The present invention relates to a valve for feeding liquid feed, which forms an opening on the outer surface of the valve tube, forms an intermittent jaw that partitions the inner space on the inner circumferential surface, and communicates with the opening on the outer surface of the valve tube, thereby providing air to the upper surface. Install an air valve to be supplied, install an intermittent valve with a rubber pad inside, and when air is injected into the air valve, the rubber pad is pushed in the direction of the intermittent jaw by the air, but the internal space of the valve tube is divided. Closed to the upper surface of the intermittent jaw so as to seal the liquid feed is prevented from moving in the valve tube, the rubber pad is returned to its original position by the elastic force when the air injection is canceled liquid feed grade to allow the liquid feed in the valve tube It is to provide a use valve. According to the present invention, the control valve is automatically operated with a predetermined time difference to supply a predetermined amount of feed to the feed container, and the rubber pad of the control valve is automatically operated by air and then returned to its original position by elastic force to control the control valve. There is no need to operate, especially when the control valve is inoperable due to electrical damage and malfunction, the rubber pad is returned to its original state and the liquid feed is continuously supplied through the valve tube. There is no difficulty in ingestion, and also, in the case of winter, the heat of the heater pad is transferred to the rubber pad, thereby preventing the rubber pad from being cooled.본 발명은 액상사료 급이용 밸브에 관한 것으로, 밸브관의 외면에 개방구를 형성하되, 내주면에 내부공간을 구획하는 단속턱을 형성하며, 밸브관의 외면에 개방구와 연통되되, 상면에 공기를 공급받는 공기밸브를 설치하며, 내측에 고무패드를 형성한 단속밸브를 설치하여, 공기밸브로 공기를 주입하게 되면, 고무패드가 공기에 밀려 단속턱 방향으로 눌림되되, 밸브관의 내부공간이 구획 밀폐되도록 단속턱의 상면에 밀착되어 액상사료가 밸브관 내에서 이동하는 것을 차단하고, 공기 주입 해지시 고무패드가 탄성력에 의해 원위치로 복귀되어 밸브관 내에서 액상사
