Description

펌프의 흡입구 밸브Inlet valve of the pump

본 고안은 펌프의 흡입구를 개폐시키는 밸브에 관한 것으로, 더욱 상세하게는 펌프의 정지시 신속하게 흡입구를 폐쇄시킬 수 있도록 하여 별도의 압력탱크를 사용하지 않고도 펌프 내부의 압력을 유지할 수 있도록 한 펌프의 흡입구 밸브에 관한 것이다.The present invention relates to a valve for opening and closing the inlet of the pump, and more particularly, it is possible to close the inlet quickly when the pump stops to maintain the pressure inside the pump without using a separate pressure tank Relates to an inlet valve.

일반적으로, 펌프는 구동모터에 의해 압력이 작용하여 액체 또는 기체를 수송하는 장치로, 도 1과 도 2에서 보이는 바와 같이, 펌프(1) 흡입력의 압력에 의해 흡입되는 물은 수원으로부터 흡입 파이프(10)에 구비된 흡입구(11)를 통해 펌프(1)의 내부로 흡입된 후 토출된다.In general, the pump is a device for transporting a liquid or gas by the pressure acting by the drive motor, as shown in Figs. 1 and 2, the water sucked by the pressure of the pump (1) suction force from the water source to the suction pipe ( It is sucked into the pump 1 through the suction port 11 provided in 10 and then discharged.

한편, 펌핑작동은 펌프(1) 내부에 일정량의 물이 충진되어 있어야만 수행할 수 있으며, 이에 따라, 흡입 파이프(10)에는 펌프(1) 내부에 유입된 물이 흡입구(11)를 통해 외부로 누수되지 않도록 하기 위한 밸브(20)가 설치되고, 이 밸브(20)는 펌핑작동시에는 흡입구(11)를 개방시키며, 펌핑의 정지시에는 흡입구(11)를 폐쇄시켜 펌프(1) 내부의 물이 누수되지 않도록 하고 있다.On the other hand, the pumping operation can be performed only when a certain amount of water is filled in the pump (1), accordingly, the water introduced into the pump (1) in the suction pipe (10) to the outside through the suction port (11) A valve 20 is installed to prevent leakage, and the valve 20 opens the inlet 11 when the pumping operation, and closes the inlet 11 when the pumping stops to close the water in the pump 1. This prevents leaks.

이러한 종래 흡입구 개폐밸브(20)는 도 2와 도 3에 나타난 바와 같이, 원형으로 이루어지며, 중앙부에는 흡입구(11)를 개폐시키는 커버부(21)가 구비되며, 커버부(21)의 외주 방향으로는 흡입 파이프(10)의 플랜지(12)에 밀착 고정되는 고정부(22)가 형성되고, 커버부(21)와 고정부(22)는 연결부(23)에 의해 연결되며, 고정부(22)의 상부에는 흡입 파이프(10)의 플랜지(12)에 삽입 고정되는 고정돌기(24)가 구비된다.2 and 3, the conventional inlet opening and closing valve 20 is formed in a circular shape, and a central portion is provided with a cover portion 21 for opening and closing the inlet 11, and the outer circumferential direction of the cover portion 21. The fixing portion 22 is formed in close contact with the flange 12 of the suction pipe 10, the cover portion 21 and the fixing portion 22 are connected by the connecting portion 23, the fixing portion 22 The upper part of the) is provided with a fixing protrusion 24 that is inserted and fixed to the flange 12 of the suction pipe 10.

이와 같이 구성된 펌프의 작동을 간단히 설명하면, 구동모터에 전원이 인가되어 펌핑작동이 개시되면 펌프(1) 내부의 압력이 상승하여 펌프(1) 내부와 외부에는 압력차가 발생되고, 이 압력차에 의해 커버부(21)가 연결부(23)를 중심으로 회전하면서 흡입구(11)를 개방시키게 된다.Briefly describing the operation of the pump configured as described above, when power is applied to the driving motor and the pumping operation is started, the pressure inside the pump 1 rises, and a pressure difference occurs inside and outside the pump 1, As a result, the cover part 21 rotates about the connection part 23 to open the suction port 11.

이어서, 외부의 물은 흡입구(11)를 통해 펌프(1)의 내부로 유입된다.Subsequently, external water flows into the pump 1 through the inlet 11.

펌프(1) 내부로 유입된 물은 토출구를 통해 토출된다.Water introduced into the pump 1 is discharged through the discharge port.

