Description
본 발명은 수도나 가스의 공급관에 설치되는 밸브에 관한 것으로, 디스크와 밸브대가 상하 슬라이드 하여 열고 닫히며 맨홀의 높낮이에 따라 설치가 용이하게 구성되는 높낮이 조절형 슬라이드 밸브에 관한 것이다.The present invention relates to a valve installed in the supply pipe of water or gas, and relates to a height-adjustable slide valve that the disk and the valve stem slides up and down to open and close, and easy to install according to the height of the manhole.
수도나 가스 등을 공급하기 위한 공급관에는 여러곳에 분기관이 설치되고 이 분기관마다 밸브가 장착되 유입되는 수도나 가스를 차단시킬 수 있도록 하여 공사나 사고의 발생시 유입량을 조절하거나 차단시키게 된다.Branch pipes are installed in several places in the supply pipe for supplying water or gas, and valves are installed at each branch pipe to block inflow of water or gas, thereby controlling or blocking inflow during construction or accidents.
상기 공급관들은 일반적으로 지하에 매설되 밸브 또한 지하에 설치되는 것이 보편적이며 밸브가 설치될 장소에는 밸브의 작동과 보호를 위해서 지면에 맨홀이 시공된다.The supply pipes are generally buried underground but the valve is also installed underground, and the manhole is installed on the ground for the operation and protection of the valve in the place where the valve is to be installed.
맨홀안에서 분기관 등에 설치되는 종래의 밸브는 도면에 나타낸 도 1 과 같이 T형상의 몸체(100)가 분기관상에 결합되며 몸체(100)상측에 덮개(102)와 패킹덮개(103)가 부착되 기밀을 유지하기 위한 패킹들이 내장되고 몸체(100)내의 디스크(101)는 작동캡(105)이 상단에 끼워진 밸브대(104)에 스크류방식으로 장착되 있어 밸브작동키(106)를 작동캡(105)에 물려 회전시킴으로써 디스크(101)가 상하 작동해 열고 닫히는 구조이다.In a conventional valve installed in a branch pipe in a manhole, as shown in FIG. 1, a T-shaped body 100 is coupled to a branch pipe, and a cover 102 and a packing cover 103 are attached to an upper side of the body 100. Packings for maintaining airtightness are built in, and the disk 101 in the body 100 is mounted in a screw manner to the valve seat 104 having the actuating cap 105 fitted on the upper end thereof, so that the actuation cap 106 is actuated. ), The disk 101 is opened and closed by vertically actuating and rotating.
상기와 같은 종래의 밸브는 디스크가 밸브대의 하단에 스크류나사 방식으로 결합되 있기 때문에 밸브의 개폐시 밸브작동키에 무리한 힘이 가해지면 밸브대와 디스크의 나사결합부가 마모되면서 공회전되 작동이 불가능한 상태에 놓이게 되는데, 이는 맨홀안에 설치된 밸브를 노면위에서 조작하기 위한 밸브작동키의 핸들을 작업자가 무리한 힘을 가해 회전시키기 때문이다.In the conventional valve as described above, when the disk is coupled to the lower end of the valve stem by a screw screw method, when an excessive force is applied to the valve operation key when the valve is opened or closed, the valve joint and the screw coupling portion of the disk are worn out and cannot be operated. This is because the operator rotates the handle of the valve operation key for excessive force to operate the valve installed in the manhole on the road surface.
또한 밸브작동기를 노면위에서 회전시킬 때 핸들에 유동하는 힘이 발생해 작동캡이 좌우로 힘이 가해지며 회전됨으로 패킹덮개와 덮개가 결합력을 잃고 유동하여 기밀성이 떨어져 누수가 발생하는 문제점이 야기되고 있다.In addition, when the valve actuator is rotated on the road surface, a force that flows to the handle is generated and the operating cap is applied to the left and right, and the packing cover and the cover lose the bonding force and flow, which causes leaks due to air tightness. .
또한 밸브가 설치된 맨홀안이 오수로 침수되면 작동캡이 보이지 않아 밸브작동키를 물리지 못해 작업시간이 지연되는 문제점들이 야기되 막대한 예산낭비를 초래하고 있다.In addition, if the manhole installed with the valve is flooded with sewage, the operation cap is not visible and the operation time is delayed because the operation key is not bited, causing huge budget waste.
본 발명은 밸브대와 디스크가 일체로 형성돼 상하 슬라이드 하여 열고 닫히며 맨홀의 높낮이에 따라 설치가 용이하게 높이 조절이 가능한 밸브를 제공하기 위한 것이다.The present invention is to provide a valve that is formed integrally with the valve stem and the disk slides up and down to open and close, the height can be easily adjusted according to the height of the manhole.
이러한 본 발명은 T형상의 몸체내에서 디스크가 상하 작동해 열고 닫는 구조로 이루어진 밸브를 구성함에 있어서,In the present invention, in the configuration of a valve consisting of a structure in which the disk is opened and closed by operating the disk up and down in the T-shaped body,
상측단에 나사볼트가 형성되고 기밀을 위한 오링이 끼워진 밸브대가 구비된 디스크와, 상기 디스크가 내장되는 몸체의 상부에 결합되 밸브대가 끼워져 오링이 상하 이송하는 슬라이드홈이 디스크의 개폐범위보다 길게 형성되는 덮개와, 상기 밸브대의 나사볼트에 깊숙히 끼워져 체결되 회전에 의해 상하 이송가능한 이송대와, 상기 이송대가 부착된 고정구에 일측이 고정되 이송대를 상하 이송시켜 디스크를 작동시키는 밸브개폐장치와, 상기 밸브개폐장치가 회전가능케 장착되 맨홀몸체의 내측에 고정 결합되는 고정대로 구성되는 것을 특징으로 하는 것이다.A disk having a screw bolt formed at an upper end and having a valve seat fitted with an O-ring for airtightness, and a slide groove which is coupled to an upper part of the body in which the disk is embedded, and has a valve seat inserted to convey the O-ring up and down longer than the opening and closing range of the disk.
