개폐표시용 레버가 구비된 웨이퍼형 스윙체크밸브{Wafer-type swing check valve with the lever which indicates whether it is open or shut}Wafer-type swing check valve with the lever which indicates whether it is open or shut}

본 발명은 개폐표시용 레버가 구비된 웨이퍼형 스윙체크밸브에 관한 것으로, 보다 상세하게는 원판형상으로 된 밸브몸체의 외부에 밸브몸체의 내부에 힌지식으로 설치된 밸브개폐용 디스크와 연동하게 되는 개폐표시용 레버가 설치되도록 구성되므로써 밸브의 작동여부 및 개폐상태를 외부에서 확인할 수 있게 되어 더욱 더 용이하게 유지관리할 수 있게 되며, 또 상기 개폐표시용 레버의 상단에 밸브몸체의 내부에 힌지식으로 설치된 밸브개폐용 디스크의 회동을 방지하는 잠금핀이 삽입설치되도록 구성되므로써 밸브의 운반이나 설치작업을 위한 취급시 밸브개폐용 디스크의 회동이 방지되어 더욱 더 용이하게 취급할 수 있게 되고, 또 상기 개폐표시용 레버의 외측에 밸브개폐용 디스크의 개폐압력을 조절하기 위한 링형상의 중량추가 상하로 이동가능하게 삽입설치되도록 구성되므로써 밸브개폐용 디스크의 개폐압력을 더욱 더 용이하게 조절할 수 있게 되는 개폐표시용 레버가 구비된 웨이퍼형 스윙체크밸브에 관한 것이다.The present invention relates to a wafer-type swing check valve provided with an opening / closing display lever. More specifically, the opening / closing mechanism is interlocked with a valve opening / closing disc which is hinged to the inside of the valve body. Since the display lever is configured to be installed, the operation of the valve and the open / close state can be checked from the outside, so that it can be more easily maintained, and hinged on the inside of the valve body at the top of the open / close display lever. The locking pin for preventing rotation of the installed valve opening and closing disk is inserted and installed so that the valve opening and closing disk can be prevented from being rotated during handling or transportation of the valve so that the valve can be handled more easily. On the outside of the display lever, a ring-shaped weight is moved up and down to adjust the opening and closing pressure of the valve opening and closing disc. The present invention relates to a wafer-type swing check valve with an opening / closing display lever which is configured to be inserted and installed to enable the opening / closing pressure of the valve opening / closing disk to be more easily adjusted.

일반적으로 웨이퍼형 스윙체크밸브는 플랜지가 없는 구조로서 양측 배관파이 프의 플랜지사이에 삽입설치하여 유체를 한쪽 방향으로만 흐르게 하는 얇은 판상의 밸브를 말하는 것으로, 이러한 웨이퍼형 스윙체크밸브는 도 1에 도시되어 있는 바와 같이 원판형상으로 된 밸브몸체(31)와 밸브몸체(31)의 중앙부에 관통형성된 밸브공(32)의 상단에 힌지식으로 설치되어 유체의 방향에 따라 밸브공(31)을 개폐하게 되는 밸브개폐용 디스크(33)로 구성된다.Generally, wafer type swing check valve is a flangeless structure, which is a thin plate-shaped valve inserted between flanges of both pipe pipes so that fluid flows in only one direction. Such wafer type swing check valve is shown in FIG. As shown in the figure, the valve body 31 is formed in a disc shape and is hingedly installed on the upper end of the valve hole 32 formed through the central portion of the valve body 31 to open and close the valve hole 31 according to the direction of the fluid. The valve opening and closing disk 33 is made.

이와 같이 구성되는 종래의 웨이퍼형 스윙체크밸브는 도 2에 도시되어 있는 바와 같이 배관연결시 연결하고자 하는 양측 배관파이프(40)(41)의 플랜지(40a) (41a)사이에 샌드위치식으로 삽입하므로써 간편하게 설치할 수 있게 된다.The conventional wafer-type swing check valve configured as described above is sandwiched between the flanges 40a and 41a of both pipe pipes 40 and 41 to be connected at the time of pipe connection, as shown in FIG. It is easy to install.

그러나, 상기와 같이 구성되는 종래의 웨이퍼형 스윙체크밸브는 일단 양측 배관파이프(40)(41)의 플랜지(40a)(41a)사이에 설치되고 나면 밸브의 작동여부 및 개폐상태를 외부에서 전혀 확인할 수 없기 때문에 밸브점검시 배관파이프(40)(41)로부터 밸브(30)를 분리해서 점검해야 하므로 밸브(30)의 유지관리에 많은 시간과 노력이 소요되는 문제점이 있었다.However, the conventional wafer-type swing check valve configured as described above, once installed between the flanges 40a and 41a of the both side pipe pipes 40 and 41, checks the operation of the valve and the open / close state at all from the outside. Since it is impossible to check the valve 30 from the pipe pipes 40 and 41 at the time of valve inspection, there is a problem in that it takes a lot of time and effort to maintain the valve 30.

또한, 종래의 웨이퍼형 스윙체크밸브는 운반이나 설치작업을 위해 밸브(30)를 밸브개폐용 디스크(33)가 설치된 쪽으로 기울이거나 눕히게 될 경우 밸브몸체(31)의 내부에 힌지식으로 설치된 밸브개폐용 디스크(33)가 갑자기 회동하면서 주변에 부딪혀 파손될 우려가 있기 때문에 취급이 용이하지 않은 문제점이 있었다.In addition, the conventional wafer-type swing check valve is hinged valve inside the valve body 31 when the valve 30 is tilted or laid down toward the valve opening and closing disc 33 is installed for transport or installation work. Since the opening and closing disk 33 suddenly rotates and hits the periphery, there is a problem that handling is not easy.

또한, 종래의 웨이퍼형 스윙체크밸브는 사용조건에 따라 밸브개폐용 디스크(33)의 개폐압력을 조절하고자 할 경우 배관파이프(40)(41)로부터 밸브(30)를 분리한 후 밸브개폐용 디스크(33)를 다른 밸브개폐용 디스크로 교체해야 하므로 디스 크의 개폐압력조절이 용이하지 못한 문제점이 있었다.In addition, in the conventional wafer type swing check valve, when the valve opening and closing pressure of the valve opening and closing disc 33 is to be adjusted according to the use condition, the valve opening and closing disc is separated after the valve 30 is removed from the pipe pipe 40 and 41. (33) had to be replaced with another valve opening and closing disk, there was a problem that the opening and closing pressure control of the disk was not easy.