반대로, 구동모터가 정지되어 물이 토출되지 않으면 순간적으로 펌프(1) 내부의 압력이 높아지게 되며, 이에 의하여, 펌프(1) 내부와 외부의 압력차 및 밸브(20)의 복원력이 동시에 작용하여 커버부(21)는 연결부(23)의 안내를 받으며 오픈시와 반대 방향으로 회전하면서 흡입구(11)를 폐쇄시키게 된다.On the contrary, if the driving motor is stopped and no water is discharged, the pressure inside the pump 1 is increased momentarily, whereby the pressure difference between the pump 1 and the outside and the restoring force of the valve 20 simultaneously act to cover the cover. The unit 21 is guided by the connecting unit 23 and closes the inlet 11 while rotating in the opposite direction as when opened.

그러나, 종래 펌핑작동의 정지시 밸브(20)의 커버부(21)가 흡입구(11)를 완전히 폐쇄시키기 까지 많은 양의 물이 누수되었으며, 이렇게 되면, 다음 펌핑작동을 수행할 수 없으므로 다음 수행되는 펌핑작동을 위해 압력탱크(3)를 사용하여 펌프(1) 내부의 압력을 유지하였다.However, a large amount of water leaked until the cover portion 21 of the valve 20 completely closes the inlet port 11 when the pumping operation is stopped. In this case, the next pumping operation cannot be performed. The pressure tank 3 was used to maintain the pressure inside the pump 1 for the pumping operation.

그러나, 종래 흡입구 개폐밸브(20)에 의하면, 흡입구(11)를 개폐시키는 커버부(21)의 개폐성능은 연결부(22)의 탄성력에 의해 결정되는데 종래 밸브(20)의 연결부(22)와 커버부(21)의 폭을 비교하면 연결부(23)의 폭이 커버부(21)의 폭에 비해 매우 좁기 때문에 커버부(21)를 복원시키는데 오랜 시간이 소요되었다.However, according to the conventional inlet opening and closing valve 20, the opening and closing performance of the cover portion 21 for opening and closing the inlet 11 is determined by the elastic force of the connecting portion 22, but the connecting portion 22 and the cover of the conventional valve 20 Comparing the width of the portion 21 it takes a long time to restore the cover portion 21 because the width of the connecting portion 23 is very narrow compared to the width of the cover portion 21.

따라서, 커버부(21)가 복원되면서 흡입구(11)를 완전히 폐쇄시키기 이전까지 펌프(1) 내부의 물이 누수되며, 이를 보상하기 위해 별도의 압력탱크(3)를 사용하므로 장치 구입 및 유지 보수에 따른 비용이 상승하는 문제점이 있었다.Therefore, the water inside the pump 1 leaks until the cover 21 is completely closed until the inlet 11 is completely closed. To compensate for this, a separate pressure tank 3 is used to purchase and maintain the device. There was a problem that the cost increases.

본 고안은 상술한 문제점을 해소하기 위해 안출된 것으로, 펌프의 정지시 밸브의 커버부가 신속하게 복원되면서 흡입구를 폐쇄시켜 별도의 압력탱크를 사용하지 않고도 다음 펌핑작동이 정상적으로 수행될 수 있도록 함으로써 비용을 절감할 수 있도록 한 펌프의 흡입구 밸브를 제공하려는데 그 목적이 있다.The present invention was devised to solve the above-mentioned problems, and the cost of the next pumping operation can be normally performed without using a separate pressure tank by closing the inlet port while the cover part of the valve is quickly restored when the pump is stopped. The purpose is to provide an inlet valve for a pump that can be saved.

상술한 목적을 달성하기 위한 본 고안은, 흡입구를 개폐쇄시키는 커버부와, 상기 커버부의 외주 방향으로 소정 거리 이격 형성되며 흡입구 파이프에 밀착 고정되는 고정부와, 상기 커버부와 고정부를 연결하는 연결부를 포함하며, 상기 연결부의 폭을 상기 커버부 폭의 1/2 이상으로 형성한 것을 특징으로 한다.The present invention for achieving the above object, the cover portion for opening and closing the inlet, the fixed portion is formed in a predetermined distance spaced in the outer circumferential direction of the cover portion fixed to the inlet pipe tightly, connecting the cover portion and the fixing portion It includes a connecting portion, characterized in that the width of the connecting portion is formed to be 1/2 or more of the width of the cover portion.

