Description

Technical Field

[0001] The utility model relates to the technical field of ball valves, in particular to a high-reliability ball valve. Background Art

[0002] The ball valve's opening and closing parts (balls) are driven by the valve stem and rotate around the ball valve axis. They can also be used for fluid regulation and control. The hard-sealed V-type ball valve has a strong shear force between its V-shaped ball core and the metal valve seat welded with cemented carbide. It is particularly suitable for media containing fibers, tiny solid particles, etc. The multi-way ball valve can not only flexibly control the confluence, diversion, and flow direction switching of the media in the pipeline, but also close any channel and connect the other two channels. This type of valve should generally be installed horizontally in the pipeline. Ball valves are divided into: pneumatic ball valves, electric ball valves, and manual ball valves according to the drive mode.

[0003] Existing related technologies often have the following defects: in the actual use of the ball valve, it is often connected to the pipeline by a threaded connection. When the connection between the pipeline and the ball valve is only based on the threaded connection, the stability of the connection between the pipeline and the ball valve is low and cannot meet the user's usage needs.

[0004] Therefore, the utility model provides a ball valve with high reliability. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcoming in the prior art that the connection between the pipeline and the ball valve only relies on the threaded connection method and cannot meet the needs of users, and to propose a high-reliability ball valve.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a high-reliability ball valve, comprising a valve body and a handle, the valve body and the handle being rotatably connected, the surface of the valve body being provided with a stabilizing structure, the stabilizing structure comprising four fixed plates fixedly connected to the surface of the valve body in groups of two, the interiors of the two fixed plates being slidably connected to a sliding frame, the ends of the two sliding frames close to each other being fixedly connected to a clamping block, the surface of the valve body being fixedly connected to a second mounting block, the interior of the second mounting block being slidably connected to a sliding pin, the end side of the sliding pin being fixedly connected to a driving frame, the driving frame being located on the outside of the valve body, the side wall of the valve body being fixedly mounted with a first mounting block, the internal thread of the first mounting block being connected to a screw, the screw and the internal rotatable connection of the driving frame.

[0007] The effect achieved by the above components is: by setting a stable structure, it facilitates further stabilization work after the pipe and the valve body are connected, thereby avoiding shaking or loosening between the valve body and the pipe, and improving the stability and reliability of the ball valve.

[0008] Preferably, a plurality of convex strips are fixedly connected to the inner side of the clamping block.

[0009] The effects achieved by the above components are as follows: the provision of the convex strips increases the friction force of the clamping block clamping the pipe, thereby improving the stability of the connection between the pipe and the valve body.

[0010] Preferably, the end side of the sliding frame is rotatably connected to a roller.

[0011] The effects achieved by the above components are as follows: the provision of the rollers reduces the frictional force during relative movement between the driving frame and the sliding frame, thereby facilitating the driving of the sliding frame inside the fixed plate.

[0012] Preferably, a shielding structure is provided on the surface of the valve body, and the shielding structure includes a fixing ring fixedly connected to the surface of the valve body, the outer side of the fixing ring is rotatably connected to a swivel, and the inner thread of the swivel is connected to a bolt.

[0013] The effect achieved by the above components is that the flexibility of controlling the handle is improved by providing the flexibly extendable bolt.

[0014] Preferably, the side wall of the rotating ring is slidably connected to an insert frame, and the side wall of the fixed ring is evenly provided with a plurality of slots.

[0015] The effect achieved by the above components is that the inserting frame is inserted into the inner side of the corresponding slot on the fixed ring, and the locking work between the rotating ring and the fixed ring can be realized after rotation.

[0016] Preferably, the internal thread of the rotating ring is connected to a driving rod, and the driving rod is rotatably connected to the interior of the insertion frame.

[0017] The effect achieved by the above components is: when the driving rod is rotated, the driving rod will push the insertion frame to insert into the inner side of the corresponding slot on the fixing ring.

[0018] In summary:

[0019] 1. In the utility model, after the valve body is connected to the pipeline by means of a threaded connection, the screw is rotated, and the screw pushes the drive frame to move. The sliding pin slides inside the second mounting block to limit the moving direction of the drive frame. At this time, the two slide frames can be driven toward each other at the same time. By setting a stable structure, further stabilization work after the pipeline and the valve body are connected is facilitated, thereby avoiding shaking or loosening between the valve body and the pipeline, and improving the stability and reliability of the ball valve.

[0020] 2. In the utility model, when it is necessary to control the opening angle of the handle on the valve body, first rotate the swivel on the outside of the fixed ring, rotate and extend the bolt on the swivel, and then rotate the drive rod. The drive rod will push the insert frame to insert into the inner side of the corresponding slot on the fixed ring, so that the locking work between the swivel and the fixed ring after rotation can be realized, thereby improving the flexibility of controlling the handle. By setting a shielding structure, the flexible shielding work of the handle rotation position is facilitated, thereby facilitating the control of the handle opening angle, and further facilitating the control of the liquid flow rate in the valve body.

