Description

Technical Field

[0001] The invention relates to the technical field of water valves, and in particular to a combined intelligent anti-blocking water valve with integrated filtering and flow detection. Background Art

[0002] At present, the integrated valves used in the aquaculture industry and the general water-using industry are mostly divided into two types. One is the split type, that is, the external combination type, which is generally composed of a filter plus a solenoid valve plus a flow meter and related pipelines. Its advantages are flexible configuration and maintenance, but it not only takes up a lot of space, but also is inconvenient for on-site construction and maintenance, and even more inconvenient for system integration, and there are also many problems in its applicability to the aquaculture industry. The other is the integrated type, that is, the flow meter and the solenoid valve are made into one, and there are also some integrated filters. Its advantages are that it takes up little space and is modular, which is convenient for on-site installation and use, and is also convenient for configuration inside the setting, which meets the needs of the water-using industry and the aquaculture industry. However, because the water quality of the aquaculture industry is relatively poor, its poor water quality and additives will also cause failures of the solenoid valve and the flow meter, which will greatly increase the use and maintenance costs of the integrated valve;

[0003] Water control systems widely used in the market are mostly pilot solenoid valves, which open the pilot hole after the electromagnet is attracted, allowing water to be pressed into the diaphragm and then open the water valve. Because water in industries such as breeding, water treatment, and animal husbandry contains a lot of impurities or additives, a filter component is generally added before the valve. At the same time, in order to accurately control the water output, a blade flow meter is added before or after the valve to count the water flow pulses. However, the existing pilot solenoid valves are not suitable for livestock water use scenarios with poor water quality. When used, it is easy to cause the pilot hole and diaphragm in the valve body to be blocked and a water film to form, resulting in the valve body being unable to work. At the same time, the existing solenoid valves are difficult to construct, use, and maintain on site.

[0004] Therefore, a combined intelligent anti-water blocking valve with integrated filtration and flow detection is needed to improve the above problems. Summary of the invention

[0033] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The solenoid valve module 300 includes a solenoid valve seat 301, which is embedded in the outer wall of the valve body fixing seat 101, wherein the solenoid valve seat 301 is located directly below the nest-shaped filter block 201, and a conductive needle seat 302 is installed on the outer wall of the solenoid valve seat 301, wherein the conductive needle seat 302 is located in the inner cavity of the valve body fixing seat 101, and an electromagnet coil 303 is installed on one side of the conductive needle seat 302 and on the inner wall of the solenoid valve seat 301, and a conductive magnet bottom plate 304 is installed on one side of the conductive needle seat 302 and on the outer wall of the solenoid valve seat 301, and a conductive magnet bracket 303 is installed on the side wall of the solenoid valve seat 301. 05, a magnetic conductive center block 306 is symmetrically arranged on the outer wall of the solenoid valve seat 301 and with the magnetic conductive magnet support 305, a moving valve core 307 is arranged on one side of the magnetic conductive magnet bottom plate 304 and located on the outer wall of the solenoid valve seat 301, a moving core sealing gasket 308 is arranged on the outer wall of the moving valve core 307, a compression spring 309 is arranged between the moving valve core 307 and the solenoid valve seat 301 and located on the outer wall of the moving valve core 307, and a rectangular array of fixing anti-slip screws 310 is arranged on the outer wall of the solenoid valve seat 301, wherein one end of the fixing anti-slip screw 310 passes through the solenoid valve seat 301 and extends to the inner wall of the valve body fixing seat 101.

[0034] In this embodiment, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The flowmeter module 400 includes a flowmeter seat 401, which is embedded in the inner wall of the valve body fixing seat 101, wherein the flowmeter seat 401 is located directly below the solenoid valve module 300, a flowmeter seat cover 402 is installed on the outer wall of the flowmeter seat 401, a bearing 403 is installed on the inner wall of the flowmeter seat 401, a flowmeter impeller 404 is installed on the outer wall of the bearing 403, magnets 405 are arranged in a circular array on the outer wall of the flowmeter impeller 404, a flowmeter sealing ring 406 is arranged on the outer wall of the flowmeter seat 401, and a fixing anti-slip screw 407 is arranged on the outer wall of the flowmeter seat 401.

