Description
본 고안은 배관내의 물이나 유류, 가스등과 같은 각종유체의 유량을 제어하는 유량조절밸브에 관한 것으로, 더욱 구체적으로는 2개이상으로 분할되어 있는 분할디스크가 구성되어 그 분할디스크에 의해 관로개폐가 이루어지도록 한 구성으로 유량개폐작동이 신속하고 정확한 유량조절을 할 수 있는 유량조절밸브에 관한 것이다.The present invention relates to a flow control valve for controlling the flow rate of various fluids, such as water, oil, gas, etc. in the pipe, more specifically, divided into two or more divided disks are configured to open and close the pipeline The present invention relates to a flow control valve capable of quickly and precisely controlling flow rate by opening and closing the flow in one configuration.
일반적으로 유량조절밸브는 물이나 유류, 가스등과 같은 각종 유체가 흐르는 배관내에 설치되어 유체의 흐름을 차단하거나 흐르는 유량을 조절하는데 사용되고 있다.In general, the flow control valve is installed in a pipe through which various fluids, such as water, oil, and gas flow, is used to block the flow of the fluid or to control the flow rate.
이러한 유량조절밸브는 크게 글로브밸브, 게이트밸브, 버터플라이밸브, 볼밸브등으로 구분되어 사용되고 있으며 그 구조 및 특성은 다음과 같다.These flow control valves are largely divided into globe valves, gate valves, butterfly valves, ball valves, etc., and their structure and characteristics are as follows.
글로브밸브는; 밸브의 개폐작동을 빠르게 할 수 있는 장점이 있는데 반하여, 관로내에서 유체의 흐르는 방향이 S자형으로 바뀌는 구조로 되어 있고 밸브가 유체중에 있기 때문에 유체의 에너지 손실 계수가 높은 단점을 가지고 있다.Globe valves; While there is an advantage that the opening and closing operation of the valve can be faster, the flow direction of the fluid in the conduit is changed to an S-shape, and the energy loss coefficient of the fluid is high because the valve is in the fluid.
게이트밸브(슬루브밸브)는; 관로의 흐름에 밸브가 직각으로 놓여져서 밸브의 승강운동에 의해 관로개폐가 이루어지는 구성으로, 밸브개방시에 관로의 일직선상으로 유체흐름이 이루어져서 유체에 미치는 영향이 적기 때문에 유체의 손실계수는 낮은 장점 있는데 반하여, 밸브개폐를 위하여 밸브를 나사방식으로 돌려 승강시키는데 따른 밸브 개폐작동시간이 많이 걸리는 단점이 있다.The gate valve (slew valve) is; The valve is placed at right angles to the flow of the pipeline, and the opening and closing of the pipeline is caused by the lifting and lowering movement of the valve.The fluid loss coefficient is low because the fluid flows in a straight line of the pipeline when the valve is opened. On the other hand, there is a disadvantage in that the valve opening and closing operation time takes a long time due to the lifting and lowering of the valve for the valve opening and closing.
버터플라이밸브는; 관로내에서 원판상의 밸브를 돌려 관로의 유량을 조절하는 밸브로서, 개폐조작방법이 간편한 장점이 있는데 반하여 밸브가 유체의 흐름에 직각방향으로 회전함으로 밸브개폐작동에 많은 힘이 들고 밸브의 완전개폐시에도 밸브가 유체중에 있어 유체의 손실계수가 높다.Butterfly valves; It is a valve that controls the flow rate of the pipeline by turning the valve on the disk in the pipeline, and has the advantage of simple opening and closing operation, while the valve rotates in a direction perpendicular to the flow of the fluid, which increases the force in the valve opening and closing operation and completely opens and closes the valve. Even though the valve is in the fluid, the loss factor of the fluid is high.
볼 밸브는; 개폐조작방법이 간편한 장점이 있는데 반하여 밸브가 유체의 흐름에 직각방향으로 회전을 하므로 밸브개폐작동에 많은 힘이 들고 설치구조가 커지는 단점이 있다.Ball valve; While the opening and closing operation is simple, the valve rotates in a direction perpendicular to the flow of the fluid, and thus, there is a disadvantage in that a lot of force is applied to the valve opening and closing operation and the installation structure becomes large.
