Description

Technical Field

[0001] This invention relates to the field of exhaust valve technology, and in particular to a combined exhaust valve that is adaptive in angle and automatically exhausts air. Background Technology

[0002] In industrial fluid transport, HVAC, and water supply and drainage systems, air vents are key components for ensuring stable system operation. They need to release the gas accumulated in the pipeline in a timely manner to avoid problems such as reduced transport efficiency, pipeline corrosion, and equipment damage caused by air blockage.

[0003] Existing traditional exhaust valves mostly adopt a single fixed exhaust structure, and the exhaust port angle cannot be flexibly adjusted. In complex pipeline layout scenarios, it is difficult to adapt to the connection requirements of different directions. During installation, additional auxiliary components such as elbows and adapters are required, which not only increases the installation cost and space occupation, but also easily creates new leakage risks at the transition points.

[0004] Meanwhile, traditional exhaust valves often have an integrated exhaust component design, which lacks adaptive pressure relief regulation capability. When the gas pressure in the pipeline fluctuates greatly, it is easy to cause untimely or excessive exhaust, affecting the system pressure stability.

[0005] In addition, although some combined exhaust valves are equipped with multiple exhaust channels, the sealing of the connection structure of each channel is insufficient, and jamming and misalignment are prone to occur when adjusting the exhaust angle, making it impossible to achieve precise angle positioning. The response speed of its pressure relief components is slow, making it difficult to quickly adjust the exhaust efficiency according to changes in air pressure, and thus failing to meet the requirements of high-precision fluid systems. Summary of the Invention

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. This invention, by setting a tightly fitting first and second outer shell at the upper end of the base, and configuring a first connector and a second connector at the front end of each, and correspondingly rotatably installing a first L-shaped pipe, a second L-shaped pipe, a connector, and an exhaust pipe, achieves multi-dimensional adaptive adjustment of the exhaust angle. The first retaining rings at both ends of the first L-shaped pipe can rotate in the first annular groove of the first rotating seat and the first auxiliary groove of the first connector, respectively. With the rotational connection between the first rotating head and the first rotating head, the first exhaust pipe can be driven to complete full-angle adjustment. The structure on the second outer shell side is similar, effectively solving the problems of fixed exhaust angle and poor adaptability of traditional exhaust valves.

[0024] 2. This invention employs a dual-exhaust structure with a first outer shell and a second outer shell. The two exhaust channels are independent and can work synchronously. Compared with the traditional single-channel exhaust valve, the exhaust efficiency is more than doubled. The first T-shaped hole in the first connector is connected to the first vent pipe, and the second T-shaped hole in the second connector is connected to the second vent pipe. This allows for the rapid exhaust of gas from different areas in the pipeline simultaneously, avoiding the gas accumulation problem when exhausting through a single channel. At the same time, the dual-channel structure can serve as a backup for each other. When one exhaust component fails, the other can still maintain basic exhaust operation, ensuring the continuous and stable operation of the system. This solves the problems of low exhaust efficiency and poor fault tolerance of traditional exhaust valves, and is suitable for fluid transportation systems with high flow rates and high pressures.

[0025] 3. In this invention, pressure relief components are installed both inside and outside the first and second outer shells. A servo motor drives the gear ring to rotate, causing the sealing plates of the annular array to slide along the hexagonal groove. This allows for precise control of the opening and closing of the exhaust channel. Simultaneously, the pressure relief rod inside the upper guide rod achieves dynamic pressure stabilization and exhaust under the combined action of the second spring and air pressure. Compared to the passive exhaust mode of traditional exhaust valves, this pressure relief component can actively respond to changes in air pressure, avoiding untimely or excessive exhaust. This effectively improves the problems of slow pressure relief response and poor pressure stabilization effect of traditional exhaust valves, and effectively enhances the pressure stability and operational safety of the fluid system.

[0045] 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.

[0046] Please see Figures 1 to 13 The present invention provides a technical solution:

[0047] An adaptive angle and automatic exhaust valve includes a base 1. A first housing 2 is fixedly installed on the upper end of the base 1 near the left side. A first connector 201 is fixedly installed on the front end face of the first housing 2. A first T-shaped hole 202 is formed inside the first connector 201. Figure 3 and Figure 4 As shown, the first T-shaped hole 202 allows air to pass through the left and right ends and the upper surface of the first connector 201. Figure 4 As shown, a first vent pipe 203 is fixedly installed at the right end of the first connector 201. The interior of the first vent pipe 203 is a hollow structure, and a through-hole is opened on its circumferential surface, communicating with the right end of the first T-shaped hole 202. Figure 4 As shown, during use, external gas can enter the interior of the first T-shaped hole 202 through the first vent pipe 203.

