Technical Field

[0001] The invention relates to the technical field of flow measurement and control valves, and in particular to an LWP angle flow measurement and control valve with an inner wall anti-residue function. Background Art

[0002] The LWP angle flow measurement and control valve is equipped with a high-precision flow sensor inside. When working, it can measure the fluid flow through the pipeline in real time and accurately. Not only that, the LWP angle flow measurement and control valve also has the functions of automatic flow control and pressure balance adjustment, which can promptly detect abnormal flow and pressure in the system to ensure the normal operation of the system. After the LWP angle flow measurement and control valve has been working for a long time, scale will remain on the inner wall, which will affect the measurement of the sensor and increase the energy consumption of the system. In order to overcome the above defects, the prior art (Chinese patent application with application number 202411035170.3 and application date 2024-07-31) LWP flow measurement and control device, when working, sets an anti-residue structure on the inner wall of the water inlet pipe to prevent impurities from sticking to the inner wall of the casing, which is convenient for subsequent cleaning by the staff and also improves the overall working efficiency of the device.

[0003] After working for a long time, scale nodules will be deposited on the inner wall of the water outlet pipe, which will also affect the normal use of the valve body. The device in the above application does not have a structure for auxiliary cleaning of the water outlet pipe during use, and is not conducive to the long-term use of the device. It will not only affect the operation of the valve body system, but also affect the service life of the valve body. Therefore, we propose an LWP angle flow measurement and control valve with anti-residue on the inner wall to solve the above-mentioned problems. Summary of the invention

[0004] The purpose of the present invention is to provide an LWP angle flow measurement and control valve with anti-residue inner wall, so as to solve the problem proposed in the above background technology that during use, there is no structure for auxiliary cleaning of the water outlet pipe, which is not conducive to the long-term use of the device, which not only affects the operation of the valve body system, but also affects the service life of the valve body.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an LWP angle flow measurement and control valve with anti-residue on the inner wall, comprising a flow actuator, wherein the lower surface of the flow actuator is connected to a flow controller, and the right side surface of the flow controller is connected to a water inlet pipe, and the lower side surface of the flow controller is connected to a water outlet pipe, and the left side of the water outlet pipe is connected to an intelligent meter; an inner plate is connected to the inner wall of the water inlet pipe, and a connecting shaft is arranged inside the inner plate, and a first cleaning component is arranged inside the water inlet pipe, the first cleaning component comprises a cleaning plate arranged inside the water inlet pipe, and the cleaning plate reciprocates inside the water inlet pipe when working; a rotating shaft is arranged inside the water outlet pipe, and a second cleaning component is arranged inside the water outlet pipe, the second cleaning component comprises a cleaning plate arranged inside the water outlet pipe, and the cleaning plate reciprocates inside the water outlet pipe when working.

[0006] Preferably, a long rod is fixedly connected to the surface of the connecting shaft, and a brush plate is fixedly connected to the end of the long rod, and a water wheel is fixedly connected to the end of the connecting shaft and the end of the rotating shaft, and a filter is fixedly connected to the inner wall of the water inlet pipe.

[0007] The arrangement of the above structure can prevent large particles of impurities from entering the interior of the water inlet pipe through the operation of the filter, thereby ensuring the working efficiency of the water inlet pipe.

[0008] Preferably, the first cleaning component also includes a cam fixedly connected to the surface of the connecting shaft, a limiting rod is fixedly connected to the inner wall of the water inlet pipe, and the limiting rod is an inverted "U" shape when viewed from the front, and a slider is slidably provided on the surface of the limiting rod.

[0009] Preferably, the lower surface of the slider is concave, and a connecting rod is rotatably provided inside the slider, and a force-bearing plate is rotatably provided on the other side of the connecting rod, and the upper surface of the slider is fixedly connected to the inner wall of the cleaning plate.

[0010] The arrangement of the above structure enables the connecting shaft to rotate under the action of water flow and water wheel, and then the connecting shaft drives the cam to rotate synchronously. At this time, the cam will intermittently push the force plate, that is, the force plate intermittently works on the slider through the connecting rod. At this time, the slider drives the cleaning plate to make reciprocating linear motion in the horizontal direction under the action of the connecting rod, connecting spring and limit rod. At this time, the cleaning plate wipes the inner wall of the water inlet pipe to prevent scale from precipitating and forming nodules, thereby ensuring the working efficiency of the water inlet pipe.

[0011] Preferably, the connecting rods are symmetrically distributed on the left and right sides of the force-bearing plate, and the lower surface of the force-bearing plate is in contact with the surface of the cam.

