Abstract
The utility model is related to a kind of sprinkling trucks; by increasing unloading valve on sprinkling truck pipeline; it is not switched in pipeline blockage, outlet valve, failures such as water pump overspeed operation or when maloperation; protect loine pressure always in 1.2Mpa or less; it avoids causing line seals damage, pipeline drainage; it avoids causing power takeoff, water pump vane and oil sealing damage; power takeoff and water pump are the core components on sprinkling truck; it breaks down if the two is any; then sprinkling truck can not operation; increase maintenance cost, influences vehicle use.Meanwhile return pipe is set after unloading valve, when superpressure off-load discharges water, flow returns water tank, saves water resource.This pipeline automatic protective system is of low cost, simple in structure, flexible form, is easily installed and promotes, and can be installed additional on sprinkling truck and cleaning vehicle pipeline, and protection water pump, pipeline and power takeoff extend sprinkling truck service life and save water-saving.
Description
Technical field
The utility model is related to a kind of sprinkling trucks, belong to environmental sanitation vehicles technical field.
Background technology
It is power source that sprinkling truck, which mostly uses chassis power takeoff, both at home and abroad at present, and driving water pump works, and water pump mostly uses
Centrifugal principle, water are rotated by impeller, are sprayed with certain pressure by special operation pipeline, are completed operation of keeping a public place clean of sprinkling water,
Its pressure is generally in 1.2Mpa or less.Since water pump is without protective arrangement for limiting output voltage, when blocking occurs for operating pipeline, water outlet ball valve is not beaten
It opens, in the case of water pump overspeed operation or other maloperations, pipeline inner pressure can be increased drastically, when pressure is more than pipeline pressure voltage
When, drainage can occur for most weak location in pipeline, and easily cause the damages such as water pump, power takeoff, line seals, increase dimension
Expense is repaiied, vehicle use is influenced.
Utility model content
The purpose of this utility model is to provide a kind of sprinkling truck, when solving pipeline inner pressure more than pressure voltage, damage
The problem of watering component.
To achieve the above object, the embodiment of the utility model includes：
A kind of sprinkling truck of the utility model, including following scheme：
Scheme one, including chassis, the chassis are equipped with the tank body for water storage, and the tank body is connected with pressure piping,
One end of the pressure piping is equipped with sprinkler tip, and the water pump for establishing hydraulic pressure, the pipe are provided on the pressure piping
On the road, it is provided with unloading valve on the pipeline at water pump water-storage end.
This programme can occur blocking in pipeline, water pump overspeed operation or water outlet ball valve such as are not switched at the maloperations,
When overpressure is more than certain numerical value, unloading valve opens off-load, effectively prevent the damage of pipeline.
Scheme two, on the basis of scheme one, the unloading valve passes through tank body described in piping connection.
Water storage tank body is connected by pipeline after unloading valve, when unloading valve opening discharges water off-load, water is flowed again by pipeline
Water storage tank body is returned, can not be wasted water.
Scheme three, on the basis of scheme one or scheme two, the unloading valve is pressure-adjustable unloading valves.
Using unloading valve, the threshold value for the off-load that makes to discharge water in pipe can be adjusted as needed.
Scheme four, on the basis of scheme three, on the pipeline, side of the water pump far from water pot is provided with pressure gauge.
Scheme five, on the basis of scheme four, the water pump is connected by transmission shaft with chassis power takeoff.
Scheme six further includes preshoot nozzle on the basis of scheme five, and the sprinkler tip includes preshoot nozzle.
Scheme seven spills nozzle on the basis of scheme six after further including, the sprinkler tip spills nozzle after including.
Scheme eight further includes water cannon nozzle on the basis of scheme seven, and the pipeline is also connected with water cannon nozzle.
Description of the drawings
Fig. 1 is the utility model sprinkling truck pipeline schematic diagram.
Specific implementation mode
The utility model is described in more detail below in conjunction with the accompanying drawings.
A kind of sprinkling truck pipeline schematic diagram as shown in Figure 1, including water storage tank body 1, water pump 2, water pressure gauge 3, pipeline 4, unload
Lotus valve 5, return pipe 6.4 one end of pipeline connects water storage tank body 1 by water pump 2, and 4 other end of pipeline is divided into two, and one connects forward
Connect sprinkling truck preshoot nozzle, another to nozzle and water cannon nozzle is spilt after connection, water pump 2 is fixed under chassis member
Portion is connected by transmission shaft with power takeoff.On pipeline 4, water pump 2 to preshoot nozzle, after spill nozzle and water cannon nozzle it
Meta position installs a bypass line, and the bypass line end set has pressure-adjustable unloading valves 5, another end interface of unloading valve
On be connected to water return pipeline, the water return pipeline connection water storage tank body 1.Preferably, the bypass line is set to the water pump 2 and goes out
At the mouth of a river.On pipeline 4, water pump 2 to preshoot nozzle, after spill between nozzle and water cannon nozzle, be additionally provided with water pressure gauge 3,
For showing pipeline inner pressure.As other embodiment, pressure-adjustable unloading valves may be used in unloading valve 5, can be arranged as required to
Pipeline off-load threshold value (i.e. the protection pressure of pipeline).Unloading valve 5 triggers off-load threshold value and generally should be 1.2Mpa, protects pipeline internal pressure
Power is always in 1.2Mpa or less.
When sprinkling truck works, water pump 2 starts, and is not switched on if there is pipeline blockage, water pump overspeed operation or water storage ball valve
When the case where failure or maloperation, when pressure value is more than the protection pressure of setting, pressure limiting device is opened in unloading valve, and part water is logical
It crosses return pipe 7 and flows back to tank body, protection pipeline inner pressure is always below protection pressure.
The utility model by sprinkling truck pipeline increase pressure automatic protective system, pipeline blockage, outlet valve not
When in the case of the failures such as opening, water pump overspeed operation or maloperation, protection loine pressure is always in 1.2Mpa hereinafter, avoid causing
Line seals damage, pipeline drainage avoid causing power takeoff, water pump vane and oil sealing damage, and power takeoff and water pump are
The core component on sprinkling truck breaks down if the two is any, sprinkling truck can not operation, increase maintenance cost, influencing vehicle makes
With.
This pipeline automatic protective system is of low cost, simple in structure, flexible form, is easily installed and promotes, and can sprinkle water
It is installed additional on vehicle and cleaning vehicle pipeline, protection water pump, pipeline and power takeoff extend sprinkling truck service life.
