Description

Wash width adjustable sanitation car low pressure water route
Technical Field
The invention relates to the field of sanitation vehicles, in particular to a low-pressure waterway system for a sanitation vehicle.
Background
In the scheme of the existing low-pressure waterway system of the sanitation truck, a centrifugal water pump is adopted to pump clear water from a vehicle-mounted water tank, a water outlet of the water pump is connected with a sprinkler through a cut-off valve or directly, and the water pump is driven by a chassis power take-off mechanism. When the sanitation truck with the structure works, the flushing width of the sprinkler is only determined by the rotating speed of the water pump, and because the water pump is driven by the chassis power take-off mechanism and is limited by the running requirement of the chassis, the chassis engine and the gearbox need to operate at proper rotating speed, the flushing width of the sprinkler cannot be effectively adjusted. When the sanitation car meets the roadside and has pedestrians or other working conditions that the washing width needs to be adjusted, the use requirement cannot be met.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide the sanitation vehicle low-pressure waterway with adjustable flushing width, so that the flushing width of the sanitation vehicle low-pressure waterway can be adjusted in real time, and the application scene of the sanitation vehicle low-pressure waterway is expanded.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
a low-pressure water channel of a sanitation truck with adjustable flushing width comprises a water tank, a water pump, a sprinkler and a bypass water channel;
the water tank is connected with a water inlet of the water pump through a connecting pipeline, and a water outlet of the water pump is connected with one or more sprinklers through a connecting pipeline;
a bypass waterway capable of controlling opening and closing is arranged between the water outlet of the water pump and the water tank.
Further, the bypass waterway comprises a throttle valve and a waterway shut-off valve which are connected in series.
Furthermore, the bypass water path is controlled to be on or off by a pneumatic, hydraulic or electric control mode.
Furthermore, a stop valve capable of controlling the on-off is arranged between the water outlet of the water pump and the sprinkler.
Furthermore, the cut-off valve is controlled to be switched on or off in a pneumatic, hydraulic or electric control mode.
Further, the bypass waterway is provided as one or more than one.
Furthermore, the bypass water paths are arranged to be multiple, and the throttle valve on each bypass water path is provided with different throttle opening degrees.
Further, the bypass water path is controlled by an electrically proportional regulated flow control valve.
Furthermore, the water pump is powered by a power take-off port of the chassis of the sanitation truck.
The invention achieves the following beneficial effects:
according to the sanitation truck low-pressure water channel with the adjustable flushing width, the bypass water channel is additionally arranged at the water outlet of the water pump of the low-pressure water channel, when the low-pressure water channel normally runs, the bypass water channel is closed, the water pump normally supplies water to each sprinkler through the pipeline, and when the water spraying pressure needs to be changed, the bypass water channel can be controlled to be opened, so that the pressure at the sprinkler is changed, the real-time adjustment of the flushing width of the low-pressure water channel of the sanitation truck is realized, and the application scene of the low-pressure.

fig. 2 is a schematic view of a low-pressure water path of the sanitation truck with adjustable flushing width in embodiment 2.
Detailed Description
The invention is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
Example 1
The invention discloses a sanitation truck low-pressure water path with adjustable flushing width, which comprises a water tank 1, a water pump 2, a throttle valve 3, a pneumatic stop valve 4, a sprinkler 5, a control gas path 6, a connecting pipeline and the like, wherein the water tank 1 is connected with a water inlet of the water pump 2 through the connecting pipeline, power of the water pump 2 is provided by a power taking port of a chassis 7 of the sanitation truck, a water outlet of the water pump 2 is connected with one or more sprinklers 5 through the connecting pipeline, a bypass water path is arranged at a water outlet of the water pump 2 of the low-pressure water path, the throttle valve 3 and the water path stop valve 4 are arranged on the bypass water path, the throttle valve 3 and the water path stop valve 4 are connected in series.
A stop valve 8 can be arranged between the water outlet of the water pump 2 and the sprinkler 5, and the stop valve 8 can be controlled to be switched on and off by automatic control modes such as pneumatic control and the like.
When the low pressure water route normally operated, pneumatic trip valve 4 on each bypass water route was closed, and water pump 2 normally supplied water for sprinkler 5 through the pipeline, when needs changed and washed the width, automatic control's pneumatic trip valve 4 was opened, made partial discharge return to the water tank through the bypass water route to change 5 pressures on the sprinkler, and then change and wash the width.
The bypass water path with the combination of the throttle valve 3 and the pneumatic cut-off valve 4 can be provided with a plurality of bypass water paths, and the throttle valve 3 on each bypass water path can be respectively provided with different throttle opening degrees.
The pneumatic cut-off valve 4 and the cut-off valve 8 can be controlled to be on or off by the control gas circuit 6 in a pneumatic control automatic control mode.
Example 2
On the basis of embodiment 1, in other embodiments, an electric proportional control flow control valve 9 may be further used in the bypass water path to perform water path on-off and flow control, so as to achieve fine control, instead of the combination of the throttle valve 3 and the pneumatic cut-off valve 4, and the electric proportional control flow control valve may change the flow rate by using electric control adjustment, instead of the function achieved in the case of multiple bypass water paths in example 1, as shown in fig. 2. The rest is the same as in example 1.
