Description

Technical Field

[0001] The present application belongs to the technical field of regulating valve disassembly and assembly, and specifically relates to an auxiliary tooling for regulating valve disassembly and assembly. Background Art

[0002] Pneumatic control valves are usually combined instruments formed by connecting, installing and debugging a pneumatic actuator and a valve body. They are mainly used to control the flow, pressure and temperature of fluids (liquid or gas) in industries such as industry, chemical industry, electric power, food, pharmaceuticals, and environmental protection. They have the advantages of simple control, fast response, and safety, and do not require additional explosion-proof measures.

[0003] When assembling a pneumatic control valve, the valve body and the pneumatic actuator are usually assembled first, and then the pneumatic actuator is assembled to the valve body. Since most of the parts of the pneumatic control valve are made of metal materials, the weight of the pneumatic actuator is relatively large, and since the bottom end face of the valve body is an arc surface, it is more difficult to assemble the pneumatic actuator on the valve body, so it requires multiple disassembly and assembly personnel to assemble it. Moreover, due to the large number of disassembly and assembly personnel, the disassembly and assembly personnel's vision is blocked, affecting the assembly efficiency of the pneumatic control valve. In addition, since the pneumatic control valve is usually made of iron materials, after the pneumatic control valve is used for a period of time, the flange on the pneumatic actuator will rust together with the flange on the valve body, which makes it more difficult to disassemble the pneumatic control valve. Utility Model Content

[0004] The present application provides an auxiliary tool for disassembling and assembling a regulating valve, so as to reduce the difficulty of disassembling and assembling a pneumatic regulating valve and improve the efficiency of disassembling and assembling a pneumatic regulating valve.

[0005] The technical solution adopted in this application is:

[0006] An auxiliary tooling for disassembling and assembling a regulating valve comprises a disassembly plate and a lifting assembly, wherein the lifting assembly comprises two clamping rods for clamping and fixing a pneumatic actuator and a driving member arranged on the disassembly plate, wherein the driving member is used to drive the clamping rods to move in a vertical direction so that the two clamping rods drive the pneumatic actuator to move in a vertical direction.

[0007] By adopting the above technical solution, when the pneumatic actuator is assembled on the valve body, the driving member is first started so that the driving member drives the clamping rod upward, and then the valve body is placed under the clamping rod. The two clamping rods are then used to clamp and fix the pneumatic actuator, so that the pneumatic actuator is in a suspended state and is located directly above the valve body. The driving member is then started so that the driving member is under the clamping rod, so that the pneumatic actuator falls directly above the valve body, and then the pneumatic actuator is fixed to complete the assembly of the pneumatic control valve. In this process, the number of people required for disassembly and assembly is reduced, thereby reducing the assembly cost of the pneumatic control valve and avoiding the situation where a large number of disassembly and assembly personnel affect the viewing angle, thereby improving the assembly efficiency of the pneumatic control valve.

[0008] When inspecting the pneumatic control valve, first use the clamping rod to clamp and fix the pneumatic actuator, then remove the bolts fixing the pneumatic actuator, and then start the drive part, so that the clamping rod drives the pneumatic actuator to move upward. If the flange of the pneumatic actuator and the flange of the valve body are rusted together, the valve body or the pneumatic actuator can be knocked at this time to separate the pneumatic actuator from the valve body. This process also reduces the number of personnel and the maintenance cost of the pneumatic control valve, thereby improving the maintenance effect of the pneumatic control valve.

[0009] In summary, by using the auxiliary tooling in the present application, the number of disassembly and assembly personnel required for disassembly and assembly of the pneumatic control valve is reduced, thereby reducing the disassembly and assembly cost of the pneumatic control valve and improving the disassembly and assembly efficiency of the pneumatic control valve.

[0010] Optionally, each of the clamping rods has a clamping section and connecting sections at both ends of the clamping section, and the clamping sections of the two clamping rods are bent in directions away from each other so that the two clamping sections jointly form a clamping space.

[0011] By adopting the above technical solution, when the pneumatic actuator is clamped and fixed, the pneumatic actuator is located in the clamping space. Since the clamping space is formed by the clamping section bent outward, the connecting sections of the two clamping rods can be abutted together to increase the stability of the clamping rods, thereby improving the fixing stability of the pneumatic actuator.

