Description

Technical Field

[0001] The invention relates to the technical field of valves, and in particular to a self-cleaning ball valve which is easy to observe. Background Art

[0002] Valves are pipe accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure, and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc., and can also be divided into ball valves, butterfly valves, gate valves, etc. according to the type of their opening parts. Ball valves are a type of valve whose opening and closing parts are spherical and have a penetrating water passage through which water can flow. The valve can be opened or closed by rotating the opening and closing parts. Compared with traditional gate valves that require twisting the threaded rod to raise and lower the gate plate, the speed of opening and closing is faster and the opening and closing is more labor-saving.

[0003] Although the above-mentioned prior art can solve the corresponding technical problems, there are still certain defects: when the existing ball valve is installed in a household sewage pipe for use, since the sewage in the household sewage pipe often contains some impurities such as rice grains, after a period of use, it is easy to cause a large amount of impurities to adhere to the valve, affecting the normal opening and closing of the valve, and causing the valve to have insufficient water flow space and slow drainage speed. At the same time, it is difficult for users to determine the accumulation area of ​​impurities in the valve, making observation and cleaning very inconvenient. Summary of the invention

[0004] The object of the present invention is to provide a self-cleaning ball valve which is easy to observe and clean, has a slow clogging speed, and is easy to observe, in view of the defects and shortcomings of the prior art.

An impact block is provided in the middle section of the transverse rod, and a first spring is provided at the end of the inner wall of the sliding frame. When water flows through the filter plate, impurities are filtered by the filter plate, and the amount of impurity accumulation on the filter plate can be visually observed through the observation plate. At the same time, the water flow pushes the transverse rod to slide along the inner wall of the sliding frame and squeezes the first spring to generate elastic force. After the opening and closing member is closed, the transverse rod is pushed back by the elastic force of the first spring to move and hit the filter plate through the impact block to empty it. The impurities are attached, the impact block includes a rear frame fixedly connected to the middle section of the transverse rod, the outer wall of the rear frame is fixedly connected to two symmetrically distributed fin-shaped pieces, the inner wall of the rear frame is slidably provided with an impact head, one side of the impact head is provided with a contraction frame fixedly connected to the end of the inner wall of the rear frame, the inner wall of the contraction frame is fixedly provided with a second spring, the impact head includes a contact head and a pressure plate arranged on one side of the contact head and fixedly connected to the contraction frame, a hemispherical bump is provided on the surface of the pressure plate close to the contact head, an elastic frame is provided between the edge of the pressure plate and the edge of the contact head, and the contact head is away from the pressure plate. A hemispherical inner recess is provided at the side end portion, and a water pressure pipe integrally formed with the contact head is connected to the inner recess. Two symmetrically distributed discharge pipes penetrating the side wall of the contact head are provided at the end portion of the water pressure pipe. A slow discharge block is embedded in the inner wall of the discharge pipe. The slow discharge block includes a flow pipe embedded in the inner wall of the discharge pipe and an arc-shaped expansion groove arranged in the middle section of the inner wall of the flow pipe. A lightweight ball that can slide and close the flow pipe is provided at the top of the inner wall of the expansion groove. A protruding block is provided on the inner wall of the flow pipe below the lightweight ball, and a third spring is provided between the top surface of the protruding block and the bottom surface of the outer wall of the lightweight ball.

[0006] A further improvement is that flanges are provided at the ends of the water inlet pipe and the water outlet pipe.

[0007] A further improvement is that an automatic motor is provided at the top of the opening and closing member.

[0008] A further improvement is that a sealing ring made of silicone material is provided on the side wall of the connecting ring.

[0009] A further improvement is that: the transverse rod is symmetrically distributed on the middle section of the upper and lower positions of the impact block.

[0010] A further improvement is that the opening and closing member includes a rotating rod and a spherical valve core arranged at the bottom of the rotating rod, the rotating rod is provided with a water pipe that penetrates the end of the rotating rod and extends downward into the spherical valve core, the bottom end of the water pipe is connected to a surrounding pipe that is integrally formed with the spherical valve core, and the bottom end of the surrounding pipe is provided with an inner cavity cleaning pipe that penetrates the inner wall of the spherical valve core.

