[0001] The utility model relates to the technical field of butterfly valves, in particular to a disassembly and assembly tool. Background Art

[0002] The wafer-type butterfly valve is a regulating valve with a simple structure, which is mainly used for the on-off control of low-pressure pipeline media.

[0003] Currently, when disassembling and assembling a wafer-type butterfly valve, it is usually necessary to use a sledgehammer to hit the wafer-type butterfly valve. However, this working method is not only time-consuming and labor-intensive, but also poses certain safety risks. Utility Model Content

[0004] In view of this, the utility model provides a disassembly and assembly tool to solve the problem that the solution for disassembling and assembling the wafer-type butterfly valve in the related art is time-consuming, labor-intensive and has safety hazards.

[0005] The utility model provides a disassembly and assembly tool for disassembling a wafer-type butterfly valve, wherein the wafer-type butterfly valve comprises a valve plate, a sealing ring and a valve body which are sequentially sleeved, wherein the sealing ring, the valve plate and the valve body are provided with a coaxial through hole, and a valve plate shaft is passed through the through hole, comprising:

[0006] A mounting seat, the upper surface of which is used to mount and fix the wafer-type butterfly valve and leaves a gap with the wafer-type butterfly valve, wherein the gap is greater than the thickness of the wafer-type butterfly valve;

[0007] A supporting frame is provided on the mounting seat;

[0008] a first telescopic member, disposed on the support frame, wherein the telescopic end of the first telescopic member is used to drive the valve plate to move along the thickness direction of the wafer-type butterfly valve;

[0009] The second telescopic member is arranged on one side of the mounting seat, and the telescopic end of the second telescopic member is used to drive the valve plate shaft to move along its axial direction.

[0010] Beneficial effect: The utility model utilizes the telescopic movement of the first telescopic member and the second telescopic member to disassemble and assemble the clamp-type butterfly valve, which can not only reduce the labor intensity of the operator and the time consumed in the disassembly and assembly process, but also reduce the possibility of injury to the operator.

[0011] In an optional embodiment, the support frame includes at least two oppositely arranged support rods and a support beam, and the support beam is arranged at one end of the two support rods away from the mounting seat; the first telescopic member is arranged on the support beam.

[0012] Beneficial effect: The utility model enables the support frame to form a relatively solid structure through the cooperation of two support rods and the support beam. After the first telescopic member is installed on the support beam, the telescopic end of the support beam can be smoothly extended and retracted in the thickness direction of the clamp-type butterfly valve, thereby smoothly completing the disassembly and assembly operation of the valve plate.

[0013] In an optional embodiment, there are multiple first telescopic members, and the multiple first telescopic members are arranged at intervals along the length direction of the support beam.

[0014] Beneficial Effects: The utility model arranges multiple first telescopic members at intervals along the length of the support beam, which can increase the number of stress points on the valve plate during assembly and disassembly, shortening the time it takes for the valve plate to fall off the valve body or to be assembled onto the valve body. Furthermore, the provision of multiple first telescopic members can prevent the valve plate from being subjected to stress at a single point, improve the uniformity of stress on the valve plate, and reduce the probability of damage to the valve plate during assembly and disassembly.

[0015] In an optional embodiment, the first telescopic member is slidably connected to the support beam, and the sliding direction of the first telescopic member is consistent with the length direction of the support beam.

[0016] Beneficial effect: By utilizing the sliding of the first telescopic member along the length direction of the support beam, the operator can flexibly adjust the relative position relationship between the telescopic member and the valve plate according to the type of the clamp-type butterfly valve, thereby improving the versatility and adaptability of the disassembly and assembly tooling.

[0017] In an optional embodiment, a pressure plate is further included, one side of the pressure plate is used to abut against the telescopic end of the first telescopic member, and the other side is used to abut against the sealing ring, and the diameter of the pressure plate is smaller than the inner diameter of the valve body.

[0018] Beneficial effect: Since the sealing ring is sleeved outside the valve plate, the telescopic end of the first telescopic member cannot directly abut against the sealing ring. In order to solve the above problem and avoid the operator using a sledgehammer to disassemble and assemble the sealing ring, the utility model sets a pressure plate between the telescopic end of the first telescopic member and the sealing ring, which can increase the contact area between the sealing ring and the first telescopic member, and ensure that the force generated by the first telescopic member can be evenly and effectively transmitted to the sealing ring. In this way, not only is the tedious operation of the operator using a sledgehammer to disassemble and assemble the sealing ring avoided, but the efficiency and safety of disassembling and installing the sealing ring are also improved. In addition, the design of the pressure plate having a diameter smaller than the inner diameter of the valve body can not only prevent the pressure plate from interfering with the valve body during the disassembly and assembly of the sealing ring, thereby reducing the possibility of damage to the clamp-type butterfly valve, but also improve the safety during the disassembly and assembly process.

