Description

Technical Field

[0001] The present invention relates to the technical field of water valves, and specifically to an anti-long-flow self-closing automatic control water valve. Background Art

[0002] A water valve is a device used to control the flow of water. Its core function is to adjust and control the size of the water flow in the pipeline, thereby facilitating the maintenance and management of the pipeline. Through the opening, closing or adjustment of its internal structure, the water valve can accurately control the flow state of the water flow in the pipeline, including flow rate, flow velocity and flow direction, etc.

[0003] The patent application with the Chinese patent application number CN201110061739.X discloses an anti-long-flow self-closing automatic control water valve. Although this application can automatically identify the long-flow water phenomenon caused by forgetting to close the valve, faucet damage or pipeline leakage, and automatically close the valve and send an alarm message, when this application is put into use, due to the impact of the internal water flow on the valve plate when the water valve is closed, the pipeline is prone to explosion, and this problem needs to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide an anti-long-flow self-closing automatic control water valve to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: An anti-long-flow self-closing automatic control water valve includes a water pipe, and also includes a control component. The top right of the water pipe is fixedly connected with a storage shell, the top of the storage shell is fixedly connected with a protective shell, and a detection module is arranged at the left side of the inner bottom of the water pipe.

[0006] Among them, the control component includes: An electric telescopic rod is fixedly connected to the middle of the top of the protective shell. The electric telescopic rod has an output shaft, and a sealing valve plate is fixedly connected to the output shaft of the electric telescopic rod. A valve slot is fixedly connected to the right side of the water pipe below the storage shell, and the sealing valve plate can be inserted into the valve slot to seal the valve slot.

[0007] According to the above technical solution, it further includes a sliding component, and the sliding component is composed of a guiding sliding frame, a guiding sliding block, a limiting sliding block and a moving connecting block.

[0008] The guiding sliding frame is fixedly connected to the inner top of the water pipe, the guiding sliding block is slidably connected to the inside of the guiding sliding frame, the limiting sliding blocks are fixedly connected to the front and back of the guiding sliding block, and the moving connecting block is fixedly connected to the bottom of the limiting sliding block. The guiding sliding block can slide within the guiding sliding frame.

[0009] According to the above technical solution, it further includes a buffer assembly, and the buffer assembly is composed of a movable sliding frame, a first rotating connection block, a rubber circular convex plate, and a second rotating connection block.

[0010] The movable sliding frame is fixedly connected to the bottom of the movable connection block. The first rotating connection block is rotatably connected to the middle part inside the movable sliding frame. The rubber circular convex plate is fixedly connected to the side of the first rotating connection block away from the movable sliding frame. The second rotating connection block is fixedly connected to the bottom of the rubber circular convex plate, and the first rotating connection block can rotate inside the movable sliding frame.

[0011] According to the above technical solution, the inside of the storage shell and the protective shell is connected and communicated. The telescopic end of the electric telescopic rod penetrates through the top of the protective shell and extends into the storage shell and is fixedly connected to the top of the sealing valve plate. When the electric telescopic rod works, it can control the lifting of the sealing valve plate.

[0012] According to the above technical solution, sliding grooves corresponding to the limit sliding blocks are provided on both the front and back of the guiding sliding frame. The guiding sliding block is slidably connected to the guiding sliding frame through the limit sliding block, and the guiding sliding block slides inside the guiding sliding frame through the limit sliding block.

[0013] According to the above technical solution, the second rotating connection block is rotatably connected to the middle part inside the active frame, and the second rotating connection block can rotate in the middle of the active frame as the sealing valve plate and the active frame descend.

[0014] According to the above technical solution, the number of the guiding sliding frame, the guiding sliding block, the limit sliding block, the movable connection block, the movable sliding frame, the first rotating connection block, the rubber circular convex plate, and the second rotating connection block is two. The two guiding sliding frames, guiding sliding blocks, limit sliding blocks, movable connection blocks, movable sliding frames, first rotating connection blocks, rubber circular convex plates, and second rotating connection blocks are symmetrically distributed on both sides of the sealing valve plate, and can control the water flow on both sides of the sealing valve plate.

[0015] According to the above technical solution, the detection module is composed of a flow monitor, a timer, and a PLC controller. The flow monitor can monitor the water flow velocity in the water pipe in real time. The timer can time the continuous flowing time of the water flow. The PLC controller controls the electric telescopic rod in a linkage manner according to the flow and time parameters collected by the two. When the flow monitor detects that the continuous flowing time t of the fluid is greater than t0, the PLC controller outputs a control signal to make the electric telescopic rod axially extend at a rate of v = kt until the flowing time t is less than t0.

