Support rotation type automatic cut-off device

Abstract

The invention relates to a water-saving valve, in particular to a support rotation type automatic cut-off device. The device consists of an outlet pipe, two acrodont bars, two overflow valves, an overflow pipe, a valve box, a water inlet hole, two water valves and a floating block. The two water valves for controlling cold water and hot water are positioned on an edge stage in a water pool; and the rectangular box-shaped valve box is fixed on the wall of the water pool between the two water valves. The left inner wall and the right inner wall of the valve box are respectively provided with oneacrodont bar which is successfully matched therewith; and the bottoms of the two acrodont bars are respectively connected with the floating block in the valve box. After passing through the two watervalves, two feed pipes enter the valve box from the back wall of the valve box and join in to be the outlet pipe in the valve box. The two feed pipes which are positioned in the valve box are respectively provided with one overflow valve, the outer parts of the overflow valves are provided with mutually occluded gears, and the two gears are simultaneously, respectively and mutually occluded withthe teeth at the two gears. The device can prevent water waste and accident caused by forgetting to turn off the water tap.

Description

technical field [0001] The invention relates to a water-saving valve, in particular to a rotary automatic flow interceptor. Background technique [0002] Existing water taps usually adopt manual control valve switch. Unscrew the faucet when the water is stopped. It is easy to forget to turn off the faucet when there is no water flowing out. Although the existing pools usually have overflows, the flow rate of the water flowing away through the overflows is determined by the water in the pool. The height of the water surface beyond the overflow is determined, and the water flowing from the faucet is sprayed under the action of the water supply pressure in the water supply pipe, so the drainage speed of the overflow port is usually lower than the water supply speed of the faucet, which will cause water in the sink. The overflow of water not only wastes a lot of water resources, but also easily causes safety accidents. Contents of the invention [0003] In order to solve the...
