Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a valve disassembly device. Background Art

[0002] In today's equipment maintenance and repair work in various industries such as industry, construction, and energy, dismantling operations are a common link. However, most of the existing dismantling tools and methods are highly versatile, but poorly targeted, and are not very effective when faced with specific types of dismantling tasks. Especially in the frequently encountered operation scenario of valve dismantling, the problem is more prominent. At present, the valves that need to be dismantled during maintenance often have complex conditions such as large pipe diameter, severe rust, high temperature at the valve mouth, and large diameter. The existing technology faces many difficulties in dismantling such valves. Common dismantling methods have serious shortcomings. For example, a common way is to use a movable wrench to fix the valve, and at the same time arrange another employee to use a hammer to hit the movable wrench, hoping to loosen the valve through this impact. Another way is to directly knock on the valve with a hammer to achieve the purpose of loosening.

[0003] However, these traditional removal methods have problems that cannot be ignored. From the perspective of work efficiency, since these methods require the collaboration of multiple people, each operation step requires close cooperation, and coordination is difficult in actual operation, resulting in low overall work efficiency and a lot of time wasted on the connection between preparation and operation. During the operation, damage to valves and pipelines is a serious problem. Whether it is directly hitting the valve or transmitting the impact force through an adjustable wrench, the valve and the pipeline connected to it will be subjected to a large external force. This external force can easily cause the valve and pipeline to deform, destroying their original structure and precision. Once deformed, the valve may not be able to close or open normally, and the pipeline may also leak, making these parts unable to continue to be used and can only be discarded as spare parts, resulting in a waste of resources. In summary, the existing valve removal technology needs to be improved to improve efficiency, reduce damage and ensure safety. Summary of the invention

[0004] In order to solve the technical problems existing in the background technology, the present invention provides a valve disassembly device.

[0005] The present invention provides a valve disassembly device, wherein the valve comprises a valve seat, and the valve seat has a first outer side wall and a second outer side wall arranged relatively parallel to each other, comprising:

[0006] A base, the base having a groove body, the groove body having a first inner side wall and a second inner side wall arranged opposite to each other, and a protrusion partially extending outward from one end of the base opposite to the groove body;

[0007] A first abutment portion, when the valve seat is located in the groove body, the first abutment portion can be fixed between the first inner wall and the first outer wall to form a limit position;

[0008] The second abutment portion can be fixed between the second inner wall and the second outer wall to form a limit when the valve seat is located in the groove body.

[0009] Preferably, the valve seat has a first threaded through hole penetrating the first inner side wall, and the first abutment portion extends along its length direction to form a first screw. When the valve seat is located in the groove body, the first screw is screwed into the groove body through the first threaded through hole and abuts against the first inner side wall. The valve seat has a second threaded through hole penetrating the second inner side wall, and the second abutment portion extends along its length direction to form a second screw. When the valve seat is located in the groove body, the second screw is screwed into the groove body through the second threaded through hole and abuts against the second inner side wall, so that the first abutment portion is fixed between the first inner side wall and the first outer side wall to form a limit, and the second abutment portion is fixed between the second inner side wall and the second outer side wall to form a limit.

[0010] Preferably, it also includes a first nut welded on the first inner wall of the valve seat and a second nut welded on the second inner wall of the valve seat, the valve seat having a first threaded through hole penetrating the first inner wall, the first abutment extending along its length direction to form a first screw, the valve seat having a second threaded through hole penetrating the second inner wall, the second abutment extending along its length direction to form a second screw, the first screw is adapted to the first nut, the second screw is adapted to the second nut, the first nut is coaxially arranged with the first threaded through hole, and the second nut is coaxially arranged with the second threaded through hole, when the valve seat is located in the groove body, the first screw is screwed into the first threaded through hole and the first nut in sequence from outside the groove body so that the first abutment is fixed between the first inner wall and the first outer wall to form a limit, the second screw is screwed into the second threaded through hole and the second nut in sequence from outside the groove body to fix the second abutment between the second inner wall and the second outer wall to form a limit.

[0011] Preferably, it also includes a first nut welded on the first inner wall of the valve seat and a second nut welded on the second inner wall of the valve seat, the first screw is adapted to the first nut, and the second screw is adapted to the second nut, the valve seat has a first through hole penetrating the first inner wall, the first abutment extends along its length direction to form the first screw, the valve seat has a second through hole penetrating the second inner wall, the second abutment extends along its length direction to form the second screw, when the valve seat is located in the groove body, the first screw passes through the first through hole and is screwed into the first nut and presses the first nut against the first inner wall so that the first abutment is fixed between the first inner wall and the first outer wall to form a limit; the second screw passes through the second through hole and is screwed into the second nut and presses the second nut against the second inner wall so that the second abutment is fixed between the second inner wall and the second outer wall to form a limit.

[0012] Preferably, an insertion rod is further included, and the protrusion has a slot arranged along its extension direction, and the insertion rod can be adapted to be inserted into the slot.