[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. By setting the rotating connecting block 1 and the rubber convex plate to incline slowly inside the water pipe, the water flow channel can be gradually narrowed, the flow velocity can be gently decreased, the sudden change of kinetic energy into pressure energy can be avoided, the impact force when the sealing valve plate closes can be decreased, the valve flap and the sealing ring can be prevented from cracking due to high-frequency vibration fatigue, and the risk of pipe burst can be significantly reduced. 2. By setting the detection module, the water flow inside the water pipe can be detected in a linked manner. When the detection module detects that the water flow time inside the water pipe increases, it can judge whether the faucet is forgotten to be turned off. And as time goes by, it can control the telescopic head of the electric telescopic rod to gradually move downwards, reducing the total amount of water flow passing through the sealing valve plate inside the water pipe. When the time set by the detection module arrives, at this time, the electric telescopic rod controls the sealing valve plate to descend into the valve slot, and the valve slot can be sealed. 3. When the rotating connecting block 1 and the rubber convex plate are inclined inside the water pipe, the water flow passes through the surface of the rubber convex plate, and a hydraulic jump phenomenon is formed on the other side. The hydraulic jump phenomenon dissipates the kinetic energy of the high-speed flow through turbulent mixing and potential energy conversion, reduces the inertial impact force of the water flow, reduces the peak value of the water hammer pressure. At the same time, the local pressure in the hydraulic jump area rises above the saturated vapor pressure, inhibiting the formation and collapse of cavitation bubbles, and can provide cavitation protection for the sealing valve plate.

Detailed implementation mode

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as a limitation to the present invention.

[0021] Example 1, please refer to Figures 1-3 , the present invention provides a technical solution: an anti-long-flow self-shutting-off automatic control water valve, including a water pipe 1, and further including a control component 4. The top of the right side of the water pipe 1 is fixedly connected with a storage shell 2, the top of the storage shell 2 is fixedly connected with a protective shell 3, and a detection module 7 is arranged on the left side of the inner bottom of the water pipe 1.

[0022] Among them, the control component 4 includes: An electric telescopic rod 401, the electric telescopic rod 401 is fixedly connected to the middle of the top of the protective shell 3. The electric telescopic rod 401 has an output shaft, and the output shaft of the electric telescopic rod 401 is fixedly connected with a sealing valve plate 402. A valve groove 404 is fixedly connected to the lower part of the storage shell 2 on the right side of the water pipe 1. The sealing valve plate 402 can be inserted into the valve groove 404 to seal the valve groove 404.

[0023] The storage shell 2 and the protective shell 3 are connected and communicated. The telescopic end of the electric telescopic rod 401 penetrates through the top of the protective shell 3 and extends into the storage shell 2 to be fixedly connected with the top of the sealing valve plate 402. When the electric telescopic rod 401 works, it can control the sealing valve plate 402 to rise and fall.

[0024] The detection module 7 is composed of a flow monitor, a timer, and a PLC controller. The flow monitor can monitor the water flow velocity in the water pipe 1 in real time. The timer can measure the continuous flowing time of the water. The PLC controller controls the electric telescopic rod 401 in a linkage manner according to the flow rate and time parameters collected by the two. When the flow monitor detects that the continuous flowing time t of the fluid is greater than the preset threshold value t0, the PLC controller outputs a control signal to make the electric telescopic rod 401 axially extend at a rate of v = kt (k is the proportionality coefficient) until the flowing time t is less than t0.

[0025] By setting up the detection module, the water flow in the water pipe 1 can be detected in a linkage manner. It can judge whether the faucet is forgotten to be turned off when the detection module detects that the water flow time in the water pipe 1 increases. And as time increases, it can control the telescopic head of the electric telescopic rod 401 to gradually move down, reducing the total amount of water flow in the water pipe 1 passing through the sealing valve plate 402. After the time set by the detection module arrives, at this time, the electric telescopic rod 401 controls the sealing valve plate 402 to descend into the valve groove 404, and can seal the valve groove 404.

[0026] Example two, please refer to Figures 1-7 , on the basis of Example one, the present invention provides a technical solution: it further includes a sliding component 5, and the sliding component 5 is composed of a guiding sliding frame 501, a guiding sliding block 502, a limiting sliding block 503, and a moving connection block 504.

[0027] The guiding sliding frame 501 is fixedly connected to the inner top of the water pipe 1. The guiding sliding block 502 is slidably connected to the inside of the guiding sliding frame 501. The limiting sliding blocks 503 are fixedly connected to the front and back of the guiding sliding block 502. The moving connection block 504 is fixedly connected to the bottom of the limiting sliding block 503. The guiding sliding block 502 can slide within the guiding sliding frame 501.

[0028] It further includes a buffer component 6, and the buffer component 6 is composed of a moving sliding frame 601, a rotating connection block one 602, a rubber circular convex plate 603, and a rotating connection block two 604.

