수도용 게이트밸브의 플렉시블 밸브디스크구조{FLEXIBLE VALVE DISC STRUCTURE OF GATE VALVES FOR WATER WORKS}FLEXIBLE VALVE DISC STRUCTURE OF GATE VALVES FOR WATER WORKS

본 발명은 수도용으로 사용되는 수도용 게이트밸브의 플렉시블 밸브디스크구조에 관한 것으로서,The present invention relates to a flexible valve disc structure of a water gate valve used for water,

특징은, 스테인레스제로 된 밸브디스크의 ㄱ자홀더에 할절부를 형성하여 탄력성을 부여함으로서 마찰마모감소에 의한 작동이 원활하게 이루어지게함과 아울러 누수방지효율을 향상시킬 수 있도록 하고, 또한 사용수명을 연장시킬 수 있도록 한 것이다.The special feature of the valve disc is made of stainless steel, so that the cutout is formed to give elasticity to smoothly operate by reducing friction wear and to improve the leakage preventing efficiency and to extend the service life. It was made to be possible.

하부로 점차 좁게 형성한 밸브디스크(1)는 도4와 같이 게이트밸브몸체(8)의 시트(801)에 상하이동되게 끼우고 안내실(9)과 볼트(11)및 너트(12)로 고정한 덮개 (101)의 내로 스템(7)을 끼워 스템(7)의 단부는 ㄱ자홀더(2)에 위치시킨 상하이동너트(6)에 나사맞춤하고 스템(7)이 빠지지 못하도록 패킹그랜드(13)와 그랜드프랜지(14)로 고정한 후 스템(7)을 좌우로 회전시키는 것에 의하여 상하로 이동시켜 개폐작용을 하게 되는 것으로서,The valve disc 1, which is gradually narrowed downward, is inserted into the seat 801 of the gate valve body 8 as shown in FIG. 4 and fixed with a guide chamber 9, a bolt 11, and a nut 12. Insert the stem (7) into the (101) end of the stem (7) is screwed into the shank copper nut (6) located in the A-shaped holder (2) and the packing grand 13 and gland to prevent the stem (7) from falling out After fixing with the flange 14 is to move up and down by rotating the stem 7 to the left and right to open and close,

중앙에 형성된 안내구멍(3) 양측에는 ㄱ자홀더(2)가 형성되고 양측에는 한쌍의 가이드돌편(4)을 형성하여서 된 종래의 밸브디스크(1)는 도5 및 도6과 같이 ㄱ자홀더(2)의 하부둘레에는 요입홈(5)이 형성되었으나 ㄱ자홀더(2)는 일체로되어 탄력성(彈力性)이 매우 불량하여 게이트밸브몸체(8)와의 마찰력이 크기 때문에 밸브디스크(1)의 상하작동이 원활하게 이루어지지 않음과 아울러 마모의 촉진으로 사용수명이 짧고, 또한 초기 몇회는 시링(SEALING)이 양호하게 이루어진다 하겠으나 곧 누수가 발생되고 동파나 열변형에 대하여 탄력되면서 자체 흡수하지 못함으로 인한 누수가 발생되었으며,A-shaped holder (2) is formed on both sides of the guide hole (3) formed in the center, and a pair of guide protrusions (4) are formed on both sides of the conventional valve disc (1) as shown in Figs. In the lower circumference of the bottom circumferential groove 5 is formed, but the A-shaped holder (2) is integrated, the elasticity is very poor and the friction force with the gate valve body (8) is large, the vertical operation of the valve disc (1) In addition, the service life is shortened due to the accelerated wear and the sealing is good for the first few times, but the leak is generated due to the failure of self-absorption due to the leakage and elasticity against freezing or thermal deformation. Has occurred,

게이트밸브의 시트(SEAT)에 이물질이 삽입될 때에는 밸브디스크(1)의 탄력성 (휨성)의 불량으로 상하작동에 큰 힘을 요하게되어 작동이 원활하게 이루어지지 못하게되는 문제가 있었다.When the foreign matter is inserted into the seat (SEAT) of the gate valve there is a problem in that the operation is not performed smoothly because the large force is required for the up and down operation due to poor elasticity (flexibility) of the valve disk (1).

본 발명은 상기와 같은 문제점을 해결하기 위하여 중앙에 형성된 안내구멍 (3)의 양측에는 ㄱ자홀더(2)를, 한쌍의 가이드돌편(4)을 형성한 밸브디스크(1)의 외면에는 요입홈(5)을 형성하여서 된 것에 있어서,In order to solve the above problems, the present invention provides a recessed groove on the outer surface of the valve disc 1 on which the A-shaped holder 2 is formed at both sides of the guide hole 3 formed at the center, and the pair of guide protrusions 4 are formed. In forming 5),

ㄱ자홀더(2)에는 할절부(201)를 형성하여 전기의 할절부(201)를 요입홈(5)과 연통하여 양호한 탄력성이 발휘되도록 함으로서 게이트밸브몸체(8)와의 마찰력의 감소로 밸브디스크(1)의 상하작동이 원활하게 이루어지게함과 아울러 마모의 감소로 사용수명을 오래 유지시킬 수 있으며,In the A-shaped holder 2, a cutout 201 is formed to communicate the cutout 201 with the recess 5 so that good elasticity is exerted, thereby reducing the friction force with the gate valve body 8, thereby reducing the valve disc ( The up and down operation of 1) can be made smoothly and the service life can be maintained for a long time by reducing wear.

또한 동파나 열변형을 자체의 탄력흡수에 의한 누수방지와 게이트밸브의 시트(801)에 이물질이 삽입될 때에도 밸브디스크의 탄력성에 의하여 작동이 불량하게 되는 것을 방지할 수 있도록 한 플렉시블 밸브디스크구조를 제공할 수 있도록 한 것이다.In addition, the flexible valve disc structure to prevent leakage caused by the elastic absorption of the freezing wave or heat deformation and the operation of the valve disc by the elasticity of the valve disc even when foreign matter is inserted into the seat 801 of the gate valve It is to be provided.
