Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a quantitative given delay valve. Background Technology

[0002] Valves play a crucial role in industrial production and many systems involving fluid control. The quantitative time-delay valve, a special type of valve, is used to precisely control fluid flow and open or close according to a set time delay. It is widely used in chemical, petroleum, and automated production lines.

[0003] However, existing quantitative delay valves have revealed a series of problems that urgently need to be addressed during practical use. First, when the valve body is damaged due to prolonged use, external impact, or internal corrosion, there is a lack of an effective self-closing mechanism. Once the valve body is damaged, fluid will leak uncontrollably, which not only wastes resources but may also cause serious safety accidents in some hazardous chemical or high-pressure fluid transportation scenarios. Second, fluids often contain various impurities, such as particles, debris, and rust. Most existing quantitative delay valves lack a complete impurity filtration function. These impurities enter the valve with the fluid, easily causing wear and jamming of internal valve parts, thus affecting the normal opening and closing of the valve and the accuracy of flow control.

[0004] To address this, a quantitative time delay valve is proposed. Utility Model Content
