Description

Technical Field

[0001] This application relates to the technical field of exhaust valves, and in particular, to an exhaust valve with a pressure monitoring function. Background Art

[0002] The core function of a water pipe exhaust valve is to remove excess gas in the pipeline, maintain the stable operation of the system, and prevent air blockage and pipeline damage. A water pipe exhaust valve is a key device for controlling and regulating the gas pressure in a pipeline or container. Its main function is to discharge excess gas or inhale air to maintain the pressure balance of the system, ensuring the stability of fluid transportation and the safety of equipment.

[0003] Traditional exhaust valves mainly achieve the function of automatic exhaust through a float mechanism or a mechanical spring. Therefore, the exhaust valve can only achieve the function of automatic exhaust under specific pressure conditions. In the actual use process of pipelines, the pressure conditions in different pipelines are inconsistent, and the pressure in the pipeline is also constantly fluctuating. Therefore, traditional exhaust valves have poor adaptability and cannot monitor the specific situation of pressure changes in the pipeline in real time, resulting in low efficiency of subsequent pipeline maintenance and fault diagnosis, and there are deficiencies. Summary of the Invention

[0004] In order to improve the problems existing in traditional exhaust valves, this application provides an exhaust valve with a pressure monitoring function.

[0005] The exhaust valve with a pressure monitoring function provided by this application adopts the following technical solutions: An exhaust valve with a pressure monitoring function, comprising a valve body with a hollow interior. An air inlet and an air outlet are provided on the valve body. A controller is arranged on the valve body. A connecting pipe is arranged at the air inlet of the valve body and is used for connecting with a water pipe. A guide post with a polygonal cross-section is arranged inside the valve body. A lifting pipe and a floating ring are sequentially sleeved on the guide post from top to bottom in a sliding manner. A pressure sensor and a liquid level sensor are sequentially arranged on the lifting pipe from top to bottom. A pressure sensor is arranged on one side of the floating ring facing the lifting pipe. The pressure sensor, the liquid level sensor and the pressure sensor are all electrically connected to the controller. A power supply assembly for supplying power to the controller is arranged on the valve body. A floating box is arranged on the floating ring in a vertical sliding manner. A floating groove for the floating box to slide is provided on the floating ring. A plurality of convex top blocks are circumferentially arranged at intervals along the axis of the floating ring at the air inlet of the valve body, and the convex top blocks are used for abutting against the top of the floating ring. A connecting rod is arranged between the floating box and the lifting pipe. The outer diameter of the floating ring is smaller than the inner diameter of the connecting pipe. An anti-disengagement plate for supporting the floating ring is arranged on the connecting pipe. The outer diameter of the floating ring is larger than the diameter of the air inlet. A flow control member is arranged between the anti-disengagement plate and the floating ring, and the flow control member is used for controlling the flow rate of air or liquid flowing between the anti-disengagement plate and the floating ring. A speed control assembly is arranged on the floating box, and the speed control assembly is used for weakening the impact force of the floating ring on the valve body. A liquid blocking assembly is arranged on the valve body, and the liquid blocking assembly is used for preventing liquid from flowing out of the valve body.

[0006] By adopting the above technical solution, the power supply assembly supplies power to the controller. When air appears in the water pipe, under the speed regulation of the flow control member, the air is discharged outside the water pipe in the order of the connecting pipe, the gap between the floating box and the connecting pipe, the air inlet, the interior of the valve body and the air outlet, so as to reduce the influence of the air on the water flow in the water pipe. During this process, the indexes of the pressure sensor and the liquid level sensor hardly change, while the air pressure sensor detects the dynamic change of the air pressure in the water pipe. When the water in the water pipe flows into the connecting pipe, the buoyancy of the water will cause the floating box to slide. The sliding floating box drives the lifting pipe to rise through the connecting rod. The lifting pipe is separated from the sensing end of the pressure sensor, and the index of the pressure sensor changes until the guide post abuts against the floating ring. As the liquid level in the connecting pipe continuously rises, and the floating box pushes the floating ring to abut against the convex top block at the air inlet of the valve body, the liquid level in the connecting pipe will enter the valve body until the liquid level sensor on the lifting pipe is triggered. At this time, the liquid blocking assembly will prevent the liquid in the valve body from flowing out through the air outlet. During this process, the air pressure sensor feeds back the air pressure change caused by the liquid level in the water pipe. Thus, it is convenient for the maintenance personnel to monitor the specific situation of the pressure change in the water pipe in real time through the controller, thereby improving the efficiency of subsequent pipeline maintenance and fault diagnosis.

