본 발명은 버터플라이 밸브에 관한 것으로, 더욱 상세하게는 밸브 개폐에 따른 시트의 밀착 접촉관계를 안정적으로 유도되게 함과 동시에, 그 시트 밀착부위로 탄성 압박력을 더 부가되게 하여, 보다 향상된 기밀성 유지기능과 내구성 증대기능을 행하도록 한 탄성 밀착시트를 구비한 버터플라이 밸브에 관한 것이다.The present invention relates to a butterfly valve, and more particularly, to stably induce a close contact relationship of a seat according to opening and closing of the valve, and to further add an elastic pressing force to the seat close contact portion, thereby maintaining an improved airtightness. It relates to a butterfly valve having an elastic contact sheet to perform the function of increasing the durability.

일반적으로 버터플라이 밸브라 함은 높은 기밀성을 요하는 시설물, 다시 말해 물, 기름, 가스등이 유동되는 배관라인에 설치된 상태로, 유체 및 기체의 흐름을 유도 또는 폐쇄토록 하는 데 이용되는 물품 구성임을 알 수 있다.In general, the butterfly valve is a component that is used to induce or close the flow of fluid and gas while installed in a piping line where water, oil, gas, etc. flow through a high airtight facility. Can be.

이에, 상기와 같은 용도로 사용되는 종래 버터플라이 밸브의 구성을 간략하게 살펴보면;Thus, briefly look at the configuration of a conventional butterfly valve used for the above purposes;

이는, 도 1로 도시된 바와 같은 구조로서, 먼저 유동통로(10)가 형성된 원통형 구조의 밸브본체(20)를 기초구성으로하여, 상기, 유동통로(10) 중앙 내주면에 밴드 구조의 몸통시트(30)를 일체로 부착시키고;This, as shown in Figure 1, as a basic configuration based on the valve body 20 of the cylindrical structure in which the flow passage 10 is first formed, the body seat of the band structure on the inner peripheral surface of the center of the flow passage ( 30) integrally attached;

이어, 상기, 몸통시트(30)가 부착된 유동통로(10) 중앙부에 그 유동통로(10)의 개,폐를 단속하는 회동축 연결구조로서, 디스크시트(40)가 장착된 밸브디스크(50)를 설치되게 하며;Subsequently, as a rotation shaft connection structure for controlling the opening and closing of the flow passage 10 at the central portion of the flow passage 10 to which the body seat 30 is attached, the valve disc 50 having the disc seat 40 mounted thereon. ) To be installed;

재차, 상기 밸브본체(20) 외측 일면에, 전술한 밸브디스크(50)의 개폐를 단속하는 구동 제어수단으로서, 동력모터와, 기어박스, 그리고 조작핸들 등으로 이루 어진 개폐 조작부(도시생략)를 일체로 설치하여 구성하는 것으로;Again, the drive control means for controlling the opening and closing of the valve disc 50 described above on one side of the valve body 20, the opening and closing operation unit (not shown) consisting of a power motor, a gear box, the operation handle, etc. Integrally installed and configured;

특히, 이와 같은 구성에 있어, 상기 몸통시트(30)와 디스크시트(40)는 그 기밀방법에 따라 금속, 비금속, 테프론 및 기타 고무등의 소재로 이루어진 다양한 재질의 시트를 선택적으로 설치, 이용하게 되는 것이다.In particular, in such a configuration, the body sheet 30 and the disk sheet 40 is to selectively install, use a sheet of a variety of materials made of a material such as metal, non-metal, Teflon and other rubber according to the airtight method Will be.

하지만, 전술한 바와 같은 구성으로 이루어진 종래의 버터플라이 밸브에 있어, 그 밸브로 적용되는 기밀수단, 다시 말해 몸통시트는 일련의 설치관계가 단순히 접착제에 의한 결합방식을 통해서만 이루어지는 것이었던바;However, in the conventional butterfly valve made of the above-described configuration, the airtight means applied to the valve, that is, the body seat was a series of installation relationship was made only through the bonding method by the adhesive;

이에, 밸브디스크의 반복적인 개,폐작동시 그 마찰저항과 응력집중 현상에 의해 몸통시트 내지 디스크시트가 쉽게 이탈되거나 손상되어 원할한 기밀성 유지기능을 수행하지 못하게 되는 등, 상당한 구조 및 사용상의 문제점을 주는 것이었으며,아울러 몸통시트를 설치 또는 교환하기 위한 일련의 작업과정에 있어서 또한, 임의적인 단순 접착방식에 의해 작업자가 세심한 노력을 기울이지 않을 경우, 몸통시트가 설정된 설치위치를 벗어나 정밀하지 못한 결합상태를 이루게 되는 등, 설치Therefore, the structure and use problems, such as the body seat or the disk seat is easily separated or damaged by the frictional resistance and stress concentration phenomenon during the repeated opening and closing of the valve disk, it is not possible to perform a function of maintaining the airtightness. In addition, in a series of operations for installing or replacing the body sheet, and also if the operator does not take great care by a simple simple adhesive method, the body sheet is not precisely set out of the set installation position Installation, etc.

