Abstract

The utility model relates to a novel solenoid valve membrane comprising a circular type smooth membrane surface, wherein the membrane surface has two membrane pores which are membrane pore A and membrane pore B, and the centre of the membrane surface has a dummy club which is embossed upwards; a cylindrical cavity which is used for clamping a pallet is arranged between the lower part of the dummy club and the membrane surface; the centre of the dummy club has a central through hole; the two sides of the membrane surface have membrane wings; the membrane wings and the membrane surface are integrated, and the sides of the membrane wings are provided with circular membrane edges. The novel solenoid valve membrane provided by the utility model has the advantages of simple and logic structure, small volume, light weight and convenient application and etc.; furthermore, the service life of solenoid valve can be improved effectively.

Description

A kind of electromagnet valve film

Technical field

The utility model relates to the solenoid valve technical field, is specifically related to a kind of electromagnet valve film.

Background technique

Solenoid valve is the automatic controller that is used for controlling fluid.The working principle of solenoid valve: solenoid valve is made up of Electromagnetic Control body, iron core, spring, diaphragm, pallet, valve body, seat, glue head.During work, the energising of Electromagnetic Control body produces magnetic field, and work is opened in the adhesive of control iron core, and outage separates closes, and quits work.Diaphragm in the solenoid valve is a critical component, directly has influence on magnetic valve performance.Existing solenoid valve is installed together because of diaphragm and pallet, through hole in the middle of the pallet directly and the glue head contact-impact on the iron core, in the long-term adhesive of solenoid valve, work, outage separate, make distortion of glue head or breakage on the iron core, so that appearance is closed incessantly or the pass is not dead, increased the rate of fault of solenoid valve, shortened working life, this is that the glue head is soft plastic cement because the through hole in the middle of the pallet is point or flat, and pallet is hard plastics.

Summary of the invention

The purpose of this utility model is to provide a kind of domestic sewage ecologically treating system, it have simple and reasonable, volume is little, advantage such as in light weight, easy to use, can effectively improve the operating life of solenoid valve.

For achieving the above object, the solution that the utility model is taked is: a kind of electromagnet valve film, it has round smooth face, and two fenestras are arranged in the face, i.e. fenestra A and fenestra B, what raise up in the middle of the face is boss, be the cylindrical cavity that is used for the clamping pallet between boss bottom and the face, the centre of boss is a through hole in, and the both sides of face are the film wings, the film wing and face are one, are shaped on circular film limit on the limit of the film wing.

The middle through hole of diaphragm has replaced the through hole at pallet center, make diaphragm perfect more with combining of pallet, thereby the varying stress that significantly reduced the adhesive of solenoid valve iron core, is produced when separating is to the wearing and tearing of iron core gluing head, can effectively avoid the broken invalid of iron core gluing head, improve the quality, strengthen the reliability that solenoid valve uses the working life of prolongation glue head, avoided the phenomenon that the solenoid valve pass does not live or the pass is not dead occurring because of the distortion or the broken invalid of glue head.

Description of drawings

Fig. 1 is the structural representation of present embodiment.

Among the figure: 1, the film wing, 2, face, 3, fenestra A, 4, fenestra B, 5, boss, 6, middle through hole, 7, cylindrical cavity.

Embodiment

Below in conjunction with embodiment and accompanying drawing thereof the utility model is remake description.

Referring to Fig. 1, a kind of electromagnet valve film, it has round smooth face 2, and two fenestras are arranged in the face 2, i.e. fenestra A3 and fenestra B4, what raise up in the middle of the face 2 is boss 5, be the cylindrical cavity 7 that is used for the clamping pallet between boss 5 bottoms and the face 2, the centre of boss 5 is through holes 6 in, and the both sides of face 2 are film wings 1, the film wing 1 is one with face 2, is shaped on circular film limit on the limit of the film wing 1.

Need to prove that those skilled in the art do not need the various distortion that creative work just can make or revise the protection domain that still belongs to this patent in the scope of tax claim.

Claims
