Description

Technical Field

[0001] The present invention relates to the technical field of control valves, and in particular to an anti-clogging remote control valve. Background Art

[0002] With the development of science and technology, scientific irrigation has become an indispensable part of modern agriculture. Different from traditional irrigation methods such as irrigation canals, modern agriculture mostly adopts drip irrigation and other methods. On the one hand, scientific irrigation ensures the needs of plant growth. On the other hand, it also effectively saves water resources and improves the utilization efficiency of water resources. In the process of scientific irrigation, its intelligence is greatly improved compared with traditional agriculture. With the use of various electrical equipment, remote automated fine irrigation process is realized. Among them, remote control valves play an important role in controlling water volume, realizing remote control and metered irrigation.

[0003] A remote-controlled valve is a valve that can be opened or closed by a remote signal. It is commonly used to control the flow of liquids or gases in industrial and residential facilities. The basic principle of existing remote-controlled valves is to install a sensor on the valve and connect the sensor to a remote control. When the remote control receives a remote signal, the remote sends a command to the sensor. The sensor decodes the signal and transmits it to an internal controller. The controller controls devices such as electromagnets or stepper motors based on the received signal, changing the valve core position and thus the flow of the medium.

[0004] However, in the process of modern agricultural irrigation, especially in the application of drip irrigation, the water flow in the water pipe is generally small and the water flow is slow, so the sediment in the water body will be deposited in the pipe, especially at the position of the control valve, where the sediment deposition phenomenon is more obvious, resulting in the blockage of the valve and the pipe, which brings inconvenience to agricultural irrigation. The existing method often avoids pipe blockage by filtering the water source or cleaning the pipe regularly. The whole process is time-consuming and labor-intensive. At the same time, the blockage of the pipe is deeply affected by the water source condition, and it is easy to cause untimely cleaning, which brings inconvenience to agricultural production. Therefore, a method that is simple to use and install, can automatically process the water flow at the remote control valve, thereby effectively avoiding the blockage of the remote control valve and bringing convenient anti-blocking remote control valve to agricultural production is an existing problem that needs to be solved urgently.

[0034] A fitting groove 26 is provided on the valve body 2, and the fitting groove 26 is as wide as the inner cavity of the valve body 2. A valve core device 24 is provided in the valve body 2, and a mounting frame 241 is provided in the valve core device 24. A servo motor 242 is installed on the mounting frame 241. The servo motor 242 is connected to a threaded rod 243, and the threaded rod 243 is connected to a valve core 244. The valve core 244 is installed in the fitting groove 26, and a space is provided between the valve core 244 and the fitting groove 26. The sealing mechanism 245 is provided with an installation groove 2453, the fitting groove 26 is recessed in the installation groove 2453, a sealing ring 2452 is placed around the installation groove 2453, a pressure plate 2451 is provided on the sealing ring 2452, the pressure plate 2451 is fastened to the installation groove 2453, and a sealing layer 2441 is bonded to the front and rear sides and the bottom surface of the valve core 244, and the sealing layer 2441 is a tendon layer.

[0035] A shell 1 is provided on the valve body 2, and the shell 1 consists of a top cover 11 and a bottom cover 12. The top cover 11 and the bottom cover 12 are detachably fixedly connected, and slots 14 matching the water inlet 21 and the water outlet 22 are provided on both sides of the top cover 11 and the bottom cover 12. A power cord interface 15 is provided on the top cover 11, and an installation mark 16 is provided on the top cover 11. The direction of the installation mark 16 is from the water inlet 21 to the water outlet 22.

[0036] A control box 25 is provided in the valve body 2 , in which a single chip microcomputer 251 and a signal transmission module 252 are provided. The signal transmission module 252 is connected to an external terminal, the signal transmission module 252 is connected to the single chip microcomputer 251 , and the single chip microcomputer 251 is connected to the servo motor 242 .

[0037] The principle of the present invention is:

[0038] When the present invention is used, the control valve is installed in the pipeline. During the installation process, the installation is carried out according to the installation mark 16. The direction of the installation mark 16 is the direction of water flow. After the installation is completed, the control valve power supply can be turned on.

[0039] During the operation of the control valve, water flows through the water inlet 21 into the swirl device 23. The water is forced to rotate in the swirl device 23, which can drive the mud and sand to rotate with the water body, thereby effectively avoiding blockage caused by mud and sand deposition. The swirl device 23 can be set to one level, and the water flow can be diverted during the process, which is equivalent to an elbow and can be used as an elbow, which is more convenient to use. At the same time, the swirl device 23 can also be set to multiple levels, so that the swirl effect on the water flow is better and the blockage is more effectively avoided. However, it should be noted that for swirl devices 23 with different numbers of levels, the position of the water inlet 21 may change accordingly. Therefore, in the actual setting, the position of the slot 14 should also change accordingly.

