Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to an intelligent flow and pressure regulating valve. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be divided into shut-off valves, check valves, regulating valves, etc. They can also be classified according to the type of their opening element, such as ball valves, butterfly valves, gate valves, etc. Flow regulating and pressure regulating valves are valves that integrate flow regulation and pressure control functions, widely used in fluid transport systems to achieve precise management of the flow rate and pressure of the medium within the pipeline.

[0003] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: when the existing flow regulating valves draw water from natural water sources containing impurities and direct it to irrigate farmland, the natural water sources often contain fallen leaves. When the fallen leaves pass through the flow regulating valves, they can easily adhere to the valve core. After a period of use, this can easily cause the valve core to rotate and become blocked or clogged, affecting the flow of water. It often requires disassembly and cleaning, has a short maintenance cycle, and is relatively inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings and deficiencies of existing technologies by providing an intelligent flow and pressure regulating valve that is not easily clogged and is easy to maintain.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent flow regulating and pressure regulating valve, comprising a valve body and a threaded valve cover detachably disposed on the top surface of the valve body, wherein a threaded rod extending into the valve body is penetrated and engaged on the threaded valve cover, and a valve core that can seal the inner cavity of the valve body is provided at the bottom end of the threaded rod, wherein an impurity filter is detachably embedded in the inner wall of the water inlet end of the valve body, and water impurities are filtered through the impurity filter and retained on the impurity filter.

[0006] A further improvement is that a signal motor is fixedly installed on the top surface of the threaded valve cover and fixedly connected to the top end of the threaded rod.

[0007] A further improvement is that both ends of the valve body are equipped with connecting flanges.

[0008] A further improvement is that the impurity filter includes a detachable connecting block embedded in the inner wall of the valve body inlet and a filter cover structure slidably disposed on the inner wall of the connecting block, wherein a limiting block is integrally formed on the inner edge of the connecting block.

[0009] A further improvement is that the top outer wall of the connecting block is provided with several sealing rings.

[0010] A further improvement is that a lifting ring is provided on the top surface of the connecting block.

[0011] A further improvement is that a spring is provided between the limiting block and one side of the filter cover structure.

[0012] A further improvement is that the filter cover structure includes an arc-shaped filter cover protruding towards the water inlet end of the valve body and sliders disposed at both ends of the arc-shaped filter cover.

[0013] A further improvement is that the raised surface of the arc-shaped filter cover is provided with several spikes.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When this utility model is used, if the introduced water flow contains a lot of impurities such as leaves, the impurity filter can retain the impurities on the arc-shaped filter cover, and the water flow pressure can push the impurities to the edge of the arc-shaped filter cover, keeping the middle position of the arc-shaped filter cover unobstructed, preventing blockage, and avoiding impurities from getting stuck in the valve core position, which greatly extends the maintenance time. At the same time, when performing maintenance, the impurity filter can be directly pulled out for cleaning without disassembling the valve, making maintenance simpler and more convenient.

