본 고안은, 승강하는 밸브체(게이트)를 원통형으로 형성하고, 그 외주면에 탄성원통체를 피복하여 되는 게이트 밸브에 관한 것으로서, 여기에 다시 밸브체의 유로폐색면에 해당되는 부분에 환상의 융기줄을 일체 형성하여서 된것을 특징으로 하는 것이다.The present invention relates to a gate valve in which a lifting and lowering valve body (gate) is formed in a cylindrical shape and the elastic cylinder is coated on its outer circumferential surface, and the annular ridge is formed on the portion corresponding to the channel closed surface of the valve body. It is characterized by being formed in one line.

통상적으로, 게이트 벨브는, 밸브본체 속을 평판형상 혹은 하방으로 좁아지는 쐐기판 형상의 밸브체(게이트)가 승강해서 유로를 개폐하는 것이나, 본 고안에 있어서는, 약간 하방으로 좁아진 원통형상의 밸브체가 유로를 사이에 두고 상하로 통하는 원형구멍으로 된 밸브상자에 감합해서 승강하여, 유로를 폐색하는 것으로서, 유체의 압압력을 받는 밸브체와 이것을 둘러싼 밸브상자가 함께 단면이 원형이기 때문에 가공정밀도가 높은것을 용이하게 만들수가 있고, 따라서 뛰어난 봉지성을 유지할 수가 있다.In general, the gate valve is a valve body (gate) having a wedge plate shape that narrows in the valve body in a flat or downward direction to open and close the flow path, but in the present invention, a cylindrical valve body narrowed slightly downward is a flow path. The valve box is fitted with a circular hole that passes up and down with a gap between them, and lifts and closes the flow path. It can be made easily, and therefore the outstanding sealing property can be maintained.

그러나, 이와같이 정밀하게 가공된 밸브체, 밸브상자에 있어서는 유체속에 혼입되어 있는 모래 등의 경질입자에 의해 흠집이 생기기 쉽다. 이를 위해서는 밸브체 혹은 밸브상자의 한쪽에, 균일하게 압접해서 충분한 봉지성을 발휘하고, 더우기 모래 등의 경질입자가 끼어들어 갔을때는 경질입자에 압박되어서 용이하게 변형할 수 있는 유연성을 갖는 탄성체를 장착해 두면 되는것이나, 이와같은 탄성체 피복으로는 밸브체와 밸브상자의 접촉마찰이 대단히 커져서 원활한 밸브조작을 행할수 없고, 그렇다고 해서 해당피복을 밸브상자의 유로와의 개구부 즉 밸브시이트 주연에 테두리 형상으로 착설해서 국부적으로 압접시킨 구조로는 곧 박탈되어서 실용성이 없다.However, in such a precisely processed valve body and a valve box, scratches are likely to occur due to hard particles such as sand mixed in the fluid. To this end, an elastic body is mounted on one side of the valve body or the valve box to uniformly press-fit and exhibit sufficient encapsulation properties, and furthermore, when a hard particle such as sand is inserted, it is pressed against the hard particle and easily deformed. In this case, the frictional contact between the valve body and the valve box is so great that smooth valve operation cannot be performed. The structure which was built and locally pressed was soon deprived and it was not practical.

이에 대하여, 본 고안은 상기의 점을 고려해서 밸브체를, 그 외부면에 넓게 탄성체를 피복시킴과 동시에 그, 특히 밸브시이트 가장자리에 접한 부분에는 밸브시이트 테두리에 연하는 윤곽의 융기줄을 일체로 형성하므로서, 밸브시이트와의 접촉면적을 국부적으로 제한해서 마찰저항을 적게하는 것에 의해 상기 목적을 달성하고, 더우기 봉지성을 향상시킨 것이다.On the other hand, in view of the above point, the present invention covers the valve body with a wider elastic body on the outer surface thereof, and at the same time, in particular, the ridge line of the contour connected to the valve seat edge is integrally formed at the part contacting the valve seat edge. The above object is achieved by locally limiting the contact area with the valve seat to reduce the frictional resistance, and furthermore, the sealing property is improved.

본 고안의 실시예를 도면에 따라서 설명하면, 제1도는 본 고안의 게이트 밸브의 종단측면도로서, (1)은 밸브본체이며, 양단 플랜지로 이어지는 유로(2)(2), 직립부분(3)으로 이루어져 있어, 내부에는 직립부분(3) 내면에서부터 유로(2)(2)내면을 절삭하여 구멍 가장자리에 밸브시이트(5')(5')를 각각 형성함과 동시에 하단이 원형으로 오목하게 파인 구멍(4)으로 된 밸브상자(5)가 그 하방에 약간 좁아지는 원통형 직립구멍으로서 형성되어 있다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a longitudinal sectional side view of a gate valve of the present invention, where (1) is a valve body and flow paths (2) (2) and upright portions (3) leading to flanges at both ends. The inner side of the upright portion 3 is cut from the inner surface of the flow path 2, 2 to form the valve seats 5 'and 5' at the edges of the holes, respectively, and at the same time, the lower end is recessed in a circular shape. The valve box 5 made of the holes 4 is formed as a cylindrical upright hole that narrows slightly below.

