Therefore, the tightness between the movable iron core and the sealing rubber gasket is good, and the service life is prolonged.
Description
The utility model relates to the technical field of electromagnetic gas valve.
Electromagnetic gas valve structure of the prior art mainly is made up of valve body 1, moving iron core 2, coil 3 and power lead 4 shown in Fig. 3,4.Have a circular hole 11 on the valve body 1, these circular hole 11 inner ends communicate with two pores 12,13, and the port of one of them pore 12 also protrudes and forms frustum 14, and these circular hole 11 outer ends stretch out and form a hollow circuit cylinder molded cannula 16; Sleeve pipe 16 outer ends are provided with cock body 17, and moving iron core 2 cooperates springs 21 to be set in the sleeve pipe 16, and moving iron core 2 is provided with seal rubber pad 15, and 3 of coils are nested with on sleeve pipe 16, and coil housing 31 is screwed with valve body 1, makes coil 3 location.
When being used in combination, normal conditions (energising) because spring 21 elastic force effects promote seal rubber pad 15 contact frustums 14 on the moving iron core 2, make between the table top of seal rubber pad 15 and frustum 14 and remain tight the contact, make pore 12 be in normally off; If energising, hot-wire coil 3 produces magnetic field, and moving iron core 2 is done horizontal rectilinear motion in sleeve pipe 16 under the effect of the magnetic line of force, moving iron core 2 pressure springs 21, and seal rubber pad 15 makes pore 12 be in opening state away from frustum 14.
The electromagnetic gas valve of said structure has following disappearance:
1, this electromagnetic gas valve is to remain tight the contact by seal rubber pad 15 with the table top of frustum 14, realizes that pore 12 closes, and for face contacts, seal is relatively poor between the end face of moving iron core 2 and the seal rubber pad 15; And because of the pushing and pressing of moving iron core 2 generally, make the seal rubber pad 15 and the table top of frustum 14 be in the contact state for a long time, time one length very easily causes seal rubber pad 15 to be extruded distortion, makes shorten working life.
2, coil 3 is to be screwed by coil housing 31 and valve body 1 to be positioned in the sleeve pipe 16, and each accessory place's seal that matches is poor, makes the 3 easy oxidations of exposed coil, is corroded, thereby influence the performance of electromagnetic gas valve, also makes the shortening in working life.
3, moving iron core 2 is to be set in the sleeve pipe 16, and 3 of coils are nested with on sleeve pipe 16, and promptly coil 3 need hold sleeve pipe 16 and moving iron core 2 simultaneously, so the volume of coil 3 is big, the volume of whole electromagnetic gas valve is also big, the cost height.When coil 3 energisings, moving iron core 2 and sleeve pipe 16 all are in the electromagnetic field that hot-wire coil 3 produced, because the thickness of pipe wall of sleeve pipe 16, its demagnetizing action is strong, make moving iron core 2 suffered active forces reduce, if will guarantee that moving iron core 2 suffered active forces are enough big, then must strengthen electrical current, this burns out coil 3 easily and can not work long hours.
Main purpose of the present utility model is to provide a kind of electromagnetic gas valve, makes the good leak tightness between iron core and the seal rubber pad, and increase working life.
Secondary objective of the present utility model is to provide a kind of electromagnetic gas valve, makes each accessory place's good leak tightness that matches, and coil is difficult for oxidation, is corroded, and increase working life.
Another purpose of the present utility model is to provide a kind of electromagnetic gas valve, makes whole electromagnetic gas valve volume-diminished, and cost reduces; And the coil electricity electric current reduces, easy burn-out not, but and long period work.
For reaching above-mentioned purpose, solution of the present utility model is:
Electromagnetic gas valve mainly is made up of valve body, moving iron core, coil and power lead.Have a circular hole on the valve body, this circular hole inner end communicates with two pores, and the port of one of them pore is provided with seal rubber pad, and the hollow circuit cylinder molded cannula that is provided with an outer end sealing is extended in this circular hole outer end; Moving iron core cooperates spring to be set in the sleeve pipe, and moving iron core is tight with seal rubber pad and contacts, and coil then is nested with on sleeve pipe, and coil housing and valve body are fixed, and wherein, move iron core and the contacted end of seal rubber pad and are cone shape.
Above-mentioned valve body and sleeve pipe are two members, and sleeve pipe is fixedly connected on the circular hole outer end, and circular hole outer end and sleeve pipe joint are provided with seal ring.
The outer end of above-mentioned sleeve pipe fixedly plugs a cock body, and forms the outer end of sealing, and sleeve pipe is provided with seal ring with the cock body place of matching.
Above-mentioned coil housing is injection-moulded in the coil integrated type, and integrated coil is by on the cock body in the screw sleeve pipe.
After adopting said structure, the utlity model has following advantage:
1, the moving iron core of the utility model is cone shape with the contacted end of seal rubber pad, makes it to be contacted with face between the seal rubber pad by the end face of moving iron core to change the end face that moves iron core into and contact with line between the seal rubber pad, and seal is good; And because of seal rubber pad is set directly at the port of pore, do not exist and the long-term contact of the table top of frustum, so the anxiety of no extrusion-deformation, increase working life.
2, the utility model coil is injection-moulded in the coil housing integrated type, and coil is closely being coated by coil housing fully, can oxidation, corrosion, thus making the stable performance of electromagnetic gas valve, increase working life.
3, the utility model valve body and sleeve pipe are two members, it is the independent moulding of sleeve pipe, can be made into thin wall casing, has thicker tube wall in the product of commonly using the integrated sleeve pipe and needn't resemble, the winding volume that holds sleeve pipe and moving iron core is reduced, the volume of whole electromagnetic gas valve also reduces, and cost reduces.Simultaneously, because the tube wall of sleeve pipe is thin, a little less than its demagnetizing action, make the moving suffered active force of iron core increase relatively, the coil electricity electric current is reduced relatively, and coil can be switched on for a long time and do not burnt out.
In a word, the utlity model has good sealing effect, long service life, volume is little, and the advantage that cost is low mainly can be used for the control of various single effect cylinders, air horn, diaphragm valve clutch, break etc. and the switching and the program control of high low pressure.
