[해결하려는 기술적 과제][Technical challenge to solve]

종래의 공지된 밸브구조는 축의 돌편이 개폐판의 돌기를 일측으로 회전하면서 가압하게 되므로 회전되는 방향의 탄성재링은 가압력이 작용하여 통구의 경사원주면에 밀착되는 반면에 반대편의 탄성재링은 가압력이 보다 적게 작용하여 긴밀하게 경사원주면에 밀착되지 아니하므로 오일유통시 이부분을 통해 누유현상이 발생되고 조립시나 운반취급시에도 누유되어 경제적 손실을 감수해야되는등 여러가지의 폐단이 있었다.Conventional well-known valve structure is because the protrusion of the shaft is pressed while rotating the protrusion of the opening and closing plate to one side, the elastic material ring in the direction of rotation is pressed against the inclined circumferential surface of the cylinder while the opposite elastic material ring is pressed There is a lot of discontinuities such as oil leakage phenomenon through this part during oil distribution and oil loss during assembly or conveyance handling.

본고안은 대형변압기와 방열기의 연결후렌지 내부에 설치되는 변압기용 밸브에 관한 것으로 개폐디스크의 밀폐를 정확하게 하여 누유현상을 방지하고자한데 그 목적이 있다.This paper relates to a valve for a transformer installed inside a flange of a large transformer and a radiator. The purpose of the present invention is to prevent leakage by precisely sealing an open / close disk.

종래 공고된 실용신안 공고번호 제87-3182호 변압기용 밸브는 후렌지의 통구를 개폐하는 개폐판의 원주면에 탄성재링을 삽착하고 개폐판에 연결한 축에 개폐판의 돌기에 대응하는 돌편을 돌설하여 통구의 차단시 축이 회전되면서 돌편이 개폐판의 돌기를 밀어 개폐판의 탄성재링이 통구의 경사원주면에 밀착되도록 하므로서 오일의 흐름을 차단하는 구조로 되어 있다.Conventional Utility Model Publication No. 87-3182 for valves for transformers inserts an elastic material ring on the circumferential surface of the opening and closing plate for opening and closing the hole of Hurenji, and protrudes a protrusion corresponding to the projection of the opening and closing plate on the shaft connected to the opening and closing plate. As the shaft is rotated when the cylinder is blocked, the stone piece pushes the protrusion of the opening and closing plate so that the elastic material ring of the opening and closing plate is in close contact with the inclined circumferential surface of the opening, thereby blocking the flow of oil.

그러나, 상술한 밸브구조는 축의 돌편이 개폐판의 돌기를 일측으로 회전하면서 가압하게 되므로 회전되는 방향의 탄성재링은 가압력이 작용하여 통구의 경사원주면에 밀착되는 반면에 반대편의 탄성재링은 가압력이 보다 적게 작용하여 긴밀하게 경사원주면에 밀착되지 아니하므로 오일유통시 이부분을 통해 누유현상이 발생되고 조립시나 운반취급시에도 누유되어 경제적 손실을 감수해야되는등 여러가지의 폐단이 있었다.However, in the valve structure described above, the shaft piece is pressurized while the protrusion of the opening and closing plate is rotated to one side, so that the elastic material ring in the rotating direction is pressed against the inclined circumferential surface of the hole while the elastic material ring on the opposite side has a pressing force. There is a lot of discontinuities such as oil leakage phenomenon through this part during oil distribution and oil loss during assembly or conveyance handling.

[고안이 이루고자 하는 기술적 과제][Technical Challenges to be Done]

본고안은 이와같은 점을 감안하여 개폐판의 원주면을 구면으로 구성하되 개폐판의 구면이 접촉하는 통구의 원주면에 개폐판의 원주면에 대응하는 구면을 형성한 테프론 패킹링을 설치하므로서 누유현상을 확실히 방지할 수 있게한데 있는 것으로 이를 첨부도면에 의거 상술하면 다음과 같다.In view of this, this paper consists of a spherical surface of the opening and closing plate, but by installing a teflon packing ring in which the spherical surface corresponding to the circumferential surface of the opening and closing plate is installed on the circumferential surface of the opening where the sphere of the opening and closing plate contacts It is possible to surely prevent the phenomenon as described in detail according to the accompanying drawings as follows.