다음에, (6)은 밸브체로서, 제2도에서 명백한 바와같이 주위면을 밸브상자(5)내에 적합하는 1/100~1/50정도의 테이퍼를 가진 원추경사면으로 하고, 상부 중심에 암나사부(7), 상단의 직경방향으로 상대한 양단위치에 결합돌기(8)(8)를 가진 원통형 부재로서 형성되고, 주위면에는 미리 상기 한쌍의 밸브시이트(5')(5')에 압접해야 될 환상의 융기줄(9)(9)이, 내부주위 가장자리를 상기 구멍부분에 대체로 합치하는 크기로 해서 1~2mm의 높이로 일체 성형되어 부가 형성되어 있다. 환상의 융기줄(9)(9)의 단면형상은 특히 한정되지 않으나, 도시되여 있는 바와같이 단면반원 형상으로 설치하면, 본원의 목적이 충분히 달성되여지므로 바람직한 것으로 된다. 이 경우, 이 밸브체(6)는 원주형상의 심체(6')의 외부면에, 별도로 고무, 합성수지 등으로 된 두께 2~10mm의 탄성원통체(10)를 감착 접착해서 형성되어 있다.Next, (6) is a valve body, and as shown in FIG. 2, the peripheral surface is a conical inclined surface having a taper of about 1/100 to 1/50 that fits in the valve box 5, and a female screw is provided at the upper center. Part 7 is formed as a cylindrical member having engaging projections 8 and 8 at both ends in the radial direction of the upper end, and abuts against the pair of valve seats 5 'and 5' in advance on the peripheral surface. The annular ridges 9 and 9 to be formed are formed integrally with a height of 1 to 2 mm, with the inner periphery having a size that substantially conforms to the hole portion. The cross-sectional shape of the annular ridges 9 and 9 is not particularly limited. However, the cross-sectional shape of the annular ridges 9 and 9 is preferable because the object of the present application is sufficiently achieved. In this case, the valve body 6 is formed by attaching and adhesively attaching an elastic cylindrical body 10 having a thickness of 2 to 10 mm made of rubber, synthetic resin, or the like to the outer surface of the cylindrical core 6 '.

이 밸브체(6)는, 결합돌기(8)(8)를 직립부분(3)의 내면에 형성된 안내줄(11)(11)에 결합해서 회동하는 일없이 밸브상자 내를 접동 승강하는 것으로서, 이 승강은 정상의 암나사부(7)에 삽입한 숫나사부(12)에 연결된 스핀돌(13)의 회전에 의해서 행해진다.The valve body 6 slides up and down the valve box without engaging and engaging the engaging projections 8 and 8 with the guide lines 11 and 11 formed on the inner surface of the upright part 3, This lifting and lowering is performed by the rotation of the spin stones 13 connected to the male screw portion 12 inserted into the normal female screw portion 7.

본 고안은 상기와 같은 구조로서, 앞서 설명한 바와같이 밸브체(6)의 외부면에는 2~10mm의 두께로 탄성원통체(10)가 장착되어 있으나, 이 탄성원통체(10)의 상기 환상융기줄(9)(9)이외부분의 표면은, 밸브상자(5) 내부면에 그대로 적합하는 외경으로 만들어져 있으며, 환상의 융기줄(9)(9)만이 상기 표면보다 더 1~2mm 돌출되어 있어, 이 부분에 밸브시이트(5')(5'), 즉 밸브상자(5)의 유로(2)(2)에 개구하는 구멍가장자리 부분에 압축상태로 위치하도록 되어있기 때문에, 밸브체 폐색시에 있어서의 봉지성의 극히 양호하고, 또 모래등의 경질입자가 끼어들어 갔을 경우에도 이 경질입자는 탄성원통체(10)의 주위면 적소에 몰입상태로 유지되기 때문에 밸브상자의 내부면을 손상시킬 염려가 없다.The present invention has the structure as described above, the elastic cylinder 10 is mounted on the outer surface of the valve body 6 to a thickness of 2 ~ 10mm as described above, the annular ridge of the elastic cylinder 10 The surface of the portion other than the strings 9, 9 is made of an outer diameter suitable for the inner surface of the valve box 5, and only the annular bumps 9, 9 protrude 1 to 2 mm more than the surface. In this case, the valve seat 5 ', 5', i.e., is positioned in a compressed state at the edge of the hole opening in the flow passage 2, 2 of the valve box 5, so that the valve body is closed. The encapsulation property is extremely good, and even when hard particles such as sand are interrupted, the hard particles remain immersed in place at the periphery of the elastic cylinder 10, which may damage the inner surface of the valve box. There is no.

그리고 밸브체(6)의 밸브상자(5)내부면에 대한 압접부분은 밸브시이트(5')(5')와, 이 밸브시이트(5')(5')표면에 대응하는 환상의 융기줄(9)(9)표면에만 한정되어 있으므로 양자의 접촉면적이 작아지고, 따라서서 마찰저항이 작아지는 까닭에 밸브체(6)의 승강은 종래보다도 낮은 스핀돌 돌크로 용이하게 행할 수가 있다.And the press-contacting part with respect to the inner surface of the valve box 5 of the valve body 6 is valve seat 5 '(5') and an annular ridgeline corresponding to this valve seat 5 '(5') surface. (9) (9) Since it is limited only to the surface, the contact area of both becomes small and hence the frictional resistance becomes small, so that the lifting and lowering of the valve body 6 can be performed easily with a lower spin dollol than before.
