Description

유량제어밸브{flow control valve}A flow control valve

본 발명은 유량제어밸브에 관한 것으로, 배관 내에 설치되어 유량을 제어하는 밸브이며 내부의 디스크가 회전가능한 구조로 하여 개폐하고, 또한 디스크가 전,후 이동 가능한 구조로 하여 시트에 고착화된 이물질을 제거하면서 밀착력을 높일 수 있는 유량제어밸브에 관한 기술이다.The present invention relates to a flow control valve, which is provided in a piping and controls a flow rate, and has a structure in which an internal disk is rotatable to open and close, and a structure in which a disk can be moved forward and backward, And a flow control valve capable of increasing the adhesion.

유량제어밸브는 디스크가 작동되어 유로를 개폐하게 하는 구조이다. 본 발명과 관련된 유량제어밸브는 디스크의 회전동작에 의해 유로를 개폐하는 방식인 버터플라이밸브형에 관한 것이다.The flow control valve is a structure for opening and closing the flow path by operating the disk. A flow control valve related to the present invention relates to a butterfly valve type which is a method of opening and closing a flow path by a rotation operation of a disk.

일반적인 유량제어밸브의 종류를 보면 밸브몸체 내부에 디스크가 밀착되는 시트가 형성되고, 밸브몸체 내부에 축과 연결된 디스크가 회전되어 시트와 밀착되게 되면 폐쇄된다.A general type of flow control valve includes a valve body in which a disk is closely attached, and a disk connected to the shaft is rotated inside the valve body to close the valve when the valve is in close contact with the valve body.

종래에는 디스크가 회전에 의해 유로를 개방하거나 폐쇄하게 되는데 디스크와 시트 사이의 이물질이 있는 경우 밀폐가 용이하지 않은 문제점이 있어왔다. 즉, 시트나 디스크의 접촉면에 이물질이 고착화되게 되면 폐쇄시 시트와 디스크 사이에 들뜨는 형상이 생기기 때문이다.Conventionally, when the disc is opened or closed by rotation, there is a problem that it is not easy to seal the disc when there is foreign matter between the disc and the disc. That is, when the foreign matter is fixed to the contact surface of the sheet or the disk, a floating shape occurs between the sheet and the disk at the time of closing.

이러한 문제점이 발생하게 되면 밸브를 수리하거나 교체해야 시간과 비용이 많이 발생하므로 이물질이 시트상에 고착화를 방지할 수 있는 기술이 요구된다.If such a problem occurs, repair or replacement of the valve requires much time and expense, and a technique for preventing foreign matter from sticking to the seat is required.

이하, 첨부된 도면을 참고로 본 발명의 바람직한 실시예에 대하여 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.

도 1은 본 발명의 실시예에 따른 유량제어밸브의 내부구성도이다.1 is an internal configuration diagram of a flow control valve according to an embodiment of the present invention.

도 1을 참조하면, 본 발명은 밸브몸체(100), 디스크(200), 직선액추에이터(300), 회전액추에이터(400)를 포함하여 이루어지고, 회전되는 디스크를 전,후진 가능하는 것을 특징으로 한다.1, the present invention includes a valve body 100, a disk 200, a linear actuator 300, and a rotary actuator 400, and is characterized in that the disk to be rotated can be moved forward and backward .

도 2는 본 발명의 실시예에 따른 유량제어밸브의 내부구성도이다.2 is an internal configuration diagram of a flow control valve according to an embodiment of the present invention.

도 2를 참조하면, 상기 밸브몸체(100)는 배관 사이에 설치되고 내주면에 상기 디스크(200)를 받치는 시트(120)가 형성되게 된다.Referring to FIG. 2, the valve body 100 is installed between pipes, and a seat 120 supporting the disk 200 is formed on an inner circumferential surface thereof.