[0012] Preferably, a connection spring having an elastic reset function is fixedly connected to the surface of the sliding block, and the other side of the connection spring is fixedly connected to the inner wall of the limiting rod.

[0013] The above-mentioned structural arrangement enables the cleaning plates to be distributed on both sides of the force-bearing plate, thereby optimizing the cleaning effect.

[0014] Preferably, the second cleaning assembly further comprises a circular plate fixedly connected to the surface of the rotating shaft, and active blocks are fixedly connected to the lower surface of the circular plate, and the active blocks are distributed at equal angles on the lower surface of the circular plate.

[0015] The arrangement of the above structure enables the rotating shaft to rotate under the action of water flow and the water wheel. When the rotating shaft rotates, it will drive the circular plate and the active block to rotate synchronously.

[0016] Preferably, the second cleaning assembly further comprises a guide rod fixedly connected to the inner wall of the water outlet pipe, and the guide rod is an inverted "L" structure when viewed from the left, and the guide rods are symmetrically distributed on the inner wall of the water outlet pipe.

[0017] Preferably, a movable plate is slidably provided on the surface of the guide rod, and the end of the movable plate is fixedly connected to the cleaning plate, and a passive block is fixedly connected to the upper surface of the movable plate.

[0018] Preferably, the passive block and the active block are both hemispherical, a return spring having an elastic return function is fixedly connected to the upper surface of the movable plate, and the other side of the return spring is fixedly connected to the inner wall of the guide rod.

[0019] The arrangement of the above structure causes the active block to intermittently contact the passive block. At this time, the movable plate performs reciprocating linear motion in the vertical direction under the action of the active block, the passive block, the guide rod and the reset spring. At this time, the movable plate drives the cleaning plate to move synchronously, and finally the cleaning plate cleans the impurities on the inner wall of the water outlet pipe to prevent scale from settling, thereby ensuring the working efficiency of the water outlet pipe. At the same time, cleaning structures are provided on the inner walls of the water inlet pipe and the water outlet pipe, so that no dirt will be generated on the inner walls of the water inlet pipe and the water outlet pipe, thereby ensuring the overall working efficiency of the device.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: a new type of structural design is adopted, and the inner wall of the water inlet pipe can be cleaned by setting a connecting shaft and a brush plate. At the same time, a first cleaning component is also provided, so that the cleaning plate can also wipe the inner wall of the water inlet pipe, so that scale does not precipitate and form nodules, which is convenient for the use of the water inlet pipe. In addition, a second cleaning component is provided on the inner wall of the water outlet pipe, so that the cleaning plate can make a reciprocating linear motion on the inner wall of the water outlet pipe, and the cleaning plate can clean the inner wall of the water outlet pipe, so that impurities and scale do not form nodules on the inner wall of the water outlet pipe, thereby ensuring the working efficiency of the water outlet pipe. Furthermore, cleaning structures are provided on the inner walls of the water inlet pipe and the water outlet pipe, so that no dirt is generated on the inner walls of the water inlet pipe and the water outlet pipe, thereby ensuring the overall working efficiency of the device. The specific contents are as follows: (1) When the water inlet pipe is working, the water wheel of the LWP angle flow measurement and control valve drives the connecting shaft to rotate. When the connecting shaft rotates, it drives the brush plate to clean the inner wall of the water inlet pipe. At the same time, the cleaning plate makes reciprocating linear motion on the inner wall of the water inlet pipe. At this time, the cleaning plate can also clean the inner wall of the water inlet pipe, thereby optimizing the anti-residue effect and preventing scale nodules. When the filter is working, it can prevent large particles of impurities from entering the interior of the water inlet pipe, thereby ensuring the working efficiency of the water inlet pipe.

[0021] Furthermore, when the connecting shaft rotates, it drives the cam to rotate synchronously. At this time, the cam will intermittently push the force plate, and then the force plate drives the slider to move through the connecting pipe. At this time, the slider makes reciprocating linear motion in the horizontal direction under the action of the force plate, the limit rod and the connecting spring, and then the slider drives the cleaning plate to wipe the inner wall of the water inlet pipe. At the same time, the cleaning plates are symmetrically distributed on both sides of the force plate, which optimizes the cleaning effect.

[0022] Furthermore, when working, the flow actuator collects data, and the collected data is processed by the intelligent meter, displayed on the front end, and integrated by the staff, which makes it easier for the staff to detect the flow. In addition, the flow size can be controlled by the flow controller, which makes it easier for the staff to control the flow.