[0035] Furthermore, when using it, firstly, according to the water pressure range and the flow rate requirements at the site, the valve seat module 100 and the direct-acting solenoid valve module 300 of suitable diameter should be selected, and then according to the required measurement accuracy, the appropriate flow meter module 400 should be selected, and finally, according to the water quality conditions, the appropriate filter module 200 should be selected, so that the integrated valve suitable for on-site use can be quickly assembled. Even if some requirements are found to be unsatisfactory during use, adjustments and adaptations can be achieved by replacing modules of different specifications.

[0036] Furthermore, during use, if the water valve needs to be opened automatically, the controller controls the direct-acting electromagnet coil 303 to be energized to open the water valve, and the flow meter module 400 counts the water flow. When the controller's water volume count reaches the program requirement, the power of the electromagnet coil 303 is disconnected to shut off the water flow, thereby achieving the purpose of precise control of the outflow of water. At the same time, when the electromagnet coil 303 is energized (when the controller detects that there is current) and the flow meter module 400 does not generate flow counts, it can be determined that there is an abnormal problem of water outage or valve blockage. If the electromagnet coil 303 is not energized and the flow meter module 400 has counts, it is manually controlled or the water valve is faulty. The self-diagnosis function of the integrated valve can be realized through the combination of the two states.

[0037] Furthermore, during use, manual debugging or control of water flow is required. Water can be outflowed by pressing the hand valve manually. When the hand valve is pressed, the water flow rate will be recorded by the controller, so as to achieve all-weather monitoring of water volume. The filter module needs to be cleaned and maintained, which can be maintained regularly or feedback can be obtained through the speed of flow counting. That is, when the filter hole is blocked, the water flow generated after the solenoid valve is opened will be smaller than when it is not blocked. The speed of water flow can be monitored by counting the flow meter by the controller, and when the value of the small flow rate is significantly lower than the normal value, it can be determined that the filter hole is blocked and needs to be cleaned. If the corresponding module is damaged, only the corresponding module needs to be maintained or replaced, which is convenient for on-site use and maintenance time.

[0038] Working process of the present invention: when the intelligent anti-blocking water valve with combined integrated filtration and flow detection designed by the present invention is working, the water will first enter from the water inlet and pass through the filter module 200. The filter module 200 is installed on the valve body fixing seat 101 through the filter anti-slip screws 204. When it needs to be disassembled, maintained and replaced, the screws will not fall out, ensuring the integrity of the module and the convenience of assembly and maintenance. At the same time, after installation, the filter seal ring 202 is used between the nest-shaped filter block 201 and the valve body fixing seat 101 to ensure the sealing of the waterway. Water can only flow into the subsequent waterway after being filtered by the nest-shaped filter block 201, thereby completing the function of filtering water quality. At the same time, by assembling filter modules with different filter mesh sizes and filter materials, the integrated valve can be adapted to different water qualities required for filtering.

[0039] When in use, select the valve seat module 100 and the direct-acting solenoid valve module 300 of appropriate diameter according to the on-site water pressure range and the flow rate requirements, select the appropriate flow meter module 400 according to the required measurement accuracy, and finally select the appropriate filter module 200 according to the water quality conditions, so that an integrated valve suitable for on-site use can be quickly assembled. Even if it is found that some requirements cannot be met during use, adjustments and adaptations can be achieved by replacing modules of different specifications.

[0040] By fixing the solenoid valve module 300 on the valve body fixing seat 101 with the anti-slip screw 310, a solenoid valve sealing ring 103 is arranged between the solenoid valve module 300 and the valve body fixing seat 101 to ensure the sealing of the water flow channel. If the electromagnet coil 303 of the solenoid valve module 300 is not energized and the manual valve is not pressed, the moving valve core 307 and the moving core sealing gasket 308 will be pressed and blocked by the compression spring 309 to block the water flow hole of the integrated valve. The water flow will stop here and no water will flow downward. However, when the electromagnet coil 303 is energized, the magnetic force composed of the electromagnet coil 303, the magnetic base plate 304, the magnetic bracket 305 and the magnetic center block 306 will suck up the moving valve core 307 and the moving core sealing gasket 308, thereby opening the water flow channel and allowing the water to flow downward. When the solenoid coil 303 loses power, the moving valve core 307 and the moving core sealing gasket 308 will be compressed and blocked again by the compression spring 309 to close the water outlet, thus completing the water flow closing.