상기 디스크(200)는 상기 밸브몸체(100) 내부에 설치되어 회전에 의해 유로를 개폐할 수 있게 된다.The disc 200 is installed inside the valve body 100 and is capable of opening and closing the passage by rotation.

여기서, 상기 디스크(200)는 원판형으로 형성되고, 상,하부에 블록이 형성되어 상기 직선액추에이터(300)와 회전액추에이터(400)에서 발생하는 동력을 전달 및 차단하는 구조로 연결되어 디스크(200)를 전,후 이동되게 하고 또한 회전이 가능한 구조를 제공하게 된다.Here, the disk 200 is formed in a disk shape, and blocks are formed on the upper and lower sides to be connected with the structure for transmitting and blocking the power generated in the linear actuator 300 and the rotary actuator 400, To be moved forward and backward and to provide a structure that can be rotated.

구체적으로 상기 디스크(200)의 블록의 표면과 길이가 긴 형태의 직선가이드홈이 형성되고, 블록의 외주면에 곡선형의 단턱이 형성되게 된다.Specifically, a straight guide groove having a shape of a long length from the surface of the block of the disc 200 is formed, and a curved step is formed on the outer peripheral surface of the block.

여기서, 직선가이드홈이 형성됨으로써 상기 회전액추에이터(400)의 동작에 디스크(200)가 회전이 되도록 연동시킬 수 있고, 단턱이 형성됨으로써 상기 직선액추에이터(300)의 동작에 디스크(200)가 전,후 이동이 되도록 연동시키게된다. 이러한 동작이 상호 간섭되지 않는 것은 직선액추에이터(300)와 회전액추에이터(400)의 결합구조에서 알 수 있는데 이후 상세 설명하기로 한다.Here, the linear guide groove may be formed so that the disc 200 can be interlocked with the operation of the rotary actuator 400 and the disc 200 can be interlocked with the operation of the linear actuator 300 by forming the step, So as to be moved backward. It is known from the coupling structure of the linear actuator 300 and the rotary actuator 400 that these operations are not interfered with each other and will be described in detail later.

상기 직선액추에이터(300)는 상기 디스크(200)에 결합되어 전진에 의해 상기 디스크(200)를 상기 시트(120)에 밀착시켜 폐구시키게 하고, 후진에 의해 상기 디스크(200)를 상기 시트에 이격시켜 회전할 수 있도록 한 것이다.The linear actuator 300 is coupled to the disc 200 to advance the disc 200 in close contact with the sheet 120 to close the disc 200. The disc 200 is separated from the disc 200 by backward movement So that it can rotate.

여기서, 상기 직선액추에이터(300)는 핸들과, 핸들 방향에 따라 회전되는 기어박스와, 기어박스에 연결되어 전,후진 되는 가이드봉으로 구성할 수 있다.Here, the linear actuator 300 may include a handle, a gear box rotated in the handle direction, and guide rods connected to the gear box to move forward and backward.

이렇게 상기 디스크(200)를 전,후 이동시키는 이유는 전진에 의해 시트(120)에 밀착시킴으로써 밀착력을 높이고 시트(120)에 끼이는 찌꺼기를 밀어서 제거할 수 있기 때문이다.The reason why the disk 200 is moved forward and backward is that the disk 120 is brought into close contact with the sheet 120 by advancing, thereby enhancing the adhesion and removing the debris stuck in the sheet 120.

상기 회전액추에이터(400)는 상기 디스크(200)에 결합되어 상기 시트(120)에서 이격된 디스크(200)를 회전시킬 수 있게 한다.The rotary actuator 400 is coupled to the disc 200 to rotate the disc 200 spaced apart from the seat 120.

