DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Embodiment 1

[0038] The exhaust valve in the prior art has a simple structure and a certain exhaust capacity per unit time. When there is a lot of gas in the water pipeline, it is necessary to exhaust continuously for a long time, which not only affects the exhaust efficiency, but also causes great wear on the spring and seal inside the exhaust valve, thereby affecting the service life. In order to solve this technical defect in the prior art, Figure 1-Figure 5 As shown, this embodiment proposes a quick exhaust valve, which can change the exhaust capacity of the exhaust valve as the air pressure inside the valve body shell 1 changes. The upper end of the valve body shell 1 of the exhaust valve is detachably mounted with a sealing top plate 2, and the interior of the valve body shell 1 is provided with an automatic exhaust mechanism 3 capable of adjusting the exhaust rate, and the sealing top plate 2 is provided with an exhaust auxiliary mechanism 4 and a jet anti-blocking mechanism 5, and auxiliary installation mechanisms 6 for improving the stability of the exhaust valve are symmetrically arranged on both sides of the valve body shell 1. During the installation process, the auxiliary installation mechanism 6 can effectively improve the stability of the valve body shell 1. After the installation is completed, the automatic exhaust mechanism 3 can quickly exhaust the gas in the water pipeline, thereby preventing air from gathering in the pipeline to form air blockage.

[0039] In order to automatically discharge the gas in the water pipeline and prevent air blockage in the pipeline, the present embodiment is provided with an automatic exhaust mechanism 3. Specifically, the automatic exhaust mechanism 3 includes an exhaust channel 305 that runs through the sealing top plate 2. An exhaust circular pipe 301 is movably installed inside the exhaust channel 305. A bottom plate 302 is fixedly installed at the lower end of the exhaust circular pipe 301. A top flange 303 is arranged on the outer side of the upper end of the exhaust circular pipe 301. The diameter of the bottom plate 302 is larger than the diameter of the exhaust circular pipe 301. A spring telescopic rod 304 is fixedly installed on the inner side of the sealing top plate 2. The lower end of the spring telescopic rod 304 is fixedly connected to the bottom plate 302. The spring telescopic rod 304 is located on the outer side of the exhaust circular pipe 301, thereby ensuring that the exhaust circular pipe 301 can only It can slide up and down but cannot rotate. A float assembly 306 is fixedly installed on the bottom plate 302. The side wall of the exhaust pipe 301 is provided with a first exhaust hole 307, a second exhaust hole 308, and a third exhaust hole 309 from bottom to top. Initially, the bottom plate 302 is in close contact with the sealing top plate 2. At this time, the exhaust channel 305 is in a closed state. When the float assembly 306 moves downward, the exhaust pipe 301 will move downward synchronously. Next, the air in the valve body shell 1 will be discharged through the exhaust pipe 301. The aperture of the first exhaust hole 307 is smaller than that of the second exhaust hole 308, and the aperture of the second exhaust hole 308 is smaller than that of the third exhaust hole 309. As the exhaust pipe 301 gradually moves downward, the exhaust rate will gradually increase.

[0040] According to the above content, it can be known that during the operation of the exhaust valve, initially, the water in the water pipe will enter the interior of the valve body shell 1 from the bottom of the valve body shell 1, and then the float assembly 306 will move upward under the buoyancy of the water, thereby causing the exhaust circular pipe 301 to extend upward. At this time, the bottom plate 302 will be in a state of blocking the exhaust channel 305.

[0041] When there is gas in the water pipeline, the gas will enter the interior of the valve body shell 1 and overflow above the liquid surface. Moreover, as the gas pressure continues to increase, the water level inside the valve body shell 1 will gradually drop. Next, the exhaust pipe 301 will move toward the interior of the valve body shell 1 under the action of the gravity of the float assembly 306. Next, the gas inside the valve body shell 1 will be discharged outward through the exhaust hole on the exhaust pipe 301.

[0042] Moreover, if the amount of gas inside the valve body shell 1 is small, the downward movement of the exhaust pipe 301 will also be small. At this time, only the first exhaust hole 307 will move to the inside of the valve body shell 1. If the amount of gas inside the valve body shell 1 is large, the downward movement of the exhaust pipe 301 will also be large. At this time, the second exhaust hole 308 will also move to the inside of the valve body shell 1. If the amount of gas inside the valve body shell 1 is very large, the third exhaust hole 309 will also move to the inside of the valve body shell 1. The more the exhaust pipe 301 moves downward, the greater the exhaust rate, thereby realizing automatic adjustment of the exhaust rate.

[0043] In addition, if the water flow in the water pipe suddenly stops, the water level in the valve body shell 1 will drop rapidly. At this time, the three sets of exhaust holes will quickly connect with the interior of the valve body shell 1. Next, the outside air will quickly enter the interior of the water pipe through the exhaust holes, which can effectively avoid water hammer.

