Description

Technical Field

[0001] This utility model relates to the field of valve technology, and in particular to a quick-disassembly and assembly regulating valve. Background Technology

[0002] Control valves are indispensable key control components in fluid pipeline systems and are widely used in many industrial fields such as chemical, petroleum, power and food processing to regulate the flow, pressure and temperature parameters of the medium. In many industrial production processes, pipeline systems require regular maintenance and repair, which involves the frequent installation and disassembly of control valves.

[0003] Currently, the mainstream connection method between control valves and pipelines is flange connection. This involves setting multiple bolt holes on the flange of the control valve and pipeline, and using multiple bolts and nuts to fasten them together. However, this traditional connection method has obvious shortcomings. First, during installation or disassembly, operators must use tools to tighten or loosen a large number of bolts one by one in stages. The whole process is cumbersome, time-consuming, and labor-intensive, especially in situations where space is limited or emergency repairs are needed, where its inefficiency is even more pronounced. Second, to ensure a sealing effect, the tightening torque of the flange bolts must be uniform and consistent, which is difficult to control precisely in actual operation. If the tightening force is uneven, it is easy to cause improper stress on the sealing gasket, resulting in potential leakage. Frequent disassembly and assembly will also accelerate the wear of threads and seals, further reducing the long-term reliability of the connection.

[0004] Therefore, this utility model proposes a quick-disassembly and assembly regulating valve to overcome the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems of cumbersome and time-consuming disassembly and assembly, low efficiency, and insufficient connection and sealing reliability of existing control valves, this utility model aims to provide a control valve with an improved structure that can effectively solve the above problems and allow for quick disassembly and assembly.

[0006] This utility model provides a quick-disassembly and assembly regulating valve, including a regulating valve, a pipeline, and a disassembly and assembly mechanism and a sealing mechanism disposed between the regulating valve and the pipeline.

[0007] The disassembly and assembly mechanism includes a first fixing plate, a second fixing plate, a positive fixing bolt, a negative fixing bolt, a long gear, a large gear, and a rotating rod; the sealing mechanism includes a first sealing ring and a sealing plate.

[0008] Furthermore, the fixing plates one and two in the disassembly and assembly mechanism are used to clamp the regulating valve and the pipeline. The positive fixing bolt and the negative fixing bolt are rotatably connected to the fixing plates one and two respectively and threadedly engaged. The two long gears are fixed on the positive fixing bolt and the negative fixing bolt respectively. The large gear meshes with the two long gears at the same time. The rotating rod is coaxially fixedly connected to the large gear. The sealing ring one in the sealing mechanism is used to thread the regulating valve and the pipeline. The sealing plate is fixed on the adjacent side of the regulating valve and the pipeline.

[0009] Preferably, the quick-release regulating valve also includes a housing, a limiting plate, a limiting hole, and a limiting post. The housing is covered outside the long gear and the large gear, the limiting plate is fixed to the outer wall of the rotating rod, and both the housing and the limiting plate are provided with limiting holes. The limiting post engages with the limiting hole to achieve locking.

[0010] Preferably, the positive fixing bolt is threaded into the positive threaded hole provided on the first fixing plate, and the negative fixing bolt is threaded into the negative threaded hole provided on the second fixing plate.

[0011] Preferably, the axis of the rotating rod is perpendicular to the axes of the positive fixing bolt and the negative fixing bolt.

[0012] Preferably, the outer wall of the sealing plate and the inner wall of the sealing ring form a limiting fit.

[0013] Preferably, the sealing mechanism further includes a second sealing ring, and an inner ring is fixedly connected to the middle of the inner wall of the first sealing ring.

[0014] Preferably, the outer wall of the sealing ring two has a groove that engages with the inner ring.

[0015] Preferably, the quick-release regulating valve also includes a sealing ring disposed on one side of the two sealing plates, the sealing ring abutting against the second sealing ring.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model integrates the operation of multiple fastening points into a single-point synchronous operation by setting up a linkage mechanism consisting of a rotating rod, a large gear, a long gear, and positive and negative fixing bolts. This solves the problem that the disassembly and assembly of regulating valves in the prior art requires the operation of multiple bolts one by one, which is cumbersome and inefficient. It achieves the technical effect of fastening or disassembly quickly and effortlessly, significantly improving work efficiency and shortening equipment maintenance time.

[0018] 2. This utility model, by employing a double-layer sealing mechanism that uses the inner ring between the sealing rings and the groove for mechanical engagement, and in conjunction with the sealing rubber ring for elastic sealing, solves the problems of simple sealing structure, poor reliability, and easy leakage due to frequent disassembly and assembly in the valve connection in the prior art. It achieves the technical effect of excellent sealing performance and high reliability, effectively ensuring the safe operation of the pipeline system.

[0019] 3. This utility model, by setting a locking device consisting of a limiting plate, a limiting hole and a limiting post, can lock the entire disassembly and assembly mechanism after the regulating valve is tightened, which solves the problem of loose connection caused by equipment vibration or accidental contact in the clamping state, and achieves the technical effect of improving connection stability and long-term reliability.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 5This utility model provides a quick-disassembly and assembly regulating valve, which aims to solve the problems of cumbersome disassembly and assembly operations, low efficiency and insufficient connection sealing of the regulating valve in the prior art.

