본 발명은 쿠션 체크밸브에 관한 것으로, 더욱 상세하게는 구조가 간단함과 아울러 설치공간을 적게 차지하면서도 펌프의 작동 중지시 발생되는 수격현상을 감소시키기 위하여 밸브몸체의 내부에 연통홈이 형성된 실린더를 설치하고, 상기 실린더에서 전,후진되는 디스크부재를 설치한 쿠션 체크밸브에 관한 것이다.The present invention relates to a cushion check valve, and more particularly, a cylinder having a communication groove formed inside the valve body in order to reduce the water hammer occurring when the pump is stopped while the structure is simple and occupies little installation space. The present invention relates to a cushion check valve provided with a disk member that is forward and backward from the cylinder.

일반적으로 취수장, 정수장 및 가압장과 관로 등과 같은 수로에는 상기 수로를 통과한 물이 역류되는 것을 방지하기 위해 일방향으로 개폐가 이루어지도록 구성된 체크밸브가 설치되어 있다.In general, a check valve configured to open and close in one direction is installed in a water channel such as a water intake, a water purification plant, a pressurized plant, and a pipeline to prevent backflow of water passing through the channel.

도 1 및 도 2는 종래에 따른 체크밸브의 일실시예를 나타낸 도면이다.1 and 2 is a view showing an embodiment of a conventional check valve.

도시된 바와 같이, 체크밸브(100)는 내부에 유로를 가지며 양측에는 유입구(1a) 및 유출구(1b)를 구비한 밸브몸체(1)와, 상기 밸브몸체(1)를 관통하는 축(1c)과, 상기 축(1c)의 외경에 끼워지는 로드(1d)와, 상기 로드(1d)에 부착 고정As shown, the check valve 100 has a flow path therein and a valve body 1 having an inlet port 1a and an outlet port 1b on both sides thereof, and a shaft 1c penetrating the valve body 1. And a rod 1d fitted to the outer diameter of the shaft 1c, and fixed to the rod 1d.

되어 축(1c)과 함께 회동하며 유입구(1a)를 개폐시키는 디스크(2) 및 상기 밸브몸체(1)의 외부로 돌출되어 있는 상기 축(1c)의 외경에 설치되는 웨이트(2a) 및 유압실린더(2b)로 구성한다.Weight 2a and a hydraulic cylinder which are rotated together with the shaft 1c and installed on the outer diameter of the disk 2 for opening and closing the inlet port 1a and the shaft 1c protruding out of the valve body 1.

상기 디스크 부재(40)는 상기 실린더(30)의 개방면 측으로 피스톤부(41)가 결합되고, 상기 피스톤부(41)의 반대면 측에 원판체(42)가 형성되어 상기 밸브시트부(11)와의 접촉에 따라 유로를 개폐하는 것이다.The disk member 40 is coupled to the piston portion 41 to the open surface side of the cylinder 30, the disk body 42 is formed on the opposite surface side of the piston portion 41 is the valve seat portion 11 The opening and closing of the flow path in accordance with the contact.

또한, 상기 밸브시트부(11)에는 패킹(50)이 결합되어 있다.In addition, the packing 50 is coupled to the valve seat portion 11.

또한, 상기 디스크 부재(40)의 외주면은 상기 제1,2 밸브몸체(10)(20) 중의 어느 타측, 더 자세히는 제2 밸브몸체(20)의 내주면에 설치되어진 안내리브(21)를 따라 안내되도록 함으로서, 디스크 부재(40)의 전,후진 동작시 흔들림 등을 방지할 수 있다.In addition, the outer circumferential surface of the disk member 40 is along the guide rib 21 provided on any other side of the first and second valve bodies 10 and 20, more specifically, on the inner circumferential surface of the second valve body 20. By guiding, it is possible to prevent shaking and the like during the forward and backward operations of the disk member 40.

또한, 상기 제1,2 밸브몸체(10)(20)의 어느 일측에 연결된 펌프(200)에 의해 펌프(200)가 작동되면, 실린더(30)의 연통홈(31)으로 유입된 유체에 의해 상기 디스크 부재(40)의 피스톤부(41)가 전진하여 유로를 개방하고, 상기 펌프(200)가 중지되면, 상기 디스크 부재(40)의 원판체(42)에 가해지는 압력에 의해 유로가 폐쇄되도록 하는 것이다.In addition, when the pump 200 is operated by the pump 200 connected to one side of the first and second valve bodies 10 and 20, by the fluid introduced into the communication groove 31 of the cylinder 30. When the piston part 41 of the disk member 40 moves forward to open the flow path, and the pump 200 is stopped, the flow path is closed by the pressure applied to the disc 42 of the disk member 40. It is to be possible.