[0019] In an optional embodiment, the mounting seat is provided with a pair of oppositely arranged limiting columns, and a space for mounting the valve body is formed between the pair of limiting columns.

[0020] Beneficial effects: The utility model arranges the valve body between a pair of oppositely arranged limit columns, which can ensure that the relative position of the valve body and the mounting seat remains fixed during the disassembly and assembly process, thereby improving the reliability of the disassembly and assembly tooling.

[0021] In an optional embodiment, the limiting column includes at least two sub-columns, and the at least two sub-columns are arranged at intervals along the circumference of the valve body.

[0022] Beneficial effect: The multiple sub-columns of the utility model are arranged at intervals along the circumference of the valve body, which can increase the contact area between the limiting column and the valve body and improve the limiting effect of the limiting column on the valve body.

[0023] In an optional embodiment, the mounting seat includes a first sub-mounting seat and a second sub-mounting seat, the first sub-mounting seat is used to install and fix the clamp-type butterfly valve; the second sub-mounting seat is arranged on one side of the first sub-mounting seat and is provided with a sliding groove extending axially along the valve plate axis, and the second telescopic member is slidably connected to the second telescopic member through the sliding groove.

[0024] Beneficial effects: The mounting seat of the utility model is composed of a first sub-mounting seat and a second sub-mounting seat, which means that there is no need to equip the second telescopic part with an additional fixing seat, thereby making the structure of the entire tooling more compact. Secondly, compared with equipping the second telescopic part with an independent fixing seat, arranging the second telescopic part on the second sub-mounting seat can reduce the number of accessories of the tooling and improve the convenience of carrying and sorting and maintenance. Furthermore, a slide groove slidably connected to the second telescopic part is provided on the second sub-mounting seat, so that the operator can adjust the relative position of the second telescopic part and the clamp-type butterfly valve according to actual needs, thereby enabling the disassembly and assembly tooling of the utility model to disassemble and assemble different types of clamp-type butterfly valves, thereby improving the adaptability and versatility of the disassembly and assembly tooling.

[0025] In an optional embodiment, the groove wall of the slide groove is provided with a plurality of first positioning holes, and the plurality of first positioning holes extend along the axial direction of the valve plate axis and are spaced apart; the fixed end of the second telescopic member is provided with a second positioning hole corresponding to the through hole, and the second telescopic member is connected to the second sub-mounting seat by a positioning pin passing through the second positioning hole and any one of the first positioning holes.

[0026] Beneficial Effects: Multiple first positioning holes are designed into the chute wall, allowing operators to select the appropriate first positioning hole based on specific needs, thereby flexibly adjusting the relative position between the second telescopic member and the valve body. This design allows the disassembly and assembly tool to accommodate wafer-type butterfly valves of various sizes and shapes, significantly improving the tool's versatility and adaptability. Furthermore, the use of a locating pin to connect the second telescopic member to the second submount simplifies the installation and disassembly steps, effectively improving work efficiency.

[0027] In an optional embodiment, two pins are arranged opposite to each other. When the valve plate is disassembled, the two pins are inserted into the through holes of the sealing ring and the valve body.

[0028] Beneficial effect: The utility model utilizes a pin shaft to fix the sealing ring, mainly to protect the sealing ring from damage and prevent it from shifting when the valve plate is disassembled, thereby ensuring that the sealing performance of the wafer-type butterfly valve is not affected during the disassembly and reinstallation process.

[0033] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0034] Aiming at the problem that the solution of disassembling and assembling the wafer-type butterfly valve in the related art is time-consuming, labor-intensive and has potential safety hazards, the utility model provides a disassembly and assembly tool.

[0035] The following combination Figure 1 , describing the embodiments of the present utility model.

[0036] The current wafer-type butterfly valve generally includes a valve plate, a sealing ring and a valve body which are sequentially sleeved. The sealing ring, the valve plate and the valve body are provided with a coaxial through hole, and the valve plate shaft is passed through the through hole.