[0041] During use, if the water valve needs to be opened automatically, the controller controls the direct-acting electromagnet coil 303 to be energized to open the water valve, and the flow meter module 400 counts the water flow. When the controller's water volume count reaches the program requirement, the power of the electromagnet coil 303 is disconnected to shut off the water flow, thereby achieving the purpose of precise control of the outflow of water. At the same time, when the electromagnet coil 303 is energized (when the controller detects that there is current) and the flow meter module 400 does not generate flow counts, it can be determined that there is an abnormal problem of water outage or valve blockage. If the electromagnet coil 303 is not energized and the flow meter module 400 has counts, it is manually controlled or the water valve is faulty. The self-diagnosis function of the integrated valve can be realized through the combination of the two states.

[0042] By paralleling the direct-acting solenoid valve with a manual valve structure integrated in the valve seat module 100, when the manual valve pressure cap 120 is manually pressed, the manual valve pressure rod 119 will overcome the action of the pressure rod return spring 121 and move downward. At the same time, the push pin lever block 116 is hinged on the valve body fixed seat 101 through the lever block rotating shaft 117, and one end of the push pin lever block 116 is hinged to the manual valve pressure rod 119 through the lever block pushing shaft 118. When the manual valve pressure rod 119 moves downward, the manual valve pressure rod 119 is pressed downward. When the push pin lever block 116 is moved, it will drive the push pin lever block 116 to rotate clockwise so that the other end of the lever pushes against the manual push pin 113 and moves horizontally, thereby pushing the moving valve core 307 and the moving core sealing gasket 308, thereby opening the passage for water to flow downward and realizing the manual opening of the water valve. When the effect of the manual valve pressure cap 120 is cancelled, the manual push pin 113 will return to its original position under the effect of the push pin return spring 114, allowing the moving valve core 307 and the moving core sealing gasket 308 to re-tighten and block the water outlet, thus completing the closure of the water flow. Among them, the push pin sealing ring 110, the push pin sealing ring pressing block 111, the pressing block fixing screw 112 and the push pin block sealing ring 115 are used to ensure the sealing and guiding properties of the manual push pin 113. After the water flow channel is opened, it flows from the internal flow channel to the flow meter module 400;

[0043] The flow meter module 400 is also locked to the valve body fixing seat 101 by fixing the anti-slip screw 407. The flow meter sealing ring 406 ensures the seal between it and the valve body fixing seat 101. The flow meter impeller 404 is connected to the flow meter seat 401 by a bearing 403. When water flows through the internal channel, it will drive the flow meter impeller 404 to rotate. At the same time, a magnet 405 is installed at the corresponding position of each blade of the flow meter impeller 404. Every time the magnet 405 rotates to the Hall sensor 109 fixed on the valve body fixing seat 101, a pulse signal will be generated. The more water flows through, the more it can drive the flow meter impeller 404 to rotate, and the more pulse signals generated by the magnet 405 and the Hall sensor 109, that is, the corresponding Hall pulse number is in a certain proportional relationship with the water flow rate, so that the outflowing water flow rate is counted by the total number of pulses of the Hall sensor 109, and then the outflowing water amount can be accurately controlled. Further downward is a joint structure consisting of a water outlet joint nut 104, a joint nut buckle block 105 and a water outlet sealing ring 106, which facilitates installation and replacement of the relevant water channels on site;

[0044] At the same time, during use, manual debugging or control of water flow is required. You only need to press the hand valve manually to achieve water outflow. When the hand valve is pressed, the water flow passing through will also be recorded by the controller, so as to achieve all-weather monitoring of water volume. The filter module needs to be cleaned and maintained, which can be maintained regularly or feedback can be obtained through the speed of flow counting. That is, when the filter hole is blocked, the water flow generated after the solenoid valve is opened will be smaller than when it is not blocked. The speed of the water flow can be monitored by counting the flow meter by the controller, and when the value of the small flow speed is significantly lower than the normal value, it can be determined that the filter hole is blocked and needs to be cleaned; if the corresponding module is damaged, you only need to maintain or replace the corresponding module, which is convenient for on-site use and maintenance time.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
