PIPE CONNECTION VALVE FOR TESTING THE PRESSURE OF AN EVAPORATOR CORE

摘要

The present invention relates to a pipe connection valve for testing pressure, in which a hook-type stopper is arranged such that the stopper is rotatable along the lengthwise direction of a valve body, wherein an end of the stopper is caught by a protrusion formed at the outer surface of the front end of a core nozzle arranged at one side of an evaporator core. The front end of the core nozzle is firmly fixed at the front end of a nozzle hole of the pipe connection valve by means of the hook-type stopper.
