Abstract
The utility model relates to a diaphragm-typed electromagnetic valve which is composed of a valve body, an electromagnetic head part, a sealing ring, a spring, a plastic sealing shim, an auxiliary valve hole, a ring spacing gasket, core iron, etc. The plastic sealing shim and the auxiliary valve hole are adopted to substitute an original copper slide block (piston) to control the on-off of the liquid in the refrigeration system pipes. The plastic sealing shim and the auxiliary valve hole are combined together by pressing. The utility model has the advantages of reasonable structure, flexible action, high valve opening ability, small size, light weight, copper saving, and low cost. The utility model has stronger competitive power among the similar products.
Description
The utility model relates to a kind of solenoid valve, particularly a kind of diaphragm electromagnetic valve.
Solenoid valve can be serially connected in the pipeline of refrigeration system, and the electrical equipment command signal that sends according to pressure controller and temperature controller etc. moves, with the on-off of fluid in the control system pipeline.At present domestic solenoid valve is because valve body structure adopts slide block (piston) seal form, and slide block adopts the copper material manufacturing, make to exist valve volume big, and Heavy Weight, it is many to expend copper material, cost height, shortcoming such as processing difficulties, profile are attractive in appearance inadequately.
The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and provides a kind of employing plastic seal pad (diaphragm) and auxiliary valve opening to replace copper slide block, and in light weight, and volume is little, the diaphragm electromagnetic valve that is active in one's movements.
The purpose of this utility model can reach by following measure: the utility model comprises valve body, Electrical heads parts, seal ring, spring, it is characterized in that: also have gasket seal, auxiliary valve opening, annular stop packing ring, core iron, gasket seal and auxiliary valve opening press together, inlet channel and outlet passage on the valve body are communicated with by valve opening, be with the annular stop packing ring on the valve opening, its aperture is pushed down by gasket seal and auxiliary valve opening, auxiliary valve opening is pushed down by core iron again, forms a cavity between gasket seal, auxiliary valve opening and iron core.The annular stop packing ring causes a pot shape, equidistant several circular holes that has on it, and gasket seal adopts the tetrafluoroethylene manufacturing, and symmetry has two small sircle holes on it.
Fig. 1 is a structure sectional view of the present utility model;
Fig. 2 is the structural representation of gasket seal 5 and auxiliary valve opening 6;
Fig. 3 is the structural representation of annular stop packing ring 7.
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
With reference to Fig. 1, Fig. 2, Fig. 3, the utility model is made up of valve body 1, Electrical heads parts 2, seal ring 3, spring 4, gasket seal 5, auxiliary valve opening 6, annular stop packing ring 7, iron core 8 etc.
During work, the working medium in the refrigeration pipe enters from inlet channel 9, slowly enters cavity 14 by the small sircle hole 13 in circular hole in the annular stop packing ring 7 12 and the gasket seal 5, makes it be full of working medium.At this moment, pushed down by iron core 8, be communicated with outlet passage 10) so working medium can not flow to outlet passage 10(valve opening 11 by valve opening 11 because of auxiliary valve opening 6.When Electrical heads parts 2 are connected power supply, core iron 7 is opened by the auxiliary valve opening 6 of adhesive (moving upward), working medium in the cavity 14 flows into outlet passage 10 from auxiliary valve opening 6 by valve opening 11, at this moment on gasket seal 5 and the auxiliary valve opening 6, form pressure difference between cavity of resorption, cavity of resorption (valve opening 11) increases because of flowing into working medium event pressure, and epicoele (cavity 14) reduces because of flowing out working medium pressure, event cavity pressure down is higher than upper cavity pressure, gasket seal 5 is upwards backed down, open valve opening 11, the working medium that flows into from inlet channel 9 just directly flows to outlet passage 10 by valve opening 11, and like this, the working medium in the refrigeration system pipeline is just negotiable.When Electrical heads parts 2 dead electricity, core iron 7 is released, and by the effect of spring 4 it is resetted, and pushes down auxiliary valve opening 6 again, and presses position valve opening 11 again with the gasket seal 5 that auxiliary valve opening 6 presses together, and recovers original state.
The utility model has following advantage compared to existing technology:
1. volume is little, and is in light weight, and cost is low, saved a large amount of copper materials, and reduced difficulty of processing.
2. rational in infrastructure, be active in one's movements, it is big to open the valve ability, has stronger competitive ability in like product.
Claims (2)
1, a kind of diaphragm electromagnetic valve, comprise valve body 1, Electrical heads parts 2, seal ring 3, spring 4, it is characterized in that: also have gasket seal 5, auxiliary valve opening 6, annular stop packing ring 7, core iron 8, gasket seal 5 and auxiliary valve opening 6 press together, inlet channel 9 on the valve body 1 and outlet passage 10 are communicated with by valve opening 11, be with annular stop packing ring 7 on the valve opening 11, its aperture is pushed down by gasket seal 5 and auxiliary valve opening 6, auxiliary valve opening 6 is pushed down by core iron 8 again, forms a cavity 14 between gasket seal 5, auxiliary valve opening 6 and iron core 8.
2, solenoid valve according to claim 1 is characterized in that: the annular stop packing ring causes a pot shape, equidistant several circular holes 12 that has on it, and gasket seal 5 adopts the tetrafluoroethylene manufacturing, and symmetry has two small sircle holes 13 on it.
