Abstract
The utility model discloses a piece piling type sealing ring for a plunger valve, which is used on a plunger valve. The utility model is formed by piling multiple ring bodies, wherein the two adjacent ring bodies adhere together with adhesive. The piece piling type sealing ring for a plunger valve has the characteristics of high anti-flat radial pulling force, good rebound resilience and good sealing properties, and can improve the wear-resisting properties of the plunger valve and prolong the service life of the plunger valve.
Description
The utility model relates to a kind of seal ring, particularly plunger valve ring.
Plunger valve is chemical industry a kind of valve commonly used.Because the fluid through plunger valve often has higher temperature and bigger pressure, therefore resistance to compression and the resistance to heat to plunger valve has strict requirement.At present, the seal ring of plunger valve often deforms because of high pressure and high temperature, causes the decreased performance of plunger valve, and shorten working life.
The purpose of this utility model is at present existing the problems referred to above, and a kind of compressive strength height, multiple pieces piling type plunger valve ring that resistance to heat is good are provided.
The purpose of this utility model adopts following scheme to realize: this multiple pieces piling type plunger valve ring is by some overlapping the forming of circle body, adopts adhesive bonds together between adjacent two circle bodies.During use, can select the thickness of suitable circle body material, sheet number and every circle body according to the size of plunger valve and purposes.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the sectional view of this multiple pieces piling type plunger valve ring.
As shown in the figure, seal ring is by five overlapping forming of circle body in the present embodiment.Usually the sheet number of circle body is decided according to actual conditions more than three.General employing resinae adhesive bonds together between adjacent two circle bodies.For can be high temperature resistant, circle body adopts exotic materials such as carbon fiber or asbestos fiber to make in the present embodiment.Show that through test this seal ring can anti-high temperature below 580 ℃.
This multiple pieces piling is compared with the conventional seals circle, owing to adopt the multi-disc circle body heavy Folded forming so anti-planar radial pulling force is very high, stood washing away of high-pressure fluid medium; Simultaneously, This sealing ring also has good resilience and sealing. After plunger valve uses this sealing ring, energy Improve anti-wear performance, increase the service life.
Claims (3)
1, a kind of multiple pieces piling type plunger valve ring is characterized in that the sealing circle is by some overlapping the forming of circle body, adopts adhesive bonds together between adjacent two circle bodies.
2, multiple pieces piling type plunger valve ring according to claim 1 is characterized in that described adhesive adopts the resinae adhesive.
3, multiple pieces piling type plunger valve ring according to claim 1 and 2 is characterized in that described circle body adopts exotic materials such as carbon fiber or asbestos fiber to make.
