Description

Technical Field

[0001] This utility model relates to a tool for removing the sleeve of an electric output valve, belonging to the technical field of electric output valve repair tools. Background Technology

[0002] The electric output valve of the high-pressure pump can precisely control the water flow output by the high-pressure pump during production. By adjusting the valve opening, the water flow rate can be controlled, which is crucial for the specific water flow requirements of different stages in the steel rolling process.

[0003] When the electric output valve malfunctions, it severely impacts the steel rolling mill system, consequently affecting production progress and equipment quality. To ensure smooth steel rolling production, any malfunctioning electric output valve must be replaced. However, replacing an electric output valve is not only expensive but also time-consuming. In production practice, it has been found that electric output valve failures primarily involve actuator malfunction, plunger scratches, and valve sleeve seal failure. To save costs and shorten maintenance time, when an electric output valve malfunctions, only the actuator, plunger, and valve sleeve need to be replaced, without replacing the valve body. This significantly reduces production costs and saves maintenance time. However, when replacing the actuator, plunger, and valve sleeve, only the valve sleeve is difficult to remove, sometimes requiring destructive removal, increasing maintenance costs. Therefore, it is essential to design a tool for easily removing the electric output valve sleeve. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a tool for easily removing the valve sleeve of an electric output valve. This tool can quickly and easily remove the valve sleeve, avoid damage to the valve sleeve, improve maintenance efficiency, and reduce spare parts costs.

[0005] The technical solution to the above technical problem is:

[0006] A tool for easily removing the sleeve of an electric output valve includes a crossbeam, pull plates, a mounting pin, and a rotating handle. The crossbeam is made of rectangular steel plate and is placed horizontally. The pull plates are also rectangular steel plates, with their upper ends vertically welded to both sides of the middle of the crossbeam. The surfaces of the two pull plates are parallel and opposite each other, and the lower ends of the two pull plates have shaft holes. The rotating handle is a cuboid steel block, the thickness of which matches the gap between the two pull plates. The rotating handle is placed between the two pull plates, and its middle section has a mounting shaft hole that aligns with the shaft holes of the two pull plates. The mounting pin rotatably connects the rotating handle and the lower ends of the two pull plates through the mounting shaft hole.

[0007] The aforementioned tool for easily removing the sleeve of the electric output valve has a rotating handle whose length matches the outer diameter of the sleeve. The two ends of the rectangular rotating handle are downward arc shapes, and the two ends of the circular shape transition into horizontal plates. The horizontal plates are inserted into the outlet of the sleeve, and the upper surface of the horizontal plates is opposite to the lower surface of the upper crossbar of the outlet of the sleeve.

[0008] The aforementioned tool for easily removing the electric output valve sleeve also includes two jacks. The two jacks are placed on both sides of the valve body above the valve sleeve, and the upper ends of the push rods of the two jacks rest on the lower ends of the crossbeam.

[0009] The beneficial effects of this utility model are:

[0010] In this invention, a crossbeam is placed above the valve sleeve, and two jacks are placed on both sides of the valve body above the valve sleeve. The upper ends of the push rods of the two jacks are placed below the two ends of the crossbeam, and the push rods of the two jacks can lift the crossbeam upward. The two ends of the rotating handle can be inserted into the lower surface of the crossbeam above the outlet of the valve sleeve. When the crossbeam rises, the crossbeam drives the rotating handle to rise through the pull plate and the mounting pin. The two ends of the rotating handle drive the valve sleeve to rise, and the valve sleeve is pulled out of the valve body.

[0011] This utility model has a simple structure and is easy to use. When the electric output valve does not close tightly, it is not necessary to replace the entire valve. The valve sleeve can be quickly and easily removed, avoiding damage to the valve sleeve, improving maintenance efficiency and reducing spare parts costs. Attached Figure Description

[0018] This utility model consists of a crossbeam 1, a pull plate 2, a mounting pin 3, a rotating handle 4, and a jack 5.