DETAILED DESCRIPTION

[0026] Reference Figure 1 As shown, the utility model provides a technical solution: a high-reliability ball valve, comprising a valve body 1 and a handle 2, the valve body 1 and the handle 2 are rotatably connected, the surface of the valve body 1 is provided with a stabilizing structure 3, and the surface of the valve body 1 is provided with a shielding structure 4.

[0027] The following describes in detail the specific settings and functions of the stabilizing structure 3 and the shielding structure 4.

[0028] Reference Figure 1-Figure 3As shown, in this embodiment, the stabilizing structure 3 includes four fixed plates 305 fixedly connected to the surface of the valve body 1, arranged in groups of two. Each fixed plate 305 has a sliding frame 306 slidably connected to its interior. A clamping block 301 is fixedly connected to the adjacent ends of the two sliding frames 306. A second mounting block 307 is fixedly connected to the surface of the valve body 1. A sliding pin 308 is slidably connected to the interior of the second mounting block 307. The end of the sliding pin 308 is fixedly connected to the drive frame 302, which is located on the outside of the valve body 1. A first mounting block 303 is fixedly mounted on the sidewall of the valve body 1. A screw 304 is threadedly connected to the interior of the first mounting block 303. The screw 304 is internally rotatably connected to the drive frame 302. The provision of the stabilizing structure 3 facilitates further stabilization of the connection between the pipeline and the valve body 1 after docking, thereby preventing any shaking or loosening between the valve body 1 and the pipeline and improving the stability and reliability of the ball valve. Several ridges 309 are fixedly connected to the interior of the clamping block 301. The provision of the ridges 309 increases the frictional force of the clamping block 301 gripping the pipe, thereby improving the stability of the connection between the pipe and the valve body 1. The end of the sliding frame 306 is rotatably connected to a roller 310. The provision of the roller 310 reduces the frictional force during relative motion between the drive frame 302 and the sliding frame 306, facilitating the driving of the sliding frame 306 within the fixed plate 305.

[0029] Reference Figure 1-Figure 2 and Figure 4 As shown, specifically, the shielding structure 4 includes a fixed ring 41 fixedly connected to the surface of the valve body 1, and the outer side of the fixed ring 41 is rotatably connected to a swivel 42, and the internal thread of the swivel 42 is connected to a bolt 43. By providing a flexibly extendable bolt 43, the flexibility of controlling the handle 2 is improved. The side wall of the swivel 42 is slidably connected to an insert frame 44, and the side wall of the fixed ring 41 is evenly provided with a plurality of slots 46. The insert frame 44 is inserted into the inner side of the corresponding slot 46 on the fixed ring 41, and the locking operation between the swivel 42 and the fixed ring 41 after rotation can be realized. The internal thread of the swivel 42 is connected to a drive rod 45, and the drive rod 45 is rotatably connected to the inside of the insert frame 44. When the drive rod 45 is rotated, the drive rod 45 will push the insert frame 44 to insert into the inner side of the corresponding slot 46 on the fixed ring 41.

[0030] Working principle: After the valve body 1 is connected to the pipeline by threaded connection, the screw 304 is rotated, and the screw 304 will push the drive frame 302 to move. The sliding pin 308 slides inside the second mounting block 307 to limit the moving direction of the drive frame 302. At this time, the two slide frames 306 can be driven to move closer to each other at the same time. The setting of the roller 310 reduces the friction between the drive frame 302 and the slide frame 306 when the relative movement occurs, which facilitates the sliding frame 306 to move closer to the fixed plate 305. The driving frame 302 will simultaneously drive the two sliding frames 306 to gather together towards each other, and the clamping block 301 will be stably attached to the side wall of the pipe. The setting of the ridge 309 increases the friction force of the clamping block 301 clamping the pipe, thereby improving the stability of the connection between the pipe and the valve body 1. By setting the stabilizing structure 3, it is convenient to further stabilize the pipe and the valve body 1 after docking, thereby avoiding shaking or loosening between the valve body 1 and the pipe, and improving the stability and reliability of the ball valve.

[0031] When it is necessary to control the opening angle of the handle 2 on the valve body 1, first rotate the swivel ring 42 on the outside of the fixed ring 41, and after the bolt 43 on the swivel ring 42 is rotated and extended, rotate the driving rod 45. The driving rod 45 will push the insertion frame 44 to insert into the inner side of the corresponding slot 46 on the fixed ring 41, so as to realize the locking work between the swivel ring 42 and the fixed ring 41 after rotation. When the personnel is rotating the handle 2, the bolt 43 can block the handle 2 from continuing to rotate, thereby facilitating the control of the rotation angle of the handle 2. By setting the flexibly extendable bolt 43, the flexibility of controlling the handle 2 is improved. By setting the shielding structure 4, the flexible shielding work of the rotation position of the handle 2 is facilitated, thereby facilitating the control of the opening angle of the handle 2, and further facilitating the control of the liquid circulation speed in the valve body 1.

For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.
