Abstract
PURPOSE: To facilitate pipe connection work or the like, by providing a ball valve and a stopper guide in a valve casing, moving the ball valve by its own gravity along the guiding parts of a stopper guide to stop a flow and providing the stopper guide with fitted parts to restrict the stopper guide.
CONSTITUTION: A valve device is applied to the pipe connection of a split type air conditioner. When 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 valve and the flowing pressure of the coolant and comes into contact with a valve seat 25 to close 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 a valve seat 25 by coolant gas introduced in the direction of an arrow and the passage 24 is opened. At that time, the position of the guide 27 is prevented from deviating due to vibration or the like because the guide 27 has parts 34 fitted in a coolant pipe 16.
