The utility model has also solved existing cleaning Vehicle water circuit system while changing to nozzle full closing state in working order, pressure regulator valve transfers complete certain reaction time of unloading condition needs to, easily cause the flame-out defect of assistant engine, a kind of high-pressure sewer flushing vehicle water circuit system is provided, without pressure regulator valve off-load, moment is realized backwater, fast response time.
The utility model solves the technical scheme that its technical problem adopts: a kind of high-pressure sewer flushing vehicle water circuit system, comprise the water pump of water tank, connection water tank, the pressure regulator valve of connection water pump, and multiple nozzle actuators of connection pressure regulator valve, system also comprises the two-position four-way valve of multiple parallel connections, a two-position four-way valve of each nozzle actuator series connection, two of two-position four-way valve are respectively C type and J type, between the P mouth of pressure regulator valve and two-position four-way valve, be connected with a pipeline, be directly connected to form pressure release loop by this pipeline water pump and two-position four-way valve.The P mouth that is connected on pressure regulator valve by a pipeline, is directly back to water tank by full-power pressure by two-position four-way valve, without the effect of pressure regulator valve, realizes water route moment backwater off-load, thereby reduces pipeline vibrations, prevents the loss of system components and parts; Do not need the full off-load of pressure regulator valve, just do not need to consider the reaction time of pressure regulator valve yet, just can not cause the assistant engine that connects water pump to stop working, fast response time yet.
As preferably, described pipeline connects the C type position of two-position four-way valve, and the C type position of all two-position four-way valves is interconnected.
As preferably, described pipeline connects the P mouth of one of them two-position four-way valve, the A mouth of this two-position four-way valve connects the P mouth of another one two-position four-way valve, and the A mouth of all two-position four-way valves like this is connected with the P mouth of adjacent two-position four-way valve, and the A mouth of the last two-position four-way valve connects water tank.
As preferably, the A mouth of pressure regulator valve connects the T mouth of two-position four-way valve, between the T mouth of two-position four-way valve, is interconnected, and the B mouth of two-position four-way valve connects nozzle actuator.
As preferably, totally five of two-position four-way valves, nozzle actuator is also five, is respectively left comer spray, front spray frame, right corner spray, dredging shower nozzle and Handheld high-voltage hydraulic giant.Quantity can increase according to specific needs or reduce.
As preferably, water pump adopts high-pressure plunger pump, between high-pressure plunger pump and pressure regulator valve, is connected with Pressure gauge.
As preferably, low water alarm is installed in water tank.Can monitor the water yield of water tank by low water alarm the moment, prevent that water shortage from causing the empty burning of water pump, can remind driver to add water in time simultaneously.
The beneficial effects of the utility model are: the P mouth that is connected on pressure regulator valve by a pipeline, directly full-power pressure is back to water tank by two-position four-way valve, without the effect of pressure regulator valve, realizes water route moment backwater off-load, thereby reduce pipeline vibrations, prevent the loss of system components and parts; Do not need the full off-load of pressure regulator valve, just do not need to consider the reaction time of pressure regulator valve yet, just can not cause the assistant engine that connects water pump to stop working, fast response time yet.