또한, 상기와 같은 일반적인 유량조절밸브에서는 단일밸브에 의해 관로개폐가 이루어지므로 유량조절을 위하여 밸브를 중간정도 개방하는 경우에 관로의 일측부분만을 완전 차단하는 형태로 되어 있는바, 이는 관로의 배출부분에 위치한 밸브의 차단공간이 한쪽에 치우친 형태이므로 그 밸브 차단부분 반대편에서 와류발생이많아져서 관로의 유체흐름에 지장을 초래하게되는 유량손실계수에 의해 정확한 유량조절에 어려움이 많았다.In addition, in the general flow control valve as described above, since the pipeline is opened and closed by a single valve, only one side of the pipeline is completely blocked when the valve is opened halfway for flow control. Since the blocking space of the valve located in the side is biased on one side, it was difficult to control the precise flow rate by the flow loss coefficient which caused vortices on the opposite side of the valve blocking part, which caused the flow of the pipeline.
본 고안은 이러한 문제점을 해결하기 위하여 관로의 유체흐름방향에서 직각으로 2개이상의 분할디스크에 의해 개폐작동되게한 유량조절밸브의 구성으로 유량개폐간격을 최소화하여 유량개폐작동이 신속하고 유량손실계수를 최소화하여 정확한 유량조절이 가능하도록 한 것이다.In order to solve this problem, the present invention has a flow control valve configured to be opened and closed by two or more divided disks at right angles in the direction of fluid flow in the pipeline to minimize the flow opening and closing intervals, so that the flow opening and closing operation is quick and the flow loss coefficient is increased. Minimizing the flow rate is possible.

The partition disk 4 is configured to be in close contact with each other, but the contact end surface 43 is preferably used by attaching or integrally attaching a packing member to increase the adhesion.
상기 회동안내홈(42)은 장방향으로 형성하되 회동안내홈(42)에 끼워진 조절판(5)의 작동핀(52)이 3개의 분할디스크(4)가 관로(10)내에서 서로 내향접촉되거나 관로(10) 외주의 작동공간부(11)로 놓여지도록 한다.The inner groove 42 is formed in the longitudinal direction, but the operation pin 52 of the control plate 5 fitted in the inner groove 42 is rotated inwardly in contact with each other in the three dividing disks 4 in the conduit 10.

이와같이 된 본 고안은 밸브본체(1)의 유입관(2)과 배출관(3) 사이에 2개이상의 분할디스크(4)가 관로(10)의 유체흐름방향과 직각으로 작동하여 관로(10) 개폐를 하는 유량조절을 하게 된다.In this way, the present invention has two or more split disks (4) between the inlet pipe (2) and the discharge pipe (3) of the valve body (1) operates at right angles to the fluid flow direction of the pipe (10) opening and closing the pipe (10) It is to control the flow rate.
도 1은 밸브본체(1)내의 분할디스크(4)가 관로(10) 외주의 작동공간부(11)에 각각 놓여져서 관로(10)의 개방이 이루어진 것을 나타낸 것이다.Figure 1 shows that the divided disk 4 in the valve body 1 is placed in the working space 11 of the outer periphery of the conduit 10 so that the conduit 10 is opened.
도 2는 밸브본체(1) 내의 조절판(5)이 회동작동관(6)에 의해 관로(10) 주위를 원호상 회동하여 분할디스크(4)의 회동안내홈(42)에 끼워진 조절판(5)의 작동핀(52)으로 분할디스크(4)를 지지축핀(41)을 축으로 회동시켜 관로(10) 외주의 작동공간부(11)에서 관로(10)의 중심축선상으로 분할디스크(4)를 중간정도 내향시킨 상태로 관로(1)를 중간정도 차단한 유량조절상태를 나타내고 있다.FIG. 2 shows a throttle plate 5 in which the throttle plate 5 in the valve body 1 is circularly rotated around the duct 10 by a rotatory operating tube 6 and fitted into the inner groove 42 of the divided disk 4. The split disk 4 is rotated around the support shaft pin 41 by the actuating pin 52 of the split disk 4 on the central axis of the conduit 10 in the working space 11 of the outer periphery of the conduit 10. The flow rate regulation state which cut | disconnected the pipe | tube 1 halfway in the state which turned inward halfway is shown.
도 3은 밸브본체(1)내의 분할디스크(4)가 조절판(5)의 회동작동에 의해 분할디스크(4)의 접촉단면(43)이 관로(10)의 중심축성상에서 밀착되게 서로 접촉되어 관로(10)를 차단한 상태를 나타내고 있다.3 shows that the divided disks 4 in the valve body 1 are in contact with each other such that the contact end surfaces 43 of the divided disks 4 are in close contact with each other on the central axis of the conduit 10 by the rotation operation of the adjusting plate 5. The state which blocked (10) is shown.
