Description

technical field [0001] The invention relates to a gate valve, in particular to a mechanical automatic water-cutting gate valve. Background technique [0002] At present, the common automatic water cut-off devices in our daily life mainly include the float water cut-off valve in the sensor faucet and the flush toilet. The induction faucet is composed of a solenoid valve, a controller for opening and closing the solenoid valve by infrared detection, and a water control device for controlling the opening and closing of the solenoid valve at the water inlet and outlet of the faucet. It uses the principle of infrared light reflection. Put your hand under the faucet, the infrared light emitted by the infrared emitting tube is reflected to the infrared receiving tube by the hand, and then the signal is processed to control the solenoid valve to open the water. When the hand leaves the faucet, the infrared light is no longer reflected, and then the solenoid valve is automatically ...
