Description

디스크 플렉시블 메탈시트 버터플라이 밸브{DISC FLEXIBLE METAL SEAT BUTTERFLY VALVE}Disc Flexible Metal Seat Butterfly Valve {DISC FLEXIBLE METAL SEAT BUTTERFLY VALVE}

본 고안은 초고온 및 초저온에 사용되는 디스크 플렉시블 메탈시트 버터플라이 밸브에 관한 것으로서,The present invention relates to a disk flexible metal seat butterfly valve used for ultra high temperature and ultra low temperature,

종래에는 밸브 디스크 및 몸체에 고무 종류의 시트링을 고정하여 사용하므로 인해 고무시트의 부식이 심하였고 이로인해 수명이 짧았으며,Conventionally, rubber seats are fixed to the valve disk and the body so that the rubber seats are severely corroded and thus have a short life.

유체의 온도가 고온이나 저온에는 아예 사용하지도 못하여 외국제품을 전량 수입하여 사용하여야 함으로 인해 납기 및 A/S도 즉시 이루어지지 않는 폐단이 있었으며, 국내에서도 메탈시트 밸브를 제작하고 있으나 시트부분이 유연하게 될 수 있게 재질을 선택하여야 하는 데도 불구하고,There was a closed end where the delivery time and A / S were not made immediately due to importing and using all foreign products because the fluid temperature could not be used at high temperature or low temperature. Despite the choice of materials to be possible,

무작정 디스크시트와 몸체시트를 고정식으로 제작하므로 인해 메탈시트 밸브의 역할을 못하였다.Because the disc seat and body seat were fixed, they did not function as metal seat valves.

본 고안은 상기와 같은 문제점을 해결하기 위하여 디스크(2)원주의 중간부분에 재질이 강하면서 유연성의 탄력을 가진 플렉시블시트(12)를 삽입하고 폐쇄시 원주면의 끝단과 몸체시트(11) 부분과 유체가 흐르지 못하게 강하게 압착되게 한다.In order to solve the above problems, the present invention inserts a flexible sheet 12 having a high elasticity and flexibility in the middle portion of the disk (2) circumference and the end of the circumferential surface and the body sheet (11) when closed. Press firmly to prevent flow of excess fluid.

이때 왼쪽 방향으로 유체가 통과할 시 압력이 높으면 높을수록 플렉시블시트(12)의 원주 부분이 천천히 벌어지면서 더욱 더 압착되어 폐쇄시 유체의 흐름이 전혀없게 하고,At this time, the higher the pressure when the fluid passes in the left direction, the more the circumferential portion of the flexible sheet 12 is slowly opened and more compressed, so that there is no flow of fluid at the time of closing,

플렉시블시트(12)가 놀지 못하게 시트 그랜드(15)를 삽입하고 수개의 렌치볼트(14)로 원주방향으로 고르게 죄어준다.The seat gland 15 is inserted so that the flexible sheet 12 does not play and is evenly tightened circumferentially with several wrench bolts 14.

본 고안은 종전의 고무시트 밸브는 초고온 및 저온에는 사용할 수 없었던 밸브를 초고온 및 초저온에 견딜 수 있게 밸브시트를 흑연메탈(GRAPHITE METAL) 재질로서 유연성이 있는 'L'형의 플렉시블시트(12)를 사용하여 초고온 및 초저온의 관로에 사용할 수 있게 한 것이다.The present invention is a conventional rubber seat valve is a 'L' type flexible seat (12) with flexible flexible seat seat graphite graphite (GRAPHITE METAL) material to withstand the high temperature and low temperature valves that could not be used at very high and low temperatures It can be used for the ultra high temperature and ultra low temperature pipeline.

몸체(1)의 중심부에 메인축(9)을 삽입하고 메인축(9)의 아래 끝단은 디스크(2)의 상부보스(5)를 삽입하고 메인축(9)을 고정하기 위하여 상부핀(7)과 중간핀(8)으로 고정한다.Insert the main shaft (9) in the center of the body (1) and the lower end of the main shaft (9) inserts the upper boss (5) of the disk (2) and the upper pin (7) to fix the main shaft (9) ) And the middle pin (8).

