Abstract
The utility model relates to a direct-action electromagnetic valve, which is mainly composed of a valve body, a seal head, a coil, a return spring, core iron, etc. The seal end of the core iron is provided with a soft sealing plug made of teflon; the sealing of the valve port is realized through the soft sealing plug, therefore, the utility model has the advantages of simple structure, good tightness, excellent sealing performance, long-term stabilization, the advantage that the composite cost of the valve is reduced, etc. The implement of the utility model can thoroughly solve the phenomena that the refrigeration system can not closed, the defrosting effect is not good while in the defrosting run-time, etc.
Description
The utility model relates to a kind of small-sized direct action solenoid valve, especially a kind of small-sized direct action solenoid valve that has novel sealing structure.
What small-sized direct action solenoid valve of the prior art generally adopted at home is hard sealing structure, as the steel ball sealing structure, such solenoid valve is to valve port requirement on machining accuracy height, and requirement degree of finish, the steel ball with high precision that circularity is all good, this just realizes producing in enormous quantities to this valve and has brought certain degree of difficulty.
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and it is low to improve a kind of manufacturing processing request, the direct action solenoid valve that sealability is good and long-term work is reliable and stable.
The purpose of this utility model is finished by following technical solution, and it is to make hard sealing structure into soft sealing structure, and promptly the sealed bottom at core iron is provided with the soft seal plug.
Described soft seal plug is made by polytetrafluoroethylplastic plastic, and its sealing surface is concordant.
Accompanying drawing is a structural representation of the present utility model.
To be described in detail the utility model by accompanying drawing below: the utility model mainly is made up of valve body 1, end socket 2, coil 3, returning spring 4, core iron 5.The top of valve body 1 is fixed with coil 3 by end socket 2, is mounted with core iron 5 in the valve body 1, and the epimere roof pressure of this core iron 5 has a returning spring 4, and is provided with the soft seal plug of forming with polytetrafluoroethylplastic plastic 6 at the sealed bottom of core iron 5.On valve body, also be connected to entrance sleeve 7 and discharge connection 8.
The utility model in use, when coil 3 energisings, the electromagnetic force of its generation overcomes pretightening force, core iron 5 deadweights of returning spring 4 and acts on the fluid pressure difference power of sealing plug 6 and valve body 1 sealing valve port face, at this moment core iron is sucted, valve port is opened, this moment, flowing medium flowed to discharge connection 8 from entrance sleeve 7 through valve port rapidly, and valve is on state.When coil losing electricity, core iron 5 is subjected to the effect of returning spring 4 restoring forces and falls, valve port is closed, and the difference force acting in conjunction that forms in returning spring 4 power, core iron 5 deadweights and import and export adapter pressure drop on the sealing surface is issued to closes seal action, and this moment, valve was in closed condition.
The utility model is owing to adopt soft sealing structure, have simple in structure, good seal performance, sealing property is excellent Different and steady in a long-term, can reduce the integrated cost of valve, can thoroughly solve refrigeration system close not dead, the defrost operation The characteristics such as the Shi Huashuan effect is bad.
