Description
Technical field
The utility model relates to valve technology field, specifically a kind of anti-soil type high-pressure ball valve.
Background technique
Ball valve is a kind of valve that is driven spherical valve core and rotated around the axis of valve rod by valve rod, ball valve is mainly used to make the flow direction that cuts off, distributes and change medium in pipeline, existing ball valve when in use in the market, when medium is messy or have in short grained situation, impurity easily enters between spheroid and ball seat sealing, cause spheroid and ball seat sealing wear, and then affect the normal use of ball valve, so working life is shorter.
Model utility content
The utility model provides a kind of anti-soil type high-pressure ball valve of simple in structure, long service life.
The utility model is achieved through the following technical solutions:
A kind of anti-soil type high-pressure ball valve, comprise valve body, spheroid and valve rod, described valve body is hollow shape, described valve body two ends are respectively equipped with a joint in the axial direction, described spheroid is located between described two joints and is positioned at described valve inner, valve body described in the break-through diametrically of described valve rod, and be connected with described spheroid, described spheroid is provided with opening in the axial direction, the inner of described joint is provided with first step and second step, between the outer surface of described spheroid and described first step, be provided with a ball seat sealing, between described outer surface of spheroid and described second step, be positioned at described ball seat sealing inner side and be provided with a dust blowing ring, the diameter of described dust blowing ring madial wall is identical with the diameter of described opening.
The outer side wall of described joint the inner is provided with outside thread, and the madial wall at described valve body two ends is provided with internal thread, and described joint is cooperatively interacted and is connected with described valve body by outside thread and internal thread.
The externally threaded outside that is positioned at described valve body between described valve body and described joint is respectively equipped with first "O"-ring.
The outer side wall of described valve rod is provided with a circle groove, is provided with second "O"-ring in described groove.
The below that is positioned at described groove on described valve rod is provided with a circle convex tendon, and described valve body is provided with the 3rd step, between the upper surface of described convex tendon and described the 3rd step, is provided with a Support cushion.
The beneficial effect that the utility model brings is:
In the utility model, described anti-soil type high-pressure ball valve comprises valve body, spheroid and valve rod, described valve body and spheroid coordinate to make the flow direction that cuts off, distributes and change medium, user only needs very little power to rotate the spheroid that described valve rod is rotatable valve body inside, realizes closing or opening of ball valve; The design of described ball seat sealing can well prevent that the impurity in medium from entering between described ball seat sealing and spheroid, reduces wear; Arranging of described dust blowing ring can reduce the erosion of swiftly flowing medium to ball seat sealing, improved the stain resistance of ball valve, and then extended the working life of ball valve.