[0037] In order to complete the disassembly and assembly of the wafer-type butterfly valve conveniently and quickly, according to the embodiment of the present utility model, Figure 1 As shown, a disassembly and assembly tool is provided, including: a mounting seat 1, a support frame 2, a first telescopic member 3 and a second telescopic member 4.

[0038] Specifically, the upper surface of the mounting seat 1 is used to install and fix the wafer-type butterfly valve and leaves a gap with the wafer-type butterfly valve, and the gap is greater than the thickness of the wafer-type butterfly valve; the support frame 2 is arranged on the mounting seat 1; the first telescopic member 3 is arranged on the support frame 2, and the telescopic end of the first telescopic member 3 is used to drive the valve plate to move along the thickness direction of the wafer-type butterfly valve; the second telescopic member 4 is arranged on one side of the mounting seat 1, and the telescopic end of the second telescopic member 4 is used to drive the valve plate axis to move along its axial direction.

[0039] This embodiment utilizes the telescopic movement of the first telescopic member 3 and the second telescopic member 4 to disassemble and assemble the wafer-type butterfly valve, which can not only reduce the labor intensity of the operator and the time consumed in the disassembly and assembly process, but also reduce the possibility of injury to the operator.

[0040] It should be noted that, in this embodiment, the first telescopic member 3 and the second telescopic member 4 can be one of a jack, a telescopic oil cylinder and a telescopic air cylinder.

[0041] According to one embodiment of the present invention, Figure 1 As shown, the support frame 2 includes at least two opposing support rods 201 and a support beam 202. The support beam 202 is disposed at one end of the two support rods 201 away from the mounting base 1. The first telescopic member 3 is disposed on the support beam 202. In this embodiment, the cooperation between the two support rods 201 and the support beam 202 enables the support frame 2 to form a relatively solid structure. After the first telescopic member 3 is mounted on the support beam 202, the telescopic end of the support beam 202 can smoothly extend and retract in the thickness direction of the wafer-type butterfly valve, thereby smoothly completing the valve plate disassembly and assembly operation.

[0042] According to one embodiment of the present invention, the first telescopic member 3 is slidably connected to the support beam 202, and the sliding direction of the first telescopic member 3 is consistent with the length direction of the support beam 202. By utilizing the sliding of the first telescopic member 3 along the length direction of the support beam 202, the operator can flexibly adjust the relative position of the telescopic member and the valve plate according to the type of wafer-type butterfly valve, thereby improving the versatility and adaptability of the assembly and disassembly tooling.

[0043] According to one embodiment of the present invention, Figure 1 As shown, there are multiple first telescopic members 3, and the multiple first telescopic members 3 are spaced apart along the length of the support beam 202. In this embodiment, the multiple first telescopic members 3 are spaced apart along the length of the support beam 202, which can increase the force points on the valve plate during the disassembly and assembly process, shortening the time it takes for the valve plate to fall off the valve body or shortening the time it takes to assemble the valve plate to the valve body. Secondly, the provision of multiple first telescopic members 3 can avoid single-point force on the valve plate, improve the uniformity of force on the valve plate, and reduce the probability of damage to the valve plate during disassembly and assembly.

[0044] It should be noted that the length direction of the support beam 202 in this embodiment is Figure 1 The direction shown in is consistent.

[0045] According to one embodiment of the present invention, a pressing plate is further included, one side of the pressing plate being used to abut the telescopic end of the first telescopic member 3, and the other side being used to abut the sealing ring, and the diameter of the pressing plate is smaller than the inner diameter of the valve body. It is understandable that because the sealing ring is sleeved outside the valve plate, the telescopic end of the first telescopic member 3 cannot directly abut the sealing ring. In order to solve the above problem and avoid the operator using a sledgehammer to disassemble and assemble the sealing ring, this embodiment provides a pressing plate between the telescopic end of the first telescopic member 3 and the sealing ring. This can increase the contact area between the sealing ring and the first telescopic member 3, ensuring that the force generated by the first telescopic member 3 can be evenly and effectively transmitted to the sealing ring. In this way, not only does the operator avoid the tedious operation of using a sledgehammer to disassemble and assemble the sealing ring, but it also improves the efficiency and safety of disassembling and installing the sealing ring. In addition, the design of the pressing plate having a diameter smaller than the inner diameter of the valve body not only prevents the pressing plate from interfering with the valve body during the disassembly and assembly of the sealing ring, reducing the possibility of damage to the wafer-type butterfly valve, but also improves the safety during the disassembly and assembly process.

