MURPHY CKV / PRV SERIES check valves系列止回阀
CKV系列止回阀是一种直列单向阀，可防止燃油被虹吸回喷油器或喷油泵，从而延迟关闭。CKV series check valves are in-line, one-way valves that prevent fuel from being siphoned back into an injector or injection pump which could delay a shutdown.
止回阀有两种类型：CKV2336和CKV1WPS。CKV2336的每端都有一个1/4 NPT螺纹阳螺纹连接，用于连接燃油管路接头或软管。CKV1WPS止回阀通常安装在最后一个喷油器的燃油旁通管路中。CKV1WPS具有空心螺栓连接和带刺的1/8 NPT连接，用于挠性软管或接头。There are two types of check valves: CKV2336 and CKV1WPS. The CKV2336 has a 1/4 NPT threaded male connection on each end for connecting to fuel line fittings or hoses. The CKV1WPS check valve is typically mounted in the fuel bypass line of the last fuel injector. The CKV1WPS features a hollow bolt connection and a barbed 1/8 NPT connection for flex hose or fitting.
PRV系列减压阀释放燃油系统中的超压，这通常是由关闭燃油电磁阀引起的。The PRV series pressure relief valves relieve overpressure in a fuel system usually caused by closing of a solenoid fuel valve.
PRV50和PRV70的每端都有一个1/4 NPT螺纹连接，用于连接燃油管路接头或软管。The PRV50 and PRV70 have a 1/4 NPT threaded connection on each end for connecting to fuel line fittings or hoses.