[0048] Secondly, a first rotating seat 204 is fixedly installed on the upper end face of the first connector 201. The upper end face of the first rotating seat 204 is open to the interior and communicates with the upper end of the first T-shaped hole 202 for ventilation. Then, a first annular groove 205 is formed inside the first rotating seat 204. Next, a first connecting seat 208 is provided above the first connector 201. The left side face of the first connecting seat 208 is a hollow structure, and a first auxiliary groove 209 is formed on its inner circumferential surface. Figure 5 As shown, a first L-shaped pipe 206 is provided between the first rotating seat 204 and the first connecting seat 208. First retaining rings 207 are fixedly installed on the outer circumferential surfaces of both the upper and lower ends of the first L-shaped pipe 206. The lower first retaining ring 207 is rotatably installed inside the first annular groove 205, while the upper first retaining ring 207 is rotatably installed inside the first auxiliary groove 209. Figure 5 As shown.

[0049] Therefore, during use, the first L-shaped pipe 206 rotates, causing the first connecting seat 208 to rotate synchronously. When the first L-shaped pipe 206 is not rotating, the first connecting seat 208 can rotate. This operational state allows adjustment of the orientation of the upper end of the first L-shaped pipe 206 and the orientation of the first connecting seat 208. Furthermore, the rotation of the first connecting seat 208 can change the orientation of the subsequent first exhaust pipe 215, such as... Figure 5 As shown.

[0050] It should be noted that a sealing rubber device is provided between the first retaining ring 207, the first annular groove 205, and the first auxiliary groove 209 to prevent gas leakage. The material is made using special techniques, such as molding, to form a uniform and dense sealing layer on the contact surface between the rubber and the first retaining ring 207. At the same time, nano-level fumed silica filler is added inside the rubber to improve elasticity and wear resistance. The thickness of the rubber device is precisely calculated to perfectly match the depth of the first annular groove 205 and the first auxiliary groove 209. When the first L-shaped pipe 206 rotates, the rubber device can slide synchronously with the retaining ring, so that it will not cause jamming due to excessive thickness, nor will it cause sealing failure due to excessive thinness.

[0051] In addition, the surface of the rubber device is treated with plasma to enhance its adhesion to the metal parts, preventing it from falling off after long-term rotation. This ensures a continuous and stable sealing effect and prevents gas leakage from the rotation gap, which could affect the working efficiency of the exhaust valve.

[0052] Secondly, a first connecting ring 210 is fixedly installed on the lower outer end face of the first connecting seat 208. An external thread is formed on the outer circumferential surface of the first connecting ring 210 (it should be noted that both ends of the first connecting ring 210 are through-holes to allow gas to flow out from inside the first connecting seat 208). A first rotating head 211 is rotatably installed on the outer circumferential surface of the first connecting ring 210. A first internal thread 212 is formed on the inner circumferential surface of the upper end of the first rotating head 211, thus enabling it to be rotatably connected to the first connecting ring 210. A first rotating head 213 is rotatably installed on the outer lower end of the first rotating head 211. A first connecting groove 214 is formed on the inner circumferential surface of the first rotating head 213, and the lower end of the first rotating head 211 is rotatably installed inside the first connecting groove 214. Figure 5 As shown (it should be noted that a rubber device is also provided between the outer side of the first rotating head 211 and the inner wall of the first connecting groove 214, and its device is the same as the above-mentioned device, used to prevent gas leakage), and a first air outlet pipe 215 is fixedly installed on the outer side of the first rotating head 213. The first air outlet pipe 215 and the first rotating head 213 are connected for gas flow, such as... Figure 5 As shown.

[0053] Therefore, during use, when the first connecting seat 208 rotates, it will cause the first rotating head 211 to rotate synchronously, thereby adjusting the position of the subsequent first rotating head 213. Then, through the rotational connection between the first rotating head 211 and the first connecting groove 214, the first rotating head 213 can rotate 360 ​​degrees. Therefore, through the cooperation of the above structure, the orientation of the first air outlet pipe 215 can be easily adjusted, thus making it suitable for pipes in different directions.

