Direction of axis line touch valve core case stop collar 32 outstanding.
The working principle of the utility model is:
High-pressure pump connector 2 is connected on pump head water outlet, and high pressure water is flowed into outlet valve company by adjusting pressuring valve core 9
Interface 4 overcomes the spring force of cone valve spring 37, and 35 end of cone valve is pushed to open, and high pressure water is flowed into from 35 edge of cone valve
Cone valve inlet opening 36 is simultaneously flowed into cone valve internal hollow channel, then flows into Venturi tube 39, Venturi tube through water outlet connector 38
39 inside form negative pressure, and cleaning agent extraneous at this time is flowed by cleaning agent interface 33, and mix with the water flow of inside and from spray
Head sprays.
First pressure transmission channels 14 are used as pressure communication channel, and the pressure of outlet valve connector 4 is transmitted to pressure regulator valve
Connector 3, middle 8 upper cavity pressure of spacer sleeve is equal with 4 pressure of outlet valve connector, when cleaning machine works normally, flows through cone valve
35 pressure loss is smaller, i.e. about 8 cavity pressure of middle spacer sleeve is approximately equal, since diameter D is greater than diameter d, cleaning machine work
Pressure can with reach following balance, operating pressure P=F/ (S (D)-S (d)), F are the spring force of pressure spring 25, (S (D)-S (d))
For the difference in areas between diameter D and d, joystick knob 24 is screwed, adjustment spring power is exactly to adjust work output pressure.
When cleaning machine gun, cleaning pump is in depressurization phase, fully opens at valve head, and pump head not will form pressure,
Unscrew joystick knob 24, adjusting pressuring valve core 9 moves up, and the gap of pressure regulation valve head 10 and pressuring adjusting valve base 11 increases, until whole fluids from
Connector 5 is bypassed to overflow.Due to not having fluid to flow through cone valve 35, cone valve 35 is bored under the action of 37 spring force of cone valve spring
The Forward of valve spring 37 shuts outlet valve connector 4, in addition cleaning machine has the characteristic of pressure oscillation, keeps in outlet valve connector 4
Crest value is pressed, since minor diameter m is less than diameter d, keeps making on pressure effect adjusting pressuring valve core pedestal 22 in outlet valve connector 4
Adjusting pressuring valve core 9 moves up, and further increases the gap of pressure regulation valve head 10 and pressuring adjusting valve base 11, make in former high-pressure channel water non-resistance from
Bypass connector 5, which unloads, to be spilt out.No pressure in cleaning pump is caused, mitigates cleaning machine line load, reaches off-load purpose.
Middle 8 upper pressure of spacer sleeve is transmitted to pressure by second pressure transmission channels 20 and transmits space 19, then is transmitted to
Third pressure communication channel 21 simultaneously eventually enters into pass rifle pressure chamber 18, pushes touch valve core case 27 to overcome and touches 15 spring of spring
Power touches valve core rod 28 and moves forward, and touches 28 bottom of valve core rod and position change occurs for touch switch 17, movement is formed to touch and be opened
The electric signal of pass, after the pin of touch switch connects cleaning machine, which, which can control cleaning mechanomotive force, stops.
It when reopening spray gun, keeps pressure to disappear in outlet valve connector 4, touches spool 16 and touching spring 15
Under spring-force driven dual, the adjusting pressuring valve core body of rod 23, which moves down, withstands touch switch 17, and the electric signal of touch switch 17 makes cleaning machine again
Work, when cleaning machine works, the front and back pressure for touching spool 16 is equal, and maintenance and 17 contact condition of touch switch clean motor-driven
The sustainable work of power.