[0012] Optionally, two driving members are provided, each of which has a driving end capable of moving in a vertical direction, the driving end is provided with a connecting tube, and both ends of each clamping rod are provided with connecting columns respectively extending into the two connecting tubes.

[0013] By adopting the above technical solution, after the two clamping rods clamp and fix the pneumatic actuator, the clamping rods are then installed to the driving end of the driving member so that the connecting column extends into the connecting pipe. In this process, the difficulty of connecting the clamping rods and the driving end is reduced, thereby improving the assembly efficiency of the clamping rods for the disassembly and assembly personnel, and further improving the disassembly and assembly efficiency of the pneumatic actuator.

[0014] Optionally, it also includes a splitting component, which includes a connecting plate and a splitting knife hinged to the connecting plate, two splitting knives are arranged opposite to each other, and the two splitting knives have blades at opposite ends.

[0015] By adopting the above technical solution, when inspecting the pneumatic control valve, if the flange of the pneumatic actuator and the flange of the valve body are rusted together, two splitting knives can be placed on opposite sides of the flanges, and then the splitting knives can be pressed so that the blades of the two splitting knives extend between the two flanges, so that the two flanges are separated by the action of the splitting knives, thereby avoiding the need to knock the pneumatic actuator or the valve body.

[0016] Optionally, the driving member has a connecting portion connected to the disassembly and assembly plate and a telescopic portion capable of relative movement with the connecting portion, the connecting portion is externally sleeved with a collar, and the connecting piece is disposed on the collar.

[0017] By adopting the above technical solution, a ring is provided on the outer sleeve of the connecting part, and a connecting plate is provided on the ring, so that the position of the splitting knife can be adjusted to increase the flexibility of the splitting knife. At the same time, the splitting knife can be rotated to the other side of the connecting part by rotating the ring, so that the splitting knife and the valve body or the pneumatic actuator are avoided, so as to achieve the effect of facilitating the assembly of the pneumatic actuator.

[0018] Optionally, each of the splitting knives has a hinged end hinged to the connecting plate and a free end opposite to the hinged end, and the splitting assembly also includes a driving rod threadedly connected to the two free ends, and when the driving rod rotates, the two free ends move in a direction closer to or away from each other.

[0019] By adopting the above technical solution, during the process of disassembling the pneumatic actuator, if the flange of the pneumatic actuator and the flange of the valve body are rusted together, two splitting knives are placed on both sides of the flange respectively, and then the driving rod is rotated to make the two free ends move towards each other under the action of the driving rod, so that the blade of the splitting knife extends between the two flanges and applies an extrusion force to the two flanges to separate the two flanges. In this process, the disassembly and assembly personnel only need to rotate the driving rod, thereby achieving the effect of facilitating the separation of the pneumatic actuator from the valve body, thereby further improving the disassembly efficiency of the pneumatic actuator.

[0020] Optionally, both free ends are connected to a driving block, and the driving rod is threadedly connected to the two driving blocks.

[0021] By adopting the above technical solution, when the two splitting knives are rotated in a direction approaching each other, the driving rod is rotated, and the driving rod and the driving block rotate relative to each other, so that the two splitting knives are rotated in a direction approaching each other under the action of the two driving blocks. By setting the driving block, the thickness of the splitting knife can be reduced to reduce the weight of the auxiliary tooling, thereby achieving the effect of facilitating the movement and transportation of the auxiliary tooling.

[0022] Optionally, one of the driving blocks is rotatably connected to one of the splitting knives, and another of the driving blocks is detachably connected to another of the splitting knives.

[0023] By adopting the above technical solution, one of the drive blocks is set to be rotatably connected to one of the splitting knives, and the other drive block is detachably connected to the other splitting knife, so that before the two splitting knives are placed on opposite sides of the flange, the drive block is first separated from the splitting knife. When the two splitting knives are respectively located on both sides of the flange, the drive block is connected to the splitting knife together, thereby achieving the effect of facilitating the placement of the two splitting knives on both sides of the flange, thereby improving the disassembly efficiency of the pneumatic actuator.

