Abstract
The utility model discloses a novel electromagnetic valve membrane, which is characterized in that the novel electromagnetic valve membrane comprises an amplitude membrane, an amplitude edge and a boss, wherein the amplitude membrane takes ring shape with middle projected upwards, the bottom edge of the membrane edge is provided with a ring shaped amplitude edge, the middle of the amplitude membrane is provided with the pillar boss which is projected upwards, the inner portion of the boss is provided with the pillar cavity for clamping an iron core, one end of the pillar cavity hole is provided with a cup-shaped card projection. The electromagnetic valve membrane which is provided by the utility model has the advantages of simple and reasonable structure, small bulk, light weight, inexpensive price, convenient use and the like and can ensure the seal effect simultaneously. The membrane greatly reduces deformation stress generated by the membrane when the electromagnetic valve iron core adsorbs, can effectively reduce energy consumption and loss of the electromagnetic valve, improves efficiency and prevents the membrane from mechanically ageing and losing effect, which lengthens the use life of the membrane, reinforces the reliability of the electromagnetic valve and avoids the loss due to ineffectiveness of the electromagnetic valve.
Description
Technical field
The utility model relates to the medical device field, is specifically related to a kind of electromagnet valve film.
Background technique
Solenoid valve is the automation foundation element that is used for controlling fluid or gas, the isolation diaphragm solenoid valve is that valve body and driving part are isolated, it can not only stop fluid, flowing into metallic material is the main drive part of making, in case it is corroded, the metal powder that also can prevent the driving part generation is simultaneously sneaked in the fluid, is widely used in the control of medical apparatus, Biochemical Analyzer and some other corrupt liquid of industry.
The working principle of isolation diaphragm solenoid valve: solenoid valve is made up of electromagnetic coil, iron core, spring, diaphragm, valve body, diaphragm is effectively isolated iron core, spring, coil and valve body, the electromagnetic coil energising produces magnetic field during work, control iron core against the force of the spring pulling diaphragm opens or closes input, delivery outlet.
Diaphragm in the isolation diaphragm solenoid valve is parts that are directly connected to its usability.Existing solenoid valve diaphragm is a dull and stereotyped diaphragm, the electromagnetic coil energising produces magnetic force during work, except that control iron core against the force of the spring, also must overcome the stress that diaphragm deformation is produced, for reaching reliably working, that usually electromagnetic coil power is selected is bigger, and diaphragm tensile buckling repeatedly when work in addition causes the aging acceleration of mechanical property, increase the rate of fault when solenoid valve uses, reduced working life.
Because its etch-proof characteristics of isolation diaphragm solenoid valve, it is widely used in haemodialysis control unit, dialyser multiplexing machine, the Biochemical Analyzer of medical industry at present, and chemical test equipment and industrial trade, but the isolation diaphragm solenoid valve on the market all is to derive from import, and because its flat sheet membrane chip architecture problem, volume and the power often done are bigger, and the diaphragm mechanical deformation is aging, causes problems such as reduction in working life.
The model utility content
The purpose of this utility model is to overcome above-mentioned technical deficiency, a kind of electromagnet valve film is provided, that this solenoid valve diaphragm has is simple and reasonable, the little light weight of volume, advantage such as cheap, easy to use, can effectively improve the working efficiency of solenoid valve, reduce the power of solenoid valve electromagnetic coil, thereby reduced the volume of solenoid valve, simultaneously can also guarantee sealing effect, significantly reduced the ageing failure that causes because of the long-term mechanical deformation of diaphragm, thereby avoided causing damage because of solenoid valve loses efficacy.
For reaching the foregoing invention purpose, the technological scheme that is adopted is: a kind of electromagnet valve film is characterized in that: described electromagnet valve film comprises width of cloth film, breadths and boss; Described width of cloth film is the middle ring that raises up; The bottom margin of described width of cloth film is provided with circular breadths, and the middle part of width of cloth film is provided with the cylindrical boss that raises up; The inside of described boss is provided with the cylindrical cavity that is used for the clamping iron core, and opening one end of cylindrical cavity is provided with ring-type screens projection.
That solenoid valve diaphragm provided by the utility model has is simple and reasonable, the little light weight of volume, advantage such as cheap, easy to use, can effectively improve the working efficiency of solenoid valve, reduce the power of solenoid valve electromagnetic coil, thereby reduced the volume of solenoid valve, simultaneously can also guarantee sealing effect, significantly reduced the ageing failure that causes because of the long-term mechanical deformation of diaphragm, thereby avoided causing damage because of solenoid valve loses efficacy.

Fig. 4 be among Fig. 3 the electromagnet valve film along the sectional structure chart of A-A line.
Wherein, 1, width of cloth film; 2, boss; 3, breadths.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure, a kind of electromagnet valve film comprises width of cloth film 1, breadths 3 and boss 2; Described width of cloth film 1 is the middle upwards ring of protuberance; The bottom margin of described width of cloth film 1 is provided with circular breadths 3, and the middle part of width of cloth film 1 is provided with the cylindrical boss 2 that raises up; The inside of described boss 2 is provided with the cylindrical cavity that is used for the clamping iron core, and opening one end of cylindrical cavity is provided with ring-type screens projection.
In general, solenoid valve comprises electromagnetic valve body, diaphragm, iron core, plastic-sealed body and spring.Described diaphragm is the disc of swelling on the cambered surface, and the diaphragm upper end is provided with the cylindrical cavity that is used for clamping solenoid valve iron core; A described solenoid valve end plastic packaging unshakable in one's determination is in plastic-sealed body, and the other end is connected in the cylindrical cavity of diaphragm upper end.
That this solenoid valve diaphragm has is simple and reasonable, the little light weight of volume, advantage such as cheap, easy to use, simultaneously can also guarantee sealing effect, significantly reduced the ageing failure that causes because of the structure of diaphragm, thereby avoided causing damage because of solenoid valve loses efficacy.
Though described mode of execution of the present utility model in conjunction with the accompanying drawings, the protection domain that those of ordinary skills do not need various distortion that creativity work just can make or modification still to belong to this patent within the scope of the appended claims.