[0019] Figure 1 ,2 As shown, beam 1 is a rectangular steel plate, and beam 1 is placed horizontally.

[0020] The pull plate 2 is a rectangular steel plate. The upper ends of the two pull plates 2 are vertically welded to both sides of the middle part of the crossbeam 1. The surfaces of the two pull plates 2 are parallel and opposite to each other. The lower ends of the two pull plates 2 have shaft holes.

[0021] The rotating handle 4 is a rectangular steel block. The thickness of the rectangular handle 4 matches the gap between the two pull plates 2. The rotating handle 4 is placed between the two pull plates 2. The middle part of the rotating handle 4 has a mounting shaft hole that is opposite to the shaft holes of the two pull plates 2. The mounting pin 3 rotatably connects the rotating handle 4 and the lower end of the two pull plates 2 through the mounting shaft hole. The rotating handle 4 can rotate around the mounting pin 3 so that it can be inserted into the valve sleeve 9 through the opening at the upper end of the valve sleeve 9.

[0022] Figure 1 , 2 As shown, the two ends of the cuboid of the rotating handle 4 are downward arc shapes, and the two ends of the circular shape transition to horizontal plates. The horizontal plates can be inserted into the valve sleeve outlet 10. The upper surface of the horizontal plates is opposite to the lower surface of the upper crossbar of the valve sleeve outlet 10. The length of the rotating handle 4 matches the outer diameter of the valve sleeve 9, so that the valve sleeve 9 can be lifted upward through the valve sleeve outlet 10.

[0023] Figure 3 , 4 As shown, when removing the valve sleeve of the electric output valve, two jacks 5 are placed on both sides of the valve body 6 above the valve sleeve 9. The upper ends of the push rods of the two jacks 5 are pressed against the lower ends of the crossbeam 1, and the push rods of the two jacks 5 can lift the crossbeam 1 upward. The two ends of the rotating handle 4 are inserted into the lower surface of the crossbar above the outlet 10 of the valve sleeve. When the crossbeam 1 rises, the crossbeam 1 drives the rotating handle 4 to rise through the pull plate 2 and the mounting pin 3. The rotating handle 4 drives the valve sleeve 9 to rise, and the valve sleeve 9 is removed from the valve body 6.

[0024] The usage process of this utility model is as follows:

[0025] First, after removing the valve's gland, actuator, and plunger, heat the inside of the valve sleeve 9 with an oxy-acetylene torch for 30-40 minutes. After sufficient heating, quickly cool the valve body 6 with prepared fire-fighting water. Once the valve sleeve 9 has cooled to room temperature, use this tool in conjunction with two 100-ton hydraulic jacks 5 to remove the valve sleeve 9. During the removal process, continuously vibrate the valve body 6 by striking it with a sledgehammer.

[0026] When using this tool, please follow these steps:

[0027] First, rotate the rotating handle 4 clockwise by 90°, and then insert the pull plate 2 and the rotating handle 4 into the valve sleeve 9 through the upper opening of the valve sleeve 9.

[0028] The second step is to manually rotate the rotating handle 4 counterclockwise by 90° after it is placed inside the valve sleeve 9, and place the two end plates of the rotating handle 4 into the outlet 10 of the valve sleeve, with the upper surface of the horizontal plate facing the lower surface of the upper crossbar of the outlet 10 of the valve sleeve.

[0029] Third step, after the rotating handle 4 is placed in the valve sleeve outlet 10, the jack 5 above the valve body 6 is raised to a certain height and contacts the crossbeam 1. The jack 5 continues to be raised, and the crossbeam 1 drives the pull plate 2 and the rotating handle 4 to rise together under the action of the jack 5, which in turn drives the valve sleeve 9 to rise, so as to remove the valve sleeve 9.

[0030] The fourth step is to remove the valve sleeve 9, and then replace the plunger, seal, and valve sleeve 9.
