Description

내식 볼 밸브Corrosion resistant ball valve

제 1 도는 본 고안 볼 밸브의 전체 사시도.1 is an overall perspective view of a ball valve of the present invention.

제 2 도는 제 1 도의 A-A 절단선에 의한 종단면도.2 is a longitudinal sectional view taken along the line A-A of FIG.

제 3 도는 제 2 도의 B-B 절단선에 의한 횡단면도이다.3 is a cross sectional view taken along the line B-B of FIG.

본 고안은 내식 볼 밸브에 관한 것으로 특히 밸브체의 양측면에 압접하는 시이트링의 압접력을 균일하게 하는 고안에 관한 것이다.The present invention relates to a corrosion resistant ball valve, and more particularly, to a device for making the pressure contact force of the seat ring pressed against both sides of the valve body uniform.

공지의 볼 밸브에 있어서는 예를들면 실용신안 공보 제192호 (공번69-410호) 및 동 제350호(공번77-250호)에 게재되고 있는 바와 같이 밸브체의 양측에 시이트링을 압접하는 구성으로서 양측으로 분활된 케이싱에 프렌지를 형성하고, 그 프렌지 사이에 패킹을 개입시켜서 보울트로 체착함에 따라 양측 시이트링이 밸브체에 압접되게 하였다.In known ball valves, for example, as disclosed in Utility Model Publications No. 192 (No. 69-410) and No. 350 (No. 77-250), the seat rings are pressed against both sides of the valve body. As a constitution, a flange was formed in the casing divided on both sides, and both sides of the seat ring were pressed against the valve body by sticking through the packing between the flanges.

그러나 이와 같은 구성에 의하면 프랜지의 주면을 보울트로 균일하게 체착할 수 없는 문제점 때문에 밸브체에 대한 시이트링 주위의 압접력이 고르지 못하게 되고, 또 구경이 큰 볼 밸브에 있어서는 유체가 누출되는 부분이 생기기 쉬우므로 보울트의 체착력을 강력하게 하지 않으면 안되는 고로 회전축의 회동이 여의치 못하게 되어 밸브를 개폐하는 데 있어 상당한 노력이 들게 되는 문제점이 있었다.However, according to such a configuration, the pressure contact around the seat ring against the valve body becomes uneven due to the problem that the main surface of the flange cannot be uniformly attached to the bowl. There was a problem in that the effort to open and close the valve was not easy because the rotation of the rotary shaft is not easy because it is easy to tighten the bolting force.

본 고안은 이와 같은 문제점을 해소하고저 양측으로 분활된 케이싱의 대접면(對接面)에 패킹을 개입시키지 않고도 밸브체의 양측에 시이트링이 균일하게 압접되도록 구성한 것으로 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention solves such a problem and is configured such that the seat rings are uniformly pressed on both sides of the valve body without intervening the packing on the opposing surfaces of the casing divided into both sides. Same as

제 1 도는 본 고안 볼 밸브의 외관도로서 분활케이싱(1)(1')과 상면덮개판(3)으로 되었으며, 양 케이싱(1)(1')의 대접면(2)에는 패킹을 개입시키지 않고 외부에서 보울트(4)(4')로 체착하게 하였으며, 상면덮개판(3)은 보울트(5)로 양 케이싱(1)(1')의 상면에 체착하게 되어있다.1 is an external view of the ball valve of the present invention, which is composed of a split casing (1) (1 ') and a top cover plate (3). Without the bolts (4) (4 ') from the outside to be attached, the top cover plate (3) is to bolt to the upper surface of both casing (1) (1').

그리고 A-A 절단선에 의한 종단면도 (제 2 도)와 B-B 절단선에 의한 횡단면도 (제 3 도)를 보면, 밸브체(6)의 양측면에 내식층(7)을 형성한 상단한 두께의 금속링(8)(8')에 시이트링(9)(9')을 감입할 수 있게한 륜구(10)(10')를 형성하고, 또 금속링(8)(8')의 주위에는 돌출륜(11)(11')을 직각방향으로 돌설하여 그 돌출륜(11)(11')이 상기한 분활케이싱(1)(1')에 요설한 륜구(12)(12')에 각각 감입되게한 것이다. 그리고 밸브체(6)와 내식층(7) 및 밸브체(6)를 회전축(13)에 연결하는 4각축(14)과 시이트링(9)(9') 및 실린더(15)는 각각 내식성이 좋은 4불화수지로 제작된다.And the longitudinal cross-sectional view (FIG. 2) by the AA cutting line and the cross-sectional view (FIG. 3) by the BB cutting line show that the metal ring of the upper thickness which formed the corrosion-resistant layer 7 on both sides of the valve body 6 is shown. (8) (8 ') is formed with wheels (10) and (10') which allow the seat rings (9) and (9 ') to be inserted therein, and protruded wheels around the metal rings (8) and (8'). (11) (11 ') are projected in a right angle so that the protruding wheels (11) and (11') are respectively inserted into the wheels (12) and (12 ') provided for the split casing (1) (1'). It is. The quadrilateral shaft 14, the seat ring 9, 9 ′ and the cylinder 15 connecting the valve body 6, the corrosion resistant layer 7, and the valve body 6 to the rotary shaft 13, respectively, have corrosion resistance. Made of good tetrafluoro resin.

미설명 부호(16)은 "O"링이고 (17)은 핸들이다.Reference numeral 16 is an "O" ring and 17 is a handle.

상기한 바와 같이 구성된 본 고안은 시이트링(9)(9')이 밸브체(6)의 표면에 압착될 수 있는 소정치로 륜구(12)(12')의 위치를 설정하고, 대접면(2)이 서로 맞닿을 때 까지 보울트(4)(4')를 조이면 되는 고로, 종래의 볼 밸브와 같이 프렌지 사이에 패킹을 개입시키고 여러개의 보울트로 조임력을 조정하는 것과 같은 수단이 필요없고, 또 핸들(17)의 회전을 부드럽게 하면서 기밀이 유지되는 동시에 내식성이 우수한 볼 밸브를 제공하는데 손색이 없는 것이다.The present invention configured as described above sets the positions of the wheel openings 12, 12 'to a predetermined value at which the seat rings 9, 9' can be pressed against the surface of the valve body 6, Since the bolts 4 and 4 'are tightened until 2) comes into contact with each other, there is no need for a means such as through the packing between the flanges and adjusting the tightening force with several bolts as in the conventional ball valve. While smoothly rotating the handle 17, airtightness is maintained and at the same time providing a ball valve excellent in corrosion resistance.
