Pressure-compensated proportional flow control valve
The present invention relates to a flow control valve used in a flow control system and, more specifically, to a pressure compensated proportional flow control valve including a pressure compensated valve capable of regularly controlling flow at all times regardless of load pressure of a hydraulic motor. Provided is the pressure compensated proportional flow control valve, comprising: a fluid supply unit; a fluid line having an upstream side connected to fluid supply means and a downstream side receiving the fluid; a load connected to the downstream side of the fluid line and actuated by the fluid supplied by the fluid supply unit; a flow control valve controlling the flow of the fluid supplied to the load or blocking the fluid; the pressure compensated valve controlling an opening degree through a piston reciprocating within a cylinder according to the pressure of the load to control the flow of the fluid supplied to the flow control valve; a first return line having an upstream side communicating between the flow control valve and the pressure compensated valve on the fluid line and having a downstream side communicating with one side of the pressure compensated valve to reduce the opening degree of the pressure compensated valve by moving the piston to the other side; and a second return line having an upstream side communicating between the flow control valve and the load on the fluid line and having a downstream side communicating with the other side of the pressure compensated valve to increase the opening degree of the pressure compensated valve by moving the piston to the one side.
본 발명은 유량제어 시스템에 사용되는 유량제어 밸브에 관한 것으로, 더욱 상세하게는 유압모터의 부하압력에 관계없이 항상 일정한 유량제어가 가능한 압력보상형 밸브를 포함하는 압력보상형 비례 유량제어 밸브에 관한 것이다.