[0024] Optionally, a receiving groove is provided on a side of one of the splitting knives facing away from the other splitting knife, and the corresponding driving block is located in the receiving groove.

[0025] By adopting the above technical solution, since a receiving groove is provided on the side of one splitting knife facing away from the other splitting knife, and the corresponding driving block is located in the receiving groove, the driving block can be easily installed in the receiving groove, thereby improving the disassembly efficiency of the pneumatic actuator.

[0026] Optionally, each of the splitting knives has a middle section and side sections located at both ends of the middle section, and the two middle sections are bent in directions away from each other.

[0027] By adopting the above technical solution, since the two middle sections are bent in directions away from each other, the distance between the two side sections is reduced to reduce the length of the driving rod, thereby facilitating the miniaturization design of the auxiliary tooling.

[0028] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0029] 1. The auxiliary tooling in the present application includes a disassembly plate and a lifting assembly. The lifting assembly includes two clamping rods for clamping and fixing the pneumatic actuator and a driving member arranged on the disassembly plate. The driving member is used to drive the clamping rods to move in the vertical direction, so that the two clamping rods drive the pneumatic actuator to move in the vertical direction. By using the auxiliary tooling in the present application, the number of disassembly and assembly personnel required for disassembly and assembly of the pneumatic control valve is reduced, thereby reducing the disassembly and assembly cost of the pneumatic control valve and improving the disassembly and assembly efficiency of the pneumatic control valve.

[0030] 2. In the present application, each clamping rod has a clamping section and connecting sections located at both ends of the clamping section. The clamping sections of the two clamping rods are bent in directions away from each other so that the two clamping sections form a clamping space together, and then the connecting sections of the two clamping rods can be in contact with each other to increase the stability of the clamping rod, thereby improving the fixing stability of the pneumatic actuator.

[0031] 3. There are two driving members in the present application, each of which has a driving end capable of moving in the vertical direction, and a connecting tube is provided at the driving end. Both ends of each clamping rod are provided with connecting columns respectively extending into the two connecting tubes, so as to reduce the difficulty of connecting the clamping rod and the driving end, thereby improving the assembly efficiency of the clamping rod for the disassembly and assembly personnel, and further improving the disassembly and assembly efficiency of the pneumatic actuator.

[0047] Reference Figures 1 to 7 , discloses an auxiliary tooling for disassembly and assembly of a regulating valve, including a disassembly plate 1 and a lifting assembly 2, the lifting assembly 2 including two clamping rods 21 for clamping and fixing a pneumatic actuator and a driving member 22 arranged on the disassembly plate 1, the driving member 22 is used to drive the clamping rods 21 to move in the vertical direction, so that the two clamping rods 21 drive the pneumatic actuator to move in the vertical direction.

[0048] When assembling the pneumatic actuator on the valve body, first start the driving member 22 so that the driving member 22 drives the clamping rod 21 upward, and then place the valve body under the clamping rod 21. Then use the two clamping rods 21 to clamp and fix the pneumatic actuator, so that the pneumatic actuator is in a suspended state and is located directly above the valve body. Then start the driving member 22 so that the driving member 22 is under the clamping rod 21, so that the pneumatic actuator falls directly above the valve body. Then fix the pneumatic actuator to complete the assembly of the pneumatic control valve. In this process, the number of people required for disassembly and assembly is reduced, thereby reducing the assembly cost of the pneumatic control valve. At the same time, it avoids the situation where a large number of disassembly and assembly personnel affect the viewing angle, thereby improving the assembly efficiency of the pneumatic control valve.

[0049] When inspecting the pneumatic control valve, first use the clamping rod 21 to clamp and fix the pneumatic actuator, then remove the bolts fixing the pneumatic actuator, and then start the driving member 22, so that the clamping rod 21 drives the pneumatic actuator to move upward. If the flange of the pneumatic actuator and the flange of the valve body are rusted together, the valve body or the pneumatic actuator can be knocked at this time to separate the pneumatic actuator from the valve body. This process also reduces the number of personnel and the maintenance cost of the pneumatic control valve, thereby improving the maintenance effect of the pneumatic control valve.

