Problems solved by technology

[0004] The object of the present invention is to provide a ball valve that can improve the sealing performance to solve the problem that in the actual use of the existing ball valve proposed in the above background technology, due to the relatively high flow pressure of the liquid medium inside the pipe network, and the gap between the ball valve and the pipe network. The stronger the impact stress between the ball valve and the longer the service life of the ball valve, it will directly lead to the worse sealing between the ball valve and the pipe network.

Embodiment 1

[0029] see Figure 1-6 , the present invention provides a technical solution: a ball valve that can improve sealing performance, comprising a valve body 1, a valve cover 2 is fixedly connected to the top of the valve body 1, a handwheel 3 is rotatably connected to the top of the valve cover 2, and the handwheel 3 The bottom of the valve is provided with a valve stem 4 used in conjunction with the valve cover 2, and the bottom of the valve stem 4 is fixedly connected with a spherical valve core 5 used in conjunction with the valve body 1;

[0030]Both sides of the valve body 1 are fixedly connected with mounting flanges 6 by bolts, and the inner cavity of the two sets of mounting flanges 6 is provided with a sealing structure 7. By setting the sealing structure 7, the annular sealing groove 71, the main sealing ring The cooperation of 72 and the auxiliary sealing ring 78 can realize the sealing function of the secondary seal inside the two sets of installation flanges 6, and im...

Embodiment 2

[0032] see Figure 1-6 , the present invention provides a technical solution: a ball valve that can improve sealing performance, comprising a valve body 1, a valve cover 2 is fixedly connected to the top of the valve body 1, a handwheel 3 is rotatably connected to the top of the valve cover 2, and the handwheel 3 The bottom of the valve stem 4 is provided with a valve stem 4 used in conjunction with the valve cover 2, an arc-shaped through groove 15 is opened in the center of the right side of the valve cover 2, and the top of the right side of the valve stem 4 is fixedly connected with the arc-shaped through groove 15. The limit bump 16 can limit the rotation angle of the valve stem 4 to prevent the construction personnel from mishandling the valve stem 4, and also effectively protect the spherical valve core 5. The limit bump 16 is located in the arc-shaped through groove 15. The maximum rotation angle inside the valve is not more than 180°, the bottom of the valve stem 4 is...

Abstract

The ball valve capable of improving the sealing performance comprises a valve body, the top of the valve body is fixedly connected with a valve cover, the top of the valve cover is rotationally connected with a hand wheel, the bottom of the hand wheel is provided with a valve rod used in cooperation with the valve cover, and the bottom of the valve rod is fixedly connected with a spherical valve element used in cooperation with the valve body. By arranging a sealing structure, through cooperation of an annular sealing groove, a main sealing ring and an auxiliary sealing ring, the sealing function of a secondary sealing piece can be achieved in the two sets of mounting flange plates, the compression resistance of the interiors of the two sets of mounting flange plates is improved, and then through cooperation of an elastic ball, an arc-shaped abutting-against base, an elastic cushion, a sliding base and a circular abutting-against head, the sealing effect is improved. The impact stress between the main sealing ring and the auxiliary sealing ring can be elastically counteracted, deformation damage caused by stress between the main sealing ring and the auxiliary sealing ring is avoided, the overall sealing effect in the two sets of installation flange plates is directly enhanced, and therefore the overall installation sealing performance between the two sets of installation flange plates and the water inlet pipe and the water outlet pipe is further improved.

Description

technical field [0001] The invention relates to the technical field of ball valves, in particular to a ball valve capable of improving sealing performance. Background technique [0002] Ball valve: a valve whose opening and closing member (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control, especially for media containing fibers, tiny solid particles, etc., while the ball valve is in the pipeline. It can not only flexibly control the confluence, shunt, and flow direction switching of the medium, but also close any channel and connect the other two channels, and the ball valve should generally be installed horizontally in the pipeline. [0003] When the construction personnel install the pipe network, in order to better control the flow effect of the liquid medium in the pipe network, it is necessary to install the ball valve at the predetermined position of the pipe network. However, in the ac...
