Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a valve body that facilitates the addition of lubricant. Background Technology

[0002] In the field of valve technology, friction and wear between the valve shaft and the valve body has long been a technical challenge. Traditional lubrication methods rely on manual, periodic addition of lubricant, which is cumbersome and results in uneven lubrication. Although there are automatic lubrication structures in existing technologies, they generally suffer from drawbacks such as complex structures, high maintenance costs, and insufficient sealing. For example, some valves use fixed oil filling holes, which can lead to lubricant leakage due to gravity.

[0003] Therefore, it is necessary to provide a new valve body that facilitates the addition of lubricant to solve the above-mentioned technical problems. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a valve body that facilitates the addition of lubricant.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 5 This utility model provides a valve body that facilitates the addition of lubricant. The valve body includes a valve body 1 and an oil reservoir 5. A rotatably connected shaft column 2 is inserted into a shaft cavity 1a inside the valve body 1, and a rotating disk 3 is fixedly installed on the top of the shaft column 2. An annular cavity 1d is provided on the valve body 1, and the annular cavity 1d is coaxially arranged with the shaft cavity 1a and surrounds the outside of the shaft cavity 1a. The annular cavity 1d communicates with the shaft cavity 1a through a number of annularly distributed guide holes 1e.

[0027] In the embodiments of this utility model, please refer to Figures 1 to 5 The lower surface of the rotating disk 3 is fixedly welded with an arc-shaped protruding abutment block 4 for abutting the oil storage cylinder 5 to slide down. The valve body 1 is provided with an insertion hole 1b, and the bottom of the insertion hole 1b is provided with an injection hole 1c that communicates with the annular cavity 1d. The oil storage cylinder 5 is installed on the valve body 1 with elastic connection. Specifically, the cylinder of the oil storage cylinder 5 near the bottom is inserted into the insertion hole 1b and slidably connected to the insertion hole 1b. A docking spring 8 is fixedly installed on the lower surface of the oil storage cylinder 5, and the other end of the docking spring 8 is fixedly connected to the inner bottom wall of the insertion hole 1b.

[0028] The valve body 1 is equipped with an elastically connected oil reservoir 5, and a filling pipe 51 is fixedly installed at the bottom of the oil reservoir 5. A sealing element 53 is installed inside the filling pipe 51. The sealing element 53 includes a steel ball 531 and a mounting bracket 533. The steel ball 531 is slidably installed inside the filling pipe 51, and a sliding rod 532 is fixedly installed on the upper spherical surface of the steel ball 531. The mounting bracket 533 is fixedly installed on the inner wall of the filling pipe 51. The rod head of the sliding rod 532 passes through the mounting bracket 533 and is slidably connected to the mounting bracket 533. A return spring 534 is sleeved on the sliding rod 532. The return spring 534 drives the steel ball 531 to block the oil outlet at the bottom of the filling pipe 51. One end of the return spring 534 is fixedly connected to the upper spherical surface of the steel ball 531, and the other end of the return spring 534 is fixedly connected to the lower surface of the mounting bracket 533.

[0029] A ball-pressing rod 6 is installed inside the injection hole 1c. A bracket 61 is fixedly installed at the bottom of the ball-pressing rod 6, and the bracket 61 is fixedly installed inside the injection hole 1c.

[0030] It should be noted that when the arc-shaped protrusion on the rotating disk 3 does not abut against the oil reservoir 5, the steel ball 531 blocks the oil outlet at the bottom of the filling pipe 51 under the action of the return spring 534, and the filling pipe 51 at the bottom of the oil reservoir 5 also slides out of the injection hole 1c under the elastic force of the docking spring 8. At this time, the pressure rod 6 does not act on the steel ball 531, so the oil reservoir 5 does not add lubricant to the shaft 2 on the valve body 1.

[0031] When the valve is opened, the arc-shaped protrusion abutment block 4 on the rotating disk 3 is deflected to the oil reservoir 5. Under the action of the protrusion of the arc-shaped protrusion abutment block 4, the oil reservoir 5 slides down along the insertion hole 1b and compresses the docking spring 8. At the same time, the filling tube 51 is inserted into the injection hole 1c. Therefore, the ball pressure rod 6 slides into the filling tube 51 from the bottom opening of the filling tube 51 and pushes the steel ball 531 upward. Thus, the steel ball 531 slides up along the mounting bracket 533 through the sliding rod 532 and compresses the return spring 534. At this time, the steel ball 531 is no longer sealing the bottom opening of the filling tube 51. Therefore, the lubricant can enter the injection hole 1c and then be diverted to the shaft cavity 1a by the guide hole 1e on the annular cavity 1d, thereby effectively lubricating the shaft column 2.

[0032] When the arc-shaped protrusion on the rotating disk 3 abuts the block 4 away from the oil reservoir 5, the filling pipe 51 at the bottom of the oil reservoir 5 also slides out of the injection hole 1c under the elastic force of the docking spring 8. As a result, the pressure rod 6 does not act on the steel ball 531, so that the steel ball 531 blocks the oil outlet at the bottom of the filling pipe 51 under the action of the return spring 534. Thus, the oil reservoir 5 cannot add lubricant to the shaft 2 on the valve body 1.

[0033] In this application, through the linkage design of the arc-shaped protrusion abutment block 4 of the rotating disk 3 and the oil reservoir 5, the lubrication action is synchronized with the valve opening and closing. Lubricating oil is added with each operation, eliminating the need for staff to perform additional lubrication work separately, which significantly improves operating efficiency. The sealing element 53 adopts a combination structure of steel ball 531 and return spring 534 to ensure that the oil reservoir 5 is completely sealed when not filled with oil, avoiding lubricant leakage. The oil reservoir 5 achieves elastic return through the docking spring 8. Combined with the limiting effect of the limiting ring 7 and the fixing frame 71, the movement stability of the oil reservoir 5 is ensured, avoiding the risk of tilting.

[0034] The surrounding arrangement of the annular cavity 1d and the guide hole 1e allows the lubricant to be evenly dispersed into the shaft cavity 1a through the guide hole 1e, covering the friction surface of the shaft column 2 and reducing local wear.

[0035] Long-term friction may cause the steel ball 531 seal to fail. Therefore, wear-resistant materials (such as tungsten carbide coating) can be coated on the end of the pressure rod 6 or the surface of the steel ball 531, or ceramic parts can be used to improve durability. Regular maintenance and inspection by staff are also required.

[0036] Furthermore, the oil reservoir 5 is provided with a liquid inlet 52, and a sealing cap is installed on the liquid inlet 52 to facilitate the addition of lubricant to the oil reservoir 5.

[0037] Furthermore, a fixing bracket 71 is fixedly installed on the valve body 1, and a limiting ring 7 is fixedly installed on the fixing bracket 71. When the oil reservoir 5 is not filled with oil into the annular cavity 1d, the top of the oil reservoir 5 abuts against the limiting ring 7. The limiting ring 7 is set so that when the arc-shaped protrusion abutting block 4 does not abut against the oil reservoir 5, it can limit the maximum height of the oil reservoir 5 under the elastic force of the docking spring 8. At the same time, the limiting ring 7, together with the fixing bracket 71, can improve the stability of the oil reservoir 5 and avoid the risk of the oil reservoir 5 tilting when the arc-shaped protrusion abutting block 4 contacts the oil reservoir 5.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
