    • Apparatus for connecting a first pre-charged section of an air conditioning system to refrigerant lines connecting the section to a second section of the system. A service unit is employed to connect each refrigerant line to the pre-charge section which includes a body fabricated from a square or rectangular piece of bar stock. A main channel is formed through the bar stock and one end of the main channels is coupled to a suitable system component in the pre-charged section by a tube. A connector having a penetratable seal is mounted in the opposite end of the channel. The connector has a male fitting that is threaded into a female fitting. One fitting is mounted in the opposite end of the main channel and the other fitting is mounted in the refrigerant line. The seal is ruptured or broken when the male fitting is threaded into the female fitting a sufficient depth to establish a leak proof joint therebetween. A process valve is also mounted on the bar stock body and communicates with the main channel via an auxiliary channel. The process valve is used in the factory to charge refrigerant into the section prior to the section being shipped into the field.
    • 用于将空调系统的第一预充电部分连接到将部分连接到系统的第二部分的制冷剂管线的装置。 使用维修单元将每个制冷剂管线连接到预充电部分,该预充电部分包括由正方形或矩形的棒料制成的主体。 主通道通过棒料形成,并且主通道的一端通过管连接到预充电部分中的合适的系统部件。 具有可渗透密封件的连接器安装在通道的相对端。 连接器具有插入阴配件的阳配件。 一个配件安装在主通道的相对端,另一个配件安装在制冷剂管路中。 当阳配件拧入阴配件中时,密封件破裂或破裂,足够的深度在其间建立防漏接头。 过程阀也安装在棒料主体上,并通过辅助通道与主通道连通。 工厂内使用过程阀,将部件运送到现场之前,将制冷剂充入该部分。
