Abstract

본 발명은 액츄에이터로 연결되는 유출구를 신속하게 닫아주므로 정밀한 작동이 되도록 하기 위해, 내에 실린더가 형성되고, 펌프에 연결되는 유입구와 액츄에이터에 연결되는 유출구가 중간 외주면에 일정 간격을 두고 형성되며, 상기 실린더 일축이 파일럿밸브에 연통되게 연결되는 밸브몸체와; 상기 밸브몸체의 실린더에 슬라이딩 가능하게 삽입되어 일단부에 복귀스프링이 탄지되고, 중간부 외주면의 외경이 축소되어 상기 유입구와 유출구 사이에 작동공간을 형성하며, 타단부에 피스톤이 장착되는 스풀실린더가 형성되고, 중간부 외주면에 오일구멍이 스풀실린더에 연통되게 형성되는 스풀로 구성되어, 스풀이 복귀될 때 복귀스프링의 탄발력에 오일구멍을 통해 타단부에 작용하도록 유압을 추가시켜 신속하게 유출구를 차단하도록 하는 급속 차단용 유압밸브이다.The present invention is to close the outlet connected to the actuator quickly so that the precise operation, the cylinder is formed, the inlet connected to the pump and the outlet connected to the actuator is formed at regular intervals on the intermediate outer peripheral surface, the cylinder A valve body having one shaft connected in communication with the pilot valve; The spool cylinder is slidably inserted into the cylinder of the valve body and the return spring is held at one end, and the outer diameter of the outer peripheral surface of the middle part is reduced to form an operating space between the inlet and the outlet, and the piston is mounted at the other end. It consists of a spool which is formed on the outer peripheral surface of the intermediate part in communication with the spool cylinder, and when the spool returns, it adds hydraulic pressure to act on the other end through the oil hole to the elastic force of the return spring to quickly discharge the outlet. Hydraulic shut-off valve to shut off.
