[본 발명은 산업통상자원부 한국산업기술진흥원의 혁신도시 공공기관연계 육성사업(공공기관 연계형)의 일환으로 수행한 연구로부터 도출된 것이다: 과제고유번호: P0002065, 연구과제명: 12,000psi급 수소 충전소 제어시스템용 초고압 레귤레이터 개발][The present invention is derived from a study conducted as part of the Innovation City Public Institution Linkage Development Project (public institution linkage type) of the Ministry of Trade, Industry and Energy, Korea Industrial Technology Promotion Agency: Project unique number: P0002065, Research project name: 12,000psi hydrogen Development of ultra-high voltage regulator for charging station control system]
레귤레이터는 배관 라인에 장착되어 유체의 유동을 조절하는 기능을 수행하는 장치로, 주로 유입구를 통해 고압의 유체를 공급받아 일정한 압력으로 감압한 다음 감압된 유체를 배출구를 통해 배출하는 기능을 수행한다.A regulator is a device mounted on a pipe line to control the flow of a fluid, and mainly receives a high-pressure fluid through an inlet, depressurizes it to a constant pressure, and then discharges the depressurized fluid through an outlet.
도 1을 참조하면 배관 라인에 장착되어 유체의 유동을 제어하는데 이용되는 레귤레이터(10)가 예시적으로 도시되어 있다. 도 1에 도시된 바와 같이, 레귤레이터(10)는 몸체를 형성하는 바디부(20) 내에 형성된 유로를 밸브장치(30)를 통해 개폐하면서 유체의 흐름을 제어하도록 작동하게 된다.Referring to FIG. 1 , a regulator 10 mounted on a piping line and used to control the flow of a fluid is illustrated by way of example. As shown in FIG. 1 , the regulator 10 operates to control the flow of fluid while opening and closing the flow path formed in the body portion 20 forming the body through the valve device 30 .
구체적으로, 레귤레이터(10)는 바디부(20)에 유체가 유입되는 유입구(22)와 유체가 배출되는 배출구(24)가 구비되고 유입구(22)와 배출구(24) 사이에 유로(26)가 구비된 구조로 형성되며, 바디부(20)에 형성된 유로(26)에 밸브장치(30)가 장착되어 밸브장치(30)의 작동에 따라 유로(26)를 통해 유동하는 유체의 흐름을 제어하도록 구성된다.Specifically, the regulator 10 is provided with an inlet 22 through which the fluid is introduced and an outlet 24 through which the fluid is discharged to the body 20, and a flow path 26 is provided between the inlet 22 and the outlet 24. It is formed in the provided structure, and the valve device 30 is mounted on the flow path 26 formed in the body 20 to control the flow of the fluid flowing through the flow path 26 according to the operation of the valve device 30 . is composed
한편, 레귤레이터(10)의 밸브장치(30)에는 중심부가 관통된 밸브시트(32)가 구비되며, 밸브시트(32)를 관통해 포핏(34)이 탄성부재(36)에 의해 가압된 상태로 장착되어, 포핏(34)의 이동에 따라 밸브시트(32)의 중심부에 형성된 관통홀이 개폐되면서 유체의 유동이 제어되도록 구성되게 된다.On the other hand, the valve device 30 of the regulator 10 is provided with a valve seat 32 having a central part through it, and the poppet 34 passes through the valve seat 32 in a state in which the poppet 34 is pressed by the elastic member 36 . It is mounted so that the flow of the fluid is controlled while the through hole formed in the center of the valve seat 32 is opened and closed according to the movement of the poppet 34 .
