Description

이엽밸브디스크의 제수밸브{Double disc gate valves}Double disc gate valves

본 고안은 제수밸브가 안고 있는 부식 및 동파 등의 단점을 보완하고 외력이나 내압, 온도 등의 변화에 의한 밸브 몸체의 변화에도 자기보정되는 이엽형태의 스테인레스 디스크 구조로 하고 디스크 둘레가 칼날 형상을 갖게 하여 밸브하부 요홈에 누적되는 슬러지 및 기타오물 등을 절단하며 닫혀지게 하여 완벽한 누수차단을 할 수 있게 한 이엽밸브 디스크의 제수밸브에 관한 것이다.The present design compensates for the shortcomings of corrosion and freeze, etc. that the dividing valve has, and has a double-leaf stainless disk structure that self-corrects against changes in the valve body due to changes in external force, internal pressure, temperature, etc. The present invention relates to a dividing valve of a double-leaf valve disc that is closed by cutting and closing sludge and other dirt accumulated in the lower groove of the valve.

종래 제수밸브는 밸브본체 내부에 디스크 작동을 원활하게 이루어지도록 요홈부가 형성되어 있어 이 요홈내에 이물질인 슬러지 및 기타 오물등이 누적되어 디스크의 개폐를 방해하며 밸브 본체 시이트와 디스크 시이트의 밀착상태가 좋지 못하여 완전한 기밀을 유지하지 못하고 좁은 틈새를 남기게 됨으로 유체의 케비테이션현상으로 시트면이 단시간에 손상되어 수밀성이 불량하였으며 또한 외력이나 내압, 온도 등의 변화에 의한 몸통의 변화로 밸브본체 시이트의 쐐기각이 변하게 되고 이 변형된 본체시이트의 쐐기각과 변하지 않은 디스크시트의 쐐기각의 미소한 차이로 틈새가 생기므로 유체의 케비테이션현상이 발생하여 시이트면이 손상되어 수밀성이 떨어졌고 밸브 재질이 주철 및 닥타일제로되어 있어 부식 및 동파되는등 여러 문제점이 야기되었던 것이다.Conventionally, the distillation valve has a recessed portion formed to smoothly operate the disk in the valve body, and thus, sludge and other dirt accumulated in the recessed groove prevent the opening and closing of the disk, and the valve body sheet and the disk sheet are in close contact with each other. It is not able to maintain complete airtightness and leaves a narrow gap, so the cavitation phenomenon of the fluid damages the seat surface in a short time, resulting in poor watertightness. The gap between the wedge angle of the deformed body sheet and the wedge angle of the unchanged disc sheet creates a gap, which causes cavitation of the fluid, which damages the sheet surface and degrades the watertightness. Due to the Doctile agent, various problems such as corrosion and freezing were caused.

본 고안은 상기한 바와 같은 문제점을 시정하고자 제안된 것으로서, 슬러지 및 기타 오물 등을 절단하여 닫히게 하기 위해 디스크 둘레를 날카로운 칼날형상의 구조로 하고, 외력이나 내압, 온도 등의 변화에 의한 몸통의 변화에도 사이에 지지대를 갖는 이엽의 디스크 구조로 지지대와 디스크간의 유연성으로 디스크 쐐기각이 자기보정되게 하여 완벽한 수밀성을 갖게 하기 위한 것이다.The present invention has been proposed to correct the problems described above, and the structure of the sharp blade around the disk to cut and close the sludge and other dirt, etc., the change of the body by the change of external force, internal pressure, temperature, etc. It is a double-leaf disc structure having a support between Edo, and the disc wedge angle is self-compensated by the flexibility between the support and the disc to achieve perfect water tightness.

이하, 본 고안의 요지를 첨부도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, the gist of the present invention will be described in detail with reference to the accompanying drawings.

밸브본체(1)의 일측에 후랜지(2)를 가진 유입구(3)를 타측에도 후랜지(4)를 가진 유출구(5)를 형성하고, 중앙부에는 덮개판(6)이 개착되도록 후랜지(7)를 가진 축수구(8)를 형성하며 덮개판(6)의 상면에 상재되는 소켓(9)을 관통시킨 승강봉(10)하단의 나선부(11)에 넛트체(12)가 나합된 제수밸브에 있어서,An inlet 3 having a flange 2 is formed at one side of the valve body 1, and an outlet 5 having a flange 4 is formed at the other side, and a flange is installed at the center to attach the cover plate 6. The nut body 12 is screwed into the spiral portion 11 at the lower end of the elevating rod 10 through which the shaft 9 having the 7) and the socket 9 interposed on the upper surface of the cover plate 6 is formed. In the dividing valve,

밸브디스크(13)(13')를 이엽의 원판으로 구성하여 그 중앙에 지지대(14) (14')로서 서로 지지되게 하며 그 중앙상단에 넛트체(12)를 잡아주는 고정편(15)(15')을 구성하고, 밸브디스크(13)(13')의 원주둘레에 칼날부(16)(16')를 형성한 것이다.Fixing piece 15 which constitutes the valve disc 13, 13 'by the disk of a bileaf | leaf, and is supported by each other as the support stand 14 (14') in the center, and hold | maintains the nut body 12 in the center upper part ( 15 '), and the blade parts 16 and 16' are formed in the circumference | surroundings of the valve disc 13 and 13 '.

미설명부호 17은 요홈부이다Unexplained symbol 17 is a recess

이와 같은 본 고안의 작용을 상세히 설명하면 다음과 같다.Referring to the operation of the present invention in detail as follows.

