Abstract
The utility model relates to a protection device for a high-pressure waterway system, which comprises a high-pressure water pump, a working electromagnetic ball valve, a pressure switch and an unloading electromagnetic pneumatic ball valve, and all the elements are arranged in a waterway. The protection device is characterized in that a pressure regulating valve, a safety valve and a time delay device are further arranged in the waterway. The device is used for solving the problem that when the pressure of the high-pressure waterway system of a high-pressure cleaning vehicle is high, the high pressure can cause damages on the system elements, in particular on the high-pressure water pump.
Description
Technical field
The utility model relates to a kind of high pressure water route system protection device, the high-pressure sewer flushing vehicle high pressure water route system protection device that particularly a kind of road surface is novel.Belong to the special-purpose vehicle field.
Background technology
In recent years, along with the fast development of industry, it is more and more serious that environment pollution seems, environmental issue has been the strategic issue in a whole world.China's 17 Great Councils determine that next five-year plan is the five-year plan of environmental protection.This shows that country more and more payes attention to sanitary improvement, each man of environmental sanitation depot also falls over each other to put out a new product.The environmental sanitation market competition is growing more intense, and high technology content, high value-added product more and more are subjected to user's favor, the special-purpose vehicle that especially gathers multi-function in integral whole.For adapting to the needs that urban environmental hygiene is built, in time clear up urban pavement sandy soil dust, improve air quality, common sprinkling truck is low because of its performance level, function singleness can not adapt to the high standard requirement of people to environmental quality.Therefore the high-pressure sewer flushing vehicle that integrates multiple functions such as low pressure watering, high-pressure wash arises at the historic moment.The high-pressure sewer flushing vehicle high-pressure system comprises high-pressure hydraulic pump (present stage is imported product), nozzle etc.System pressure reaches more than the 10MPa, and the pressure height is big to the system element impact force, and high-pressure hydraulic pump does not allow anhydrous running.Domestic high-pressure sewer flushing vehicle is started late, and model and function are few, though manufacturer of a few family is arranged, the quality of its product and quantity all can not satisfy the needs in market far away.And generally high-pressure system protection is paid little attention to simple approach such as most of employing hypertonia overflow.
Summary of the invention
The utility model provides a kind of high pressure water route system protection device, and it is higher to be used to solve existing high-pressure sewer flushing vehicle high-pressure system pressure, to the particularly infringement that causes of high-pressure hydraulic pump of system element.
For solving the problems of the technologies described above; the technical scheme that the utility model is taked is: a kind of high pressure water route system protection device; comprise high-pressure hydraulic pump, working electromagnet ball valve, pressure switch and off-load electromagnetic pneumatic ball valve; it all is arranged in the water route, it is characterized in that: also be provided with pressure regulator valve, safety valve and delayer in the water route.
Above-mentioned a kind of high pressure water route system protection device between high-pressure hydraulic pump and working electromagnet ball valve, is disposed with safety valve, pressure regulator valve and off-load Solenoid ball valve; Be provided with delayer in each water route, road; The working electromagnet ball valve is connected with delayer by the signal of telecommunication respectively with off-load electromagnetic pneumatic ball valve.
Above-mentioned a kind of high pressure water route system protection device, outgoing signal when pressure switch is used for the water circuit system hypertonia is opened off-load electromagnetic pneumatic ball valve; Pressure regulator valve is used to regulate high pressure water circuit system oil pressure relief; Safety valve is used for regulating the hyperpressure of high pressure water circuit system; Delayer is used for work ball valve and off-load ball valve switch are delayed time, and realizes that the high-pressure hydraulic pump off-load starts, and alleviates the impact of High-Pressure Water to system element.
This device brings into operation, and the pressure switch outgoing signal is opened unloader when the water circuit system hypertonia; Regulate high pressure water route oil pressure relief by pressure regulator valve (overflow valve); Regulate hyperpressure by safety valve.In the control of each road water system, be equipped with delayer, alleviate the impact of High-Pressure Water system element.
Description of drawings
Accompanying drawing 1 is high pressure of the present utility model water route control circuit figure;
Accompanying drawing 2 is a high pressure of the present utility model water route system architecture schematic diagram.
The specific embodiment
Figure of description 1, accompanying drawing 2, pressure regulator valve (overflow valve) 1, safety valve 2, off-load electromagnetic pneumatic ball valve 3, high-pressure hydraulic pump 6 and working electromagnet ball valve 7 are housed in the high pressure water route, pressure switch 4, delayer 5, working electromagnet ball valve 7 and off-load electromagnetic pneumatic ball valve 3 are housed in the control circuit in high pressure water route.When working electromagnet ball valve 7 was in closed condition, 3 of off-load electromagnetic pneumatic ball valves were in open mode, and the water in the pressure duct is in interior recurrent state; When any working electromagnet ball valve 7 switch opens, the work ball valve is opened immediately, and off-load electromagnetic pneumatic ball valve 3 is closed after second through delayers time-delay 2-3 thereupon, has effectively alleviated the impact of High-Pressure Water to system.Pressure regulator valve 1 can be preset certain oil pressure relief P1, and when the hydraulic pressure of pressure duct surpassed P1, water was just by pressure regulator valve 1 overflow, and hydraulic pressure reduces, and remains on a kind of more stable operating pressure state.Pressure switch 4 can be preset certain switch critical pressure P2 equally, and when hydraulic pressure in the high pressure water route surpassed P2, pressure switch 4 was just opened, by 3 off-loads of off-load electromagnetic pneumatic ball valve.Safety valve 2 is higher than the oil pressure relief that the former presets, and (P3＞P2＞P1), hydraulic pressure is too high when the high pressure water route, and when surpassing P3, safety valve 2 is opened, beginning overflow off-load to be preset as P3.Above-mentioned is the triple protection system that is provided with in the high pressure water route.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited to above-mentioned giving an example, and those skilled in the art are in essential scope of the present utility model; the variation of making, remodeling, interpolation or replacement all should belong to protection domain of the present utility model.
