Description
본 고안은 제수밸브(Sluice-Valve)장치에 관한 것으로서, 더욱 상세하게는 유로를 개폐하는 밸브디스크와 밸브디스크를 승강시키는 밸브로드를 일체로 형성함으로써, 제작성이 향상되고 또한 밸브로드가 외부로 노출되지 않도록 함으로써, 개폐작용이 원활하고 내구성이 향상되는 제수밸브장치에 관한 것이다.The present invention relates to a dilution valve (Sluice-Valve) device, and more particularly, by integrally forming a valve disk for opening and closing the flow path and the valve rod for lifting the valve disk, the manufacturability is improved and the valve rod to the outside By not being exposed, the opening and closing action is smooth and the durability relates to a distillation valve device.
일반적으로 제수밸브는 상,하수도관 등에서 고압 고속으로 유량이 많을 때에주로 사용된다. 도 1은 종래 밸브장치의 단면도를 나타낸 것으로 생활용수, 공업용수, 및 유류 등의 유체가 흐르는 유로관(101)과 유로관(101)을 개폐하는 밸브디스크(103) 및 밸브디스크(103)가 승강식으로 출입되는 출입구(100a)를 갖는 밸브케이싱(100)이 구비된다. 밸브케이싱의 출입구(100a) 상단에는 이를 밀폐하는 커버(109)가 구비되며 커버(109)의 중앙에는 밸브디스크(103)와 연결된 밸브로드(105)가 관통된 상태로 구비된다. 밸브로드(105)는 그 하단에 걸림턱(107)이 형성되고 밸브디스크(103)의 상단에는 걸림턱(107)에 걸려 밸브디스크(103)가 밸브로드(105)와 함께 승강되도록 안내하는 걸림고리(108)가 각각 형성된다.In general, the water separator valve is mainly used when the flow rate is high at high pressure and high speed in water and sewage pipes. 1 is a cross-sectional view of a conventional valve device, in which a fluid flow pipe 101 through which fluids such as living water, industrial water, and oil flow, and a valve disc 103 and a valve disc 103 for opening and closing the flow path 101 are A valve casing 100 having an entrance and exit 100a that is lifted in and out is provided. A cover 109 is provided at an upper end of the entrance and exit 100a of the valve casing, and a valve rod 105 connected to the valve disc 103 is provided at the center of the cover 109. The valve rod 105 has a catching jaw 107 formed at a lower end thereof, and a catching guide for allowing the valve disc 103 to be elevated together with the valve rod 105 by being caught at the catching jaw 107 at an upper end of the valve disc 103. Rings 108 are each formed.
커버(109)의 상단에는 밸브로드(105)의 외주면에 형성된 숫나사부(106)에 체결되어 밸브로드(105)의 승강을 안내하는 너트(110)가 구비되고 밸브로드(105)의 상단에는 커버(109)로부터 연장된 홀더(111)에 끼워지는 너트부(112)를 통하여 밸브로드(105)를 승강시키는 핸들(113)이 구비된다.The upper end of the cover 109 is provided with a nut 110 which is fastened to the male threaded portion 106 formed on the outer circumferential surface of the valve rod 105 to guide the lifting and lowering of the valve rod 105. The handle 113 which raises and lowers the valve rod 105 through the nut part 112 fitted to the holder 111 extended from 109 is provided.
이처럼 구성된 종래의 밸브장치는 도 1에 도시된 바와 같이 밸브디스크(103)가 하강되어 유로관(101)이 막힌 상태에서 유로관(101)을 개방하기 위해 핸들(113)을 회전시키면 핸들의 너트부(112)가 홀더(111)를 중심으로 헛돌게 되며 이 과정에서 숫나사부(106)가 너트부(112)의 나사산을 타고 넘어가면서 밸브로드(105)가 상승된다. 밸브로드(105)가 상승되면 이의 하단 걸림턱(107)과 연결된 걸림고리(108)를 통하여 밸브디스크(103)가 함께 상승되고 유로관(101)이 개방된다.In the conventional valve device configured as described above, as shown in FIG. 1, when the valve disc 103 is lowered and the flow path 101 is blocked, the handle 113 is rotated to open the flow path 101. The part 112 is circumferentially centered on the holder 111, and in this process, the male thread part 106 rides on the thread of the nut part 112 and the valve rod 105 is raised. When the valve rod 105 is raised, the valve disc 103 is raised together through the locking ring 108 connected to the lower locking jaw 107 and the flow path 101 is opened.
