Description

Technical Field

[0001] This utility model is a valve flange disassembly device, belonging to the field of valve flange disassembly equipment. Background Technology

[0002] Valves are important accessories in beer production lines, used to control and regulate the flow of media in pipelines. Due to frequent operation, the sealing and regulating functions of valves often fail, requiring replacement. During valve disassembly, the two flanges of the valve are connected to the flanges of the pipeline through steel rings and gaskets. Over time, the steel rings and gaskets become tightly connected to the flanges, making it impossible to remove the valve. Therefore, a disassembly tool is needed to remove the bolts from the pipeline valve and flange.

[0003] In the existing technology, most devices can be disassembled and processed in a conventional manner and can be used for pipe valves of different sizes. However, most devices often cannot stably clamp and fix pipe valves of different sizes during use, which reduces the stability of the device and also reduces its practicality and versatility. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a valve flange disassembly device.

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

[0006] A valve flange disassembly device includes a housing, a working space on one side of the front of the housing, a storage groove on each side of the inner wall of the working space, a clamping assembly inside the storage groove, and an inner cavity inside the housing, wherein a driving assembly that cooperates with the clamping assembly is provided inside the inner cavity.

[0007] Furthermore, the clamping assembly includes a fixed plate slidably connected within the storage groove, a mating plate fixed to one side of the outer surface of the fixed plate, the mating plate slidably connected within a mating groove, and the mating groove being formed on the bolt clamping plate.

[0008] Furthermore, the outer surface of the docking plate is provided with a plurality of magnetic adsorption plates, and the inner wall of the docking groove is provided with metal sheets that cooperate with the magnetic adsorption plates.

[0009] Furthermore, the drive assembly includes a sliding plate slidably connected within the inner cavity, a protruding rod fixed to the middle of one side of the sliding plate, the protruding rod extending through to the outer side of the housing, and two connecting rods symmetrically arranged on the other side of the sliding plate, with inclined seats fixed to the ends of the connecting rods.

[0010] Furthermore, the drive assembly also includes two sets of sliders symmetrically slidably connected within the inner cavity. A ramp block that cooperates with the ramp seat is fixed in the middle of one side of the slider, and a crossbar is fixed in the middle of the other side of the slider. The crossbar movably passes through the inside of the storage groove and is connected and fixed to the fixing plate. A spring is sleeved on the outer surface of the crossbar between the slider and the inner wall of the inner cavity.

[0011] Furthermore, several limiting grooves are evenly spaced on both sides of the inner wall of the housing, and limiting plugs are inserted into the limiting grooves. The ends of the limiting plugs penetrate into the inner cavity and abut against the sliding plate.

[0012] Furthermore, the inner wall of the limiting groove is provided with several damping strips, and the outer surface of the limiting plug is provided with damping strips. The damping strips are pressed together with the damping strips.

[0013] Furthermore, both the inclined plate and the sliding plate have guide blocks on their outer surfaces, and guide grooves are formed on the inner wall of the inner cavity.

[0014] The beneficial effects of this utility model are:

[0015] Due to the design of the clamping assembly, during use, the bolt clamping plate with the corresponding clamping groove needs to be installed on the fixing plate according to the type of bolt. Then, the working space on the housing is matched with the bolt of the valve or flange.

[0016] The design of the drive assembly pushes the protruding rod into the housing to move the sliding plate. When the sliding plate moves, it pushes the inclined seat to move through the connecting rods on both sides. The inclined seat pushes the inclined block to move through the inclined surface compression. The movement of the inclined block pushes the fixed plate and bolt clamping plate to move through the crossbar. The bolts are clamped and fixed by the relative movement of the bolt clamping plates on both sides.

[0017] The design of the limiting groove and the limiting plug plate can be used to abut and limit the sliding plate after the position is adjusted, so as to prevent the sliding plate from resetting and moving back.

[0018] By designing damping strip one and damping strip two, the friction between the limiting groove and the limiting plug is increased, thereby improving the stability of the limiting plug. Attached Figure Description

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.

[0027] Please see Figures 1-5 This utility model provides a technical solution for a valve flange disassembly device, including a housing 1. A working space 11 is provided on one side of the front of the housing 1. A storage groove 12 is provided on both sides of the inner wall of the working space 11. A clamping component is provided inside the storage groove 12. An inner cavity 2 is provided inside the housing 1. A driving component that cooperates with the clamping component is provided inside the inner cavity 2.

