Description

Technical Field

[0001] This invention relates to the technical field of valve equipment, and specifically to a pipeline valve assembly for industrial production. Background Technology

[0002] Currently, pipeline equipment is primarily used for the flow and discharge of gases and liquids. For flue gas ducts, due to the chimney effect of hot flue gas, smoke spreads rapidly in the event of a fire. Fire dampers in pipelines are typically installed on ventilation equipment ducts and are normally open. In the event of a fire, they automatically close when the gas temperature inside the duct reaches a certain level or the smoke concentration reaches a certain threshold, thus interrupting the flow of smoke and preventing the spread of fire. To ensure timely response and valve closure, sensors are often incorporated into the valve structure to detect changes in temperature or smoke and control valve closure accordingly.

[0003] In related technologies, sensor structures are mostly installed inside pipes. When the sensor needs to be repaired, replaced, or the battery needs to be replaced, disassembly is very inconvenient, resulting in a waste of time and manpower. Summary of the Invention

[0021] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0022] like Figures 1-5 As shown in the figure, this application provides a pipeline valve assembly for industrial production, characterized in that it includes: a base plate 2, a mounting plate 3, and a sensor 4.

[0023] The base plate 2 is detachably connected to the pipe 1. A mounting plate 3 is mounted on the base plate 2, and a mounting groove is provided on the mounting plate 3. A valve body 31 is installed in the mounting groove. An actuator 32 is mounted on the mounting plate 3, and the actuator 32 controls the opening and closing of the valve body 31. The sensor 4 is electrically connected to the actuator 32 and is detachably connected to the mounting plate 3. A positioning element for fixing the sensor 4 is provided on the base plate 2. A through hole 10 for the sensor 4 to pass through is provided on the base plate 2. A movable plate 5 is provided on the base plate 2, and the movable plate 5 can be movably mounted on the base plate 2 to block or open the through hole 10. A driving element for moving the movable plate 5 is provided on the base plate 2.

[0024] In this embodiment, the sensor 4 in the valve assembly is detachably mounted on the mounting plate 3. The through hole 10 on the base plate 2 can be opened by the driving component, and the sensor 4 and the mounting plate 3 can be disassembled by the positioning component. The sensor 4 can be taken out through the through hole 10 for maintenance, replacement and other operations, which effectively improves the efficiency of sensor 4 disassembly and installation.

[0025] The sensor 4 includes a body and a temperature sensor. In some embodiments, the sensor 4 also includes a smoke sensor. The collected data is transmitted to the control module, which controls the actuator 32 to operate in order to control the valve body 31 to open or close.

[0026] The structure of the driving component and the positioning component in the embodiments of this application is described below: The base plate 2 has a movable groove 21, in which a movable plate 5 is movably installed. The base plate 2 also has a first transverse groove 23. A driving component includes a movable rod 22 movably installed in the first transverse groove 23, one end of which is connected to the movable plate 5 to drive it to move along the movable groove 21. The base plate 2 also has a driving groove 24, in which a first piston 61 is movably installed. The driving groove 24 communicates with the first transverse groove 23. A second piston 62 is located at the end of the movable rod 22. The base plate 2 also has a control groove 29, in which the first piston 61 is connected to a driving rod 6. The short plate of the driving rod 6 extends into the control groove 29. A first turntable 8 is located in the control groove 29, with a first arc-shaped groove 81 on it. A driving block that mates with the first arc-shaped groove 81 is located at the end of the driving rod 6. The first turntable 8 drives the driving rod 6 to move.

[0027] The first turntable 8 in the control slot 29 cooperates with the drive rod 6 through the first arc-shaped slot 81. When the first turntable 8 rotates, it acts on the drive rod 6 through the arc-shaped slot, causing the drive rod 6 to move horizontally. The drive rod 6 drives the first piston 61 to move. The first piston 61 changes the air pressure in the drive slot 24 and the first transverse slot 23. The air pressure acts on the second piston 62, thereby driving the movable rod 22 to move horizontally. When the movable rod 22 moves, it can drive the movable plate 5 to move horizontally, thereby realizing the opening and closing of the through hole 10. The through hole 10 is closed during normal use, and the through hole 10 is opened when the sensor 4 needs to be installed or removed, so as to facilitate the installation and removal of the through hole 10.

