Abstract
The utility model relates to an inserted valve holder structure of double sealing for valve, valve holder structure includes the disk seat main part of installing in the valve body inner chamber, the disk seat main part is annular form, and the lateral wall of disk seat main part and valve body inner chamber interference fit, have sealed face in the upper end build -up welding of disk seat main part inside wall, and the sealed face in the disk seat main part constitutes sealed pair with the sealed face on the case is common, the lower extreme evenly distributed of disk seat main part has several positioning groove, has the several location arch corresponding with positioning groove simultaneously on the valve body. The utility model has the advantages of: the utility model discloses in, to impress the disk seat main part in the valve body inner chamber through external force, interference fit forms sealedly between disk seat outer wall and the valve body inner chamber to the problem of having avoided the deep hole to weld the easy fracture of sealed face, the positioning groove through the disk seat lower extreme sealed up with protruding formation the in the location on the valve body while, thus it is sealed to form twice, guarantees not have between inserted disk seat and the valve body to leak.
Description
Technical field
The utility model relates to a kind of valve, particularly the inserted valve seat construction of a kind of valve double seal.
Background technique
For the inserted valve seat in valve, in the process of installing it, traditional technological scheme is body built-up welding or the inserted valve seat only having one interference fit seal.
When utilizing such scheme to carry out installation valve seat, there is following shortcoming: first deep hole overlay-operation space is less, the workman visual field is bad, and sealing surface is easy to cracking; Only have the inserted valve seat of one interference fit seal once this road interference fit seal is leaked, then valve will inevitably interiorly leak.
Model utility content
The technical problems to be solved in the utility model is to provide the inserted valve seat construction of a kind of valve double seal, can effectively solve Deep Hole Welding sealing surface easy to crack, and conventional damascene formula valve seat only has the problem of one sealing.
For solving the problems of the technologies described above, the technical solution of the utility model is: the inserted valve seat construction of a kind of valve double seal, described valve comprises a valve body, there is the cavity holding medium circulation in valve body, also comprise the valve rod stretched in valve cavity, be provided with spool in the lower end of valve rod, the lower end of spool is provided with sealing surface, its innovative point is:
Described valve seat construction comprises one and is installed on valve seat body in body cavity, described valve seat body shape ringwise, and the outer side wall of valve seat body and body cavity interference fit, in the upper end of valve seat body madial wall, heap is welded with sealing surface, and the sealing surface in valve seat body and the sealing surface on spool form sealing pair jointly;
The lower end of described valve seat body is evenly distributed with several positioning groove, has several positioning convex corresponding with positioning groove on valve body simultaneously.
Further, described positioning convex can rectangular shape, also can be isosceles trapezoid shape.
The utility model has the advantage of: in the utility model, by external force, valve seat body is pressed in body cavity, thus avoid Deep Hole Welding sealing surface problem easy to crack, between valve seat outer wall and body cavity, interference fit is formed and seals, formed by the positioning convex on the positioning groove of valve seat lower end and valve body simultaneously and seal, thus formation two seals, ensure No leakage between inserted valve seat and valve body.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the inserted valve seat construction of valve double seal of the present utility model.
Embodiment
Schematic diagram is as shown in Figure 1 known, and valve of the present utility model comprises valve body 3, valve rod 1, spool 2 and valve seat construction.
In valve body 3, have the cavity of an appearance medium circulation, valve rod 1 stretches in the inner chamber of valve body 3 from top to bottom, is provided with spool 2 in the lower end of valve rod 1, and the lower end of spool 2 is provided with sealing surface.
Valve seat construction comprises one and is installed on valve seat body 4 in valve body 3 inner chamber, valve seat body 4 shape ringwise, and interference fit between the outer side wall of valve seat body 4 and valve body 3 inner chamber, in the upper end of valve seat body 4 madial wall, heap is welded with sealing surface, and the sealing surface in valve seat body 4 and the sealing surface on spool 2 form sealing pair jointly.
Be evenly distributed with several positioning groove in the lower end of valve seat body 4, simultaneously on valve body 3, have several positioning convex 5. corresponding with positioning groove in the utility model, positioning convex 5 can rectangular shape, also can be isosceles trapezoid shape.
Working principle: when assembling valve seat, first, valve seat body 4 is aimed at the upper end of the inner chamber of valve body 3, and ensure valve seat body 4 with positioning groove one end down, then by external force, valve seat body 4 is pressed in the inner chamber of valve body 3, when valve seat body 4 is pressed into positioning convex 5 position in valve body 3, after positioning convex 5 one_to_one corresponding in the positioning groove of valve seat body 4 lower end and valve body 3, then valve seat body 4 is continued compress.Deep Hole Welding sealing surface problem easy to crack is avoided by above-mentioned assembly method; In addition, between the inner chamber of valve seat body 4 outer wall and valve body 3, interference fit forms first and seals, form second by the positioning groove of valve seat body 4 lower end with the positioning convex on valve body 3 to seal simultaneously, thus formation two seals, ensure No leakage between inserted valve seat and valve body.
The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (2)
1. the inserted valve seat construction of valve double seal, described valve comprises a valve body, there is the cavity holding medium circulation in valve body, also comprise the valve rod stretched in valve cavity, in the lower end of valve rod, spool is installed, the lower end of spool is provided with sealing surface, it is characterized in that: described valve seat construction comprises one and is installed on valve seat body in body cavity, described valve seat body shape ringwise, and the outer side wall of valve seat body and body cavity interference fit, in the upper end of valve seat body madial wall, heap is welded with sealing surface, and the sealing surface in valve seat body and the sealing surface on spool form sealing pair jointly,
The lower end of described valve seat body is evenly distributed with several positioning groove, has several positioning convex corresponding with positioning groove on valve body simultaneously.