그러나 종래의 밸브장치는 밸브디스크(103)의 양단면에 형성된 시이트(104)를 별도로 부착해야 되는 단점이 있었다. 시이트(104)는 유로관(101)의 시이트면(102)과 접하여 누수를 방지해야 되고 또한 시이트면(102)과 붙고 떨어지는 과정에서 마찰에 따른 마모를 방지하기 위해 황동재질로 만들어진다. 따라서 주물에 의한 주철 등으로 제작되는 밸브디스크와 황동 재질의 시이트(104)를 열융착 또는 기타 다른 방법으로 부착하는 공정이 필요함으로 제작성이 저하된다.However, the conventional valve device has a disadvantage in that the sheets 104 formed on both end surfaces of the valve disc 103 must be separately attached. The sheet 104 should be in contact with the sheet surface 102 of the flow path tube 101 to prevent leakage, and also be made of brass to prevent abrasion due to friction in the process of adhering and falling off the sheet surface 102. Therefore, since the process of attaching the valve disk and the brass sheet 104 made of cast iron by casting or the like by heat fusion or other method is required, the manufacturability is reduced.
또한 종래 밸브장치는 밸브디스크(103)와 밸브로드(105)가 서로 분리 구성된 상태에서 이들이 걸림턱(107)과 걸림고리(108)에 의해 연결된 상태임으로 운반도중 또는 설치된 상태에서 외부의 강한 충격 등이 밸브케이싱에 가해지면 이들이 서로 분리되어 밸브디스크가 작동되지 못하게 됨으로 취급에 주의를 필요로하게 된다.In addition, the conventional valve device is a state in which the valve disk 103 and the valve rod 105 are separated from each other in a state in which they are connected by the locking jaw 107 and the locking ring 108 in the transport or installed state, such as strong external shocks When applied to these valve casings, they are separated from each other and the valve disc becomes inoperable, requiring care in handling.
더욱이 종래의 밸브장치는 밸브로드(105)가 외부로 노출된 상태에서 이의 숫나사부(106)가 외부로 노출됨으로 부식이 가속화 되며 밸브로드(105)를 회전지지하기 위해 너트(110)(112)와 홀더(111) 등의 부품과 구조물이 필요함으로 구성이 복잡해 지는 등의 단점이 있었다.In addition, the conventional valve device is exposed to the outside of the male rod portion 106 in the state in which the valve rod 105 is exposed to the outside, the corrosion is accelerated and the nut 110, 112 to support the rotation of the valve rod 105 And parts and structures such as the holder 111, such as the configuration is complicated, such as a disadvantage.
도 2는 종래 다른 실시예의 밸브장치의 단면도 이다. 이는 유로관(201)과 출입구(200a) 및 밸브디스크(203)를 갖는 밸브케이싱(200)이 구비되고 밸브케이싱(200)의 상부에는 밸브디스크(203)를 승강시키는 밸브로드(207)를 안내하는 슬리브(211)와 커버(210)가 각각 구비된다. 밸브로드(207)는 출입구(200a) 쪽에 숫나사부(208)가 형성되어 있으며 숫나사부(208)에 체결되는 너트부(209)는 밸브디스크(203)의 직상부에 구비된다. 밸브디스크(203)는 그 상측에 너트부(209)를 잡아주는 홀더(206)가 형성되며 밸브로드(207)의 상단에는 핸들(213)을 결합할수 있는 핸들캡(212)이 구비된다.Figure 2 is a cross-sectional view of a valve device of another conventional embodiment. It is provided with a valve casing 200 having a flow path tube 201, an entrance 200a, and a valve disc 203, and guides the valve rod 207 for elevating the valve disc 203 on the upper portion of the valve casing 200. Sleeve 211 and cover 210 are provided respectively. The valve rod 207 has a male screw portion 208 formed at the entrance 200a and a nut portion 209 fastened to the male screw portion 208 is provided directly above the valve disc 203. The valve disc 203 has a holder 206 holding the nut 209 on the upper side thereof, and a handle cap 212 capable of engaging the handle 213 on the upper end of the valve rod 207.
