Description
본 발명은 볼밸브에 관한 것으로, 특히 밸브의 외부에서 밸브의 작동과 안전조건에 관련하여 밸브자체의 취급을 위한 기구와 같은 장치에서 유량과 같은 정보를 판독할 수 있도록 하는 유량검출기 또는 유량계가 결합되는 볼밸브에 관한 것이다.The present invention relates to a ball valve, in particular a flow detector or flow meter coupled to enable the reading of information such as flow rate in a device such as a mechanism for handling the valve itself in relation to the operation of the valve and safety conditions outside the valve. It relates to a ball valve.
차단밸브, 특히 볼밸브의 내부를 흐르는 유체의 유량을 판독하는 것은 잘 알려져 있다. 밸브의 외부에서 기구에 의하여 이러한 정보를 얻는 방식은 잘 알려져 있으나 이러한 방식은 복잡한 연결구조를 요구함으로서 밸브가 어떤 조건에 있어서는 사용될 수 없도록 하는 경우가 있다. 아울러, 이러한 방식은 각 단일 밸브의 유량을 판독하는 것이 이 밸브를 통하여 유동하는 유체의 형태와 특정용도에 요구되는 상기 유체의 양에 따라서 달라질 수 있어 전용의 측정수단에 의존하여야 하는 불편한 점이 있다.It is well known to read the flow rate of a fluid flowing inside a shutoff valve, in particular a ball valve. The manner in which this information is obtained by means of a mechanism outside the valve is well known, but this method requires a complicated connection structure so that the valve cannot be used under certain conditions. In addition, this method is inconvenient in that reading the flow rate of each single valve may depend on the type of fluid flowing through the valve and the amount of the fluid required for a particular use, and thus must be resorted to dedicated measuring means.
밸브의 내부를 유동하는 유체의 유량을 판독하기 위한 다른 방법이 예를 들어 특허문헌 EP 0671578에서 제안된 바 있다. 그러나, 이러한 방법에 있어서는 판독기구의 형태에 따라서 실제의 유량이 변화되어 판독 자체가 부정확하게 된다.Another method for reading the flow rate of the fluid flowing inside the valve has been proposed, for example, in patent document EP 0671578. In this method, however, the actual flow rate changes depending on the type of the reading mechanism, and the reading itself becomes inaccurate.
본 발명에 있어서는 밸브의 구조가 유량에 영향을 주지 않는 요소를 가지고 정확한 판독이 이루어질 수 있으며 유체의 형태와 유체가 밸브에 가하는 부하로부터 유도되는 모든 조건에 적응될 수 있는 볼밸브를 제공하는데 그 목적이 있다.In the present invention, the valve structure has an element which does not affect the flow rate, accurate readings can be made and the ball valve can be adapted to all conditions derived from the type of the fluid and the load applied to the valve. There is this.
본 발명을 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.Referring to the present invention in more detail based on the accompanying drawings as follows.

도면에서, 두개의 외부플랜지(2)(3)를 갖는 볼밸브(1)는 필요한 경우 복합구조의 환상씨일(5)에 의하여 위치가 고정되는 볼(4)이 분리될 수 있게 되어 있다. 이러한 밸브는 잘 알려진 형태로서 분해와 조립이 간단하고 안정하게 이루어질 수 있도록 하는 연결롯드(6)가 구비되어 있다.In the figure, the ball valve 1 having two outer flanges 2 and 3 is capable of separating the balls 4 which are fixed in position by the annular seal 5 of the composite structure if necessary. Such a valve is of well-known form and is provided with connecting rods 6 which allow easy and stable disassembly and assembly.
본 발명에 따라서, 밸브(1)는 핀(7)에 의하여 작동되는 볼(4)을 가지며, 볼(4)의 내부에 적당히 가공되는 환상벽(11)으로 통공(8)이 형성되며, 이 통공은 밸브의 축선에 평행하게 연장되어 있다. 이 통공(8)의 크기는 밸브를 통하여 유동하는 유체의 유동량을 제한할 수 있도록 맞추어져 있어 유체의 유동방향에 대하여 통공 양측의 압력차이를 사전에 결정할 수 있다.According to the invention, the valve 1 has a ball 4 actuated by a pin 7 and a through hole 8 is formed by an annular wall 11 which is suitably machined inside the ball 4. The through hole extends parallel to the axis of the valve. The size of the through hole 8 is adapted to limit the flow amount of the fluid flowing through the valve, so that the pressure difference between both sides of the through hole relative to the flow direction of the fluid can be determined in advance.
아울러, 볼의 전후에는 두개의 외부플랜지에 인접하여 배치되는 두개의 압력인출구(9)(10)가 형성되어 있다. 이들 압력인출구는 유체의 유동에 대하여 정확히 가공된 통공 양측에서 압력을 측정할 수 있도록 하며 변환에 의한 유량의 측정이 이루어질 수 있도록 한다. 밸브의 연결롯드(6)에 대칭으로 조합된 상기 압력인출구(9)(10)는 유체의 유동파라메타와 유량이 측정되어야 하는 유체의 형태에 따라서 축방향으로 회전될 수 있다. 동일한 방법으로, 플랜지형 커플링이 구성되어 있어 유체의 특성, 열역학적 특성과 유체역학적 특성에 따라서 볼(4)은 정확한 크기의 통공(8)을 갖는 다른 것으로 교환될 수 있다.In addition, before and after the ball, two pressure outlet ports 9 and 10 are disposed adjacent to the two outer flanges. These pressure outlets allow the pressure to be measured on both sides of the precisely engineered through-holes for the flow of the fluid and allow the measurement of the flow rate by conversion. The pressure outlets 9 and 10 coupled symmetrically to the connecting rod 6 of the valve can be rotated axially depending on the flow parameter of the fluid and the type of fluid whose flow rate is to be measured. In the same way, the flanged coupling is constructed so that the ball 4 can be exchanged for another one having the correct sized aperture 8 depending on the fluid, thermodynamic and hydrodynamic properties of the fluid.
본 발명에 따라서, 밸브에는 측정된 유량정보의 변환, 판독 및 전송을 위한 연결수단이 구비되는 것이 좋으며, 측정된 유량정보에 따라서 원격조작하고 요구에 따라서 밸브를 폐쇄 또는 개방할 수 있도록 하는 작동기가 밸브의 핀(7)에 직접 연결될 수 있다.According to the present invention, the valve is preferably provided with a connecting means for converting, reading and transmitting the measured flow rate information, and an actuator for remote operation according to the measured flow rate information and for closing or opening the valve as required. It can be directly connected to the pin 7 of the valve.
이와 같이, 본 발명은 밸브의 외부에서 밸브의 작동과 안전조건에 관련하여 밸브자체의 취급을 위한 기구와 같은 장치에서 유량과 같은 정보를 판독할 수 있도록 하는 유량검출기 또는 유량계가 결합되는 볼밸브를 제공한다.As such, the present invention provides a ball valve coupled to a flow detector or flow meter to enable reading of information such as flow rate from a device such as a mechanism for handling the valve itself in relation to the operation and safety conditions of the valve outside the valve. to provide.
