Description

Technical Field

[0001] This utility model relates to the field of industrial safety equipment technology, specifically to an explosion-proof valve with an adjustable installation angle. Background Technology

[0002] Existing explosion-proof valves are installed in both horizontal and vertical directions. With industrial development, especially in later renovation projects, explosion-proof valves may need to be installed at an angle or at a height. This makes it difficult to adapt to complex working conditions and requires manual calculation of how many valves are needed at what angle. With a large workload, this is a waste of manpower.

[0003] For existing explosion-proof valves, the installation angle is fixed at the factory; horizontal valves can only be installed horizontally, and vertical valves can only be installed vertically. In retrofit projects or on-site construction, it is highly likely that the working conditions were not taken into account, and the explosion-proof valve originally planned for horizontal installation will need to be installed horizontally on site. In this case, the only option is to replace the valve or send replacement parts for adjustment, which will inevitably waste time and extend the construction period. Moreover, most existing explosion-proof valves do not have valve disc reset components, which means that manual reset is required during use, wasting manpower and time. At the same time, the drive rod and drive disc that drive the valve disc to flip are mostly connected by bolts. Although bolt connections are effective, they are inefficient during the connection process.

[0004] Therefore, how to provide an explosion-proof valve with an adjustable installation angle to solve the defects of the existing explosion-proof valve structure is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] Therefore, this utility model provides an explosion-proof valve with an adjustable installation angle to solve the problems of construction period and labor cost caused by the fact that the explosion-proof valve cannot adapt to different installation angles at the same time and the valve disc is not equipped with an automatic reset component in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model discloses an explosion-proof valve with an adjustable installation angle, comprising:

[0008] The mounting housing has a hollow internal structure, and two connecting pipes are installed on the side wall of the mounting housing, which are connected to the dust transport pipe.

[0009] A flip-up assembly is installed in the mounting housing, with both ends of the flip-up assembly extending out of the mounting housing;

[0010] The first reset component is mounted on the side wall of the mounting housing;

[0011] The drive component is inserted at one end of the flipping component;

[0012] The valve disc is connected at one end to the flipping assembly, and the valve disc is flipped and connected in the hollow structure;

[0013] The second reset component is installed at the other end of the flip component.

[0014] In one possible implementation, the flipping component includes:

[0015] Connecting pieces are arranged in pairs and installed on two surfaces of the mounting housing. A drive rod is connected to the connecting pieces and the mounting housing. The second reset component is installed on one end surface of the drive rod.

[0016] A plurality of gaskets are fitted onto the drive rod, and a connecting ring is installed between the gaskets. The connecting ring is fitted onto the drive rod, and the drive assembly is inserted into the connecting ring.

[0017] A push block is mounted on the drive rod, and the push block is disposed inside the gasket.

[0018] A rectangular hole is formed at one end of the drive rod, and two symmetrical limiting grooves are provided on the side of the rectangular hole.

[0019] In one possible implementation, the second reset component includes:

[0020] A displacement rod is driven to one end in the rectangular hole, and a limit block is installed on the side of the displacement rod. The limit block is driven to the limit groove.

[0021] A limiting disc is installed at the other end of the displacement rod, and a driving spring is installed between the limiting disc and the connecting disc.

[0022] In one possible implementation, the connecting ring includes:

[0023] The ring body has six holes in the middle and several insertion holes on the outer surface of the ring body;

[0024] Guide grooves are provided in pairs and are formed on the side wall of the socket. One end of the guide groove extends to the side surface of the ring body, and the other end of the guide groove is connected to a hemispherical hole, which is provided on the inner wall of the socket.

[0025] In one possible implementation, the driving component includes:

[0026] A round rod has an external thread structure on its surface. Nuts are fitted on the outside of the external thread structure. The nuts are arranged in pairs. Several counterweights are installed between the two nuts. The counterweights are fitted on the outside of the round rod.

[0027] A connecting hole is formed at the end of the round rod, and a displacement hole is formed on the side wall of the connecting hole;

[0028] A translation rod is connected in the displacement hole, and a hemisphere and a baffle are respectively connected to both ends of the translation rod.

[0029] A return spring is installed between the two baffles.

[0030] In one possible implementation, the first reset component includes:

[0031] A connector is mounted on the outer surface of the mounting housing, and a cylindrical and gear component is mounted on the surface of the connector.

[0032] A movable rod is connected in the cylinder for transmission, and a rack is connected to the end of the movable rod, which meshes with the gear component.

[0036] A torsion spring is sleeved on the outside of the push rod, and the torsion spring is installed between the gear and the surface of the connecting member.