[0040] During the swirl process, the swirl motor 2321 in the swirl controller 232 rotates and drives the permanent magnet B2322 at its front end to rotate continuously. A permanent magnet A2315 that cooperates with the permanent magnet B2322 is provided in the cyclone 231 that cooperates with the swirl controller 232. Therefore, during the rotation of the permanent magnet B2322, due to the effect of magnetic coupling, the permanent magnet A2315 also rotates. Since the permanent magnet A is embedded in the impeller 2314, the impeller 2314 rotates, realizing forced rotation of the water flow. It should be noted that during the process, Permanent magnet A2315 is located within the magnetic field range of permanent magnet B2322, so the two can be magnetically coupled. At the same time, in order to ensure the strength of the torque during magnetic coupling, a suitable distance is required between permanent magnet A2315 and permanent magnet B2322. When the distance is too far, the magnetic coupling strength is weak, and the impeller 2314 rotates slowly or does not rotate, affecting the swirl effect on the water flow. When the distance is too close, it will also affect the flow of water. In actual applications, reasonable settings need to be made based on the diameter of the water inlet 21, etc. Since it only involves size adjustment, it will not be repeated here.

[0041] The water flow after the vortex flows into the valve core device 24. At this time, the water flow is in a rotating state, so no sediment deposition will be generated in the valve core device 24, thereby effectively avoiding the blockage of the control valve. By controlling the opening of the valve core 244 of the valve core device 24, the water flow in the pipeline can be regulated. In actual use, the control valve of the present invention is combined with the flow meter to achieve accurate control of the water flow in the pipeline. The use of the control valve and the flow meter in combination to achieve flow control is a mature technology in the field. It is not difficult for those skilled in the art to understand. At the same time, it does not belong to the specific content of the present invention and will not be repeated here.

[0042] In the process of adjusting the opening of the valve core 244, the remote control terminal transmits a signal to the signal transmission module 252, the signal transmission module 252 receives the signal and transmits the signal to the single-chip computer 251, and the single-chip computer 251 controls the servo motor 242 to rotate forward and reverse, thereby realizing the rise or fall adjustment of the valve core 244, thereby realizing the adjustment of the opening of the valve core 244, and then realizing the adjustment of the water flow rate. At the same time, the valve core 244 adopts the form of a plate, which is not easy to be blocked during the process, thereby improving the stability of use. At the same time, in order to ensure the sealing of the valve core 244, a sealing mechanism 245 is provided on the valve core 244 to avoid leakage of the valve body 2 during the movement of the valve core 244.

[0043] As for the sealing mechanism 245, a fitting groove 26 is provided on the valve body 2. The longitudinal width of the fitting groove 26 should be consistent with the longitudinal width of the valve core 244, and a sealing layer 2441 is coated on the front and rear sides and the lower bottom surface of the valve core 244, thereby ensuring the sealing of the valve core 244 at the front and rear sides and the bottom where the valve body 2 is in contact. The sealing layer 2441 can be made of beef tendon, etc., which has good toughness and processability and can be bonded to the valve core 244. At the same time, the sealing effect is also guaranteed and it has a good service life. At the fitting groove 26, the pressure plate 2451 is pressed The sealing ring 2452 is deformed. The sealing ring 2452 can be made of a rubber ring or the like, which has good deformation ability. Therefore, the deformed sealing ring 2452 presses the valve core 244, thereby realizing the seal between the fitting groove 26 and the valve core 244. In addition, during the up and down movement of the valve core 244, the fitting groove 26 fits the shape of the valve core 244, thereby limiting the valve core 244, so that the valve core 244 can rise or fall stably under the drive of the servo motor 342, effectively avoiding the deflection and twisting of the valve core 244, and making the adjustment more stable and reliable.

[0044] Since existing irrigation is intermittent irrigation, the time for sediment deposition mainly occurs when there is no water flow in the water pipe. In the anti-clogging control valve of the present invention, the swirl device 23 is always in operation, thereby always disturbing the water flow near the valve body. Although a small amount of sediment will be deposited during the process of no water flow, this sediment will not form dirt and adhere to the valve body. Therefore, when water is passed again, this sediment will continue to flow away with the water flow and will not cause blockage at the valve core 244.

[0045] Application Example 1

[0046] A vegetable greenhouse, covering an area of ​​1 mu (666.7m 2 ), the greenhouse adopts modern drip irrigation for irrigation. The irrigation water source is river water, which is introduced into the grit chamber for sedimentation to remove large particles of impurities in the river water. After sedimentation, the water is introduced into the greenhouse through the main water pipe. No other treatment is performed during the process. The anti-clogging remote control valve of the present invention is installed on the main water pipe. After the river water and fertilizer are mixed, they are dispersed to the ridges through the dripper.

