Background technique
Ball valve is to make start-stop device for pipeline, and the open-shut device in valve body is spheroid, drives, and rotate around the axis of valve rod by valve rod, is mainly used in blocking or connecting the medium in pipeline, also can be used for adjusting and the control of fluid.For the ease of the assembling of spheroid and the maintenance of ball valve, ball valve body adopts spliced conventionally.
Sealing on existing market between most ball valve and ball valve core realizes by valve seat, in sealing traditional sense by valve seat, be called hard sealing, the long service life of hard sealing, but sealability is relatively poor, easily cause leakage, also between the ball valve having and ball valve core, adopt soft sealing structure mode, soft seal has good sealability can realize the problems such as zero earial drainage still also exists non-refractory, corrosion, and working life is short.
Model utility content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of ball valve that hard sealing long service life has again soft seal good seal performance simultaneously concurrently that has.
For achieving the above object, the utility model provides following technological scheme: a kind of ball valve, comprise rotatable handle, valve body, be located at the ball valve core in valve body, for driving the valve rod of ball valve core and being located at a pair of valve seat between described valve body and ball valve core, described valve rod one end is connected on described rotatable handle, the other end is connected with described ball valve core, in described valve body, be provided with the valve seat position suitable with described valve seat, described valve seat is placed in described valve seat position, described valve seat position is provided with positive stop, relatively described ball valve core one side of described valve seat is provided with draw-in groove, the relatively described ball valve core opposite side of described valve seat is provided with Compress Spring, in described draw-in groove, be provided with soft seal.
By adopting technique scheme, ball valve is first by improving valve body, have additional valve seat position, positive stop on valve seat position is guaranteed in the vertical direction spacing of valve seat, realize the self-locking of valve seat, the setting of Compress Spring is because it is all the time in compressive state, improve continually active force and guarantee the conflict of valve seat and ball valve core, guarantee sealing, a side in valve seat and ball valve core conflict is provided with draw-in groove and in draw-in groove, establishes soft seal, make this valve seat not only there is the feature that hard sealing long service life has again soft seal good seal performance simultaneously concurrently, realize mutually supplementing of hard sealing and soft seal.
This practicality is further set to: described valve body comprises left valve barrel and right valve barrel, and described left valve barrel and right valve barrel are connected with the first bolt, and the junction point of described left valve barrel and right valve barrel is provided with sealing gasket, and described left valve barrel and right valve barrel removably connect by the first bolt.
By adopting technique scheme, ball valve body is divided into left valve barrel and the dismountable linkage structure of right valve barrel is convenient to the assembling of spheroid and the maintenance of ball valve, raising service life.
This practicality is further set to: the outer sheathed stuffing box gland of described valve rod.
By adopting technique scheme, stuffing box gland guarantees valve stem seal, avoids because of the valve rod phenomenon that the flowing medium that causes leaks that moves up and down.
This practicality is further set to: described rotatable handle is detachably arranged on described valve rod.
By adopting technique scheme, rotatable handle is loaded onto when need are used, and when not using, disassembles, and avoids children's ignorant to the keying of ball valve and is connected to an antitheft effect.
This practicality is further set to again: described valve body is provided with stuffing box, and described stuffing box is provided with follower, and described follower and described valve body are connected with the second bolt, and described follower and described valve body removably connect by the second bolt.
By adopting technique scheme, the gap between the effective closed valve of stuffing box and valve rod, the outflow of prevention medium.
