Description

고무 버터플라이 밸브 {Rubber butterfly valve}Rubber Butterfly Valve {Rubber butterfly valve}

본 발명은 밸브에 있어서 상세하게는 밸브판이 위치하는 밸브몸체를 비교적 강도가 우수한 연질의 고무재를 이용하여 기능성을 향상한 고무 버터플라이 밸브에 관한 것이다.The present invention relates to a rubber butterfly valve in which the valve body in which the valve plate is located is improved in detail by using a soft rubber material having relatively high strength.

일반적인 밸브들은 매우 다양한 기능적 구성에 의하여 볼 밸브, 버터플라이밸브, 게이트밸브 등으로 구분할 수 있다.Common valves can be divided into ball valves, butterfly valves, gate valves, etc. by a wide variety of functional configurations.

도 5 는 본 발명이 적용될 수 있는 배관 예시도로서 도면을 참조하여 상기와 같은 밸브류의 사용을 설명하면 건물의 지하층이나 지하 주차장과 같은 지하층에 설치된 배수 집수정(1)에 고이는 오, 배수를 배출시키는 장치에서 집수정(1)에 고인 오수가 일정수위로 올라가면 수위센서(5)가 이를 감지하여 펌프(4)를 구동시킨다. 그러면 펌프의 구동에 의하여 흡수관(2)으로 오수가 흡입되고 필터(3)를 거처 펌핑되며 펌프(4)의 토출구에는 플렉시블관(6)을 설치하여 펌프(4)의 진동을 흡수하도록 하며 연이어 체크밸브(7)를 설치하여 배수되는 오수의 역류를 방지하고 연이어 본 발명에서 다루어지는 밸브와 같은 차단밸브(8)를 설치하고 펌프(4)의 배출압력을 흡수하는 수격방지기(9)를 상부에 설치하고 계절의 온도차이로 인한 관의 수축을 흡수하는 신축접속관(10)을 연결한 배수관(11)을 통하여 건물의 외부로 배수하도록 되는 배관 라인을 구성하여 사용하게 된다.5 is a diagram illustrating the piping to which the present invention can be applied. Referring to the drawings, the use of the valves described above will be described. When the sewage accumulated in the sump (1) in the discharge device rises to a certain level, the water level sensor (5) detects this to drive the pump (4). Then, the sewage is sucked into the absorption tube 2 by the driving of the pump, pumped through the filter 3, and a flexible tube 6 is installed at the discharge port of the pump 4 to absorb the vibration of the pump 4 Install a check valve (7) to prevent the backflow of sewage to be drained, and to install a shut-off valve (8), such as the valve to be dealt with in the present invention, and a water hammer (9) to absorb the discharge pressure of the pump 4 Installed in and used to configure the piping line to drain to the outside of the building through the drain pipe 11 connected to the expansion connection pipe 10 to absorb the shrinkage of the pipe due to the seasonal temperature difference.

상기와 같은 배관라인에 설치된 차단밸브(8)는 평상시에는 오픈되어 있는 상태에서 펌프로부터 압송되는 오수를 배출시키도록 하며 펌프(4)의 점검이나 보수 시에는 차단밸브(8)를 닫도록 하는 기능을 수행한다.The shut-off valve 8 installed in the pipe line as described above is to discharge the sewage pumped from the pump in the open state in normal times, and to close the shut-off valve 8 when checking or repairing the pump 4. Do this.

상기와 같은 배관라인에 사용되는 종래의 밸브들은 공통적으로 밸브를 조작하는 회전형 핸들을 외부에 부설하고 이의 핸들과 직결되는 밸브판이 밸브 하우징의 중앙에 천공된 유동로에 위치하고 이 유동로의 양단에 플렌지를 부설한 형상이다.Conventional valves used in such a pipe line are commonly provided with a rotary handle for manipulating the valve on the outside and a valve plate directly connected to the handle is located in a flow passage drilled in the center of the valve housing and located at both ends of the flow passage. It is a shape with a flange.

그러나, 상기한 종래 밸브들은 유동로를 형성하는 밸브 하우징과 플렌지가 일체로 형성된 금속체로 되어 있음으로 제조원가가 높고 주조에 의하여 제작됨으로 대량 생산의 어려움과 정밀한 가공이 어려운 문제점이 있다.However, the aforementioned conventional valves are made of a metal body integrally formed with the valve housing and the flange forming the flow path, and thus have a high manufacturing cost and are difficult to produce in a mass and difficult to process precisely.

그리고, 일체형의 밸브하우징에 형성된 플렌지는 서로 연관되어 연결되는 배관 라인과 정확히 일치되도록 시공하여야 하며 특히, 플렌지에 천공된 결속홀의 위치가 중요하고 배관라인에 직각이 되도록 취부각을 유지하여야 되는 시공의 불편함이 있다.In addition, the flange formed in the integral valve housing must be constructed so as to be exactly matched with the pipe line connected to each other. In particular, the position of the binding hole drilled in the flange is important and the mounting angle must be maintained so that it is perpendicular to the pipe line. There is discomfort.

