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.
In addition, sensing devices such as existing alarm can only be reported to the police when gas leakage, can't cut off source of the gas automatically, have certain potential safety hazard.
Three, model utility content:
The utility model provides a kind of secure gas self-closing valve in order to solve above-mentioned deficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of gas safe solenoid valve, comprise valve body, it is characterized in that: be provided with the electromagnetic coil that is connected with the electrical signal reception unit in the described valve body, the electromagnetic coil below is provided with fixed magnet, fixed magnet one side is provided with movable core, the movable core top is provided with spring, be provided with epithelium in the valve body, described epithelium is arranged between pull bar and the movable magnet, and secured core and movable core are arranged on the pull bar, movable magnet is connected with the spool controlling rod, movable magnet is arranged with iron plate, is connected with connecting rod on the described spool controlling rod, and connecting rod is provided with piston rod.
Described spool controlling rod is provided with sliding fulcrum, and described connecting rod is divided into stationary links A and movable rod B, and stationary links A and spool controlling rod are for fixedlying connected, and movable rod B and spool controlling rod are for flexibly connecting.
Be connected with on the described pull bar and carry button.
Described piston rod is provided with the sealing valve pad.
Compared with prior art, the advantage and the effect that the utlity model has are as follows:
The utility model is simple in structure, is easy to install, and need not to regulate, and reliable and stable, particularly electromagnet portion can be cut off combustion gas immediately when gas leakage, prevents output, has filled up the blank of prior art.
Four, description of drawings:
Fig. 1 is a structural representation of the present utility model.
Description of reference numerals: 1, suction port 2, valve body 3, movable core 4, signal wires 5, valve gap 6, secured core 7, carry button 8, pull bar 9, electromagnetic coil 10, spring 11, fixed magnet 12, epithelium 13, cock ball valve 14, air outlet 15, iron plate 16, fixed support 17, stationary links A18, spool controlling rod 19, sliding fulcrum 20, movable magnet 21, movable rod B22, moving fulcrum 23, piston rod 24, valve pocket 25, valve port 26, sealing valve pad.
Five, embodiment:
Referring to Fig. 1, a kind of gas safe solenoid valve, comprise valve body, be provided with the electromagnetic coil 9 that is connected with electrical signal reception unit (signal wires 4) in the described valve body, electromagnetic coil 9 belows are provided with fixed magnet 11, fixed magnet 11 1 sides are provided with movable core 3, movable core 3 tops are provided with spring 10, movable core 3, fixed magnet 11, spring 10 is arranged in the valve gap 5, be provided with epithelium 12 in the valve pocket 24 of valve body, epithelium 12 is arranged between pull bar 8 and the movable magnet 20, secured core 6 and movable core 3 are arranged on the pull bar 8, be connected with on the pull bar 8 and carry button 7, movable magnet 20 is connected with spool controlling rod 18, and movable magnet 20 is arranged with iron plate 15, be connected with connecting rod on the described spool controlling rod 18, movable rod B21 is provided with piston rod 23, and piston rod 23 is connected with movable rod B21 by moving fulcrum 22, is connected with sealing valve pad 26 on the piston rod 23.Described spool controlling rod 18 is provided with sliding fulcrum 19, stationary links A17 and movable rod B21 on the sliding fulcrum 19.
Working principle of the present utility model: pipeline normal barometric pressure: mention button 7, because the suction of pull bar 8 and movable magnet 20 is greater than movable magnet 20 and iron plate 15 power mutually, therefore spool controlling rod 18 will be pulled up simultaneously, stationary links A17 (stationary links A17 is fixed in the valve pocket 24 by fixed support 16), movable rod B21 promotes piston rod 23 under auxiliary effect, because of sealing valve pad 26 is connected with piston rod 23, therefore valve port 25 is opened, gas enters in the valve body 2 through suction port 1 because epithelium 12 is subjected to the effect of manifold pressure heaves, 14 give user's air feed through the air outlet again through cock ball valve 13, thereby reach the purpose of keeping normal air feed.
During the pipeline decompression: because epithelium 12 no longer bears pressure or the pressure that born during less than the suction between movable magnet 20 and the iron plate 15, because under the effect of gravity, spool controlling rod 18 promotes stationary links A17, movable rod B21 in the other direction under the effect of the suction between movable magnet 20 and the iron plate 15 at this moment, piston rod 23 is closed valve port 25, reaches the purpose of cutting off source of the gas.
Pipeline pressure is too high when exceeding normally-pressured neighbor: because the pressure that epithelium 12 bears separates spool controlling rod 18 and movable magnet 20 greater than the suction between pull bar 8 and the movable magnet 20, under the downward thrust of spool controlling rod 18 and iron plate 15 (maintaining certain suction under the spacing effect), stationary links A17, movable rod B21, piston rod 23 are closed valve port, reach the purpose of cutting off source of the gas.
Electromagnet portion when work: pull to the extreme higher position movable core 3 pull-ups are simultaneously inhaled mutually with secured core 6 function that (so the suction between iron core while pull-up and the fixed magnet is pulled together greater than the elastic force of spring 10) do not influence above-mentioned former self closing stop valve carrying button 7, arrange mutually and tear the principle that heteropole is inhaled mutually open owing to the distinctive homopolarity of magnetic when when electromagnetic coil 9 receives electrical signal by sensor or prober, producing with secured core 6 same pole, under the effect of spring force, promote movable core 3 down, thereby this moment is because the pressure that elastic force bears greater than epithelium 12 makes movable magnet 3 and fixed iron piece 15 inhale close port mutually promptly turn-offs combustion gas and prevent to export.
The utility model plays a part conventional self closing stop valve when no electric circuit, when sensor or alarm send signal, have the function of solenoid valve.In addition, it also has warning function, can cut off source of the gas when reporting to the police.
