Description

Technical Field

[0001] This invention relates to the field of remote-controlled butterfly valve technology, specifically to a remote-controlled butterfly valve with pressure detection function. Background Technology

[0002] In recent years, with the continuous development of the construction industry, the demand for transportation pipelines in various fields of the construction industry has been increasing. However, during the transportation of fluid media in the pipeline, the fluid media cannot be regulated and controlled in a timely manner, which causes many problems for construction workers.

[0003] A butterfly valve is a relatively simple regulating valve that can be used to control the switching of low-pressure pipeline media. Butterfly valves can be used to regulate and control the transport of various types of fluids such as water, steam, corrosive media, and oil, and play a role in throttling and shutting off in pipelines.

[0004] During use, existing butterfly valves may experience loosening at the connection between the valve plate and the valve seat due to the high flow rate and pressure of the fluid in the pipeline. This can lead to sealing problems and leakage. Furthermore, impurities in the fluid may damage the valve plate, significantly reducing the service life of the components. This not only affects the speed of the project but also increases labor costs. Summary of the Invention

[0005] The purpose of this invention is to provide a remote-controlled butterfly valve with pressure detection function to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a remote-controlled butterfly valve with pressure detection function.

[0007] like Figure 1As shown, the remote-controlled butterfly valve is positioned between the input pipe 9 and the output pipe 10. The remote-controlled butterfly valve includes a valve body 1, an automatic mechanism 2, a manual component 3, a detection mechanism 4, a drive mechanism 5, a sealing component 6, a damage-prevention component 7, and a valve seat 8. The valve body 1 contains the valve seat 8, and the valve body 1 is connected to the valve seat 8. The automatic mechanism 2 is mounted on the valve body 1, and the valve body 1 is connected to the automatic mechanism 2. The automatic mechanism 2 is connected to the valve seat 8. Multiple damage-prevention components 7 are mounted on the automatic mechanism 2, and the automatic mechanism 2 is fixedly connected to the damage-prevention components 7. A manual component 3 is located on one side of the automatic mechanism 2, and the automatic mechanism 2 is connected to the manual component 3. A detection mechanism 4 is located at the end of the valve body 1 near the input pipe 9, and a sealing component 6 is located at the end of the valve body 1 near the output pipe 10. A drive mechanism 5 is located above the sealing component 6, and the valve body 1 is connected to the drive mechanism 5. During the operation of the remote-controlled butterfly valve, the valve body 1 serves as the main mounting base, and liquid enters through the input pipe 9. Once inside the valve body 1, the automatic mechanism 2, with the valve seat 8 fixed, receives an electrical signal and remotely rotates to regulate the liquid flow and cut off the flow. The manual component 3 works in conjunction with the automatic mechanism 2 to manually operate the remote-controlled butterfly valve. The detection mechanism 4 detects the sealing function of the remote-controlled butterfly valve when the automatic mechanism 2 and the valve seat 8 are completely sealed. When the seal is intact, the detection mechanism 4 remains unchanged. When the detection mechanism 4 detects a leak, it sends an electrical signal to the drive mechanism 5. Upon receiving the signal, the drive mechanism 5 starts working, driving the sealing component 6 to rotate and seal the leaked liquid, preventing it from continuing to flow downstream and damaging other components. The anti-damage component 7 prevents the automatic mechanism 2 from being damaged when impurities in the liquid continue to be transported to the output pipe 10 through the automatic mechanism 2. This completes the entire working process of the remote-controlled butterfly valve.

[0008] like Figure 1 , 2As shown, the automatic mechanism 2 includes a drive motor 21, a valve stem 22, a first bevel gear 23, a valve plate 24, and a rubber ring 25. The drive motor 21 is mounted on the valve body 1 and connected to it. The valve stem 22 is mounted on the output end of the drive motor 21 and is connected to it. The valve body 1 is connected to the valve stem 22. The first bevel gear 23 is mounted on the end of the valve stem 22 near the drive motor 21 and is connected to it. The first bevel gear 23 meshes with the manual component 3. The valve plate 24 is mounted on the valve stem 22, and the valve stem 22 and valve plate 25 are connected. The valve plate 24 is fixedly connected to the anti-damage component 7 and to the valve seat 8. A rubber ring 25 is provided on the valve plate 24 and connected to the rubber ring 25. During the operation of the automatic mechanism 2, the drive motor 21 is the part that receives electrical signals and outputs power. The output end of the drive motor 21 drives the valve stem 22 to rotate. The valve stem 22 drives the first bevel gear 23 and the valve plate 24 to rotate together inside the valve body 1. A rubber ring 25 is installed on the valve plate 24. During the rotation of the valve plate 24, the rubber ring 25 is in close contact with the valve seat 8 to achieve the working effect of controlling the liquid flow and sealing.

