Abstract

캡너트를 제거하지 않고 또한 밸브 본체를 코킹하기 위한 공정을 생략한 상태에서 밸브 본체를 조작할 수 있고, 밸브 레버가 튀어나가지 않도록 캡너트를 구성한 공기조화장치용의 보안성이 높은 서비스 밸브가 제공된다. 이 서비스 밸브는 6각 회전용 콘트롤 슬롯(19)이 중심에 형성된 밸브 레버(13) 상부의 외주연(edge)에 테이퍼부(14)가 형성되고, 이 테이퍼부(14)에 대향하여, 상기 밸브 레버(13)가 나사결합되는 밸브 본체의 내주연에 역 테이퍼부(9)가 형성되며, 상기 밸브 본체 상부에 나사결합되는 캡너트(20)의 상벽 중심에 관통공(22)이 형성되고, 상기 상벽의 하면에 형성된 상기 관통공(22)의 외주를 따라, 상기 테이퍼부(14) 및 역 테이퍼부(9) 모두에 접하는 링형 돌기(23)가 형성되어 있다.The valve body can be operated without removing the cap nut and the process for caulking the valve body is omitted, and a highly secure service valve for an air conditioner having a cap nut is provided so that the valve lever does not protrude. do. The service valve has a tapered portion 14 formed at an outer edge of the upper portion of the valve lever 13 having a hexagonal control slot 19 formed thereon, and facing the tapered portion 14, A reverse taper portion 9 is formed at an inner circumference of the valve body to which the valve lever 13 is screwed, and a through hole 22 is formed at the center of the upper wall of the cap nut 20 screwed to the upper portion of the valve body. A ring-shaped protrusion 23 is formed along the outer periphery of the through hole 22 formed on the lower surface of the upper wall, in contact with both the tapered portion 14 and the reverse tapered portion 9.
