Abstract
The utility model discloses a ball valve capable of automatically adjusting sealing, comprising a valve body and a ball-shaped valve core positioned in the valve body whose water outlet is provided with a seal washer. The water inlet of the valve body is provided with a circular tube bush whose inner part is provided with a round hole in which a spring is arranged. A movable spacer is arranged between the bush and the ball-shaped valve core; the ball-shaped seal of the movable spacer is contacted with the ball-shaped valve core, and the rear end of the movable spacer is inserted into the groove of the bush and contacted tightly with the spring. Compared with prior art, the utility model provides with multiple seal can automatically adjust the seal of the movable spacer and the ball-shaped valve core especially and ensure the great property of the dynamic seal of the valve core; additionally, the valve core has flexible rotation and long service life.
Description
Technical field
The utility model relates to a kind of ball valve, the particularly a kind of ball valve that can regulate sealing automatically.
Background technique
Traditional ball valve is made up of valve body, spherical valve core and seal ring, and spherical valve core is positioned at valve inner, is provided with seal ring at the water intake and the water outlet of valve body, and seal ring directly contacts with spool.This structure spool on the one hand is subjected to pressing of seal ring, and is very painstaking when rotating, and the opposing party can make the wearing and tearing aggravation of spool, shortened the working life of spool; Water leakage phenomenon will take place in case wearing and tearing the gap occurs at seal ring and spool contacting point in spool.
The model utility content
The purpose of this utility model is to provide the ball valve that can regulate sealing after a kind of wearing and tearing automatically, guarantees that valve core rotation is flexible, good seal performance, long service life.
For achieving the above object, the utility model has adopted following technological scheme:
A kind of ball valve that can regulate sealing automatically, include valve body, spherical valve core, spherical valve core is positioned at valve inner, the water outlet place of valve body is provided with seal washer, it is characterized in that: the water inlet of valve body is provided with a circular pipe lining, and its front end is provided with annular groove, and a plurality of circular holes are set in the groove, be provided with spring in each circular hole, the original length of its medi-spring is greater than hole depth; Between lining and spherical valve core removable insole pieces is set, removable insole pieces is an annulus, and its front-end face is a spherical, and contacting with spherical valve core is spherical sealing, and the rear end is inserted in the groove of lining and with spring and contacts mutually; Between the dual-side of removable insole pieces and lining groove, respectively be provided with seal ring, be provided with a plurality of seal rings between lining and the valve body.
Above-mentioned circular hole evenly distributes around removable insole pieces groove circumference;
One through hole is arranged in the middle of the above-mentioned spherical valve core, and the rotation driving lever that is driven by reduction gear by motor passes in the groove that the valve body cinclides is inserted into the spherical valve core top.
Structure characteristic of the present utility model is to be provided with seal washer at the water outlet place of valve body, simultaneously is provided with a plurality of seal rings again between the lining of water inlet and valve body, realizes double-sealing, good sealing effect.This structure is provided with a plurality of circular holes again in the annular groove of lining, be provided with spring in each circular hole, pressure spring holds equably on removable insole pieces, and removable insole pieces remains nearly with the surface of contact of spherical valve core and contacts like this, good seal performance, this is a kind of dynamic seal (packing) structure.Especially when valve core rotation, because removable insole pieces is subjected to the effect of even elastic force, the friction between spherical valve core and the removable insole pieces is little, rotates flexible, laborsaving.The more important thing is that the spring in the circular hole is evenly to distribute around the lining groove, elastic force is to hold equably on removable insole pieces, when valve core rotation, keeps dynamic seal (packing) between removable insole pieces and the spherical valve core.Owing to be provided with seal ring between the dual-side of removable insole pieces and lining, there is the seal ring isolation in the external world, and spring is located in the circular hole of lining groove, avoids the erosion with water, has prolonged working life.

Fig. 2, the utility model stereochemical structure sectional view;
Fig. 3, stereochemical structure exploded view of the present utility model.
Embodiment
A kind of ball valve that can regulate sealing automatically shown in Fig. 1,2 and 3, include valve body 1, spherical valve core 2, spherical valve core 2 is positioned at valve body 1 inside, there is a through hole 21 centre of spherical valve core 2, the left and right both ends of the surface of valve core through hole are the plane, the cinclides 11 that the turn driving lever 8 that is driven by the reduction gear (not shown) by motor passes valve body 1 is inserted in the groove 22 at spherical valve core 2 tops, realizes the opening and closing to spool 2.
In the water inlet of valve body 1 a circular pipe lining 3 is set, its front end is provided with annular groove 31, is provided with a plurality of uniform circular holes 311 in the groove 31.Be provided with a spring 4 in each circular hole 311, the original length of its medi-spring 4 is greater than hole depth.Between lining 3 and spherical valve core 2 removable insole pieces 5 is set, removable insole pieces 5 is an annulus, and its front-end face is a sphere shape, with spherical valve core 2 are spherical sealings, the rear end is inserted in the groove 31 of lining 3 and with spring 4 and contacts mutually.Lining 3, removable insole pieces 5 are made by plastics or engineering plastics.
Water outlet place at valve body 1 is provided with seal washer 6.Be provided with a pair of " O " shape seal ring 71 between the removable insole pieces 5 of water intake and the dual-side of lining 3 are inside and outside, be provided with 2 " O " shape seal rings 72 between lining 3 and the valve body 1.Both realize double-sealing, good sealing effect.Seal washer 6, " O " shape seal ring 71,72 are made for rubber or tetrachloroethylene material.Owing to be provided with seal ring 71 between the dual-side of removable insole pieces 5 and lining 3, the external world is isolated by seal ring 71, and spring 4 is positioned at the circular hole 311 of lining groove 31, avoids the erosion with water, prevents rust corrosion, has prolonged working life.
The pressure spring 4 that the uniform circular hole that is provided with in lining groove 31 is 311 li holds equably on removable insole pieces 5, like this, in use, removable insole pieces 5 remains close contacting with the surface of contact of spherical valve core 2, good seal performance, reduced spool 2 simultaneously in rotation process and the friction between the removable insole pieces 5, spool 2 is rotated flexibly.After spool 2 local appearance wearing and tearing, the seal clearance that can automatically adjust by the uniform elastic force of spring 4 is close on the spool 2 removable insole pieces 5 all the time, keeps the reliability of ball valve sealing.
In a word, compared with prior art, the utlity model has multi-sealedly, especially it can be automatic Regulate the sealing of removable insole pieces and spherical valve core, guarantee that the dynamic sealing performance of spool is good, and spool turns to Flexibly moving, long service life.