[0009] like Figure 1 , 2 As shown in Figure 3, the manual component 3 includes a second bevel gear 31, a drive shaft 32, a fixed seat 33, and a handwheel 34. A fixed seat 33 is provided at the upper end of the valve body 1, and the valve body 1 is connected to the fixed seat 33. A drive shaft 32 is disposed inside the fixed seat 33, and the fixed seat 33 is rotatably connected to the drive shaft 32. A handwheel 34 is provided at one end of the drive shaft 32, and the drive shaft 32 is connected to the handwheel 34. A second bevel gear 31 is provided at the end of the drive shaft 32 away from the handwheel 34, and the drive shaft 32 is connected to the second bevel gear 31. The second bevel gear 31 is connected to the first bevel gear 31. When the bevel gear 23 meshes, and the automatic mechanism 2 malfunctions and cannot perform remote control operation via electrical signal, the manual component 3 can be manually operated to complete the work task. The handwheel 34 on the fixed base 33 is manually rotated. The rotation of the handwheel 34 drives the transmission shaft 32 to rotate. The transmission shaft 32 drives the second bevel gear 31 to rotate. The second bevel gear 31 can drive the first bevel gear 23. The rotation of the first bevel gear 23 drives the valve stem 22. The valve stem 22 drives the valve plate 24 to start rotating, thereby achieving the work effect of sealing and controlling the liquid flow.

[0010] like Figure 1 , 4As shown, the detection mechanism 4 includes a first housing 41, a slide rail 42, a movable plate 43, a pressure block 44, and a pressure testing machine 45. The valve body 1 is fitted with the first housing 41 near the input pipe 9, and the valve body 1 is connected to the first housing 41. The first housing 41 contains a slide rail 42, and the movable plate 43 is mounted on the slide rail 42, with the slide rail 42 and movable plate 43 slidably connected. The pressure testing machine 45 is mounted above the slide rail 42, and the first housing 41 is connected to the pressure testing machine 45. The pressure testing machine 45 is mounted on the pressure testing machine 45, with the pressure testing machine 45 and pressure block 44 slidably connected. During the operation of the detection mechanism 4, the automatic mechanism 2 and the valve seat 8 need to be completely sealed to prevent the liquid from the input pipe 9 from flowing through. It will be blocked inside the remote control butterfly valve. Under complete sealing, the pressure at every point in contact with the liquid is equal. At this time, the pressure will squeeze the moving plate 43 inside the first housing 41. The moving plate 43 moves upward on the slide 42 and squeezes the pressure block 44. The pressure block 44 is squeezed into the pressure detector 45. When the pressure is fixed, the pressure block 44 will also remain in one position. If the remote control butterfly valve leaks at this time, the liquid pressure will drop. The moving plate 43 will move downward on the slide 42 due to the decrease in pressure. The pressure block 44 will also extend due to the lack of squeezing. At this time, the pressure detector 45 will send an electrical signal to the drive mechanism 5 to achieve the detection effect.

[0011] like Figure 1 , 5 As shown in Figure 6, the drive mechanism 5 includes a second housing 51, a rotary motor 52, a drive shaft 53, and a gear 54. The valve body 1 is provided with a second housing 51 near the output pipe 10. The valve body 1 is connected to the second housing 51. The rotary motor 52 is provided inside the second housing 51. The second housing 51 is connected to the rotary motor 52. The output end of the rotary motor 52 is provided with a drive shaft 53. The output end of the rotary motor 52 is connected to the drive shaft 53. The gear 54 is provided on the drive shaft 53. The drive shaft 53 is connected to the gear 54. The gear 54 meshes with the sealing member 6. During the operation of the drive mechanism 5, the rotary motor 52 installed inside the second housing 51 receives an electrical signal sent by the pressure detector 45 and starts to start the output end to drive the drive shaft 53 to rotate. The rotation of the drive shaft 53 drives the gear 54 to rotate. The gear 54 drives the sealing member 6 to start working.

