Description

반 볼 밸브의 개방유도장치{Induced Opening Device of Half-ball Valve}Induced Opening Device of Half-ball Valve

본 발명은 밸브 내부에 껍질형태의 반 구체형 볼을 적용시켜 배관을 개폐되도록 하는 대형 반 볼 밸브에 관한 것으로, 특히 폐쇄시 유입구 측에 고압력이 발생할 경우에도 개방작동이 원활하도록 구성한 반 볼 밸브의 개방유도장치에 관한 것이다.
The present invention relates to a large half-ball valve to open and close the pipe by applying a shell-shaped semi-sphere ball inside the valve, in particular, a half-ball valve configured to smoothly open when a high pressure occurs on the inlet side during closing. An open guide device.

도1은 종래의 반 볼 밸브를 도시한 것으로 써, 도시된 바와 같이 본체(A)의 유입구(A1) 측에 반 볼(B)의 표면과 접촉되는 시트(C)가 구비되고, 상기 시트(C)에 스프링(C1)을 탄설하여 반 볼(B)의 표면을 밀도록 구성되어 있다.Fig. 1 shows a conventional half ball valve, and as shown, a seat C is provided on the inlet A1 side of the main body A in contact with the surface of the half ball B, and the seat ( It is comprised so that the spring C1 may be coalesced in C) and the surface of the half ball B may be pushed.

여기에서, 반 볼 밸브는 고압력의 유체공급을 취급할 경우 폐쇄시 유입구 측에 압력이 급격히 상승하게 되는데 이때 상승 유압은 반 볼의 표면을 밀면서 강하게 잡고 있는 작용을 하게 되어 개방을 상당히 어렵게 한다.Here, when the half-ball valve handles a high-pressure fluid supply, the pressure rises rapidly on the inlet side when closing, and the upward hydraulic pressure acts to hold the surface of the half-ball to hold it firmly, making the opening considerably difficult.

이로 인해 반 볼을 회전하기 위한 회전장치에 상당한 부하가 발생함은 물론, 마찰로 인한 시트 및 반 볼의 표면 마모가 심하고, 소음을 야기하며, 각종 작동오류를 야기하게 된다.This causes a considerable load on the rotating device for rotating the half ball, as well as the surface wear of the seat and the half ball due to friction, causes noise, and causes various operating errors.

한편 개방시 시트가 후방으로 약간만 밀려주면 개방이 훨씬 수월해지지만 시트를 밀고 있는 스프링은 상승 유압에 의해 탄성력이 현저하게 떨어지면서 제대로 작동하지 않게 된다.On the other hand, if the seat is pushed slightly to the rear during opening, the opening becomes much easier, but the spring pushing the seat is not able to operate properly due to the remarkable drop in elastic force due to the rising hydraulic pressure.

이에 반 본 밸브는 고압력의 취급에는 온 볼 밸브(구체형 볼로 된 밸브)에 비해 부적합하다는 단점을 안고 있다. 그러나 반 볼 밸브는 저압력의 취급에는 고도의 긴밀성, 정밀한 유량공급, 신속한 ON/OFF, 내부에 별도의 정체공간이 없는 구조적인 이점이 있다. 따라서 가스나 슬러지 취급에는 온 볼 밸브보다 반 볼 밸브가 상당히 유리하다. 하지만 이송속도의 증가, 즉 고압력의 발생에 주의해야 하는 부담이 있다. 그렇다면 반 볼 밸브를 고압력의 취급에도 대응할 수 있도록 개량한다면 그 활용범위는 온 볼 밸브보다 더욱 확대될 것이다. 그러나 현재까지는 이러한 시도가 없었다. 하여 본 발명에서는 이러한 문제점을 해결하고자 한다.
On the contrary, this valve has a disadvantage in that it is inadequate for the handling of high pressure in comparison with an on-ball valve (valve of a spherical ball). However, the half ball valve has the advantages of high pressure, high flow rate, precise flow, fast on / off, and no congestion space inside. Therefore, half ball valves are considerably advantageous over on ball valves for gas or sludge handling. However, there is a burden to pay attention to the increase in the feed speed, that is, the generation of high pressure. Then, if the half ball valve is improved to cope with the handling of high pressure, the application range will be further extended than the on ball valve. But so far no attempt has been made. In order to solve this problem in the present invention.

In order to achieve the above object, the present invention, in the configuration of the conventional half-ball valve, is provided so that the front and rear sliding grooves in the mounting groove inside the inner seat of the main body, the inner peripheral surface of the tip is in contact with the inner outer peripheral surface of the seat, the spring at the rear end It is characterized in that the auxiliary elastic ring that can be pushed to push the seat back to the inlet side.

상기와 같이 된, 본 발명은 개방시 보조탄성링이 시트의 후방 밀림작동을 유도하여 반 볼의 개방작동이 원활해지는 효과가 있다. 또한 상기의 작용은 개방상태에서 폐쇄과정에도 마찬가지로 작용한다. 따라서 본 발명은 반 볼 밸브에 대한 고압력의 대응력을 향상시켜 반 볼 밸브의 적용성을 더욱 확장시킬 수 있는 이점이 있다.
As described above, the present invention has the effect that the auxiliary elastic ring during opening induces the rear push operation of the seat to facilitate the opening operation of the half ball. The above action also works in the closing process in the open state. Therefore, the present invention has an advantage that the applicability of the half ball valve can be further extended by improving the response force of the high pressure with respect to the half ball valve.
