Description

[0001] The present invention relates to an internal monitoring type disk valve,

.

[TECHNICAL FIELD OF THE INVENTION AND RELATED ART OF THE SAME]

The present invention relates to a disc valve that can be internally observed.

A disc valve (a so-called butterfly valve) or a gate valve is mainly used on a large-sized pipe for transporting various kinds of fluids over a long distance in order to control the supply or cutoff of the fluid or the supply amount of the fluid. There was no way to observe or check the state of the inside of the body and to observe whether or not the fluid flowed smoothly in the pipeline. There was no method of checking whether leakage occurred when the disk or gate was blocking the pipeline. And there is no way to observe or confirm it, which is an obstacle to efficient fluid transportation.

Patent Publication No. 10-0999419 discloses that a ball valve for forming a complicated structure of a camera unit operation housing in a valve body and preventing fluid from entering the camera unit is separately installed in a camera unit operation housing, The apparatus is also installed separately in the housing, so that the above-described ball valve is opened and the camera unit is vertically lowered by operating the camera unit driving device so that the inside of the pipe can be photographed.

However, this is not preferable because the structure is complicated and inconvenient to use, and the possibility of occurrence of failure is high, which is not good. Also, the manufacturing cost is increased due to the complicated structure, which is not only economical but also difficult to replace parts. In order to clean the camera unit, There is a problem that it is inconvenient to disassemble a part of the unit operation housing and the camera unit driving device and it is difficult to obtain a clear image because there is no explanation that the light function is provided or a structure display is not provided. It is a separate technology that has a clear difference between structure and operation, usage tips, maintainability, usability, light function, and so on.

Next, in the case of Patent Document No. 10-2006-0115981, it is a patented technology of the present invention that a hole is formed in a protrusion for supporting a lower end portion of a stem to be assembled to a valve body, and a transparent window is inserted in the hole, There was a closed end almost impossible to observe the inside of the pipeline, which is different from the present invention in all respects.

Next, in the case of Patent Publication No. 10-2009-0117480, a transparent pipe is provided on a valve pipe for confirming the flow action of the refrigerant flowing in the expansion valve for a refrigeration apparatus. Which are different in purpose and different in structure and function.

In the case of Patent Publication No. 1999-0037364, a cylinder connected to a hydraulic device located on the ground, a piston connected to the hydraulic device, a resilient hose connected to the piston, and a camera connected to the supporting hose, The present invention also relates to a separate technique which differs from the present invention in the purpose of the invention and in structure and function.
