Abstract
The utility model provides a stop valve with high sealing performance. The stop valve comprises bidirectional sealing surfaces. The bidirectional sealing surfaces are arranged on the stop valve, a good impurity stopping effect can be realized as compared with a one-way sealing surface in the prior art, and the service safety of the stop valve is guaranteed.
Description
Technical field
The utility model relates to a kind of stop valve, is specifically related to a kind of strong sealing stop valve.
Background technique
Stop valve belongs to forced seal formula valve, so when valve closing, must exert pressure to flap, does not leak with forced seal face.At present common stop valve only adopts the single face sealing, namely only has a sealing surface, uses in reality, is brought in the stop valve because the existence of medium can permit this impurity unavoidably, and the easy like this valve sealing face that causes is impaired and cause leakage.
The model utility content
For above problems of the prior art, the utility model provides a kind of strong sealing stop valve of good seal performance.
The utility model is by realizing with technological scheme:
Strong sealing stop valve comprises sealing surface, and described stop valve comprises the two way sealed face.
The beneficial effects of the utility model are: at stop valve the two way sealed face is set, with respect to one-way sealing front cover of the prior art, can reaches the effect that better stops impurity, guarantee the use safety of stop valve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is stop valve; 2 is sealing surface.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further details.
The utility model provides a kind of strong sealing stop valve, and innovation of the present utility model is in being provided with two way sealed face 2 at stop valve 1.Two way sealed face 2 can reach the effect that better stops impurity with respect to one-way sealing front cover of the prior art, guarantees the use safety of stop valve.
