Description
Technical field
The utility model is related to a kind of stop valve, especially with the stop valve of rubber cushion soft seal.
Background technology
Now widely used soft seal stop valve, its valve element lower end is provided with the seal gasket coordinated with valve seat, the sealing
Rubber cushion is coupled on valve element by screw；Its shortcoming is：1）Because valve element is provided with screwed hole, there is the possibility of leak；2）Screw is in water
Easily loosened in the presence of pressure, come off, cause seal gasket to fail, sealing property cannot ensure；3）Seal gasket bears high pressure, easily
Deformation retract, this can also influence sealing property.
Utility model content
The purpose of this utility model is the disadvantages mentioned above for overcoming prior art, there is provided a kind of soft seal stop valve, and it has
There is seal gasket to couple firm, on-deformable advantage, can for a long time ensure sealing property.
What the purpose of this utility model was realized in：
A kind of soft seal stop valve, including valve pocket, valve rod, the valve element that the valve body that integrally connects firmly and valve seat and valve body are connected,
Valve body is provided with water inlet and delivery port, and valve rod upper end couples with handwheel, and valve rod lower end passes through valve pocket, is provided between valve rod and valve pocket
Sealing ring, is provided with the spacing shaft shoulder on the valve rod in valve pocket, valve rod lower end passes through thread connection with valve element, it is characterised in that described
Valve element lower end is provided with annular deep gouge, and one section of radial direction draw-in groove being located above the shaft shoulder of valve element lower end, one are provided with the inside of annular deep gouge
Seal gasket is fixed on valve element lower end, and seal gasket is provided with the grab being placed in radial direction draw-in groove, and the lower surface of seal gasket is less than
The lower surface of valve element.
Seal gasket of the present utility model is fixed in the annular deep gouge of valve element lower end by injection moulding, and its grab is stuck in
In radial direction draw-in groove above the shaft shoulder of valve element lower end, have the advantages that connection firmly, will not fall off, without other connectors, also not
In the presence of connection screw, the possibility without leak, it is ensured that sealing property；
Used as further optimization of the present utility model, the lower end external diameter of seal gasket is equal with the lower end external diameter of valve element；Ring
Seal gasket on the outside of shape deep gouge can be supported by the outer shroud of valve element, be not easy to deform in the presence of water under high pressure, shunk, can be long-term
Ensure sealing property；
There is the utility model seal gasket to couple firm, on-deformable advantage, can for a long time ensure sealing property.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment.
Specific embodiment
The utility model is described in more detail below in conjunction with the accompanying drawings.
As shown in figure 1, the soft seal stop valve, including the valve body 1 that integrally connects firmly and valve seat 2 pass through screw thread phase with valve body 1
The valve pocket 3 of connection, valve rod 4, valve element 5, valve body 1 are provided with water inlet 6 and delivery port 7, and the upper end of valve rod 4 couples with handwheel 8, under valve rod 4
End is provided with sealing ring 9 through valve pocket 3 between valve rod 4 and valve pocket 3, the spacing shaft shoulder 10, valve rod are provided with the valve rod 4 in valve pocket 3
With valve element 5 by thread connection, the lower end of the valve element 5 is provided with annular deep gouge, one section is provided with the inside of annular deep gouge and is located at for 4 lower ends
Radial direction draw-in groove above the shaft shoulder of valve element lower end a, seal gasket 11 is fixed on the lower end of valve element 5, and seal gasket 11 is provided with and is placed in radially
Grab 12 in draw-in groove, the lower surface of the lower surface less than valve element 5 of seal gasket 11, the lower end external diameter and valve element of seal gasket 11
5 lower end external diameter is equal.
Seal gasket of the present utility model 11 is fixed in the annular deep gouge of the lower end of valve element 5 by injection moulding, its grab
12 are stuck in the radial direction draw-in groove above the lower end shaft shoulder of valve element 5, have the advantages that connection is firm, will not fall off, without other connections
Part, also in the absence of connection screw, the possibility without leak, the seal gasket 11 added on the outside of annular deep gouge can be by the outer shroud of valve element 5
13 supports, are not easy to deform, shrink in the presence of water under high pressure, can for a long time ensure sealing property.
