이와 같은 본 고안은 게이트밸브몸체(8)의 시트(801)에는 도4와 같이 밸브디스크(1)를 상하이동되게 끼우고 안내실(9)과 덮개(10)에는 스템(7)을 끼워 패킹그랜드(13)와 그랜드프랜지(14)로 빠지지 못하게 고정하고 전기의 스템(7)을 ㄱ자홀더(2)에 위치시킨 상하이동너트(6)에 나사맞춤하여 스템(7)을 좌우로 회전시키는 것에 의하여 밸브디스크(1)를 상하로 이동시켜 밸브를 개폐시키게 되는 것은 종래와 동일한 바,The present invention is such that the seat (801) of the gate valve body 8 is inserted into the valve disk (1) so as to move as shown in Figure 4 and the stem (7) in the guide chamber (9) and the cover (10) by packing gland By rotating the stem 7 to the left and right by fixing the stem 13 to the grand flange 14 and screwing the electric stem 7 into the shandong copper nut 6 located in the A-holder 2. The valve disc 1 is moved up and down to open and close the valve as in the prior art.
상기의 작동에 있어서 본 고안의 밸브디스크(1)는 ㄱ자홀더(2)에 할절부 (201)를 형성하여 전기의 할절부(201)를 요입홈(5)에 연통되게하여 밸브디스크(1) 전체가 양호한 탄력성이 발휘되도록 하였으므로 적은 마찰력에 의하여 밸브디스크 (1)의 상하작동이 매우 원활하게 이루어지게됨과 아울러 마모가 적어 사용수명을 오래 유지시킬 수 있고,In the above operation, the valve disk 1 of the present invention forms a cutout portion 201 in the A-shaped holder 2 so that the electric cutout portion 201 communicates with the recessed groove 5 so that the valve disk 1 Since the entire elasticity is exerted, the up and down operation of the valve disc (1) is made very smoothly due to the low frictional force, and the wear life is long, and the service life is long.
동파나 열변형을 자체의 탄력성에 의하여 흡수하기 때문에 이상온도시에도 누수발생을 방지할 수 있으며, 시트(801)에 이물질이 삽입되는 경우에도 양호한 탄력성에 의하여 작동이 불량하게 되는 것이 방지된다.Since it absorbs freezing waves or heat deformation by its elasticity, leakage can be prevented even at abnormal temperatures, and even when foreign matter is inserted into the sheet 801, the operation is prevented from being poor due to good elasticity.
이와 같은 본 고안은 ㄱ자홀더(2)에는 할절부(201)를 형성하여 전기의 할절부(201)를 요입홈(5)과 연통하여 양호한 탄력성이 발휘되도록 하였으므로 게이트밸브몸체(8)의 상하작동이 원활하게 이루어지게됨과 아울러 마모의 감소로 사용수명을 오래 유지시킬 수 있으며,The present invention is formed in the A-shaped holder (2) by forming a cut-out 201 to communicate the electrical cut-out 201 with the indentation groove 5 to exhibit a good elasticity, so the vertical operation of the gate valve body (8) Is smooth and the wear life is reduced for a long time.
동파나 열변형을 자체의 탄력흡수에 의한 누수방지와 게이트밸브의 시트 (801)의 탄력성에 의하여 작동이 불량하게 되는 것을 방지할 수 있는 효과가 있다.There is an effect that the operation of the freeze or heat deformation due to the elastic absorption of its own and the operation of the gate valve by the elasticity of the seat 801 can be prevented from being poor.