[0011] A further improvement is that the inner cavity cleaning tube includes an input tube connected to the bottom end of the surrounding tube and penetrating the inner wall of the spherical valve core, and two separation tubes symmetrically distributed at the ends of the input tube, the ends of the separation tubes are provided with inner guide tubes, and the ends of the inner guide tubes are provided with concentrated nozzles.

[0012] After adopting the above technical solution, the beneficial effects of the present invention are:

[0013] When the present invention is in use, the water inlet pipe is connected to the water inlet pipeline, and impurities are cleared and filtered through the filter plate to prevent impurities from entering the position of the opening and closing parts, which may cause a large amount of impurities to adhere to the opening and closing parts and make opening and closing difficult. At the same time, the filter plate is provided with a hemispherical protrusion so that impurities can be pushed to the edge of the filter plate by the water flow, so that the filter plate is not easy to be blocked. While the acrylic observation plate is used to ensure high pressure resistance, the blockage of the filter plate can be observed intuitively through the transparent acrylic. The observation is convenient and direct, and maintenance and cleaning can be carried out in time when blocked, without the need to check the entire drainage pipeline, so that the cause of the blockage is easy to find.

[0014] In the process of water flow passing through, the pressure of the water flow is output to the impact head and the transverse rod, so that the transverse rod slides along the sliding frame and squeezes the first spring, thereby generating elastic force. After the water delivery is completed, the water pressure disappears. At this time, the elastic force generated by the first spring can push the transverse rod back, so that the transverse rod moves and drives the impact head to directly impact the filter plate. Therefore, after each water delivery, the filter plate can be automatically cleaned by the impact of the impact head, thereby extending the maintenance cycle and preventing the valve from being blocked.

[0015] During use, high-pressure water can be introduced through the water pipe, and then pressed into the inner cavity cleaning tube through the surrounding tube, and then sprayed out through the inner cavity cleaning tube. The position of the high-pressure water flow is adjusted by the separation tube and the inner guide tube, and then under the action of the concentrated nozzle, it is sprayed into the inner cavity of the spherical valve core at high speed. At this time, if there are impurities attached to the inner cavity of the spherical valve core, they can be dispersed and flushed away by the sprayed high-pressure water flow. There is no need to disassemble for maintenance and cleaning, and the cleaning is more convenient and simple. BRIEF DESCRIPTION OF THE DRAWINGS