[0054] Additionally, a second outer shell 3 is fixedly installed on the upper surface of the first base 1 near the right side. A second connector 301 is fixedly installed at the front end of the second outer shell 3. A second T-shaped hole 302 is opened inside the second connector 301. A second vent pipe 303 is fixedly installed at the front end of the second connector 301. The end of the second vent pipe 303 adjacent to the first vent pipe 203 is fixedly connected, allowing gas to enter the interior of the second vent pipe 303 and then into the interior of the second T-shaped hole 302, such as... Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown.

[0055] A second rotating seat 304 is fixedly installed on the upper end face of the second connector 301. A second annular groove 305 is provided inside the second rotating seat 304. A second connecting seat 308 is provided above the second rotating seat 304. A second auxiliary groove 309 is provided inside the second connecting seat 308. A second L-shaped pipe 306 is provided between the second rotating seat 304 and the second connecting seat 308. A second retaining ring 307 is fixedly installed on the outer circumferential surface of both the upper and lower ends of the second L-shaped pipe 306. The lower second retaining ring 307 is rotatably installed inside the second annular groove 305, and the upper second retaining ring 307 is rotatably installed inside the second auxiliary groove 309.

[0056] Secondly, a second connecting ring 310 is fixedly installed on the outer side of the second connecting seat 308. A second rotating head 311 is rotatably installed on the outer side of the second connecting ring 310. A second internal thread 312 is opened on the inner circumferential surface of the upper end of the second rotating head 311. An external thread is opened on the outer side of the second connecting ring 310 for rotatably connecting with the second internal thread 312.

[0057] A second rotating head 313 is rotatably mounted on the outer side of the lower end of the second rotating head 311. A second connecting groove 314 is formed on the inner circumferential surface of the second rotating head 313, and the lower end of the second rotating head 311 is rotatably mounted inside the second connecting groove 314. A second air outlet pipe 315 is fixedly mounted on the outer side of the second rotating head 313. Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown.

[0058] It should be noted that the structure and function of the second outer shell 3 connection are the same as those of the first outer shell 2 connection, therefore, they will not be described again.

[0059] A connecting box 401 is fixedly installed at the rear end of both the first outer casing 2 and the second outer casing 3. A battery storage box 402 is fixedly installed at the rear end of the interior of both the first outer casing 2 and the second outer casing 3, and an electromagnetic ring 403 is fixedly installed at the middle position. (It should be noted that a baffle is fixedly installed near the rear end of the interior of both the first outer casing 2 and the second outer casing 3, and the rear end of the electromagnetic ring 403 is fixedly installed on the baffle.) Figure 6 As shown), a guide rod 404 is fixedly installed inside the electromagnetic ring 403 and at the front end of the baffle. A first spring 405 is fixedly installed at the front end of the guide rod 404. A venting blocking rod 406 is fixedly installed at the end of the first spring 405 away from the guide rod 404. (It should be noted that the end of the venting blocking rod 406 away from the first spring 405 extends into the interior of the adjacent first T-shaped hole 202 and second T-shaped hole 302 under the action of the first spring 405 to achieve gas blocking. However, the end of the venting blocking rod 406 away from the first spring 405 is open to the interior, and the circumferential surface of the end near the first spring 405 is also open to the interior. Therefore, an L-shaped airflow hole is opened on the circumferential surface of the venting blocking rod 406 from the end away from the first spring 405 to the interior and then to the outer circumferential surface.) Figure 8 As shown, the end of the vent plug rod 406 near the first spring 405 is recessed and slidably mounted on the outer circumferential surface of the guide rod 404. This ensures that the vent plug rod 406 can slide along the path of the guide rod 404 without tilting, thus ensuring the stable sliding of the vent plug rod 406.

[0060] Therefore, with the cooperation of the above structures, during use, when no work is being performed, the first spring 405 is in a naturally extended state, pushing the front end of the venting blocking rod 406 into the first T-shaped hole 202 and the second T-shaped hole 302 to block the gas and prevent it from entering the interior of the first L-shaped pipe 206 and the second L-shaped pipe 306, thereby effectively sealing the gas passage and preventing gas leakage.

[0061] When the operation is in progress, the solenoid ring 403 receives a signal from the connection box 401. At this time, with the battery box 402 connected to the external motor, the electromagnetic force generated by the solenoid ring 403 will attract the vent block rod 406 to slide towards the guide rod 404, compressing the first spring 405.

