본 고안은 고온 고압의 액체나 기체 및 중저압 수증기를 밀폐시키는 버터플라이 밸브의 시트구조에 관한 것으로 특히 본체 내주면 일측에 요입홈을 가진 지지환턱을 형성하여 밀착시트를 끼우고 결착판으로 지지시키되 그 사이의 가압공간부와 밸브원판 내외측이 연통되는 도압구멍을 각각 형성하여 차단된 유체압력이 그 도압구멍에 유입되어 밀착시트를 밸브원판에 가압케 함으로서 유체의 압력이 강할수록 밀폐력이 한층 강화되고 유체의 흐름에 따라 양방향에서 차단하여 밀폐시킬 수 있도록 한 것이다.The present invention relates to a seat structure of a butterfly valve for sealing a high temperature and high pressure liquid or gas and medium and low pressure steam, and in particular, by forming a support ring with a recessed groove on one side of the inner circumferential surface of the main body, inserting a close contact sheet and supporting it with a binding plate. The pressure space between the valve disc and the inner and outer sides of the valve disc is formed, respectively, and the blocked fluid pressure flows into the pressure hole to press the contact sheet against the valve disc. According to the flow of the fluid to be blocked in both directions to be sealed.
종래의 버터 플라이 밸브는 밀착(고무)시트를 밸브원판이 가압하여 고무의 탄력성으로 차단되게한 구성이었기 때문에 강한 압력이 유입되면 밀착력이 떨어지므로 사용유체가 상온 저압에 한하는 결점이 있었다.In the conventional butterfly valve, the contact sheet (rubber) was pressurized by the valve disc to block the elasticity of the rubber. Therefore, when a strong pressure flows, the adhesion decreases, and thus the use fluid is limited to low temperature at room temperature.
또한 회전봉과 지지된 밸브원판도 개폐할때 마다 밀착시트와 접촉되어 마모되기 때문에 밀착력이 떨어지고 높은 유속에서 밀리게 되었으며, 일방향에서 밀폐되게한 것이어서 유체흐름이 변경되면 차단에 많은 어려움이 있었다.In addition, the rotary rod and the support valve disc also come in contact with the contact sheet every time it is opened and closed, and thus the adhesion is reduced and pushed at a high flow rate, and it is closed in one direction, so that there is a lot of difficulty in blocking when the fluid flow is changed.
본 고안은 위와 같은 문제점을 해결하기 위하여 밸브원판에 차단되는 유체의 압력으로 밀착시트를 가압하여 밸브원판을 긴밀히 밀폐하고 양방향에서 차단되게 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is to close the valve disc by tightly sealing the valve disc by the pressure of the fluid blocked on the valve disc in order to solve the above problems and to be blocked in both directions as described in detail by the accompanying drawings as follows.
본체(1) 내측에 밸브원판(2)이 편심되게 장착되어 관로(4)를 개폐하는 것에 있어서, 그 밸브원판(2)의 외주면 전방에 요입홈(6)을 가진 지지환턱(5)을 형성하여 밀착면(11)이 돌설되게 밀착시트(10)을 끼운후 결착판(7)을 고정시키되 밀착시트(10)의 중앙 양단에 가압부(12)(12’)를 형성하고 지지환턱(5)과 결착판(7)일측에는 도압구멍(8)(8’)을 각각 형성하여 밸브원판(2)의 내외측에서 밀착시트(10)의 가압부(12)(12’)상측의 가압공간부(9)(9’)와 연통되게 하고 밀착시트(10)의 중앙일측에는 다수의 금속박판(13)을 적층되게 함장하여서된 것이다.The valve disc 2 is eccentrically mounted inside the main body 1 to open and close the conduit 4 so as to form a support ring 5 having a recess 6 in front of the outer circumferential surface of the valve disc 2. Insert the contact sheet 10 so that the contact surface 11 protrudes, and then fix the binding plate 7 to form press parts 12 and 12 'at both ends of the center of the contact sheet 10 and support support jaw 5 ) And a pressurizing hole 8, 8 ′ are formed at one side of each of the binding plate 7 and the pressurizing space above the pressurizing portion 12, 12 ′ of the contact sheet 10 at the inside and the outside of the valve disc 2. It is made to be in communication with the parts (9) (9 ') and to be laminated to a plurality of metal thin plates 13 on the central side of the contact sheet (10).
도면중 미설명부호 2’는 회전축봉, 3은 조정핸들, 6’는 요입홈, 7a는 결착볼트.In the drawings, reference numeral 2 'is a rotating shaft rod, 3 is an adjusting handle, 6' is a recess groove, 7a is a binding bolt.