상기 회전액추에이터(400)는 단부에 상기 직선가이드홈내에 위치하여 상기 디스크의 직선운동시 가이드되고 회전시에는 간섭되어 상기 디스크에 회전력을 전달하는 사각형상의 스템(420)이 형성되는 것을 특징으로 한다. 여기서 회전액추에이터(400)의 동력은 모터(440)가 되게 된다.The rotary actuator 400 includes a rectangular shaped stem 420 which is positioned at the end of the linear guide groove and is guided when the disk is linearly moved, and is interfered with when rotated to transmit rotational force to the disk. Here, the power of the rotary actuator 400 becomes the motor 440.

즉, 상기 디스크(200)는 직선액추에이터(300)의 작동에 의해 직선이동시 직선가이드홈에 의해 스템(420)에 간섭되지 않아 전,후진 가능하게 되는 것이다. 그리고, 스템(420)이 회전시에만 간섭되어 디스크(200)를 회전시킬 수 있게 되는 것이다. In other words, the disk 200 is not interfered with the stem 420 by the linear guide groove when the linear actuator 300 is moved by the operation of the linear actuator 300, so that the disk 200 can be moved forward and backward. In addition, the stem 420 is interfered only when rotating, and the disc 200 can be rotated.

상기 직선액추에이터(300)는 단부에 상기 단턱의 내외측을 감싸는 형태로 돌출 형성되어 상기 디스크의 회전을 가이드하고 전,후진시에는 간섭되어 상기 디스크에 전,후진 이동되게 하는 클램프(320)가 형성된 것을 특징으로 한다.The linear actuator 300 includes a clamp 320 protruding from the end portion of the step to surround the step, guiding the rotation of the disk, and interfering with the disk when moving forward or backward, .

즉, 상기 디스크(200)는 클램프(320)에 의해 상기 디스크(200)를 전,후진 시킬 수 있게 된다. 이러한 클램프(320)는 단턱의 형상에 대응되는 형태로 형성되어 상기 디스크(200)가 회전시 간섭을 받지 않게 되는 것이다.That is, the disc 200 can be moved forward and backward by the clamp 320. The clamp 320 is formed in a shape corresponding to the shape of the step, so that the disc 200 is not interfered with when the disc 200 rotates.

그러므로, 본 발명은 디스크의 전,후진 이동동작과 회전동작이 가능하도록 하여 각각의 동작이 별도로 가능한 구조에 의해 밀폐시 전진에 의해 밀폐율과 찌꺼지 제거 효율을 높일 수 있으며, 또한 개구가 필요할 때에는 디스크를 후진하여 회전시킬 수 있는 이점이 있다. Therefore, according to the present invention, the forward and backward movement and rotation operation of the disk are enabled and the operation of the disk can be separately performed, thereby increasing the sealing rate and the removal efficiency of the soil by advancing in sealing. There is an advantage that it can be rotated and rotated.

도 3은 본 발명의 실시예에 따른 실링부재의 상세도이다.3 is a detailed view of a sealing member according to an embodiment of the present invention.

한편, 도 3을 참조하면, 상기 디스크(200)의 전면에 탈부착되어 상기 시트에 밀착되는 실링부재(220)가 형성되는 것을 특징으로 한다. 여기서 실링부재(220)는 볼트 결합에 의해 디스크(200)에 분리 결합 가능하게 하여 교체가 용이하며, 또한 실링부재(220)의 형상을 다양하게 형성할 수 있다.Referring to FIG. 3, a sealing member 220 detachably attached to the front surface of the disc 200 to closely contact the sheet is formed. In this case, the sealing member 220 can be detachably coupled to the disc 200 by bolt coupling, and the sealing member 220 can be easily changed, and the shape of the sealing member 220 can be variously formed.

그리고, 실링부재(220)는 메탈 소재로 할 수도 있고, 연성이 있는 폴리계열수지를 사용하여 시트에 밀착력을 더욱 더 높일 수 있다.Further, the sealing member 220 may be made of a metal material, or a poly-based resin having flexibility may be used to further increase the adhesion to the sheet.

