Abstract

The utility model discloses a multifunctional ball valve with a replaceable joint, which comprises parts such as a valve body (1), a valve seat (2), a valve cover (3), a valve ball (4), a valve rod (5), a handle (6) and the like. The multifunctional ball valve is mainly characterized by further comprising a loose joint screw nut (7) and a joint (8); the joint (8) is sleeved onto the valve cover (3) through the loose joint screw nut (7); the bore diameter of an outer end opening of the loose joint screw nut (7) is slightly smaller than the diameter of a screw thread of the loose joint screw nut (7); a connecting end of the joint (8) is a convex circular ring; and an O-shaped sealing ring (9) is embedded on a connecting end surface of the valve cover (3) and the loose joint screw nut (7). The ball valve can be connected with various connecting tubes by adding the loose joint screw nut and the joint, and the compatibility of the ball valve is improved. As the O-shaped sealing ring is embedded on the connecting end surface of the valve cover and the loose joint screw nut, the tightness of the ball valve is increased.

Description

The multi-functional ball valve that has replaceable joint
Technical field
The utility model relates to valve field, is a kind of multi-functional ball valve that has replaceable joint specifically.
Background technique
Mainly by component such as valve body, valve gap, valve seat, valve ball, valve rod, handles, valve ball is positioned at valve body to the ball valve of prior art, and valve rod passes valve body, inserts in it on groove of valve ball, and valve ball and valve rod are linked; Be provided with valve seat between valve body inboard and the valve ball; One side of valve body is equipped with valve gap, with fixed valve ball.Simple in structure, easy to operate, the good airproof performance of ball valve all have a wide range of applications in industry and civil area.And the used joint of prior art all is to be fixed on the ball valve when producing, and the connection of two end interfaces of ball valve (scyewed joint, welding etc.) mode is identical, ball valve compatible relatively poor that so just causes prior art, a kind of ball valve just can only be connected with a kind of pipe singlely, and two ends also must be used with a kind of connecting tube.If can improve the compatibility of ball valve better, must bring to ball valve and utilize the space widely.
The model utility content
The technical problems to be solved in the utility model is that the multi-functional ball valve that has replaceable joint of the compatible multiple connecting tube of a kind of energy is provided.
Technical solution of the present utility model is, a kind of multi-functional ball valve that has replaceable joint with following structure is provided, comprise component such as valve body, valve seat, valve gap, valve ball, valve rod, handle, valve ball is positioned at valve body, valve rod passes valve body, insert in it on groove of valve ball, valve ball and valve rod are linked; Be provided with valve seat between valve body inboard and the valve ball, an end of valve body adopts scyewed joint that valve gap is arranged, and handle is fixed on the valve rod by nut.It also comprises loose joint nut and joint, and described joint is connected on the valve gap by the loose joint nut sleeve, and the external port aperture of described loose joint nut is more smaller than its diameter of thread, and the connecting end of described joint is the evagination annulus.
After adopting above structure, the multi-functional ball valve that has a replaceable joint described in the utility model compared with prior art has the following advantages: owing on prior art, increase loose joint nut and joint, ball valve can be connected with multiple adapter, improve the compatibility of ball valve.
As improvement, be embedded with O-ring seals on the end face in valve gap and being connected of loose joint nut, so just increased the sealing of ball valve.
Description of drawings
Accompanying drawing is the structural representation that the utility model has the multi-functional ball valve of replaceable joint.
As shown in the figure 1, valve body, 2, valve seat, 3, valve gap, 4, valve ball, 5, valve rod, 6, handle, 7, the loose joint nut, 8, joint, 9, O-ring seals.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The multi-functional ball valve that has replaceable joint of the present utility model, comprise component such as valve body 1, valve seat 2, valve gap 3, valve ball 4, valve rod 5, handle 6, valve ball 4 is positioned at valve body 1, and valve rod 5 passes valve body 1, insert in it on groove of valve ball 4, valve ball 4 and valve rod 5 are linked; Be provided with valve seat 2 between valve body 1 inboard and the valve ball 4, an end of valve body 1 adopts scyewed joint that valve gap 3 is arranged, and handle 6 is fixed on the valve rod 5 by nut, more than is part same as the prior art.
The characteristics that the multi-functional ball valve that has replaceable joint of the present utility model has are, it also comprises loose joint nut 7 and joint 8, described joint 8 is socketed on the valve gap 3 by loose joint nut 7, the external port aperture of described loose joint nut 7 is more smaller than its diameter of thread, and the connecting end of described joint 8 is the evagination annulus; The external diameter of the evagination annulus of the connecting end of described joint 8 is consistent with the external diameter of valve gap 3, and the interior caliber of joint 8 and the external diameter of externally connected pipe match; Described valve gap 3 is embedded with O-ring seals 9 with being connected of loose joint nut 7 on the end face; Described joint 8 can be threaded joint, welded joint, also can be plastic joint, hose coupling.
Ball valve described in the utility model can select corresponding joint to link with it according to the type and the model of connecting tube when linking to each other with connecting tube.
