The first opening / closing valve 60 disposed in the diaphragm 50 and the first mounting chamber 21 of the left panel 20 to open and close the left inlet 12 of the suction passage 11 of the center member 10. ) And a second opening / closing disposed in the second mounting chamber 23 of the left panel 20 to open and close the second communication hole 24 communicating with the first pumping chamber 31 of the left diaphragm 30. In communication with the valve 70, the third open / close valve 70 for opening and closing the right inlet 13 of the suction passage 11 of the center member 10, and the second pumping chamber 51 of the right diaphragm 50. Be The fourth communication is composed of the fourth on-off valve 80 for opening and closing the hole (44).

상기 좌측 패널(20)은 제 1 개폐밸브(60)가 장착되는 제 1 장착실(21)에 제 1 소통구멍(22)이 형성되어, 상기 제 1 소통구멍(22)에 의해 좌측 다이어프램(30)의 제 1 펌핑실(31)과 센터 부재(10)의 흡입구멍(11)이 연통되고, 제 2 개폐밸브(70)가 장착되는 제 2 장착실(23)에 제 2 소통구멍(24)이 형성되어, 상기 제 2 소통구멍(24)에 의해 좌측 다이어프램(30)의 펌핑실(31)과 센터 부재(10)의 배출통로(15)가 연통된다.The left panel 20 has a first communication hole 22 formed in the first mounting chamber 21 in which the first opening / closing valve 60 is mounted, and the left diaphragm 30 is formed by the first communication hole 22. The second pumping chamber 24 is connected to the second pumping chamber 31 in which the first pumping chamber 31 and the suction hole 11 of the center member 10 communicate with each other, and the second opening / closing valve 70 is mounted. The second communication hole 24 communicates with the pumping chamber 31 of the left diaphragm 30 and the discharge passage 15 of the center member 10.

상기 우측 패널(40)은 제 3 개폐밸브(80)가 장착되는 제 3 장착실(41)에 제 3 소통구멍(42)이 형성되어, 상기 제 3 소통구멍(42)에 의해 우측 다이어프램(50)의 펌핑실(51)과 센터 부재(10)의 흡입통로(11)가 연통되고, 제 4 개폐밸브(90)가 장착되는 제 4 장착실(43)에 제 4 소통구멍(44)이 형성되어, 상기 제 4 소통구멍(44)에 의해 우측 다이어프램(50)의 제 2 펌핑실(51)과 센터 부재(10)의 배출통로(15)가 연통된다.The right panel 40 has a third communication hole 42 formed in the third mounting chamber 41 in which the third opening / closing valve 80 is mounted, and the right diaphragm 50 is formed by the third communication hole 42. The fourth communication hole 44 is formed in the fourth mounting chamber 43 in which the pumping chamber 51 and the suction passage 11 of the center member 10 communicate with each other. Thus, the second pumping chamber 51 of the right diaphragm 50 and the discharge passage 15 of the center member 10 communicate with each other by the fourth communication hole 44.

상기 제 1 내지 제 4 개폐밸브(60, 70, 80, 90)는 구성이 동일하지만, 제 1 개폐밸브(60)와 제 2 개폐밸브(70)가 서로 반대 방향으로 배치되고, 제 3 개폐밸브 (80)와 제 4 개폐밸브(90)가 서로 반대 방향으로 배치된다.The first to fourth on-off valves 60, 70, 80, and 90 have the same configuration, but the first on-off valve 60 and the second on-off valve 70 are disposed in opposite directions, and the third on-off valve 80 and the fourth on-off valve 90 are arranged in opposite directions to each other.

도 2를 참조하면, 상기 제 1 개폐밸브(60)는 실리콘 또는 고무로 이루어지며, 환형의 장착부(61)와 개폐작용을 하는 원판부(62)가 만곡되게 굴곡되는 연결부(63)에 의해 연결된다.Referring to FIG. 2, the first opening / closing valve 60 is made of silicon or rubber and connected by an annular mounting portion 61 and a connecting portion 63 in which a disc portion 62 that opens and closes is curved. do.

이것에 의해, 만곡되게 굴곡된 연결부(63)의 형상에 의해 연결부(63)가 텐션을 갖게 되므로서, 도 1에 도시된 것처럼, 상기 연결부(63)의 텐션력에 의해 원판부(62)가 흡입통로(11)의 좌측 유입구(12) 둘레에 수밀되게 압착되어, 좌측 다이어프램(30) 및 우측 다이어프램(50)이 작동되지 않을 때, 흡입통로(11)에 채워진 유체가 좌측 유입구(12)를 통해 제 1 펌핑실(31)로 유입되지 않고, 제 1 펌핑실(31)에 채워진 유체가 흡입통로(11)로 역류되는 것을 방지할 수 있다.As a result, the connecting portion 63 is tensioned by the shape of the bent portion 63 curved, and as shown in FIG. 1, the disc portion 62 is formed by the tension of the connecting portion 63. When the left diaphragm 30 and the right diaphragm 50 are not actuated by watertight compression around the left inlet 12 of the suction passage 11, the fluid filled in the suction passage 11 may pass through the left inlet 12. It is possible to prevent the fluid filled in the first pumping chamber 31 from flowing back into the suction passage 11 without being introduced into the first pumping chamber 31 through the pump.

