Intelligent zero flow rate check valve is a type of check valve that can track the flow rate of the medium. It has the opening and closing characteristics of an axial flow check valve and good dynamic characteristics. The valve opening, pressure, and flow rate are collected by sensors and control modules, and the matching degree between the valve action and the system is monitored in real time. Based on the actual effect of water hammer protection, the valve opening and closing characteristics are independently optimized.
feature
1. The valve consists of a valve body, guide body, and valve disc that conform to the principle of the Venturi tube flow channel, a pressure adjustable tracking spring, as well as sensors and control modules for monitoring. It has extremely low full opening resistance and ultra short stroke switching characteristics.
2. This product is not a traditional quick closing check valve or slow closing check valve, but a check valve that autonomously matches the system flow rate and automatically finds the most suitable closing characteristics. Its closing characteristics are matched in real-time with the operating conditions of the water delivery system.
3. The valve performs hydraulic simulation calculations in the background based on real-time collected pressure wave signals, as well as synchronized valve opening and flow signals, comparing the actual water hammer effect to find the most suitable closing rate for the current system, minimizing water hammer, and preventing medium backflow.
4. This valve is used in conjunction with the water hammer elimination tank, which can maximize the elimination of water hammer while maximizing the utilization of the volume of the water hammer elimination tank, effectively reducing system operating costs.