Water flows through the filter plate 54, impurities are filtered by the filter plate 54, and the amount of impurity accumulation on the filter plate 54 can be visually observed through the observation plate 53. At the same time, the water flow pushes the transverse rod 551 to slide along the inner wall of the sliding frame 553 and squeezes the first spring 555 to generate elastic force. After the opening and closing member 4 is closed, the elastic force of the first spring 555 pushes the transverse rod 551 back to move, and the transverse rod 551 is hit by the impact block 552 to clear the attached impurities. When in use, water is introduced into the filter plate 54. The pipe 2 is connected to the water inlet end of the external pipe, and the outlet pipe 3 is connected to the water outlet port of the external pipe. At this time, the valve body 1 can be installed between the external pipes. When in use, the opening and closing member 4 is rotated to make the rotating rod 42 of the opening and closing member 4 drive the spherical valve core 41 to rotate. After the inner cavity of the spherical valve core 41 is aligned with the water inlet pipe 2 and the water outlet pipe 3, the two can be connected, so that the water flow is output from the water inlet pipe 2 through the spherical valve core 41 to the water outlet pipe 3 and flows out from the water outlet pipe 3. After the water flow enters, it will first pass through the filter plate 54 set in the middle section of the water inlet pipe 2, and then the impurities carried therein will be retained on the filter plate 54, thereby effectively preventing the impurities from reaching the position of the spherical valve core 41, causing the spherical valve core 41 to be clogged and difficult to rotate due to the attachment of impurities. The filter plate 54 with hemispherical protrusions allows impurities to be pushed by the water flow to the edge of the filter plate 54, making the filter plate 54 not easily blocked. The observation plate 53 made of acrylic material is used to ensure high pressure resistance. The blockage of the filter plate 54 can be observed intuitively through the transparent acrylic. When the water flows, the pressure of the water flow is output to the impact head 23 of the impact block 552 and the transverse rod 551, so that the transverse rod 551 slides along the sliding frame 553 and squeezes the first spring 555, thereby generating elastic force. After the water delivery is completed, the water pressure disappears. At this time, the transverse rod 551 can be pushed back by the elastic force generated by the first spring 555, so that the transverse rod 551 moves and drives the impact head 23 to directly impact the filter plate 54, thereby each time the water is delivered. After the water flows through, the filter plate 54 can be automatically cleaned by the impact of the impact head 23, thereby extending the maintenance cycle and making the valve less likely to be blocked. In the process of water flowing inward, the water will impact the fin sheet 22, and then provide a greater water flow pressure through the fin sheet 22, so that the first spring 555 can accumulate a higher elastic force. At the same time, the water will also flow into the inner recess 234 provided on the contact head 233 of the impact head 23, and then the impact force of the water flow is further absorbed through the inner recess 234, and part of the water flow is introduced into the water pressure pipe 235 and discharged outward along the discharge pipe 236. At the same time, the water flow will first squeeze the lightweight ball 32 of the slow discharge block 237 during the discharge process, and cause the third spring 35 to deform, so that it moves and enters the expansion groove 33.Then, the water flow is discharged outward more slowly, and when the external water flow flows back, the elastic force of the third spring 35 is used to reclose the circulation pipe 31 to prevent backflow. At this time, the pressure applied by the water flow in the water pressure pipe 235 can be further expanded, and the water flow can generate a larger thrust, thereby making the first spring 555 and the contraction frame 24 arranged between the impact head 23 and the rear frame 21 can be further squeezed, thereby making the first spring 555 and the second spring 26 generate sufficient elastic force. After the water flow stops flowing, that is, the valve is closed, the high elastic force of the first spring 555 and the second spring 26 can be used to quickly push the contact head 233 of the impact head 23 to impact the filter plate 54, and at the moment of impact, the pressure plate 231 continues to move through inertia and the hemispherical protrusion provided thereon hits the contact head 233 again, generating a secondary impact, thereby making the attachments on the filter plate 54 can be shaken off under the action of high-intensity impact and secondary impact, so that the self-cleaning effect is enhanced. The effect is better, and the blockage caused by the adhesion of a large amount of impurities is further avoided, and the maintenance cycle is effectively extended. At the same time, during use, high-pressure water can be introduced through the water delivery pipe 43, and then the high-pressure water is pressed into the inner cavity cleaning pipe 45 through the surrounding pipe 44, and then the high-pressure water flow is diverted through the separation pipe 452 of the inner cavity cleaning pipe 45, and the position of the high-pressure water flow is adjusted through the inner guide pipe 453 so that it can be sprayed directly into the inner cavity of the spherical valve core 41. Then, under the action of the concentrated nozzle 454, the high-pressure water flow is sprayed into the inner cavity of the spherical valve core 41 at a high speed. At this time, if there are impurities attached to the inner cavity of the spherical valve core 41, they can be washed away by the sprayed high-pressure water flow, without disassembly for maintenance and cleaning, and cleaning is more convenient and simple. In addition, when the filter plate 54 is completely blocked, the entire observation cleaning structure 5 can be directly dismantled through the connecting ring 51 for replacement or cleaning, which is very convenient to use.

[0027] The ends of the water inlet pipe 2 and the water outlet pipe 3 are both provided with flanges 6, which facilitates the connection of the water inlet pipe 2 and the water outlet pipe 3 to external pipes;

[0028] The top of the opening and closing member 4 is provided with an automatic motor 7, which is conducive to making the rotation of the opening and closing member 4 more automated and the rotation opening and closing speed faster;

[0029] A sealing ring 52 made of silicone material is provided on the side wall of the connecting ring 51, which is beneficial to improving the sealing effect of the connecting ring 51 and preventing water leakage;

[0030] The transverse rod 551 is located in the middle of the upper and lower parts of the impact block 552 and has two elastic sheets 556 symmetrically distributed. This is beneficial for generating additional deformation elastic force through the elastic sheets 556 when the transverse rod 551 is impacted by water flow, thereby increasing the force of the impact block 552 being thrown out after the water flow impact stops, thereby making the self-cleaning effect stronger.

