Abstract

본 발명은 휴즈밸브 장치(10)에 관한 것이다.The present invention relates to a fuse valve device (10).

유체펌핑 시스템의 펌프(22)의 작동이 정지되면, 수충압으로 인한 유압에 의해 제3플레이트(26b) 및 피스톤(38)이 뒤로 밀리면서 분기 파이프(14)의 단부가 개방되고, 유체는 드레인 박스(16)의 내부로 유동된 후 드레인 파이프(18)를 통하여 방류되거나 또는 취유조로 환원될 수 있게 된다. 피스톤(38)이 뒤로 밀리면 휴즈밸브(50)가 개방되면서 유압 실린더(36)내의 오일이 휴즈 파이프(46)를 통하여 오일탱크(52)로 복귀된다.When the pump 22 of the fluid pumping system is stopped, the end of the branch pipe 14 is opened while the third plate 26b and the piston 38 are pushed back by hydraulic pressure due to water pressure, and the fluid is drained. After flowing into the box 16 it can be discharged through the drain pipe 18 or reduced to the oil sump. When the piston 38 is pushed backward, the fuse valve 50 is opened and oil in the hydraulic cylinder 36 is returned to the oil tank 52 through the fuse pipe 46.

Claims

A fuse valve device for use in a fluid pumping system including a pump for pumping fluid and an oil supply pipe connected to the pump, comprising: a branch pipe having one end connected to the oil supply pipe; A drain box having one end connected to the branch pipe and a drain pipe formed at the other end thereof; A hydraulic cylinder disposed inside the drain box; A piston member provided in the hydraulic cylinder in a reciprocating manner while the rod portion protrudes outward to normally close the other end of the branch pipe; A fuse pipe having one end connected to the hydraulic cylinder; And a fuse valve means disposed in the path of the fuse pipe and normally maintained in the closed position.

The oil tank of claim 1, further comprising: an oil tank connected to the other end of the fuse pipe; And an oil pump for pumping oil in the auxiliary oil tank to the hydraulic cylinder.

The fuse valve device according to claim 1, further comprising a valve means disposed in a path of the branch pipe and normally maintained in an open position.

A plate as claimed in claim 1, further comprising: a plate fixed to the piston rod of the hydraulic cylinder to normally close the other end of the branch pipe; And an elastic member for pulling the plate in a direction in which the other end of the branch pipe is opened.
