Abstract
The utility model relates to a structure of a slipper sealing surface for the rotary type solenoid valve, which comprises a slipper matching the magnetic rotor component through the sliding key. The slipper presses the sealing surface of the lower part closely onto the end of the valve seat through the upper spring. The sealing ring with the width larger than the liquid outlet diameter of the valve seat is arranged on the sealing surface of the slipper and the groove and bracing belt are arranged in the middle. Compared with the prior art, the utility model has the advantages of reasonable structure, convenient application and fixation, meanwhile, the utility model can reduce the contact area of the sealing surface, lessen the frictional resistance, improve the sealing performance between the slipper and the valve seat and effectively avoid the occurrence of vacuum suckback.
Description
Technical field
The utility model relates to a kind of slide block sealing surface structure of rotary type solenoid valve, a kind of structure that directly contacts and seal with valve body sealing surface belongs to the parts of solenoid valve.
Background technique
In the prior art, the slide block sealing configuration of rotary type solenoid valve includes the slide block that cooperates by slide key with magnetic rotor component, and slide block tightly is fitted on the end face of valve seat the sealing surface of its underpart by upper springs, thereby plays the effect of sealing.But because slide block and valve seat relatively rotate, be slide block be under magnetic rotor component drives relative to rotating on valve seat top, so can produce bigger surface friction drag each other, very high to each other seal request, it is bad to be easy to generate sealability, and the situation that influences the overall structure performance occurs.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned existence, and provide a kind of valve seal performance that can improve, the reduce friction slide block sealing surface structure of rotary type solenoid valve of resistance, it includes the slide block that cooperates by slide key with magnetic rotor component, this slide block tightly is fitted on the end face of valve seat the sealing surface of its underpart by upper springs, on the sealing surface of slide block, be shaped on the seal band of width, and be shaped on groove therebetween greater than valve seat liquid outlet opening diameter.
Also be shaped on supporting band on the described slide block sealing surface, and supporting band and seal band have constituted the sealing surface of slide block.Described seal band is a circular ring.
The utility model compared with prior art has rational in infrastructurely, easy to install and use, can reduce the area of contact of sealing surface, and the resistance of reducing friction improves the sealability between slide block and the valve seat, can effectively prevent the phenomenon of negative pressure suck-back.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of slide block sealing surface of the present utility model.
Fig. 3 is other structural representation of slide block sealing surface of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in Figure 1, the utility model includes the slide block 2 that cooperates by slide key with magnetic rotor component 1, between magnetic rotor component 1 and the slide block 2 spring 3 is arranged, it is pressed on the upper end of slide block 2, is shaped on two fluid apertures 5 on the end face of valve seat 4.When external coil drives the magnetic rotor component 1 of valve inner, on the end face of valve seat 4, make circular movement along central shaft 6 thereby drive slide block 2, thereby reach the working state that realizes by preset program.
Shown in Figure 2, in order to reduce the area of contact between slide block 2 and the valve seat 4, the resistance of reducing friction, improve sealability, the utility model has dug groove 7 in the middle of the sealing surface of slide block 2, be shaped on the seal band 8 of width greater than the fluid hole diameter on sealing surface, sealing endless belt 8 can play the effect of sealing fully on the one hand, can avoid occurring the phenomenon of negative pressure suck-back on the other hand.In order to make slide block 2 sealing surfaces and valve seat 4 end face stickiness good, the utility model also designs on sealing surface annular brace band 9, to guarantee the stationarity of slide block.For realizing the purpose of sealing, the sealing surface of slide block 2 can have multiple shape and structure, and shown in Figure 2 is the circular ring of certain angle.Other embodiment of the present utility model also includes other shape and structure that can realize this purpose, and is trapezoidal as triangle, rectangle, and circle or Else Rule or irregularly shaped, and its supporting band also has difformity structure correspondingly, sees shown in the accompanying drawing 3.
Claims (3)
1, a kind of slide block sealing surface structure of rotary type solenoid valve, it includes the slide block that cooperates by slide key with magnetic rotor component, this slide block tightly is fitted on the end face of valve seat the sealing surface of its underpart by upper springs, it is characterized in that on the sealing surface of slide block (2), being shaped on the seal band (8) of width, and be shaped on groove (7) therebetween greater than valve seat liquid outlet opening diameter.
2, the slide block sealing surface structure of rotary type solenoid valve according to claim 1 is characterized in that also being shaped on supporting band (9) on described slide block (2) sealing surface, and supporting band (9) and seal band (8) have constituted the sealing surface of slide block (2).
