Water-saving type water drain valve for water tank

Abstract

The invention relates to a water-saving type water drain valve for a water tank. The structure comprises a water-collecting screw pipe, a double-row-pipe valve body, a two-way valve core and a chain type controller, wherein the water receiving screw pipe is installed on a water drain port of a washing water tank, and the double-row-pipe valve body is connected with the water-collecting screw pipe. The structure comprises a main drain pipe, a water inlet pipe head, a waste water drain pipe, a clean water drain pipe and a valve core shaft cover, and the two-way valve core is installed on the double-row-pipe valve body. The structure comprises a cylinder type valve core and a shaft type valve rod, and the chain type controller is connected with the two-way valve core. The double-row-pipe valve body and the two-way valve core in the embodiment are combined, and water drained by the washing water tank can be conveniently collected into a water storage box for reuse or is directly drained from an original waste water pipe. The chain type controller enables washing personnel to know about the water drain situation at any time, the washing personnel toggles a control handle according to the washing situation, and water in the washing water tank is collected, drained or closed. Therefore, the water-saving type water drain valve for a water tank has reasonable structure and simplicity for control and is convenient for people to save water.

Description

technical field [0001] The invention belongs to a drain valve, in particular to a water-saving sink drain valve for discharging water discharged from a washing tank into a sewage pipe or collecting it into a water storage tank for reuse. Background technique [0002] In order to save water, many people collect and store the relatively clean water used in washing sinks such as laundry sinks, face washing sinks, and vegetable washing sinks into water storage tanks for watering flowers, mopping the floor, and flushing toilets. Work with water that does not require high water quality. In order to conveniently collect the water in the washing sinks such as laundry sinks, face washing sinks, and vegetable washing sinks into the water storage tank, people have designed more styles of sink drain valves. However, these sink drain valves are difficult to install and inconvenient to operate. question. Contents of the invention [0003] In order to solve the problem in the prior art...
