Description

Technical Field

[0001] This utility model relates to a disassembly and assembly tool, and more particularly to a special tool for disassembling and assembling the valve core of a diaphragm regulating valve. Background Technology

[0002] Because the valve core of a control valve is embedded, its installation, disassembly, and adjustment are inconvenient. The valve core is a non-standard part, and currently there is no dedicated tool for disassembling and assembling the valve core of a control valve. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a special tool for disassembling and assembling the valve core of a diaphragm regulating valve, so as to achieve convenient and accurate disassembly and assembly of the valve core.

[0004] This utility model is achieved through the following technical solution:

[0005] A special tool for disassembling and assembling a diaphragm regulating valve core is provided. The valve core of the regulating valve has two arc-shaped protrusions evenly distributed circumferentially at its top. The tool includes a sleeve with an open bottom and a closed top. The bottom of the sleeve has two locking grooves evenly distributed circumferentially, which match the two arc-shaped protrusions of the valve core. The top of the sleeve has an operating groove that cooperates with a wrench. An operating rod is transversely inserted through the upper section of the sleeve. The outer circumferential surface of the sleeve is provided with circumferential scale lines and axial scale lines.

[0006] As a preferred embodiment of the special tool for disassembling and assembling the valve core of the aforementioned diaphragm regulating valve, the operating rod is inserted through two through holes in the upper section of the sleeve, with both ends of the operating rod extending out of the sleeve and threadedly connected to balls.

[0007] As a preferred embodiment of the special tool for disassembling and assembling the valve core of the aforementioned diaphragm regulating valve, the circumferential scale line is an angle scale line, and the axial scale line is a length scale line.

[0008] As a preferred embodiment of the special tool for disassembling and assembling the valve core of the aforementioned diaphragm regulating valve, the operating groove is a square groove.

[0009] This invention has the following advantages over the prior art:

[0010] This utility model provides a special tool for disassembling and assembling the valve core of a diaphragm regulating valve. Two evenly distributed snap-fit ​​grooves along the circumference of the bottom end of the sleeve align with two arc-shaped protrusions on the valve core, achieving precise alignment between the sleeve and the valve core. Tightening the sleeve then rotates the valve core. The sleeve rotation can be achieved using an operating rod or the operating groove in conjunction with a wrench, making the sleeve rotation operation convenient, time-saving, and labor-saving, thus enabling easy disassembly and assembly of the valve core. Furthermore, the circumferential and axial scale lines on the outer circumferential surface of the sleeve allow for direct observation of the valve core's rotation angle and depth during installation, resulting in more precise valve core installation.

[0016] The embodiments of this utility model are described in detail below. These embodiments are implemented based on the technical solution of this utility model and provide detailed implementation methods and specific operation processes. However, the protection scope of this utility model is not limited to the following embodiments.

[0017] See Figures 1 to 4 This embodiment discloses a special tool for disassembling and assembling a diaphragm regulating valve core. The valve core 8 of the regulating valve has two arc-shaped protrusions 9 evenly distributed circumferentially at its top. The tool includes a sleeve 1 with an open bottom and a closed top. The bottom end of the sleeve 1 has two locking grooves 2 evenly distributed circumferentially, which match the two arc-shaped protrusions 9 of the valve core 8. The top end of the sleeve 1 has an operating groove 5 that mates with a wrench. The operating groove 5 is a square groove to facilitate use with a torque wrench or a ratchet wrench to rotate the sleeve 1. An operating rod 3 is transversely inserted through the upper section of the sleeve 1. The operating rod 3 passes through two through holes in the upper section of the sleeve 1. Both ends of the operating rod 3 extend out of the sleeve 1 and are threadedly connected to balls 4. Two balls 4 are provided to prevent the operating rod 3 from coming off the sleeve 1.

[0018] The outer circumferential surface of sleeve 1 is provided with circumferential scale lines 7 and axial scale lines 6. The circumferential scale lines 7 are angle scale lines, which can be designed as multiple vertical lines evenly distributed along the circumference of sleeve 1, with each vertical line indicating the corresponding angle value. The axial scale lines 6 are length scale lines, which can be designed as multiple horizontal lines evenly distributed along the axial direction of sleeve 1, with each horizontal line indicating the corresponding length value.

[0019] In use, based on the structure of the valve core 8, the two locking grooves 2 at the bottom of the sleeve 1 can engage with the two arc-shaped protrusions 9 at the top of the valve core 8. After rotating the sleeve 1 by the operating lever 3, the valve core 8 can be twisted and installed into the valve body of the regulating valve, thus achieving convenient installation of the valve core 8. When disassembling the valve core 8, simply rotate the sleeve 1 in the opposite direction to easily remove the valve core 8. Furthermore, an operating groove 5 is provided at the top of the sleeve 1. During use, a torque wrench or ratchet wrench can be engaged in the operating groove 5 for rotation, providing multiple ways to twist the sleeve 1 and making it convenient to use. In addition, a circumferential scale 7 and an axial scale 6 are provided on the outer circumferential surface of the sleeve 1. During adjustment, the depth of insertion of the valve core 8 can be observed through the axial scale 6, and the circumferential scale 7 can be used to determine the installation depth of the valve core 8 while observing the angle after twisting and installation, thus enabling more accurate determination of the depth. Before disassembly, mark an initial position on the valve body shell so that when installing the corresponding scale line later, screw it to this position, making the disassembly and assembly of valve core 8 more precise.

[0020] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