[0007] Optionally, the power supply component includes an inner tube disposed on the guide post, the inner tube is used to be placed inside a water pipe, a protective box is provided on the valve body, the controller is disposed inside the protective box, one end of the guide post facing away from the inner tube communicates with the protective box, an inner tube is coaxially and rotatably disposed on the inner side wall of the inner tube, a rotor is coaxially sleeved on the outer side wall of the inner tube, a plurality of vanes are circumferentially and uniformly arranged on the inner side wall of the inner tube, a stator opposite to the rotor is provided on the inner side wall of the inner tube, a wire is connected between the stator and the controller, a wire passing hole for the wire to pass through is formed in the guide post along its length direction, and a waterproof member for sealing is provided between the inner tube and the inner tube.

[0008] By adopting the above technical solution, after the worker installs the valve body on the water pipe through the connecting pipe, one end of the guide post will bring the inner tube into the water pipe at this time. When the water in the water pipe is being transported, the flowing water will flow through the inner diameter of the inner tube and impact the vanes. At this time, the vanes will drive the inner tube to rotate under the action of the water flow, and the rotating inner tube will drive the rotor to rotate synchronously. At this time, the coil on the stator will be cut by the magnetic induction lines on the rotor, and the current generated by the stator will be transmitted to the controller through the wire, so that the air pressure sensor, the liquid level sensor, and the pressure sensor are all powered on. During this process, there is no need for the worker to additionally set up lines, which is beneficial to reducing the equipment input cost.

[0009] Optionally, the waterproof member includes a retaining ring detachably disposed at the end of the inner tube, a bearing is provided between the end of the inner tube and the retaining ring, and sealing rings are provided between the inner tube and the retaining ring and between the end of the inner tube and the retaining ring.

[0010] By adopting the above technical solution, the possibility that the water in the water pipe flows into the space between the stator and the rotor and causes equipment damage is reduced, which is beneficial to improving the stability of power supply to the controller.

[0011] Optionally, the flow control member includes a convex ring disposed on the anti - detachment plate, a plurality of thin partition plates are provided on the floating ring, the plurality of thin partition plates are circumferentially and uniformly distributed along the axis of the floating ring, there is a spacing between adjacent two thin partition plates, and the thin partition plates are used to abut against the convex ring.

[0012] By adopting the above technical solution, during the process that the air in the water pipe flows into the connecting pipe, the air flows through the spacing between adjacent two thin partition plates. Under the action of the gravity of the floating ring, the floating ring will not slip at this time and the air flows through normally. When the water in the water pipe flows into the connecting pipe, the spacing between adjacent two thin partition plates will greatly hinder the flow of water. The water pressure will lift the floating ring, and as the water flows into the connecting pipe, the buoyancy of the floating box will gradually overcome the gravity of the floating ring, and the floating ring will drive the thin partition plates away from the convex ring on the anti - detachment plate. At this time, the water can flow into the connecting pipe quickly.

[0013] Optionally, the speed control component includes a rubber ring bladder sleeved on the floating box. A bladder groove for accommodating the rubber ring bladder is formed on the circumferential outer side wall of the floating box. A buffer ring is slidably sleeved on the bladder groove of the floating box. A buffer rod is arranged on a side of the buffer ring facing away from the rubber ring bladder. The buffer rod is used to abut against the inner top wall of the floating groove of the floating ring. When the floating ring abuts against the convex top block and the buffer ring squeezes the rubber ring bladder, the rubber ring bladder abuts against the inner side wall of the connecting pipe. A flow discharging member is arranged on the connecting rod. The flow discharging member is used to slowly release the pressure between the inside of the valve body and the connecting pipe.

