Working Principle of Check Valve
The working principle of the check valve essentially relies on the laws of fluid dynamics. Its core function is to regulate the opening and closing of the valve by the pressure of the fluid itself and the weight of the valve disc itself, thereby preventing the fluid from flowing in the opposite direction.