[0012] like Figure 1 , 5As shown in Figures 7, 8, 9, and 10, the sealing component 6 includes a rotating housing 61, a groove 62, a sliding groove 63, a round rod 64, a baffle 65, a fixed housing 66, a channel rail 67, and a groove block 68. The rotating housing 61 is located below the second outer shell 51 and is rotatably connected to the valve body 1. The surface of the rotating housing 61 has a groove 62 that meshes with the gear 54. Multiple sliding grooves 63 are provided on the rotating housing 61, and a round rod 64 is mounted on each sliding groove 63, slidably connected to the round rod 64. A baffle 65 is mounted on the round rod 64, connecting the round rod 64 to the baffle 65. A fixed housing 66 is located at the end of the rotating housing 61 furthest from the manual component 3, connecting the rotating housing 61 to the fixed housing 66. The fixed housing 66 is connected to the valve body 1. The fixed housing 66 is provided with a groove rail 67, and a groove block 68 is provided in the groove rail 67. The groove rail 67 and the groove block 68 are slidably connected. The baffle 65 is connected to the groove block 68. During the operation of the sealing component 6, the drive mechanism 5 needs to provide power. The gear 54 drives the groove 62 provided on the rotating housing 61. The rotating housing 61 drives the multiple sliding grooves 63 provided on itself to move. The sliding grooves 63 drive the round rod 64 to move. The round rod 64 drives the baffle 65 to move. The baffle 65 can close or open during the movement to seal the leaked liquid. The baffle 65 drives the groove block 68 on the groove rail 67 to move in the fixed housing 66 to complete the overall working requirements.

[0013] like Figure 1 , 2 As shown in Figure 11, the damage prevention component 7 includes a mounting housing 71, a spring 72, a telescopic rod 73, and damage prevention bristles 74. The mounting housing 71 is mounted on the valve plate 24 and is fixedly connected to it. A spring 72 is installed inside the mounting housing 71 and is connected to it. A telescopic rod 73 is attached to one end of the spring 72 and is slidably connected to the mounting housing 71. Several damage prevention bristles 74 are attached to the end of the telescopic rod 73 away from the spring 72 and are connected to it. During the rotation of the valve plate 24... The interior of valve body 1 will compress the telescopic rod 73 on part of the anti-damage component 7. After being compressed, the telescopic rod 73 will apply pressure to the spring 72 inside the mounting housing 71. The spring 72 will begin to shorten under pressure. The liquid may contain impurities, which may damage the surface of valve plate 24 during high-speed transportation. The function of anti-damage bristles 74 is to prevent impurities in the liquid from directly contacting valve plate 24. Anti-damage bristles 74 can block impurities, thus avoiding damage to valve plate 24 and fulfilling the work requirements.

[0014] like Figure 1 , 2As shown in Figure 11, the valve plate 24 is fixedly connected to the mounting housing 71. The fixed connection adopts a welding connection method because welding connection has higher connection strength and load-bearing capacity than keyed connection, threaded connection, riveted connection and other connection methods, and has a more stable function.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: 1. The present invention adopts a sealing component. During the operation of the sealing component, a drive mechanism is required to provide power. The gear drives the groove set on the rotating housing, the rotating housing drives the multiple sliding grooves set on it to move, the sliding grooves drive the round rod to move, the round rod drives the baffle to move, and the baffle can be closed or opened during the movement to seal the leaked liquid. The baffle drives the groove block on the groove rail to move in the fixed housing to complete the overall working requirements.