[0044] In this embodiment, the automatic exhaust mechanism 3 is provided, and the cooperation between the exhaust pipe 301 and the float assembly 306 is utilized, so that the gas in the water pipeline can be automatically discharged to prevent air blockage in the pipeline, and air can be automatically delivered to the pipeline when the water pipeline is cut off, which can avoid the water hammer phenomenon to a certain extent, thereby extending the service life of the water delivery system; moreover, in this embodiment, the automatic exhaust mechanism 3 is provided, and the cooperation between the first exhaust hole 307, the second exhaust hole 308 and the third exhaust hole 309 is utilized, so that the exhaust capacity of the exhaust valve can change with the change of the air pressure inside the valve body shell 1, which can ensure a sufficient exhaust rate at high pressure and effectively reduce the damage to the exhaust valve caused by long-term continuous exhaust.

[0045] Embodiment 2

[0046] In order to automatically and regularly scrape and clean the outer wall of the exhaust pipe 301 to prevent foreign particles from adhering to the outside of the exhaust pipe 301 and affecting the upward and downward movement of the exhaust pipe 301, based on the first embodiment, Figure 1 , Figure 3 as well as Figure 6-Figure 8As shown, the present embodiment is provided with an exhaust auxiliary mechanism 4, specifically, the exhaust auxiliary mechanism 4 comprises a circular annular groove 401 provided on the sealing top plate 2, a movable platform 402 is movably installed inside the circular annular groove 401, a driving assembly 403 for driving the movable platform 402 to rotate along the circular annular groove 401 is provided inside the sealing top plate 2, the driving assembly 403 comprises a movable gear ring movably installed on the inner wall of the circular annular groove 401, a driving gear meshing with the movable gear ring is movably installed inside the sealing top plate 2, the movable gear ring is fixedly connected to the movable platform 402, when the movable gear ring rotates under the action of the driving gear, the movable platform 402 is caused to reciprocate along the circular annular groove 401, a mounting bracket 404 is fixedly installed on the movable platform 402, a mounting box body 405 is detachably installed on the mounting bracket 404, a plastic scraper 406 in contact with the outer surface of the exhaust circular pipe 301 is fixedly installed on the mounting box body 405, 05 is the same as the length of the plastic scraper 406. The length of the installation box body 405 is less than the distance between the upper end of the third exhaust hole 309 and the top flange 303. When the third exhaust hole 309 moves to the inside of the valve body shell 1, there is still a gap between the upper end of the installation box body 405 and the top flange 303. A storage cavity 408 is opened inside the installation box body 405. The interior of the storage cavity 408 is filled with anti-stick grease 409. A rotating brush body 407 is movably installed at the opening of the storage cavity 408. When the movable platform 402 rotates periodically along the circular annular groove 401, the plastic scraper 406 will scrape and clean the outer surface of the exhaust pipe 301. A micro motor for driving the rotating brush body 407 is provided inside the installation box body 405. Initially, the bristle part of the rotating brush body 407 is located outside the installation box body 405. When the rotating brush body 407 rotates, the bristle part will pass through the inside of the storage cavity 408.

[0047] According to the above content, when the movable ring gear rotates under the action of the driving gear, the movable platform 402 will make periodic rotation along the circular ring groove 401. During the rotation of the movable platform 402, the plastic scraper 406 will scrape and clean the outside of the exhaust pipe 301, thereby preventing foreign particles from adhering to the outside of the exhaust pipe 301.

[0048] At the same time, the bristle part of the rotating brush body 407 will contact the outside of the exhaust circular tube 301, and, every certain period of time, the rotating brush body 407 will rotate one circle under the action of the micro motor. During the rotation, the bristle part of the rotating brush body 407 will contact the anti-stick grease 409 inside the storage cavity 408, so that a certain amount of anti-stick grease 409 adheres to the bristles.

[0049] Therefore, when the rotating brush body 407 contacts the exhaust pipe 301 , a layer of grease is applied to the outer side of the exhaust pipe 301 , thereby reducing the friction resistance between the exhaust pipe 301 and the exhaust channel 305 and improving the exhaust sensitivity.

[0050] In this embodiment, an exhaust auxiliary mechanism 4 is provided, and the cooperation between the driving component 403 and the plastic scraper 406 is utilized, so that the outer wall of the exhaust circular pipe 301 can be scraped and cleaned regularly and automatically to prevent foreign particles from adhering to the outside of the exhaust circular pipe 301 and affecting the up and down movement of the exhaust circular pipe 301, without the need for manual operation by the staff; moreover, in this embodiment, an exhaust auxiliary mechanism 4 is provided, and the cooperation between the rotating brush body 407 and the movable platform 402 is utilized, so that a layer of anti-stick grease 409 can be automatically applied to the outer surface of the exhaust circular pipe 301 while scraping and cleaning, thereby reducing the friction between the exhaust circular pipe 301 and the exhaust channel 305, and can effectively improve the response sensitivity of the exhaust valve.

