poisoning, the blast that causes because of gas leakage and the generation of fire accident, effectively ensure the safety of resident's lives and properties.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