[0016] 2. This invention employs a damage-prevention component. During the rotation of the valve plate, the interior of the valve body will compress the telescopic rod on part of the damage-prevention component. After being compressed, the telescopic rod will apply pressure to the spring inside the mounting housing. The spring will begin to shorten under pressure. The liquid may contain impurities, which may damage the surface of the valve plate during high-speed transportation. The function of the damage-prevention component is to prevent impurities in the liquid from directly contacting the valve plate. The damage-prevention component can block impurities, thus avoiding damage to the valve plate and fulfilling the operational requirements. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] This invention provides a technical solution: A remote-controlled butterfly valve is placed between an input pipe and an output pipe. The remote-controlled butterfly valve includes a valve body, an automatic mechanism, a manual component, a detection mechanism, a drive mechanism, a sealing component, a damage-prevention component, and a valve seat. The valve body contains a valve seat, which is connected to the valve body. An automatic mechanism is mounted on the valve body, which is connected to the valve body. The automatic mechanism is connected to the valve seat. Multiple damage-prevention components are mounted on the automatic mechanism, which is fixedly connected to the damage-prevention components. A manual component is located on one side of the automatic mechanism, which is connected to the manual component. A detection mechanism is located at the end of the valve body near the input pipe. A sealing component is located at the end of the valve body near the output pipe. A drive mechanism is located above the sealing component. The valve body is rotatably connected to the sealing component and is connected to the drive mechanism. During operation, the valve body serves as the primary mounting base, and liquid enters through the input pipe. Inside the valve body, the automatic mechanism can receive electrical signals and remotely rotate while the valve seat is fixed, regulating the flow of liquid and cutting off its flow. The manual mechanism works in conjunction with the automatic mechanism to manually operate the remote-controlled butterfly valve. The detection mechanism can detect the sealing function of the remote-controlled butterfly valve when the automatic mechanism and the valve seat are completely sealed. When the seal is intact, the detection mechanism does not change. When the detection mechanism detects a leak, it sends an electrical signal to the drive mechanism. Upon receiving the signal, the drive mechanism starts working, driving the sealing component to rotate and seal the leaking liquid, preventing it from continuing to flow downstream and damaging other components. The anti-damage component prevents the automatic mechanism itself from being damaged when impurities in the liquid continue to be transported to the output pipeline through the automatic mechanism. This completes the entire working process of the remote-controlled butterfly valve.

[0020] The automatic mechanism includes a drive motor, a valve stem, a first bevel gear, a valve plate, and a rubber ring. The drive motor is mounted on the valve body and connected to it. A valve stem is mounted on the output end of the drive motor and is connected to the valve stem. The valve body is connected to the valve stem. A first bevel gear is mounted on the valve stem near the drive motor end, connecting the valve stem to the first bevel gear, which meshes with a manual component. A valve plate is mounted on the valve stem and connected to it. The valve plate is fixedly connected to a damage-prevention component and to a valve seat. A rubber ring is mounted on the valve plate and connected to it. During operation, the drive motor receives electrical signals and outputs power. Its output drives the valve stem to rotate, causing the first bevel gear and valve plate to rotate together inside the valve body. The rubber ring on the valve plate makes tight contact with the valve seat during rotation, achieving the effect of controlling liquid flow and sealing.

[0021] The manual component includes a second bevel gear, a drive shaft, a fixed base, and a handwheel. A fixed base is located at the upper end of the valve body, connecting the valve body to the fixed base. A drive shaft is located inside the fixed base, rotatably connecting the fixed base and the drive shaft. A handwheel is located at one end of the drive shaft, connecting the drive shaft to the handwheel. A second bevel gear is located at the end of the drive shaft furthest from the handwheel, connecting the drive shaft to the second bevel gear. The second bevel gear meshes with the first bevel gear. When the automatic mechanism malfunctions and cannot be remotely controlled by electrical signals, the manual component can be operated manually to complete the task. The handwheel on the fixed base is manually rotated, causing the drive shaft to rotate. The drive shaft then rotates the second bevel gear, which in turn rotates the first bevel gear. The rotation of the first bevel gear rotates the valve stem, which in turn rotates the valve plate, achieving the effect of sealing and controlling the liquid flow.

[0022] The testing mechanism includes a first housing, a slide rail, a movable plate, a pressure block, and a pressure testing machine. The first housing is located near the input pipe end of the valve body and is connected to the valve body. A slide rail is located inside the first housing, and a movable plate is mounted on the slide rail, with the slide rail and movable plate slidably connected. A pressure testing machine is located above the slide rail, and the first housing is connected to the pressure testing machine. A pressure block is mounted on the pressure testing machine, with the pressure testing machine and pressure block slidably connected. During the operation of the testing mechanism, the automatic mechanism and valve seat must be completely sealed. This ensures that the liquid delivered from the input pipe is blocked inside the remote-controlled butterfly valve. In a sealed state, the pressure at every point in contact with the liquid is equal. This pressure compresses the moving plate inside the first housing, causing it to move upwards on the slide and press against the pressure block. The pressure block is then forced into the pressure testing machine. When the pressure is constant, the pressure block remains stationary in one position. If the remote-controlled butterfly valve leaks, the liquid pressure will decrease. The moving plate will move downwards on the slide due to the reduced pressure, and the pressure block will extend out due to the lack of compression. At this point, the pressure testing machine will send an electrical signal to the drive mechanism to achieve the detection effect.