[0046] According to one embodiment of the present invention, Figure 1 As shown, the mounting base 1 is provided with a pair of opposed limiting posts 1011, with a space for mounting the valve body formed between the pair of limiting posts 1011. In this embodiment, the valve body is disposed between the pair of opposed limiting posts 1011, ensuring that the relative position of the valve body and the mounting base 1 remains fixed during assembly and disassembly, thereby improving the reliability of the assembly and disassembly tooling.

[0047] According to one embodiment of the present invention, at least one limiting post 1011 is slidably connected to the mounting base 1, and the sliding direction of the limiting post 1011 is consistent with the radial direction of the valve body. By utilizing the radial sliding of the limiting post 1011 along the valve body, the operator can flexibly adjust the distance between the pair of limiting posts 1011 according to the size of the wafer-type butterfly valve, thereby improving the versatility and adaptability of the assembly and disassembly tooling.

[0048] According to one embodiment of the present invention, Figure 1 As shown, the limiting pillar 1011 includes at least two sub-pillars, which are spaced apart along the circumference of the valve body. In this embodiment, the multiple sub-pillars are spaced apart along the circumference of the valve body to increase the contact area between the limiting pillar 1011 and the valve body, thereby improving the limiting effect of the limiting pillar 1011 on the valve body.

[0049] According to one embodiment of the present invention, Figure 1 As shown, the mounting base 1 includes a first sub-mounting base 101 and a second sub-mounting base 102. The first sub-mounting base 101 is used to install and fix the clamp-type butterfly valve; the second sub-mounting base 102 is arranged on one side of the first sub-mounting base 101 and is provided with a slide groove 1021 extending axially along the valve plate axis, and the second telescopic member 4 is slidably connected to the second telescopic member 4 through the slide groove 1021. The mounting base 1 of this embodiment is composed of the first sub-mounting base 101 and the second sub-mounting base 102, which means that there is no need to additionally equip the second telescopic member 4 with a fixed base, thereby making the structure of the entire tooling more compact. Secondly, compared to equipping the second telescopic member 4 with an independent fixed base, arranging the second telescopic member 4 on the second sub-mounting base 102 can reduce the number of accessories of the tooling and improve the convenience of carrying, sorting and maintenance. Furthermore, a sliding groove 1021 is provided on the second sub-mounting seat 102, which is slidingly connected to the second telescopic member 4, so that the operator can adjust the relative position of the second telescopic member 4 and the clamp-type butterfly valve according to actual needs, thereby enabling the disassembly and assembly tool of this embodiment to disassemble and assemble different types of clamp-type butterfly valves, thereby improving the adaptability and versatility of the disassembly and assembly tool.

[0050] According to one embodiment of the present invention, Figure 1As shown, the groove wall of the slide 1021 is provided with a plurality of first positioning holes 1022, and the plurality of first positioning holes 1022 extend along the axial direction of the valve plate axis and are spaced apart; the fixed end of the second telescopic member 4 is provided with a second positioning hole corresponding to the through hole, and the second telescopic member 4 is connected to the second sub-mounting seat 102 by a positioning pin passing through the second positioning hole and any first positioning hole 1022. A plurality of first positioning holes 1022 are designed on the groove wall of the slide 1021, so that the operator can select the appropriate first positioning hole 1022 according to specific needs, thereby flexibly adjusting the relative position between the second telescopic member 4 and the valve body. This design enables the disassembly and assembly tooling to adapt to various sizes and shapes of clamp-type butterfly valves, significantly improving the versatility and adaptability of the tooling. In addition, the second telescopic member 4 is connected to the second sub-mounting seat 102 by a positioning pin, which simplifies the installation and disassembly steps between the two and effectively improves work efficiency.

[0051] According to one embodiment of the present invention, two opposing pins are provided. When the valve plate is removed and assembled, the two pins are inserted into the through-holes of the sealing ring and the valve body. This embodiment utilizes the pins to secure the sealing ring, primarily to protect it from damage and displacement during valve plate removal, thereby ensuring that the sealing performance of the wafer-type butterfly valve is not affected during removal and reassembly.

[0052] Although the embodiments of the present invention have been described with reference to the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations shall fall within the scope defined by the appended claims.
