Abstract

본 발명의 유체 유동 분리기에 관한 것이다. 본 발명에 따르면, 유체가 유입되는 주공급관(31), 주 공급관(31)으로부터 분기된 제1분기관(32), 주 공급관(31)으로부터 분기되어 있으며 설정 압력에 따라 개폐 가능한 제2분기관(33) 및 상기 제2분기관(33)을 개폐하도록 탄성 부재(35)의 탄성력을 받는 피스톤 밸브 수단(34)을 포함하는 유체 유동 분리기에 있어서, 상기 피스톤 밸브 수단(34)이 제2분기관(33)을 폐쇄하고 있는 상태에서 상기 주 공급관(31)내 유체가 피스톤 밸브 수단(34)에 작용하는 단면적은, 상기 피스톤 밸브 수단(34)이 제2분기관(33)을 개방하고 있는 상태에서 유체가 피스톤 밸브수단(34)에 작용하는 단면적보다 작은 것을 특징으로 하는 유체 유동 분리기(30)가 제공된다. 본 발명의 유체 유동 분리기는 유체 유동 라인에 있어 종래 기술과는 달리 고압이 발생될 여지가 없으므로 유동 라인의 구성이 보다 용이해지는 장점이 있다. 또한 유입되는 유체의 압력이 작용하는 피스톤 밸브의 단면적이 밸브 개방시와 폐쇄시에 차이가 있으므로, 이를 조정함으로써 밸브의 개폐시기를 조절할 수 있다.A fluid flow separator of the present invention. According to the present invention, the second branch pipe branched from the main supply pipe 31, the first branch pipe 32 branched from the main supply pipe 31, the main supply pipe 31 into which the fluid is introduced, and which can be opened and closed according to a set pressure (33) and a piston valve means (34) subjected to an elastic force of the elastic member (35) to open and close the second branch pipe (33), wherein the piston valve means (34) is a second component. The cross-sectional area where the fluid in the main supply pipe 31 acts on the piston valve means 34 while the engine 33 is closed is such that the piston valve means 34 opens the second branch pipe 33. A fluid flow separator 30 is provided in which the fluid is smaller than the cross-sectional area acting on the piston valve means 34. The fluid flow separator of the present invention has an advantage in that the configuration of the flow line is easier because there is no room for high pressure unlike the prior art in the fluid flow line. In addition, since the cross-sectional area of the piston valve acting on the pressure of the incoming fluid is different at the time of opening and closing the valve, it is possible to adjust the opening and closing time of the valve by adjusting this.