[0028] For example, a second turntable 9 is also provided in the control groove 29. The second turntable 9 has a second arc-shaped groove 91. A limit rod 92 is provided in the control groove 29. The limit rod 92 is movably installed in the base plate 2. One end of the limit rod 92 is provided with a driving block that cooperates with the second arc-shaped groove 91. The second turntable 9 drives the limit rod 92 to move. The other end of the limit rod 92 extends to the outside of the base plate 2. The inner wall of the pipe 1 is provided with a limit hole 93 that cooperates with the end of the limit rod 92. A guide rod 7 is provided in the control groove 29. The guide rod 7 passes through the first turntable 8 and the second turntable 9. The axes of the guide rod 7, the first turntable 8, and the second turntable 9 coincide. The guide rod 7 is movably installed in the control groove 29 and moves along the axis of the guide rod 7. A guide groove is provided on the guide rod 7. Holes for the guide rod 7 to pass through are opened on the first turntable 8 and the second turntable 9. A locking block that cooperates with the guide groove is provided on the hole.

[0029] The guide rod 7 within the control slot 29 drives the first turntable 8 and the second turntable 9. The holes on the first and second turntables 8 and 9 engage with the guide rod 7. When the guide rod 7 moves vertically, it drives the first and second turntables 8 and 9, converting the linear motion of the guide rod 7 into circumferential rotation of the first and second turntables 8 and 9. As mentioned earlier, when the first turntable 8 rotates, it drives the movable rod 22 and the movable plate 5. When the second turntable 9 rotates, it drives the limiting rod 92 to move horizontally through the second arc-shaped groove 91. When the end of the limiting rod 92 engages with the limiting hole 93, it limits the movement between the base plate 2 and the pipe 1. When the end of the limiting rod 92 separates from the limiting hole 93, it separates the base plate 2 from the pipe 1. For example, to ensure the sealing of the pipe 1, a sealing gasket (not shown in the figure) is provided at the connection between the base plate 2 and the pipe 1. For example, the first turntable 8 is located above the second turntable 9.

[0030] The base plate 2 is provided with an electric push rod 74 that drives the guide rod 7 to move. The guide groove includes a first guide groove 71, a second guide groove 72 and a third guide groove 73. The second guide groove 72 is bent in the direction of bending along the length of the guide rod 7 and towards the circumference of the guide rod 7. The first guide groove 71 and the third guide groove 73 are provided along the length of the guide rod 7.

[0031] When the electric actuator 74 is in operation, it drives the guide rod 7, causing the guide rod 7 to move vertically along its own axis, thereby engaging with the first turntable 8 and the second turntable 9 through the guide groove. The guide groove is divided into a first guide groove 71, a second guide groove 72, and a third guide groove 73. The first guide groove 71 and the third guide groove 73 are linear grooves. When the first turntable 8 or the second turntable 9 engages with the first guide groove 71 or the third guide groove 73, the movement of the guide rod 7 will not drive the corresponding turntable. Only when the second guide groove 72 engages with the first turntable 8 and the second turntable 9 will it drive the first turntable 8 and the second turntable 9. Furthermore, since the entire base plate 2 does not need to be disassembled when disassembling and installing sensor 4, and only the second guide groove 72 is bent, the first turntable 8 and the second turntable 9 cannot rotate simultaneously. When the second guide groove 72 on the guide rod 7 engages with the first turntable 8, it can drive the movable rod 22 and the movable plate 5 to move. However, at this time, the third guide groove 73 engages with the second turntable 9 and cannot drive the limit rod 92; the end of the limit rod 92 still engages with the pipe 1. When the second guide groove 72 on the guide rod 7 engages with the second turntable 9, it can drive the limit rod 92. At this time, the first guide groove 71 engages with the first turntable 8 and will not drive the movable rod 22.