[0029] The moving sliding frame 601 is fixedly connected to the bottom of the moving connection block 504. The rotating connection block one 602 is rotatably connected to the middle inside the moving sliding frame 601. The rubber circular convex plate 603 is fixedly connected to the side of the rotating connection block one 602 away from the moving sliding frame 601. The rotating connection block two 604 is fixedly connected to the bottom of the rubber circular convex plate 603. The rotating connection block one 602 can rotate within the moving sliding frame 601.

[0030] Sliding grooves corresponding to the limit sliding blocks 503 are provided on both the front and back of the guiding sliding frame 501. The guiding sliding block 502 is slidably connected to the guiding sliding frame 501 through the limit sliding block 503, and the guiding sliding block 502 slides within the guiding sliding frame 501 through the limit sliding block 503.

[0031] The second rotating connection block 604 is rotatably connected to the middle part inside the active frame 403. The second rotating connection block 604 can rotate in the middle of the active frame 403 as the sealing valve plate 402 and the active frame 403 descend.

[0032] The numbers of the guiding sliding frame 501, the guiding sliding block 502, the limit sliding block 503, the moving connection block 504, the moving sliding frame 601, the first rotating connection block 602, the rubber round convex plate 603 and the second rotating connection block 604 are all two. The two guiding sliding frames 501, guiding sliding blocks 502, limit sliding blocks 503, moving connection blocks 504, moving sliding frames 601, first rotating connection blocks 602, rubber round convex plates 603 and second rotating connection blocks 604 are symmetrically distributed on both sides of the sealing valve plate 402, and can control the water flow on both sides of the sealing valve plate 402.

[0033] When the first rotating connection block 602 and the rubber round convex plate 603 are arranged obliquely inside the water pipe 1, the water flow passes through the surface of the rubber round convex plate 603, and a hydraulic jump phenomenon is formed on the other side. The hydraulic jump phenomenon dissipates the kinetic energy of the high-speed flow through turbulent mixing and potential energy conversion, reduces the inertial impact force of the water flow, reduces the peak value of the water hammer pressure. At the same time, the local pressure in the hydraulic jump area rises above the saturated vapor pressure, inhibiting the formation and collapse of cavitation bubbles, and can provide cavitation protection for the sealing valve plate 402.

[0034] By arranging the first rotating connection block 602 and the rubber round convex plate 603 to incline slowly inside the water pipe 1, the water flow channel can be gradually narrowed, the flow velocity can be gently decreased, and the sudden change of kinetic energy into pressure energy can be avoided. The impact force when the sealing valve plate 402 is closed can be decreased, and the valve flap and the sealing ring can be prevented from cracking due to high-frequency vibration fatigue, significantly reducing the risk of pipe explosion.

[0035] After the detection module detects that the water flow in the water pipe 1 has been flowing for a long time and has not been shut off, the electric telescopic rod 401 works, causing the electric telescopic rod 401 to drive the sealing valve plate 402 to descend, so that the sealing valve plate 402 and the active frame 403 descend synchronously. When the active frame 403 descends, it pulls the rotating connection block two 604. At this time, the rotating connection block two 604 pulls the rubber round convex plate 603 and the rotating connection block one 602 downward, causing the rotating connection block one 602 to rotate within the moving sliding frame 601. At the same time, the guiding sliding block 502 at the top of the moving sliding frame 601 slides within the guiding sliding frame 501. During the sliding process of the guiding sliding block 502, the rotation angles of the rotating connection block one 602 and the rubber round convex plate 603 within the moving sliding frame 601 increase from small to large. At the same time, when the water flow in the water pipe 1 is flowing, it can reduce the volume of the water flow within the water pipe 1, and at the same time slowly reduce the area where the water flow can impact the sealing valve plate 402, reducing the damage to the sealing valve plate 402 caused by the water hammer effect impact.

[0036] When the sealing valve plate 402 is inserted into the valve groove 404 to close the inside of the water pipe 1, at this time, the rotating connection block one 602 and the rubber round convex plate 603 are in an inclined state, which can buffer the water flow when the water flow contacts the rubber round convex plate 603. The buffered water flow contacts the surface of the sealing valve plate 402 and rises, which can wash the surface of the sealing valve plate 402.

[0037] When the inclination angles of the rotating connection block one 602 and the rubber round convex plate 603 with the moving sliding frame 601 are 45 degrees, the water flow passes through the left side of the rubber round convex plate 603 and moves to the right side. At this time, since the rubber round convex plate 603 is in a convex state, it can cause the passing water flow to form a hydraulic jump phenomenon. After the hydraulic jump phenomenon is formed, the water flow velocity increases, which can wash the inner wall of the valve groove 404 and prevent the accumulation of water scale on the inner wall of the valve groove 404.
