복합시트 구조형 버터플라이 밸브{A dual seat-type butterfly valve}Composite seat structure butterfly valve {A dual seat-type butterfly valve}

본 고안은 복합시트 구조형 버터플라이 밸브에 관한 것으로, 상세하게는 디스크의 주연부에 메탈과 고무로 된 두개의 디스크시트가 설치되어 바디시트에 이중으로 접촉됨으로써 수밀성이 향상된 복합시트 구조형 버터플라이 밸브에 관한 것이다.The present invention relates to a composite seat structured butterfly valve, and more particularly, to a composite seat structured butterfly valve having watertightness by double contacting the body seat with two disc seats of metal and rubber installed at the periphery of the disc. will be.

일반적인 버터플라이 밸브를 개폐하는 시트는 본체를 이루는 바디에 설치된 바디시트와, 상기 바디시트의 내부에서 회동되어 개폐되는 원형의 디스크의 주연부에 설치된 디스크시트로 구성된다. 상기의 디스크시트는 주로 메탈이나 고무 중 어느 하나로 형성되어 설치된다.The seat for opening and closing a general butterfly valve is composed of a body seat installed in the body constituting the body, and a disk seat installed at the periphery of the circular disk rotated and opened inside the body seat. The disk sheet is mainly formed of any one of metal or rubber is installed.

즉, 종래의 디스크시트는 메탈이나 고무 등으로 형성되어 그 중 어느 하나만이 디스크에 설치됨으로써, 마모나 설치상의 비틀림 등에 의해 수밀성이 저하되는 문제점이 있었고, 이를 방지하거나 예비된 수단의 구비가 없어 누수로 생기는 피해를 줄일 수가 없었다.That is, the conventional disk sheet is formed of a metal or rubber, and any one of them is installed on the disk, there is a problem that the water-tightness is lowered due to wear or torsional distortion, etc., there is no prevention or there is no provision of a means for water leakage Could not reduce the damage caused.

본 고안의 목적은 상기와 같은 종래의 문제점을 해결하기 위하여, 디스크시트를 이중으로 설치하되, 그 각각을 하나는 메탈재의 시트로 하고 다른 하나는 고무재의 시트로 함으로써 어느 일측이 마모로 누수가 되더라도 다른 측의 수밀성이 있어 누수로 인한 문제점을 방지할 수 있고, 두개의 시트에 의해 수압 등의 하중과 작동에 의한 힘을 분산하여 받을 수가 있어 마모의 정도가 작게 됨으로써 버터플라이 밸브의 수명과 수밀성이 증대되는 복합시트 구조형 버터플라이 밸브를 제공함에 있다.The purpose of the present invention is to solve the conventional problems as described above, the disk sheet is installed in a double, each one of which is a sheet of metal material and the other is a sheet of rubber material, even if one side is leaked by wear Watertightness on the other side prevents the problem caused by water leakage, and the two seats can distribute the loads such as hydraulic pressure and the force due to the operation. An increased composite seat structured butterfly valve is provided.

이하 본 고안의 구성 및 작용을 첨부 도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

본 고안은 바디(1)의 내부에 축설되어 회동되는 디스크(2)의 주연부에 설치되어 바디(1)의 내측에 환설된 바디시트(3)에 접촉되는 디스크시트를 구성함에 있어서, 상기 디스크(2)의 주연부에 메탈디스크시트(4)와 고무디스크시트(5)가 일정 간격을 두고 함께 설치되어 구성된다.The present invention is installed in the periphery of the disk (2), which is built up and rotated inside the body (1) to constitute a disk sheet in contact with the body sheet (3) rounded inside the body (1), the disk ( At the periphery of 2), the metal disc sheet 4 and the rubber disc sheet 5 are installed together at regular intervals.

상기의 메탈디스크시트(4)는 다양한 방법으로 디스크(2)에 설치되어 고정되는데, 우선 메탈디스크시트(4)는 디스크(2)와 일체로 형성될 수도 있는데 이 경우는 디스크(2)의 주연부가 메탈디스크시트(4)의 역할을 하는 것이고, 메탈디스크시트(4)가 체결볼트(6)에 의해 디스크(2)에 설치될 경우는 디스크(2)와 메탈디스크시트(4)에 체결공이 형성되고 상기 체결공에 체결볼트(6)가 나사결합되어 설치되는 구조를 가지며, 메탈디스크시트(4)가 용접에 의해 디스크(2)에 부착될 수도 있다.The metal disk sheet 4 is installed and fixed to the disk 2 in various ways. First, the metal disk sheet 4 may be formed integrally with the disk 2, in which case the peripheral edge of the disk 2 is used. When the metal disk sheet 4 is installed on the disk 2 by the fastening bolts 6, the fastening holes are formed on the disk 2 and the metal disk sheet 4. It is formed and has a structure in which the fastening bolt 6 is screwed to the fastening hole is installed, the metal disk sheet 4 may be attached to the disk (2) by welding.

