본 고안은 외부에서 유량조절과 개폐변의 닫히는 속도 조절은 물론 밸브내부를 청소할 수 있게 한 개량 체크밸브에 관한 것이다.The present invention relates to an improved check valve that enables to clean the inside of the valve, as well as to control the flow rate and closing speed of the opening and closing valve from the outside.
종래의 체크밸브는 관내 유체흐름의 역류를 방지하는 단순 기능을 갖는 것으로 개폐변의 닫히는 속도가 너무 빨라 위터함마가 발생하며 배관에 충격을 주어 씨스템의 수명을 단축하고 유체내의 이물질이 밸브씨트 상에서 급속도로 타격하므로 밸브 씨트의 가공면을 해치고 이로 인하여 완벽한 역류방지 기능을 발휘할수가 없는 불편한 점이 많이 있었다.Conventional check valves have a simple function to prevent backflow of the fluid flow in the pipe, and the closing speed of the opening / closing valve is too fast. There was a lot of inconvenience that could damage the valve seat machining surface, thereby not be able to achieve the perfect backflow prevention function.
본 고안은 종래의 이와 같은 결점을 해결하고 체크밸브의 개폐로를 외부에서 조절하여 유량제어 밸브의 기능을 갖게 하기 위해 고안된 것으로 밸브의 개폐속도조절과유량조절, 배구, 청소가 가능하도록 한것으로 이를 첨부도면에 의거 상세히 설명하면 다음과 같다.The present invention is designed to solve the above-mentioned shortcomings and to control the opening and closing of the check valve from the outside to have a function of the flow control valve. When described in detail based on the drawings as follows.
밸브본체(1)에 유입구(2)를 향한 경사각(약 45도)상의 실린더(5)저면에 하부캡(10)을 체결하고 피스톤(6)을 볼트(7)로서 결합한 개폐변(8)이 형성된 밸브로드(9)를 삽입하고 밸브로드 가이드(3)가 삽입된 상부 캡(4)을 밸브로드(9)상측에 결착하였으며, 유입구(2)와 실린다(5)의 밑부분을 관통시킨 밸브 작동용 유로(11)의 중간부에 콕크(12)를 설치하고 출구(13)측 본체의 이물질 정체용 쳄바에 드래인 밑 청소용 배관을 할수 있는 구멍(14)을 뚫고 캡(15)을 설치한다.An opening / closing side 8 in which the lower cap 10 is fastened to the valve body 1 on the bottom of the cylinder 5 on the inclination angle (about 45 degrees) toward the inlet 2 and the piston 6 is coupled as a bolt 7 is provided. The formed valve rod 9 was inserted and the upper cap 4 into which the valve rod guide 3 was inserted was attached to the upper portion of the valve rod 9, and the valve penetrating the lower part of the inlet 2 and the seal 5 was inserted. Install the cock 12 in the middle of the operating flow path 11, and drill the hole 14 for drainage cleaning pipe in the catch bar for debris retention on the main body of the outlet 13, and install the cap 15. .
또 상부캡(4)에는 핸들(16)에 결합된 개도조절로드(17)가 팩킹(18)을 끼운팩킹 조임용 캡(19)을 개도조절로드(17)와 핸들(16)이 회전 가능토록 고정시킨 구조이다.In addition, the upper cap (4), the opening adjustment rod (17) coupled to the handle 16, the packing cap 18 for tightening the packing 18, the opening adjustment rod (17) and the handle (16) is rotatable. It is a fixed structure.
이와 같이 된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention made as follows.
차단되어 있던 유체를 순환시키기 위해 개폐변(8)을 개방코저 할때는 먼저 잠겨져 있는 밸브작동용 유로(11)의 중간부 콕크(12)를 열어 유입구(2)와 실린다(5)사이를 연결시켜 주는 밸브 작동용 유로(11)를 개방하면 유입구(2)로 유입되는 유체와 같은 동일 압력으로 밸브 작동용 유로(11)를 따라 실린다(5)내의 피스톤(6)과 하부캡(10)의 사이에 유입되어 유체가 모이면서 서서히 피스톤(6)이 위로 움직이면 여기에 일체로 결합된 밸브로드(9)와 개폐변(8)이 상측으로 밀리어 개폐변(8)이 열리게 되고 유체는 유출구(13)쪽으로 흐르게 되는 것이다.When opening and closing the opening / closing valve 8 to circulate the blocked fluid, first open the middle cock 12 of the valve operating flow passage 11 that is locked to connect the inlet port 2 and the seal 5. When the valve operating flow passage 11 is opened, it is loaded along the valve operating flow passage 11 at the same pressure as the fluid flowing into the inlet port 2 between the piston 6 and the lower cap 10 in the 5. When the piston 6 moves upward while the fluid is collected, the valve rod 9 and the opening / closing valve 8 which are integrally coupled thereto are opened upward, and the opening / closing valve 8 is opened, and the fluid is the outlet 13. It will flow toward.
