Description

수동개폐식 체크밸브Manual Opening Check Valve

본 고안은 수동개폐식 체크밸브에 관한 것으로, 더욱 구체적으로는 유체의 역류방지용으로 사용되는 체크밸브의 디스크가 장시간 동안 열린상태로 작동되어 고착될 경우 수동조작으로 디스크를 회전시켜 체크밸브로 사용가능하고 체크밸브의 개폐상태를 외부에서 식별 가능도록하여 유체의 흐름을 차단하는 일반적인 밸브로서도 사용할 수 있도록 한 것이다.The present invention relates to a manual open / close check valve, and more specifically, when a disk of a check valve used for preventing a backflow of a fluid is held open for a long time and is stuck, it can be used as a check valve by rotating the disk by manual operation. The open / closed state of the check valve can be identified from the outside so that it can be used as a general valve to block the flow of fluid.

일반적으로 유체설비중 공기라인이나 급배수관등에 역류를 방지하기 위해 체크밸브를 사용하게 되나, 체크밸브의 장시간동안 사용으로 체크밸브의 디스크가 유체내의 이물질이나 녹등에 의한 부식으로 열린상태에서 고착되어 공기나 물의 역류를 방지하지 못해 대형설비사고의 원인을 제공하게 되며, 체크밸브의 개폐상태를 외부에서 확인할수 없게 되어 체크밸브 내부를 수리하는 잦은 점검 및 보수작업을 감수해야만 되는 것이다.In general, check valves are used to prevent backflow into air lines or water supply pipes in fluid installations.However, the disks of check valves are stuck in the open state due to foreign matter or rust in the fluid due to long periods of use. It can not prevent the backflow of herbs and cause the cause of large-scale equipment accidents, and the open / closed state of the check valve cannot be confirmed from the outside, so it is necessary to take frequent checks and repairs to repair the inside of the check valve.

본 고안은 상기와 같은 제반 문제점을 감안하여 이를 해소할 수 잇도록 한 것으로, 유체의 역류방지용으로 사용되는 체크밸브의 디스크가 오랜동작으로 유체내의 이물질 또는 녹에 의한 부식됨으로 인해 유체를 완전하게 차단하지 못하는 경우에는 수동작에 의해 체크밸브로서 작동되고, 체크밸브의 개폐상태를 외부에서 식별가능하도록 하여 일반적인 밸브로서도 사용가능한 수동개폐식 체크밸브를 제공하는데 그 목적이 있는 것이다.The present invention is to solve this problem in consideration of the above problems, the disk of the check valve used to prevent the backflow of fluid is completely blocked by the foreign matter or rust corrosion in the fluid due to long operation If not, the purpose of the present invention is to provide a manual open / close check valve which is operated as a check valve by manual operation and makes the open / close state of the check valve identifiable from the outside.

상기와 같은 목적을 달성하기 위한 본 고안의 특징은 유체의 역류방지용으로 사용되는 체크밸브의 상부관에 레버의 일단부가 회동가능하게 설치되고 이의 타단에는 체크밸브를 개폐시키는 디스크가 설치되어 유체의 역류를 방지할 수 있도록한 것에 있어서, 상기 레버의 타측 끝단에 힌지 결합되고 타측은 체크밸브의 외부로 돌출 설치된 수동레버와, 상기 수동레버를 정지시키기 위하여 체크밸브의 외측둘레면 일측에 설치된 스토퍼로 이루어진 것이다.A feature of the present invention for achieving the above object is that one end of the lever is rotatably installed on the upper tube of the check valve used for preventing the back flow of the fluid, and the other end of the disk is installed to open and close the check valve, the reverse flow of the fluid In order to prevent the, the hinge is coupled to the other end of the lever and the other side consists of a manual lever protruding out of the check valve, and a stopper provided on one side of the outer circumferential surface of the check valve to stop the manual lever will be.

제1도는 본 고안에 의한 체크밸브의 단면도.1 is a cross-sectional view of the check valve according to the present invention.

이하, 본 고안에 의한 수동개폐식 체크밸브를 첨부도면을 참조하여 구체적으로 설명한다.Hereinafter, with reference to the accompanying drawings, the manual opening and closing check valve according to the present invention will be described in detail.

공기나 물등의 유체 역류방지용으로 사용되는 체크밸브에서의 디스크를 수동작에 의해 개폐시킬 수 있도록 체크밸브를 형성함에 있어서, 뚜껑(7)이 착탈식으로 상단부에 장착된 체크밸브(1)의 상부관(2) 내측에 일단부가 힌지고정된 레버(3)의 타측이 유체를 차단하는 디스크(4)의 이면중앙에 일체형으로 고정하고, 상기 레버(3)의 타측에는 디스크(4)를 개폐시키는 금속재의 수동레버(5)의 일단부를 회동가능하게 고정하되, 수동레버(5)의 타단부는 상부관(2) 외측으로 노출되게 형성하고, 수동레버(5)와 상부관(2) 사이에서 유체의 노출됨을 방지하는 합성수지재와 금속재가 교대로 형성된 나사산의 형상으로 된 패킹(8)이 장착되며, 상기 패킹(8)의 일측에는 디스크(4)의 폐쇄시 수동레버(5)의 유동을 제거하는 스토퍼(6)가 상부관(2) 외측 둘레면 일측에 형성되며, 체크밸브(1)의 출구측 곡관부(9)에는 디스크(4)와 수동레버(5)의 파손됨이 방지되도록 디스크(4)의 과대 열림을 방지하는 디스크 받침대(10)가 장착된 것이다.In forming a check valve to open and close a disk in a check valve used for preventing a fluid backflow such as air or water by manual operation, the upper pipe of the check valve 1 detachably attached to the upper end of the lid 7 is provided. (2) The other side of the lever 3, one end of which is fixed to the inside, is integrally fixed to the center of the rear surface of the disk 4 to block the fluid, and the other side of the lever 3 of the metal material for opening and closing the disk 4 One end of the manual lever 5 is rotatably fixed, the other end of the manual lever 5 is formed to be exposed to the outside of the upper tube (2), the fluid between the manual lever (5) and the upper tube (2) A packing 8 having a threaded shape in which synthetic resin material and a metal material are alternately formed to prevent exposing is mounted, and one side of the packing 8 removes the flow of the manual lever 5 when the disc 4 is closed. Stopper 6 is formed on one side of the outer peripheral surface of the upper tube (2) On the outlet side curved portion 9 of the check valve 1, the disk support 10 is installed to prevent the disk 4 from being excessively opened to prevent the disk 4 and the manual lever 5 from being damaged. .

