Abstract
The utility model discloses a spherical valve, which comprises a valve body (2), a gland (5), a spherical valve core (4) and a valve rod (1), the spherical valve core (4) and the valve rod (1) which are arranged in the valve body (2) are connected into a whole, and a sealing seat (3) is arranged in the valve body (2) and positioned through the gland (5). The utility model is characterized in that the sealing seat (3) is provided with a groove (6) which has the elasticity when the sealing seat (3) is pressed tightly by the gland (5), and the inner end surface of the sealing seat (3) is always combined with the spherical surface (4) of the valve core in an embracing way. The utility model has the advantages of good sealing performance and long service life, besides, the utility model can not be influenced by the pipeline pressure during operation.
Description
[technical field]
The utility model relates to a kind of improvement invention of valve, particularly be that the structure of sealing seat is carried out improved ball valve in a kind of valve body.
[background technique]
In the prior art, the kind of ball valve is a lot, generally all comprise valve body, gland, sphere core and valve rod, and have water intake and a water outlet, in water outlet, for fear of leakage, generally will carry out close-fitting between the spool sphere of ball valve and the sealing seat interior edge face in the water outlet, the close-fitting mode of sealing seat is that spring is set on sealing seat, utilizing the elasticity of spring to come the spool sphere compressed realizes, such structure, the process complexity of its assembling is in long using process, the sludge of medium can enter spring, make spring can produce the elastic failure phenomenon, and cause the sealing of sealing seat and sphere core not tight, and can leak.For ball valve, this technical disadvantages is that those skilled in the art want to solve and insoluble problem always.
[summary of the invention]
In view of the problem that known technology exists, the technical problems to be solved in the utility model provides a kind of good seal performance, and sealing seat and sphere core can carry out the ball valve of close-fitting all the time.For achieving the above object, the utility model is finished by following mode: this ball valve includes valve body, gland, sphere core and valve rod, described sphere core and the valve rod that is located in the valve body connects as one, be provided with sealing seat in the described valve body, the sealing seat compresses the location by gland, it is characterized in that described sealing seat is provided with at sealing seat is glanded rubber-like groove when compressing, the interior edge face of described sealing seat all the time with the obvolvent of spool sphere.When the utility model utilizes sealing seat compacted,, make sealing seat obvolvent sphere core all the time, and reach the effect of sealing because the effect of its upper groove can produce elasticity.
[description of drawings]
The utility model is by following accompanying drawing:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model sealing seat;
[specific embodiment]
Accompanying drawing has been represented specific embodiment of the utility model, further describe the relevant details of embodiment below again, include valve body 2, gland 5, sphere core 4 and valve rod 1, the described sphere core 4 that is located in the valve body 2 connects as one with valve rod 1, be provided with sealing seat 3 in the described valve body 2, sealing seat 3 compresses the location by gland 5, described sealing seat 3 is provided with at sealing seat 3 and is glanded 5 grooves of rubber-like when compressing 6, the interior edge face of described sealing seat 3 all the time with 4 obvolvents of spool sphere, described sealing seat 3 is made by steel disc, during installation, only need sealing seat 3 is placed in the valve body 2, with gland 5 it is fixed again, with the tight obvolvent of sphere of spool 4, because the effect of sealing seat 3 upper grooves 6, sealing seat 3 can produce a kind of elastic force when compacted, thereby it can be for a long time and sphere core 4 obvolvents, has excellent sealing performance.Therefore also prolonged its working life, the problem of having avoided the loss of elasticity because of spring to exist.According to the ball valve of the utility model design motif made, will bring positive using effect to users.
Claims (1)
1, a kind of ball valve, include valve body (2), gland (5), sphere core (4) and valve rod (1), the described sphere core (4) that is located in the valve body (2) connects as one with valve rod (1), be provided with sealing seat (3) in the described valve body (2), sealing seat (3) compresses the location by gland (5), it is characterized in that described sealing seat (3) is provided with at sealing seat (3) is glanded (5) rubber-like groove (6) when compressing, the interior edge face of described sealing seat (3) all the time with spool sphere (4) obvolvent.
