플랜지형 고성능 버터플라이밸브{HIGH PERFORMANCE BUTTERFLY VALVE OF A FLANGE TYPE}Flanged Type High Performance Butterfly Valve {HIGH PERFORMANCE BUTTERFLY VALVE OF A FLANGE TYPE}

본 고안은 플랜지형 고성능 버터플라이밸브에 관한 것으로, 보다 상세하게는 시트가 3단으로 구성될 뿐만 아니라, 편심되게 형성된 디스크의 외측둘레에 경사부가 형성되어 유체통로에 구성된 돌출턱에 완전히 밀착밀폐되기 때문에 고온고압에서의 고기밀성이 유지되는 장점이 있으며, 시트 마찰에 의한 마모가 억제는 물론, 부드러운 작동에 의해 내구성이 향상되는 장점이 있고, 밸브몸체의 양측에 구성된 연결플랜지에 의해 본 고안과 배관의 연결을 유격없이 이룰 수 있기 때문에 밸브의 견고한 설치를 용이하게 이룰 수 있는 플랜지형 고성능 버터플라이밸브에 관한 것이다.The present invention relates to a flange-type high-performance butterfly valve, more specifically, the seat is composed of three stages, as well as the inclined portion is formed on the outer periphery of the disk eccentrically formed to be completely in close contact with the protruding jaw formed in the fluid passage Because of this, there is an advantage of maintaining high airtightness at high temperature and high pressure, and abrasion by seat friction, as well as the advantage of improving durability by smooth operation, and the present design and piping by connecting flanges formed on both sides of the valve body. This invention relates to a flanged high performance butterfly valve that can facilitate the installation of the valve because the connection of the valve can be made without any play.

일반적으로 종래의 버터플라이 밸브는 밸브시트(200)인 원판시일이 고무, 테프론수지, 이와 유사한 탄성재료로 되어 밸브본체(100)의 내부의 유체통로(110)에 조립된 상태에서 그 외부에 나사 조립되는 원판 커버링(300)에 의하여 지지되어 고정 설치되며, 상기 시트(200)의 내벽에는 개폐디스트(400)가 회전축(410)에 의하여 회전 가능하게 조립되도록 되어 있다.In general, the butterfly valve of the valve seat 200, the disk seal is made of rubber, Teflon resin, a similar elastic material and screwed to the outside in a state assembled in the fluid passage 110 inside the valve body 100 It is supported and fixed by the disk covering 300 to be assembled, the inner wall of the sheet 200 is to be rotatably assembled by the rotation shaft 410 by the rotation shaft 410.

또한, 상기 회전축(410)의 한쪽 단부는 밸브본체(100)의 보스(120)에 지지되고 다른 단부는 밸브본체(400)로부터 연자된 목(neck)(130)을 관통하는 구멍(140)을 통해 연장되며 상기 연장된 회전축(410)에 액추에이터(actuator)을 연결하여 상기 엑추에이터의 작동에 의하여 상기 개폐디스크(400)은 외면(401)이 상기 시트(200)의 내벽에서 이탈 또는 밀착으로 상기 유체통로(110)를 개방 또는 폐쇄하도록 되어 있다.In addition, one end of the rotation shaft 410 is supported by the boss 120 of the valve body 100 and the other end of the hole 140 penetrating through the neck (130) is drawn from the valve body 400 It is extended through the actuator (actuator) connected to the extended rotating shaft 410 by the operation of the actuator, the opening and closing disk 400 is the outer surface 401 of the fluid from the inner wall of the seat 200 is separated or in close contact with the fluid The passage 110 is adapted to open or close.

그러나, 이러한 종래의 버터플라이 밸브에 있어, 상기 개폐디스크(400)는 시트(200)의 내벽(201)에서 상기 회전축(410)의 축선방향(Y)을 기준으로 하여 직교의 횡방향으로 회전하기 때문에 상기 개폐디스크(400)는 중심점(0)과 상기 회전축(410)의 축선방향(Y)과 회전직교선(X) 방향인 양방의 외면점(T) 부분에서 상기 시트(200)와 접촉마찰이 가장 크게되는데, 이러한 시트는 합성고무와 같은 것으로 형성되므로, 고온, 고압 또는 초저온과 같은 조건하에서는 소재의 변형이 발생하여 긴밀한 기밀성을 유지할 수 없는 사용상의 제한적 요인이 있었으며, 이러한 요인들에 의하여 편마모가 심하게 일어나 개폐디스크(400)의 기밀유지가 원활히 이루어지지 않게 되는 문제점이 있었다.However, in such a conventional butterfly valve, the opening and closing disk 400 to rotate in the transverse direction orthogonal to the axial direction (Y) of the rotation shaft 410 on the inner wall 201 of the seat 200. Therefore, the opening / closing disk 400 is in contact with the sheet 200 at both the outer point T of the center point 0 and the rotational axis 410 in the axial direction Y and the rotational orthogonal line X direction. The sheet is formed of a kind of synthetic rubber, and thus, there is a limiting factor in the use of which the deformation of the material occurs under conditions such as high temperature, high pressure, or ultra low temperature, so that tight tightness cannot be maintained. There was a problem that badly caused to keep the confidentiality of the opening and closing disk 400 smoothly.