또한, 밸브장치(30)의 일측에는 압력 조절부(40)가 구비되어 밸브장치(30)의 작동을 제어하도록 구성된다. 예컨대, 압력 조절부(40)는 조작레버(42)가 스템 부재(44) 등을 통해 연결되도록 구성되어 조작레버(42)의 작동에 따라 밸브장치(30)에 가압력을 인가하도록 구성될 수 있으며, 조작레버(42)를 일측 방향으로 작동시키면 스템 부재(44)를 통해 밸브장치(30)의 포핏(34)이 가압되어 이동해 밸브시트(32)와 포핏(34) 사이가 개방되면서 유체의 유동이 허용되고, 조작레버(42)를 반대방향으로 작동시키면 포핏(34)이 반대측으로 이동해 밸브시트(32)의 중심부에 형성된 관통홀이 포핏(34)에 의해 폐쇄되면서 유체의 흐름이 폐쇄되도록 작동하게 된다.In addition, one side of the valve device 30 is provided with a pressure adjusting unit 40 is configured to control the operation of the valve device (30). For example, the pressure control unit 40 may be configured such that the operation lever 42 is connected through the stem member 44, etc., and applies a pressing force to the valve device 30 according to the operation of the operation lever 42. , when the operation lever 42 is operated in one direction, the poppet 34 of the valve device 30 is pressed and moved through the stem member 44 to open between the valve seat 32 and the poppet 34 and flow of fluid This is allowed, and when the operation lever 42 is operated in the opposite direction, the poppet 34 moves to the opposite side and the through-hole formed in the center of the valve seat 32 is closed by the poppet 34 and the flow of the fluid is closed. will do
그런데, 이러한 레귤레이터(10)는 포핏(34)이 밸브시트(32)에 접촉된 상태와 이격된 상태 사이에서 반복 작동하는 과정에서 접촉면에 손상이 발생하거나 레귤레이터의 압력 조절 범위를 변경하기 위해 밸브시트(32) 및/또는 포핏(34)의 교체가 요구되는 경우가 있는데, 종래의 레귤레이터(10)는 이러한 경우 포핏(34) 또는 포핏(34)이 장착되는 밸브장치(30)의 전체 교체가 요구되어 레귤레이터의 압력 조절 범위를 변경하거나 레귤레이터를 유지보수하는데 비용이 많이 소요되는 문제가 발생할 수 있다. However, in the process of repeatedly operating the poppet 34 between the state in which the poppet 34 is in contact with the valve seat 32 and the state in which it is spaced apart, the regulator 10 may damage the contact surface or change the pressure control range of the regulator. There are cases where replacement of 32 and/or poppet 34 is required. In the conventional regulator 10, in this case, the entire replacement of the poppet 34 or the valve device 30 to which the poppet 34 is mounted is required. This can cause problems such as changing the pressure regulation range of the regulator or expensive maintenance of the regulator.

본 발명의 일 실시예에 따르면, 센싱 조립체(500)는 수용챔버(240)와 압력 조절부(400)가 장착되는 상부 보어부(270)를 구획하는 기능을 수행할 수 있으며, 다이어프램 조립체 또는 피스톤 조립체 등으로 형성될 수 있다. 예컨대, 도면에 도시된 실시형태의 레귤레이터(100)는 센싱 조립체(500)를 피스톤 부재가 구비되는 피스톤 센싱 조립체 형태로 형성해 레귤레이터가 보다 고압의 환경에서 작동될 수 있도록 구성되어 있다.According to an embodiment of the present invention, the sensing assembly 500 may function to partition the receiving chamber 240 and the upper bore part 270 to which the pressure adjusting part 400 is mounted, and a diaphragm assembly or a piston. It may be formed as an assembly or the like. For example, the regulator 100 of the embodiment shown in the drawings forms the sensing assembly 500 in the form of a piston sensing assembly having a piston member, so that the regulator can be operated in a higher pressure environment.