[0031] Working principle of the present invention: When the present invention is used, the water inlet pipe 2 is connected to the water inlet end of the external pipe, and the water outlet pipe 3 is connected to the water outlet port of the external pipe. At this time, the valve body 1 can be installed between the external pipes. When in use, the opening and closing member 4 is rotated to make the rotating rod 42 of the opening and closing member 4 drive the spherical valve core 41 to rotate. After the inner cavity of the spherical valve core 41 is aligned with the water inlet pipe 2 and the water outlet pipe 3, the two can be connected, so that the water flow is output from the water inlet pipe 2 through the spherical valve core 41 to the water outlet pipe 3 and flows out from the water outlet pipe 3. After the water flow enters, it will first pass through the filter plate 54 arranged in the middle section of the water inlet pipe 2, and then the impurities carried therein will be retained on the filter plate 54, thereby effectively preventing the impurities from reaching the position of the spherical valve core 41 and causing the spherical valve core 4 1 is clogged and difficult to rotate due to impurities. The filter plate 54 with hemispherical protrusions can push the impurities to the edge of the filter plate 54 by the water flow, making the filter plate 54 not easy to be clogged. The observation plate 53 made of acrylic material can ensure high pressure resistance. The clogging of the filter plate 54 can be observed intuitively through the transparent acrylic. When the water flows, the pressure of the water flow is output to the impact head 23 of the impact block 552 and the transverse rod 551, so that the transverse rod 551 slides along the sliding frame 553 and squeezes the first spring 555, thereby generating elastic force. After the water delivery is completed, the water pressure disappears. At this time, the elastic force generated by the first spring 555 can push the transverse rod 551 back, so that the transverse rod 551 moves And drive the impact head 23 to directly impact the filter plate 54, so that after each water delivery, the filter plate 54 can be automatically cleaned by the impact of the impact head 23, thereby extending the maintenance cycle and making the valve less likely to be blocked. In the process of water flowing inward, the water flow will impact the fin sheet 22, and then provide a greater water flow pressure through the fin sheet 22, so that the first spring 555 can accumulate a higher elastic force. At the same time, the water flow will also be poured into the inner recess 234 provided on the contact head 233 of the impact head 23, and then the impact force of the water flow is further absorbed through the inner recess 234, and part of the water flow is introduced into the water pressure pipe 235 and discharged outward along the discharge pipe 236. At the same time, the water flow will first squeeze the lightweight ball 32 of the slow discharge block 237 during the discharge process. This causes the third spring 35 to deform, causing it to move and enter the expansion groove 33, thereby causing the water flow to be discharged outward more slowly, and when the external water flow flows back, the elastic force of the third spring 35 can be used to reclose the circulation pipe 31 to prevent backflow. At this time, the pressure applied by the water flow in the water pressure pipe 235 can be further expanded, and the water flow can generate a greater thrust, thereby allowing the first spring 555 and the contraction frame 24 arranged between the impact head 23 and the rear frame 21 to be further squeezed, thereby allowing the first spring 555 and the second spring 26 to generate sufficient elastic force. After the water flow stops flowing, that is, the valve is closed, the high elastic force of the first spring 555 and the second spring 26 can be used to quickly push the contact head 233 of the impact head 23 to impact the filter plate 54.At the moment of impact, the pressure plate 231 continues to move due to inertia, and the hemispherical protrusions on it hit the contact head 233 again, generating a secondary impact, thereby allowing the attachments on the filter plate 54 to be shaken off under the action of high-intensity impact and secondary impact, thereby achieving a better self-cleaning effect, further avoiding blockage caused by a large amount of impurities adhering, and effectively extending the maintenance cycle. At the same time, during use, high-pressure water can be introduced through the water delivery pipe 43, and then the high-pressure water can be pressed into the inner cavity cleaning pipe 45 through the surrounding pipe 44, and then the high-pressure water can be separated through the separation pipe 452 of the inner cavity cleaning pipe 45. The high-pressure water flow is divided, and the position of the high-pressure water flow is adjusted through the inner guide tube 453 so that it can be sprayed directly toward the inner cavity of the spherical valve core 41. Then, under the action of the concentrated nozzle 454, the high-pressure water flow is sprayed into the inner cavity of the spherical valve core 41 at a high speed. At this time, if there are impurities attached to the inner cavity of the spherical valve core 41, they can be dispersed and washed away by the sprayed high-pressure water flow, without disassembly for maintenance and cleaning, and cleaning is more convenient and simple. In addition, when the filter plate 54 is completely blocked, the entire observation cleaning structure 5 can be directly dismantled through the connecting ring 51 for replacement or cleaning, which is very convenient to use.
