Description

Technical Field

[0001] This utility model relates to the field of oil valve technology, specifically an oil valve with an easy-to-disassemble handwheel. Background Technology

[0002] Valves are essential control components in fluid transport systems, used to control fluid flow, including opening, closing, and regulating flow rate and pressure. They are widely used in various industrial, construction, agricultural, and chemical fields to ensure that fluids flow in pipeline systems according to predetermined requirements.

[0003] In petrochemical enterprises, system upgrades or modifications may be necessary due to changes in production demands. This may involve the disassembly and reinstallation of valve handwheels, a crucial step in valve maintenance and repair. Disassembling the handwheel allows for the inspection, cleaning, and replacement of necessary parts within the valve's internal structure, ensuring proper valve operation and extending its lifespan. Currently, handwheels are typically installed using multiple bolts and nuts. Disassembly requires removing these bolts and nuts first, then removing the handwheel, and vice versa. This process is time-consuming and cumbersome. Utility Model Content

[0004] The purpose of this invention is to provide an oil valve with an easy-to-disassemble handwheel, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-5 This utility model discloses an oil valve with an easily detachable handwheel, comprising a valve pipe 1 and a handwheel body 2. The valve pipe 1 is the valve's pipeline, and the handwheel body 2 is the easily detachable handwheel. The valve pipe 1 includes a hexagonal valve core 11 at its top, and a valve stem 21 at the bottom of the handwheel body 2. The valve stem 21 is a connecting structure of the handwheel body 2, and a hexagonal connecting groove 22 is provided at the bottom of the valve stem 21. The hexagonal connecting groove 22 is detachable from the hexagonal valve core 11, that is, the hexagonal valve core 11 is connected through the hexagonal connecting groove 22, so that the hexagonal valve core 11 can be rotated by rotating the handwheel body 2. A connecting sleeve 12 is provided on the outside of the hexagonal valve core 11, and the connecting sleeve 12 is fixedly installed on the top of the valve pipe 1. An mounting plate 23 is provided on the outside of the valve stem 21, and the mounting plate 23 is fixedly installed on the outside of the valve stem 21.

[0026] A mounting sleeve 3 is provided above the connecting sleeve 12. The mounting sleeve 3 is an installation structure. An annular groove 13 is provided on the outer side of the connecting sleeve 12, and a retaining ring 31 is provided on the inner side of the bottom of the mounting sleeve 3. The retaining ring 31 is movably installed in the annular groove 13, that is, the retaining ring 31 is locked in the annular groove 13 and rotates, thereby allowing the mounting sleeve 3 to rotate above the connecting sleeve 12. A shaft groove 14 is provided at the top of the connecting sleeve 12 and inside the mounting sleeve 3. A ball bearing 15 is provided inside the shaft groove 14. Under normal conditions, the upper mounting sleeve 3 is supported by the ball bearing 15, and there is also a certain distance between the outer side of the connecting sleeve 12 and the mounting sleeve 3. Therefore, when the mounting sleeve 3 rotates, the ball bearing 15 supports the upper mounting sleeve 3 in the shaft groove 14. 4. Rolling on top reduces wear on the mounting sleeve 3, thus extending its service life. The mounting sleeve 3 is provided with a connection port 32 and a fixing groove 33 on its upper part. The bottom of the mounting plate 23 is provided with a connecting rod 24 and a fixing block 25. The connecting rod 24 is installed and removed in the connection port 32, and the fixing block 25 is installed and removed in the fixing groove 33. When installing the handwheel body 2, the connecting rod 24 and the fixing block 25 at the bottom of the mounting plate 23 are respectively aligned with the connection port 32 and the fixing groove 33 and inserted. After inserting a certain distance, the hexagonal connection groove 22 at the bottom may not be aligned. That is, the alignment can be completed by slightly rotating the handwheel body 2 and the mounting sleeve 3.

[0027] A fixing component is provided on one side of the fixing groove 33. The fixing component is used to fix the handwheel body 2. The fixing component includes a sliding groove 34, and a slider 44 is provided inside the sliding groove 34. The slider 44 is slidably connected to the sliding groove 34. A latch 41 is provided on the slider 44. A bayonet 42 is provided on one side of the fixing block 25. The latch 41 is installed and removed in the bayonet 42. A threaded opening 35 is provided on the outside of the sliding groove 34. A bolt 4 is provided inside the threaded opening 35. The bolt 4 is threadedly connected to the threaded opening 35. A movable pin 45 is provided on the bolt 4. A movable opening 43 is provided on the inside of the slider 44. 5 is movably connected to the movable port 43, that is, the movable bolt 45 is locked in the movable port 43 and rotates. After the fixed block 25 is installed, the bolt 4 rotates in the screw hole 35 and the movable bolt 45 rotates in the movable port 43, thereby pushing the inner slider 44. That is, by inserting the latch 41 into the bayonet 42, the fixing is completed. Conversely, only the bolt 4 needs to be screwed outward, which will drive the slider 44 and the latch 41 to slide into the sliding groove 34. The latch 41 is removed in the bayonet 42, so that the handwheel body 2 can be pulled directly upward. Both disassembly and assembly are relatively convenient.

[0028] The working principle of this utility model is as follows: When installing the handwheel body 2, the connecting rod 24 at the bottom of the mounting plate 23 and the fixing block 25 are respectively connected to the connection port 32 and the fixing groove 33 and inserted. After inserting a certain distance, the hexagonal connection groove 22 at the bottom may not be connected. Simply rotate the handwheel body 2 and the mounting sleeve 3 slightly to complete the connection, so that the hexagonal connection groove 22 connects to the hexagonal valve core 11. After the fixing block 25 is installed, the bolt 4 is rotated in the screw hole 35 and the movable bolt 45 is rotated in the movable hole 43, thereby pushing the inner slider 44. That is, by inserting the retaining bolt 41 into the retaining hole 42, the fixing is completed. Conversely, simply unscrew the bolt 4 outward, which will drive the slider 44 and the retaining bolt 41 to slide into the sliding groove 34. The retaining bolt 41 is disassembled in the retaining hole 42, so that the handwheel body 2 can be pulled out directly upward. The disassembly and assembly are relatively convenient. The ball bearing 15 rolls on the shaft groove 14, thereby reducing the wear of the mounting sleeve 3 and extending its service life.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