[0062] At this time, the front end of the venting plug rod 406 disengages from the blocking positions of the first T-shaped hole 202 and the second T-shaped hole 302, and the gas flows into the interior of the subsequent first L-shaped pipe 206 and the second L-shaped pipe 306. Then, under the action of the above structure, it is transported to the corresponding pipe through the action of the first vent pipe 215 and the second vent pipe 315. At this time, since the gas is under normal pressure, the subsequent pressure relief component 7 will not operate.

[0063] Then, a retaining ring 701 from the pressure relief assembly 7 is fixedly installed on the inner wall of the first outer shell 2 and the second outer shell 3, and on the outer side of the vent blockage rod 406. (The retaining ring 701 has a circular through hole extending from its inner surface to its upper end face.) Figure 9 As shown), a lower air guide rod 702 is fixedly installed on the top of the fixed ring 701, and a housing ring 703 is fixedly installed on the top of the lower air guide rod 702. A servo motor 704 is fixedly installed inside the housing ring 703, and a drive gear 705 is fixedly installed on the output shaft of the servo motor 704. An mounting ring cavity 706 is fixedly installed inside the housing ring 703. It should be noted that the lower end face of the mounting ring cavity 706 is open to the interior for gas flow. A gear ring 708 is rotatably mounted inside the mounting ring cavity 706, and six auxiliary sliding plates 707 are fixedly installed on the upper circumferential surface inside. The auxiliary sliding plates 707 are inclined, and grooves are formed from the upper end face to the lower end face. Figure 13 As shown.

[0064] Then, the gear ring 708 and the drive gear 705 mesh with each other, and the upper and lower ends of the center position of the gear ring 708 are in a continuous state, with a hexagonal groove 709 formed on the upper end. Six sealing plates 710 are evenly arranged in a ring array between the gear ring 708 and the auxiliary slide plate 707. A slide rod 711 is fixedly installed at the center of the outer straight line of the upper end face of each sealing plate 710. The upper end of the slide rod 711 is slidably installed inside the auxiliary slide plate 707, while the lower end face is slidably installed in the corresponding groove of the hexagonal groove 709 at the straight corner. Six sliders 712 correspond to each straight slide groove in the hexagonal groove 709, such as... Figure 13 As shown.

[0065] An upper air guide rod 713 is fixedly installed at the upper end of the outer casing ring 703. The upper air guide rod 713 has a first air outlet 714 evenly arranged in a ring array from its outer side to its inner side. A filter screen 715 is fixedly installed inside the first air outlet 714. It should be noted that the diameter from the middle to the top of the upper air guide rod 713 is slightly larger than the diameter from the middle to the bottom. Figure 11 As shown, a rubber pad 716 is fixedly installed near the position, and a pressure relief rod 717 is slidably installed inside the upper air guide rod 713 and below the rubber pad 716. Pressure relief holes 718 are evenly arranged in a ring array from the outer side to the inner side of the upper end of the pressure relief rod 717, and a compression ring 719 is fixedly installed on the outer circumferential surface of the upper end. A second spring 720 is fixedly installed between the top and the inner upper end of the upper air guide rod 713. Figure 11 As shown.

[0066] Therefore, during use, pressure sensors are installed inside the first L-shaped pipe 206 and the second L-shaped pipe 306 to sense the gas pressure inside the pipe in real time.

[0067] At this time, the internal pressure is too high, and the pressure sensor will send a signal to the corresponding servo motor 704. The output shaft of the servo motor 704 drives the drive gear 705 to rotate. The drive gear 705 drives the gear ring 708 to rotate. When the gear ring 708 rotates, it will drive the slider 712 to move. When the slider 712 moves, it will drive the sealing plate 710 to rotate. With the cooperation of the slide rod 711 and the auxiliary slide plate 707, the diameter of the sealing plate 710 is opened. At this time, the gas will enter the interior of the lower air guide rod 702 through the vent block rod 406, and then pass through the gear ring 708 to enter the interior of the upper air guide rod 713. At this time, the gas pressure increases, pushing the pressure relief rod 717 to slide upward, so that the second spring 720 is compressed.

[0068] When the pressure relief hole 718 moves to the working state, the gas inside it will flow out and then flow out through the first vent hole 714. After the pressure inside the pipe returns to normal, the working steps described above are reversed to complete the sealing of the gas flow, thereby realizing automatic pressure relief.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