상기와 같이 구성된 본 고안에 의한 체크밸브는 발전설비중 에어라인이나 급배수관등에서 유체의 역류방지용으로 설치되는 체크밸브(1)의 입구측을 통해 유입되는 유체의 유속에 의해 디스크(4)는 가상선을 도시된 바와 같이, 디스크(4)이면에 고정된 레버(3)가 상부관(2)일측의 힌지점을 중심으로 하여 회동함에 따라 디스크(4) 또한 회동하게 되어 출구측 곡관부(9)에 형성된 디스크 받침대(10)에 접촉되어지는 것이고, 이때 수동레버(5)는 화살표시 방향으로 상승하게 되어 상부관(2)외측으로 노출되므로 사용자는 체크밸브(1)의 디스크(4)가 열려있다는 것을 확인할 수 있는 것이다.The check valve according to the present invention configured as described above has a virtual disk 4 due to the flow rate of the fluid flowing through the inlet side of the check valve 1 which is installed for preventing the backflow of the fluid in the air line or the water supply and drainage pipe of the power generation equipment. As the line is shown, as the lever 3 fixed to the disk 4 is rotated around the hinge point of one side of the upper pipe 2, the disk 4 is also rotated, so that the outlet side curved pipe portion 9 ), The manual lever (5) is raised in the direction of the arrow and is exposed to the outside of the upper pipe (2), so that the disc (4) of the check valve (1) You can see that it is open.

한편 체크밸브(1)내에 유체의 유입이 정지되면 디스크(4)는 자중에 의해 제 위치에 복귀하게 되어 수동레버(5)는 레버(3)가 일단부를 힌지점으로 하여 회동하게 되므로 체크밸브(1)내에 복귀되는 것이며, 이때 사용자는 체크밸브(1)의 디스크(4)가 닫혀있다는 것을 확인하게 되는 것이다.On the other hand, when the inflow of fluid in the check valve 1 is stopped, the disk 4 returns to its position by its own weight, and the manual lever 5 rotates the lever 3 at one end as a hinge point. 1), the user will confirm that the disk 4 of the check valve 1 is closed.

또한 체크밸브(1)의 장시간 사용으로 디스크(4)가 유체내의 이물질 또는 녹등의 부식에 의해 열린 상태에서 고착되어 유속이 정지상태에서도 디스크(4)가 완전하게 닫혀지지 않을 때 수동레버(5)에 강한 힘으로 외력을 가하여, 체크밸브(1)의 디스크(4)를 폐쇄시키는 것이며, 그리고 체크밸브(1)의 입·출구측에 연통되는 일반적인 밸브에 문제점이 발생되어 유체가 누출되는경우에 수동레버(5)를 체크밸브(1) 내측으로 밀어넣어 디스크(4)를 폐쇄시킨 후 상부관(2) 외주연 일측에 형성된 스토퍼(6)의 고정나사(11)로서 고정함에 따라 일반적인 밸브기능으로의 겸용사용이 가능한 것이다.In addition, when the disc 4 is stuck in the open state due to the foreign matter or rust in the fluid due to the long time use of the check valve 1, the disc 4 is not completely closed even when the flow rate is stopped. When the external valve is applied with a strong force to close the disc 4 of the check valve 1, and a problem occurs in a general valve communicating with the inlet / outlet side of the check valve 1 and fluid leaks. Push the manual lever 5 into the check valve 1 to close the disc 4, and then fix it as a fixing screw 11 of the stopper 6 formed on one side of the outer circumference of the upper pipe 2, thereby providing a general valve function. It is possible to use as a combined.

이상에서와 같이 본 고안에 의한 수동개폐식 체크밸브는 유체가 역류되기 쉽거나 장시간 동안 작동으로 체크밸브의 디스크가 개방된 상태에서 유체속의 이물질 또는 녹등의 부식으로 고착되는 경우 디스크의 불완전한 개폐동작으로 설비 사고 발생 방지와, 체크밸브의 개페동작을 외부에서 육안으로 식별할 수 없어 발생되는 체크밸브의 잦은 수리점검으로 인한 인건비 상승됨을 방지할 수가 있는 것이다.As described above, the manual open / close check valve according to the present invention is equipped with an incomplete opening / closing operation of the disk when the fluid is easily reversed or stuck for a long time due to corrosion of foreign matter or rust in the fluid while the disk of the check valve is opened. It is possible to prevent accidents and to increase labor costs due to frequent checks and checks of check valves, which cannot be visually recognized from the outside.