[0014] By adopting the above technical solution, when the floating ring abuts against the convex top block, the buffer rod at this time will abut against the inner top wall of the floating groove of the floating ring. Under the action of the flow discharging member, the pressure at the bottom of the floating box is slowly released, so the water pressure from the water pipe is slowly released. Therefore, the pressure at the bottom of the floating box is continuously increasing, and the floating box continues to rise. Under the blocking action of the buffer ring, the rubber ring bladder is squeezed and deformed. The deformed rubber ring bladder will abut against the inner side wall of the connecting pipe, thereby reducing the possibility of the water pressure in the water pipe quickly diffusing into the valve body.

[0015] Optionally, one end of the connecting rod facing away from the lifting pipe penetrates through the lower surface of the floating box. The flow discharging member includes a vertical groove formed at the bottom of the connecting rod and a horizontal groove formed on the outer side wall of the connecting rod. The horizontal groove is communicated with the vertical groove. When the rubber ring bladder abuts against the inner side wall of the connecting pipe, the horizontal groove is located above the floating ring.

[0016] By adopting the above technical solution, after the deformed rubber ring bladder abuts against the inner side wall of the connecting pipe, at this time, the water pressure in the connecting pipe can only flow into the valve body in the order of the vertical groove and the horizontal groove, so that the liquid level in the valve body slowly rises, thereby providing sufficient time for the corresponding liquid level sensor. At the same time, the air subsequently flowing into the water pipe can enter the valve body through the vertical groove and the horizontal groove, so that the valve body in this state can still realize the function of exhausting air.

[0017] Optionally, the inner bottom wall of the floating box is provided with a gas collecting plate with a cross section in an inverted V shape. The vertical groove at the bottom of the connecting rod is communicated with the V-shaped concave side of the gas collecting plate.

[0018] By adopting the above technical solution, it is convenient for the subsequent air in the water pipe to quickly enter the valve body through the vertical groove and the horizontal groove, and then be discharged outside the valve body.

[0019] Optionally, the liquid-blocking assembly includes a top plate sleeved on the guide post. An installation ring plate is provided on the inner side wall of the valve body. A limiting ring pipe is provided on the installation ring plate. An air-permeable conical ring is provided between the limiting ring pipe and the top plate. A plurality of air-permeable holes are circumferentially formed in the air-permeable conical ring along its axis. The diameter of the air-permeable conical ring gradually decreases in the direction from the installation ring plate to the top plate. An internal resistance ring pipe is provided on the lifting pipe. An elastic ring film is provided between the internal resistance ring pipe and the installation ring plate. The diameter of the internal resistance ring pipe gradually decreases in the direction from the installation ring plate to the top plate. A plurality of overflow holes are circumferentially formed in the internal resistance ring pipe along its axis. A locking member is provided on the top plate. The locking member is used to fix the internal resistance ring pipe on the air-permeable conical ring. When the circumferential outer side wall of the internal resistance ring pipe abuts against the circumferential inner side wall of the limiting ring pipe, the air-permeable holes are staggered from the overflow holes.

[0020] By adopting the above technical solution, when the floating box does not slide, the air flowing into the connecting pipe will flow into the valve body in the order of the air inlet, the overflow holes, and the air-permeable holes on the limiting ring pipe. When the deformed rubber ring capsule abuts against the inner side wall of the connecting pipe, the air flowing into the connecting pipe will flow into the valve body in the order of the vertical groove, the horizontal groove, the air inlet, the overflow holes, and the air-permeable holes on the limiting ring pipe. During the rising process of the lifting pipe, the elastic ring film is continuously stretched, and the water is restricted within the elastic ring film. After the liquid level sensor is triggered, the locking member fixes the internal resistance ring pipe on the air-permeable conical ring. Since the air-permeable holes are staggered from the overflow holes, the air in the limiting ring pipe cannot be discharged at this time, and the liquid level in the limiting ring pipe gradually cannot rise, thus achieving the function of preventing the water in the water pipe from flowing out of the valve body.

