Abstract
A kind of stopcock with rotation prevention structure, comprise: valve body, cock, cock stem, valve gap and the seal ring be arranged between valve body and cock, seal ring is provided with for the through hole by medium, and it is corresponding with the lead to the hole site in cock, valve interior surface has wedge-shaped impression from top to bottom, wedge-shaped impression is arranged in valve interior surface circumference, and quantity is at least 1; The internal surface of seal ring and the conical surface of cock are fitted, and the outer surface of seal ring is provided with wedge shape boss with wedge-shaped impression corresponding part, and wedge shape boss abuts mutually with wedge-shaped impression.The beneficial effects of the utility model are: the wedge-shaped impression that the wedge shape boss that seal ring is arranged and valve interior surface are arranged abuts mutually, effectively avoid seal ring displacement, improve sealing reliability, extend the working life of stopcock when cock is rotated.
Description
Art
The utility model relates to a kind of valve, particularly relates to a kind of stopcock.
Background technique
At present, rubber lined stopcock of the prior art arranges lining at valve interior surface, realized sealing by faucet body and lining fitting surface, but this structure faucet body and bushing interface amass large, hoisting capacity is large, under hoisting capacity effect, lining is easily with faucet body center rotating, affects sealing reliability and the working life of stopcock.
Model utility content
In order to overcome the above-mentioned shortcoming of existing stopcock structure, the utility model provides a kind of stopcock with rotation prevention structure.
It is that a kind of stopcock with rotation prevention structure, comprising that the utility model solves the technological scheme that its technical problem adopts:
Valve body, comprises the cavity that is positioned at center region and for the passage by medium;
Cock, is rotatablely located in the cavity of described valve body, and is provided with for the through hole by medium, and the shape of cock is taper;
Cock stem, is fixedly connected with cock in the valve gap;
Valve gap, to be sleeved on cock stem and to be fixedly connected with valve body, seal ring is provided with between valve body and cock, seal ring is provided with for the through hole by medium, and it is corresponding with the lead to the hole site in cock, valve interior surface has wedge-shaped impression from top to bottom, and wedge-shaped impression is arranged in valve interior surface circumference, and quantity is at least 1;
The internal surface of seal ring and the conical surface of cock are fitted, and the outer surface of seal ring is provided with wedge shape boss with the wedge-shaped impression corresponding part of valve interior surface, and wedge shape boss abuts mutually with wedge-shaped impression.
The beneficial effects of the utility model are: the wedge-shaped impression that the wedge shape boss that seal ring is arranged and valve interior surface are arranged abuts mutually, effectively avoid seal ring displacement, improve sealing reliability, extend the working life of stopcock when cock is rotated.
Accompanying drawing explanation
Fig. 1 is the structural representation of embodiment;
Fig. 2 is the structural representation of parts 5 in Fig. 1.
In figure: 1. cock stem; 2. valve gap; 3. valve body; 4. cock; 5. seal ring; 301. wedge-shaped impression; 501. wedge shape boss.
Embodiment
As shown in Figure 1, 2, a kind of stopcock with rotation prevention structure, comprising:
Valve body 3, comprises the cavity that is positioned at center region and for the passage by medium;
Cock 4, is rotatablely located in the cavity of described valve body 3, and is provided with for the through hole by medium, and the shape of cock 4 is taper;
Cock stem 1, is fixedly connected with cock 4 in the valve gap 2;
Valve gap 2, to be sleeved on cock stem 1 and to be fixedly connected with valve body 3, seal ring 5 is provided with between valve body 3 and cock 4, seal ring 5 is provided with for the through hole by medium, and it is corresponding with the lead to the hole site in cock 4, valve body 3 internal surface has wedge-shaped impression 301 from top to bottom, and wedge-shaped impression 301 is arranged in valve body 3 internal surface circumference, and quantity is at least 1;
The internal surface of seal ring 5 and the conical surface of cock 4 are fitted, and the outer surface of seal ring 5 is provided with wedge shape boss 501 with wedge-shaped impression 301 corresponding part of valve interior surface, and wedge shape boss 501 abuts mutually with wedge-shaped impression 301.
Stopcock due to the wedge shape boss 501 above seal ring 5 and the clamping of wedge-shaped impression 301 on valve body, avoids the displacement of seal ring 5, improves the sealability of stopcock in opening-closing process.
