Embodiment 1
[0022] The low-pressure waterway of the sanitation vehicle with adjustable flushing width of the present invention, such as figure 1 As shown, it includes water tank 1, water pump 2, throttle valve 3, pneumatic cut-off valve 4, sprinkler 5, control air circuit 6 and connecting pipeline, etc. The power is provided by the power take-off port of the chassis 7 of the sanitation vehicle. The water outlet of the water pump 2 is connected to one or more sprinklers 5 through the connecting pipeline. The throttle valve 3 and the water channel cut-off valve 4 are connected in series, and the bypass water channel is finally connected to the water tank 1 .
[0023] A shut-off valve 8 can be arranged between the water outlet of the water pump 2 and the sprinkler 5, and the shut-off valve 8 can be controlled by automatic control methods such as air control.
[0024] When the low-pressure water circuit is in normal operation, the pneumatic cut-off valve 4 on each bypass water circuit is clo...
Embodiment 2
[0028] On the basis of Example 1, in other embodiments, the flow control valve 9 with electric proportional adjustment can also be used in the bypass waterway to conduct waterway on-off and flow control to realize fine control, instead of the throttle valve 3 and the pneumatic cut-off valve 4. The flow control valve with electric proportional adjustment can change the flow rate by using electric control adjustment, instead of the function realized in the case of multiple bypass water circuits in Example 1, such as figure 2 . Others are the same as in Example 1.