그리고, 상기 실린더(30)와 제1 밸브몸체(10)를 연결하는 배관라인 상에 유량 조절밸브(60)를 설치하여 상기 디스크 부재(40)가 유체를 차단하는 경우에 실린더(30)의 내부의 유체가 유량 조절밸브(60)의 통해 다시 제1밸브몸체(10) 측으로 유동되도록 하며, 이과정에서 유량 조절밸브(60)의 조절에 의해 디스크 부재(40)가 폐쇄되는 속도를 조절하게 되는 것이다.In addition, the flow rate control valve 60 is installed on a pipe line connecting the cylinder 30 and the first valve body 10 so that the disc member 40 blocks the fluid in the interior of the cylinder 30. Of the fluid flows back to the first valve body 10 through the flow control valve 60, in this process to control the speed of the disk member 40 is closed by the control of the flow control valve 60 will be.

한편, 미설명 부호 70은 실린더의 개방면 측에 고정되어진 부싱을 나타내고 있다.On the other hand, reference numeral 70 denotes a bushing fixed to the open face side of the cylinder.

상기와 같이 구성된 본 발명의 쿠션 체크밸브(100)는, 펌프(200)가 동작하게 되면 제1 밸브몸체(10)에서 제2 밸브몸체(20)로 유체가 유동되는데, 상기 제1 밸브몸체(10) 측의 압력이 상승함과 아울러 실린더(30)의 연통홈(31)을 통해 유체가 유입되어 상기 디스크 부재(40)를 제2 밸브몸체(20) 측으로 이동시키게 된다.In the cushion check valve 100 of the present invention configured as described above, when the pump 200 operates, the fluid flows from the first valve body 10 to the second valve body 20, wherein the first valve body ( The pressure of 10) increases and fluid flows through the communication groove 31 of the cylinder 30 to move the disk member 40 toward the second valve body 20.

이때 상기 디스크 부재(40)의 원판체(42)는 제2 밸브몸체(20)의 내주면에 형성된 안내리브(21)를 따라 이동되면서, 제1 밸브몸체(10)의 밸브시트부(11)에서 디스크 부재(40)의 원판체(42)가 이격되면서 유체는 제1 밸브몸체(10)에서 제2 밸브몸체(20) 측으로 이동된다. At this time, the disk 42 of the disk member 40 is moved along the guide rib 21 formed on the inner circumferential surface of the second valve body 20, the valve seat portion 11 of the first valve body 10 As the disc body 42 of the disc member 40 is spaced apart, the fluid is moved from the first valve body 10 to the second valve body 20 side.

즉, 제1 밸브몸체(10)와 제2 밸브몸체(20)의 압력이 같아지면서 유체가 제1 밸브몸체(10)에서 제2 밸브몸체(20) 측으로 이동된다.That is, while the pressure of the first valve body 10 and the second valve body 20 are equal, the fluid is moved from the first valve body 10 to the second valve body 20 side.

한편, 펌프(200)의 동작이 정지되면 제2 밸브몸체(20) 측의 압력이 상승되면서 디스크 부재(40)의 원판체(42)에 압력을 가하고, 상기 디스크 부재(40)의 피스 톤부(41)가 실린더(30)에서 전진하면서 실린더(30) 내부에 충진되어져 있던 유체가 연통홈(31)에서 배출되면서 디스크 부재(40)의 원판체(42)는 제1 밸브몸체(10)의 밸브시트부(11)에 접촉되면서 유체의 흐름은 정지하게 되는데, 이때 탄성부재(43)의 탄성력에 의해서도 유체의 차단이 가능하게 된다.On the other hand, when the operation of the pump 200 is stopped, the pressure on the disk body 42 of the disk member 40 is increased while the pressure on the second valve body 20 side is increased, and the piston part of the disk member 40 ( As the 41 is advanced from the cylinder 30, the fluid filled in the cylinder 30 is discharged from the communication groove 31, and the disc body 42 of the disc member 40 is the valve of the first valve body 10. The flow of the fluid is stopped while contacting the seat portion 11, at this time, the fluid can be blocked even by the elastic force of the elastic member 43.

또한, 디스크 부재(40)의 폐쇄되는 속도를 조절하기 위해서는 유량조절밸브(60)를 조절하여 실린더(30)의 내부에서 배출되는 유체의 양을 조절함으로서 가능하게 된다.In addition, in order to adjust the closing speed of the disk member 40, it is possible by adjusting the flow rate control valve 60 to adjust the amount of fluid discharged from the interior of the cylinder (30).

즉, 유체는 제1 밸브몸체(10)에서 제2 밸브몸체(20) 측으로 이동되며, 그 반대로는 유체의 흐름을 차단하여 체크밸브의 기능을 수행하게 된다.That is, the fluid is moved from the first valve body 10 to the second valve body 20 side, and vice versa by blocking the flow of the fluid to perform the function of the check valve.