하기에서는 본 발명인 유량제어밸브의 작동예시를 설명하기로 하고, 작동예시는 도 4와 5에 표현하였다. Hereinafter, an operation example of the flow control valve of the present invention will be described, and an operation example is shown in FIGS.

도 4는 본 발명의 실시예에 따른 직선액추에이터의 작동에 의해 디스크가 후진된 상태도이다.4 is a state in which the disk is moved backward by the operation of the linear actuator according to the embodiment of the present invention.

도 4를 참조하면, 직선액추에이터(300)의 작동에 의해 디스크(200)가 후진하여 시트(120)에 의해 이격되게 됨으로써 상기 디스크(200)는 회전 가능한 상태가 된다.Referring to FIG. 4, the disk 200 is moved backward by the action of the linear actuator 300, and is separated by the sheet 120, so that the disk 200 becomes rotatable.

도 5는 본 발명의 실시예에 따른 회전액추에이터의 작동에 의해 디스크가 오픈된 상태도이다.5 is a state in which the disc is opened by the operation of the rotary actuator according to the embodiment of the present invention.

도 5를 참조하면, 회전액추에이터(400)의 작동에 의해 후진한 디스크(200)를 회전시켜 배관 내부를 완전히 개구하게 된다.Referring to FIG. 5, the disk 200 is rotated by the operation of the rotary actuator 400 to completely open the inside of the pipe.

반대로 배관 내부를 폐구시에는 디스크(200)를 회전액추에이터(400)의 작동에 의해 원위치로 회전시키고 상기 시트(120)로 밀착시켜 시트(120)내 고착화된 이물질을 제거할 수 있게 된다.On the contrary, when the inside of the pipe is closed, the disc 200 is rotated to the original position by the operation of the rotary actuator 400 and is brought into close contact with the sheet 120, thereby removing the foreign matter fixed in the sheet 120.

도 6은 본 발명의 실시예에 따른 유량제어밸브의 작동 상태를 상측에서 도시한 도이다.6 is a top view of the operating state of the flow control valve according to the embodiment of the present invention.

도 6을 참조하면, 디스크(200)는 상,하부에 블록(240)이 형성되고 블록(240)의 표면과 길이가 긴 형태의 직선가이드홈(242)이 형성되어 있다. 그리고 블록(240)의 외주면에 곡선형의 단턱(244)이 형성되게 된다. 여기 직선가이드홈(242)에는 스템(242)이 위치하게 되고, 단턱(244)은 클램프(320)와 결합되게 된다.Referring to FIG. 6, a block 240 is formed on the upper and lower sides of the disk 200, and a linear guide groove 242 having a longer length than the surface of the block 240 is formed. A curved step 244 is formed on the outer surface of the block 240. In this straight guide groove 242, the stem 242 is positioned, and the step 244 is engaged with the clamp 320.

도 6(a)에서는 디스크가 폐구된 상태이다. 도 6(b)과 같이 직선액추에이터의 작동에 의해 클램프(320)가 디스크(200)를 견인하여 시트(120)에 대해 이격됨으로써 디스크(200)의 회전반경 상에서 시트(120)와 간섭되지 않게 된다. 도 6(c)에서는 회전액추에이터의 스템(420)이 회전함으로써 직선가이드홈(242)과 간섭되어 디스크(200)은 회전시키게 되고 유로를 개방할 수 있게 된다. 이때, 클램프(320)는 블록(240)과 간섭되지 않아 디스크(200)의 회전을 허용하게 한다.In Fig. 6 (a), the disc is in a closed state. The clamp 320 pulls the disc 200 by the operation of the linear actuator as shown in Fig. 6 (b) and is spaced from the seat 120, so that the clamp 320 does not interfere with the seat 120 on the turning radius of the disc 200 . 6 (c), the rotation of the stem 420 of the rotary actuator interferes with the linear guide groove 242, thereby rotating the disc 200 and opening the flow path. At this time, the clamp 320 does not interfere with the block 240, allowing the rotation of the disc 200.
