Description

Technical Field

[0001] This utility model relates to the field of ball valve device technology, and in particular to an adjustable positioning mechanism and a ball valve device. Background Technology

[0002] A ball valve is a type of valve commonly used in pipeline systems. It controls fluid flow by rotating a perforated ball. It has a simple structure, consisting of a valve body, a ball, a stem, and a sealing ring. It provides good sealing performance and reduces leakage. Ball valves are easy to operate, requiring only a 90-degree rotation to open and close. They have low fluid resistance and are suitable for rapid flow control.

[0003] An investigation revealed that a valve ball switch positioning mechanism (publication number: CN217207998U) is disclosed in Chinese Utility Model Information, comprising a valve body, a valve stem for transmission with a sealing mechanism inside the valve body, a pressure cap, a handle, a locking plate, and a positioning bolt. The pressure cap is installed at the center of the top of the valve body. The locking plate and the handle are both fixedly installed on the valve stem. The positioning bolt is screwed onto the valve body. A locking bolt is screwed onto the locking plate. The valve body is provided with a locking threaded hole corresponding to the locking bolt, and the locking bolt is screwed into the locking threaded hole.

[0004] While the aforementioned patents can improve positioning performance, facilitate disassembly and replacement, and have a locking function, reducing limitations and improving practicality, they can only lock in the fully open or fully closed position and cannot lock in any position. In the process of fine flow adjustment, this will lead to insufficient control precision, poor operational flexibility, and easy waste of resources. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that ball valves can only be locked in the fully open or fully closed position and cannot be locked in any position, resulting in insufficient control precision and poor operational flexibility during fine flow adjustment, and easily causing resource waste, this utility model is proposed.

[0007] Therefore, the purpose of this utility model is to provide an adjustable positioning mechanism.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable positioning mechanism, comprising,

[0009] Valve body;

[0010] The valve core is disposed on the valve body;

[0011] The valve stem is mounted on the valve core;

[0012] An angle-holding assembly includes a positioning element and a locking element, wherein the positioning element is disposed on the valve stem and the locking element is disposed on the positioning element;

[0013] A detachable assembly includes a drive member and a snap-fit ​​member, the drive member being disposed on a valve stem, and the snap-fit ​​member being disposed on the valve stem and the drive member; and an axial compensation assembly disposed on the valve body.

[0014] As a preferred embodiment of the adjustable positioning mechanism of this utility model, the valve stem is provided with a snap-fit ​​groove.

[0019] In a preferred embodiment of the adjustable positioning mechanism of this utility model, the axial compensation component includes an extension tube disposed on the valve body, a ball valve cover disposed on the extension tube, a connecting bolt disposed on the ball valve cover, a rubber pad disposed on the connecting bolt, and a fixing nut disposed on the connecting bolt.

[0020] The beneficial effects of this adjustable positioning mechanism are as follows: By using a positioning plate, positioning bolt, fastening nut, and locking plate, the positioning plate rotates when the handle is turned. The positioning bolt slides inside the opening hole on the locking plate. When the handle rotates the positioning bolt to any desired position, the threaded fastening nut, combined with the positioning plate, secures and clamps the locking plate, thus fixing the rotational position of the positioning plate and locking the valve core's rotational position. This device allows the valve body to be in any open or closed state, enabling various flow control methods, improving control accuracy, providing high operational flexibility, and avoiding resource waste.

[0021] In actual use, there is still a sealing problem between the valve body and the valve core in the above technical solution.

This device allows the valve body 1 to be in any open or closed state, so as to realize multiple control of flow, improve control accuracy, have high operational flexibility, and avoid waste of resources.

[0041] Example 2

[0042] Reference Figure 1 - Figure 3 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an adjustable positioning mechanism, including a detachable component 5, including a driving member 51 and a snap-fit ​​member 52. The driving member 51 is disposed on the valve stem 3, and the snap-fit ​​member 52 is disposed on the valve stem 3 and the driving member 51; and an axial compensation component 6 disposed on the valve body 1.

[0043] Specifically, the drive component 51 includes a connector 511 disposed on the valve stem 3, a handle 512 disposed on the connector 511, and a positioning nut 513 disposed on the connector 511.

[0044] Furthermore, the snap-fit ​​component 52 includes a snap-fit ​​groove 31 disposed on the valve stem 3 and a snap-fit ​​block 521 between the handle 512.

[0045] Furthermore, the axial compensation assembly 6 includes an extension tube 61 disposed on the valve body 1, a ball valve cover 62 disposed on the extension tube 61, a connecting bolt 63 disposed on the ball valve cover 62, a rubber pad 64 disposed on the connecting bolt 63, and a fixing nut 65 disposed on the connecting bolt 63.

[0046] The remaining structure is the same as that in Example 1.

[0047] Operation process: A connector 511 is fixedly connected to the upper surface of the valve stem 3. A handle 512 is slidably connected to the middle of the outer surface of the connector 511. A positioning nut 513 is threadedly connected to the top of the outer surface of the connector 511. The handle 512 is sleeved on the outer surface of the connector 511, and the positioning nut 513 is then tightened to secure the handle 512 to the connector 511. This facilitates the rotation of the valve core 2 via the handle 512, and also makes it easy to disassemble and replace the handle 512. A locking block 521 is fixedly connected to the lower surface of the handle 512. The inner side of the locking block 521 engages with the locking groove 31 on the outer surface of the valve stem 3, allowing the locking block 521 to engage with the valve stem 3, thus facilitating the application of rotational force to the valve stem 3.

[0048] When the handle 512 is rotated, it will drive the positioning plate 411 to rotate. The positioning bolt 412 slides inside the opening hole 423 on the locking plate 422. When the handle 512 drives the positioning bolt 412 to rotate to any desired position, the threaded fastening nut 421, together with the positioning plate 411, can fasten and clamp the locking plate 422, thereby fixing the rotation position of the positioning plate 411 and locking the rotation position of the valve core 2.

[0049] An extension tube 61 is fixedly connected to the upper surface of the valve body 1. A ball valve cover 62 is fixedly connected to the top end of the extension tube 61.

[0054] The remaining structure is the same as that in Example 2.

[0055] Operation process: First, the positioning plate 411, locking plate 422 and handle 512 are sequentially fitted onto the outer surface of the valve stem 3 and connector 511, and then the positioning nut 513 is tightened to fix them. At this time, the locking block 521 is rotated and connected to the middle of the locking plate 422 with the top of the valve stem 3. Next, the connecting bolt 63 is sequentially passed through the ball valve cover 62, rubber gasket 64 and locking plate 422, and then the threaded fixing nut 65 is tightened to connect them. Next, the positioning plate 411 is rotated by the handle 512, and the positioning bolt 412 slides inside the opening hole 423 on the locking plate 422. Finally, when the positioning bolt 412 is rotated to any desired position by the handle 512, the threaded fixing nut 421 is tightened and the positioning plate 411 is tightened to clamp the locking plate 422, thereby fixing the rotation position of the positioning plate 411 and locking the rotation position of the valve core 2.