[0021] Optionally, the locking member includes an electromagnet provided on the top plate and electrically connected to the controller, and a permanent magnet is provided on the lifting pipe.

[0022] By adopting the above technical solution, after the liquid level sensor is triggered, the controller activates the electromagnet. The electromagnet adsorbs the permanent magnet, and the permanent magnet drives the lifting pipe to continue rising. During this process, the elastic ring film continues to be stretched, and at the same time, the rubber ring capsule continues to be squeezed and deformed.

[0023] Optionally, a storage battery and a wireless transmission module are provided in the protection box, and both the storage battery and the wireless transmission module are electrically connected to the controller.

[0024] By adopting the above technical solution, it is convenient for maintenance personnel to remotely monitor, reduces the difficulty for maintenance personnel to perform sequential inspections, facilitates the targeted maintenance work of maintenance personnel, and improves the work efficiency of maintenance personnel.

[0025] In summary, the present application includes at least one of the following beneficial technical effects: 1. The power supply component powers the controller. When air appears in the water pipe, under the speed regulation of the flow control component, the air is discharged outside the water pipe in the order of the connecting pipe, the gap between the floating box and the connecting pipe, the air inlet, the inside of the valve body, and the air outlet, so as to reduce the influence of the air on the water flow in the water pipe. During this process, the indexes of the pressure sensor and the liquid level sensor hardly change, while the air pressure sensor detects the dynamic change of the air pressure in the water pipe. When the water in the water pipe flows into the connecting pipe, the buoyancy of the water will cause the floating box to slide. The sliding floating box drives the lifting pipe to rise through the connecting rod. The lifting pipe is separated from the sensing end of the pressure sensor, and the index of the pressure sensor changes until the guide post abuts against the floating ring. As the liquid level in the connecting pipe continuously rises, and the floating box pushes the floating ring to abut against the convex top block at the air inlet of the valve body, the liquid level in the connecting pipe will enter the valve body until the liquid level sensor on the lifting pipe is triggered. At this time, the liquid blocking component will prevent the liquid in the valve body from flowing out through the air outlet. During this process, the air pressure sensor feeds back the air pressure change caused by the liquid level in the water pipe. Thus, it is convenient for the maintenance personnel to monitor the specific situation of the pressure change in the water pipe in real time through the controller, thereby improving the efficiency of subsequent pipeline maintenance and fault diagnosis; 2. During the process of the air in the water pipe flowing into the connecting pipe, the air flows through the spacing between two adjacent thin partition plates. Under the action of the gravity of the floating ring, the floating ring will not slide at this time, and the air flows through normally. When the water in the water pipe flows into the connecting pipe, the spacing between two adjacent thin partition plates will greatly hinder the flow of water. The water pressure will lift the floating ring, and as the water flows into the connecting pipe, the buoyancy of the floating box will gradually overcome the gravity of the floating ring, and the floating ring will drive the thin partition plate away from the convex ring on the anti-disconnection plate. At this time, the water can flow into the connecting pipe quickly; 3. When the deformed rubber ring capsule abuts against the inner side wall of the connecting pipe, at this time, the water pressure in the connecting pipe can only flow into the valve body in the order of the vertical groove and the horizontal groove, so that the liquid level in the valve body rises slowly, providing enough time for the corresponding liquid level sensor, and at the same time, the air flowing into the water pipe subsequently can enter the valve body through the vertical groove and the horizontal groove, so that the valve body in this state can still realize the function of exhausting air.

[0034] Referring to Figure 2 and Figure 3 , a floating box 14 is arranged on the floating ring 9 in a vertically sliding manner. A floating groove 15 for the floating box 14 to slide is formed on the floating ring 9. At the air inlet 3 of the main body 021 and circumferentially spaced along the axis of the floating ring 9, a plurality of convex top blocks 16 are welded. The convex top blocks 16 are used to abut against the top of the floating ring 9.