[고안의 구성][Composition of design]

변압기(1)와 방열기(2)의 연결후렌지(3)의 내부에 회전축(4)으로 회전작동되는 개폐판(5)을 설치함에 있어서 개폐판(5)의 원주면을 구면(a)으로 형성하고 구면(a)이 접촉하는 연결후렌지(3)의 통구(6) 내주면에 개폐판(5)의 구면(a)에 대응하는 접촉구면(b)을 형성한 한쌍의 테프론 패킹링(7)(7')을 고정링(8)으로 고정 설치하여서 되는 것이다.The circumferential surface of the opening and closing plate 5 is formed as a spherical surface a in the installation of the opening and closing plate 5 which is rotated by the rotating shaft 4 inside the flange 3 of the transformer 1 and the radiator 2. And a pair of Teflon packing rings (7) having a contact hole (b) corresponding to the sphere (a) of the opening and closing plate (5) on the inner circumferential surface (6) of the connecting flange (3) in contact with the sphere (a). 7 ') is to be fixed by the fixing ring (8).

[고안의 작용][Operation of design]

이와같이된 본고안은 전술한 바와같이 변압기(1)와 방열기(2)의 연결후렌지(3)의 내부에 설치되어 개폐판(5)의 개폐작동으로 오일의 흐름을 유통시키거나 차단시키는 작용을 하게 되는 것으로 회전축(4)에 축착된 개폐판(5)의 원주면을 구면(a)으로 형성하고 구면(a)이 접촉하는 후렌지(3)의 통구(6)내주면에는 개폐판(5)의 구면(a)에 대응하는 접촉구면(b)을 형성한 한쌍의 테프론 패킹링(7)(7')을 고정링(8)으로 설치하여서 되는 것이므로 회전축(4)을 작동시켜 개폐판(9)을 회전시키면 원주면의 구면(a)이 테프론 패킹링(7)(7')의 구면(b)과 접촉되면서 개폐되는 과정에서 구면(a)과 구면(b)의 접촉으로 마치 볼의 접촉과 같이 완전 밀착되면서 개폐되는 바, 개폐판(5)의 차단시에는 제2도의 실선과 같이 개폐판(5)의 구면(a)이 고정링(8)으로 튼튼히 고정된 테프론 패킹링(7)(7')의 구면(b)에 완전 밀착되도록 회전시키면 긴밀한 밀폐로서 오일의 누설을 확실히 차단할 수 있게 되는 것이다.As described above, the present proposal is installed inside the connecting flange 3 of the transformer 1 and the radiator 2 so as to circulate or block the flow of oil by the opening and closing operation of the opening and closing plate 5. The spherical surface of the opening and closing plate 5 is formed on the inner circumferential surface of the vent hole 3 of the flange 3 to which the circumferential surface of the opening and closing plate 5 condensed on the rotary shaft 4 is formed as a spherical surface a. Since a pair of Teflon packing rings (7) (7 ') having a contact hole (b) corresponding to (a) is provided by the fixing ring (8), the opening and closing plate (9) is operated by operating the rotating shaft (4). When rotated, the spherical surface (a) of the circumferential surface is in contact with the spherical surface (b) of the Teflon packing ring (7) (7 ') and is opened and closed. Teflon packing ring in which the spherical surface (a) of the opening and closing plate (5) is firmly fixed with the fixing ring (8) as shown in the solid line of FIG. Rotation so as to be in close contact with the spherical surface (b) of (7) and (7 ') makes it possible to close the oil leakage securely as a tight seal.

특히, 본고안은 중심에 축착된 회전축(4)을 회전시키면 원주면의 구면(a)이 균등한 압력으로 테프론 패킹링(7)(7')의 접촉구면(b)에 접촉되어 밀착되므로 전체원주면의 기밀이 일정하여 부분적인 누유현상이 완전히 방지된다.Particularly, in this case, when the rotating shaft 4 condensed at the center is rotated, the spherical surface a of the circumferential surface is brought into close contact with the contact surface b of the Teflon packing ring 7 and 7 'at an equal pressure. The confidentiality of the circumferential surface is constant to prevent partial leakage.

[고안의 효과][Effect of design]

이와같이 본고안은 개폐판(5)의 밀폐를 확실히 하므로서 오일의 누설이 전혀 발생치 않아 조립작업시나 운반시 누유되는 것을 방지하고 이로인해 경제적 손실을 해소할 수 있는 효과가 있다.In this way, since the seal of the opening and closing plate (5) is secured, there is no leakage of oil at all, thereby preventing leakage during assembly work or transportation, and thereby reducing the economic loss.
