Abstract
The utility model discloses a seal structure of a sleeve valve, which comprises a sleeve and a valve body, wherein the seal surface of the sleeve is in a step structure; the valve body is provided with a step surface fitting the step of the sleeve; the step seal surface of the sleeve is provided with a ring-shaped boss; and the boss cooperates with the step surface of the valve body to form a linear seal structure. The ring-shaped boss on the step seal surface of the sleeve of the utility model cooperates with the step surface of the valve body to form the linear seal structure with good rigidity; the seal structure has the characteristics of corrosion resistance, pressure resistance and high strength; the seal structure avoids the defects that the traditional spacers are easy to damage and leak, can reach the higher leakage grade seal requirements and has high reliability and long service life.
Description
Technical field:
The utility model relates to a kind of telescoping valve, relates in particular to a kind of sealing configuration of telescoping valve.
Background technique:
In the sleeve of conventional sleeve valve and the seal form of valve body, shimming is modal form (referring to Fig. 3, Fig. 4), and this kind structure is easy to sealing and good sealing effect.But because the pad that uses generally all is a non-metallic material, as tetrafluoro etc., i.e. soft seal form.Relatively poor and the easy damage generation leakage of the seal form intensity of this employing pad, corrosion resistance and resistance to pressure are relatively low; The pad of non-metallic material is subjected to medium kind and Temperature Influence bigger in addition, has shortened the working life of telescoping valve.
Summary of the invention:
The purpose of this utility model provides a kind of telescoping valve sealing configuration that can overcome above-mentioned deficiency.
The utility model is to adopt following technological scheme to realize:
A kind of sealing configuration of telescoping valve, comprise sleeve and valve body, the sealing surface of described sleeve is a ledge structure, described valve body has and the suitable step surface of the step of sleeve, has an annular boss on the step sealing surface of described sleeve, this boss cooperates with the step surface of valve body, forms the linear sealing structure.
The beneficial effects of the utility model are: the annular boss on the step sealing surface of sleeve matches with the step surface of valve body, form the linear sealing structure of good rigidly, have corrosion-resistant, withstand voltage, advantages of high strength, avoided conventional spacers to seal defective fragile, easy leakage, can reach higher leakage class seal request, the reliability height, long service life.
Description of drawings:
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the local A place enlarged view of Fig. 1.
Fig. 3 is existing sleeve seal structural representation.
Fig. 4 is the local B place enlarged view of Fig. 3.
Embodiment:
Referring to Fig. 1, Fig. 2: the utility model comprises the sleeve 1 and the valve body 2 of metal material.The sealing surface of this sleeve 1 is a ledge structure, and valve body 2 has and the suitable step surface of the step of sleeve 1.Have an annular boss 3 on the step sealing surface of sleeve 1, this boss 3 cooperates with the step surface of valve body 2, forms the linear sealing structure of metal, good rigidly.Like this, avoided that traditional non-metallic material gasket seal is fragile, the defective of easy leakage, had corrosion-resistant, withstand voltage, advantages of high strength.