[0037] This invention utilizes a drive assembly to rotate the valve disc. The weight of the drive assembly itself keeps the valve disc in either an open or closed position. Whether installed horizontally or vertically, simply inserting the drive assembly into different positions on the rotating assembly will rotate the valve disc. This allows the explosion-proof valve to adapt to various installation positions and angles, avoiding the cost and time waste caused by remanufacturing the explosion-proof valve. When the drive assembly is removed, the first and second reset components work simultaneously to reset the valve disc, thus enabling normal operation. This effectively reduces the need for manual reset operations, lowering labor costs and time. Furthermore, the plug-in limiting method used for the drive assembly and rotating assembly improves the efficiency of drive assembly installation and removal, thereby increasing overall project efficiency.

Detailed Implementation

[0053] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0054] Please refer to Figures 1-12 The present invention discloses an explosion-proof valve with an adjustable installation angle. The present invention consists of seven parts, as follows: Figures 1-2 The assembly includes a valve disc 1, a first reset component 2, a flipping component 3, a drive component 4, a mounting housing 5, a connecting pipe 6, and a second reset component 7. The mounting housing 5 has a hollow internal structure. Two connecting pipes 6 are installed on the side wall of the mounting housing 5 and are connected to a dust transport pipe. The flipping component 3 is installed in the mounting housing 5, with both ends of the flipping component 3 protruding from the mounting housing 5. The first reset component 2 is installed on the side wall of the mounting housing 5. The end of the drive component 4 is inserted into one end of the flipping component 3. The end of the valve disc 1 is connected to the flipping component 3 and flipped into the hollow structure. The second reset component 7 is installed at the other end of the flipping component 3.

[0055] In use, this invention connects the explosion-proof valve (without the drive assembly) to two pipe sections. During connection, the flange on the connecting pipe 6 is connected to the flange on the dust transport pipe. This allows the explosion-proof valve to be integrated into the entire pipeline. After connection, under the action of the two limiting components, one end of the valve disc 1 is pressed against the inner wall of the mounting housing 5, and the valve is in a closed state. This isolates dust and fibers, thus creating an explosion-proof effect and protecting upstream equipment. After disconnecting from the upstream equipment, the substances and pressure in the pipeline need to be released to avoid the risk of explosion. Release requires opening the explosion-proof valve. When opening the explosion-proof valve, insert the end of the round rod 42 with the hemisphere 45 into the insertion hole 361. Before insertion, press the two hemispheres 45 to retract them into the displacement hole 48. Then insert the round rod 42 into the insertion hole 361, aligning the hemispheres 45 with the guide groove 362 before insertion. When the hand is released, the return spring 47 drives the hemisphere 45 to move outward from the displacement hole 48. The outer surface of the hemisphere 45 eventually abuts against the side wall of the guide groove 362. During the continued insertion of the round rod 42, the return spring 47 remains compressed. When the hemisphere 45 enters the hemisphere hole 363, the return spring 47 drives the hemisphere 45 to move outward again, and the outer surface of the hemisphere 45 eventually abuts against the surface of the hemisphere hole 363. The opening depth of the hemisphere hole 363 is deeper than that of the guide groove 362, allowing the guide groove 362 to hold the hemisphere 45. Simultaneously, the return spring 47 compresses the two hemispheres 45, creating friction between them and the hemisphere hole 363, thus limiting the insertion of the round rod 42. The insertion hole 361 for the round rod 42 is determined by the installation angle of the explosion-proof valve. The insertion position differs between horizontal and vertical installations. Figures 11-12As shown, by setting several insertion holes 361 and cooperating with the drive assembly 4, the explosion-proof valve can be adapted to various installation angles. The valve opening operation is achieved by installing a counterweight 41 on the round rod 42. The gravity generated by the counterweight 41 drives one end of the inserted round rod 42 to deflect downwards, which causes the connecting ring 36 to rotate, thereby causing the drive rod 33 to rotate. During the rotation of the flipping assembly 3, in addition to causing the valve disc 1 to flip and generate the valve opening operation, the first reset assembly 2 and the second reset assembly 7 can also generate movement and reset force. After the valve opening operation is completed, the drive assembly 4 can be removed or the counterweight can be removed. When block 41 is removed, the resetting force of the first reset component 2 and the second reset component 7 causes the connecting ring 36 to rotate in the opposite direction, and causes the drive rod 33 to rotate in the opposite direction. This causes the drive rod 33 to drive the valve disc 1 to flip back to its original position, so that the valve disc 1 continues to have a sealing effect. When there is a strong pressure in the pipeline, the pressure will also cause the valve disc 1 to flip. At this time, the drive component 4 can be installed in the opposite position to the position that drives the valve disc 1 to open. This makes the valve disc 1 have a tendency to rotate in the opposite direction to overcome the pressure in the pipeline and keep the explosion-proof valve in the closed state. A stop rod 2 is set inside the housing 5 to limit the rotation angle of the valve disc 1.