[0032] For example, a vertical groove 42 is provided on the base plate 2, and the positioning component includes a positioning rod 41 disposed in the vertical groove 42. The top of the positioning rod 41 extends to the outside of the base plate 2. A notch 33 communicating with the vertical groove 42 is provided on the mounting plate 3. A sensor 4 is disposed in the notch 33. A locking hole that cooperates with the end of the positioning rod 41 is provided at the bottom of the sensor 4. A first reset component 43 is connected to the bottom of the positioning rod 41. A second transverse groove 25 is provided inside the base plate 2. A transverse rod 26 is movably installed in the second transverse groove 25. A first magnet 27 is provided at the top of the first piston 61. A second magnet 28 is provided at the end of the transverse rod 26 away from the positioning rod 41. The magnetic properties of the first magnet 27 and the second magnet 28 are opposite on the sides that are close to each other. An opening is provided on the positioning rod 41. An inclined slope is provided at the top of the opening. The inclined slope is inclined from top to bottom in a direction away from the transverse rod 26.

[0033] Among them, a receiving groove 34 is provided on one side of the notch 33, and a reset plate 35 is movably installed in the receiving groove 34. One end of the reset plate 35 is connected to a second reset member 36, and the other end abuts against the sensor 4. One end of the second reset member 36 is connected to the inner wall of the receiving groove 34, and the other end is connected to the reset plate 35.

[0034] The positioning rod 41 is movably installed in the vertical slot 42 and driven by the horizontal rod 26. A second magnet 28 is provided at the end of the horizontal rod 26, and a first magnet 27 is provided on the first piston 61. When the first piston 61 moves, the horizontal rod 26 moves horizontally under the action of magnetic force. After the horizontal rod 26 moves away from the positioning rod 41, it separates from the positioning rod 41. Under the action of the first reset member 43, the positioning rod 41 moves downward, and the top of the positioning rod 41 separates from the locking hole on the sensor 4. Under the action of the reset plate 35, the sensor 4 pops out from the mounting plate 3, facilitating disassembly. Furthermore, when the first piston 61 moves, it simultaneously drives the horizontal rod 26 and the movable rod 22. When the horizontal rod 26 moves away from the positioning rod 41, the movable rod 22 also drives the movable plate 5 to move, thereby opening the through hole 10, facilitating the removal of the sensor 4 for replacement, maintenance, or battery replacement.

[0035] The working principle of this application is explained below: Under normal circumstances, the movable plate 5 blocks the through hole 10 on the base plate 2. When it is necessary to disassemble the sensor 4, the electric push rod 74 will drive the guide rod 7 to move vertically downward. The third guide groove 73 on the guide rod 7 first contacts the first turntable 8, that is, the second guide groove 72 acts on the first turntable 8, driving the first turntable 8 to rotate. When the first turntable 8 rotates, it acts on the drive rod 6 through the first arc groove 81, causing the drive rod 6 to move horizontally. At the same time, the first piston 61 on the drive rod 6 will move and change the air pressure in the drive groove 24 and the first transverse groove 23, thereby causing the second piston 62 on the movable rod 22 and the movable rod 22 to move horizontally. When the movable rod 22 approaches the drive groove 24, it will drive the movable plate 5 to move and open the through hole 10. After the through hole 10 is opened, it is convenient to disassemble the sensor 4.

[0036] On the other hand, when the first piston 61 moves, the horizontal rod 26 is driven to move horizontally under the action of magnetic force. After the horizontal rod 26 moves away from the positioning rod 41, it will separate from the positioning rod 41. Under the action of the first reset member 43, the positioning rod 41 will move downward, and the top of the positioning rod 41 will separate from the locking hole on the sensor 4. Under the action of the reset plate 35, the sensor 4 will pop out from the mounting plate 3, thus facilitating disassembly. With the movement of the movable plate 5 to open the through hole 10, the sensor 4 can be disassembled smoothly.

[0037] If the base plate 2 needs to be disassembled, the drive guide rod 7 continues to move downwards, the second guide groove 72 cooperates with the second turntable 9, and when the second turntable 9 rotates, it will drive the limiting rod 92 to move horizontally through the second arc groove 91. When the end of the limiting rod 92 separates from the limiting hole 93, the base plate 2 and the pipe 1 can be separated, thus facilitating the disassembly of the entire base plate 2.

[0038] In summary, in the valve assembly of this application embodiment, the sensor 4 is detachably mounted on the mounting plate 3. The through hole 10 on the base plate 2 can be opened by the driving component, and the sensor 4 and the mounting plate 3 can be disassembled by the positioning component. The sensor 4 can be taken out through the through hole 10 for maintenance, replacement and other operations, which effectively improves the efficiency of sensor 4 disassembly and installation.
