Abstract

A ball valve having a filtering function is provided to filter foreign material within fluid without disturbing the flow of the fluid and prevent noise and vibration in a valve. A ball valve having a filtering function opens and closes a flow path(21) controlling the fluid flux of a fluid inlet and a fluid outlet by operating an operation lever(1) and rotating a ball(20) within a valve body(10). The fluid flowed through the fluid inlet equipped in one side of the valve body is discharged through the flow path of the ball to the fluid outlet equipped in the other side of the valve body. A filtering groove(22) is equipped in ball at right angle to the flow path. The foreign material of the fluid passing through the flow path is filtered by inserting a strainer(30) into the filter groove. A foreign material drain hole(13) is equipped in the valve body. The foreign material drain hole is positioned in the bottom of the ball.

여과기능을 갖는 볼밸브{BALL VALVE HAVING FUNCTION OF FILTERING}Ball valve with filtration function {BALL VALVE HAVING FUNCTION OF FILTERING}

본 발명은 관로상의 가스나 물 등과 같은 유체의 흐름을 단속하기 위한 볼밸브에 관한 것으로, 더욱 상세하게는 볼에 반원통형의 스트레이너를 내장시켜 유체의 이물질을 여과하고, 여과된 이물질을 그 자중을 이용하여 침강 침적시키도록 구성되는 여과기능을 갖는 볼밸브에 관한 것이다.The present invention relates to a ball valve for regulating the flow of a fluid such as gas or water on a pipeline, and more particularly, by embedding a semi-cylindrical strainer in the ball to filter foreign matters from the fluid, It relates to a ball valve having a filtration function configured to sedimentation deposition using.

일반적으로, 볼밸브는 밸브몸체의 유체통로 상에 관통된 구멍을 갖는 구형의 볼이 내장되어 있고, 이 볼은 유체통로에 배치된 볼 지지링에 밀착됨과 동시에 스템에 연결되어 회전 조작되면서 관로상의 유체흐름을 단속하도록 구성되어 있다.In general, the ball valve has a spherical ball having a hole penetrated on the fluid passage of the valve body, the ball is in close contact with the ball support ring disposed in the fluid passage and connected to the stem and rotated while It is configured to interrupt the fluid flow.

이때, 관로 내를 흐르는 유체에는 그 자체의 이물질과 관로 내부에서 생성되는 이물질 등을 여과하기 위한 여과장치가 필요하게 된다.At this time, the fluid flowing in the pipe is required for a filtration device for filtering foreign matters and the like generated in the inside of the pipe.

등록실용신안 제0274163호에 게재된 볼밸브는 밸브몸체 내에서 유체유입구와 유출구 사이에 연통하여 유체를 필터링하는 스트레이너를 형성시키어 유입된 유체가 스트레이너에서 걸러진 후 작동레바에 연동하는 유로개폐볼의 개통구를 거쳐 유출구쪽으로 유출될 수 있도록 구성되어 있다.The ball valve disclosed in Korean Utility Model No. 0274163 forms a strainer to filter the fluid by communicating between the fluid inlet and the outlet of the valve body so that the flow opening and closing ball interlocked with the operating lever after the inflow of the fluid is filtered out of the strainer. It is configured to flow through the mouth to the outlet.

그러나, 상기 볼밸브는 밸브몸체에 스트레이너몸체를 경사지게 구성하고, 스 트레이너몸체내에 원통형의 스트레이너로 비스듬히 내장시켜 유체가 스트레이너의 내부를 통과하는 과정에서 이물질을 여과하기 때문에 유체의 흐름을 방해하게 되고, 이로 인해 밸브몸체와 스트레이너몸체내의 유체압력이 가중되면서 소음 및 진동 그리고 압력부하에 의한 손상이 유발되는 등의 문제가 있다.However, the ball valve is configured to incline the strainer body to the valve body, and to be inclined in the strainer body with a cylindrical strainer to block the flow of the fluid because the fluid is filtered in the process of passing through the interior of the strainer, As a result, the fluid pressure in the valve body and the strainer body is increased, causing noise, vibration, and damage caused by pressure load.

더욱이, 상기의 볼밸브는 스트레이너몸체에 의해 복잡한 구조를 가지면서 그 부피 및 중량이 커지게 되고, 그 제조원가가 현저히 상승하는 등 실용화할 수 없는 중대한 결함을 안고 있다.Moreover, the ball valve has a serious defect that cannot be put into practical use, such as having a complicated structure by the strainer body, its volume and weight being increased, and its manufacturing cost significantly increasing.

본 발명은 상기한 종래의 문제를 개선하기 위하여 발명된 것으로, 볼에 반원통형의 스트레이너를 내장시켜 유체의 이물질을 여과하고, 여과된 이물질을 그 자중을 이용하여 침강 침적시키도록 구성되는 여과기능을 갖는 볼밸브를 제공함에 그 목적이 있다.The present invention has been invented to improve the above-mentioned conventional problems, and has a filtration function that is configured to filter the foreign matter of the fluid by embedding a semi-cylindrical strainer in the ball, and to sediment and deposit the filtered foreign matter using its own weight. It is an object to provide a ball valve having.

상기한 목적을 달성하기 위하여 본 발명은 작동레버를 작동시키면 밸브몸체내의 볼이 회전되면서 유체유입구와 유체유츌구의 유체흐름을 단속하는 유로를 개폐하도록 구성되는 볼밸브에 있어서, 상기 볼에 상기 유로와 직교하는 여과홈이 구비되면서 상기 여과홈에 스트레이너가 삽입되어 유로를 통과하는 유체의 이물질을 여과하고, 상기 밸브몸체에 이물질드레인구가 상기 볼의 하부측에 위치하도록 구비되면서 이물질드레인캡에 의해 개폐되도록 설치되어 상기 여과홈으로부터 침강되는 이물질을 침적 수거하도록 구성되는 것을 특징으로 하는 여과기능을 갖는 볼밸브를 제공하게 된다.In order to achieve the above object, the present invention provides a ball valve configured to open and close a flow path for controlling a fluid flow of a fluid inlet and a fluid inlet by rotating a ball in a valve body when the operating lever is operated. A strainer is inserted into the filtration groove while the filter groove is orthogonal to filter foreign substances in the fluid passing through the flow path, and the foreign matter drain port is provided on the valve body so as to be positioned at the lower side of the ball, and opened and closed by the foreign matter drain cap. It is provided so as to provide a ball valve having a filtration function, characterized in that configured to collect the foreign matter precipitated from the filtration groove.

이상과 같이 구성되는 본 발명은 그 구조가 간단하면서 콤팩트하고, 유체의 흐름을 방해하지 않으면서 유체의 이물질을 여과할 수 있으며, 이로부터 그 제조원가를 현저히 낮출 수 있을 뿐만 아니라 밸브 내의 소음 및 진동 등을 유발하지 않 등의 효과를 제공하게 된다.The present invention configured as described above is simple and compact in structure, and can filter foreign matters of the fluid without disturbing the flow of the fluid, thereby not only significantly reducing the manufacturing cost thereof, but also noise and vibration in the valve. It does not cause such effects.