[0023] (2) When high-speed water flows into the outlet pipe, the rotating shaft of the LWP angle flow measurement and control valve rotates under the action of the water wheel. When the rotating shaft rotates, it drives the circular plate and the active block to rotate synchronously, and then the active block will intermittently contact the passive block. At this time, the movable plate makes reciprocating linear motion in the vertical direction under the action of the active block, the passive block, the guide rod and the reset spring. At this time, the movable plate drives the cleaning plate to move synchronously. Finally, the cleaning plate cleans the impurities on the inner wall of the outlet pipe, prevents scale from settling, and ensures the working efficiency of the outlet pipe.

[0024] (3) The LWP angle flow measurement and control valve with anti-residue inner wall is provided with a cleaning structure on the inner wall of the water inlet pipe and the water outlet pipe, so that no dirt will be generated on the inner wall of the water inlet pipe and the water outlet pipe, thereby ensuring the overall working efficiency of the device.

DETAILED DESCRIPTION

[0027] 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.

[0028] See also Figure 1-Figure 10 The present invention provides the following technical solution: an LWP angle flow measurement and control valve with anti-residue inner wall.

[0029] Embodiment 1: By setting the connecting shaft 6 and the brush plate 10, impurities on the inner wall of the water inlet pipe 2 can be cleaned. Figure 1-Figure 3 As shown, it includes a flow actuator 1, the lower surface of the flow actuator 1 is bolted to a flow controller 4, and the right side surface of the flow controller 4 is bolted to an inlet pipe 2, and the lower side surface of the flow controller 4 is bolted to an outlet pipe 3, and the left side of the outlet pipe 3 is fixedly connected to an intelligent meter 24, the surface of the connecting shaft 6 is fixedly connected to a long rod 26, and the end of the long rod 26 is fixedly connected to a brush plate 10, and a filter screen 25 is fixedly connected to the inner wall of the inlet pipe 2.

[0030] When the water inlet pipe 2 is working, the high-speed water flow will impact the water wheel 8. At this time, the connecting shaft 6 rotates inside the inner plate 5, and then the connecting shaft 6 drives the brush plate 10 to rotate synchronously. At this time, the brush plate 10 can clean the impurities on the inner wall of the water inlet pipe 2, and prevent the impurities and scale from settling, thereby avoiding the corrosion of the water inlet pipe 2, which not only ensures the normal operation of the water inlet pipe 2, but also extends the service life of the water inlet pipe 2. At the same time, during the working process, the flow actuator 1 collects data. The collected data is processed by the intelligent meter 24, displayed on the front end, and integrated by the staff, which is convenient for the staff to detect the flow. In addition, the flow controller 4 can be used to control the flow size, which is convenient for the staff to control the flow.

[0031] Embodiment 2: Different from Embodiment 1, a first cleaning component is provided on the inner wall of the water inlet pipe 2, and the inner wall of the water inlet pipe 2 can be wiped by the cleaning plate 16, thereby optimizing the effect of descaling and preventing residue. Figure 4-Figure 6 As shown, an inner plate 5 is fixedly connected to the inner wall of the water inlet pipe 2, and a connecting shaft 6 is rotatably arranged inside the inner plate 5, and a first cleaning component is arranged inside the water inlet pipe 2, the first cleaning component includes a cleaning plate 16 slidably arranged inside the water inlet pipe 2, and when the cleaning plate 16 is working, it reciprocates inside the water inlet pipe 2, the first cleaning component also includes a cam 9 fixedly connected to the surface of the connecting shaft 6, a limiting rod 11 is fixedly connected to the inner wall of the water inlet pipe 2, and the front view of the limiting rod 11 is an inverted "U" shape, and a slider 12 is slidably arranged on the surface of the limiting rod 11.

[0032] The lower surface of the slider 12 is concave, and a connecting rod 14 is rotatably provided inside the slider 12, and a force plate 13 is rotatably provided on the other side of the connecting rod 14, and the upper surface of the slider 12 is fixedly connected to the inner wall of the cleaning plate 16, and the connecting rods 14 are symmetrically distributed on the left and right sides of the force plate 13, and the lower surface of the force plate 13 is in contact with the surface of the cam 9, and a connecting spring 15 which plays an elastic reset role is fixedly connected to the surface of the slider 12, and the other side of the connecting spring 15 is fixedly connected to the inner wall of the limit rod 11.

