Abstract
The utility model relates to a ball seal valve, which comprises a body, a valve closure arranged on the body, a valve stem arranged on the valve closure and a handle arranged on the valve stem. The utility model is characterized in that: the inner cavity of the valve is a spherical surface; a water inlet and a water outlet are arranged on the spherical surface at the bottom of the inner cavity of the valve body; a sealing wall is connected at the lower end of the valve rod. The utility model has the advantages that: the seal surface at the bottom of the sealing ball has no friction with the sealing surface at bottom of the valve; the sealing ball is wear resistant, thus the service life of the valve is greatly lengthened; in addition, the sealing ball can close the water inlet and the water outlet at the same time, thus the sealing is reliable and the valve is leakage free.
Description
The utility model belongs to a kind of stop valve, particularly a kind of ball sealed valve.
Stop valve of the prior art mainly is made up of valve body, valve gap, sealing gasket, screw rod and handwheel etc.Sealing gasket be positioned at the valve inleting water mouth above, and be installed in the bottom of screw rod, the upper and lower motion by screw rod opens or closes valve.The subject matter that this valve exists is, sealing gasket rotates with screw rod, when the valve open and close and the valve inleting water mouth friction is arranged, sealing gasket weares and teares easily, causes valve to leak.In addition, when valve is in open mode, be full of water in the valve body, this can cause corrosion to valve rod on the one hand, reduces the working life of valve, also leaks easily in the junction of valve rod and valve gap on the other hand.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and existing valve is improved, and the ball sealed valve of a kind of good sealing effect, long service life is provided.
The utility model is achieved in that
It has a valve body, valve gap is housed on the valve body, valve rod is housed on the valve gap, handle is housed on the valve rod, its special way is, the intracavity bottom of valve body is a sphere, and water intake and water outlet are positioned on the sphere of body cavity bottom, lower end at valve rod is connected with ball sealer, utilizes ball sealer to open or seal water intake and water outlet.
Advantage of the present utility model is:
1, during the open and close valve, the sealing surface of ball sealer bottom does not have friction with the sealing surface of body cavity bottom, and ball sealer is not easy damage, thereby has prolonged the working life of valve.
2, during valve closing, ball sealer can be closed water intake and water outlet simultaneously, good sealing effect, and sealing is reliable, has guaranteed that valve can not leak.
3, during valve open, the sidewall Elastic Contact of ball sealer and body cavity, with the top seal of valve body, thereby the screw thread place that valve gap top is combined with valve rod is water-tight.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Provide embodiment of the present utility model below in conjunction with accompanying drawing:
As shown in drawings, the utility model has a valve body 8, and valve body 8 adopts metal or plastic production; Valve gap 4 is housed on valve body 8, between valve gap 4 and the valve body 8 for being threaded, and sealing mutually between the two; Valve rod 3 is housed on valve gap 4, adopts between valve rod 3 and the valve gap 4 to be threaded, make valve rod 3 that axially fortune take place when rotated; Handle 2 is housed on valve rod 3, and rotatable handle 2 can make screw rod 3 realize upper and lower motion, and is fixing with nut 1 between handle 2 and the screw rod 3; The intracavity bottom of described valve body 8 is a sphere, and water intake and water outlet are positioned on the sphere of valve body 8 intracavity bottoms, are connected with ball sealer 7 in the lower end of valve rod 3, ball sealer 7 adopts rubber to make, reliable to guarantee sealing, an inner core 6 is arranged in ball sealer 7, inner core 6 is fixed together with ball sealer 7; A nut 5 is arranged in the lower end of screw rod 3, screw rod 3 and inner core 6 are linked together, thereby when realizing screw rod 3 rotations, inner core 6 and ball sealer 7 be not with its rotation, only with the purpose of its upper and lower motion, and in the process of ball sealer 7 upper and lower motions, open or close water intake and water outlet, realize the purpose of valve open and close, ball sealing configuration of the present utility model also can be used for water tap.