[0014] The valve disassembly device proposed by the present invention has the advantages that a limit is formed between the outer side walls of the valve seat and the inner side walls of the base groove body by the first abutment part and the second abutment part. Whether the screw is matched with the threaded through hole, or the screw is matched with the welding nut, or the screw passes through the through hole and matches with the nut and tightens the nut, the valve seat can be effectively fixed to prevent displacement, shaking or offset during the disassembly process, thereby providing stable operating conditions for the disassembly work. The coaxial arrangement design in the various preferred schemes makes the force more uniform and improves the reliability of the limit. Moreover, these limit methods can still remain stable when the valve is used for a long time or frequently disassembled, thereby ensuring the performance of the disassembly device. The method of achieving the limit by tightening the nut has a certain flexibility, can adapt to different installation and disassembly situations, and can also compensate for the clearance problem caused by factors such as processing errors to a certain extent, thereby ensuring the limit effect.

[0019] refer to Figure 1-4 The present invention provides a valve disassembly device, the valve comprises a valve seat, the valve seat has a first outer side wall 1 and a second outer side wall 2 arranged relatively parallel to each other, comprising:

[0020] A base 3, the base 3 having a groove 4, the groove 4 having a first inner wall 5 and a second inner wall 6 arranged opposite to each other, and a protrusion 7 partially extending outward from one end of the base 3 opposite to the groove 4;

[0021] A first abutment portion, when the valve seat is located in the groove body 4, the first abutment portion can be fixed between the first inner wall 5 and the first outer wall 1 to form a limit position;

[0022] The second abutment portion can be fixed between the second inner wall 6 and the second outer wall 2 to form a limit when the valve seat is located in the groove body 4 .

[0023] When the valve on the pipeline is disassembled, the valve can be shaken by rotating the protrusion 7, thereby facilitating subsequent disassembly.

[0024] Furthermore, the valve seat has a first threaded through hole 8 passing through the first inner side wall 5, and the first abutment portion extends along its length direction to form a first screw 9. When the valve seat is located in the groove body 4, the first screw 9 is adapted to be screwed into the groove body 4 through the first threaded through hole 8 and abuts against the first inner side wall 5. The valve seat has a second threaded through hole 10 passing through the second inner side wall 6, and the second abutment portion extends along its length direction to form a second screw 11. When the valve seat is located in the groove body 4, the second screw 11 is screwed into the groove body 4 through the second threaded through hole 10 and abuts against the second inner side wall 6, so that the first abutment portion is fixed between the first inner side wall 5 and the first outer side wall 1 to form a limit, and the second abutment portion is fixed between the second inner side wall 6 and the second outer side wall 2 to form a limit.

[0025] For the first abutment portion, when the valve seat is in the groove body 4, the first threaded through hole 8 on the valve seat plays a key role. This first threaded through hole 8 runs through the first inner side wall 5, and the first screw 9 extending from the first abutment portion is adapted thereto. In actual operation, after the valve seat is placed in the groove body 4, the first screw 9 is screwed into the groove body 4 through the first threaded through hole 8. This screwing-in process requires precise operation to ensure that the first screw 9 accurately abuts against the first inner side wall 5 to form a stable limit. This limit mechanism ensures that during the disassembly of the valve, the valve seat will not be displaced in the direction of the first outer side wall 1 and the first inner side wall 5, providing a stable operating environment for subsequent disassembly work.

[0026] Similarly, for the second abutment portion, the valve seat is provided with a second threaded through hole 10 penetrating the second inner side wall 6, and when the valve seat is located in the groove body 4, the second screw 11 extending from the second abutment portion is screwed into the groove body 4 through the second threaded through hole 10 and tightly abuts against the second inner side wall 6. In this way, the second abutment portion forms a reliable limit between the second inner side wall 6 and the second outer side wall 2, and cooperates with the limit function of the first abutment portion, so that the valve seat is firmly fixed in the groove body 4, avoiding unnecessary shaking or deviation when disassembling the valve, and ensuring the smooth disassembly work.

[0027] Furthermore, it also includes a first nut 12 welded on the first inner side wall 5 of the valve seat and a second nut 13 welded on the second inner side wall 6 of the valve seat. The valve seat has a first threaded through hole 8 penetrating the first inner side wall 5, and the first abutment portion extends along its length direction to form a first screw 9. The valve seat has a second threaded through hole 10 penetrating the second inner side wall 6, and the second abutment portion extends along its length direction to form a second screw 11. The first screw 9 is adapted to the first nut 12, and the second screw 11 is adapted to the second nut 13. The first nut 12 is coaxially arranged with the first threaded through hole 8, and the second nut 13 is coaxially arranged with the second threaded through hole 10. When the valve seat is located in the groove body 4, the first screw 9 is screwed into the first threaded through hole 8 and the first nut 12 in sequence from the outside of the groove body 4 so that the first abutment portion is fixed between the first inner side wall 5 and the first outer side wall 1 to form a limit, and the second screw 11 is screwed into the second threaded through hole 10 and the second nut 13 in sequence from the outside of the groove body 4 to fix the second abutment portion between the second inner side wall 6 and the second outer side wall 2 to form a limit.

