Description

Technical Field

[0001] This utility model relates to the technical field of control valves, specifically a filter membrane type intelligent water level precision control valve. Background Technology

[0002] When adding water to a water tank or pool, the traditional approach is to rely on real-time manual monitoring to ensure a continuous supply of water from the outside source and prevent the water level from becoming too low or too high. However, this method has significant inconveniences and drawbacks. In environments where water is added on a large scale or frequently, the workload of manual monitoring is enormous and prone to human error. At the same time, the cost of manual monitoring is high, requiring a large amount of human resources, which leads to a significant increase in operating costs.

[0003] To overcome the above-mentioned defects, the prior art (Chinese patent CN214838788U, published on November 23, 2021) provides a hydraulic water level control valve, including a control valve, an inlet pipe embedded at the bottom of the control valve, an outlet pipe embedded near the middle position on the outer circumference of the control valve, a sealing cover above the annular groove, a valve cover mounted on the upper surface of the sealing cover, a valve stem at the middle position of the outer valve, a connecting column on one side of the outer valve, a flipping rod in the middle of the connecting column, the flipping rod connected to the valve stem via a flipping shaft, a float at the end of the flipping rod, and a float ball at the bottom of the float. In this hydraulic water level control valve, the inlet pipe cooperates with the first flange to facilitate quick and secure connection to an external water pumping pipe, and the outlet pipe cooperates with the second flange to facilitate quick and secure connection to a water storage tank. The valve stem and sealing plug cooperate on the outer valve to control the connection between the outlet pipe and the inlet pipe. The combination of the flipping rod and the float, with the assistance of the float ball, fixes the position of the sealing plug by the rising position of the float ball, thus controlling water storage.

[0004] While existing technologies can automatically control water levels through control valves, the float tubes installed during operation can cause the float to move up and down, resulting in inaccurate water level control and affecting the normal operation of the valve. Furthermore, the overall mechanical movement of the valve stem controlled by the float is easily affected by impurities and sediments in the water, which may cause the float to get stuck or obstruct the movement of the valve stem, thus affecting the normal operation of the valve.

[0005] To address the aforementioned issues, there is an urgent need for innovative design based on the existing filter membrane type intelligent water level precision control valve. Therefore, we proposed that the filter membrane type intelligent water level precision control valve can effectively solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a filter membrane type intelligent water level precision control valve to solve the problems mentioned in the background art. In the current market, water level automatic control is achieved through control valves, where the float tube can easily cause the float ball to move up and down, resulting in inaccurate water level control and affecting the normal operation of the valve. Furthermore, the overall mechanical movement of the valve stem controlled by the float ball is easily affected by impurities and sediments in the water, which may cause the float ball to get stuck or hinder the movement of the valve stem, thus affecting the normal operation of the valve.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a filter membrane type intelligent water level precision control valve, comprising a control valve body, a valve core installed inside the control valve body, a through groove opened inside the valve core, the upper end of the valve core being connected to the inside of the control valve body by a first spring, a ball valve connected to the top of the control valve body by a second conveying pipe, a float ball connected to the ball valve, a first through hole opened on the valve core, and a second transmission pipe connected to the bottom of the control valve body, the filter membrane body being installed inside the second transmission pipe.

[0009] Preferably, the through groove is connected to the inner cavity of the control valve body cover, the inner cavity of the control valve body cover is connected to the second delivery pipe, the valve core moves toward the control valve body cover and then connects to the inner cavity of the control valve body through the through groove, and the inner cavity of the control valve body is connected to the first delivery pipe.

[0010] Preferably, an auxiliary component is installed inside the second transmission pipe, the auxiliary component including a support plate installed inside the second transmission pipe.

[0011] Preferably, a lifting component is connected through the inside of the support plate, and a baffle is installed on the top of the lifting component, with the baffle located on the upper surface of the support plate.

[0012] Preferably, a second through hole is provided through the support plate, the diameter of the baffle is larger than the diameter of the second through hole on the support plate, and a second spring is provided on the outside of the lifting component.

[0013] Preferably, a screw is provided at the upper end of the baffle, and a sleeve is connected to the outside of the screw via a rotating ball. The sleeve is rotatably connected to the filter membrane body.

