Abstract
The utility model provides a double-seal structure for a stop valve. The double-seal structure is arranged at a position of a valve clack matched with a valve body, a seal groove matched with the valve body is arranged on the outer wall of the valve clack, the periphery of the bottom of the valve clack is protruded, and the middle of the bottom of the valve clack is inwardly concave relative to the periphery of the bottom of the valve clack. The annular seal groove is arranged on the outer wall of the valve clack of the stop valve, and when the valve clack is used with the valve body, the valve body can extend into the seal groove of the valve clack and is in seal fit with the seal groove. Besides, the periphery of the bottom of the valve clack is protruded, and the middle of the bottom of the valve clack is inwardly concave, so that the valve body is closely matched with the bottom of the valve clack to be sealed. The double-seal structure has the advantages that possibility of contact with media is reduced, damage of impurities to a seal surface is avoided, and the service 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 double sealing structure for stop valve.
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 double sealing structure that is used for stop valve of favorable sealing property.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
For the double sealing structure of stop valve, be arranged at the cooperation place of flap and valve body, described flap outer wall is provided with the sealed groove that cooperates with valve body; Flap bottom periphery is protruded and is arranged, and the middle part is the indent setting with respect to periphery.
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, and when flap and valve body were used, valve body can extend into the sealed groove of flap and be sealed and matched with it; For the flap bottom, protrude flap bottom periphery simultaneously, indent flap middle part makes valve body and flap bottom close fit, reaches sealing state.Double sealing structure of the present utility model has reduced the possibility with medium contact, has avoided the infringement of impurity for sealing surface, guarantees 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; 4 is the middle part of flap bottom; 5 is the periphery of flap bottom.
Embodiment
The utility model provides a kind of double sealing structure for stop valve, is arranged at the cooperation place of flap 2 and valve body 1.Specifically, a resealing is the outer wall place at flap 2, and the sealed groove 3 that cooperates with valve body 1 is set.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.Two resealings are the bottoms at flap 2.Flap 2 bottom peripheries 5 arrange for protruding, and middle part 4 then presents the indent setting with respect to periphery 5.Like this, when valve body 1 and flap 2 bottom close fit, can reach equally the state of sealing.
Double sealing structure of the present utility model has reduced the possibility with medium contact, has avoided the infringement of impurity for sealing surface, guarantees the use safety of stop valve.
Claims (2)
1. for the double sealing structure of stop valve, be arranged at the cooperation place of flap and valve body, it is characterized in that described flap outer wall is provided with the sealed groove that cooperates with valve body; Flap bottom periphery is protruded and is arranged, and the middle part is the indent setting with respect to periphery.
2. the double sealing structure for stop valve according to claim 1 is characterized in that described sealed groove is around the setting of flap outer wall.
