The present invention has a purpose to a dropping button for a watering facility which adjusts the level of opening and closing of a housing depending on the pressure of water or an aqueous solution pumped from a liquid line so as to control and compensate the pressure of the water or the aqueous solution entering the housing, thereby being capable of stably supplying water or an aqueous solution drop by drop from the dropping button at a predetermined speed all the time even if the pressure falls depending on the length of a pipe supplying the water and the aqueous solution. Particularly, the present invention has another purpose to provide a dropping button for a watering facility which precisely adjusts the level of opening and closing of the housing with spring tension using a rod receiving elastic support, thereby preventing the water or the aqueous solution remaining in the housing from flowing backward into the liquid pipe or drainage of residual water, a phenomenon that the water or the aqueous solution is discharged into the outside and drops, even if supply of the water or the aqueous solution stops by a function of the rod as a check valve. In addition, the present invention has the other purpose to provide a dropping button for a watering facility which comprises a dropper body, which forms a channel for the water or the aqueous solution in the housing and elastically supports the rod, to be easily separated/combined from/with the housing, thereby separating the dropper body from the housing and cleaning the channel, and then reassembling the same to reuse even if the dropping button loses functions thereof, for example, clogging of the channel or fertilizer deposition.COPYRIGHT KIPO 2016본 발명은 액관에서 압송하는 물 또는 수액의 압력에 따라 하우징의 여닫는 정도를 조절하여 그 안으로 들어오는 물 또는 수액의 압력을 조절·보상할 수 있게 함으로써, 물이나 수액을 공급하는 파이프의 길이에 따라 압력 강하가 발생하더라도 점적 버튼에서 항상 미리 정한 속도로 한 방울씩 안정적으로 물이나 수액을 제공할 수 있게 한 관수 시설용 점적 버튼을 제공하는 데 그 목적이 있다.특히, 본 발명은 상기 하우징의 여닫는 정도를 탄성 지지를 받는 로드를 이용하여 스프링 장력으로 확실하게
