Abstract
PURPOSE: To automatically close a ball valve and facilitate pipe connection work or the like, by providing the ball valve and a stopper guide in a valve casing and by moving the ball valve by its own gravity along the guiding parts of the stopper guide.
CONSTITUTION: A valve device is applied to the pipe connection of a split air conditioner. When connecting pipes 19, 20 are removed from low-pressure valve units 17, 18 in the displacement or shipment of the air conditioner, the flowing-out of a coolant through an outlet port 23 is prevented because each ball valve 26 rolls and moves down along the guiding parts 29 of a stopper guide 27 due to the gravity of the ball valve and the flowing pressure of the coolant and comes into contact with a valve seat 25 to shut off a passage 24. When the pipes 19, 20 are connected to the valve units 17, 18 in installation and a compressor 14 is driven, each ball valve 26 is separated from the valve seat 25 by coolant gas introduced in the direction of an arrow and the passage 24 is opened.