[0035] Referring to Figure 2 and Figure 3 , a chassis plate 26 is welded to the bottom of the lifting pipe 8. A connecting rod 17 is welded between the floating box 14 and the chassis plate 26. One end of the connecting rod 17 facing away from the chassis plate 26 penetrates to the lower surface of the floating box 14. The outer diameter of the floating ring 9 is smaller than the inner diameter of the connecting pipe 6. An anti - detachment plate 18 for supporting the floating ring 9 is welded on the connecting pipe 6. The outer diameter of the floating ring 9 is larger than the diameter of the air inlet 3.

[0036] Referring to Figure 2 and Figure 3 , a power supply assembly 13 for powering the controller 5 is arranged on the valve body 2. The power supply assembly 13 includes an inner pipe 131 welded on the guide post 7. The inner pipe 131 is used to be placed in the water pipe 1. A storage battery 23 and a wireless transmission module 24 are arranged in the protection box 132. Both the storage battery 23 and the wireless transmission module 24 are electrically connected to the controller 5. One end of the guide post 7 facing away from the inner pipe 131 is communicated with the protection box 132.

[0037] Referring to Figure 2 and Figure 3 , an inner pipe 133 is coaxially rotatably arranged on the inner side wall of the inner pipe 131. A rotor 134 is coaxially sleeved on the outer side wall of the inner pipe 133. A plurality of blades 135 are circumferentially and evenly welded on the inner side wall of the inner pipe 133. The blades 135 are helical around the axis of the inner pipe 133. A stator 136 opposite to the rotor 134 is arranged on the inner side wall of the inner pipe 131. A wire 137 is connected between the stator 136 and the controller 5.

[0038] Referring to Figure 2 and Figure 3 , a wire passing hole 138 for the wire 137 to pass through is formed along the length direction of the guide post 7. A waterproof member 139 for sealing is arranged between the inner pipe 131 and the inner pipe 133. The waterproof member 139 includes an anti - detachment ring 1391 bolted to the end of the inner pipe 131. A bearing 1392 is arranged between the end of the inner pipe 133 and the anti - detachment ring 1391. Sealing rings 1393 are arranged between the inner pipe 131 and the anti - detachment ring 1391, and between the end of the inner pipe 133 and the anti - detachment ring 1391. The sealing rings 1393 are made of rubber materials.

[0039] The worker first extends the inner tube 131 to the water pipe 1 through the guide post 7, and then fixes the valve body 2 on the water pipe 1 through the connecting pipe 6. When the water in the water pipe 1 flows, a part of the flowing water will flow through the inner diameter of the inner tube 133. During the flow of the water, the water flow will impact the spiral blade 135.

[0040] The blade 135 will drive the inner tube 133 to rotate, and the rotating inner tube 133 will drive the rotor 134 to rotate synchronously. The magnetic induction lines on the rotor 134 will continuously cut the coil on the stator 136, and the current generated on the stator 136 will be transmitted along the wire 137 to the controller 5. The controller 5 distributes the current to the air pressure sensor 10, the liquid level sensor 11, the pressure sensor 12, the storage battery 23 and the wireless transmission module 24.

[0041] Refer to Figure 2 and Figure 3 , a flow control member 19 is arranged between the anti - detachment plate 18 and the floating ring 9. The flow control member 19 is used to control the flow rate of air or liquid flowing between the anti - detachment plate 18 and the floating ring 9. The flow control member 19 includes a convex ring 191 welded to the anti - detachment plate 18. A plurality of thin partition plates 192 are welded to the floating ring 9. The plurality of thin partition plates 192 are evenly distributed circumferentially along the axis of the floating ring 9. There is a spacing between adjacent two thin partition plates 192, and the thin partition plates 192 are used to abut against the convex ring 191.

[0042] Refer to Figure 2 and Figure 3 , a speed control assembly 20 is arranged on the floating box 14. The speed control assembly 20 is used to weaken the impact force of the floating ring 9 on the valve body 2. The speed control assembly 20 includes a rubber ring bladder 201 sleeved on the floating box 14. A bladder groove 202 for accommodating the rubber ring bladder 201 is opened on the circumferential outer side wall of the floating box 14. A buffer ring 203 is slidably sleeved on the bladder groove 202 of the floating box 14, and a buffer rod 204 is welded on the side of the buffer ring 203 facing away from the rubber ring bladder 201.

