Description
Technical field
The utility model belongs to cleaning equipment technical field, refers in particular to a kind of high-pressure cleaning device.
Background technology
High-pressure cleaning device provides power by motor or engine, and power is delivered in the pump housing by crankcase, makes
Piston reciprocation motion in the pump housing, produces high pressure, the water in the pump housing is formed water under high pressure and is sprayed, and reaches the purpose of cleaning.
During cleaning, control whether water sprays by spray gun.Conventional high-pressure cleaning device, after cleaning is finished, spray gun is closed
Close, then manual shut-down, and this period before shutdown, high-pressure cleaning device works on, and pressure continues to increase in the pump housing,
If shut down not in time, the load capacity of the pump housing can be exceeded, cause device damage or produce other dangerous.
The content of the invention
The purpose of this utility model is to provide a kind of high-pressure cleaning device of the completion automatic stopping when spray gun is closed.
What the purpose of this utility model was realized in：A kind of high-pressure cleaning device, including crankcase and the pump housing, both it
Between by plunger connect, water supply connector and water out adapter are provided with the pump housing, wherein, be provided with pressure regulator valve on the pump housing
With control valve, the pressure regulator valve is connected with the water out adapter, described to control to be provided with mozzle between valve and the pressure regulator valve,
The pressure regulator valve is provided with pressure threshold value, after hydraulic pressure exceedes threshold values, current by mozzle flow direction control valve, the control valve
End is provided with microswitch, and control valve produces displacement under the impact of current, so as to start microswitch, realizes shutting down.
A kind of high-pressure cleaning device mentioned above, wherein, the pressure regulator valve is knob, can set pressure threshold value.
A kind of high-pressure cleaning device mentioned above, wherein, pressure gauge, the pressure gauge and institute are provided with the pump housing
The pump chamber connection of the pump housing is stated, the pressure value in pump chamber can be effectively monitored by pressure gauge.
A kind of high-pressure cleaning device mentioned above, wherein, the crankcase is internally provided with bent axle, is set on the bent axle
Crank is equipped with, the plunger at one end is hinged with the crank, and the other end is extended in the pump chamber of the pump housing.
The utility model is prominent and beneficial compared to existing technology to be had the technical effect that：It is used during being discharged by water under high pressure
Property, a backflow for super-pressure can be produced when closing suddenly, the high-pressure water of backflow exceedes the pressure threshold value of pressure regulator valve, makes to surpass
Water under high pressure flow direction control valve, so as to start microswitch, realizes autostop, prevents not shutdown in time, and pump housing continuous firing is made
It is exceeded into the pressure in the pump housing, damage equipment or produce other dangerous, safe operation is improve, extend the use longevity of equipment
Life.

Joint, wherein, pressure regulator valve and control valve are provided with the pump housing, the pressure regulator valve is connected with the water out adapter, the control
Mozzle is provided between valve processed and the pressure regulator valve, the pressure regulator valve is provided with pressure threshold value, after hydraulic pressure exceedes threshold values, current
By mozzle flow direction control valve, the end of the control valve is provided with microswitch, used during being discharged by water under high pressure
Property, a backflow for super-pressure can be produced when closing suddenly, the high-pressure water of backflow exceedes the pressure threshold value of pressure regulator valve, makes
High-pressure water flow direction control valve, control valve produces displacement under the impact of current, so as to start microswitch, realization stops automatically
Machine, prevents shutdown in time, and pump housing continuous firing causes the pressure in the pump housing exceeded, damage equipment or produces other dangerous, carries
Safe operation high, extends the service life of equipment.
Further optimization, the pressure regulator valve is knob, can quickly set pressure threshold value.
Further optimization, is provided with pressure gauge on the pump housing, and the pressure gauge is connected with the pump chamber of the pump housing, passed through
Pressure gauge can effectively monitor the pressure value in pump chamber.
Further optimization, the crankcase is internally provided with bent axle, crank, the plunger at one end is provided with the bent axle
It is hinged with the crank, the other end is extended in the pump chamber of the pump housing.
Above-described embodiment is only preferred embodiment of the present utility model, and protection model of the present utility model is not limited according to this
Enclose, therefore：All equivalence changes done according to structure of the present utility model, shape, principle, all should be covered by protection of the present utility model