작업상의 문제점을 갖게 하는 것이었으며;To have work problems;

또 다르게, 상기 버터플라이 밸브로 적용되는 종래의 디스크시트는 그 소재가 연성재질의 단순한 합성고무재로서, 완충작용에 의한 기밀성 유지기능은 우수하다 볼 수 있으나, 장시간 사용시 고무 노화현상에 따른 강도 및 내구성 저하로 인해 쉽게 손상 됨은 물론 몸통시트와의 압착시 접촉 마찰에 따른 과도한 토오크 작용으로 큰 동력을 요구하게 되는 등, 상당한 구조상의 문제점 또한 갖게 하는 것이었다.In addition, the conventional disk seat is applied to the butterfly valve is a simple synthetic rubber material of the soft material, it can be seen that the airtight retention function by the buffer action is excellent, but the strength and strength of the rubber aging phenomenon for a long time use Not only is it easily damaged due to the deterioration of durability, but also a considerable structural problem, such as requiring a large power due to excessive torque action due to contact friction when pressing the body sheet.

한편, 근래에는 전술한 버터 플라이밸브에 적용되는 시트의 구조를 일부 개선시킨 기술로서, 본 출원인에 의해 개발된 "시트조립구조를 개선시킨 기능성 버터플라이 밸브"가 선출원 등록(실용신안등록 제0406344호)된 바 있다.On the other hand, in recent years, as a technology that partially improved the structure of the seat to be applied to the above-described butterfly valve, the "application of the functional butterfly valve with improved seat assembly structure" developed by the applicant of the first application registration registration (Utility Model Registration No. 0406344) Has been done.

그러나, 이와 같은 선등록 기술로서의 버터 플라이밸브는 단순히 시트의 조립구조와 그 재질 정도를 개선 시킨 것에 불과한 것으로, 이에 밸브디스크의 반복적 개,폐작동시 각 시트의 이탈현상은 어느 정도 방지토록 한 것이기는 하나, 몸통시트와 디스크시트의 강한 마찰에 따른 마모현상과 과도한 토오크 발생으로 인해 큰 조작력을 갖게 하는 점은 여전히 해결하지 못한 상태를 갖는 것이었던바;However, the butterfly valve as a pre-registered technology merely improves the assembly structure of the seat and the degree of its material, and thus prevents the deviation of each seat during the repeated opening and closing of the valve disc. However, the point of having a large operating force due to the wear phenomenon and excessive torque caused by the strong friction of the body seat and the disc seat was still in a state that has not been solved;

따라서, 이와 같은 이유로 인해 기밀성 유지기능이 지속적이지 못하고, 높은 토오크를 요구하는 문제점을 갖는 것이었으며, 아울러, 그로 인해 시트의 교환주기 또한 단축되어 불필요한 수리비용 및 부품의 낭비를 초래되게 하는 등, 경제성과 내구성 저하라는 예견하지 못한 또 다른 문제점 들을 상존되게 하는 것이다.  Therefore, due to this reason, the airtightness maintenance function is not continuous and has a problem of requiring a high torque, and as a result, the replacement cycle of the seat is also shortened, resulting in unnecessary repair costs and waste of parts. And other unforeseen problems of poor durability.

따라서, 본 발명은 버터 플라이밸브에 적용되는 종래 몸통시트와 디스크시트의 제반적인 문제점을 해결하고자 창안된 것으로;Therefore, the present invention has been devised to solve the general problems of the conventional body seat and disk seat applied to the butterfly valve;

본 발명의 목적은 디스크시트 내측면에 탄력적 완충작용과, 압박기능을 행하는 탄성유도공을 구비되게 하고, 또 다르게, 몸통시트에는 다단형태를 취하는 이중 경사면 구조의 제1경사면과 제2경사면, 그리고, 압착걸림홈을 더 형성되게 하여, 밸브의 반복적 개폐 작동시 각 시트의 접촉관계를 슬라이드 방식에 의해 적은 토오크로 안정적으로 유도되게 하고, 역압발생시 디스크밸브의 닫힘상태를 유지되게 하며, 아울러, 상기 탄성유도공에 의한 탄력적 압박작용에 의해 시트 접촉부위의 밀착력을 더욱 증대되게 함으로서, 정방향 압력과 역방향 압력에 대해 양방향 동일하게 차단 성능을 유지되게 하여, 밸브 시트의 내마모성과 기밀성을 극히 향상되도록 한 탄성 밀착시트를 구비한 양압형 버터플라이 밸브를 제공함에 있다.An object of the present invention is to provide an elastic induction to the elastic sheet to the inner surface of the disk sheet and the pressing function, and alternatively, the first and second inclined surfaces of the double inclined surface structure having a multi-stage shape, and By further forming a crimping groove, the contact relationship of each seat can be stably guided to a small torque by a slide method during repeated opening and closing operation of the valve, and the disc valve is kept closed when the back pressure occurs, and the elasticity The elastic contact sheet to increase the adhesion of the seat contact portion by the elastic pressing action by the guide hole to maintain the same blocking performance against the forward pressure and the reverse pressure in both directions, to extremely improve the wear resistance and air tightness of the valve seat In providing a positive pressure butterfly valve having a.

한편, 본 발명의 또 다른 목적은, 내마모성과 기밀성 향상기능에 의해 시트의 변형 및 마모손실을 감소되도록 하여, 내구성을 증대되도록 하고, 아울러, 이와 같은 내구성 향상기능에 의해 부품의 사용수명 및 교환주기 또한 연장시킬수 있도록 한 탄성 밀착시트를 구비한 양압형 버터플라이 밸브를 제공함에 있다. On the other hand, another object of the present invention is to reduce the deformation and abrasion loss of the sheet by the wear resistance and airtightness enhancement function, to increase the durability, and also to increase the service life and replacement cycle of parts In addition, the present invention provides a positive pressure butterfly valve having an elastic contact sheet that can be extended.