그리고, 고무디스크시트(5)가 디스크(2)에 체결되는 구조는 체결볼트(6)에 의해 디스크(2)에 고정되는 체결환대(7)가 상기의 고무디스크시트(5)를 압지하여 디스크(2)에 설치되는 구조를 가진다.In addition, the structure in which the rubber disk sheet 5 is fastened to the disk 2 is such that the fastening ring 7 fixed to the disk 2 by the fastening bolt 6 presses the rubber disk sheet 5 to the disk. It has a structure installed in (2).

이와같이 구성된 본 고안은 이중으로 된 디스크시트에 의해 수밀성이 향상되고 버터플라이 밸브의 수명이 증대된다.The present invention constructed as described above has a double disk seat, which improves watertightness and increases the life of the butterfly valve.

버터플라이 밸브의 개폐작동은 디스크(2)의 회동에 의해 이루어지고, 이에 따라 디스크시트와 바디시트(3)가 접촉되거나 이탈되어 수밀과 개구가 반복적으로 이루어진다.The opening and closing operation of the butterfly valve is performed by the rotation of the disk 2, whereby the disk seat and the body seat 3 are brought into contact with or separated from each other and watertightness and opening are repeated.

상기와 같은 반복 작동에 의하여 디스크시트는 마모가 발생되고 수밀성이 저하됨으로써 버터플라이 밸브의 수명이 다하게 되는데, 본 고안은 수밀성의 증대를 통한 버터플라이 밸브의 내구수명을 증대시키는 구성을 가지게 된다.By the repeated operation as described above, the disk seat is worn out and the watertightness is deteriorated, the service life of the butterfly valve runs out, the present invention has a configuration that increases the durability life of the butterfly valve through the increase in watertightness.

즉, 본 고안은 디스크(2)의 회동에 의한 마찰과 수압 등의 충격하중에 의해 시트가 받는 하중을 분산시켜 디스크시트의 마모를 저하시키고 이중으로 수밀되게 하는 구조를 가진다.That is, the present invention has a structure in which the load applied to the sheet is dispersed by the frictional load caused by the rotation of the disk 2 and the impact load such as water pressure, thereby reducing the wear of the disk sheet and double sealing.

첨부도면에 도시된 바와 같이 본 고안은 메탈디스크시트(4)와 고무디스크시트(5)가 나란히 디스크(2)의 주연부에 병설되어 있고, 디스크(2)의 회동에 의해 바디시트(3)에 순차적으로 접촉되어 이중으로 밀폐되는 구조를 가지게 된다. 따라서 디스크시트가 접촉되는 면적이 넓기 때문에 수압 등에 의한 충격하중이나 밀폐시의 접촉력이 분산됨으로써 마모가 저하되어 내구 수명이 증대되게 된다.As shown in the accompanying drawings, the present invention includes a metal disk sheet 4 and a rubber disk sheet 5 arranged side by side at the periphery of the disk 2, and are rotated on the body sheet 3 by the rotation of the disk 2. The sequential contact is to have a double sealed structure. Therefore, since the disk sheet is in contact with a large area, the impact load due to hydraulic pressure or the contact force at the time of sealing is dispersed, thereby reducing wear and increasing durability life.

뿐만 아니라, 본 고안은 설치나 충격에 의해 어느 하나의 디스크시트의 초기 설치 상태에 변형이 일어난 경우는 다른 하나의 디스크시트가 수밀을 유지하고 있기 때문에 어느 정도의 변형까지는 수밀을 유지시킬 수 있어, 종래와 같이 하나의 디스크시트를 갖는 경우에 비하여 수밀성이 보장된다.In addition, the present invention can maintain the watertight up to a certain degree of deformation because the other disc seat maintains watertightness when deformation occurs in the initial installation state of one of the discsheets due to installation or impact. Watertightness is ensured as compared with the case of having one disc sheet as in the prior art.

또한, 본 고안은 메탈디스크시트(4)와 고무디스크시트(5)를 체결볼트(6)에 의해 체결되는 구조에서는 일정 수준 마모된 디스크시트를 교체하여 사용하기가 용이하여 작업성이나 비용면에 있어 장점을 가지게 된다.In addition, the present invention is easy to use by replacing the worn disk sheet to a certain level in the structure in which the metal disk sheet 4 and the rubber disk sheet 5 is fastened by the fastening bolt (6) in terms of workability or cost There is an advantage.

이와같이 본 고안은 디스크(2)의 주연부에 메탈디스크시트(4)와 고무디스크시트(5)를 병설시킴으로써, 마모를 야기시키는 힘들을 분산시켜 내구수명을 증대시키는 효과와 동시에 어느 하나의 수성밀이 저하되더라도 다른 하나의 수밀성에 의해 전체 수밀성이 보장되는 상보적인 효과가 있다.As such, the present invention provides the metal disk sheet 4 and the rubber disk sheet 5 at the periphery of the disk 2, thereby dispersing the wear-causing forces and increasing the durability life. Even if it is lowered, there is a complementary effect of ensuring the total watertightness by the other watertightness.
