Description

Technical Field

[0001] This utility model relates to the technical field of one-way valve devices, specifically a one-way valve with a filtering function. Background Technology

[0002] The working principle of a check valve is based on the directionality of fluid flow. When fluid enters from the inlet (P port), it overcomes the spring force and friction to open the valve disc, allowing the fluid to flow from the inlet to the outlet (A port). In the case of reverse flow, i.e., when there is no compressed air or fluid at the P port, the valve disc remains closed under the action of the spring force and the residual air force at the A port, preventing the fluid from flowing from the A port to the P port. Check valves are divided into two types: straight-through and right-angle. Straight-through check valves are usually installed on pipelines with threaded connections, while right-angle check valves have three forms: threaded connection, plate connection, and flange connection. In addition, check valves are also divided into two types: swing valves and lift valves. The former opens and closes by rotating around the center of gravity, while the latter moves along the axis.

[0003] Current check valves, when guiding liquids in a one-way manner, use a filter plate to filter the liquid before it enters the check valve to protect the internal components and prevent impurities from entering. However, as the liquid flow rate increases, the amount of impurities filtered also increases. Impurities accumulate and adhere to one end of the filter plate, clogging the filter holes and reducing their patency. This, in turn, reduces the overall flow efficiency of the device. Therefore, a check valve with a filtration function is provided. Utility Model Content

[0004] The purpose of this invention is to provide a one-way valve with a filtration function to solve the problem mentioned in the background art of impurities accumulating and adhering to one end of the filter plate in the guided liquid, causing blockage of the filter plate pores and thus reducing the overall flow efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a one-way valve with a filtering function, comprising a one-way valve body, one end of which is fixed with a first guide tube by bolts, the inner wall of which is fixed with a filter plate by bolts, and one side of which is fixed with a second guide tube by bolts; a cleaning mechanism, which is disposed at one end of the one-way valve body and extends into the interior of the first and second guide tubes, the cleaning mechanism being used to clean impurities adhering to one end of the filter plate, thereby ensuring the flowability of the filter holes of the filter plate, the cleaning mechanism including a rotating rod connected to the interior of the filter plate by bearings, the rotating rod extending to both ends of the filter plate, one end of the rotating rod near the one-way valve body being fixed with an impeller by bolts, and the other end of the rotating rod away from the impeller being fixed with a cleaning plate by bolts.

[0006] Preferably, the cleaning plate is provided with a plurality of evenly distributed flexible brushes at one end near the filter plate, and the flexible brushes are in contact with one end of the filter plate.

[0007] Preferably, a first valve body is slidably sleeved inside the one-way valve body. The end of the first valve body near the first guide pipe is frustum-shaped, and the end of the first valve body away from the first guide pipe is fixed with a moving rod by bolts. The moving rod extends to the outside of the one-way valve body.

[0008] Preferably, a spring is fixedly connected to the end of the first valve body away from the first guide tube, the spring is sleeved on the outer wall of the moving rod, and the end of the spring away from the first valve body is fixedly connected to the inner wall of the one-way valve body.

The sliding rod is located on one side of the moving rod, and one end of the sliding rod is slidably sleeved with a rotating column. The rotating column extends into the interior of the second guide tube, and the rotating column is rotatably connected to the inner wall of the second guide tube through a bearing. One end of the rotating column is fixedly connected to a second valve body, and the second valve body is located in the inner cavity of the second guide tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up a cleaning mechanism, the liquid passing through the first guide pipe can be filtered through the filter plate, preventing impurities in the liquid from entering the interior of the one-way valve body. After the liquid comes into contact with the impeller, it drives the impeller to rotate. The rotation of the impeller drives the cleaning plate to rotate through mechanical transmission, thereby cleaning one end of the filter plate and ensuring the unobstructed flow of the filter plate pores. When the device stops guiding the flow, the first valve body moves back to its original position and drives the second valve body to rotate back to its original position through mechanical transmission, thereby further closing the interior of the second guide pipe and improving the one-way flow guidance of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The following is in conjunction with the appendix Figures 1-5 The present invention will be described in further detail below.

