Abstract
The utility model discloses a high pressure waterway control unit, including at least one working waterway hydrovalve. The water inlet of each hydrovalve is communicated with the outlet of a high pressure water pump, while the water outlet is communicated with each cleaner. The utility model is characterized in that the working waterway hydrovalve is connected in parallel with a high pressure water pump outloading hydrovalve whose on-off action is opposite to the working waterway hydrovalve, the high pressure water pump outloading hydrovalve and each working waterway hydrovalve are all high pressure ball valves, the control arms arranged on which are respectively connected with an air cylinder which can control the movement of the high pressure ball valves or a hydraulic cylinder piston rod. The structure design of the utility model is simple, the high pressure water pump outloading hydrovalve and the working waterway hydrovalve can be controlled to take a reversed on-off action when the water pump starts and the working waterway hydrovalve switches over by utilizing the air cylinder and the hydraulic cylinder, thus reducing the impact of the start to the water pump and the transmission agent, prolonging the service life of the water pump, and avoiding the water pump locked-rotor phenomena which can happen in the process of switching over the working waterway hydrovalve, thereby the opening frequency of the water pressure safety valve is reduced, and the utility model can be widely applied to various water pump drive type cleaning vehicles.
Description
Technical field:
The utility model relates to the road cleaning and uses cleaning Vehicle, is specifically related to the improvement of high pressure water route control gear on the cleaning Vehicle.
Background technique:
At present; the high pressure water route control gear of cleaning Vehicle mainly contains dual mode both at home and abroad: the first is made up of water pressure safety valve, buffering accumulated energy device and work water route water valve, and the starting-impact that nozzle resistance produces when starting of pump station mainly relies on buffering accumulated energy device and water pressure safety valve protection water pump and water pump transmission system.This control mode, though suffered impact can reduce starting of pump station the time, the buffering accumulated energy device is installed inconvenient, the cost height, and can not eliminate the water pump stall problem that may occur in the operation; It two is made up of water pressure safety valve and work water route water valve, though this mode is simple, but can make the water pump starting under load, generation is to the impact of water pump and water pump transmission system (when water pump is hydraulic driving, hydraulic system can absorb a part of impact load), and be difficult for eliminating the water pump stall problem that may occur in the operation.
The model utility content:
Technical problem to be solved in the utility model is the impact of how avoiding starting of pump station and being produced when work water route water valve switches, and eliminates the water pump stall phenomenon that may occur in the operation.
The utility model is to solve the problems of the technologies described above by following technological scheme.It comprises one or more work water route water valves, each water valve water intake is communicated with the high-pressure water pump outlet, water outlet is communicated with each washing unit, it is characterized in that being arranged in parallel on the water valve of described work water route the switching motion high-pressure water pump off-load water valve opposite with it, high-pressure water pump off-load water valve and each work water route water valve is high-pressure ball valve, and set control arm joins with the cylinder or the hydraulic cylinder piston rod of its action of may command respectively on it.
The utility model structural design is simple, make opposite switching motion at starting of pump station and when work water route water valve switches by utilizing cylinder or oil hydraulic cylinder control high-pressure water pump off-load water valve and work water route water valve, reduced the impact of starting to water pump and transmission system, prolonged the life-span of water pump, the water pump stall phenomenon of having avoided work water route water valve in handoff procedure, may occur simultaneously, reduce the unlatching number of times of water pressure safety valve, can be widely used in the cleaning Vehicle of various water pump driving types.
Description of drawings:
Fig. 1 is the utility model structural front view;
Fig. 2 is the utility model structure plan view.
Among the figure:
1-high-pressure water pump off-load water valve; 2-work water route water valve;
3-cylinder or oil hydraulic cylinder.
Embodiment:
As shown in Figure 1 and Figure 2, the utility model comprises one or more work water route water valves 2, each water valve is arranged in parallel, its water intake is communicated with the high-pressure water pump outlet, water outlet is communicated with each washing unit, it is characterized in that being arranged in parallel on the described work water route water valve 2 a high-pressure water pump off-load water valve 1, this water valve water intake is communicated with the high-pressure water pump outlet, and water outlet is communicated with water tank.High-pressure water pump off-load water valve 1 and each work water route water valve 2 are high-pressure ball valve, and set control arm is hinged with cylinder or oil hydraulic cylinder 3 upper piston rods respectively on it.The utility model mainly is to make different switching motions with high-pressure water pump off-load water valve 1 at synchronization and realize its technique effect by cylinder or the oil hydraulic cylinder 3 controls water route water valve 2 of respectively working.As shown in the figure, when each work water route water valve 2 cuts out or during starting of pump station, when the water route water valve 2 of promptly working is swung to the right by diagram direction of arrow control arm, high-pressure water pump off-load water valve 1 is opened, be that high-pressure water pump off-load water valve 1 is swung left by diagram direction of arrow control arm, pump outlet is communicated with water tank, the water pump off-load, thereby can reduce to start the time to the impact of whole system; When arbitrary work water route water valve 2 was opened, high-pressure water pump off-load water valve 1 control arm was done under the control of cylinder or oil hydraulic cylinder 3 and the opposite action of work water route water valve 2 control arms, and high-pressure water pump off-load water valve 1 cuts out automatically.
Claims (2)
1, a kind of high pressure water route control gear, it comprises one or more work water route water valves, each water valve water intake is communicated with the high-pressure water pump outlet, water outlet is communicated with each washing unit, it is characterized in that being arranged in parallel on the water valve of described work water route the switching motion high-pressure water pump off-load water valve opposite with it, set control arm joins with the cylinder or the hydraulic cylinder piston rod of its action of may command respectively on the water valve of high-pressure water pump off-load water valve and each work water route.
2, high pressure according to claim 1 water route control gear is characterized in that high-pressure water pump off-load water valve and each work water route water valve are high-pressure ball valve.
