Working principle:
1. It consists of valve body shell, diaphragm, regulating switch, inlet and outlet and water outlet.
2. The water inlet pipe is connected with the hose, and the water outlet pipe is extended into the drinking water tank with steel pipes.
3. The diaphragm is installed in the inner cavity of the shell to divide the valve body into two closed inner cavities.
Fourthly, when the water level in the water tank is lower than the water outlet, the diaphragm in the cavity bulges and the water can be directly discharged into the water tank through the valve body.
5. When the water level in the water tank is parallel to the water outlet, the diaphragm is sucked tightly due to natural pressure and sticks to the water inlet, so that water cannot enter.
When the water in the sink is lower than the drain pipe again, the diaphragm bulges again and the water enters the sink again.
Six, usually do not need to enter the water type can be adjusted by the switch on the shell, so that the diaphragm is tight.
