本实施例的混凝土泵车气压式水洗系统的工作原理如下：
请参阅图2-4所示，在进行水洗操作时，启动水洗控制盒3水洗操作按键，气压式水洗系统处于加压状态，水洗控制盒3控制第二控制阀7打开，气泵中的高压气体经由第二控制阀7、输气管路2和水洗控制盒3进入水箱4，高压气体给水箱4中的水加压，此时便可通过高压水枪6喷出高压水进行水洗操作。在水洗操作的过程中如果水洗控制盒3中的压力表32收集到输气管路中的压力超过安全值，泄压阀33会自动进行泄压操作，使输气管路2中的压力值回到安全范围以内。在进行加水操作时，启动水洗控制盒加水操作按键，气压式水洗系统处于泄压状态，水箱4中的高压气体排出后，再通过给排水三通阀5的进水口进行加水操作。在车辆正常行驶、转场的过程中，水洗系统处于不工作的状态下，若需要对水箱4的气压进行保压，以便随时可以水洗操作，此时启动水洗控制盒3待洗操作按键，气压式水洗系统处于保压状态下，此时第一控制阀31处于第三工作状态(第一控制阀的出口与截止口连接)，水箱4中的高压气体不会排出，第二控制阀7也会自动关闭，气泵中的高压气体也不会进入到水箱4中，实现保压。
实施例二：

本实施例的混凝土泵车包括上述混凝土泵车气压式水洗系统，该混凝土泵车气压式水洗系统的气源通过输气管路与水箱连接，水洗控制盒设置于所述输气管路上，水洗控制盒包括第一控制阀，第一控制阀具有三种工作状态，在第一工作状态下，气源通过所述第一控制阀与所述水箱连通，使水箱处于加压状态，在第二工作状态下，水箱通过所述第一控制阀与大气连通，使水箱处于泄压状态，在第三工作状态下，水箱通过第一控制阀截止，水箱处于保压状态。本申请混凝土泵车的水洗控制盒具有加压、泄压和保压三种工作状态，能够实现加压控制、压力调节、以及保压等功能，输气管理结构简单、操作方便。