이렇게 밸브본체(1)내의 관로(10) 개폐작동이 이루어지는 분할디스크(4)는 도5내지 도8에서와 같이 관로(10)의 외주에 배치되어 유입관(2)에 고정된 지지축핀(41)을 축으로 회동하여 관로(10) 개폐를 하되 조절판의 작동핀(52)이 분할디스크(4)의 회동안내홈(42)을 따라 원호상으로 회동함으로서 분할디스크(4)가 관로(10) 외주에 놓여져서 관로(10) 개방상태를 유지하거나 관로(10)의 중심축선상으로 내향되어 관로(10)내의 유량을 조절하게 된다.The partition disk 4 in which the opening and closing operation of the conduit 10 in the valve body 1 is performed is disposed on the outer circumference of the conduit 10 as shown in FIGS. The shaft 10 is opened and closed, but the operation pin 52 of the throttle plate rotates in an arc shape along the inner groove 42 of the partition disk 4 so that the partition disk 4 is connected to the pipeline 10. It is placed on the outer circumference to maintain the open state of the conduit 10 or inward on the central axis of the conduit 10 to adjust the flow rate in the conduit 10.
즉, 이는 도9에서 조절판(5)에 의해 분할디스크(4)가 내향되어 관로(10)를 중간정도 차단한 상태를 나타낸 바와 같이 조절판(5)의 회동에 의해 분할디스크(4)의 개폐작동이 이루어지게된다.That is, this is the opening and closing operation of the partition disk 4 by the rotation of the adjustment plate 5 as shown in the state in which the partition disk 4 is inwardly blocked by the control plate 5 in FIG. This is done.
상기와 같이 관로(1)의 개폐시에 2개이상의 분할디스크(4)가 관로(10)의 중심축선을 정점으로 개폐가 이루어지므로 그만큼 분할디스크(4)의 개폐간격이 종래보다 크게 줄어들게되어 유량개폐작동이 신속하게 이루어지고 관로(10)를 중간정도 차단하는 유량조절상태에서는 각각의 분할디스크(4)에 의해 관로(10) 내부의 차단부위가 분산되므로 차단부분 반대편의 와류발생을 최소화하게되어 원활한 유체흐름으로 유량조절의 정확성을 기할 수 있게된다.As described above, since two or more split disks 4 open and close at the apex of the central axis of the pipe 10 at the time of opening and closing of the pipe line 1, the opening and closing intervals of the split disk 4 are significantly reduced than before. Opening and closing operation is made quickly and in the flow rate control state to block the pipeline 10 in the middle, since the blocking portion in the pipeline 10 is dispersed by each divided disk 4 to minimize the occurrence of vortex on the opposite side of the blocking portion Smooth fluid flow ensures accurate flow control.
또한, 본 고안의 밸브본체(1)는 종래의 배관 플랜지를 이용하여 구성할 수 있고 그 구조가 간단할 뿐만 아니라 배관연결기능을 함께 이루어진다.In addition, the valve body (1) of the present invention can be configured using a conventional pipe flange, the structure is not only simple, but also performs a pipe connection function.
이상에서 본 고안은 상기 실시예를 참고하여 설명하였지만 본 고안의 기술사상범위내에서 다양한 변형실시가 가능함은 물론이다.Although the present invention has been described with reference to the above embodiment, various modifications are possible within the technical scope of the present invention.
이와같이 본 고안의 유량조절밸브는 2개이상의 분할디스크에 의해 관로개폐가 이루어지므로 관로를 개폐하는 분할디스크의 개폐간격이 종래보다 크게 줄어들게 되어 관로의 개폐작동이 신속하게 이루어지고, 유량조절시에도 분할디스크에 의해 관로내부가 분산된 차단부위를 갖게 되어 관로의 와류발생을 최소화하게 되므로 유체흐름을 원활히하여 정확한 유량조절상태를 유지할수 있게 된다.In this way, the flow control valve of the present invention is the opening and closing of the pipeline by two or more divided disks, so the opening and closing intervals of the divided disks to open and close the pipeline is greatly reduced than before, the opening and closing operation of the pipeline is made quickly, even when the flow control is divided Since the inner part of the pipeline is dispersed by the disk, the vortex generation is minimized because the vortex of the pipeline is minimized, so that the fluid flow can be smoothly maintained to maintain accurate flow rate control.
또한, 종래의 배관플랜지를 이용하여 밸브본체를 구성할수 있고 그 구조도 간단하므로 매우 경제적인 이점이 있다.In addition, the valve body can be configured using a conventional pipe flange, and the structure thereof is also simple, so there is a very economic advantage.
