Description
Technical field
The utility model relates to a kind of gas safe heat supply proportion control emergency cut-off switch valve, belongs to gas safe and regulates the control technology field.
Background technology
Existing gas safe heat supply ratio control system mainly is made up of solenoid, sleeve pipe, moving iron core, sealing block etc. with the emergency cut-off switch valve, and it mainly acts on is the opening and closing runners.Defectives such as noise is big because the difference on the structural design, existing emergency cut-off switch valve ubiquity, closing velocity slow, be not closed completely.
Summary of the invention
The purpose of this utility model provides a kind of reasonable in design, can effectively realize the gas safe heat supply proportion control emergency cut-off switch valve of tight, the quick opening and closing of runner.
The utility model is a gas safe heat supply proportion control emergency cut-off switch valve, comprise solenoid, place static iron core and moving iron core in the solenoid, it is characterized in that the bottom of moving iron core is provided with the rubber seal piece of band pagoda-shaped back-moving spring, the side of described rubber seal piece is provided with the inlet chamber of bringing gas port into, and the bottom is provided with the primary valve of taking air cavity out of.During work, by the electric or dead electricity that gets of solenoid, the coupling by back-moving spring and moving iron-core coil electromagnetic attraction characteristic makes on the rubber seal piece and carries or move down, and opens or closes primary valve, realizes the break-make to fuel gas path.
Described moving iron core also can be provided with sleeve pipe outward, to isolate inner combustion gas and outside atmosphere, guarantees safety; Also can be provided with cushion pad between described moving iron core and the static iron core, to eliminate the strike note that produces when moving iron core moves.
Also can be provided with screen pack between described air inlet and the inlet chamber,, strengthen the reliable in action of valve body, prolong the service life of valve body to filter the impurity in the combustion gas.
Also can be provided with pad between described back-moving spring and the rubber seal piece, to guarantee the connection reliability between rubber seal piece and the moving iron core.
Also can be provided with magnetic conductive board on the described static iron core, in order to be communicated with magnetic loop.
The utility model compared with prior art has following outstanding advantage and good effect:
1, back-moving spring adopts the pagoda-shaped shape, make between sealing block and the moving iron core easy to assembly, when opening or closing stressed evenly, reliability and quick closedown when having guaranteed to turn round do not have leakage;
2, moving iron core is provided with sleeve pipe outward, both can isolate inner combustion gas and outside atmosphere, guarantees safety; Can make after the iron core dead electricity again and no remanent magnetism generation between the static iron core, realize quick closedown;
3, on the moving iron core cushion pad is set, makes the utility model when action, not have strike note, can effectively reduce noise, increase the service life.
The utility model is by the electric or dead electricity that gets of solenoid, solenoid suction by back-moving spring servo-actuated iron core, make the rubber seal piece carry or move down on rapidly, can in＜1 second time, open or close primary valve rapidly, effectively realize tight, the opening and closing fast of runner.Be suitable in the fields such as flame control, boiler control, domestic heating and accurate proportion control of combustion apparatus and the supporting use of gas safe heat supply ratio control system.
Description of drawings
Accompanying drawing is an overall structure cutaway view of the present utility model.
The specific embodiment
The utility model is mainly by the solenoid 1 of being with magnetic conductive board 2, place the moving iron core 5 of static iron core 3 in the solenoid 1, sleeve pipe 6, band cushion pad 4, place the bottom band pagoda-shaped back-moving spring 7 of moving iron core 5 and the rubber seal piece 9 of pad 8, the formations such as primary valve 11 that inlet chamber 10, the bottom that places the side of rubber seal piece 9 to bring gas port 13 and screen pack 14 into taken air cavity 12 out of.
Below in conjunction with embodiment structure of the present utility model and operation principle are further described:
During work, combustion gas enters inlet chamber 10 by air inlet 13 through filter screen 14.The closed loop magnetic conductive loop is drawn close to the minimum reluctance direction under the effect of magnetic field, magnetic conductive board 2, static iron core 3, moving iron core 5 are formed a magnetic conductive loop, gap maximum between static iron core 3 and the moving iron core 5, reach 4.5mm, therefore produce magnetic field in solenoid 1 energising back and act in the above-mentioned magnetic conductive loop, cause moving iron core 5 that the upwards power of adhesive has been arranged.It upwards promotes after overcoming the gravity of the spring force, pad 8, rubber seal piece 9 of back-moving spring 7, moving iron core 5 and valve port pressure reduction, contact with sleeve pipe 6 end faces by cushion pad 4 earlier on earth the time in adhesive, the rubber of cushion pad 4 is inwardly extruded until moving iron core 5 and the complete adhesive of sleeve pipe 6 end faces, mention pad 8 and rubber seal piece 9 simultaneously, thereby open primary valve 11, combustion gas enters outlet chamber 12 by inlet chamber 10 through primary valve 11.
When closing after the utility model operate as normal, upwards suction elimination of iron core 5 is moved in solenoid 1 outage, owing to have sleeve pipe 6 isolated in the middle of moving iron core 5 and the static iron core 3, the effect of its remanent magnetism generation is minimum, can ignore.Under the effect of deadweight and back-moving spring 7 spring forces, rubber seal piece 9 moves down, and closes primary valve 11.Because of having with rubber seal piece 9, moving iron core 5 necessarily links closely and the gap, back-moving spring 7 is the pagoda shape, rubber seal piece 9 has to the center downward active force in downward process, even primary valve 11 has out-of-flatness or impurity is arranged on primary valve 11, rubber seal piece 9 also has automatic regulatory function, guarantees the zero leakage when primary valve 11 is closed.
Back-moving spring 7 is complementary through measuring and calculating mechanical property and stroke, can guarantee the mechanical property requirements of encapsulant minimum pressure and quick closedown, quick closedown in＜1 second.