또한, 상기와 같이 정확히 시공이 되어 있다하여도 사용중 진동이나 관의 수축에 의하여 플렌지 이음부에 균열이 발생하거나 변형이 발생하여 누수의 원인이 될수 있으므로 별도의 플렉시블 조인트와 신축 접속관을 병용하여야 되는 문제점이 있는 것이다.In addition, even if the construction is exactly as described above, because the cracks or deformation of the flange joint due to vibration or shrinkage of the pipe during use may cause leakage, it is necessary to use a separate flexible joint and a flexible connection tube together There is a problem.

본 발명은 종래와 같은 제반 문제점을 감안하여 발명된 것으로 밸브하우징과 플렌지를 별도의 독립된 부품으로 형성하여 유동되도록 하여 시공성을 향상하고, 밸브 하우징의 재질을 비교적 탄성과 강도가 우수한 고무류로 형성하여 시공성과 유지 관리가 향상된 밸브를 제공한다.The present invention has been invented in view of various problems as in the prior art, and the construction of the valve housing and the flange are formed in separate parts to improve flowability, and the construction of the valve housing is made of rubber having excellent elasticity and strength. Provides improved valve and maintenance.

상기와 같이 구성된 본 발명 밸브(20)의 작용을 보다 상세하게 설명하면 다음과 같다.Referring to the operation of the present invention valve 20 configured as described above in more detail as follows.

먼저, 본 발명은 밸브 하우징(30)의 재질이 강도가 우수한 연질의 고무류로 제조되어 약간의 유동성이 있는 밸브 하우징(30)이다.First, in the present invention, the material of the valve housing 30 is made of soft rubber having excellent strength, so that the valve housing 30 has some fluidity.

상기와 같은 본 발명의 밸브(20)는 밸브판(22)을 회동시키는 기어박스(27)를 설치하는 샤프트하우징(23)에 일체로 형성된 상부링(23a)과 하부링(24)에 의하여 밸브 하우징(30)의 외부를 감싸고 있음으로 밸브 하우징(30)의 외부를 보강함과 아울러 내부에 부설되는 밸브판(22)의 작동을 유지하도록 되어 있다.The valve 20 of the present invention as described above is formed by the upper ring 23a and the lower ring 24 integrally formed in the shaft housing 23 for installing the gearbox 27 for rotating the valve plate 22. By enclosing the exterior of the housing 30, the exterior of the valve housing 30 is reinforced and the operation of the valve plate 22 disposed therein is maintained.

상기와 같이 설치된 밸브판(22)은 밸브 하우징(30) 자체의 탄성 때문에 밸브판(22)과 밸브 하우징(30)의 접촉면이 완벽하여 기밀을 유지하게 되는 장점이 있다.The valve plate 22 installed as described above has an advantage that the contact surface between the valve plate 22 and the valve housing 30 is completely maintained due to the elasticity of the valve housing 30 itself.

한편, 밸브 하우징(30)의 양단에 조립된 플렌지(21)는 밸브 하우징(30)과 분리된 부품이고 접속림(30a)의 내측에 위치하고 있음으로 플렌지(21)에 접촉 연결되는 배관의 플렌지에 천공된 결속홀과 용이하게 회전시켜 일치시킬 수 있다.On the other hand, the flange 21 assembled at both ends of the valve housing 30 is a separate component from the valve housing 30 and is located inside the connection rim 30a, so that the flange 21 of the pipe contacted with the flange 21 is connected. It can be easily rotated and matched with perforated binding holes.

그리고, 접속림(30a)은 밸브 하우징(30)과 일체로 형성되어 있음으로 별도의 패킹을 이용하지 않고 직접 배관라인을 접속시켜 연결할 수 있게된다.And, since the connecting rim 30a is formed integrally with the valve housing 30, the connection rim 30a can be directly connected by connecting a pipe line without using a separate packing.

또한, 밸브 하우징(30)은 유연성이 있기 때문에 연결되는 배관라인의 위치의 오차가 있는 경우 용이하게 위치변경이 가능함으로 시공성을 용이하게 한다.In addition, since the valve housing 30 is flexible, it is easy to change the position when there is an error in the position of the pipe line to be connected to facilitate the construction.

상기와 같이 작용하는 본 발명의 밸브(20)는 예기치 않은 순간압력에 대하여탄력있게 흡수할 수 있음으로 인하여 플렌지의 이음부로부터의 누수를 방지할 수 있는 장점이 있고, 연결되는 배관라인의 플렌지 사이에 별도의 패킹을 사용하지 않아도 되는 장점에 따른 시공의 용이성을 향상하였으며, 연결된 배관라인의 수축에 따른 유동을 밸브에서 흡수함으로 별도의 플렉시블 조인트 부품을 사용하지 않아도 되는 편리성을 보강하고, 연결 플렌지 결속홀의 위치를 용이하게 변경함과 아울러 중심부의 위치 오차에 대하여 밸브 하우징의 유동을 이용하여 일치시킬 수 있는 시공의 편리성을 향상한 효과를 얻게 된다.The valve 20 of the present invention acting as described above has an advantage of being able to elastically absorb the unexpected instantaneous pressure, thereby preventing leakage from the joint portion of the flange, and between the flanges of the pipe line to be connected. The ease of installation is improved according to the advantage of not having to use a separate packing.In addition, by absorbing the flow due to the shrinkage of the connected pipe line from the valve, the convenience of not using a separate flexible joint part is reinforced, and the connection flange The position of the binding hole can be easily changed, and the convenience of construction can be improved by using the flow of the valve housing to match the position error of the center part.
