The flameproof effect can be achieved in coal mining, combustible gas and steam environment, work is safe, reliable and stable, the function of replacing a supply lead is achieved, and maintenance is convenient.
Description
Technical field
The present invention relates to explosion-proof solenoid valve technical field, it is specifically related to a kind of novel electromagnetic valve of explosion isolation for coal mine environment.
Background technology
Electromagnetic valve of explosion isolation is that the parts that equipment may be lighted explosive gas mixture are all enclosed in a shell, its shell can bear by any junction surface of shell or structure interval, the flammable mixtures penetrating into enclosure is not damaged at internal explosion, and lighting of the outside explosive atmosphere formed by a kind of, multiple gases or steam can not be caused, the component that may produce spark, electric arc and dangerous temperature are all put into flameproof enclosure, and flameproof enclosure makes the environment of device interior space and surrounding separate.
The electrical installation of colliery and inflammable gas and steam ambient anti-explosion diesel engine should meet the requirement of GB3836.1-2010, and under this standard, general solenoid valve cannot meet. Existing market upper air shut-off valve or the flame-out pull bar of throttle all pass through Air Valve Control, it is necessary to have gas source just can realize the protection function of diesel engine.
The electro-magnet stroke of the existing IIBT4 of meeting explosion-proof criteria is too short or thrust is not enough to make air inlet shut-off valve, throttle to stop working backward stick action. The power supply lead-in wire of electromagnetic valve of explosion isolation is directly connected on coil assembly at present simultaneously, draws from product upper end, and the length of supply lead, from product is made, just cannot change, cumbersome.
For this reason, it is necessary to develop the new explosion-proof type magnetic valve that can be adapted to this stringent environmental.
Summary of the invention
Technical problem to be solved by this invention is the deficiency for above-mentioned existence, there is provided a kind of for colliery and inflammable gas and steam ambient, it is possible to reach every quick-fried effect, safe and reliable stable, and possess replaceable power supply lead-in wire function, the novel electromagnetic valve of explosion isolation of convenient for maintaining.
The technical solution adopted for the present invention to solve the technical problems is:
Novel electromagnetic valve of explosion isolation, adopts external 12V Power supply, it is characterised in that: it is provided with iron core housing and the solenoid housing of cylindrical cavity in comprising, both are coaxially spliced into entirety, and is provided with every plate bursting in the middle of both, is being provided with through hole in the middle of plate bursting; Described solenoid housing is enclosed with iron core built with coil assembly, coil assembly, and iron core is activity structure through through hole, and is wound with return spring outside iron core, and iron core end is connected with connection guide rod, and connection guide rod penetrates out iron core housing and extends to outside; Described coil assembly afterbody is connected with protector, and protector is connected with cable, and the penetration site place of cable and solenoid housing is provided with a down-lead device locking latches, and this device can by cable locking and dismounting.
In such scheme, described down-lead device locking latches is tube-in-tube structure, include permanent seat, coaxial sleeve and briquetting, wherein it is provided with threaded hole in the middle of permanent seat, sleeve holds out against briquetting and is jointly installed in threaded hole, being provided with for the hole that cable passes in the middle of sleeve and briquetting, be provided with sealing-ring between briquetting and permanent seat, its middle sleeve peripheral hardware has spirane structure to screw to be installed in threaded hole.
In such scheme, described is bolted between plate bursting and iron core housing, and is provided with buffer structure on bolt, and this buffer structure is one layer of flat pad and one layer of spring pad.
The principle of the present invention is, adopts 12V Power supply, and under switch-on regime, movable core overcomes the elastic force of return spring, regains and keep recovery state under the magnetic force of electro-magnet, and drive simultaneously is died, oil cutting-off device work; During power-off, electro-magnet magnetic force disappears, and movable core ejects under the elastic force of return spring, and drive is died, oil cutting-off device resets.
The useful effect of the present invention is:
For colliery and inflammable gas and steam ambient, it is possible to reach every quick-fried effect, safe and reliable stable, and possess replaceable power supply lead-in wire function, convenient for maintaining.
