Abstract

본 발명은 정유량 역지밸브(constant-flow check valve)에 관한 것으로, 특히 유량 및 유압제어 기능이 정확하고 분해결합이 용이하며 유량의 입, 출구 방향을 자유로이 설정할 수 있는 밸브에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a constant flow check valve, and more particularly, to a valve capable of precisely combining flow rate and hydraulic control functions, easily disassembling and combining flow inlet and outlet directions.

일반적으로 고층지대와 저층지대에 급수를 행함에 있어 나타나는 수압차를 해소하기 위하여 유량과 그 압력이 자동조절되는 역지밸브를 설치사용하고 있으나, 유량, 수압이 항시 일정하지 못하고 미세조정이 용이하지 못하였는바 본 발명에서는 밸브몸체(2)에 게이트(7a)가 형성된 가이드 슬리브(7)를 설치하고 이 가이드 슬리브내에 게이트를 개폐하는 고무개폐판(9)과, 게이트로부터의 유체를 통과시키는 오피리스(11b)를 갖는 밸브가드(11)와 게이트(8b)가 형성된 안내구(8)와, 안내구 및 밸브가이드 사이에 개재되는 역지스프링(12)을 설치하면서, 안내구의 외측 오리피스(8a)를 통하여 유체가 배출되게 하였다.Generally, a check valve is installed to automatically adjust the flow rate and its pressure in order to solve the water pressure difference that occurs in water supply in the high and low zones. In the present invention, the valve body (2) is provided with a guide sleeve (7) having a gate (7a) formed in the rubber opening and closing plate (9) for opening and closing the gate in the guide sleeve, and the opiris to pass the fluid from the gate The outer orifice 8a of the guide is provided while providing a guide 8 with a valve guard 11 and a gate 8b having a 11b and a check spring 12 interposed between the guide and the valve guide. Fluid was allowed to flow through.

또 밸브몸체상에 캡을 설치하고 캡에 조정보울트(19)에 의해 이동가능한 슬라이더(16)를 결합하면서 슬라이더와 상기 밸브가드 및 고무개폐관을 스템으로 연결하고 슬라이더와 밸브가드 사이에는 조정스프링을 개재설치한 것이다.In addition, by installing a cap on the valve body and coupling the slider 16 movable by the adjusting bolt 19 to the cap, the slider and the valve guard and the rubber opening and closing tube are connected by a stem, and an adjustment spring is provided between the slider and the valve guard. It was installed intervening.