이와 같은 본 고안에 있어 상부캡(4)과 여기에 결합된 밸브 로드 가이드(3)로는 밸브로드(9)의 중심을 잡아주면, 누수를 방지하여 준다.In the present invention as described above, by holding the center of the valve rod 9 to the valve rod guide 3 coupled to the upper cap 4, it prevents leakage.
또 팩킹(18)과 팩킹 조임용 캡(19)에 결합된 핸들(16)의 회전으로 개도조절로드(17)을 상하로 움직여 주면 밸브로드(9)의 이동폭을 조절하여 유입구(2)를 통과하는 유량을 많게 또는 적게 자유로이 유량조절이 가능한 것이다.In addition, when the opening control rod 17 is moved up and down by the rotation of the handle 16 coupled to the packing 18 and the packing cap 19, the inlet opening 2 is adjusted by adjusting the moving width of the valve rod 9. It is possible to adjust the flow rate freely with high or low flow rate.
그리고 유체의 공급이 중단되면 제2도와 같이 콕크(12)가 열린 상태에서는 피스톤(6)저면 실린다(5)내에 모인 유체가 밸브 작동용 유로(11)와 콕크(12)를 지나 유입구(2)로 역순환되면서 밸브로드(9)는 서서히 아래로 내려가 개폐변(8)이 원상태로 환원되면서 유체의 역류를 막아주며 안전하게 차단되는 것이다.When the supply of the fluid is stopped, in the state in which the cock 12 is opened as shown in FIG. 2, the fluid collected in the bottom of the piston 6 passes through the valve operating flow path 11 and the cock 12 and the inlet 2. The valve rod (9) is slowly lowered while being reversely circulated to prevent the reverse flow of the fluid while the open / close valve (8) is returned to its original state and is safely shut off.
이렇게 사용하다 밸브 본체(1)의 청소나 동절기에 동파 방지를 위해 콕크(12)로 밸브작동유로(11)를 차단하여 피스톤(6)과 실린다(5) 사이에 유체가 정체된 상태가 되면 피스톤(6)은 개폐변(8)이 열린 상태에서 움직이지 않으므로 개폐변(8)이 개방되어 있어 유출구(13)에 연결된 파이프(도시하지 않았음)에 모여 있던 유체는 유입구(2)쪽으로 일시에 역류하여, 유출구(13)쪽에는 텅비어 있는 상태가 되고 역류하는 과정에서 파이프내의 이물질등이 제거가 되며, 또 동절기의 동파도 자연 방지되는 것이다.In this way, the valve operating flow path 11 is blocked by the cock 12 to clean the valve body 1 or to prevent freezing during winter, and when the fluid is stagnated between the piston 6 and the seal 5, the piston (6) does not move in the open state (8) is open, so the open and close side (8) is open so that the fluid gathered in the pipe (not shown) connected to the outlet (13) at a time toward the inlet (2) It flows backward, becomes empty at the outlet 13 side, foreign substances in a pipe are removed in the process of backflow, and the freezing of winter is also prevented naturally.
이와 같이 된 본 고안은 개폐변이 사향으로 되어 있어 이물질이 잔류할수 없으며, 밸브 내부를 간단하게 청소하고저 할 경우 본체 유출구 측의 구멍(14)에 결합된 캡(15)만을 풀어주면 유출구(13)측 본체(1)에 모인 잔류 유체를 전부 제거할수 있는 것으로 두개의 구멍(14)으로 된 것은 밸브의 설치 각도에 따라 수직 또는 수평으로 설치하던 공히 손쉽게 청소할 수 있게 하기 위해 형성한 것이다.The present invention has the opening and closing sides are musk, foreign matter can not remain, and if you simply clean the inside of the valve to loosen the cap 15 coupled to the hole 14 on the outlet side of the main body outlet 13 Residual fluid collected in the side main body 1 can be removed. The two holes 14 are formed so that they can be easily cleaned vertically or horizontally depending on the installation angle of the valve.
또 콕크의 개방폭에 따라 외부에서 개폐변의 닫히는 속도를 쉽게 조절할수 있어 밸브에 무리가 없이 사용할수 있는 유용한 고안인 것이다.In addition, according to the opening width of the cock can be easily controlled the closing speed of the opening and closing valve from the outside, it is a useful design that can be used without any burden on the valve.
