Can be found out that by Fig. 1～3 said impulse electromagnetic valve comprises that said impulse electromagnetic valve comprises valve component and electromagnetic assembly, said electromagnetic assembly is fixedly mounted in the front of said valve component.Said valve component comprises valve body 210, four jiaos of screw threads 211 of spool, spool rubber cushion 212, spool gland 213, filter screen 214, spool 215, spool diaphragm 216, big spring 217, O type circle 218 and regulates copper lid 219.Said electromagnetic assembly comprises plastics 320, diaphragm 321, disk 322, band needle spring 323, O type circle 324, valve gap 325, liner 326, moving iron core 327, coil spring 328, O type circle 329, lower support frame 330, O type circle 331, coil 332, static iron core 333, O type circle 334, rubber pad 335, magnet 336, coil case 337.

When assembling said impulse electromagnetic valve; At first assemble piston body 1; Spool diaphragm 216 is enclosed within on the spool 215; Below spool 215, put into filter screen 214, spool gland 213 and spool rubber cushion 212 successively, spool rubber cushion 212, spool gland 213, filter screen 214 and spool 215 are securely connected to constitute piston body through four jiaos of screw threads 211 of spool.

When assembling valve body subsequently; Said piston body is placed in the inner chamber of valve body 210; On said spool 215, place a big spring 217 regularly and regulate copper lid 219, regulate copper and cover 219 belows and be with O type circle 218, regulate copper lid 219 and valve body 210 and be fixedly connected through screw thread.

Assembling is during coil, and waterproof plug 37 passes shell, and static iron core 333 puts O type circle 334 and 332 li of the coils of packing into, and rubber pad 335 is placed on the static iron core 333, and magnet 336 is placed in the coil 332, pack into 337 li of coil cases of coil 332.Cover lower support frame 330, riveted, O type circle 329 are enclosed within on the coil of lower support frame outside.The inner chamber of said coil 332 is by the epoxy resin embedding.Valve gap 325 is installed in the plastics 320, and liner 326 is enclosed within on the moving iron core 327, places coil spring 328 to moving iron core 327, and moving iron core is packed in the coil.

During the assembling control valve body; O type circle 324 places in the plastics 320; Diaphragm 321 is enclosed within on the disk 322, and band needle spring 323 is housed on disk 322, and the pin of band needle spring 323 inserts in the pilot hole 341 on the disk 322; Whole disk 322 is arranged on 325 li of valve gaps, is fixed on above the valve gap with nut 340.The valve gap 325 that installs disk 322 is packed in the plastics 20.Plastics 320 is put O type circle 324, and the valve body 210 of packing into is with in the control valve die cavity, puts 332, four key screw coils of complete coil 332 that the front installs and couples together with plastics 320 and copper valve body 210.

Spool adopts the piston structure formula; Pilot hole is opened on piston; Hole big or small easy to control; The built-in filter screen of piston, the water quality that is used to filter pilot hole and control electromagnetic valve on the piston has overcome effectively just as flushing valve and first guide groove has been opened on the main valve chamber inwall and obstruction in use and water appears having nothing to do with in the whole main valve that causes and Guan Shui postpones phenomenons such as shakiness.Control electromagnetic valve adopts a complete impulse electromagnetic valve, controls the open and close of main valve plug (piston).

Spool adopts high-quality engineering plastics, and is in light weight, dimensionally stable.Because it is in light weight, open more easily when hanging down hydraulic pressure in use, thereby improve the flow that main valve hangs down hydraulic pressure.Can reduce simultaneously the friction of spool diaphragm in main valve chamber, the working life of improving main valve plug greatly again.

Coil directly is connected with main valve body through four screws with plastics, is convenient to dismounting and cleans.Because the main valve body material is a brass, increased join strength greatly simultaneously.

Coil is with stainless steel casing and lower support frame parcel, and the coil inner chamber is used the epoxy resin embedding, and coil lead is drawn with waterproof connector, and whole winding forms a strong obturator, so waterproofing effect is remarkable.The pilot hole place has installed special band needle spring additional on the interior disk of solenoid valve water flowing die cavity; Can form the automatic cleaning to pilot hole of band needle spring at every turn when diaphragm moved up and down when solenoid valve opened and closed, effectively prevent pilot hole blocking phenomenon in use.The shell of coil draws high with the high-quality stainless steel and forms, and polishing treatment has been carried out on the surface, has increased beautiful appearance.The solenoid valve lighting outlet adopts waterproof plug, has effectively overcome the oxidation that original ordinary plug in use takes place and causes phenomenon such as plug bad connection.

The stool of the utility model is adopted the piston structure formula towards Xian's solenoid valve, and the opening and closing of solenoid valve move up and down by main valve plug and realize, all can work preferably under the situation of height hydraulic pressure and big flow, and piston is not fragile.Whole valve body forms with brass casting, can bear fully because formed reverse punching press during big die cavity electromagnetic valve switch.

During opens solenoid valve, coil is connected a direct impulse signal that adds direct impulse voltage, and coil produces pulsed magnet field; Its polarity is opposite with permanent magnet polarity, and according to the magnet principle that there is a natural attraction between the sexes, moving iron core moves up; With the absorption of static iron core plane, kept by permanent magnet magnetic force, the pressure release aperture is opened; Valve gap relief hole conducting like this, disk epicoele water is drained, and the disk upper cavity pressure descends rapidly; Thereby form main valve plug (disk) pressure difference (upper cavity pressure is less than following cavity pressure) up and down, disk moves up under the effect of hydraulic pressure, and control partly valve opening solenoid is opened.After control part valve opening solenoid opens; Piston body epicoele water is drained, and the piston body upper cavity pressure descends rapidly, thereby forms main valve plug (piston body) pressure difference (upper cavity pressure is less than following cavity pressure) up and down; Piston body moves up under the effect of hydraulic pressure, and the solenoid valve main valve is opened.

When closing solenoid valve, coil is connected the negative-going pulse signal that adds a negative-going pulse voltage, and coil produces pulsed magnet field; Its polarity is identical with permanent magnet polarity, and according to the principle that the magnet same sex is repelled each other, moving iron core moves down; Kept by spring force; Block bonnet central bore, moving like this iron core ejects, and the valve gap relief hole is blocked; Medium (water) gets into the disk epicoele by the disk pilot hole; The disk upper cavity pressure increases sharply; Upper cavity pressure gos up rapidly and forms main valve plug (disk) pressure difference (upper cavity pressure is greater than following cavity pressure) up and down, and disk moves down under the effect of hydraulic pressure, and control is closed electromagnetic valve partly.Behind the control part closed electromagnetic valve; Medium (water) gets into the piston body epicoele by the cold body pilot hole of living; The piston body upper cavity pressure increases sharply; Upper cavity pressure gos up rapidly and forms main valve plug (piston body) pressure difference (upper cavity pressure is greater than following cavity pressure) up and down, and piston body moves down under the effect of hydraulic pressure, and the solenoid valve main valve is closed.

What need statement is that above-mentioned model utility content and embodiment are intended to prove the practical application of technological scheme that the utility model provides, and should not be construed as the qualification to the utility model protection domain.Those skilled in the art are in the spirit and principle of the utility model, when doing various modifications, being equal to replacement or improvement.The protection domain of the utility model is as the criterion with appended claims.
