Description
The utility model is about valve, and in particular, the utility model is about the electric control permanent magnet valve.
Known electromagnetic air valve is made of electromagnetic coil, electromagnet, valve body, spool, air chamber, supporting plate, spring etc. at present.This valve is according to the differential principle design of secondary.When electromagnetic coil switching electric current, electromagnet open and close valve moves up and down spool in valve body, changes gas circuit, thereby finishes the control function of valve.This valve is the process structure complexity not only, and the long-time energising of electromagnetic coil burns easily, and in addition, energy consumption is big.
The purpose of this utility model be overcome in the prior art not enough, provide a kind of energy-conservation, process structure is simple, safe and reliable, volume is little, lightweight device.
The utility model is achieved by following technical proposals:
Magnetic shielding cover ［ 1 ］ places on the supporting plate ［ 4 ］, be arranged with sealing gasket ［ 5 ］ and ［ 10 ］ on the spool ［ 6 ］, spool ［ 6 ］ has inlet hole ［ 11 ］, air outlet hole ［ 8 ］, exhaust port ［ 14 ］, air chamber ［ 15 ］ is set in the valve body ［ 7 ］, spool ［ 7 ］ has inlet hole ［ 12 ］, air outlet hole ［ 9 ］, exhaust port ［ 13 ］, valve body ［ 7 ］ top is provided with electromagnetic stator ［ 2 ］ up and down, permanent magnetism mover ［ 3 ］ is set between them, last Circuit breaker ［ 20 ］, following Circuit breaker ［ 18 ］, stage clip ［ 19 ］, spool ［ 6 ］ is connected with permanent magnetism mover ［ 3 ］, and buffering secondary spring ［ 17 ］ is set between electromagnetic stator ［ 2 ］ and the spool ［ 6 ］.
Described electromagnetic stator ［ 2 ］ constitutes by two-wire and around two groups of electromagnetism windings ［ 25 ］, ［ 26 ］ and ［ 27 ］, ［ 28 ］ of reversal connection in twos.Described permanent magnetism mover ［ 3 ］ superpower permanet magnetic material.Described spool ［ 6 ］ adopts shouldered structure.Described spool exhaust port ［ 14 ］ adopts loop configuration.
The utility model will be further described below in conjunction with accompanying drawing.
Fig. 1 is a structural drawing of the present utility model;
Fig. 2 is an automatically controlled schematic representation of the present utility model.
In the drawings, magnetic shielding cover ［ 1 ］ is made by diamagnetic material, and valve body ［ 7 ］ is made by low carbon steel.Utilize retaining screw ［ 16 ］ that radome ［ 1 ］ is connected with valve body ［ 7 ］.Electromagnetic stator ［ 2 ］ is made of electromagnetic coil, soft magnet core and skeleton.Last electromagnetic stator is screwed on magnetic shielding cover, and following electromagnetic stator ［ 2 ］ is fixed on the supporting plate of being made by diamagnetic material ［ 4 ］, and permanent magnetism mover ［ 3 ］ is made by high strong permanent magnet material, for example Nd Fe B alloys.Permanent magnetism mover ［ 3 ］ upper and lower surface is stained with the magnetic conduction rubber cushion, and it is connected with the spool ［ 6 ］ that diamagnetic material is made.Valve body ［ 7 ］ and spool ［ 6 ］ are provided with inlet hole, air outlet hole and exhaust port respectively.Sealing gasket ［ 5 ］ and ［ 10 ］ are made by rubber, seal in the valve switch process.For making valve stress balance when the switch, buffering secondary spring ［ 17 ］ is set between supporting plate ［ 4 ］ and spool ［ 6 ］.Last Circuit breaker ［ 20 ］ connects winding ［ 25 ］ and ［ 26 ］ respectively, and following Circuit breaker ［ 18 ］ connects winding ［ 27 ］ and ［ 28 ］ respectively.Winding ［ 25 ］ connects delay switch normal opened contact ［ 23 ］ and break contact ［ 24 ］ all connects condition relay ［ 22 ］, and condition relay ［ 22 ］ connects commands relays ［ 21 ］.
When commands relays ［ 21 ］, condition relay ［ 22 ］, time delay relay normally opened contact ［ 23 ］ and normally-closed contact ［ 24 ］ start, electric current is just connecing electromagnetism winding ［ 25 ］ by last electromagnetic stator ［ 2 ］, during following electromagnetic stator ［ 2 ］ reversal connection electromagnetism winding ［ 26 ］, permanent magnetism mover ［ 3 ］ drives spool ［ 6 ］ and moves up under bidirectional magnetic force promotes, spool exhaust port ［ 14 ］ is sealed, high-pressure air enters spool ［ 6 ］ through air chamber ［ 15 ］, flows to valve body air outlet hole ［ 9 ］ and enters braking device.In the moment that permanent magnetism mover ［ 3 ］ moves up, Circuit breaker ［ 20 ］ in stage clip ［ 19 ］ triggering is cut off the electricity supply.The suction-combining force by permanent magnetism mover ［ 3 ］ is positioned on the stator iron core, and valve is in stable opening state.
Because time delay relay normal opened contact ［ 23 ］ and instruction relay ［ 21 ］ is contacted mutually, when brake finishes, time delay relay normally opened contact ［ 23 ］, normally-closed contact ［ 24 ］ action, normal opened contact ［ 23 ］ is opened, connect break contact ［ 24 ］ simultaneously, electric current is by last electromagnetic stator ［ 2 ］ reversal connection electromagnetism winding ［ 26 ］, following electromagnetic stator ［ 2 ］ is just connecing electromagnetism winding ［ 28 ］, permanent magnetism mover ［ 3 ］ is under bidirectional magnetic force promotes, driving spool ［ 6 ］ by buffering secondary spring ［ 17 ］ moves down, rapid throttle down, spool exhaust port this moment ［ 14 ］ is opened, and residual gas is discharged through this hole.By the suction-combining force and the effect that cushions secondary spring ［ 17 ］ of permanent magnetism mover ［ 3 ］, valve closing is firm closely.
The utility model compared with prior art has following good effect:
1, safe and reliable, coil is difficult for burning, and the life-span is long.
2, energy-conservation, power consumption is little.
3, volume is little, and is in light weight, and cost is low.
4, manufacturing process is simple.