또한, 하부축(10)을 삽입하고 하부축(10)의 상부 끝단은 하부보스(6)에 삽입한 후 하부축(10)을 고정하기 위하여 하부핀(4)으로 고정한다. 하부축(10)의 외주면에는 원활하게 회전을 하기 위하여 하부부싱(17)을 삽입하고 하부축(10)의 아래 끝단에는 스라스트(18)를 삽입하며, 하부축(10)의 처짐을 방지하기 위하여 엔드카바(20)를 장착하고 엔드카바(20)를 고정하기 위하여 수개의 볼트(19)를 체결한다.In addition, the lower shaft 10 is inserted and the upper end of the lower shaft 10 is inserted into the lower boss 6 and then fixed with the lower pin 4 to fix the lower shaft 10. The lower bushing 17 is inserted into the outer circumferential surface of the lower shaft 10 and the thrust 18 is inserted into the lower end of the lower shaft 10 to prevent sagging of the lower shaft 10. In order to mount the end cover 20 and fasten several bolts 19 to fix the end cover 20.

그리고 메인축(9)의 외주면에는 부싱(28)을 삽입하고 부싱(28)의 상단에는 패킹(27)을 삽입하고 그 위에 패킹그랜드(24)를 올려놓고 수개의 롱볼트(23)로 패킹그랜드(24)를 고르게 죄인다.Then, the bushing 28 is inserted into the outer circumferential surface of the main shaft 9, the packing 27 is inserted into the upper end of the bushing 28, the packing grand 24 is placed thereon, and the packing grand is made of several long bolts 23. Sin (24) evenly.

또한, 메인축(9)의 상부축(3)에는 감속기를 삽입할 수 있게 하고 감속내의 기어와 일체가 되게 키(21)를 심는다.In addition, a key 21 is planted in the upper shaft 3 of the main shaft 9 so as to allow the reduction gear to be inserted and to be integral with the gear in the reduction gear.

또한, 몸체시트(11)의 내부면에 원주형의 디스크(2)를 장착하고 디스크 오링(16)을 삽입한 후 디스크(2)의 중심부의 원주면에는 플렉시블시트(12)를 삽입하며 플렉시블시트(12) 상단에는 그랜드 오링(13)을 삽입된 시트 그랜드(15)를 올려놓고 수개의 렌치볼트(14)로서 원주 방향으로 죄임하도록 한 것이다.In addition, a cylindrical disk 2 is mounted on the inner surface of the body sheet 11, a disk o-ring 16 is inserted, and a flexible sheet 12 is inserted into the circumferential surface of the center of the disk 2. (12) On the upper end, the seat gland 15 into which the grand o-ring 13 is inserted is placed and clamped in the circumferential direction as several wrench bolts 14.

이와같이 된 본 고안은This invention made in this way

감속기로서 상부축(3)을 회전시키면 메인축(9)이 회전하여 상부보스(5)와 하부보스(6)로 연결되어 있는 디스크(2)가 약 90도로 좌·우 회전하면서 개폐가 이루어지고 이때 플렉시블시트(12)와 몸체시트(11)가 압착되어 유체가 누유되지 않고, 90도로 열리면 유체가 통과하게 된다.When the upper shaft (3) is rotated as a reducer, the main shaft (9) rotates to open and close the disk (2) connected by the upper boss (5) and the lower boss (6) by rotating the left and right by about 90 degrees. At this time, the flexible sheet 12 and the body sheet 11 are compressed so that the fluid does not leak, and when opened at 90 degrees, the fluid passes.

이와같은 본 고안은 초고온 및 초저온에 견딜 수 있게 흑연메탈재질로서, 유연성이 있는 'L' 형의 플렉시블시트(12)를 사용하여 관로내의 유체의 압력이 높으면 높을수록 플렉시블시트(12)가 벌어지면서 더욱 더 압착되어 누유가 없게 하는 효과가 있다.The present invention is a graphite metal material capable of withstanding ultra-high temperature and cryogenic temperature, using the flexible 'L' type flexible sheet 12 having flexibility, the higher the pressure of the fluid in the pipeline, the more the flexible sheet 12 is opened. Compress more and more has the effect of avoiding leakage.