본 발명의 일 실시예에 따르면, 센싱 조립체(500; 피스톤 센싱 조립체)는 피스톤 하우징(510) 내에 축방향을 따라 연장하여 형성된 보어부에 피스톤 로드(520)가 탄성부재[피스톤 스프링(530)]를 통해 일측으로 가압된 상태로 장착되도록 구성될 수 있으며, 피스톤 플레이트(540) 등의 연결부재를 통해 바디부에 장착되도록 구성될 수 있다. 한편, 피스톤 하우징(510)의 일측면에는 관통구멍이 형성되어 피스톤 하우징(510) 내부의 공간부(보어부)와 바디부에 형성된 수용챔버(240)가 연통되도록 구성될 수 있다.According to an embodiment of the present invention, in the sensing assembly 500 (piston sensing assembly), the piston rod 520 is an elastic member (piston spring 530) in the bore portion formed to extend along the axial direction in the piston housing 510. It may be configured to be mounted in a state pressed to one side through, and may be configured to be mounted on the body portion through a connecting member such as a piston plate 540 . On the other hand, a through hole is formed in one side of the piston housing 510 so that the space (bore) inside the piston housing 510 and the accommodation chamber 240 formed in the body part communicate with each other.
전술한 구조에 의하면, 본 발명의 일 실시예에 따른 레귤레이터(100)는 바디부(200) 내에 구비된 밸브 조립체(300)를 통해 유체의 유동을 조절하도록 구성될 수 있으며, 밸브 조립체(300) 내에서 유체의 유동을 조절하는 포핏 밸브(330)가 복수의 부재[제1 부재(340) 및 제2 부재(350)]가 서로 분리 가능하게 결합되어 형성되며 이들 사이에 밸브시트(320)와 상호작용하는 실링부재(360)가 개재되어 장착되도록 구성됨으로써, 밸브시트(320) 및/또는 이와 상호 작용하는 실링부재(360)에 손상이 발생하거나 레귤레이터의 작동 압력/유량 범위 등을 변경하고자 할 때 포핏 밸브(330) 또는 이를 구비하는 밸브 조립체(300) 전체를 교체할 필요 없이 포핏 밸브(330)의 실링부재(360)만 교체하여 이용할 수 있게 되고, 이로 인해 레귤레이터(100)의 유지보수 비용을 저감하고 레귤레이터(100)를 보다 다양한 유압/유량 조건에서 이용하는 것이 가능해 질 수 있게 된다.According to the above structure, the regulator 100 according to an embodiment of the present invention may be configured to regulate the flow of a fluid through the valve assembly 300 provided in the body portion 200, and the valve assembly 300 A poppet valve 330 for controlling the flow of fluid within is formed by detachably coupling a plurality of members (first member 340 and second member 350) to each other, and a valve seat 320 and By being configured to be mounted with the interacting sealing member 360 interposed therebetween, damage occurs to the valve seat 320 and/or the sealing member 360 interacting therewith, or to change the operating pressure/flow range of the regulator When the poppet valve 330 or the entire valve assembly 300 having the same is replaced, only the sealing member 360 of the poppet valve 330 can be replaced and used, which results in the maintenance cost of the regulator 100 and it becomes possible to use the regulator 100 in more various hydraulic pressure/flow conditions.
예컨대, 밸브시트(320)와 상호 작용하는 실링부재(360)에 마모 등의 손상이 발생한 경우 실링부재(360)만 새로운 부품으로 교체해 이용함으로써 용이하게 레귤레이터(100)를 유지보수할 수 있으며, 서로 다른 경사각의 실링면을 구비하는 실링부재(360)로 실링부재(360)를 교체함으로써 레귤레이터(100)의 작동 압력/유량이나 포핏 밸브(300)의 작동 스트로크 등을 용이하게 조절할 수 있게 된다.For example, when damage such as wear occurs on the sealing member 360 interacting with the valve seat 320, the regulator 100 can be easily maintained by replacing only the sealing member 360 with a new part and using each other. By replacing the sealing member 360 with a sealing member 360 having a sealing surface having a different inclination angle, the operating pressure/flow rate of the regulator 100 or the operating stroke of the poppet valve 300 can be easily adjusted.