본 고안의 제수밸브는 그 주요부를 스테인레스로 제작하여 부식 및 녹발생이 없어 위생적이고 온도 및 외력의 변화에도 높은 강도와 유연한 강성을 가지고 있는 것이다.The distillation valve of the present invention is made of stainless steel and its main part is free from corrosion and rust so that it is hygienic and has high strength and flexible rigidity even with changes in temperature and external force.

본 고안의 작동상태를 설명하면 밸브본체(1)의 승강봉(10)을 좌회전시키면 밸브디스크(13)(13')가 상승되어 개방되고 우회전시키면 밸브디스크(13)(13')가 하강되어 폐쇄되는 것으로서, 폐쇄시 밸브본체(1)의 요홈부(17)에 적층되어 있는 이물질인 슬러지 및 기타 오물 등에 의해 밸브디스크(13)(13')의 전폐가 불가능하게 되어도 밸브디스크(13)(13') 주면에 형성되어 있는 칼날부(16)(16')에 의해 이러한 슬러지 및 기타 오물 등을 절단하며 닫혀지기 때문에 요홈부(17)에 이물질이 있어도 방해받지 않고 완전하게 닫히는 것이다.When the operation state of the present invention is described, when the lifting rod 10 of the valve body 1 is rotated to the left, the valve discs 13 and 13 'are raised and opened, and when the right side is turned, the valve discs 13 and 13' are lowered. In the case of closing, the valve disc 13 (13 ') is prevented even when the valve disc 13, 13' is not completely closed due to sludge and other debris, which is accumulated in the recess 17 of the valve body 1 when closing. 13 ') Since the sludge and other dirts are closed by the blade parts 16 and 16' formed on the main surface, the foreign material is completely closed without being disturbed even if there is a foreign material in the recess 17.

또한 도3의 도시와 같이 외력이나 내압의 변화 또는 가공상의 오차 온도차이에 따른 열응력 및 처짐으로 인한 굽힘모멘트등에 의한 변형으로 밸브시이트의 쐐기각이 변형되어도 본 고안의 밸브디스크(13)(13')는 그 중앙에 지지대(14)(14')로서 양 밸브디스크(13)(13')를 지지하게한 이엽의 구조로 지지대(14)(14')와 밸브디스크(13)(13')간에 탄성 및 유연성을 갖는 것으로 밸브본체(1) 시이트 쐐기각에 대하여 디스크쐐기각이 자기 보정이 가능하게 구성한 것으로, 즉, 밸브본체(1) 시이트를 따라 밸브디스크(13)(13')가 닫히면서 밸브본체(1) 시이트의 쐐기각이 변형되어도 지지대(14)(14')와 밸브디스크(13)(13')간의 탄성 및 유연성으로 밸브본체(1) 사이트에 의해 밸브디스크(13) (13')가 지지대(14)(14')를 중심으로 안쪽, 바깥쪽으로 밸브디스크(13)(13')시이트 쐐기각을 변화시키므로 밸브본체(1)시이트 쐐기각에 맞게 변형되어, 밸브본체(1) 시이트에 밀착되어 닫히므로 밸브디스크(13)(13')가 밸브본체(1)에 완전히 밀착되어 완벽한 수밀성을 유지하게 되는 것이다.In addition, as shown in FIG. 3, even when the wedge angle of the valve seat is deformed due to deformation due to a change in external force, internal pressure, or a thermal stress and deflection due to a temperature difference in processing, the valve disc 13 (13) of the present invention. ') Is a double-leafed structure that supports both valve disks 13 and 13' as supports 14 and 14 'at the center thereof, and supports 14 and 14' and valve disks 13 and 13 '. Elasticity and flexibility between the disc body 1 and the disc body wedge angle so that the disc wedge angle can be self-calibrated, that is, the valve discs 13 and 13 ' Even if the wedge angle of the valve body (1) sheet is closed while being closed, the valve disc (13) is opened by the valve body (1) site due to the elasticity and flexibility between the supports (14) (14 ') and the valve disc (13) (13'). (13 ') inside and outside the support (14) (14') By changing the valve disc 13, 13 'sheet wedge angle, the valve disc 13 and 13' are deformed to fit the valve body 1 sheet wedge angle and close to the valve body 1 sheet to close the valve disc 13, 13 '. It is in close contact with the valve body 1 to maintain perfect watertightness.

이상과 같이 본 고안은 밸브의 주요부를 스테인레스로 제작하고 밸브디스크를 이엽으로하여 그 사이 지지대와 탄성을 갖는 유연한 구조로 형성하고 밸브디스크 주연에 칼날부를 형성한 것으로서, 부식 및 녹발생이 없어 위생적이고 온도 및 외력의 변화에도 높은 강도와 유연한 강성을 가지며 외력이나 내압의 변화, 가공상의 오차에 의한 몸통 쐐기각 변화에도 디스크 쐐기각이 자기보정되어 완벽한 누수차단을 하고 슬러지 및 기타 오물 등을 절단하여 닫히게 되므로 밸브의 완전한 전폐가 가능한 유용한 고안인 것이다.As described above, the present invention is made of the main part of the valve made of stainless steel, the valve disk is made of two leaves, and the flexible structure having the support and elasticity therebetween, and the blade portion formed on the periphery of the valve disk, hygienic High strength and flexible stiffness even with changes of temperature and external force, disc wedge angle is self-corrected even if the body wedge angle is changed due to external force, internal pressure change, or processing error, and it closes leak by cutting sludge and other dirt. Therefore, it is a useful design that can be fully closed of the valve.