[0014] Preferably, a cleaning element is provided on the side end of the sleeve, and the cleaning element is located on the upper surface of the filter membrane body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This filter membrane type intelligent water level precision control valve filters the liquid through the filter membrane body, thereby effectively intercepting impurities and particles in the liquid, preventing damage caused by impurities entering the control valve body, reducing equipment failure and maintenance costs. The float controls the connection of the second delivery pipeline, and the valve is opened and closed by adjusting the internal pressure of the control valve body. Overall, this reduces the problem of poor stability caused by the float directly controlling the valve core. The specific details are as follows:

[0016] (1) The liquid is filtered through the filter membrane body to prevent impurities from entering the control valve body and causing damage, thus reducing equipment failure and maintenance costs. The float controls the connection of the second delivery pipeline and the valve body is opened and closed by adjusting the internal pressure, which reduces the problem of poor stability caused by the float directly controlling the valve core. The whole system does not require frequent manual intervention, thus reducing labor costs.

[0017] (2) The manual valve makes it easy to operate manually when the float is damaged, which enhances the reliability and safety of the system. The liquid is transported through the second through hole on the baffle, which reduces the overall pressure of the transported liquid and reduces the problem of damage to the filter membrane body caused by high pressure of the transported liquid.

[0018] (3) When the second spring on the outside of the lifting component is squeezed, the liquid is transported through the second through hole. The whole system uses water flow power to automatically open the liquid transport. The whole system does not require an additional power source, which is energy-saving and environmentally friendly. When the water flow is turned off, the support plate blocks the second through hole on the baffle, thereby automatically closing the channel after the water flow stops, preventing liquid backflow.

[0019] (4) When the baffle moves upward, the screw at the top of the baffle moves upward. The overall structure is simple, which not only makes it convenient for later maintenance, but also reduces the problem of increased costs caused by setting up extra structures.

[0020] (5) The screw drives the outer sleeve to rotate on the filter membrane body through the rotating ball at the side end. The cleaning part on the outside of the sleeve can easily clean the filter membrane body, thereby realizing the automatic cleaning function of the filter membrane body, reducing the workload and cost of manual cleaning and maintenance.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1: In this example, the float 9 closes the ball valve 8, cutting off the connection of the second delivery pipe 6. This reduces the problem of poor stability caused by the float 9 directly controlling the valve core 3, and improves the service life of the control valve body 1. Figures 1-5The technical solution shown includes a control valve body 1, a valve core 3 installed inside the control valve body 1, a through groove 4 inside the valve core 3, the upper end of the valve core 3 connected to the inside of the control valve body 1 by a first spring 5, a ball valve 8 connected to the top of the control valve body 1 by a second conveying pipe 6, a float ball 9 connected to the ball valve 8, a first through hole 10 on the valve core 3, a second transmission pipe 12 connected to the bottom of the control valve body 1, a filter membrane body 13 installed inside the second transmission pipe 12, a first conveying pipe 2 provided on the side of the control valve body 1, a manual valve 7 installed on the second conveying pipe 6, a first transmission pipe 11 connected to the side of the first conveying pipe 2, and the through groove 4 connecting to the valve cover of the control valve body 1. The control valve body 1 is connected to the valve cover cavity, which is connected to the second delivery pipe 6. After the valve core 3 moves towards the valve cover of the control valve body 1, it connects to the inner cavity of the control valve body 1 through the through groove 4. The inner cavity of the control valve body 1 is connected to the first delivery pipe 2. The control valve body 1 is easy to install stably. At this time, the ball valve 8 and the float ball 9 are installed in the water tank or pool. Liquid is delivered to the inside of the control valve body 1 through the second transmission pipe 12. At this time, the liquid is filtered through the filter membrane body 13, which effectively intercepts impurities and particles in the liquid, preventing impurities from entering the control valve body 1 and causing damage. This reduces equipment failure and maintenance costs, and facilitates the filtration of the delivered liquid, ensuring water quality. After filtration The liquid is delivered to the control valve body 1, through the through groove 4 in the valve core 3 to the valve cover at the top of the control valve body 1, and then through the second delivery pipe 6 at the top of the valve cover to the ball valve 8. From there, it is delivered to the water tank or pool. At this time, the valve core 3 inside the control valve body 1 moves upward, and the first spring 5 on the valve core 3 is squeezed. The liquid is then delivered through the first through hole 10 on the valve core 3 to the control valve body 1, and output through the first delivery pipe 2. The first delivery pipe 2 is connected to the first transmission pipe 11, facilitating the first transmission pipe 11 to deliver the liquid to the water tank or pool. As a result, the water level in the water tank or pool rises, and the float 9 rises with the water level, reaching the set maximum liquid level. When the float ball 9 closes the ball valve 8, it cuts off the connection of the second delivery pipe 6, which reduces the problem of poor stability caused by the float ball 9 directly controlling the valve core 3 and improves the service life of the control valve body 1. At this time, the internal pressure of the control valve body 1 increases, and the valve core 3 moves downward under the pressure, causing the first delivery pipe 2 to stop supplying water to the water tank or pool. When the water level in the water tank or pool drops, the float ball 9 drops with the water level. At this time, the ball valve 8 is opened by the float ball 9. This cycle continues, and the overall structure is stable, realizing automatic monitoring and control of the water level. The water supply is automatically stopped after the set water level is accurately reached, avoiding water overflow from the water tank or pool, improving the efficiency of water resource utilization, and reducing labor costs by eliminating the need for frequent manual intervention.

