Abstract
The utility model relates to a gas safety self-closing valve which is safe, reliable, can automatically close the valve port in decompression and overpressure situations and cut off the gas source. The self-closing valve comprises a valve body, a pull rod arranged in the valve body and a permanent magnet body arranged under the pull rod, wherein the permanent magnet body is connected with a control rod, a metal sheet is arranged under the permanent magnet body, the metal sheet is fixed on the valve body, the control rod is connected with a fixed connecting rod, the control rod is movably connected with a movable connecting rod, the movable connecting rod is movably connected with a seal valve rod, and a leather diaphragm is arranged between the pull rod and the valve body.
Description
One, technical field:
The utility model relates to a kind of valve of gas pipeline, especially relates to a kind of secure gas self-closing valve.
Two, background technique:
Combustion gas becomes people's indispensable dependence of living, and people understand not comprehensively to the safe handling combustion gas simultaneously, even the use of combustion gas are not had the consciousness of safety precaution, thereby have caused unnecessary loss and accident.Pipeline gas high voltage supply phenomenon takes place in gas voltage adjusting device easily because of environment differs, in the repairing process, then must cut off source of the gas, if the user does not have timely or forgets the valve or the preceding valve of kitchen range of closing burner, when air feed once more, will cause because of artificial gas leakage explosive accident, and personnel and social safety around the entail dangers to.
Three, model utility content:
The utility model provides a kind of secure gas self-closing valve in order to solve the deficiency in the above-mentioned background technology, and it is safe and reliable, can be when decompression and overvoltage the self acting stop valve mouth, cut off source of the gas.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of secure gas self-closing valve, comprise valve body, it is characterized in that: be provided with pull bar in the valve body, the pull bar below is provided with permanent magnet, and permanent magnet is connected with controlling rod, the permanent magnet below is provided with tinsel, tinsel is fixed in valve body, and controlling rod is connected with stationary links, and controlling rod also flexibly connects with movable rod, movable rod and sealed valve stem flexibly connect, and are provided with epithelium between pull bar and the valve body.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
Problems such as the utility model is simple in structure, is easy to install, and need not to regulate, and connecting rod worker formula mechanism stable is reliable, installs to exempt to regulate effectively to have solved existing self closing stop valve because of producing difficult the adjusting, and output is not high.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-seals valve block, 2-epithelium, 3-valve gap, the 4-bolt, 5-carries button, 6-pull bar, 7-permanent magnet, the 8-iron plate, 9-ball valve, 10-air outlet, 11-valve pocket, the 12-fixed support, 13-stationary links, 14-controlling rod, the 15-moving fulcrum, 16-movable rod, the secondary fulcrum of 17-, the 18-sealed valve stem, 19-valve port, 20-valve body.
Five, embodiment:
Referring to Fig. 1, the utility model comprises valve body 20, be provided with pull bar 6 in the valve body 20, pull bar 6 one ends with carry button 5 and be connected, the other end is a bolt 4, pull bar 6 belows are provided with permanent magnet 7, permanent magnet 7 is connected with controlling rod 14, permanent magnet 7 belows are provided with iron plate 8, and iron plate 8 is fixed in valve body 20, and controlling rod 14 is connected with stationary links 13, controlling rod 14 also flexibly connects with movable rod 16, movable rod 16 flexibly connects with sealed valve stem 18, and sealed valve stem 18 1 ends are connected with the sealing valve block at valve port 19 places, are provided with epithelium 2 between pull bar 6 and the valve body 20.
During real work, pipeline normal barometric pressure: mention button 5, because pull bar 6 and permanent magnet 7 the suction effect of inhaling mutually with iron plate 8 greater than permanent magnet 7 mutually will have spacing controlling rod 14 pull-ups down, promote sealed valve stem 18 and seal valve block valve port 19 is opened under the booster action of stationary links 13, movable rod 16.This moment since the effect that epithelium 2 is subjected to manifold pressure heave, thereby reach the purpose of keeping normal air feed.
During the pipeline decompression: because epithelium 2 no longer bears pressure or the pressure that born during less than the suction between permanent magnet 7 and the iron plate 8, controlling rod 14 promoted stationary links 13, movable rod 16, sealed valve stem 18 in the other direction and sealed valve block valve port 19 is closed under the effect of the suction between permanent magnet 7 and the iron plate 8 this moment, reached the purpose of cutting off source of the gas.
Pipeline pressure is too high when exceeding normally-pressured neighbor, because the pressure that epithelium 2 bears is greater than the suction between pull bar 6 and the permanent magnet 7, pull bar 6 and permanent magnet 7 are separated, controlling rod 14 promotes stationary links 13, movable rod 16, sealed valve stem 18 and sealing valve block in the other direction valve port 19 is closed under the effect of the suction between permanent magnet 7 and the iron plate 8, reach the purpose of cutting off source of the gas.