[0022] Please see Figures 1-5This utility model provides a one-way valve with a filtering function: A one-way valve body 1 is used for one-way liquid flow. A first guide pipe 2 is bolted to one end of the one-way valve body 1 for liquid flow. A filter plate 201 is bolted to the inner wall of the first guide pipe 2 for filtering the liquid and preventing impurities from entering the interior of the one-way valve body 1. A second guide pipe 3 is bolted to one side of the one-way valve body 1 for liquid flow. A cleaning mechanism 4 is located at one end of the one-way valve body 1 and extends into the interior of the first guide pipe 2 and the second guide pipe 3. The cleaning mechanism 4 is used to clean impurities adhering to one end of the filter plate 201, thereby ensuring filtration. To ensure the flowability of the filter holes in the filter plate 201, the cleaning mechanism 4 includes a rotating rod 401 connected to the inside of the filter plate 201 via bearings. The rotating rod 401 extends to both ends of the filter plate 201. An impeller 403 is bolted to the end of the rotating rod 401 near the one-way valve body 1, and a cleaning plate 402 is bolted to the end of the rotating rod 401 away from the impeller 403. Liquid enters the interior of the first guide pipe 2 and, after being filtered by the filter plate 201, enters the interior of the one-way valve body 1. The liquid passes through the impeller 403 and squeezes the impeller 403, thereby driving the impeller 403 to rotate. The rotation of the impeller 403 drives the rotating rod 401 to rotate, which in turn drives the cleaning plate 402 to rotate. The rotating cleaning plate 402 cleans one end of the filter plate 201, thereby ensuring the unobstructed flow of the filter holes in the filter plate 201.

[0023] Multiple evenly distributed flexible brushes are provided at one end of the cleaning plate 402 near the filter plate 201, and the flexible brushes are in contact with one end of the filter plate 201. This structure allows the cleaning plate 402 to rotate, driving the multiple flexible brushes to rotate and thus cleaning one end of the filter plate 201 without damaging it. A first valve body 101 is slidably sleeved inside the one-way valve body 1. The end of the first valve body 101 near the first guide pipe 2 is frustoconical, and the end of the first valve body 101 away from the first guide pipe 2 is fixed with a moving rod 102 by bolts. The moving rod 102 extends to the outside of the one-way valve body 1. Liquid flows through the first guide pipe 2 and interacts with the first valve body 101. One end of the platform contacts the other, thereby squeezing the first valve body 101 to move. The movement of the first valve body 101 connects the one-way valve body 1, the first guide tube 2, and the second guide tube 3, thereby guiding the liquid in the first guide tube 2 to the interior of the second guide tube 3. A spring 1011 is fixedly connected to the end of the first valve body 101 away from the first guide tube 2. The spring 1011 is sleeved on the outer wall of the moving rod 102, and the end of the spring 1011 away from the first valve body 101 is fixedly connected to the inner wall of the one-way valve body 1. The spring 1011 is used to maintain the initial position of the first valve body 101, and the spring 1011 is used to provide a horizontal moving reset force to the first valve body 101, thereby achieving the purpose of one-way flow guidance of the one-way valve body 1.

