Description

[0001] SEPARABLE TYPE BALL VALVE APPARATUS [0002]

The present invention relates to a detachable ball valve device.

Ball valves are generally used to block fluid flow or to flow fluid. The ball valve has a structure in which pipes are connected to both sides, a ball body for opening and closing is built in the center, and a handle for turning the ball body is provided at the upper end. Ball valves may also be used in refrigeration equipment such as air conditioners.

For example, in the case of an air conditioner, a refrigerator, or the like, the indoor unit and the outdoor unit may be separated from each other. At this time, the refrigerant circulation pipe of the air conditioner and the refrigerating device should be separated from the indoor unit and the outdoor unit. However, if the refrigerant circulation pipe is separated, all the refrigerant in the refrigerant circulation pipe flows out and is difficult to reconnect. That is, separation or connection is not simple.

It may be necessary to isolate the flow path of the fluid not only in the air conditioner and the freezing device but also in other cases. At this time, it is necessary to separate or connect the piping through which the fluid flows simply and safely.