[0023] The drive mechanism includes a second housing, a rotary motor, a drive shaft, and gears. The second housing is located near the end of the valve body close to the output pipe, and the valve body is connected to the second housing. The rotary motor is located inside the second housing and is connected to the second housing. The drive shaft is located at the output end of the rotary motor and is connected to the drive shaft. Gears are mounted on the drive shaft and are connected to the gears. The gears mesh with the sealing component. During the operation of the drive mechanism, the rotary motor installed inside the second housing receives an electrical signal from the pressure testing machine and starts to start the output end, driving the drive shaft to rotate. The rotation of the drive shaft drives the gears to rotate, and the gears drive the sealing component to start working.

[0024] The sealing component includes a rotating housing, a groove, a sliding groove, a round rod, a baffle, a fixed housing, a rail, and a block. The rotating housing is located below the second housing and is rotatably connected to the valve body. The rotating housing surface has a groove that meshes with a gear. Multiple sliding grooves are provided on the rotating housing, and a round rod is mounted on each sliding groove, slidably connected to the rod. A baffle is mounted on the round rod and connected to it. A fixed housing is located at the end of the rotating housing away from the manual component, connecting the rotating housing and the fixed housing, which in turn connects to the valve body. A rail is provided on the fixed housing, and a block is mounted within it, slidably connected to the rail. The baffle is connected to the block. During operation, the sealing component requires a drive mechanism to provide power. The gear drives the groove on the rotating housing, which in turn moves the multiple sliding grooves. The sliding grooves move the round rod, which in turn moves the baffle. The baffle can close or open during movement to seal leaked liquid. The baffle moves the block on the rail within the fixed housing to fulfill the overall operational requirements.

[0025] The damage prevention components include a mounting housing, a spring, a telescopic rod, and damage prevention bristles. The mounting housing is fixedly connected to the valve plate. A spring is installed inside the mounting housing, and the mounting housing is connected to the spring. A telescopic rod is attached to one end of the spring, and the telescopic rod is slidably connected to the mounting housing. Several damage prevention bristles are located at the end of the telescopic rod away from the spring, and the telescopic rod is connected to the damage prevention bristles. During the rotation of the valve plate, the interior of the valve body will compress some of the telescopic rods on the damage prevention components. This compression will apply pressure to the spring inside the mounting housing, causing the spring to shorten. Since the liquid may contain impurities that could damage the surface of the valve plate during high-speed transport, the damage prevention bristles prevent these impurities from directly contacting the valve plate. The bristles block these impurities, thus avoiding damage to the valve plate and fulfilling the operational requirements.

[0026] The valve plate is fixedly connected to the mounting housing. The fixed connection adopts a welding connection method because welding has higher connection strength and load-bearing capacity than keyed connections, threaded connections, riveted connections, etc., and has a more stable function.

[0027] The working principle of this invention is as follows: During the operation of the remote-controlled butterfly valve, the valve body 1 serves as the main installation base. Liquid enters the valve body 1 through the input pipe 9. The automatic mechanism 2, under the fixed condition of the valve seat 8, receives an electrical signal and is remotely rotated to regulate the flow of liquid and cut off its flow. The manual component 3 works in conjunction with the automatic mechanism 2 to manually operate the remote-controlled butterfly valve. The detection mechanism 4 can detect the sealing function of the remote-controlled butterfly valve when the automatic mechanism 2 and the valve seat 8 are completely sealed. When the seal is intact, the detection mechanism 4 remains unchanged. When the detection mechanism 4 detects a leak, it sends an electrical signal to the drive mechanism 5. After receiving the electrical signal, the drive mechanism 5 starts working, driving the sealing component 6 to rotate and seal the leaked liquid, preventing it from continuing to flow downstream and damaging other components. The anti-damage component 7 prevents the automatic mechanism 2 from being damaged when impurities in the liquid continue to be transported to the output pipe 10 through the automatic mechanism 2. This completes the entire working process of the remote-controlled butterfly valve.