[0043] Refer to Figure 2 and Figure 3 , the buffer rod 204 is used to abut against the inner top wall of the floating groove 15 of the floating ring 9. When the floating ring 9 abuts against the convex top block 16 and the buffer ring 203 squeezes the rubber ring bladder 201, the deformed rubber ring bladder 201 abuts against the inner side wall of the connecting pipe 6. A drainage member 205 is arranged on the connecting rod 17. The drainage member 205 is used to slowly release the pressure between the inside of the valve body 2 and the connecting pipe 6.

[0044] Refer to Figure 2 and Figure 3, the drainage member 205 includes a vertical groove 2051 formed at the bottom of the connecting rod 17 and a horizontal groove 2052 formed on the outer sidewall of the connecting rod 17. The horizontal groove 2052 communicates with the vertical groove 2051. An air-gathering plate 22 with an inverted V-shaped cross-section is integrally formed on the inner bottom wall of the floating box 14. The vertical groove 2051 at the bottom of the connecting rod 17 communicates with the V-shaped concave side of the air-gathering plate 22. When the rubber ring capsule 201 abuts against the inner sidewall of the connecting pipe 6, the horizontal groove 2052 is located above the floating ring 9.

[0045] When the air in the water pipe 1 enters the connecting pipe 6, the air will flow through the gap between two adjacent thin partition plates 192. At the same time, under the gravity of the floating ring 9, the floating ring 9 will not slip at this time, and the index feedback by the pressure sensor 12 hardly changes, and the air flows normally, and the air pressure sensor 10 detects the dynamic change of the air pressure in the water pipe 1.

[0046] When the water in the water pipe 1 flows into the connecting pipe 6, due to the very small gap between two adjacent thin partition plates 192, the backflow is greatly hindered, and the water pressure will lift the floating ring 9. The floating ring 9 will drive the thin partition plate 192 away from the convex ring 191 on the anti-disconnection plate 18. At this time, the water can quickly flow into the connecting pipe 6, and as the water continuously flows into the connecting pipe 6, the buoyancy of the floating box 14 will gradually overcome its own gravity.

[0047] The floating box 14 will continuously rise. At this time, the floating box 14 pushes the lifting pipe 8 to rise through the connecting rod 17 and the chassis plate 26. The chassis plate 26 gradually moves away from the sensing end of the pressure sensor 12, and the index feedback by the pressure sensor 12 changes. As the floating box 14 continues to rise until the buffer rod 204 hits the inner top wall of the floating groove 15 of the floating ring 9, under the buoyancy of the rubber ring capsule 201, the floating box 14 drives the floating ring 9 to rise until the floating ring 9 abuts against the convex top block 16.

[0048] As the water pressure in the connecting pipe 6 continuously increases, the floating box 14 continues to rise. The floating box 14 drives the rubber ring capsule 201 to continuously squeeze the buffer ring 203. The rubber ring capsule 201 deforms and gradually abuts against the inner sidewall of the connecting pipe 6 until the floating box 14 stops rising. At this time, the horizontal groove 2052 is located above the floating ring 9, and the water below the floating ring 9 flows into the upper part of the floating ring 9 through the vertical groove 2051 and the horizontal groove 2052.

[0049] Refer to Figure 2 and Figure 3, a liquid-blocking component 21 is arranged on the valve body 2. The liquid-blocking component 21 is used to prevent liquid from flowing out of the valve body 2. The liquid-blocking component 21 includes a top plate 211 sleeved on the guide post 7. An installation ring plate 212 is integrally formed on the inner side wall of the main body 021. A limiting ring pipe 213 is bolted to the installation ring plate 212. The diameter of the limiting ring pipe 213 gradually decreases along the direction from the installation ring plate 212 to the top plate 211. A ventilation cone ring 214 is welded between the limiting ring pipe 213 and the top plate 211. A plurality of ventilation holes 215 are circumferentially formed on the ventilation cone ring 214 along its axis.