그리하여, 최근에는 상기 시트(200)의 수명을 연장하기 위한 개선된 방향으로서 상기 회전축(410)의 축선방향(Y)를 상기 개폐디스크(400)의 중심점(0)과 편심되도록 설치하거나, 상기 회전축(410)의 축선방향(Y)을 상기 개폐디스크(400)으로 부터 간격을 크게 설치하여 줌으로서, 상기 개폐디스크(400)의 회전반경을 완만하게 하여 시트(200)의 내벽과 개폐디스크(400)의 외면과의 접촉마모율을 적게는 방법이 개시되고 있다.Therefore, in recent years, the axial direction (Y) of the rotating shaft 410 is installed to be eccentric with the center point (0) of the opening / closing disk (400) as an improved direction for extending the life of the sheet (200), or the rotating shaft By extending the axial direction (Y) of the (410) from the opening and closing disk 400, the radius of rotation of the opening and closing disk 400 is gentle to the inner wall of the seat 200 and the opening and closing disk 400 A method of reducing the contact wear rate with the outer surface of a) is disclosed.

그러나, 이러한 기술은 단순히 시트(200)의 편마모를 적게 하는 정도로서, 시트(200)의 편마모를 완전하게 배제할 수 없어 수명을 조금더 연장하는 정도에 그치고, 개폐디스크(400)의 설계변경에 따른 밸브의 전체 부피가 비대하여 실용적이 지 못한 단점이 있었다.However, such a technique merely reduces the amount of uneven wear of the sheet 200, and cannot completely exclude the uneven wear of the sheet 200, thus extending the service life a little longer, and according to the design change of the opening / closing disk 400. The overall volume of the valve was too large to have practical disadvantages.

또한, 배관과의 연결을 위해서는 밸브몸체에 상, 하측에 구성된 연결홈(500)을 이용하여 결합볼트로 연결을 이루어야 하는데, 결합구조특성상 연결홈(500)이 볼트보다 크게 형성되어 있고, 연결홈(500)이 형성된 부위가 배관에 구성된 플랜지에 접하지 않게 형성되어 있기 때문에 볼트결합에 따른 유격이 발생하여 완벽한 기밀성을 유지되지 않는 문제점이 있었다.In addition, in order to connect with the pipe, the connection body 500 must be connected to the valve body by using the coupling groove 500 formed on the upper and lower sides. Due to the coupling structure, the coupling groove 500 is formed larger than the bolt, and the coupling groove Since the portion where 500 is formed is not formed in contact with the flange formed in the pipe, there is a problem in that a play occurs due to the bolt coupling and thus perfect airtightness is not maintained.

상기와 같은 목적을 달성하기 위한 본 고안의 플랜지형 고성능 버터플라이밸브는 결합축에 연결되어 밸브몸체에 구성된 유체통로를 개폐하는 디스크로 구성되며, 결합부재의 체결에 의해 배관에 연결됨으로써 유체의 흐름을 제어하는 플랜지형 고성능 버터플라이밸브에 있어서, 유체통로의 A-A' 중심선으로부터 "a" 만큼 편심되어 설치되는 결합축; 상기 결합축에 결합되고, 밸브몸체의 B-B' 중심선으로부터 "b" 만큼 편심되어 설치되되, 결합축의 회전에 따라 회전되는 일방향의 외측둘레에는 경사가 형성되어 유체통로에 구성된 돌출턱에 밀착되며, 상기 돌출턱에 밀착되는 외측둘레에는 결합홈이 형성된 디스크; 상기 디스크의 결합홈에 끼워지는 끼임부와, 상기 끼임부의 외측에 구성되는 3개의 단으로 형성되어 유체통로를 완전 밀폐하는 강화테프론 재질의 시트; 상기 밸브몸체의 양측에 구성되는 연결홈이 형성된 연결플랜지;로 이루어지는 것에 특징이 있다.Flange-type high-performance butterfly valve of the present invention for achieving the above object is composed of a disk connected to the coupling shaft to open and close the fluid passage configured in the valve body, the fluid flow by being connected to the pipe by the coupling member coupling A flanged high performance butterfly valve for controlling a pressure, comprising: a coupling shaft eccentrically installed by "a" from an AA 'center line of a fluid passage; It is coupled to the coupling shaft, is installed eccentrically "b" from the BB 'center line of the valve body, the inclination is formed on the outer periphery in one direction rotated by the rotation of the coupling shaft is in close contact with the protruding jaw formed in the fluid passage, A disk having a coupling groove formed at an outer circumference closely contacting the protruding jaw; Reinforced Teflon sheet is formed of a fitting portion to be fitted into the coupling groove of the disk, and three stages configured on the outside of the fitting portion to completely seal the fluid passage; It is characterized in that consisting of; connecting flange formed with a connection groove formed on both sides of the valve body.

본 고안의 플랜지형 고성능 버터플라이밸브는 시트가 3단으로 구성될 뿐만 아니라, 편심되게 형성된 디스크의 외측둘레에 경사부가 형성되어 유체통로에 구성된 돌출턱에 완전히 밀착밀폐되기 때문에 고온고압에서의 고기밀성이 유지되는 장점이 있으며, 시트 마찰에 의한 마모가 억제는 물론, 부드러운 작동에 의해 내구성이 향상되는 장점이 있다.The flange type high performance butterfly valve of the present invention is not only composed of three stages, but also has an inclined portion formed on the outer circumference of the eccentrically formed disk so that it is completely in close contact with the protruding jaw formed in the fluid passage. This has the advantage of being maintained, and the wear due to the sheet friction is suppressed, as well as the durability is improved by the smooth operation.

또한, 본 고안은 밸브몸체의 양측에 구성된 연결플랜지에 의해 본 고안과 배관의 연결을 유격없이 이룰 수 있기 때문에 밸브의 견고한 설치를 용이하게 이룰 수 있는 유용한 고안이다.In addition, the present invention is a useful design that can easily achieve a solid installation of the valve because it can achieve the connection between the present design and the pipe by a connection flange configured on both sides of the valve body without any play.
