Description

Technical Field

[0001] The utility model relates to the technical field of regulating valves, in particular to an intelligent regulating valve capable of detecting water pressure. Background Art

[0002] The regulating valve changes the fluid flow rate by using external power. The regulating valve is generally composed of an actuator and a valve. The valve is a control component in the fluid delivery system, and has functions such as cut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief. The application number CN202310423704.9 is retrieved, which is a high-sealing regulating valve that is easy to disassemble. Through this design, while the embedded groove and the valve cover are screwed tightly, the groove notch and the outer wall of the elastic clamp are tightly fitted, so that the elastic clamp tightly clamps the connecting sleeve to ensure the internal sealing of the valve.

[0003] Similar to the above-mentioned high-sealing regulating valve that is easy to disassemble: although the groove notch fits tightly with the outer wall of the elastic clamp, so that the elastic clamp tightly clamps the connecting sleeve to ensure the internal sealing of the valve, but firstly, since the regulating valve will be closed for a long time, it is easy for scale and other impurities to adhere to the surface of the valve plate inside the regulating valve. Long-term accumulation can easily affect the normal lifting of the valve plate. Secondly, the existing regulating valves are often unable to detect the water pressure inside the valve cavity, and cannot control the lifting of the valve plate to control the flow rate by different water pressures.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an intelligent regulating valve capable of detecting water pressure is proposed to achieve a more practical purpose. Utility Model Content
