The present invention relates to a toilet flushing valve, and more particularly, separate toilet and urine levers are mounted and the amount of wash water can be adjusted according to the toilet and urine functions, respectively, so that water consumption can be saved when urinating. It relates to a water-saving toilet bowl size-differentiated washing valve.

In general, unlike household toilets, toilets equipped with a washing valve directly connected to a 1-inch large-diameter water pipe without a water tank are used by many people in public toilets, public offices, and offices.

Since the amount of water consumed per day of a toilet operated by a washing valve is considerable, a toilet washing valve capable of distinguishing between large and urine is used in order to save such a large amount of water.

In a general toilet and urine distinction type toilet washing valve, when the toilet and urine are operated, the piston in the valve rises to discharge washing water, and after a certain period of time, the piston descends to block the washing water.

In Republic of Korea Patent Registration No. 1196425, "Washing valve for toilet", the large and small operating mechanisms were separately installed, and the amount of water used was divided into two stages by differentiating the height at which the piston rises.