[0020] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0021] See Figure 1-4As shown, the technical solution adopted in this specific embodiment is: an intelligent flow regulating and pressure regulating valve, including a valve body 1 and a threaded valve cover 2 detachably disposed on the top surface of the valve body 1. A threaded rod 3 extending into the valve body 1 is penetrated and engaged on the threaded valve cover 2. A valve core 4 that can seal the inner cavity of the valve body 1 is provided at the bottom end of the threaded rod 3. An impurity filter 6 is detachably embedded in the inner wall of the water inlet end of the valve body 1. The impurity filter 6 includes a connecting block 61 detachably embedded in the inner wall of the water inlet end of the valve body 1 and a slidably disposed on the connecting block 61. The filter cover structure 63 on the inner wall of the connecting block 61 includes an arc-shaped filter cover 21 protruding towards the water inlet end of the valve body 1 and sliders 22 disposed at both ends of the arc-shaped filter cover 21. A limiting block 64 is integrally formed on the inner edge of the connecting block 61. Water impurities are filtered through the impurity filter 6 and retained on the impurity filter 6. In use, the valve body 1 is connected to the pipeline, with the side with the impurity filter 6 as the water inlet end, and water can then be introduced, allowing the water to flow through the valve body 1, in conjunction with the rotating threaded rod 3. The valve core 4 is raised and lowered to open and close the valve, and the rising height of the threaded rod 3 can be controlled to control the pressure and flow rate of the water. If the water flow contains a lot of impurities such as leaves, when the water flows through the arc-shaped filter cover 21 of the impurity filter 6, the impurity filter 6 retains the impurities on the arc-shaped filter cover 21, and the water pressure pushes the impurities to the edge of the arc-shaped filter cover 21, keeping the middle position of the arc-shaped filter cover 21 unobstructed, preventing blockage, and avoiding impurities from getting stuck in the valve core 4, which greatly extends the maintenance time. At the same time, when performing maintenance, the connecting block 61 can be pulled up directly, so that the connecting block 61 is pulled up and the inner wall of the valve body 1 is squeezed against the arc-shaped filter cover 21, so that it is pressed into the inner cavity of the connecting block 61 through the slider 22. At this time, the connecting block 61 and the arc-shaped filter cover 21 can be pulled out for cleaning. After cleaning, the connecting block 61 can be reinserted into the valve body 1 for reuse. During maintenance, there is no need to disassemble the valve, making maintenance simpler and more convenient.

[0022] The top surface of the threaded valve cover 2 is fixedly provided with a signal motor 5 that is fixedly connected to the top end of the threaded rod 3. This facilitates the reception of external signals through the signal motor 5, thereby enabling the automatic rotation of the threaded rod 3, resulting in a higher degree of intelligence and automation, and more precise control of water pressure and flow.

[0023] Both ends of the valve body 1 are provided with connecting flanges 7, which makes it easier to connect the valve body 1 to the pipeline;

[0024] The top outer wall of the connecting block 61 is provided with several sealing rings 62, which helps to improve the sealing effect of the connecting block 61 and prevent water leakage;

[0025] The top surface of the connecting block 61 is provided with a lifting ring 66, which makes it easier and less strenuous to lift the connecting block 61.

[0026] A spring 65 is provided between the limiting block 64 and one side of the filter cover structure 63, which is beneficial for the filter cover structure 63 to be pressed in and then popped back to its original position by the spring 65, preventing the filter cover structure 63 from getting stuck in the connecting block 61 after removal and making it difficult to clean.

[0027] The arc-shaped filter cover 21 has several spikes 23 on its raised surface. When thinner impurities such as leaves enter, they are pushed to the edge of the arc-shaped filter cover 21 by the water flow, come into contact with the spikes 23 and are broken up. This allows the impurities to be compressed more effectively, thereby preventing leaves from accumulating and clogging the filter quickly and extending the maintenance cycle.

[0028] The working principle of this utility model is as follows: When using this utility model, the valve body 1 is connected to the pipeline, with the side containing the impurity filter 6 as the water inlet. Water can then be introduced and allowed to flow through the valve body 1. The valve core 4 is raised or lowered by rotating the threaded rod 3, thereby opening and closing the valve. The height of the threaded rod 3 can be controlled, thus controlling the pressure and flow rate of the water. If the introduced water contains a large amount of impurities such as leaves, when the water flows through the arc-shaped filter cover 21 of the impurity filter 6, the impurity filter 6 retains the impurities on the arc-shaped filter cover 21, and the water pressure pushes the impurities towards the edge of the arc-shaped filter cover 21. Keeping the middle position of the arc-shaped filter cover 21 unobstructed prevents blockage and avoids impurities from getting stuck in the valve core 4, significantly extending maintenance time. During maintenance, the connecting block 61 can be pulled upwards directly, causing the inner wall of the valve body 1 to press the arc-shaped filter cover 21 into the inner cavity of the connecting block 61 via the slider 22. At this point, the connecting block 61 and the arc-shaped filter cover 21 can be pulled out for cleaning. After cleaning, the connecting block 61 can be reinserted into the valve body 1 for reuse. Maintenance does not require disassembling the valve, making maintenance simpler and more convenient.