[0047] In winter, from October to December, the weather turns cooler and the water consumption of vegetable plants decreases. The diameter of the main water pipe is 50 mm. The average flow rate of water in the main water pipe is measured to be about 20 mm / s, and the monthly water consumption is 6 to 8 cubic meters. The water flow rate in the main water pipe is low. During the use of the remote control valve, the control of water volume is stable, and drip irrigation is carried out stably without blockage. After the investigation, the remote control valve was removed for observation, and there was no sediment deposition in the valve body.

[0048] Application Example 2

[0049] An orchard with an area of ​​10 mu (approximately 16 acres) is irrigated using a drip irrigation system. River water is used as the irrigation water source. The river water is introduced into a grit chamber for sedimentation to remove large particles of impurities. After sedimentation, the water is introduced into the orchard through a main water pipe without any other treatment. The anti-clogging remote control valve of the present invention is installed on the main water pipe. After mixing the river water with fertilizer, the water is dispersed to the roots of the fruit trees through the dripper.

[0050] From June to August, due to the hot weather, the orchard has a large water demand, with water consumption of about 15 cubic meters per acre. The diameter of the main water pipe is 100 mm, and the average flow rate of the main water pipe is about 50 mm / s. The water flow rate is faster than that in Application Example 1. During the operation of the remote control valve, the control valve is stable and accurate control of the water flow is achieved. During this period, drip irrigation is carried out stably without blockage. After the trial, the remote control valve is removed for observation, and no sediment is deposited in the valve body.

[0051] Application Example 3

[0052] A municipal park uses collected rainwater to irrigate plants in the park to achieve comprehensive utilization of water resources. Rainwater contains a lot of impurities, and fine processing will significantly increase costs, which is not conducive to resource conservation. The anti-clogging remote control valve of the present invention is used to control and adjust the water volume.

[0053] In the rainy summer season, the sediment content in the rainwater collection system is high. In order to control costs, the rainwater is introduced into the park through the main water pipe after coarse filtration. The anti-clogging remote control valve of the present invention is installed on the main water pipe and operated for one week. During the operation, the operating status is observed in real time. The remote control valve is stable in use and there is no obvious blockage. After use, the remote control valve of the present invention is disassembled. A small amount of sediment remains on the valve body. The valve body is held and slowly moved in clean water, and the sediment in the valve body is taken out. The sediment is flowable and does not adhere to the valve body.

[0054] The remote control valve was reinstalled on the main water pipe, and then no irrigation operation was performed. The swirl device in the anti-clogging remote control valve of the present invention was kept in the open state. After one week, the remote control valve was removed, and a small amount of sediment was found on the valve body. The valve body was placed in clean water and moved slowly, and the sediment was brought out. This shows that the sediment is flowable and does not adhere to the valve body, so it does not affect the stable use of the control valve during irrigation again.

[0055] Comparative Example 1

[0056] Compared with Application Example 1, in another vegetable greenhouse adjacent to Application Example 1, the same water source as that in Application Example 1 is used, and an ordinary remote control valve is used, and the remote control valve does not have an anti-clogging function.

[0057] After more than a month of use, the above-mentioned ordinary remote control valve became clogged. The ordinary remote control valve was disassembled for observation, and mud and sand were found to be deposited at the valve core. After careful observation, it was found that, especially during the interval between two waterings, due to the lack of water flow in the main water pipe, mud and sand would be deposited at the valve core and affect the operation of the control valve next time. The long-term accumulation led to blockage.

[0058] In response to the above situation, the water source was processed again and further filtered using a filter. After the water source was filtered, the blockage phenomenon was alleviated. However, after the investigation was completed, the ordinary remote control valve was removed and compared with the remote control valve of the present invention. The ordinary remote control valve still had a small amount of sediment deposition. It can be expected that as the use time increases, the ordinary remote control valve will still inevitably become blocked.

[0059] Comparative Example 2

[0060] Compared with Application Example 3, the water source of the rainwater collection system is subjected to the same coarse filtration treatment and then introduced into the park through the main water pipe. During the process, an ordinary remote control valve without anti-clogging function is used to control the water flow.

[0061] As time went on during the operation, after three days, the control valve became obviously blocked, the water output was significantly reduced, and the adjustment was sluggish. In order to avoid further blockage of the valve body, the remote control valve was removed and cleaned. During the cleaning process, it was found that some sludge was attached to the valve body, which caused great difficulties in cleaning. After the valve body was cleaned, it was installed back into the main water pipeline and continued to operate for two days.

[0062] After the operation was completed, irrigation was stopped. A week later, the valve body was removed for observation. A large amount of silt deposited in the valve body caused great difficulties in the operation of the control valve. At the same time, cleaning was time-consuming and labor-intensive, and sludge adhesion and blockage occurred, making it unsuitable for practical application.

[0063] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