이와같이 구성된 본 고안은 통상의 버터플라이밸브에서와 같이 조정핸들(3)을 회전시키면 회전축봉(2’)에 지지된 밸브원판(2)이 관로(4)를 개폐시키게 된다.The present invention configured as described above causes the valve disc 2 supported on the rotating shaft rod 2 'to open and close the conduit 4 when the adjustment handle 3 is rotated as in a conventional butterfly valve.
이때 도면의 제3a도 에서와 같이 유체압력을 밸브원판(2)이 와전히 닫힌 상태에서 관로내의 내측으로 차단시키면 밀폐된 유체압력은 일측의 도압구멍(8)으로 유입되어 가압공간부(9)에 도달하게 되고 그 가압공간부(9) 내의 유체압력은 가압부(12)를 밸브원판(2) 외주면 쪽으로 가압시켜 밀착시트(10)의 밀착면(11)이 밸브원판(2)의 외주면을 긴밀하게 밀폐시키게 된다.At this time, as shown in FIG. 3A of FIG. 3, when the fluid pressure is blocked to the inside of the conduit while the valve disc 2 is completely closed, the sealed fluid pressure flows into the pressure hole 8 on one side to pressurized space 9. And the fluid pressure in the pressurizing space 9 pushes the pressurizing portion 12 toward the outer circumferential surface of the valve disc 2 so that the contact surface 11 of the contact sheet 10 is connected to the outer circumferential surface of the valve disc 2. It is tightly sealed.
또한 도면의 제3b도에서와 같이 유체압력을 밸브원판(2) 외측에서 차단시키면 유체압력은 일측의 도압구멍(8’)을 거쳐서 가압공간부(9’)에 도달함과 동시에 가압부(12’)를 가압시켜 밀착시트(10)의 밀착면(11)이 밸브원판(2)의 외주면을 긴밀하게 밀폐시키게 된다.In addition, as shown in FIG. 3B of the drawing, when the fluid pressure is blocked outside the valve disc 2, the fluid pressure reaches the pressurizing space 9 'through the pressure hole 8' on one side and at the same time the pressurizing part 12 ') By pressing the close contact surface 11 of the contact sheet 10 is to close the outer peripheral surface of the valve disc 2 tightly.
즉, 유체압력을 양방향에서 차단하더라도 밸브원판(2)의 내외측에 형성한 도압구멍(8)(8’)에 의해서 밀착시트(10)의 밀착면(11)이 밸브원판(2)을 긴밀히 밀폐시키게 될뿐만 아니라 밸브원판(2)에 차단된 유체압력이 강할수록 밀착시트(10)가 밸브원판(2)과 강하게 밀착되어 긴밀한 밀폐상태를 유지하게 된다.In other words, even when the fluid pressure is blocked in both directions, the contact surface 11 of the contact sheet 10 closely contacts the valve disk 2 by the pressure holes 8 and 8 'formed in the inner and outer sides of the valve disk 2. In addition to being sealed, the tighter the fluid pressure is blocked to the valve disc 2, the tighter the seat 10 is in close contact with the valve disc 2 to maintain a tightly closed state.
또한 밀착시트(10)중앙에 다수의 겹층으로 함장된 금속박판(13)에 의해서 밀착시트(10)의 변형을 방지하여 준다.In addition, the contact sheet 10 prevents the deformation of the contact sheet 10 by the metal thin plate 13, which is packed in a plurality of layers in the center.
따라서 본 고안은 밸브원판(2)이 유체압력을 차단한 상태에서 밸브원판(2) 외주면과 맞닿은 밀착시트(10)로 밀폐하되 차단된 유체압력으로 밀착시트(10)를 가압하여 밸브원판(2) 외주면에 긴밀히 밀폐시키고 이를 밸브원판(2) 내,외측의 양방향에서 기능을 하게 되므로 고온, 고압의 기체나 액체 및 중저압 수증기등을 한층 효과적으로 개폐할 수 있게 되는 것이다.Therefore, the present invention, while the valve disc 2 closed the fluid pressure, the valve disc 2 is sealed with the contact sheet 10 in contact with the outer circumferential surface of the valve disc 2 but by pressing the contact sheet 10 with the blocked fluid pressure to the valve disc 2 Closely sealed on the outer circumferential surface and functions in both directions inside and outside the valve disc (2), so that high and high pressure gas or liquid and medium and low pressure steam can be opened and closed more effectively.
