Description
Technical field
The present invention relates to a kind of low pressure combustible gas double drives valve.
Background technique
Solenoid valve in the market is to be applicable on the conveyance conduit of mesohigh liquid, gas to use mostly.If when on the pipeline of low pressure combustible gas body, using, can not use during the unregulated power configuration.For example the inflammable gas main component of the biomass pool in rural area generation is that methane pressure has only the 30-40cm water column.Especially in outlying rural area, the place that power supply is not also popularized can not be used.
Summary of the invention
The present invention proposes a kind of low pressure combustible gas double drives valve that uses in a kind of pipeline, be particularly useful on the methane-generating pit pipeline, can effectively prevent the combustion gas tempering, avoid the biomass pool blast for conveying low pressure combustible gas body.
The scheme that the present invention solves its technical problem employing is: low pressure combustible gas double drives valve, by suction tude 1, main valve 2, air intake branch 3, spool 4, draw together valve body 5, Returnning spring 6, electromagnet 7, steam outlet pipe 8, valve pocket 9, O-ring seal 10, pore 11, bellows 12, bellows ante-chamber 13-1, bellows back cavity 13-2, barrier film 14, secondary valve 15 and steam outlet pipe 16 are formed, suction tude 1 is connected with main valve 2 inlets, main valve 2 air outlet pipes link to each other with valve body 5, link to each other with air intake branch 3 again simultaneously, air intake branch 3 links to each other with the import of secondary valve 15, barrier film 14 is divided into two cavitys with bellows 12, i.e. bellows ante-chamber 13-1 and bellows back cavity 13-2; An outlet of secondary valve 15 communicates with steam outlet pipe 16, another outlet communicates with the bellows ante-chamber 13-1 of bellows 12, bellows 12 central longitudinal are to being embedded with barrier film 14, center in bellows back cavity 13-2, spool 4 is bound up with barrier film 14, and the other end of spool is around upper reset spring 6 and stretch in the center cavity of electromagnet 7; The valve pocket 9 of an annular is established in the stage casing of spool 4, and two road seal rings 10 are established at the two ends of valve pocket 9, and the slip of spool 4 can make the outer pipe of main valve 2 and steam outlet pipe 8 UNICOMs on the valve body 5, also has a pore 11 among the bellows back cavity 13-2 and communicates with atmosphere.
The invention has the beneficial effects as follows, can electricity drive, gas drive is dual-purpose.The occasion that power supply is arranged can utilize the effect of electromagnet to open and close valve, during as if unregulated power, can utilize the pressure of combustion gas self to open and close valve.Two seal rings are established at the valve pocket two ends, have guaranteed sealing effect.Simple in structure, easy to use, safe and reliable.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a working state structure schematic representation of the present invention.
Among the figure, 1, suction tude, 2, main valve, 3, air intake branch, 4, spool, 5, valve body, 6, Returnning spring, 7, electromagnet, 8, steam outlet pipe, 9, valve pocket, 10, O-ring seal, 11, pore, 12, bellows, 13, diaphragm cavity, 14, barrier film, 15, secondary valve, 16, steam outlet pipe.
Embodiment
In conjunction with the accompanying drawings 1 and accompanying drawing 2 have a talk about the working procedure of bright low-voltage solenoid valve.Working procedure when working procedure when the electric power dosage is arranged and unregulated power dosage describes respectively.
Working procedure when the electric power dosage is arranged:
At first open main valve 2 during use, energising, this moment, electromagnet 7 generation magnetic force spurred compression reseting spring 6 left with spool 4, and at this moment valve pocket 9 residing positions can be with suction tude 1 and steam outlet pipe 8 UNICOMs, and combustion gas just enters the combustion gas head, can carry out ignition.
When stopping using, stop energising, electromagnet 7 loses magnetic force, and Returnning spring 6 rebounds automatically spool 4 is promoted to the right, valve pocket 9 returning positions, the inflammable gas in the steam outlet pipe 8 is cut off, and burning stops.
Working procedure during the unregulated power dosage:
During use at first with secondary valve 15 to 90 ° of dextrorotation, air intake branch 3 just communicates with bellows chamber 13, opens main valve 2 again, and combustion gas this moment is just by air intake branch 3, secondary valve 15 enters bellows chamber 13, because the pressure of combustion gas promotes barrier film 14 left, the while also is moved to the left compression reseting spring 6 with the spool 4 that barrier film 14 links, at this moment valve pocket 9 residing positions can be with suction tude 1 and steam outlet pipe 8 UNICOMs, combustion gas just enters the combustion gas head, can carry out ignition, sees Fig. 2.If when stopping using, with secondary valve 15 half-twist left, air intake branch 3 cuts off bellows chamber 13 and steam outlet pipe 16 UNICOMs with bellows chamber 13, barrier film 14 is not stressed, Returnning spring 6 returns, and spool 4 moves right, the valve pocket returning position, the inflammable gas in the steam outlet pipe 8 is cut off, and burning stops.
