Technical Field
[0001] This utility model relates to the field of valve technology, specifically a valve for water conservancy pipelines. 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. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, with functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to various valves used in extremely complex automatic control systems, with a wide variety of types and specifications.
[0003] Currently, ball valves are widely used in water conservancy pipelines due to their simple structure and good sealing performance. However, traditional ball valves usually only have basic on / off functions and cannot meet the needs of complex water conservancy systems for flow regulation and backflow prevention. In addition, the sealing performance of traditional ball valves is prone to decline after long-term use, leading to leakage problems. Especially under high pressure and high flow conditions, the wear and aging of the sealing gasket will further affect the reliability of the valve. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model, through the design of a valve ball located inside the valve body and multiple through holes arranged opposite each other on the outside of the valve ball, enables the valve to not only control the flow of water but also to precisely regulate the flow rate by adjusting the opening and closing degree of the through holes through rotating the valve ball. This design integrates the functions of flow regulation and on / off control, reducing the number and complexity of valves in the pipeline system.

Detailed Implementation
[0020] 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.
[0021] Please see Figure 1-5 This utility model provides a technical solution: a valve for water conservancy pipelines, including a valve body 1, a valve ball 14 inside the valve body 1, and multiple through holes 11 on the outside of the valve ball 14, arranged opposite to each other. Multiple sealing gaskets 12 are installed inside the valve body 1, and all sealing gaskets 12 are in contact with the valve ball 14. Through the valve ball 14, the valve body 1, and the multiple through holes 11 arranged opposite to each other, the valve can not only control the flow of water, but also adjust the opening degree of the through holes 11 by rotating the valve ball 14, thereby achieving… The design integrates flow regulation and on / off control functions to achieve precise flow regulation, reducing the number and complexity of valves in the pipeline system. Multiple sealing gaskets 12 installed inside the valve body 1 contact the valve ball 14, ensuring a tight fit between the valve ball 14 and the valve body 1. This multi-point contact sealing design effectively prevents water leakage, especially under high pressure and high flow conditions, where the sealing performance is more stable and reliable. The valve ball 14 and sealing gaskets 12 are made of corrosion-resistant and wear-resistant materials, which can withstand the impact of high pressure and high-speed water flow during long-term use, extending the service life of the valve.
[0022] The valve body 1 has an inlet pipe 2 installed on its outer surface. The end of the inlet pipe 2 away from the valve body 1 is equipped with a first connecting pipe 3. The design of the inlet pipe 2 and the first connecting pipe 3 allows the valve to be easily connected to an external pipeline system, improving the ease of installation. The first connecting pipe 3 can be selected with pipes of different specifications or materials according to actual needs, enhancing the applicability and flexibility of the valve.
[0023] The valve body 1 has a drain pipe 4 installed on its outer surface. A second connecting pipe 5 is installed at the end of the drain pipe 4 away from the valve body 1. The design of the drain pipe 4 and the second connecting pipe 5 enables the valve to discharge water efficiently, making it suitable for various water conservancy scenarios, such as drainage systems and irrigation systems. The modular design of the second connecting pipe 5 facilitates connection with pipes of different specifications, improving the versatility and adaptability of the valve. The structural design of the drain pipe 4 optimizes the water flow path, reduces water resistance, and improves drainage efficiency. Furthermore, during the high-speed water output process, it can flush the through hole 11, thus preventing the through hole 11 from becoming blocked and ensuring the reliability of the valve.
[0024] The first connecting pipe 3 is equipped with a first connecting flange 8 at the end away from the water inlet pipe 2. The first connecting flange 8 has multiple first mounting holes 9 on its outside. The design of the first connecting flange 8 and the first mounting holes 9 allows the valve to be quickly and securely connected to the external pipeline by bolts or other fasteners, which improves the efficiency and reliability of installation. The flange connection method has good sealing performance and can effectively prevent leakage at the connection, which is especially suitable for high pressure and high flow conditions.
[0025] The second connecting pipe 5 is equipped with a second connecting flange 6 at the end away from the drain pipe 4. The second connecting flange 6 has multiple second mounting holes 7 on its outside. The design of the second connecting flange 6 and the second mounting holes 7 enables the drain pipe 4 to be quickly and securely connected to the external piping system, further improving the valve's installation efficiency and sealing performance. The flange connection method is suitable for various working conditions, especially in scenarios that require frequent disassembly and installation, and has significant advantages.
[0026] The valve body 1 is equipped with a valve core fixing shaft 13. The end of the valve core fixing shaft 13 near the valve ball 14 is connected to the valve ball 14. The design of the valve core fixing shaft 13 enables the valve ball 14 to be stably fixed inside the valve body 1, preventing the valve ball 14 from shifting or vibrating under the impact of high-pressure water flow, thus improving the stability and reliability of the valve.
[0027] The valve body 1 has a sealing cover 10 installed on its outer surface. A valve stem 15 is located above the sealing cover 10. A handle 16 is installed at the top of the valve stem 15. The bottom end of the valve stem 15 passes through the valve body 1 and is connected to the valve ball 14. The design of the sealing cover 10 effectively prevents water from leaking through the gap between the valve stem 15 and the valve body 1, thus improving the sealing performance of the valve. The design of the valve stem 15 and the handle 16 allows the valve to be manually operated to rotate the valve ball 14, thereby controlling the flow of water and the flow rate. The operation is simple and convenient.
[0028] Working principle: During use, manually rotating the handle 16 will rotate the valve stem 15 and the valve ball 14, thereby opening and closing the valve and regulating the flow. When the valve ball 14 rotates to align the through hole 11 with the inlet pipe 2 and the drain pipe 4, water can flow through the valve, achieving a flow state. When the valve ball 14 rotates to the point where the through hole 11 is misaligned with the inlet pipe 2 and the drain pipe 4, the water flow is blocked, achieving a flow interruption state. By rotating the valve ball 14, the opening degree of the through hole 11 can be adjusted, thereby controlling the amount of water flowing through. For example, partially rotating the valve ball 14 can partially open the through hole 11, achieving precise flow regulation. The inlet pipe 2 and the drain pipe 4 are connected to external pipes through the first connecting pipe 3 and the second connecting pipe 5, respectively. The first mounting hole 9 and the second mounting hole 7 on the first connecting flange 8 and the second connecting flange 6 are fixed to the external pipes with bolts or other fasteners to ensure the tightness and stability of the connection.