[0050] In summary, by using the auxiliary tooling in the present application, the number of disassembly and assembly personnel required for disassembly and assembly of the pneumatic control valve is reduced, thereby reducing the disassembly and assembly cost of the pneumatic control valve and improving the disassembly and assembly efficiency of the pneumatic control valve.

[0051] The present application does not specifically limit the structure of the driving member 22. Preferably, refer to Figure 1 , the driving member 22 is a hydraulic cylinder to realize automatic driving of the clamping rod 21. In other embodiments, the driving member 22 can also be a jack, a cylinder or other structures that can be telescopic in the vertical direction.

[0052] In a preferred embodiment, referring to Figure 2 Each clamping rod 21 has a clamping section and connecting sections at both ends of the clamping section. The clamping sections of the two clamping rods 21 are bent in directions away from each other so that the two clamping sections jointly form a clamping space.

[0053] When clamping and fixing the pneumatic actuator, first place the two clamping rods 21 on both sides of the pneumatic actuator respectively so that the pneumatic actuator is located in the clamping space. Since the clamping space is formed by the clamping section bent outward, the connecting sections of the two clamping rods 21 can be abutted together to increase the stability of the clamping rods 21, thereby improving the fixing stability of the pneumatic actuator.

[0054] The present application does not specifically limit the connection method between the clamping rod 21 and the driving member 22. Preferably, refer to Figure 1 , Figure 2 and Figure 3 There are two driving members 22, each of which has a driving end that can move in the vertical direction, and the driving end is provided with a connecting pipe 222. Both ends of each clamping rod 21 are provided with connecting columns 211 that extend into the two connecting pipes 222 respectively.

[0055] It can be understood that the end of the piston rod of the hydraulic cylinder away from the cylinder body constitutes the driving end, that is, a connecting pipe 222 is sleeved on the piston rod of the hydraulic cylinder.

[0056] After the two clamping rods 21 clamp and fix the pneumatic actuator, the clamping rod 21 is then installed to the driving end of the driving member 22 so that the connecting column 211 extends into the connecting tube 222. In this process, the difficulty of connecting the clamping rod 21 and the driving end is reduced, thereby improving the assembly efficiency of the clamping rod 21 for the disassembly and assembly personnel, and further improving the disassembly and assembly efficiency of the pneumatic actuator.

[0057] Better, refer to Figure 2The cross-sectional shape of the connecting tube 222 is circular, and the cross-sectional shape of the connecting column 211 is semicircular. After the connecting column 211 is installed into the connecting tube 222, the arc surface of the connecting column 211 contacts the inner wall of the connecting tube 222 to increase the connection stability between the two.

[0058] In other embodiments, one end of the two clamping rods 21 may be arranged to be hinged to one of the driving ends, and the other end of the clamping rod 21 abuts against the top of the other driving end.

[0059] In a preferred embodiment, referring to Figure 1 , Figure 4 and Figure 6 The auxiliary tooling also includes a splitting component 3, which includes a connecting piece 31 and a splitting knife 32 hinged to the connecting piece 31. Two splitting knives 32 are relatively arranged, and the opposite ends of the two splitting knives 32 have blades.

[0060] When inspecting the pneumatic control valve, if the flange of the pneumatic actuator and the flange of the valve body are rusted together, two splitting knives 32 can be placed on opposite sides of the flanges, and then the splitting knives 32 are pressed so that the blades of the two splitting knives 32 extend between the two flanges, so that the two flanges are separated under the action of the splitting knives 32, thereby avoiding the need to knock the pneumatic actuator or the valve body.

[0061] In a preferred embodiment, referring to Figure 1 The driving member 22 has a connecting portion connected to the disassembly plate 1 and a telescopic portion capable of relative movement with the connecting portion. A sleeve ring 221 is sleeved on the outer portion of the connecting portion, and the connecting piece 31 is arranged on the sleeve ring 221.

[0062] It can be understood that the cylinder body of the hydraulic cylinder constitutes the connecting part, and the piston rod of the hydraulic cylinder constitutes the telescopic part.

