Described pressure regulator valve 7 is provided with an adjusting pressuring knob 33.
In described water supply connector 3, be provided with screen pack 34.
Using method of the present utility model is as follows:
High-pressure wash is confidential while using, and water supply connector 3 is connected with external water source by water pipe, and water out adapter 15 is connected with hydraulic giant by flexible pipe, in the time that jetting machine brings into operation, the current at external water source are in water pipe enters into water supply connector 3, owing to being provided with screen pack in water supply connector 3, therefore the current that enter in water supply connector 3 all can be filtered net 34 by the isolated from contaminants filtration in current, current after being filtered can enter in the inlet triplet for water joint 2 being connected with water supply connector 3, then the inlet pipeline 5 in inlet triplet for water joint enters into Plunger pump body 1, again through Plunger pump body 1 built-in system circulation pressurization, finally flow out from the delivery port 12 of outlet three way joint, enter into water inlet 13 through plunger hole 6, the High-Pressure Water that enters water inlet 13 by self-contained hydraulic pressure by the plug 16 of clogging water inlet 13 originally to the interior promotion of outlet pipeline 14, owing to being provided with back-moving spring 17 between plug 16 and water out adapter 15, therefore in the time that plug 16 is pushed, back-moving spring 17 is extruded, and plug 16 diameters are greater than water inlet 13 diameters, and be less than outlet pipeline 14 diameters, in the time that plug 16 no longer stops up water inlet 13, High-Pressure Water enters into outlet pipeline 14, and enter in the flexible pipe being connected with hydraulic giant by the water out adapter 15 being connected with outlet pipeline 14, final High-Pressure Water sprays from hydraulic giant, now hydraulic giant is open mode, push rod 24 does not apply the pressure backing down to microswitch 26, plunger displacement pump is running status.
In the time that hydraulic giant cuts out, the High-Pressure Water entering in outlet pipeline 14 cannot release to the external world, the moment of hydraulic giant closes, make High-Pressure Water form water hammer effect under the effect of follow-up current, High-Pressure Water rebounds, make back-moving spring 17 reset, plug 16 is stopped up water inlet 13 again, the High-Pressure Water now entering in outlet pipeline 14 cannot reflux from water inlet 13, enter into plunger hole 6 along the auxiliary water route 18 connecting with outlet pipeline 14, and auxiliary water route 18 is all positioned at spacing block 29 tops with port and the first through hole 27 that plunger hole 6 connects, therefore current cannot enter into spacing block 29 belows, now flow in a part of current direction spacing block 29 tops, the current promotion differential plunger 8 mobile to spacing block 29 tops up moves, and differential plunger 8 is pushed pressure spring 9 in upper process of moving, the spool 10 of being located at differential plunger one end starts to depart from gradually vent 11, no longer vent 11 is stopped up, another part current that enter in plunger hole 6 from auxiliary water route 18 enter into stroke hole 19 along the first through hole 27.
Now the pressure in stroke hole 19 becomes large, and the air-flow of stroke hole 19 interior scripts is extruded, the air-flow of extruding enters in delivery port 12 along the second through hole 28, final under the stopping of spacing block 29, enter in vent 11, the air-flow in stroke hole 19 enters into after vent 11, original air pressure moment of stroke hole 19 reduces, the current that enter in stroke hole 19 form stronger hydraulic pressure, two kinds of pressure exist mineralization pressure poor, push rod 24 moment under the effect of pressure is ejected, the shaft 31 of push rod pushes sealing ring 23, because sealing ring 23 is quality of rubber materials, the ejecting force of push rod 24 makes sealing ring 23 that projection occur, 23 of sealing rings after projection can push microswitch 26 makes down circuitry, now plunger displacement pump is out of service, because outlet three way joint 4 is provided with the special stroke hole 19 moving back and forth for push rod 24, therefore push rod 24 structures are short and stable, when being promoted by pressure, push rod 24 can really exert pressure to microswitch 26, there will not be and cause push rod that unstable situation occurs in the time pushing microswitch because push rod is elongated, can in the time that implementing pressure or do not give pressure microswitch, push rod can accurately make microswitch present corresponding state, and without the stability that just can ensure to close rifle arresting gear by two microswitches are set, the pressure that the utility model is implemented push rod is also to utilize the multiple flow passage structures that close rifle arresting gear inside to form, therefore without in the rifle arresting gear of pass, other complicated auxiliary bodies being set, simplify the structure of closing rifle arresting gear, reduce its production cost, and convenient for maintaining, and between push rod 24 and microswitch 26, be provided with sealing ring 23, ensure that microswitch 26 can not be subject to the erosion of current or steam.
In the time that hydraulic giant is opened again, High-Pressure Water in outlet pipeline 14 can spray from hydraulic giant along the flexible pipe being connected with water out adapter 15 again, now differential plunger 8 is also no longer promoted on current direction, under the effect of pressure spring 9, start to reset, again vent 11 is stopped up, enter and also no longer include High-Pressure Water in stroke hole 19, pressure in stroke hole 19 starts to return to initial state, and push rod 24 also starts to reset under the effect that opens and closes spring 25, no longer microswitch 26 is started to exert pressure, the circuit of jetting machine is opened again, therefore in the time transforming under the state that hydraulic giant is opening and closing, there will be above-described job step.
The utility model is in order to extend the service life of jetting machine, in Circuits System, be provided with delay circuit, in the time that microswitch 26 is backed down by push rod 24, plunger displacement pump cuts out wait for five seconds under the effect of delay circuit after, this structure setting is for preventing that staff or other staff from constantly opening or closing hydraulic giant with the character of playing, once this situation occurs, if there is no delay circuit, the Circuits System of plunger displacement pump is too frequently closed or is opened, very easily cause Circuits System to burn out, shorten the service life of jetting machine; And staff can control the flow intensity that hydraulic giant ejects by the adjusting pressuring knob 33 on turn pressure regulator valve; The top of spool 10 is ball head structure, and this structural design more can ensure the sealing of spool 10 in the time stopping up vent 11.