[0028] For the first abutment, there is a first nut 12 welded on the first inner side wall 5 of the valve seat. The first threaded through hole 8 on the valve seat is still the key element, which runs through the first inner side wall 5. The first screw 9 extending from the first abutment is compatible with the first nut 12, and the first nut 12 and the first threaded through hole 8 are coaxially arranged. When the valve seat is placed in the groove body 4, the first screw 9 is operated from the outside of the groove body 4 to be screwed into the first threaded through hole 8 and the first nut 12 in turn. This coaxial arrangement allows the first screw 9 to be evenly stressed during the screwing process, and can more stably fix the first abutment between the first inner side wall 5 and the first outer side wall 1, forming an accurate and firm limit. This design improves the reliability of the limit, and can also ensure the stability of the limit function of the first abutment in the case of long-term use or frequent disassembly of the valve.

[0029] For the second abutment, similarly, there is a second nut 13 welded on the second inner side wall 6 of the valve seat, the second threaded through hole 10 on the valve seat penetrates the second inner side wall 6, the second screw 11 extending from the second abutment is adapted to the second nut 13, and the second nut 13 is coaxial with the second threaded through hole 10. When the valve seat is located in the groove body 4, the second screw 11 is screwed into the second threaded through hole 10 and the second nut 13 in sequence from the outside of the groove body 4, so that the second abutment is stably fixed between the second inner side wall 6 and the second outer side wall 2 to form a limit. This design effectively enhances the limiting effect of the second abutment, ensures the stability of the valve seat in this direction during the valve disassembly process, and further improves the performance of the entire disassembly device.

[0030] In this case, there may be a certain distance between the first inner wall 5 and the first outer wall 1 , so that valves of different sizes can be used.

[0031] Furthermore, it also includes a first nut 12 welded on the first inner side wall 5 of the valve seat and a second nut 13 welded on the second inner side wall 6 of the valve seat, the first screw 9 is adapted to the first nut 12, and the second screw 11 is adapted to the second nut 13, the valve seat has a first through hole penetrating the first inner side wall 5, and the first abutment portion extends along its length direction to form the first screw 9, the valve seat has a second through hole penetrating the second inner side wall 6, and the second abutment portion extends along its length direction to form the second screw 11, when the valve seat is located in the groove body 4, the first screw 9 passes through the first through hole and is screwed into the first nut 12 and presses the first nut 12 on the first inner side wall 5 so that the first abutment portion is fixed between the first inner side wall 5 and the first outer side wall 1 to form a limit; the second screw 11 passes through the second through hole and is screwed into the second nut 13 and presses the second nut 13 on the second inner side wall 6 to form a limit.

[0032] For the first abutment portion, there is a first nut 12 welded on the first inner side wall 5 of the valve seat. Here, the valve seat is provided with a first through hole penetrating the first inner side wall 5, and the first screw 9 extending from the first abutment portion has a unique operation method. When the valve seat is located in the groove body 4, the first screw 9 passes through the first through hole, and then screws into the first nut 12, and during the screwing-in process, the first nut 12 is pressed against the first inner side wall 5. This pressing action is the key to forming a stable limit, which enables the first abutment portion to be reliably fixed between the first inner side wall 5 and the first outer side wall 1. This method of achieving limit by tightening the nut, while ensuring the limit effect, also has a certain flexibility, can adapt to different installation and disassembly situations, and can compensate to a certain extent for clearance problems that may be caused by factors such as processing errors.

[0033] For the second abutment, there is a second nut 13 welded on the second inner side wall 6 of the valve seat. There is a second through hole on the valve seat that penetrates the second inner side wall 6. When the valve seat is located in the groove body 4, the second screw 11 extending from the second abutment passes through the second through hole and is screwed into the second nut 13, and then the second nut 13 is pressed against the second inner side wall 6, so that the second abutment is fixed between the second inner side wall 6 and the second outer side wall 2 to form a limit. This design ensures that the valve seat is stable in this direction during the valve disassembly process, and this clamping limit method can effectively avoid loosening problems caused by factors such as vibration, providing reliable protection for disassembly work.

[0034] Furthermore, it also includes an insertion rod 14. The protrusion 7 has a slot 15 arranged along its extension direction. The insertion rod 14 can be adapted to be inserted into the slot 15, and the slot 15 is a through slot.

[0035] The insertion rod 14 in the device and the slot 15 on the protrusion 7 also play an important role. The insertion rod 14 can be inserted into the slot 15. During the disassembly operation, the insertion rod 14 can be used as an auxiliary tool. For example, when external force is required for disassembly, the force is transmitted through the insertion rod 14, thereby enhancing the controllability and convenience of the entire disassembly process.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