[0056] In a specific embodiment, such as Figures 3-4The flipping assembly 3 includes a connecting piece 31, a push block 32, a drive rod 33, a gasket 35, a connecting ring 36, a rectangular hole 37, and a limiting groove 38. The connecting pieces 31 are arranged in pairs and installed on the two surfaces of the mounting housing 5. The drive rod 33 is connected to the connecting piece 31 and the mounting housing 5. A second reset assembly 7 is installed on one end surface of the drive rod 33. Several gaskets 35 are sleeved on the drive rod 33. A connecting ring 36 is installed between the gaskets 35. The connecting ring 36 is sleeved on the drive rod 33. A drive assembly 4 is inserted into the connecting ring 36. The push block 32 is installed on the drive rod 33 and is located inside the gasket 35. The rectangular hole 37 is opened at one end of the drive rod 33. Two symmetrical limiting grooves 38 are provided on the side of the rectangular hole 37. The connecting piece 31 is used to connect the flip assembly 3 and the mounting housing 5 together. The connecting piece 31 is fixed to the side wall of the mounting housing 5 by bolts. In this way, the position of the two connecting pieces 31 remains unchanged, which keeps the position of the drive rod 33 unchanged. This avoids the situation where the drive rod 33 is offset due to the heavier end of the flip assembly 3 carrying the drive assembly 4, which would cause the valve to be loose. When the push block 32 rotates with the drive rod 33, it will slowly drive the first reset assembly 2 to move. The gasket 35 is installed on the drive rod 33, and the connecting ring 36 is installed between the gaskets 35. The connecting ring 36 is fixed by the setting of the gasket 35 to prevent the connecting ring 36 from being offset during rotation. The rectangular hole 37 allows the displacement rod 72 to translate, while the limiting groove 38 can guide the second reset assembly 7 to move and prevent the displacement rod 72 from rotating in the rectangular hole 37, thereby affecting the effect of the drive spring 71.

[0057] In a specific embodiment, such as Figure 5The second reset assembly 7 includes a drive spring 71, a displacement rod 72, a limiting disc 73, and a limiting block 74. One end of the displacement rod 72 is drivenly connected to the rectangular hole 37, and the limiting block 74 is installed on the side of the displacement rod 72. The limiting block 74 is drivenly connected to the limiting groove 38. The limiting disc 73 is installed at the other end of the displacement rod 72, and the drive spring 71 is installed between the limiting disc 73 and the connecting piece 31. During rotation, the drive rod 33 synchronously drives the displacement rod 72 and the limiting block 74 to rotate. Since one end of the drive spring 71 is connected to the connecting piece 31, the drive spring 71 deforms and generates elastic force due to the stationary position of one end and the twisting of the other end. This causes the drive spring 71 to compress and deform. During the compression of the drive spring 71, one end of the drive spring 71 pulls the displacement rod 72 to move along the rectangular hole 37. This allows the limiting disc 73 to move closer to the connecting piece 31, assisting in the compression of the spring. This also effectively prevents the drive spring 71 from breaking. When the valve disc 1 needs to be reset, the elastic force generated by the compression of the drive spring 71 drives the displacement rod 72 to move outward from the rectangular hole 37. Since the displacement of the displacement rod 72 is limited, the excess elastic force is converted into rotational force, causing the displacement rod 72 to rotate. During the rotation of the displacement rod 72, the drive rod 33 is driven to rotate, thus allowing the valve disc 1 to actively reset.

[0058] In a specific embodiment, such as Figure 6 The connecting ring 36 includes a socket 361, a guide groove 362, a hemispherical hole 363, a six-sided hole 364, and a ring body 365. The ring body 365 has a six-sided hole 364 in the middle and a plurality of sockets 361 on the outer surface of the ring body 365. The guide grooves 362 are arranged in pairs and are opened on the side wall of the socket 361. One end of the guide groove 362 extends to the side surface of the ring body 365, and the other end of the guide groove 362 is connected to the hemispherical hole 363, which is located on the inner wall of the socket 361. The hexagonal prism of the drive rod 33, in conjunction with the six-sided facet 364, drives the connecting ring 36 to rotate. This also allows the connecting ring 36 to be disassembled. The insertion hole 361 is designed for the movement of the round rod 42, while the guide groove 362 is used to guide the movement of the hemisphere 45, so that the hemisphere 45 is buffered before entering the hemisphere hole 363. At the same time, the guide groove 362 can ensure that the hemisphere 45 can smoothly enter the guide groove 362 for extraction when the drive assembly 4 is removed. Without the guide groove 362, the hemisphere 45 may get stuck when the round rod 42 is pulled out.

