Abstract
The utility model discloses the open flume type sealing structures on a kind of three-flat ball valve, make the seal receptacle of the three-flat ball valve and the connection type open flume type sealing structure of valve body.The open flume type sealing structure is equipped with a L-type fluting on the valve body, and the fluting is set between the seal receptacle and valve body.Meanwhile two end faces that valve body is contacted with seal receptacle are R3~5mm rounded structure.Pass through the open flume type sealing structure, it not only ensure that the leakproofness between the valve body and seal receptacle, also reduce the compression area of valve body and seal receptacle, when sphere squeezes seal receptacle, set open flume type sealing structure provides for seal receptacle and makes a concession space, make the more flexible rotation of sphere, reduce the switching torque of ball valve, is conducive to manual switch.When three-flat ball valve is in running order, the impurity in the ball valve medium can be reduced impact when passing through sealing surface, and reduce damage of the impurity to sealing surface, extend seal receptacle service life.
Description
Technical field
Open flume type sealing structure the utility model relates to ball valve field, in particular on a kind of three-flat ball valve.
Background technique
Three-flat ball valve major function in pipeline is turned off or connects fluid channel, has extensively in marine valve field
Effect.Existing three-flat ball valve seal receptacle is bumped into valve body mostly, and seal receptacle and valve body are in close contact.When ball valve open with
When closing, opening and closing torque will increase.Since its seal receptacle and valve body are in close contact, the impact of medium and impurity in medium can be right
Ball-valve sealing base generates certain influence, reduces seal receptacle service life.
Utility model content
The purpose of this utility model is changed described using a kind of open flume type sealing structure on three-flat ball valve
The seal receptacle of three-flat ball valve with valve body is original connects connection type, increase the flexible of the sphere rotation of the three-flat ball valve
Property.The open flume type sealing structure reduces the compression area of valve body and seal receptacle, when sphere squeezes seal receptacle, set fluting
Formula sealing structure provides for seal receptacle and makes a concession space, makes the more flexible rotation of sphere, reduces the switching torque of ball valve, conducive to opening manually
It closes.Under operating pressure, reduce the impact to three-flat ball valve seal receptacle.Also have when having impurity embedding sealing seat simultaneously certain
Buffer function.
In order to achieve the goal above, making institute the utility model proposes the open flume type sealing structure on a kind of three-flat ball valve
The connection type of the seal receptacle and valve body of stating three-flat ball valve is open flume type sealing structure, keeps seal receptacle to connect with valve body close
Feng Xing increases the flexibility of the sphere rotation of the three-flat ball valve.
The open flume type sealing structure is equipped with a L-type fluting on the valve body, and the fluting is set to the sealing
Between seat and the valve body.
The width of the fluting is 3~5mm.
Two end faces that the valve body is contacted with seal receptacle are the rounded structure of R3~5mm.
The utility model compared with prior art, has the advantage that the open flume type sealing structure of the utility model not only
The leakproofness between seal receptacle and valve body is maintained, by reducing the compression area of seal receptacle and valve body, is sealed when sphere squeezes
When seat, set open flume type sealing structure provides for seal receptacle and makes a concession space, so that opening and turning round in three-flat ball valve rotational handle
Square is reduced, being capable of more convenient manual opening and closing.When three-flat ball valve is in running order, the impurity in the ball valve medium exists
By can be reduced impact when sealing surface, and damage of the impurity to sealing surface is reduced, extending seal receptacle service life, reduces sealing
Seat replacement frequency.

Specific embodiment
The technical solution of the utility model is described further below in conjunction with attached drawing.
The purpose of this utility model is using a kind of open flume type sealing structure on three-flat ball valve, so that the ball
The seal receptacle 4 of valve and the connection type of valve body 2 become open flume type sealing structure from the sealing structure of close contact, keep sealing
The leakproofness that seat 4 is connect with valve body 2.The open flume type sealing structure reduces and seals to three-flat ball valve under operating pressure
The impact of seat 4.Also there is certain buffer function when having impurity embedding sealing seat 4 simultaneously.The open flume type sealing structure can make
The ball valve switch torque is reduced, and when opening and closing is lighter.
Fig. 1 is the structural schematic diagram using the three-flat ball valve of the utility model open flume type sealing structure.Fig. 2 is this reality
With the open flume type sealing structure enlarged diagram on novel three-flat ball valve.As depicted in figs. 1 and 2, in order to realize the above mesh
, the open flume type sealing structure of the utility model is equipped with a L-type fluting 1 on the valve body 2, and the fluting 1 is set to institute
It states between seal receptacle 4 and the valve body 2.As shown in Fig. 2, the width d of the fluting 11And d2It is identical, it is 3~5mm.
Two end faces that the valve body 2 is contacted with seal receptacle 4 are the rounded structure of R3~5mm.The rounded structure tool
Body refers to the first valve body fillet 3 and the second valve body fillet 6 in Fig. 2.
When opening or closing ball valve, by rotational handle 7, sphere 5 is driven to rotate.The utility model is by reducing sealing
The compression area of seat 4 and valve body 2, when sphere 5 squeezes seal receptacle 4, set open flume type sealing structure is that seal receptacle 4 provides yielding
Space, makes the more flexible rotation of sphere 5, and when rotational handle 7, open torque is reduced, being capable of more convenient manual opening and closing.
Although the content of the utility model has been discussed in detail, but it should be appreciated that the description above is not construed as
It is limitations of the present invention.After those skilled in the art have read above content, a variety of for the utility model are repaired
Changing and substituting all will be apparent.Therefore, the protection scope of the utility model should be limited to the appended claims.
