Description

A kind of electromagnetic exhaust valve

Technical field

The utility model relates to electromagnetic gas valve, especially a kind of electromagnetic exhaust valve.

Background technique

Electromagnetic exhaust valve is controlling component conventional in gas circuit, on 01 19th, 2011 disclose a patent No. is ZL201020295705.8, name is called the utility model patent of " electromagnetic air releasing valve ", it comprises housing, coil holder, coil, magnetisable suction tude, magnetisable movable valve plug, sealing block, spring, coil is on coil holder, coil holder is stuck on housing, coil holder has a central through bore, a cross is arranged at the bottom of central through bore, magnetisable movable valve plug is contained in coil holder central through bore bottom, above cross, sealing block is fixed on magnetisable spool front end, under magnetisable suction tude, part matches with coil holder central through bore top through housing, spring is against between the end face and magnetisable movable valve plug front-end face of magnetisable suction tude bottom, a plug is equipped with in the bottom of coil holder, two pins of plug and the two ends of coil are connected.When this structure electromagnetic air releasing valve assembling, can only first movable valve plug, sealing block, spring be packed in coil holder central through bore, then just can make suction tude bottom and coil holder central through bore top tabling, if because of spring or movable valve plug is stuck need to dismantle time, will extract suction tude, just can pull down spring, movable valve plug, due to suction tude bottom and coil holder central through bore top mixing ratio tightr, extracting of suction tude is more difficult, has affected maintainability.

Model utility content

The technical problems to be solved in the utility model is to provide a kind of electromagnetic exhaust valve, and moving iron core easy accessibility, maintainability are good.

For achieving the above object, the technical solution of the utility model is: a kind of electromagnetic exhaust valve, comprise the coil holder with central through bore, the outer circumferential face of coil holder is wound with coil, and the arranged outside of coil has yoke, and yoke is fixed on coil holder, the bottom of one outlet pipe embeds the top of coil holder central through bore, moving iron core is equipped with in the centre of coil holder central through bore, and the upper end of moving iron core is fixed with vent plug and matches with outlet pipe, between moving iron core and outlet pipe, stage clip is housed; The lower end that coil holder central through bore is stretched out in the bottom of moving iron core, the lower end surface of moving iron core is blocked in coil holder lower end surface to two barbs of downward-extension, the both sides of certain iron plate and yoke fix and lean against the lower end surface of coil holder, the centre of determining iron plate is provided with resigning hole, and the bottom of described two barb cards and moving iron core is through described resigning hole.

Further improve, the upper end of described moving iron core is provided with groove, and the bottom of vent plug is embedded in described groove.Facilitate vent plug and moving iron core to fix.

Further improve, the upper end of described vent plug is provided with an inclined-plane and matches with the lower end of outlet pipe.Can better control the effect of exhaust.

Preferred described vent plug is made up of colloidal silica.

Preferred described outlet pipe is made up of ferrous material.

Further improve, described both sides of determining iron plate are provided with two projections and yoke tabling.

Further improve, two projections of described coil holder lower end surface one side direction downward-extension, two projections are provided with the top tabling of shrinkage pool and two stitch, and two stitch are connected with the two ends of coil.The coil of convenient electromagnetic outlet valve is connected with external power.

The utility model is because the lower end surface of moving iron core is to be stuck on two barbs of coil holder lower end surface, during as the moving iron core of needs dismounting, do not need to extract outlet pipe, just can take out moving iron core, vent plug and spring as long as slightly break two barbs of coil holder lower end surface into two with one's hands, need to reload iron core, vent plug and spring time, two barbs can slightly breaking equally coil holder lower end surface into two with one's hands just can assemble, its easy accessibility, and maintainability is better; On the other hand, because two barbs are to downward-extension, can extend the shift motion of moving iron core, be conducive to strengthen the space between vent plug upper end and outlet pipe lower end, be beneficial to improve exhaust velocity.

Embodiment

Below in conjunction with accompanying drawing and concrete mode of execution, the utility model is described in further detail.

Shown in Fig. 1 to Fig. 8, a kind of electromagnetic exhaust valve, comprise the coil holder 1 with central through bore 11, coil holder 1 is made up of plastic material, the outer circumferential face of coil holder 1 is wound with coil 2, the arranged outside of coil 2 has yoke 3, yoke 3 is fixed on coil holder 1, the bottom of one outlet pipe 4 embeds the top of coil holder 1 central through bore 11, moving iron core 5 is equipped with in the centre of coil holder 1 central through bore 11, and the upper end of moving iron core 5 is fixed with vent plug 6 and matches with outlet pipe 4, and the upper end of moving iron core 5 is provided with groove 51, the bottom of vent plug 6 is embedded in 51 li of described grooves

Between moving iron core 5 and outlet pipe 4, stage clip 7 is housed; The lower end that coil holder 1 central through bore 11 is stretched out in the bottom of moving iron core 5, the lower end surface of moving iron core 5 is blocked in coil holder 1 lower end surface to two barbs 12 of downward-extension, the both sides of certain iron plate 8 are provided with two projections 81 and yoke 3 tablings and lean against the lower end surface of coil holder 1, the centre of determining iron plate 8 is provided with resigning hole 82, and the bottom of described two barb cards 12 and moving iron core 5 is through described resigning hole 82.
