Abstract
The invention relates to an electromagnetic valve body, which comprises an inlet pipe, an outlet pipe and a sealed chamber, wherein the sealed chamber is provided with a sealing device; the inlet pipe is provided with a downward blow-off pipe; the tail end of the blow-off pipe is provided with a seal plug; a seal ring is fixed on the inner side of the seal plug; and the inner wall of the blow-off pipe and the inner wall of the inlet pipe are provided with a communicated strainer groove. The electromagnetic valve body is characterized in that: a strainer is arranged in the strainer groove and an elastic seal washer I is arranged between the strainer and the strainer groove. The sealing property between the strainer and the strainer groove is enhanced, water with impurities cannot enter the sealing device, and the service life of the sealing device is not influenced.
Description
Technical field
The present invention relates to a kind of solenoid valve, relate in particular to a kind of electromagnetic valve body.
Background technique
Spool in the seal arrangement of solenoid valve is easy to cause killing because of impurity now, in particular for solenoid valve waterborne.To this common way is to establish a filtrating equipment in inlet pipes, as Chinese patent, the patent No. is 200620113433.9, specification discloses a kind of " electromagnetic valve body ", this electromagnetic valve body is provided with filter screen in drain pipe He in the inlet tube, this filter screen can filter the impurity in the water effectively, but the sealing of this filter screen and drain pipe and inlet tube inwall is relatively poor, the water that has impurity that has part in the using process can enter in the seal arrangement between filter screen and filter screen groove, reduces the working life of solenoid valve.
Summary of the invention
The purpose of this invention is to provide the good electromagnetic valve body of a kind of strainability.
The technical solution used in the present invention is:
A kind of electromagnetic valve body, comprise inlet tube, outer pipe and closed chamber, described closed chamber is provided with seal arrangement, described inlet tube is provided with downward drain pipe, the end of this drain pipe is provided with sealing plug, and the inboard of sealing plug is fixed with seal ring, on the inwall of described drain pipe and the inwall of inlet tube be provided with the filter screen groove that is connected, be provided with filter screen in the described filter screen groove, be provided with elastic packing packing ring I between described filter screen and the filter screen groove.
Further, described sealing plug and filter screen groove corresponding section have fixed groove, are provided with elastic packing packing ring II in this fixed groove.
Further, the diameter of described filter screen mesh is 0.05-0.8mm.
The present invention between filter screen and filter screen groove cushioning elastic packing packing ring I, strengthened the sealing between filter screen and the filter screen groove, guaranteed that the water that has impurity can not enter in the seal arrangement, influences the working life of seal arrangement.For the sealing between further enhanced leaktightness plug and the filter screen, established fixed groove at sealing plug and filter screen groove corresponding section, in fixed groove, be provided with elastic packing packing ring II.