[0063] Since the outer sleeve of the connecting part is provided with a collar 221, and the connecting piece 31 is provided on the collar 221, the position of the splitting knife 32 can be adjusted to increase the flexibility of the splitting knife 32. At the same time, the splitting knife 32 can be rotated to the other side of the connecting part by rotating the collar 221, so that the splitting knife 32 and the valve body or the pneumatic actuator are avoided, so as to achieve the effect of facilitating the assembly of the pneumatic actuator.

[0064] In a preferred embodiment, referring to Figure 4 Each splitting knife 32 has a hinged end hinged to the connecting piece 31 and a free end opposite to the hinged end. The splitting assembly 3 also includes a driving rod 33 threadedly connected to the two free ends. When the driving rod 33 rotates, the two free ends move toward or away from each other.

[0065] During the disassembly of the pneumatic actuator, if the flange of the pneumatic actuator and the flange of the valve body are rusted together, the two splitting knives 32 are placed on both sides of the flange respectively, and then the driving rod 33 is rotated to make the two free ends move towards each other under the action of the driving rod 33, so that the blade of the splitting knife 32 extends between the two flanges and applies a squeezing force to the two flanges to separate the two flanges. In this process, the disassembly and assembly personnel only need to rotate the driving rod 33, so as to achieve the effect of facilitating the separation of the pneumatic actuator from the valve body, thereby further improving the disassembly efficiency of the pneumatic actuator.

[0066] Further, see Figure 4 and Figure 7 , both free ends are connected to driving blocks 321 , and the driving rod 33 is threadedly connected to the two driving blocks 321 , that is, the driving rod 33 is provided with threads in opposite directions and is threadedly connected to the two driving blocks 321 , respectively.

[0067] When the two splitting knives 32 are rotated in a direction approaching each other, the driving rod 33 is rotated, and the driving rod 33 and the driving block 321 rotate relative to each other, so that the two splitting knives 32 are rotated in a direction approaching each other under the action of the two driving blocks 321. By setting the driving block 321, the thickness of the splitting knife 32 can be reduced to reduce the weight of the auxiliary tooling, thereby achieving the effect of facilitating the movement and transportation of the auxiliary tooling.

[0068] The present application does not specifically limit the connection method between the driving block 321 and the splitting knife 32, and it can adopt any one of the following embodiments:

[0069] Embodiment 1, in this embodiment, refer to Figure 4 , Figure 5 and Figure 7 , one of the driving blocks 321 is rotatably connected to one of the splitting knives 32, and the other driving block 321 is detachably connected to the other splitting knife 32, so that before placing the two splitting knives 32 on opposite sides of the flange, the driving block 321 is separated from the splitting knife 32, and when the two splitting knives 32 are respectively located on both sides of the flange, the driving block 321 is connected to the splitting knife 32 together, thereby achieving the effect of facilitating the placement of the two splitting knives 32 on both sides of the flange, thereby improving the disassembly efficiency of the pneumatic actuator.

[0070] Further, see Figure 4 and Figure 5 A receiving groove 322 is provided on the side of the splitting knife 32 detachably connected to the driving block 321 facing away from the other splitting knife 32, and the corresponding driving block 321 is located in the receiving groove 322, thereby achieving the effect of facilitating the installation of the driving block 321 into the receiving groove 322, so as to improve the disassembly efficiency of the pneumatic actuator.

[0071] Embodiment 2. In this embodiment, a receiving groove 322 is provided on the side of the two splitting knives 32 facing away from each other, and the two driving blocks 321 are respectively located in the corresponding receiving grooves 322. That is to say, the two driving blocks 321 are detachably connected to the two splitting knives 32 to improve the disassembly efficiency of the pneumatic actuator.

[0072] In a preferred embodiment, referring to Figure 4 and Figure 5 Each splitting knife 32 has a middle section and side sections located at both ends of the middle section, and the two middle sections are bent in directions away from each other.

[0073] Since the two middle sections are bent in directions away from each other, the distance between the two side sections is reduced, so as to reduce the length of the driving rod 33, thereby facilitating the miniaturization design of the auxiliary tooling.

[0074] In a preferred embodiment, a plurality of running wheels are provided at the bottom of the disassembly and assembly plate 1 to facilitate the movement of the auxiliary tooling.

[0075] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0076] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

For those skilled in the art, the present application may have various changes and variations.
