Abstract

The utility model discloses a nesting plug cock valve composed of a valve body, a plug cock body and a lining. The plug cock valve is respectively provided with annular convex ribs at the inner walls of valve chambers of an inlet side and an outlet side of the valve body around inlet and outlet directions, and the plug cock valve prevents the lining from longitudinally moving or rotating around the center of the plug cock body in an opening and closing process. Meanwhile, the indirect contact area of the plug cock body and the valve body is reduced. Thereby, the opening and closing friction is reduced. The utility model has the advantages of portability, lightness, high adaptive pressure, reliable sealing performance long service life, etc.

Description

The nesting type stopcock

The utility model relates to a kind of valve, specifically about a kind of stopcock.

Stopcock generally comprises valve body, faucet body, cock stem and valve gap, and domestic stopcock has hard sealing stopcock and rubber lined stopcock at present.The valve body of hard sealing stopcock and the area of contact of faucet body are big, require to have very high machining accuracy between both fitting surfaces, hoisting capacity is very big, so can only be applicable to the operating mode that pressure medium is less, and the friction between valve body and faucet body is big in opening-closing process, easy to wear and leak between fitting surface, working life is short.The lining that rubber lined stopcock is made at valve interior surface lining one deck plastic materials, realize sealing by faucet body and lining fitting surface, the shortcoming of this structure stopcock is: area of contact is big between cock body and the lining, hoisting capacity is big, can only be applicable to the operating mode that pressure is less, and lining comes unstuck with valve body easily and vertical shift and with the rotation of faucet body center under the hoisting capacity effect, influences the sealing reliability and the working life of stopcock.

The purpose of this utility model is at the deficiencies in the prior art, designs that a kind of hoisting capacity is little, sealability is reliable, long service life, can be applicable to the stopcock of high pressure operating mode.

The technical solution of the utility model comprises valve body, lining, faucet body, cock stem, valve gap, Sealing and assembling set, is shaped on respectively around the annular convex rib of inlet/outlet direction at the valve pocket inwall of valve body import and outlet side.

To be valve body prevent effectively that into and out of the convex tendon of oral-lateral lining from vertically moving or rotating around the faucet body center when the valve opening and closing to the utility model beneficial effect compared with prior art, reduce the mediate contact area of faucet body and valve body simultaneously, thereby reduce the friction of valve opening and closing, open and close light and flexible, be suitable for pressure height, good seal performance, long service life.

Fig. 1 is the utility model stopcock structure schematic representation.

Fig. 2 is a stopcock valve pocket channel direction schematic representation among the utility model Fig. 1.

Now describe the technical solution of the utility model in conjunction with the accompanying drawings and embodiments in detail.Stopcock shown in Figure 1 comprises valve body 1, lining 5, faucet body 4, cock stem 6, valve gap 7, Sealing and assembling set, is shaped on annular convex rib 2 around import and Way out respectively at the valve pocket inwall of the import of valve body 1 and outlet side.Annular convex rib has 2.As shown in Figure 2, be shaped on annular groove 3 respectively on the valve pocket of valve body 1 bottom and top around faucet body 4 circumferencial directions.Be shaped on lining 5 at the valve body cavity wall, lining 5 is made by plastic materials, and shown in Figure 1, valve gap 7 is connected with valve body 1 by bolt.
