Abstract
Technical problem to be solved in the utility model is to provide the valve element and valve base sealing structure of a kind of three-way magnetic valve, including valve seat and valve element, the bottom of valve seat has a circular trough, one end of valve element is inserted in circular trough, valve element, which is located on the end face in circular trough, has a ring annular groove, and the bottom land of annular groove has several blind round hole, a sealing ring is placed with annular groove, the groove top of circular trough is pressed at the top of sealing ring, the bottom of sealing ring is connected with the spring being placed in blind round hole.Even if sealing ring has abrasion in use, thickness diminishes, but spring press effect under, sealing ring still can be compressed tightly against on valve seat, in the case of long-term use of, ensure that zero leakage between valve element and valve seat.
Description
Technical field
It the utility model is related to the valve element and valve base sealing structure of a kind of valve, in particular to three-way magnetic valve.
Background technology
One of the main leakage point of the junction of valve seat and valve element as valve, current sealing structure are to use sealing ring
It is in contact with valve seat to reach sealing, because valve element is more frequent with contacting with the mechanically decoupled of valve seat, the contact face of valve element
Abrasion is also easy to produce, causes sealing effectiveness to reduce.
Utility model content
The purpose of this utility model is the valve element and valve base sealing structure for providing a kind of life.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
The valve element and valve base sealing structure of three-way magnetic valve, including valve seat and valve element, the bottom of the valve seat have one
Circular trough, one end of the valve element are inserted in the circular trough, and the valve element, which is located on the end face in the circular trough, has one
Ring annular groove, the bottom land of the annular groove have several blind round hole, and a sealing ring is placed with the annular groove, described close
The groove top of the circular trough is pressed at the top of seal, the bottom of the sealing ring and the spring being placed in the blind round hole connect
Connect.
It is further that the groove top of the circular trough is formed down a cylindrical projection, the top tool of the valve element
There is a groove, the projection is inserted in the groove；The stomata of three air flues of magnetic valve is in the projection.
It is further that the bottom of the valve seat is provided with several locating dowels, the valve element around the circular trough
End cap on be provided with the positioning hole for holding locating dowel insertion.
Compared with prior art, the beneficial effects of the utility model are：It is thick even if sealing ring has abrasion in use
Degree diminishes, but spring press effect under, sealing ring still can be compressed tightly against on the valve seat, long-term use of situation
Under, it ensure that zero leakage between valve element and valve seat.
Brief description of the drawings
, below will be to existing skill in order to illustrate more clearly of the technical scheme in the utility model prior art and embodiment
The required accompanying drawing used is briefly described in art and embodiment description.
Fig. 1 is the structural representation of valve element and valve seat disclosed in the present embodiment；
Fig. 2 is the stereogram of valve seat disclosed in the present embodiment；
Fig. 3 is the sectional view of valve element disclosed in the present embodiment.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe.
Embodiment one
Valve seat 1 and valve element 2 shown in Figure 1, the bottom of valve seat have a circular trough 3, and one end of valve element is inserted in circle
In shape groove, valve element, which is located on the end face in circular trough, has a ring annular groove 4, and the bottom land of annular groove has several blind round hole 5,
A sealing ring 6 is placed with annular groove, the groove top of circular trough is pressed at the top of sealing ring, the bottom of sealing ring is with being placed on circle
Spring 7 in shape blind hole connects.Even if sealing ring has abrasion in use, thickness diminishes, but presses work in spring
Under, sealing ring still can be compressed tightly against on valve seat, in the case of long-term use of, ensure that zero between valve element and valve seat lets out
Dew.
It is further that the groove top of circular trough is formed down a cylindrical projection 8, the gas of three air flues of magnetic valve
Hole position is in projection；The top of valve element has a groove 9（Referring to Fig. 3）, it is raised to insert in a groove.Projection insertion groove, with
Valve element inserts annular groove and has formed a lenticular location structure so that is positioned between valve element and valve seat more accurate.
Embodiment two
Referring to Fig. 2 and 3, the bottom of valve seat is provided with several locating dowels 10 around circular trough, is set on the end cap of valve element
It is equipped with the positioning hole 11 for holding locating dowel insertion.So that being positioned between valve element and valve seat more accurate in locating dowel insertion positioning hole.
A variety of modifications to these embodiments will be apparent for those skilled in the art, herein
Defined General Principle can be real in other embodiments in the case where not departing from spirit or scope of the present utility model
It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein
Principle and the consistent most wide scope of features of novelty.