이하, 본 고안에 따른 흡입구 밸브를 첨부도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, the inlet valve according to the present invention will be described in detail with reference to the accompanying drawings.

도 4는 본 고안에 따른 실시예의 정면도이며, 설명의 편의를 위해 종래와 동일한 구성부재에 대해서는 동일한 부재번호를 부여한다.4 is a front view of an embodiment according to the present invention, and for convenience of description, the same member numbers are assigned to the same members as in the prior art.

이에 도시된 바와 같이, 본 고안에 따른 흡입구 밸브는, 흡입구(11)를 개폐시키는 커버부(21)와, 커버부(21)의 외주 방향으로 소정 거리 이격되게 위치되며 흡입 파이프(미도시)의 단면에 밀착 고정되는 고정부(22)와, 커버부(21)와 고정부(22)를 연결시키는 연결부(23)를 포함하며, 연결부(23)의 폭은 커버부(21)의 폭보다 약간 좁게 형성한다.As shown in this, the inlet valve according to the present invention, the cover portion 21 for opening and closing the inlet port 11, the cover portion 21 is located at a predetermined distance apart in the circumferential direction of the suction pipe (not shown) And a fixing portion 22 which is tightly fixed to the end surface, and a connecting portion 23 connecting the cover portion 21 and the fixing portion 22, wherein the width of the connecting portion 23 is slightly smaller than the width of the cover portion 21. To form narrowly.

연결부(23)의 폭은 커버부(21) 폭의 1/2 이상으로 형성하는 것이 바람직하다.It is preferable that the width of the connection portion 23 is formed to be 1/2 or more of the width of the cover portion 21.

고정부(22)의 상측 외주 단부에는 흡입 파이프(10)에 고정되는 고정돌기(24)가 구비된다.The upper outer peripheral end of the fixing portion 22 is provided with a fixing protrusion 24 fixed to the suction pipe 10.

이와 같이 구성된 본 고안에 따른 실시예의 작용을 설명하면, 펌핑작용이 개시되면 펌프 내부와 외부의 압력차에 의해 수원의 물이 커버부(21)를 밀고 펌프 내부로 유입되며, 이 때, 커버부(21)는 연결부(23)를 중심으로 회전하면서 흡입구(11)를 개방시키게 된다.Referring to the operation of the embodiment according to the present invention configured as described above, when the pumping action is initiated by the pressure difference between the inside and outside of the pump, the water of the source pushes the cover portion 21 and flows into the pump. 21 rotates around the connecting portion 23 to open the suction port 11.

반대로, 펌핑작용이 정지되면 밸브(20)의 자체 탄성력에 의해 연결부(23)는 커버부(11)를 오픈시와 반대 방향으로 회전시키면서 흡입구(11)를 폐쇄시킨다.On the contrary, when the pumping action is stopped, the connection part 23 closes the inlet port 11 while rotating the cover part 11 in the opposite direction to the opening time by the elastic force of the valve 20.

따라서, 흡입구(11)를 개폐시키기 위한 커버부(21)의 회전을 안내하는 연결부(23)의 폭이 종래보다 넓어지기 때문에 커버부(21)를 폐쇄시키기 위한 연결부(23)의 탄성력이 증대되어 커버부(21)가 좀 더 빠른 시간내에 복원되면서 흡입구(11)를 폐쇄시키므로 펌프 내부의 물이 누수되지 않게 된다.Therefore, since the width of the connecting portion 23 for guiding the rotation of the cover portion 21 for opening and closing the suction port 11 becomes wider than before, the elastic force of the connecting portion 23 for closing the cover portion 21 is increased. The cover 21 is closed in a faster time, thereby closing the inlet 11 so that water inside the pump is not leaked.

이상에서 살펴본 바와 같이, 본 고안에 따른 흡입구 밸브에 의하면, 밸브의 커버부가 신속하게 복원되면서 흡입구를 폐쇄시켜 펌프 내부의 물이 누수되지 않기 때문에 결과적으로 다음 펌핑작동이 정상적으로 수행되어 펌프 내부의 압력 유지를 위해 별도의 압력탱크를 사용하지 않아도 되므로 비용을 절감할 수 있는 효과가 있다.As described above, according to the inlet valve according to the present invention, since the cover portion of the valve is quickly restored and the inlet port is not leaked, the water inside the pump is not leaked. As a result, the next pumping operation is normally performed to maintain the pressure inside the pump. There is no need to use a separate pressure tank to reduce the cost.
