본 발명은 역수방지 밸브장치에 관한 것으로서, 더욱 상세하게는, 펌프의 토출부나 배수로 등에 설치되어 일방향 토출만 가능하고 역수를 차단할 수 있게 설치되는 역수방지 밸브장치에 관한 것이다.The present invention relates to a backwater prevention valve device, and more particularly, to a backwater prevention valve device installed in a discharge part or a drainage path of a pump to be capable of only one-way discharge and to block backwater.

일반적으로, 역수방지 밸브장치는 펌프의 토출부나 배수로에 설치되는 것으로서, 펌프의 방류수로 단부에 설치되는 경우, 펌프 가동시에는 오수 또는 폐수가 배출될 수 있도록 밸브가 개방되고, 펌프 정지시에는 방류된 오수 또는 폐수 및 외수의 역류를 차단하기 위하여 밸브가 자동으로 역류 압력에 의해 폐쇄되는 것이다.In general, the backwater prevention valve device is installed in the discharge part or the drainage path of the pump, and when installed at the end of the discharge path of the pump, the valve is opened so that sewage or waste water can be discharged when the pump is running, and discharged when the pump is stopped. The valve is automatically closed by the backflow pressure in order to block the backflow of the wastewater or the wastewater and the external water.

또한, 이러한 역수방지 밸브장치를 배수로의 배수 갑문 토출수로 단부에 설치하는 경우, 외수의 수위 상승시 역류를 방지하도록 밸브가 자동으로 역류 압력에 의해 폐쇄된다.In addition, when such a backwater prevention valve device is installed at the end of the drainage lock discharge water in the drainage channel, the valve is automatically closed by the backflow pressure to prevent backflow when the water level rises.

이러한 종래의 역수방지 밸브장치는, 도 1에 도시된 바와 같이, 펌프의 토출부나 배수로 등에 설치되어 일방향 토출만 가능하고 역수를 차단할 수 있도록 토출구조물(1) 및 개폐문(2)으로 이루어지는 구성이다.As shown in FIG. 1, the conventional backwater prevention valve device includes a discharge structure 1 and an opening / closing door 2 installed in a discharge part or a drainage path of a pump to allow only one-way discharge and to block back water.

여기서, 상기 토출구조물(1)은, 오수, 폐수, 수위조절수 등을 방출할 수 있는 토출구(1a)가 형성된 것으로서, 상기 토출구(1a)는 상기 개폐문(2)이 중력에 의해 상기 토출구(1a)를 덮을 수 있도록 소정 각도로 경사지게 형성된다.Here, the discharge structure 1 is formed with a discharge port (1a) for discharging sewage, waste water, water level control water, etc., the discharge port (1a) is the discharge door (1a) by the gravity of the discharge opening (1a) ) Is formed to be inclined at a predetermined angle to cover.

또한, 상기 개폐문(2)은, 상기 토출구(1a)를 덮어 밀폐하는 것으로서, 일방 향 개방이 가능하도록 상기 토출구조물(1)과 상하회동이 가능하게 상하회동 힌지축(3)에 의해 힌지결합되는 구성이였다.In addition, the opening and closing door 2 is to cover and close the discharge port (1a), which is hinged by the vertically pivoting hinge shaft (3) to enable the up and down rotation with the discharge structure (1) to enable one-way opening. It was a composition.

따라서, 오수, 폐수, 수위조절수 등이 토출구(1a)에 도달하여 상기 개폐문(2)을 가압하면 상기 개폐문(2)은 상기 상하회동 힌지축(3)을 중심으로 상측방향으로 회동하면서 개방되고, 개방된 틈으로 오수, 폐수, 수위조절수 등이 배출될 수 있는 동시에, 반대로 역류의 경우, 외수의 압력에 의해 상기 개폐문(2)이 하측방향으로 회동하여 상기 토출구(1a)를 덮어 폐쇄할 수 있는 것이다.Therefore, when sewage, wastewater, water level control water, etc. reaches the discharge port (1a) and presses the opening and closing door (2), the opening and closing door (2) is opened while rotating in the upper direction around the vertical pivot hinge shaft (3) In the case of reverse flow, the opening / closing door 2 rotates downward to cover and close the discharge port 1a by the pressure of external water. It can be.

그러나, 이러한 종래의 역수방지 밸브장치는, 상기 개폐문(2)이 상하방향으로만 회동될 수 있기 때문에 파도나, 이물질의 충돌이 상기 개폐문(2)의 좌우방향으로 발생하는 경우, 좌우방향의 충격을 전혀 흡수할 수 없어서 상기 개폐문(2) 또는 상기 개폐문의 상하회동 힌지축(3)이 충격으로 쉽게 파손되어 역류가 침입하거나 오동작을 일으키거나 내구성이 떨어지는 등 많은 문제점이 있었다.However, such a conventional backwater prevention valve device, since the opening and closing door 2 can be rotated only in the up and down direction, when a wave or foreign matter collision occurs in the left and right directions of the opening and closing door 2, the impact in the left and right directions Since the opening and closing door 2 or the up-and-down pivoting hinge shaft 3 of the opening and closing door is easily damaged by shock, there are many problems such as backflow intrusion, malfunctioning, or poor durability.

또한, 종래의 역수방지 밸브장치는, 오수, 폐수 수위조절수 등이 저유량으로 흐르는 경우, 상하방향으로만 개폐문(2)이 회동하기 때문에 상기 개폐문(2)의 회동이 자유롭지 못하여 토출구(1a) 사이의 틈이 쉽게 막히는 등 저유량 통과가 어려웠었던 문제점이 있었다.In addition, in the conventional backwater prevention valve device, when the sewage, wastewater level control water, etc. flows at a low flow rate, the opening / closing door 2 rotates only in the vertical direction, so that the opening / closing door 2 is not free to rotate and the discharge port 1a. There was a problem that it was difficult to pass low flow rate, such as a gap between them easily.

또한, 종래의 역수방지 밸브장치는, 상기 개폐문(2)과 토출구(1a) 사이가 평평하여 나뭇가지나 막대 등 각종 이물질이 끼이기 쉽고, 이물질이 끼이는 경우, 개폐문(2)의 무게로 인해 이를 제거하기가 매우 어려웠었던 문제점이 있었다.In addition, the conventional backwater prevention valve device is flat between the opening and closing door (2) and the discharge port (1a) is easy to get caught in various foreign matters, such as branches and rods, if the foreign matter is caught, due to the weight of the opening and closing door (2) There was a problem that was very difficult to remove.

상기와 같은 문제점을 해결하기 위한 본 발명의 목적은, 개폐문이 상하방향은 물론, 좌우방향으로도 회동되어 파도나, 이물질의 충돌시 모든 충격을 흡수할 수 있고, 부품의 파손을 방지할 수 있으며, 역류가 침입이나 오동작을 방지하여 내구성을 향상시킬 수 있고, 저유량 통과를 용이하게 하며, 상기 개폐문과 토출구 사이에 로울러를 설치하여 이물질의 끼임을 방지하고, 끼인 이물질의 제거를 용이하게 할 수 있게 하는 역수방지 밸브장치를 제공함에 있다.An object of the present invention for solving the above problems, the opening and closing door is rotated not only in the vertical direction, but also in the left and right direction can absorb all the impact during the impact of waves, foreign matters, and can prevent the damage of parts To prevent the inflow or malfunction of the reverse flow, it can improve the durability, it is easy to pass the low flow rate, by installing a roller between the opening and closing door and the discharge port to prevent the jamming of foreign matters, it is easy to remove the foreign matters.