[0050] Referring to Figure 2 and Figure 3 , the diameter of the ventilation cone ring 214 gradually decreases along the direction from the installation ring plate 212 to the top plate 211. An internal resistance ring pipe 216 is welded on the lifting pipe 8. An elastic ring membrane 217 is arranged between the internal resistance ring pipe 216 and the installation ring plate 212. The elastic ring membrane 217 is made of elastic rubber material. The diameter of the internal resistance ring pipe 216 gradually decreases along the direction from the installation ring plate 212 to the top plate 211. A plurality of overflow holes 218 are circumferentially formed on the internal resistance ring pipe 216 along its axis.

[0051] Referring to Figure 2 and Figure 3 , a locking member 219 is arranged on the top plate 211. The locking member 219 is used to fix the internal resistance ring pipe 216 on the ventilation cone ring 214. The locking member 219 includes an electromagnet 2191 bolted to the top plate 211 and electrically connected to the controller 5. A permanent magnet 2192 is bolted to the lifting pipe 8. When the circumferential outer side wall of the internal resistance ring pipe 216 abuts against the circumferential inner side wall of the limiting ring pipe 213, the ventilation holes 215 and the overflow holes 218 are staggered.

[0052] The water flowing out from the transverse groove 2052 will enter the elastic ring membrane 217. The liquid level in the elastic ring membrane 217 continuously rises. The air in the elastic ring membrane 217 flows to the inside of the valve body 2 in the order of the overflow holes 218 and the ventilation holes 215, and is finally discharged through the exhaust pipe 25 until the liquid level sensor 11 is triggered. At this time, the controller 5 activates the electromagnet 2191. The electromagnet 2191 attracts the permanent magnet 2192, and the permanent magnet 2192 drives the lifting pipe 8 to continue rising.

[0053] The elastic ring membrane 217 is stretched again, and at the same time, the rubber ring capsule 201 is squeezed again until the circumferential outer side wall of the internal resistance ring pipe 216 abuts against the circumferential inner side wall of the ventilation cone ring 214. As the liquid level continues to rise, the elastic ring membrane 217 continues to deform until the elastic ring membrane 217 abuts against the circumferential inner side wall of the limiting ring pipe 213. At this time, under the constraint of the limiting ring pipe 213, the liquid level in the elastic ring membrane 217 cannot continue to rise.

[0054] At this time, the liquid level inside the elastic ring membrane 217 is located below the air pressure sensor 10. The air pressure sensor 10 feeds back the pressure change at this time when the pressure sensor 12 is triggered to the controller 5. The worker receives the pressure change value at all times through the wireless transmission module 24. At the same time, the air flowing into the water pipe 1 subsequently will continue to flow into the elastic ring membrane 217 along the horizontal groove 2052 and the vertical groove 2051 on the connecting rod 17, so that the water inside the elastic ring membrane 217 is continuously drained back into the water pipe 1 until the liquid level sensor 11 stops being triggered. At this time, the controller 5 stops powering the electromagnet 2191, the lifting pipe 8 descends, and the air inside the elastic ring membrane 217 is discharged in time.

[0055] The implementation principle of an exhaust valve with a pressure monitoring function in an embodiment of the present application is as follows: The worker first extends the built-in pipe 131 into the water pipe 1 through the guide post 7, and then fixes the valve body 2 on the water pipe 1 through the connecting pipe 6. When the water in the water pipe 1 flows, a part of the flowing water flows through the inner diameter of the inner pipe 133, and during the flowing process of the water, the water flow impacts the spiral blade 135.

[0056] The blade 135 drives the inner pipe 133 to rotate, and the rotating inner pipe 133 drives the rotor 134 to rotate synchronously. The magnetic induction lines on the rotor 134 continuously cut the coils on the stator 136, and the current generated on the stator 136 is transmitted to the controller 5 along the wire 137. The controller 5 distributes the current to the air pressure sensor 10, the liquid level sensor 11, the pressure sensor 12, the storage battery 23, and the wireless transmission module 24.