[0030] like Figure 1 and Figure 2 As shown, the quick-release regulating valve includes a regulating valve 1 and a pipeline 4, as well as an assembly for connecting the regulating valve 1 and the pipeline 4. The assembly mainly consists of a disassembly mechanism 2 and a sealing mechanism 3. The disassembly mechanism 2 is used to quickly clamp or release the regulating valve 1 and the pipeline 4, while the sealing mechanism 3 is used to seal the connection between the regulating valve 1 and the pipeline 4.

[0031] To achieve rapid disassembly and assembly, the structure of this embodiment consists of disassembly and assembly mechanism 2, and sealing mechanism 3 forms a specific sealing fit relationship with regulating valve 1 and pipeline 4.

[0032] Please refer to the following carefully. Figure 3 The structure of disassembly and assembly mechanism 2 will be described in detail below:

[0033] The disassembly and assembly mechanism 2 includes a first fixing plate 201 and a second fixing plate 213, which are arranged vertically opposite each other to clamp the regulating valve 1 and the pipeline 4. The disassembly and assembly mechanism 2 also includes a positive fixing bolt 204 and a negative fixing bolt 207 rotatably connected to the first fixing plate 201 and the second fixing plate 213. The positive fixing bolt 204 is threaded into a positive threaded hole 205 provided on the first fixing plate 201, and the negative fixing bolt 207 is threaded into a negative threaded hole 208 provided on the second fixing plate 213. The top ends of the 04 and the anti-fixing bolt 207 are respectively fixedly connected with long gears 206. The disassembly and assembly mechanism 2 further includes a large gear 212 that meshes with the two long gears 206 at the same time, and a rotating rod 203 that is fixedly connected to the large gear 212 on the same axis. The axis of the rotating rod 203 is perpendicular to the axis of the positive fixing bolt 204 and the anti-fixing bolt 207. This linkage structure, which drives the positive and negative bolts synchronously through a gear system via a single rotating rod 203, ensures that the regulating valve 1 and the pipeline 4 can be clamped and released quickly, smoothly and synchronously.

[0034] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0035] As a preferred embodiment, to prevent accidental rotation of the rotating rod 203 after fixing, please refer to... Figure 2 and Figure 3The disassembly and assembly mechanism 2 also includes a housing 202 covering the long gear 206 and the large gear 212. A limiting plate 209 is fixed on the outer wall of the rotating rod 203. Limiting holes 210 are provided at the top of the housing 202 and the top of the limiting plate 209 respectively. When the rotating rod 203 rotates to the clamping position, the limiting pin 211 can be inserted into the two limiting holes 210 to lock the rotating rod 203.

[0036] As another preferred embodiment, for achieving a reliable seal, please refer to... Figure 4 and Figure 5 The sealing mechanism 3 includes a sealing ring 301 for threaded connection between the regulating valve 1 and the pipe 4. Two sealing plates 306 are also fixedly connected on the adjacent side of the regulating valve 1 and the pipe 4. The outer walls of the two sealing plates 306 and the inner wall of the sealing ring 301 form a limiting fit. The sealing mechanism 3 also includes a sealing ring 302. An inner ring 304 is fixedly connected to the middle of the inner wall of the sealing ring 301. The outer wall of the sealing ring 302 is provided with a groove 305 that engages with the inner ring 304. In addition, a sealing rubber ring 303 is fixedly connected on the adjacent side of the two sealing plates 306. The sealing rubber ring 303 abuts against the sealing ring 302.

[0037] Working principle: The regulating valve 1 and the pipeline 4 are clamped by the fixing plate 201 and fixing plate 213 in the disassembly and assembly mechanism 2. The regulating valve 1 and the pipeline 4 are fixed by rotating the positive fixing bolt 204 and the negative fixing bolt 207 to the positive threaded hole 205 and the negative threaded hole 208. Long gears 206 are fixedly connected to the top of the positive fixing bolt 204 and the negative fixing bolt 207. The serrations of the two long gears 206 engage with the serrations of the large gear 212. A rotating rod 203 is fixedly connected to the top of the large gear 212. Rotating the rotating rod 203 drives the two long gears 206. 6. Rotation causes the positive fixing bolt 204 and the negative fixing bolt 207 to move up and down, so that the regulating valve 1 and the pipeline 4 can be disassembled simply by rotating the rotating rod 203. The outer shell 202 is fixedly connected to the top of the fixed plate 201 to protect the long gear 206 and the large gear 212. The outer wall of the rotating rod 203 is fixed with a limit plate 209. Limiting holes 210 are provided at the top of the outer shell 202 and the top of the limit plate 209. When the rotating rod 203 rotates to the appropriate position, the limiting post 211 engages with the limiting hole 210 to prevent the rotating rod 203 from rotating. This device improves the disassembly efficiency of the equipment.

[0038] Furthermore, the regulating valve 1 is threadedly connected to the pipeline 4 via the sealing ring 301 in the sealing mechanism 3. Two sealing plates 306 are fixedly connected to the adjacent side of the regulating valve 1 and the pipeline 4. The outer walls of the two sealing plates 306 engage with the inner walls of the sealing ring 301 on the left and right sides. An inner ring 304 is fixedly connected to the middle of the inner wall of the sealing ring 301. A groove 305 is provided on the outer wall of the sealing ring 302. The inner ring 304 engages with the groove 305, increasing the sealing effect. A sealing rubber ring 303 is also fixedly connected to the adjacent side of the two sealing plates 306. The sealing rubber ring 303 and the sealing ring 302 form a double-layer sealing effect, improving the equipment's sealing performance.
