Abstract
The utility model discloses a seal structure of a valve clack of a stop valve. The seal structure is a seal groove which is arranged on the outer wall of the valve clack and matched with a valve body. Since the annular seal groove is arranged on the outer wall of the valve clack of the stop valve, when the valve clack is used with the valve body, the valve body can extend into the seal groove of the valve clack to be in seal fit with the seal groove, contact possibility of the valve body with media is decreased, damage of impurities to a sealing face is avoided, and use safety of the stop valve is guaranteed.
Description
Technical field
The utility model relates to the stop valve structure field, relates generally to a kind of stop valve clack sealing configuration.
Background technique
In common stop valve, usually adopt plane sealing or linear sealing to use as sealing configuration between valve body and the flap.But use in reality, brought in the stop valve because the existence of medium can permit this impurity unavoidably, 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 air-proof condition good stop valve clack sealing configuration.
The utility model is achieved through the following technical solutions:
The stop valve clack sealing configuration, described sealing configuration is for being arranged at the flap outer wall, the sealed groove that cooperates with valve body.
Described sealed groove arranges around the flap outer wall.
The beneficial effects of the utility model are: the flap outer wall at stop valve arranges the annular seal groove, when flap and valve body are used, valve body can extend into the sealed groove of flap and be sealed and matched with it, reduced the possibility with medium contact, avoid the infringement of impurity for sealing surface, guaranteed the use safety of stop valve.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure: 1 is valve body; 2 is flap; 3 is sealed groove.
Embodiment
The utility model provides a kind of stop valve clack sealing configuration, and the flap sealed junction is arranged at the outer wall place of flap 2 specifically, is the sealed groove 3 that cooperates with valve body 1.For realizing closely and cooperate fully, the utility model is arranged to outer wall around flap 2 with sealed groove 3, namely consists of the sealed groove 3 of an annular.Like this, when flap 2 and valve body 1 were used, valve body 1 can extend into the sealed groove 3 of flap 2 and be sealed and matched with it, had reduced the possibility with medium contact, had avoided the infringement of impurity for sealing surface, guaranteed the use safety of stop valve.
Claims (2)
1. the stop valve clack sealing configuration is characterized in that described sealing configuration is for being arranged at the flap outer wall, the sealed groove that cooperates with valve body.
2. stop valve clack sealing configuration according to claim 1 is characterized in that described sealed groove is around the setting of flap outer wall.