[0059] In a specific embodiment, such as Figures 7-8The drive assembly 4 includes a counterweight 41, a round rod 42, a connecting hole 43, a nut 44, a hemisphere 45, a translation rod 46, a return spring 47, a displacement hole 48, and a baffle 49. The round rod 42 has an external thread structure on its surface, and a nut 44 is sleeved on the outside of the external thread structure. The nuts 44 are arranged in pairs, and a number of counterweights 41 are installed between the two nuts 44. The counterweights 41 are sleeved on the outside of the round rod 42. The connecting hole 43 is opened at the end of the round rod 42, and a displacement hole 48 is opened on the side wall of the connecting hole 43. The translation rod 46 is driven and connected in the displacement hole 48. The two ends of the translation rod 46 are respectively connected to the hemisphere 45 and the baffle 49. The return spring 47 is installed between the two baffles 49. The gravity generated by the counterweight 41 can move the circular rod 42, which is driven and mounted on the tilting assembly 3, downward, thereby causing the connecting ring 36 to rotate. The displacement hole 48 is used to make the translation rod 46 translate. The translation rod 46 will make the hemisphere 45 move in and out of the displacement hole 48. The counterweight 41 is clamped between the two nuts 44 through the cooperation of the external thread structure. This setting can not only determine the position of the counterweight 41 according to the different installation positions of the explosion-proof valve, but also adjust the counterweight 41 according to the different insertion positions of the circular rod 42. The weight of the hemisphere 45, through the large contact area between the hemisphere 45 and the hemisphere hole 363, and the pressure converted from the elastic force of the return spring 47, results in greater friction between the hemisphere 45 and the hemisphere hole 363. This makes it difficult for the round rod 42 to slide freely out of the insertion hole 361, and the return spring 47 is always kept in a compressed state. The baffle 49 is used to limit the outward extension of the hemisphere 45. The two baffles 49 can also keep the spring in a compressed state. Maintaining the compressed state can continuously provide pressure and ensure the stability of the drive assembly 4 when connected to the flip assembly 3.

[0060] In a specific embodiment, such as Figure 9 The first reset assembly 2 includes a gear component 21, a rack 22, a cylinder 23, a connector 24, and a moving rod 25. The connector 24 is mounted on the outer surface of the mounting housing 5. The cylinder 23 and the gear component 21 are mounted on the surface of the connector 24. The moving rod 25 is drivenly connected in the cylinder 23. The end of the moving rod 25 is connected to the rack 22, which meshes with the gear component 21. When the push block 32 rotates, it gradually drives the moving rod 25 to move. When the moving rod 25 moves, the rack 22 will move. The displacement of the rack 22 will drive the gear 212 to rotate. The rotation of the gear 212 will cause the torsion spring 211 to be compressed. When the drive assembly 4 is removed, the torsion spring 211 drives the gear 212 to rotate in the opposite direction, thereby causing the rack 22 to move in the opposite direction and pushing the moving rod 25 back. During the pushing process of the moving rod 25, the push block 32 is driven to rotate in the opposite direction, thereby completing the reset of the valve disc 1.

[0061] In a specific embodiment, such as Figure 10 The gear component 21 includes a torsion spring 211, a gear 212, a push rod 213, and a limiting block 214. The gear 212 is meshed with the side of the rack 22. The push rod 213 is mounted on the surface of the gear 212, and the limiting block 214 is mounted on the other end of the push rod 213. A cylinder 242 is mounted on the connecting member 24. A displacement groove is formed in the cylinder 242, extending to the surface of the connecting member 24. The limiting block 214 is connected in transmission within the cylinder 242. A limiting ring 241 is installed in the displacement groove. The torsion spring 211 is sleeved on the outside of the push rod 213 and is installed between the gear 212 and the surface of the connecting member 24. The cylinder 242 is designed to allow the push rod 213 to make slight displacements, thus ensuring that the torsion spring 211 will not break when it generates elastic force. The cooperation between the limiting block 214 and the limiting ring 241 limits the degree of displacement of the push rod 213 to a certain extent.

[0062] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
