Description

Technical Field

[0001] This utility model relates to the field of cylinder head valve technology, and in particular to a simple cylinder head valve seat removal tool. Background Technology

[0002] The valve head is a key component of a valve, usually referring to the core structural part of the valve that directly controls the flow of fluid or regulates it. Its specific form and function vary depending on the type of valve. Large and medium-sized diesel engines are composed of multiple cylinders, and each cylinder head has multiple exhaust valves. The exhaust valve seat needs to be cooled by high-temperature water. When the seal between the exhaust valve seat and the cylinder head is damaged, water leakage will occur at that point, causing the unit to malfunction and requiring the valve head to be removed.

[0003] However, special tools are required for valve seat removal, which are inconvenient to carry. This necessitates welding an old, matching valve stem onto the valve seat for forced removal, wasting a valve seat each time. Therefore, this invention proposes a simple cylinder head valve seat removal tool. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0020] like Figure 1 and Figure 4 As shown, this utility model proposes a simple cylinder head valve seat removal tool, including a fitting assembly. The fitting assembly includes a pull rod 1, with a first thread 2 on the outside of the pull rod 1 near one end. An adjusting nut 3 is rotatably connected to the outside of the first thread 2, and the adjusting nut 3 can move outside the first thread 2. A flat washer 4 is fixedly connected to one side of the adjusting nut 3, and a conical block 5 is provided on the side of the flat washer 4 away from the adjusting nut 3. The conical block 5 is fixedly connected to the outside of the pull rod 1, and the flat washer 4 can adjust the position of the conical block 5 on the side of the adjusting nut 3. A lifting assembly is provided on the outside of the pull rod 1 away from the first thread 2. A protective support assembly is provided on the outside of the pull rod 1 near the lifting assembly, and the protective support assembly is used to protect the conical block 5 and support the lifting assembly. An extension assembly is provided between the protective support assembly and the adjusting nut 3, and the extension assembly is used to fix the distance between the lifting assembly and the protective support assembly.

[0021] For further details, please refer to Figure 1 , Figure 2 and Figure 4 The lifting assembly includes a hollow jack 8, which can apply a pulling force to the center position. The hollow jack 8 is located outside the pull rod 1 away from the first thread 2. The hollow jack 8 can pull the pull rod 1 along its interior. A second thread 6 is provided on the outside of the pull rod 1 near the hollow jack 8. A fastening nut 7 is rotatably connected to the outside of the second thread 6. The fastening nut 7 can move along the outside of the second thread 6, thereby allowing the fastening nut 7 to adjust the position of the hollow jack 8.

[0022] For further details, please refer to Figures 1 to 4 The protective support assembly includes a support cover 9, which is slidably connected to the outside of the pull rod 1. The support cover 9 can move outside the pull rod 1. The inside of the support cover 9 is hollow. The open side of the support cover 9 is located outside the pull rod 1 near the first thread 2. The support cover 9 can protect the conical block 5. The side of the support cover 9 away from the open side is located at the bottom of the hollow jack 8. The support cover 9 can support the hollow jack 8.

[0023] For further details, please refer to Figures 1 to 3 The extension component includes a threaded sleeve 10, which is slidably connected to the outside of the pull rod 1. The threaded sleeve 10 can be fitted between the hollow jack 8 and the support cover 9. An adjusting sleeve 11 is rotatably connected to the outside of the threaded sleeve 10. The adjusting sleeve 11 can adjust its length along the position of the threaded sleeve 10 to provide support between the hollow jack 8 and the support cover 9. A limiting block 12 is fixedly connected to the outside of the threaded sleeve 10 away from the adjusting sleeve 11. The limiting block 12 can restrict the adjusting sleeve 11. A pushing block 13 is fixedly connected to the outside of the adjusting sleeve 11 away from the threaded sleeve 10. The pushing block 13 can increase the contact support area.

[0024] In this embodiment, when removing the valve seat, a conical block 5 is placed on the outside of the valve seat. Since the valve seat height is different, the adjusting nut 3 can be rotated outside the first thread 2, so that the adjusting nut 3 drives the flat washer 4 and squeezes the conical block 5 to embed the conical block 5 inside the valve seat. The conical block 5 can fit tightly with the valve seat, and then the valve seat can be removed by using the pulling force of the conical block 5.

[0025] When removing the valve seat, the hollow jack 8 can be used to move the pull rod 1. To prevent the hollow jack 8 from detaching from the pull rod 1, the fastening nut 7 is rotated outside the second thread 6 to adjust the pressure on the position of the hollow jack 8. This allows the hollow jack 8 to pull the pull rod 1 to lift the conical block 5 and the valve seat.

[0026] When applying force with the hollow jack 8, the support cover 9 can be fastened to the conical block 5 to facilitate the application of force with the hollow jack 8. If the height of the valve seat is different, the distance between the hollow jack 8 and the support cover 9 needs to be adjusted so that the hollow jack 8 can move the pull rod 1 for a longer distance. At this time, the support cover 9, the hollow jack 8 and the fastening nut 7 can be removed from the outside of the pull rod 1.

[0027] Then remove the threaded sleeve 10 and the adjusting sleeve 11, and then put the support cover 9 on the outside of the pull rod 1, so that the threaded sleeve 10 and the adjusting sleeve 11 can be put on the outside of the pull rod 1. This allows the threaded sleeve 10 and the adjusting sleeve 11 to support the hollow jack 8. Then, use the fastening nut 7 to rotate outside the second thread 6 to adjust and stabilize the hollow jack 8. At this time, the hollow jack 8 can apply a pulling force to the pull rod 1, thereby allowing the pull rod 1 to drive the conical block 5 to move.

[0028] When the hollow jack 8 needs to be adjusted to different heights, the adjusting sleeve 11 can be rotated to extend outside the threaded sleeve 10. The limiting block 12 and the pushing block 13 can prevent the adjusting sleeve 11 from detaching from the threaded sleeve 10. The limiting block 12 and the pushing block 13 can increase the contact surface between the hollow jack 8 and the support cover 9.

[0029] It should be noted that this device uses a conical block 5 inserted into the valve seat. The expansion of the conical block 5 is adjusted by adjusting the nut 3 to fit the inside of the valve seat. At this time, the hollow jack 8 can drive the pull rod 1 to move under the support of the support cover 9. In this way, the pull rod 1 can drive the conical block 5 to remove the valve seat, which facilitates the removal of the valve seat and reduces the cost of removing the valve seat.

[0030] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
