As an excerpt perspective view etc. which show the cams 8 and 9 which become to be described, the structure of this invention is demonstrated below with these figures in detail.

즉, 본 발명의 콘트롤 체크 밸브(1)는 밸브 몸체(2)상에 형성되는 유체통수공(3)과 직교하는 방향에서 축(4a) 결합되는 핸들(4)의 하단에 웜(5)을 형성하고, 상기 웜(5)에 직교되는 방향에서 기어물림되는 대응 웜훨(6)을 축핀(7)상에 자유회전 가능하게 결합한다.That is, the control check valve 1 of the present invention has a worm 5 at the lower end of the handle 4 coupled to the shaft 4a in a direction orthogonal to the fluid passage 3 formed on the valve body 2. And a corresponding worm wheel 6 geared in a direction orthogonal to the worm 5 so as to be freely rotatable on the shaft pin 7.

상기 축핀(7)상에 결합된 웜훨(6) 양측으로는 돌출 원호형 캠(8)을 형성하고, 이에 대응하는 돌출 원호형 캠(9)을 축핀(7)에 결합되는 연결레버(10) 양측으로 형성하여 상호 소정 각도 범위내에서는 연결레버(10)가 정역방향으로 각운동할 수 있도록 한다.The connecting lever 10 which forms a protruding arc cam 8 on both sides of the worm wheel 6 coupled to the shaft pin 7, and the protruding arc cam 9 corresponding thereto is coupled to the shaft pin 7. Formed on both sides to allow the connecting lever 10 to angular movement in the forward and reverse directions within a predetermined angle range.

이를 위하여 상기 웜훨(6)에 형성되는 돌출 원호형 캠(8)의 각도는 약 120°정도로 하고, 대응하는 연결레버(10)상의 돌출 원호형 캠(9)의 각도는 약 170°정도로 한다.To this end, the angle of the protruding arc cam 8 formed in the worm wheel 6 is about 120 degrees, and the angle of the protruding arc cam 9 on the corresponding connecting lever 10 is about 170 degrees.

상기 연결레버(10)의 타단은 유체통수공(3)을 개폐 작동하는 밸브시트(11)가 핀(12) 연결된다.The other end of the connecting lever 10 is the valve seat 11 for opening and closing the fluid flow hole 3 is connected to the pin (12).

도면중의 부호 13은 테프론 등과 같은 기밀유지수단, 14는 핸들 설치용 고정캡을 도시한 것이다.In the drawings, reference numeral 13 denotes an airtight holding means such as Teflon, and 14 shows a fixing cap for installing a handle.

상기와 같이 구성될 수 있는 본 발명의 콘트롤 체크 밸브(1)는 일반적으로 체크 밸브의 기능을 요할 경우에는 핸들(4)을 중립 상태로 두고, 강제적으로 개방이나 폐쇄를 원할 시에는 개방, 폐쇄위치로 핸들(4)을 전환시켜 밸브(1)를 사용자가 원하는 위치로 설정하여 유체의 공급여부를 단속할 수 있는 것인바, 이의 작용 등에 대하여 이하에 보다 상세히 설명키로 한다.The control check valve 1 of the present invention, which can be configured as described above, generally requires the handle 4 to be in a neutral state when a function of the check valve is required, and an open or closed position when a forced opening or closing is desired. By switching the handle 4 to the furnace to set the valve 1 to a desired position to control the supply of the fluid, its action and the like will be described in more detail below.

밸브(1)의 핸들(4)을 중립상태에 두게 되면, 핸들(4)의 축(4a) 하단부에 형성된 웜(5)와 축핀(7)에 설치된 웜훨(6)는 상호 기어물림 상태에 있게 된다.(도 4b 참조)When the handle 4 of the valve 1 is placed in a neutral state, the worm 5 formed on the lower end of the shaft 4a of the handle 4 and the worm wheel 6 installed on the shaft pin 7 are in a mutually engaged state. (See FIG. 4B).