이처럼 구성된 종래 다른 실시예의 밸브장치는 도 2에 도시된 바와 같이 유로관(201)이 막힌 상태에서 핸들(213)을 회전시키면 밸브디스크(203)의 상단에 걸린 너트부(209)가 밸브로드(207)의 숫나사부(208)의 나사산을 타고 넘으면서 상승되며 너트부(209)가 상승되는 동안 홀더(206)를 통하여 연결된 밸브디스크(203)가 함께 상승되어 유로관이 개방된다.As shown in FIG. 2, in the conventional valve device configured as described above, when the handle 213 is rotated while the flow pipe 201 is blocked, the nut part 209 caught on the upper end of the valve disc 203 is connected to the valve rod ( The valve disc 203 connected through the holder 206 is raised together while the nut 209 is raised while the nut 209 is raised while the nut 209 is raised, and the flow path tube is opened.
그러나 종래 다른 실시예의 밸브장치는 밸브디스크(203)의 내부에 밸브로드(207)가 출입되는 구멍(204)이 형성되어 있기 때문에 유체에 포함된 이물질 등의 슬러지가 누적되면 밸브로드(207)의 회전 조작이 원활하게 이루어지지 않게되는 문제가 발생된다. 그리고 유로관(201)의 시이트면(202)과 접하는 시이트(205)가 밸브디스크(203)와 다른 재질로 제작된 상태에서 시이트(205)와 밸브디스크(203)가 열융착 등의 방법으로 부착되어야 함으로 제작과정이 복잡할뿐 아니라, 밸브디스크(203) 내부에 밸브로드(207)가 출입하는 구멍(204)을 형성하여야 됨으로 밸브디스크(203) 자체의 형상이 크게 형성되고, 이에 따라 밸브케이싱(200) 까지도 크게 형성하게 됨으로서 전체적으로 밸브가 대형화되는 결점이 있는 것이었고, 밸브케이싱(200) 외부로 노출된 밸브로드(207)가 작업상 부주의로 인하여 절손되는 경우가 발생하는 등의 문제점이 있는 것이었다.However, since the valve device 204 of another conventional embodiment has a hole 204 through which the valve rod 207 enters and exits, the sludge such as foreign matter contained in the fluid accumulates in the valve rod 207. There is a problem that the rotation operation is not made smoothly. Then, the sheet 205 and the valve disc 203 are attached by heat fusion or the like in a state where the sheet 205 in contact with the sheet surface 202 of the flow path tube 201 is made of a material different from that of the valve disc 203. In addition, the manufacturing process is not only complicated, but the valve rod 207 has to be formed in the valve rod 207 in and out of the hole 204 so that the shape of the valve disc 203 itself is large, and thus the valve casing. As a result of the formation of a larger size up to 200, the valve was largely enlarged, and the valve rod 207 exposed to the outside of the valve casing 200 was damaged due to inadvertent operation. Was.

By eliminating the need for mounting, the configuration is simplified, and the valve rod formed by the screw rod is screwed with the sleeve nut, and the upper part of the sleeve nut is sealed with the handle cap to integrate the valve rod so that durability is improved because the valve rod is not exposed to the outside. A dividing valve device is provided.
