一种空气辅助SCR系统用集成式电磁阀
摘要：
本实用新型提供一种空气辅助SCR系统用集成式电磁阀，包括车载压缩空气储气筒，所述车载压缩空气储气筒连接阀体，其特征是：所述阀体内设置有空气过滤器芯，所述空气过滤器芯连接空气开关电磁阀，所述空气开关电磁阀连接定值减压稳压阀，所述定值减压稳压阀连接排空电磁阀，所述排空电磁阀通过尿素泵回路连接尿素喷射器。本方案将空气开关电磁阀、排空电磁阀及一个定值减压稳压阀合理布置在一起，在阀体内通过管路相连，管路短、无管接头、无泄漏。
摘要（英）：

The utility model provides an integrated form solenoid valve for the SCR system is assisted to the air, including on-vehicle compressed air gas receiver, valve body, characterized by are connected to said on-vehicle compressed air gas receiver: in the valve body is provided with the air cleaner core, the air switch solenoid valve is connected to the air cleaner core, definite value decompression surge damping valve is connected to the air switch solenoid valve, the evacuation solenoid valve is connected to definite value decompression surge damping valve, the evacuation solenoid valve passes through urea pump loop connection urea sprayer. Air switch solenoid valve, evacuation solenoid valve and one definite value decompression surge damping valve rational arrangement of are in the same place to this scheme, link to each other pipeline weak point, no coupling, no leakage by the pipeline in the valve body.
