Full-drainage and half-drainage water replenishing control device and drainage valve

Abstract

The invention discloses a full-drainage and half-drainage water replenishing control device which comprises a switching mechanism, an adjusting mechanism and a pipeline mechanism, a drainage valve is provided with a button seat, an overflow pipe, a full-drainage button and a half-drainage button, a mounting cavity is formed in the button seat, the switching mechanism and the adjusting mechanism are both integrated and arranged in the mounting cavity, and the pipeline mechanism is arranged in the mounting cavity. The switching mechanism comprises a rotary switching part, the rotary switching part can be independently communicated with the full-discharge water pipe or the half-discharge water pipe during rotation, and the adjusting mechanism comprises a full-discharge adjusting knob and a half-discharge adjusting knob which are used for adjusting the water replenishing flow. The invention further discloses a drainage valve which comprises the full-drainage and half-drainage water supplementing control device. The water supplementing device can be arranged in the drainage valve, space is saved, the water supplementing flow can be directly adjusted on the drainage valve, and use is convenient; in addition, the water replenishing starting driving force is small, and the good operation hand feeling is achieved.

Description

technical field [0001] The invention relates to the technical field of water replenishment, in particular to a full-half drain water replenishment control device and a drain valve. Background technique [0002] Siphon toilets generally need to replenish water after draining, so that the water seal of the toilet reaches the required water level, isolates the sewage pipeline from the indoor environment, and prevents the gas from the sewage pipeline system from entering the room to cause pollution. In order to replenish water in time, a special replenishment control device is generally installed in the water system. Existing full-and-half-row replenishment control devices are usually set externally, as shown in patent CN203256867U, the device is installed on the overflow pipe of the drain valve in the water tank, and relies on the rise and fall of the water level in the water tank to control the lifting of the floating bucket, and the floating bucket Lifting can drive the forc...

Problems solved by technology

This solution is simple in principle, but has the following disadvantages: since the structure of the water supply control device protrudes from the body of the drain valve, it occupies a large volume, which reduces the adaptability to various sizes of water tanks, and when adjusting the water flow, it is necessary to The valve body of the drain valve can only be adjusted after dismantling it, which is very inconvenient

There is also a drain valve with a water replenisher integrated on the outer side of the button seat. The force of the valve body controlled by the water replenishment increases the driving force of the button to start the drain valve, and the use feeling is poor.