[0028] See Figures 4-5The clamping assembly includes a fixed plate 13 slidably connected within the storage groove 12. A mating plate 15 is fixed to one side of the outer surface of the fixed plate 13. The mating plate 15 is slidably connected within a mating groove 16, which is formed on a bolt clamping plate 14. Through the design of the clamping assembly, during use, the bolt clamping plate 14 with the corresponding clamping groove needs to be installed on the fixed plate 13 according to the type of bolt. Subsequently, the working space 11 on the housing 1 is matched with the bolts of the valve or flange. The outer surface of the mating plate 15 is provided with several magnetic adsorption plates, and the inner wall of the mating groove 16 is provided with metal sheets that cooperate with the magnetic adsorption plates. The design of the magnetic adsorption plates and metal sheets improves the stability of the connection between the mating plate 15 and the fixed plate 13.

[0029] See Figures 2-4 The driving assembly includes a sliding plate 3 slidably connected within the inner cavity 2. A protruding rod 4 is fixed to the middle of one side of the sliding plate 3, extending through to the outside of the housing 1. Two connecting rods 5 are symmetrically arranged on the other side of the sliding plate 3, and inclined seats 6 are fixed to the ends of the connecting rods 5. The driving assembly also includes two sets of sliders 7 symmetrically slidably connected within the inner cavity 2. An inclined block 8 that cooperates with the inclined seat 6 is fixed to the middle of one side of each slider 7. A crossbar 9 is fixed to the middle of the other side of each slider 7, and the crossbar 9 movably extends through the storage groove 12 and is connected and fixed to the fixing plate 13. A spring 10 is fitted on the outer surface of the crossbar 9 and between the slider 7 and the inner wall of the inner cavity 2. Guide blocks are provided on the outer surfaces of both the inclined seat 6 and the sliding plate 3. A guide groove is provided on the inner wall of the inner cavity 2. Through the design of the drive assembly, the protruding rod 4 is pushed into the housing 1 to drive the sliding plate 3 to move. When the sliding plate 3 moves, it pushes the inclined seat 6 to move through the connecting rods 5 on both sides. The inclined seat 6 pushes the inclined block 8 to move through the inclined surface compression. The movement of the inclined block 8 pushes the fixing plate 13 and the bolt clamping plate 14 to move through the crossbar 9. The bolts are clamped and fixed by the relative movement of the bolt clamping plates 14 on both sides.

[0030] See Figure 1 , Figure 2The inner walls of both sides of the housing 1 are provided with a plurality of limiting grooves 17 at equal intervals. Limiting plugs 18 are inserted into the limiting grooves 17. The ends of the limiting plugs 18 extend into the inner cavity 2 and abut against the sliding plate 3. Through the design of the limiting grooves 17 and the limiting plugs 18, the sliding plate 3 can be abutted and limited after the position is adjusted, so as to prevent the sliding plate 3 from resetting and moving back. The inner wall of the limiting grooves 17 is provided with a plurality of damping strips 1, and the outer surface of the limiting plugs 18 is provided with damping strips 2. The damping strips 2 and 1 are pressed together. Through the design of the damping strips 1 and 2, the friction between the limiting grooves 17 and the limiting plugs 18 is increased, thereby improving the stability of the limiting plugs 18.

[0031] In use, first install the bolt clamping plate 14 with the corresponding clamping groove on the fixing plate 13 according to the type of bolt. Then, match the working space 11 on the housing 1 with the bolt of the valve or flange. Next, push the protruding rod 4 into the housing 1 to drive the sliding plate 3 to move. When the sliding plate 3 moves, it pushes the inclined seat 6 to move through the connecting rods 5 on both sides. The inclined seat 6 pushes the inclined block 8 to move through the inclined surface compression. The movement of the inclined block 8 pushes the fixing plate 13 and the bolt clamping plate 14 to move through the crossbar 9. The bolt is clamped and fixed by the relative movement of the bolt clamping plates 14 on both sides. After the sliding plate 3 is adjusted, insert the limiting plug 18 into the corresponding limiting groove 17 to limit the sliding plate 3. At this time, the bolt clamping plates 14 on both sides are locked with the bolt. Then, the user holds the housing 1 and rotates it to disassemble the bolt on the valve or flange. It should be noted that when holding the housing 1, the limiting plugs 18 on both sides need to be pressed to prevent the limiting plugs 18 from disengaging from the housing 1 during rotation.
