Adjustable quantitative drain valve of toilet stool water tank

Abstract

The invention relates to the field of sanitary baths, in particular to an adjustable quantitative drain valve of a toilet stool water tank, which mainly comprises a drainer, a controller, a water control button and a converter, wherein the drainer is installed on a drain pipe at the bottom of the water tank, the controller is connected with the drainer through a supporting rod, the water control button is installed on a tank cover or a tank wall, and the converter is installed on the supporting rod and abuts against the water control button and a water control frame; and an overflow opening is arranged on an overflow pipe below the controller. The adjustable quantitative drain valve is characterized in that the controller is arranged at the upper end of the supporting rod, a gas outlet valve or the gas outlet valve and a gas inlet valve are arranged at the upper part of the controller, a gas inlet is arranged at the lower part of the controller, a sealing sheet is arranged in the cavity of the controller, and the sealing sheet is fastened at the upper end of the overflow pipe through a fixing cap. The invention has the advantages that the regulation of the drainage amount can be carried out as required and can be instantly finished; water can be quantitatively drained, the quantitative drainage can not be influenced by the water storage capacity of the water tank; and the adjustable quantitative drain valve does not easily leak when turned off, has simple manufacture and is convenient to popularize.

Description

technical field [0001] The invention relates to the field of sanitary ware, in particular to an adjustable quantitative drainage valve for a water tank of a toilet. Background technique [0002] There are multiple types of toilet tank drain valves in the prior art. Commonly used drain valves with one gear for draining and half-rows with two gears for draining water are only suitable for storing toilet tanks with a flushing water capacity. In order to save precious water resources, secondary utilization of domestic waste water will become inevitable. For this reason, a toilet water tank that can store more than one flushing water is needed. This water tank needs a drain valve with adjustable discharge and quantitative drainage. Existing "A kind of toilet water tank adjustable quantitative drainage valve" (Patent No. 2008100612820) patent technology also has problems such as being unable to control the water when the water level of the water tank is too low, and the water at t...
