What is the principle of the offset valve explained by the fluorine lined check valve manufacturer?

check valve The manufacturer explains that the principle of the imbalance valve is the reverse adjustment inside the valve body

The principle of an imbalance valve is the reverse regulation inside the valve body. When the pressure at the outlet increases, it actively reduces the diameter and narrows the flow rate transition, and vice versa. If reversed, this set of conditioning fragments will not work. And the valve plate that plays a regulating role is non directional, with reverse pressure that can reduce or even open the flow. Since the device's malfunction valve is for better insulation, it does not have the effect of reverse installation. If it is reverse, it is an artificial fallacy, PTFE lined valve I will definitely make corrections. The offset valve belongs to the scope of regulating valves, and its working principle is to change the gap (i.e. opening) between the valve core and the valve seat, and to clamp the valve Fluorine-lined Butterfly Valve Improving the way fluid passes through the stagnant barrier of the valve and reaches the regulated flow rate. The imbalance valve is equivalent to a dieting component that can improve all barriers, and can be obtained from the flow equation for no compressible fluid.
　　
Kv is the valve coefficient of the offset valve. Its definition is: the flow rate (m3/h) passing through the offset valve when the differential pressure of the offset valve is always 1 bar (about 1 kgf/cm2). The valve coefficient when the imbalance valve is fully opened is equal to the stagnant power of a general valve. If the opening degree of the imbalance valve does not change, then the valve coefficient Kv does not change, which means that the valve coefficient Kv is determined by the opening degree. After actual testing, it was found that there was no valve coefficient at the same opening, and the imbalance valve can be used as a capacity regulating flow control component.
　　
When adjusting the imbalance of the pipeline network, use a hose to connect the pressure measuring small valve of the adjusted imbalance valve to the public intelligent measuring tool, Fluorine lined DC globe valve The measuring tool can display the flow rate value (and pressure drop value) passing through the valve. After communicating with the measuring tool human-machine interface, the vector tool outputs the requested flow rate value at the misaligned valve. The measuring tool then plans, synthesizes, and obtains the opening value of the valve when the pipeline reaches hydraulic misalignment. Imbalance valves belong to the scope of regulating valves, and their task principle is to change the gap between the valve core and valve seat, change the way fluid passes through the stagnant barrier of the valve, and reach the means of regulating flow.