[0033] When the connecting shaft 6 rotates inside the inner plate 5, it will drive the cam 9 to rotate synchronously, and then the cam 9 will intermittently push the force-bearing plate 13. When the force-bearing plate 13 is pushed, the force-bearing plate 13 will push the slider 12 through the connecting rod 14, so that the slider 12 slides on the surface of the limit rod 11. At the same time, the slider 12 will squeeze the connecting spring 15. When the cam 9 continues to rotate until it stops pushing the force-bearing plate 13, the slider 12 loses the thrust of the connecting rod 14. At this time, the slider 12 moves back under the action of the connecting spring 15 and the limit rod 11, and then the force-bearing plate 13 is pushed back by the connecting rod 14, and finally the force-bearing plate 13 is pushed back. The force plate 13 returns to its original position and the above process is repeated. The slider 12 performs reciprocating linear motion in the horizontal direction, that is, the slider 12 drives the cleaning plate 16 to move synchronously. At this time, the cleaning plate 16 will wipe the inner wall of the water inlet pipe 2. At the same time, the cleaning plates 16 are symmetrically distributed on both sides of the force plate 13, thereby optimizing the cleaning effect. During the movement of the slider 12, the limit rod 11 also limits the moving distance of the slider 12 to prevent the slider 12 from falling, thereby ensuring stability. When the filter screen 25 is working, it can prevent large particles of impurities from entering the interior of the water inlet pipe 2, thereby ensuring the working efficiency of the water inlet pipe 2.

[0034] Embodiment 3: Different from Embodiment 2, a second cleaning assembly is provided on the inner wall of the water outlet pipe 3, so that the cleaning plate 22 can clean the inner wall of the water outlet pipe 3 without causing scale impurities to settle. Figure 7-10 As shown, a rotating shaft 7 is rotatably provided inside the water outlet pipe 3, and the ends of the rotating shaft 7 and the ends of the connecting shaft 6 are fixedly connected with a water wheel 8, and a second cleaning component is provided inside the water outlet pipe 3, the second cleaning component includes a cleaning plate 22 slidably provided inside the water outlet pipe 3, and when the cleaning plate 22 is working, it reciprocates inside the water outlet pipe 3, and the second cleaning component also includes a circular plate 17 fixedly connected to the surface of the rotating shaft 7, and the lower surface of the circular plate 17 is fixedly connected with an active block 18, and the active blocks 18 are distributed at equal angles on the lower surface of the circular plate 17.

[0035] The second cleaning component also includes a guide rod 19 fixedly connected to the inner wall of the water outlet pipe 3, and the left view of the guide rod 19 is an inverted "L" structure, and the guide rod 19 is symmetrically distributed on the inner wall of the water outlet pipe 3, and a movable plate 20 is slidably provided on the surface of the guide rod 19, and a cleaning plate 22 is fixedly connected to the end of the movable plate 20, and a passive block 21 is fixedly connected to the upper surface of the movable plate 20, and the passive block 21 and the active block 18 are both hemispherical, and a reset spring 23 that plays an elastic reset role is fixedly connected to the upper surface of the movable plate 20, and the other side of the reset spring 23 is fixedly connected to the inner wall of the guide rod 19.

[0036] When high-speed water flows into the outlet pipe 3, the rotating shaft 7 rotates under the action of the water wheel 8. When the rotating shaft 7 rotates, the circular plate 17 and the active block 18 are driven to rotate synchronously, and then the active block 18 will intermittently contact with the passive block 21 and push the passive block 21. When the passive block 21 is pushed by the active block 18, the passive block 21 drives the movable plate 20 to slide on the surface of the guide rod 19. At this time, the reset spring 23 is stretched, and when the circular plate 17 and the active block 18 continue to rotate and the active block 18 is not in contact with the passive block 21, the passive block 21 and the movable plate 20 are moved on the guide rod 19 and the reset spring 23. Under the action of the active block 18, the passive block 21, the guide rod 19 and the return spring 23, the movable plate 20 performs reciprocating linear motion in the vertical direction. At this time, the movable plate 20 drives the cleaning plate 22 to move synchronously, and finally the cleaning plate 22 cleans the impurities on the inner wall of the water outlet pipe 3, and does not allow scale to precipitate, thereby ensuring the working efficiency of the water outlet pipe 3. Furthermore, cleaning structures are provided on the inner walls of the water inlet pipe 2 and the water outlet pipe 3, so that no dirt will be generated on the inner walls of the water inlet pipe 2 and the water outlet pipe 3, thereby ensuring the overall working efficiency of the device.

[0037] The above is the working process of the entire device, and the contents not described in detail in this specification belong to the existing technology known to professional and technical personnel in this field.