[0024] One end of the moving rod 102 is bolted to a connecting rod 404, and the other end of the connecting rod 404 is bolted to a sliding rod 405. The sliding rod 405 is located on one side of the moving rod 102. One end of the sliding rod 405 is slidably sleeved with a rotating column 406. The rotating column 406 penetrates into the interior of the second guide tube 3 and is rotatably connected to the inner wall of the second guide tube 3 via a bearing. One end of the rotating column 406 is fixedly connected to a second valve body 407, which is located inside the second guide tube 3. The horizontal movement of the moving rod 102 drives the connecting rod 404 to move, which in turn drives the sliding rod 405 to move. The sliding rod 405 then drives the rotating column 406 to rotate, which in turn drives the second valve body 407 to rotate. This opens the inner cavity of the second guide pipe 3 when the one-way valve body 1 is working, and seals the inner cavity of the second guide pipe 3 when the one-way valve body 1 stops guiding flow, further improving the one-way flow guiding effect of the device. One end of the sliding rod 405 is welded with... A movable column 4051 is located inside the rotating column 406. A ball bearing 4052 is mounted on the outer wall of the movable column 4051. An arc-shaped groove 4061 is formed on the inner wall of the rotating column 406, and the arc-shaped groove 4061 is slidably fitted with the ball bearing 4052. Horizontal movement of the sliding rod 405 can move the movable column 4051, which in turn moves the ball bearing 4052. The ball bearing 4052 moves along the inner wall of the arc-shaped groove 4061 and presses against it, thereby moving the arc-shaped groove 4061. 1. Rotation: The arc-shaped groove 4061 rotates, causing the rotating column 406 to rotate. The second valve body 407 has a guide hole 4071 inside, which penetrates the second valve body 407. The opening shape of the guide hole 4071 matches the inner wall of the second guide tube 3. When the second valve body 407 rotates, it drives the guide hole 4071 to rotate. When the guide hole 4071 rotates and is parallel to the inner cavity of the second guide tube 3, the inner cavity of the second guide tube 3 opens, and the liquid can be guided through the guide hole 4071.

[0025] Working principle: In use, the liquid to be guided is first introduced into the first guide pipe 2. The liquid is filtered by the filter plate 201, and the impurities are filtered to one end of the filter plate 201. The liquid passing through the filter plate 201 comes into contact with the impeller 403 and squeezes the impeller 403 to rotate. The rotation of the impeller 403 drives the rotating rod 401 to rotate. The rotation of the rotating rod 401 drives the cleaning plate 402 to rotate. The rotation of the cleaning plate 402 drives multiple evenly distributed flexible brushes to rotate, thereby cleaning one end of the filter plate 201, preventing the accumulation of impurities at one end of the filter plate 201, and ensuring the unobstructed flow of the filter holes of the filter plate 201.

[0026] Secondly, after the liquid enters the interior of the one-way valve body 1, the liquid squeezes one end of the first valve body 101, thereby pushing the first valve body 101 to move. The spring 1011 is forced to squeeze the first valve body 101, causing the moving rod 102 to move. The moving rod 102 causes the connecting rod 404 to move. The moving rod 404 causes the sliding rod 405 to move. The moving rod 405 causes the moving column 4051 to move. The moving column 4051 causes the ball 4052 to move. The ball 4052 moves on the inner wall of the arc-shaped groove 4061 and squeezes the inner wall of the arc-shaped groove 4061, thereby causing the arc-shaped groove 4061 to rotate. The rotation of the arc-shaped groove 4061 causes the rotating column 406 to rotate. The rotation of the rotating column 406 causes the second valve body to rotate. When 407 rotates, the second valve body 407 rotates, causing the guide hole 4071 to rotate. When the one-way valve body 1, the first guide pipe 2 and the second guide pipe 3 are connected, the guide hole 4071 rotates to a state parallel to the inner cavity of the second guide pipe 3. At this time, the liquid can be guided through the first guide pipe 2, the one-way valve body 1 and the second guide pipe 3. When the liquid stops being transported, the squeezing force at one end of the first valve body 101 disappears. At this time, the spring 1011 returns to its original state and drives the first valve body 101 and the second valve body 407 to reset and rotate through mechanical transmission. The second valve body 407 resets and rotates, and drives the guide hole 4071 to reset and rotate. At this time, the interior of the first guide pipe 2 and the second guide pipe 3 is closed, which further improves the one-way flow guidance of the device.

[0027] Finally, the liquid passing through the first guide pipe 2 can be filtered by the filter plate 201 to prevent impurities in the liquid from entering the interior of the one-way valve body 1. After the liquid comes into contact with the impeller 403, it drives the impeller 403 to rotate. The rotation of the impeller 403 drives the cleaning plate 402 to rotate through mechanical transmission, thereby cleaning one end of the filter plate 201, thus ensuring the unobstructed flow of the filter holes of the filter plate 201. When the device stops guiding the flow, the first valve body 101 resets and moves, and drives the second valve body 407 to reset and rotate through mechanical transmission, thereby further closing the interior of the second guide pipe 3 and improving the one-way flow guidance of the device.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