나머지 제 2 내지 제 4 개페밸브(70, 80, 90) 또한 제 1 개페밸브(60)와 같이 좌측 다이어프램(30) 및 우측 다이어프램(50)이 작동하지 않을 때, 흡입통로(11) 또는 토출통로(15)에서 유체의 누수를 방지할 수 있고, 유체의 역류를 방지할 수 있다.When the left diaphragm 30 and the right diaphragm 50 do not operate like the first open valves 70, 80, 90 and the first open valves 60, the suction passage 11 or the discharge passage, respectively. At 15, leakage of the fluid can be prevented, and backflow of the fluid can be prevented.

상기와 같이 구성된 본 발명에 따른 다이어프램 펌프의 작동을 도 3 및 도 4를 참조하여 설명하기로 한다.The operation of the diaphragm pump according to the present invention configured as described above will be described with reference to FIGS. 3 and 4.

도 3에 도시된 바와같이, 좌측 다이어프램(30)에 의해 제 1 펌핑실(31)이 압축될 때, 제 1 펌핑실(31)의 압축압력에 의해 제 2 소통구멍(24)을 막고있던 제 2 개폐밸브(70)가 개방되어 제 1 펌핑실(31)에 있던 유체가 제 2 소통구멍(24)을 통해 토출통로(15)로 공급되고, 상기 토출통로(15)을 통해 외부로 토출된다. 이때, 제 1 개폐밸브(60)가 흡입통로(11)의 좌측 유입구(12)를 막고 있어, 제 1 개폐밸브(60)에 의해 제 1 펌핑실(31)의 압축 압력이 흡입통로(11)로 전달되지 않게 된다.As shown in FIG. 3, when the first pumping chamber 31 is compressed by the left diaphragm 30, the second communication hole 24 is blocked by the compression pressure of the first pumping chamber 31. 2 The on-off valve 70 is opened so that the fluid in the first pumping chamber 31 is supplied to the discharge passage 15 through the second communication hole 24 and discharged to the outside through the discharge passage 15. . At this time, the first opening / closing valve 60 blocks the left inlet 12 of the suction passage 11, so that the compression pressure of the first pumping chamber 31 is absorbed by the first opening / closing valve 60. It will not be delivered to.

그리고, 상기 좌측 다이어프램(30)에 의해 제 1 펌핑실(31)이 압출될 때, 우측 다이어프램(50)에 의해 제 2 펌핑실(51)이 확장된다. 이때, 제 2 펌핑실(51)의 흡입력에 의해 흡입통로(11)의 우측 유입구(13)를 막고 있던 제 3 개페밸브(80)가 개방되고, 상기 흡입통로(11)를 통해 제 2 펌핑실(51)로 유체가 흡입되고, 제 4 개폐밸브(90)가 제 4 소통구멍(44)을 차단하므로서, 제 2 펌핑실(51)의 흡입력이 토출구멍(15)으로 전달되지 않게 된다.When the first pumping chamber 31 is extruded by the left diaphragm 30, the second pumping chamber 51 is extended by the right diaphragm 50. At this time, the third open valve 80 which is blocking the right inlet 13 of the suction passage 11 is opened by the suction force of the second pumping chamber 51, and the second pumping chamber is opened through the suction passage 11. Fluid is sucked into the 51 and the fourth open / close valve 90 blocks the fourth communication hole 44 so that the suction force of the second pumping chamber 51 is not transmitted to the discharge hole 15.

도 4에 도시된 바와같이, 좌측 다이어프램(30)에 의해 제 1 펌핑실(31)이 확장되고, 우측 다이어프램(50)에 의해 제 2 펌핑실(51)이 압축될 때, 제 1 개폐밸브(60)가 개방되고 제 2 개폐밸브(70)가 닫히게 되어 제 1 펌핑실(51)로 유체가 흡입되는 한편, 제 3 개폐밸브(80)가 닫히고 제 4 개폐밸브(90)가 개방되므로서, 제 2 펌핑실(51)의 유체가 토출구멍(15)을 통해 토출된다. As shown in FIG. 4, when the first pumping chamber 31 is expanded by the left diaphragm 30 and the second pumping chamber 51 is compressed by the right diaphragm 50, the first opening / closing valve ( 60 is opened and the second on-off valve 70 is closed so that fluid is sucked into the first pumping chamber 51, while the third on-off valve 80 is closed and the fourth on-off valve 90 is opened, The fluid of the second pumping chamber 51 is discharged through the discharge hole 15.

위에서 설명한 바와같이, 본 발명에 따른 다이어프램 펌프는 좌우측 다이어프램이 번갈아 압축 및 확장되므로서, 흡입구멍과 토출구멍에서 연속적으로 흡입 및 토출작용이 이루어지며, 유체의 흡입 및 토출압력손실이 발생하지 않고, 유체의 역류를 방지할 수 있는 효과가 있다.As described above, in the diaphragm pump according to the present invention, since the left and right diaphragms are alternately compressed and expanded, suction and discharge are continuously performed at the suction hole and the discharge hole, and the suction and discharge pressure loss of the fluid does not occur. There is an effect that can prevent the back flow of the fluid.
