[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides an embodiment of a disassembly tooling for balancing valve plate bushings, comprising a main support 1, a valve body 12, and a valve plate bushing body 13. A screw 2 is internally connected to the main support 1, and a positioning nut 7 is threaded onto the outer wall of the screw 2. A support plate 3 is rotatably connected to the outer wall of the screw 2. A notch 8 is formed on the outer wall of the support plate 3. A round pin 9 is fixedly connected internally to the support plate 3. A lifting arm 10 is rotatably connected to the outer wall of the round pin 9. The outer wall of the lifting arm 10 is connected to the inner wall of the notch 8, and a pin is fixedly connected internally to the lifting arm 10. 11. The outer wall of the valve plate bushing 13 is slidably connected to the inner wall of the valve body 12. The inner wall of the valve plate bushing 13 is provided with a fixing hole 14. The outer wall of the pin 11 is slidably connected to the inner wall of the fixing hole 14. An adjustment component is provided on the outer wall of the screw 2. The adjustment component includes an adjustment nut 4. The inner wall of the adjustment nut 4 is threadedly connected to the outer wall of the screw 2. A handle 5 is fixedly connected to the outer wall of the adjustment nut 4. A plane bearing 6 is fixedly connected to the bottom end of the adjustment nut 4. The bottom end of the plane bearing 6 is fixedly connected to the upper surface of the main bracket 1.

[0027] Specifically, the adjusting nut 4 is used to raise and lower the screw 2 while it is rotating. The adjusting nut 4 can also fix the handle 5, which provides a convenient point for applying force. The flat bearing 6 is used to limit the adjusting nut 4, ensuring that the adjusting nut 4 can only rotate and cannot move with the screw 2. The positioning nut 7 can limit the support plate 3, which can fix the round pin 9. The boom 10 can fix the pin 11.

[0028] Reference Figure 4 The lower surface of the main support 1 is in contact with the upper surface of the valve body 12.

[0029] Specifically, when using it, first install the main bracket 1 into the channel opening of the valve body 12. At this time, the lower surface of the main bracket 1 is in contact with the upper surface of the valve body 12.

[0030] Reference Figure 1 The main support 1 is U-shaped; the boom 10 is rectangular.

[0031] Specifically, the main support 1 is U-shaped, and the boom 10 is rectangular, which is simple in structure and easy to manufacture.

[0032] Reference Figure 2 The outer diameter of pin 11 is smaller than the inner diameter of fixing hole 14.

[0033] Specifically, the outer diameter of the pin 11 is smaller than the inner diameter of the fixing hole 14 to ensure that the pin 11 can be smoothly inserted into the inner wall of the fixing hole 14.

[0034] Reference Figure 1 There are two notches 8, which are symmetrically opened on both sides of the outer wall of the support plate 3; there are two round pins 9, which are symmetrically fixedly connected to the inside of the support plate 3.

[0035] Specifically, the notch 8 allows the boom 10 to move within a certain range, and during the descent of the support plate 3, the two booms 10 can be held to prevent them from damaging the inner hole of the valve plate bushing body 13.

[0036] Reference Figure 1 There are two handles 5, which are symmetrically fixed to the outer wall of the adjusting nut 4; a ball is fixedly connected to the end of the handle 5 away from the adjusting nut 4.

[0037] Specifically, handle 5 provides a convenient point for the operator to apply force. By holding handle 5 and turning it, the adjusting nut 4 can be easily rotated. The ball design on handle 5 conforms to ergonomic principles, which can better fit the shape of the human hand and increase the comfort and stability of the grip.

[0038] Working principle: When using, first install the main bracket 1 into the channel of the valve body 12, then rotate the handle 5 to rotate the adjusting nut 4, which in turn rotates the screw 2 and drives the support plate 3 downward. During this process, hold the two lifting arms 10 to prevent them from damaging the inner hole of the valve plate bushing 13. By moving the support plate 3 downward, the pin 11 on the lifting arm 10 is inserted into the inner wall of the fixing hole 14 opened in the inner wall of the valve plate bushing 13. Then, slide the pin 11 into the inner wall of the fixing hole 14 through the lifting arm 10. Then, slowly rotate the handle 5 in the opposite direction to rotate the screw 2 and drive the support plate 3 upward, so that the valve plate bushing 13 can be pulled out from the channel of the valve body 12. After the valve plate bushing 13 is separated from the channel of the valve body 12, remove the tool and remove the valve plate bushing 13. The disassembly is completed without damaging the bushing or the valve body 12, which can ensure the integrity and reusability of the parts, which helps to extend the service life of the parts and reduce costs.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
