ABSTRACT:
A railway tank car having a wafer-type valve arrangement is provided with a nozzle member. The nozzle member has a mounting portion mounted on the valve arrangement. The mounting portion has an inlet opening therein which is large enough to receive a portion of the wafer valve when the valve is opened. A taper portion is formed integral with the mounting portion, and an outlet portion is formed integral with the taper portion. The outlet portion is smaller than the inlet opening and has securing means thereon for attachment to standard-sized connectors for unloading liquid or semi-liquid cargo. A breakage groove is provided in the nozzle member to protect the valve arrangement from impacts. A steam heating member with steam inlet and outlet means may be placed over the smaller outlet portion and secured to the nozzle member for heating cargo passing therethrough. The taper portion has an indentation therein to facilitate heating of cargo in the nozzle member. Access detents are provided in the steam heating member to allow insertion of bolts in the mounting portion for mounting the nozzle member on the valve arrangement.
