Description

Technical Field

[0001] This utility model relates to the field of safety valves, and in particular to a disassembly tool for safety valves. Background Technology

[0002] A safety valve is a special valve that is normally closed under external force. When the pressure of the medium in the equipment or pipeline rises above a specified value, it discharges the medium to the outside of the system to prevent the pressure of the medium in the pipeline or equipment from exceeding the specified value. Safety valves belong to the category of automatic valves and are mainly used on boilers, pressure vessels, and pipelines to control the pressure to not exceed the specified value. They play an important role in protecting personal safety and equipment operation. Note that safety valves must undergo a pressure test before use. When replacing or installing a safety valve, disassembly tools are required to disassemble or tighten it.

[0003] When workers repair or install safety valves, they need to carry disassembly tools with them. However, the handles of existing safety valve disassembly tools are mostly too long. While this makes it easier for workers to apply force to operate the handles, the excessively long handles make it inconvenient for workers to carry them with them, causing inconvenience for the repair or installation of safety valves. Therefore, we propose a safety valve disassembly tool to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a disassembly tool for safety valves to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A safety valve disassembly tool includes a main rod, a disassembly mechanism fixedly connected to the outer surface of the main rod, an operating mechanism movably hinged to the outer surface of the main rod via a hinge, and a sliding groove formed on the outer surface of the main rod, with a slider slidably connected inside the sliding groove.

[0007] In a further embodiment, the disassembly mechanism includes a fixing frame, the outer surface of which has two first threaded holes.

[0008] In a further embodiment, the two first threaded holes are connected by a common threaded rod, and a limit block is fixedly connected to the right end of the first threaded rod. The outer surface of the limit block is fixedly connected to the outer surface of the slider.

[0009] In a further embodiment, a clamping plate is fixedly connected to the left end of the first threaded rod, an adjusting block is threadedly connected to the outer surface of the first threaded rod, and a plurality of toothed blocks are fixedly connected to the outer surface of the clamping plate and the outer surface of the main rod.

[0010] In a further embodiment, the operating mechanism includes a slave rod, and the outer surface of the slave rod and the outer surface of the main rod are both fixedly connected to a fixing plate.

[0011] In a further embodiment, the outer surfaces of both fixing plates are provided with second threaded holes, and the interiors of the two second threaded holes are connected to a second threaded rod by a common thread. An auxiliary rod is fixedly connected to the outer surface of the rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device utilizes a second threaded hole to allow workers to fix or disassemble the two fixing plates via the second threaded rod, thereby fixing or releasing the drag rod. The drag rod can then be folded down, reducing the overall length of the device and making it easier for workers to carry. This solves the problem of inconvenience caused by excessively long disassembly tools. A slider restricts the vertical movement of the limiting block, improving the balance between the first threaded rod and the clamping plate. The first threaded rod allows adjustment of the distance between the clamping plate and the main rod, enabling the clamping of safety valves of different sizes. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4In this utility model, a disassembly tool for a safety valve includes a main rod 1. A disassembly mechanism 2 is fixedly connected to the outer surface of the main rod 1. The disassembly mechanism 2 includes a fixing frame 201. Two first threaded holes 202 are formed on the outer surface of the fixing frame 201. A first threaded rod 203 is threadedly connected to the interior of the two first threaded holes 202. A limit block 204 is fixedly connected to the right end of the first threaded rod 203. The outer surface of the limit block 204 is fixedly connected to the outer surface of the slider 5. A clamping plate 205 is fixedly connected to the left end of the first threaded rod 203. An adjusting block 206 is threadedly connected to the outer surface of the first threaded rod 203. Several toothed blocks 207 are fixedly connected to the outer surface of the holding plate 205 and the outer surface of the main rod 1. The first threaded hole 202 is used to assist the translation of the first threaded rod 203. The adjusting block 206 is used to help the operator translate the first threaded rod 203. The limiting block 204 is used to limit the translation of the first threaded hole 202 to prevent it from separating from the fixing frame 201. The toothed blocks 207 are used to increase the friction between the holding plate 205 and the main rod 1 and the outside of the safety valve to prevent the operator from sliding when disassembling or installing and tightening the safety valve.

[0023] An operating mechanism 3 is hinged to the outer surface of the main rod 1. The operating mechanism 3 includes a secondary rod 301. A fixing plate 302 is fixedly connected to both the outer surface of the secondary rod 301 and the outer surface of the main rod 1. A second threaded hole 303 is provided on the outer surface of both fixing plates 302. A second threaded rod 304 is threadedly connected to the interior of the two second threaded holes 303. An auxiliary rod 305 is fixedly connected to the outer surface of the secondary rod 301. The second threaded hole 303 facilitates the installation of the second threaded rod 304. The second threaded rod 304 helps the operator to fix the main rod 1 and the secondary rod 301 to each other. After the secondary rod 301 is released from its fixation, it can be folded by the hinge, thereby shortening the overall length of the device. A sliding groove 4 is provided on the outer surface of the main rod 1. A slider 5 is slidably connected inside the sliding groove 4. The slider 5 helps the operator to limit the position of the limiting block 204, preventing it from moving up and down and affecting the balance of the clamping plate 205.

[0024] The working principle of this utility model is as follows:

[0025] In use, firstly, the second threaded rod 304 is used to fix the main rod 1 and the driven rod 301 to each other through the second threaded hole 303. Then, the adjusting block 206 is rotated counterclockwise or clockwise. When the adjusting block 206 rotates, it will drive the first threaded rod 203 to move horizontally. When the first threaded rod 203 moves horizontally, the slider 5 will slide horizontally in the groove 4 to restrict the limit block 204 and prevent it from moving up and down. Then, according to the size of the safety valve, the distance between the clamping plate 205 and the main rod 1 is adjusted by the horizontal movement of the first threaded rod 203. Finally, the clamping plate 205 and the main rod 1 are positioned outside the safety valve. Then, the adjusting block 206 is rotated again to make the first threaded rod 203 move horizontally in the opposite direction. Then, the safety valve is clamped by the clamping plate 205. Then, force is applied to the auxiliary rod 305 or the driven rod 301 to drive the entire device to rotate, and then the safety valve can be disassembled or installed.