이때 연결레버(10)와 연결되어 유체통수공(3)을 폐쇄하고 있는 밸브시트(11)는 유체 압력에 따라 유체통수공(3)상에서 각운동하여 개폐가 자동으로 이루어지게되어 일반적인 체크 밸브와 동일한 상태로 기능을 하게 되는 바, 이는 상기 연결레버(10)에 형성된 캠(9)이 웜훨(6)에 형성된 캠(8)과 이루는 각도 차이에 의해 가능한 것으로서, 연결레버(10)에 형성된 돌출 원호형 캠(9)은 약 170°정도로 형성되어 있고, 웜훨(6)에 형성된 돌출 원호형 캠(8)은 약 120°정도이기 때문에 연결레버(10)는 개방 방향으로 약 70°정도는 웜휠(6)에 형성된 돌출 원호형 캠(8)의 방해를 받지 않고 자유 각운동 개폐가 이루어질 수 있는 것이다.In this case, the valve seat 11 connected to the connecting lever 10 to close the fluid passage 3 is angularly moved on the fluid passage 3 according to the fluid pressure, so that the valve seat 11 is opened and closed automatically. The same function as the bar, which is possible by the angle difference between the cam 9 formed in the connecting lever 10 and the cam 8 formed in the worm wheel 6, the protrusion formed in the connecting lever 10 The arc cam (9) is formed at about 170 degrees, and since the protruding arc cam (8) formed at the worm wheel (6) is about 120 degrees, the connecting lever (10) is about 70 degrees in the opening direction. The free angular motion opening and closing can be made without being disturbed by the protruding arc cam 8 formed in (6).

그리고 사용자가 밸브(1)를 강제적으로 개폐코자 할 시는 핸들(4)을 개방 또는 폐쇄상태로 전환시키면 밸브시트(11)가 유체통수공(3)으로부터 개방되거나 폐쇄될 수 있는 바, 이는 상기 핸들(4)의 축(4a) 하단에 형성된 웜(5)이 축핀(7)에 설치된 웜훨(6)과 기어물림되어 있어 핸들(4)을 개방 방향 또는 폐쇄 방향으로 회전을 시키면, 웜(5)에 의해 축핀(7)상의 웜훨(6)도 회전을 하면서 이에 형성된 캠(8)이 연결레버(10)상의 대응 캠(9)과 걸림되어 연결레버(10)를 개방 방향(도 4c 참조) 또는 폐쇄 방향(도 4a 참조)으로 각운동을 시키게 되므로 연결레버(10)와 연결된 밸브시트(11)가 유체통수공(3)을 개방하거나 폐쇄시킬 수 있는 것이다.And when the user forcibly opens and closes the valve 1, when the handle 4 is switched to the open or closed state, the valve seat 11 can be opened or closed from the fluid passage 3, which is the The worm 5 formed at the lower end of the shaft 4a of the handle 4 is meshed with the worm wheel 6 installed on the shaft pin 7 so that the handle 4 is rotated in the open or closed direction. The worm wheel 6 on the shaft pin 7 also rotates, and the cam 8 formed thereon is engaged with the corresponding cam 9 on the connecting lever 10 to open the connecting lever 10 in an opening direction (see FIG. 4C). Alternatively, since the angular movement is performed in the closing direction (see FIG. 4A), the valve seat 11 connected to the connection lever 10 may open or close the fluid passage 3.

이상에서 상세히 살펴 본 바와 같이 본 발명에서 제공하는 콘트롤 체크 밸브(1)는 각종 유체를 단속할 수 있는 일반적인 체크 밸브 기능에 유체를 강제적으로 개폐할 수 있는 수단을 부가적으로 설치하여, 유체가 밸브시트(11)에서 고착화되는 현상을 미연에 예방할 수 있고, 그로 인하여 밸브 개폐 작동상의 문제점을일소할 수 있을 뿐만 아니라 소정의 각도 전환에 따라 유체의 이송량 조절은 물론 일반 밸브 기능을 제공하며,As described in detail above, the control check valve 1 provided in the present invention additionally includes means for forcibly opening and closing the fluid in a general check valve function capable of intermitting various fluids, thereby allowing the fluid to be valved. Fixing phenomenon in the seat 11 can be prevented in advance, thereby not only can eliminate the problem of valve opening and closing operation, but also provides a general valve function as well as adjusting the flow rate of the fluid according to a predetermined angle change.

선택적으로 체크 밸브 기능 및 강제 개폐 작동이 가능하여 다양한 유체 이송분야에 호환성 있게 사용될 수 있고,Optional check valve function and forced open / close operation make it compatible with various fluid transfer applications.

체크 밸브가 기능을 상실했을 시에 밸브를 폐쇄작동으로 전환시킨 후 누수없이 매립조치 할 수 있는 등 그 기대되는 효과가 다대한 발명이다.When the check valve loses its function, the present invention has a great effect such that the valve can be closed and then landfilled without leakage.