[0031] Example 2: In this example, the second through hole 17 on the baffle 15 is blocked by the support plate 16, thereby automatically closing the channel after the water flow stops, preventing liquid backflow, and ensuring the safety and stability of the system operation. Specifically, as shown below... Figures 4-6 As shown, an auxiliary component is installed inside the second transmission pipe 12. The auxiliary component includes a support plate 16 installed inside the second transmission pipe 12. A lifting member 14 is connected through the support plate 16. A baffle 15 is installed on the top of the lifting member 14 and is located on the upper surface of the support plate 16. A second through hole 17 is opened through the support plate 16. The diameter of the baffle 15 is larger than the diameter of the second through hole 17 on the support plate 16. A second spring 18 is provided on the outside of the lifting member 14. A manual valve 7 is provided on the second transmission pipe 6 to facilitate manual operation when the float 9 is damaged, which enhances the reliability and safety of the system. When liquid is transported into the control valve body 1 through the second transmission pipe 12, the lifting member 14 moves upward by the water flow. The lifting member 14 drives the support plate 16 to move upward. When the support plate 16 moves away from the surface of the baffle 15, the liquid is transported through the second through hole 17 on the baffle 15. This reduces the pressure of the transported liquid, thus preventing damage to the filter membrane body 13 caused by excessive liquid pressure. At this time, the second spring 18 on the outside of the lifting component 14 is squeezed, and the liquid transport is automatically started using water flow power. The entire system requires no additional power source, making it energy-saving and environmentally friendly. When the water flow stops, the second spring 18 rebounds, causing the lifting component 14 to return to its initial position. This moves the support plate 16 at the upper end of the lifting component 14 to the surface of the baffle 15, and blocks the second through hole 17 on the baffle 15. This automatically closes the channel after the water flow stops, preventing liquid backflow and ensuring the safety and stability of the system operation.

[0032] Example 3: In this example, the cleaning component 22 facilitates the cleaning of the filter membrane body 13, thereby realizing the automatic cleaning function of the filter membrane body 13, effectively removing impurities attached to the surface of the filter membrane body 13, and maintaining the permeability of the filter membrane body 13, specifically as follows: Figures 4-7As shown, a screw 19 is provided at the upper end of the baffle 15. A sleeve 21 is connected to the outside of the screw 19 via a rotating ball 20. The sleeve 21 is rotatably connected to the filter membrane body 13. A cleaning element 22 is provided on the side end of the sleeve 21, located on the upper surface of the filter membrane body 13. When the baffle 15 moves upward, the screw 19 at the upper end of the baffle 15 moves upward. The overall structure is simple, which not only facilitates later maintenance but also reduces the problem of increased costs caused by the need for additional structures. The screw 19 is rotated at its side end. The ball 20 drives the outer sleeve 21 to rotate on the filter membrane body 13. The cleaning part 22 on the outside of the sleeve 21 facilitates the cleaning of the filter membrane body 13, thereby realizing the automatic cleaning function of the filter membrane body 13, effectively removing impurities attached to the surface of the filter membrane body 13, maintaining the permeability of the filter membrane body 13, extending the service life of the filter membrane body 13, and reducing the workload and cost of manual cleaning and maintenance. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