[0051] Embodiment 3

[0052] In order to prevent the second exhaust hole 308 and the third exhaust hole 309 from being blocked by impurities such as dust in the air, based on the above embodiment, Figure 1-Figure 3 as well as Fig. 9 As shown, the present embodiment is provided with a jet anti-blocking mechanism 5. Specifically, the jet anti-blocking mechanism 5 includes a jet round tank 501 fixedly mounted on the sealing top plate 2. The upper end of the jet round tank 501 is connected with an exhaust pipe 502. The exhaust pipe 502 extends to the top of the exhaust circular pipe 301 and is fixedly connected with a nozzle assembly 503. A plurality of jet vertical holes 504 are evenly spaced at the lower end of the nozzle assembly 503. The nozzle assembly 503 is coaxially arranged with the exhaust circular pipe 301, and the number of the jet vertical holes 504 matches the number of the exhaust holes.

[0053] According to the above content, initially, the exhaust pipe 301 extends above the sealing top plate 2 . At this time, the second exhaust hole 308 and the third exhaust hole 309 are exposed, and the first exhaust hole 307 contacts the inner wall of the exhaust channel 305 .

[0054] At regular intervals (usually three days), the jet cylinder 501 will automatically exhaust air through the exhaust pipe 502, and then the gas will be ejected outward through the multiple jet vertical holes 504 on the nozzle assembly 503, thereby jet cleaning the second exhaust hole 308 and the third exhaust hole 309.

[0055] Moreover, the vertical jet holes 504 are all located on the side of the nozzle assembly 503, and the blowing direction is horizontal, which will not cause the exhaust pipe 301 to move downward.

[0056] This embodiment provides a jet anti-blocking mechanism 5 and utilizes the cooperation between the nozzle assembly 503 and the jet round tank 501 to regularly blow and clean the second exhaust hole 308 and the third exhaust hole 309 to prevent the exhaust holes from being blocked by dust and impurities, thereby ensuring the normal operation of the exhaust valve.

[0057] Embodiment 4

[0058] In order to improve the stability of the drain valve during operation, based on the above embodiments, Figure 1 , Figure 2 , Fig.10 as well as Fig.11 As shown, the present embodiment is provided with an auxiliary installation mechanism 6. Specifically, the auxiliary installation mechanism 6 comprises a fixed bracket 601 symmetrically arranged on the outside of the valve body housing 1. A mounting circular shaft is fixedly installed at the lower end of the fixed bracket 601. A movable protrusion 602 is rotatably connected to the mounting circular shaft. A mounting slide rail 603 is fixedly installed on the movable protrusion 602. Two arc clamps 604 are symmetrically installed on each mounting slide rail 603. A bidirectional screw rod 605 is movably installed inside the mounting slide rail 603. The two arc clamps 604 are respectively threadedly matched with the bidirectional screw rod 605. The side of the mounting slide rail 603 is movably installed. A threaded protrusion 606 is installed, and the threaded protrusion 606 is coaxially fixedly connected with the bidirectional screw rod 605. When the exhaust valve is installed, the two arc clamps 604 will be located on both sides of the water supply pipe respectively. When the staff twists the threaded protrusion 606, the two arc clamps 604 will be close to each other. A sliding limiter 607 is movably installed on the side of the movable protrusion 602, and a limiting groove 608 is provided on the side of the installation circular shaft. The outer surface shape of the sliding limiter 607 matches the shape of the limiting groove 608. When the sliding limiter 607 is located inside the limiting groove 608, the movable protrusion 602 is in a limited state.

[0059] According to the above content, when installing the valve body shell 1, first connect the lower end of the valve body shell 1 to the water pipeline. At this time, the two sets of arc clamps 604 will be located on both sides of the water pipeline respectively. Next, the staff will screw the threaded protrusion 606 to rotate the bidirectional screw rod 605. When the bidirectional screw rod 605 rotates, the two arc clamps 604 will be close to each other, thereby clamping the water pipeline, which can effectively improve the stability of the valve body shell 1 during operation.

[0060] If the water pipes on both sides of the installation site are in a downward bending state (because the drain valve generally needs to be installed at the highest point of the water supply system), the staff will first pull out the sliding limit piece 607, and then rotate the movable protrusion 602 to make the arc clamp 604 and the water pipe in a vertical state, and then push the sliding limit piece 607 into the interior of the limiting groove 608 to fix the movable protrusion 602, and finally twist the threaded protrusion 606 to clamp and limit the water pipe.

[0061] This embodiment provides an auxiliary installation mechanism 6, and utilizes the mutual cooperation between the arc clamp 604 and the threaded protrusion 606 to automatically clamp and limit the water pipes on both sides during the installation of the valve body, which can greatly improve the stability of the drain valve during operation; moreover, this embodiment provides an auxiliary installation mechanism 6, and utilizes the mutual cooperation between the movable protrusion 602 and the sliding limiter 607 to help the staff flexibly adjust the angle of the arc clamp 604, even if the water pipes on both sides of the installation site are bent downward, they can still be firmly clamped, and the application range is wide.

[0062] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