[0057] When the air in the water pipe 1 enters the connecting pipe 6, the air flows through the spacing between two adjacent thin partition plates 192. At the same time, under the action of the gravity of the floating ring 9, the floating ring 9 does not slip at this time, and the index feedback by the pressure sensor 12 hardly changes, and the air flows through normally. The air pressure sensor 10 detects the dynamic change of the air pressure in the water pipe 1.

[0058] When the water in the water pipe 1 flows into the connecting pipe 6, since the spacing between two adjacent thin partition plates 192 is very small, the backflow is greatly hindered, and the water pressure lifts the floating ring 9. The floating ring 9 drives the thin partition plate 192 away from the convex ring 191 on the anti-disengagement plate 18. At this time, the water can quickly flow into the connecting pipe 6, and as the water continuously flows into the connecting pipe 6, the buoyancy of the floating box 14 gradually overcomes its own gravity.

[0059] The floating box 14 continuously rises. At this time, the floating box 14 pushes the lifting pipe 8 to rise through the connecting rod 17 and the chassis plate 26. The chassis plate 26 gradually moves away from the sensing end of the pressure sensor 12, and the index feedback by the pressure sensor 12 changes. As the floating box 14 continues to rise until the buffer rod 204 hits the inner top wall of the floating groove 15 of the floating ring 9, under the buoyancy of the rubber ring bladder 201, the floating box 14 drives the floating ring 9 to rise until the floating ring 9 abuts against the convex top block 16.

[0060] As the water pressure in the connecting pipe 6 continuously increases, the floating box 14 continues to rise. The floating box 14 drives the rubber ring bladder 201 to continuously squeeze the buffer ring 203. The rubber ring bladder 201 deforms and gradually abuts against the inner side wall of the connecting pipe 6 until the floating box 14 stops rising. At this time, the transverse groove 2052 is located above the floating ring 9, and the water below the floating ring 9 flows into the upper part of the floating ring 9 through the vertical groove 2051 and the transverse groove 2052.

[0061] The water flowing out of the transverse groove 2052 will enter the elastic ring membrane 217. The liquid level in the elastic ring membrane 217 continuously rises. The air in the elastic ring membrane 217 flows to the valve body 2 in the order of the overflow hole 218 and the ventilation hole 215, and is finally discharged by the exhaust pipe 25 until the liquid level sensor 11 is triggered. At this time, the controller 5 activates the electromagnet 2191. The electromagnet 2191 attracts the permanent magnet 2192, and the permanent magnet 2192 drives the lifting pipe 8 to continue rising.

[0062] The elastic ring membrane 217 is stretched again, and at the same time, the rubber ring bladder 201 is squeezed again until the circumferential outer side wall of the internal resistance ring pipe 216 abuts against the circumferential inner side wall of the ventilation cone ring 214. As the liquid level continues to rise, the elastic ring membrane 217 continues to deform until the elastic ring membrane 217 abuts against the circumferential inner side wall of the limit ring pipe 213. At this time, under the constraint of the limit ring pipe 213, the liquid level in the elastic ring membrane 217 cannot continue to rise.

[0063] At this time, the liquid level in the elastic ring membrane 217 is located below the air pressure sensor 10. The air pressure sensor 10 feeds back the pressure change from the moment the pressure sensor 12 is triggered to this time to the controller 5. The worker receives the pressure change value through the wireless transmission module 24 at all times. At the same time, the subsequent air flowing into the water pipe 1 will continue to flow into the elastic ring membrane 217 along the transverse groove 2052 and the vertical groove 2051 on the connecting rod 17, so that the water in the elastic ring membrane 217 is continuously drained back into the water pipe 1 until the liquid level sensor 11 stops being triggered. At this time, the controller 5 stops powering the electromagnet 2191, the lifting pipe 8 descends, and the air in the elastic ring membrane 217 is discharged in time.

[0064] The above are all the preferred embodiments of this application. The protection scope of this application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
