The angle type constant water level main valve consists of an angle type diaphragm main valve body, which is internally equipped with a special reinforced nylon diaphragm and a spring, and the opening and closing of the main valve is controlled by the floating ball pilot valve outside the main valve. When the water level in the pool reaches the set water level, the floating ball pilot valve is closed first, and then the main valve is closed. When the water level in the pool drops by about 10 cm, the floating ball pilot valve opens, and then the main valve opens to fill a large amount of water into the pool. The medium temperature is 0- 80C
