The utility model also comprises a kind of jetting machine, comprise pump head and microswitch, be provided with overflow valve in the pump head, overflow valve is connected by bar with microswitch, overflow valve is by spool, plug screw, large sealing packing ring, left side sealing ring, left side pad, spring, right pad, right sealing ring, valve pocket, small sealing ring is formed, large sealing packing ring places the outer ring of plug screw, left side sealing ring places the inner ring of plug screw, spool places plug screw, in valve pocket, spool is equipped with spring outward, the two ends of spring are equipped with left pad and right pad, right sealing ring places the inner ring of valve pocket, and valve pocket is equipped with small sealing ring outward, and the top is the endoporus left end that the valve core case of cylinder band one-level circular arc body and one-level cone is enclosed in valve pocket.
The beneficial effects of the utility model are by spool and microswitch interlock, guaranteed the jetting machine working stability, thereby the function of realization low pressure holding to be rational in infrastructure.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model preferred embodiment mesohigh cleaning machine;
Fig. 2 is the structural representation of overflow valve in the utility model preferred embodiment;
Among the figure, 1, spool, 2, plug screw, 3, large sealing packing ring, 4, left sealing ring, 5, left pad, 6, spring, 7, right pad, 8, right sealing ring, 9, valve pocket, 10, small sealing ring, 11, pump head, 12, microswitch, 13, overflow valve, 14, bar.
The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Shown in Fig. 1-2, a kind of jetting machine, comprise pump head 11 and microswitch 12, be provided with overflow valve 13 in the pump head 11, overflow valve 13 is connected by bar 14 with microswitch 12, overflow valve 13 is by spool 1, plug screw 2, large sealing packing ring 3, left side sealing ring 4, left side pad 5, spring 6, right pad 7, right sealing ring 8, valve pocket 9, small sealing ring 10 is formed, large sealing packing ring 3 places the outer ring of plug screw 1, and left sealing ring 4 places the inner ring of plug screw 1, and spool 1 places plug screw 2, in valve pocket 9, the spool 1 outer spring 6 that is equipped with, the two ends of spring 6 are equipped with left pad 5 and right pad 7, and right sealing ring 8 places the inner ring of valve pocket 9, the valve pocket 9 outer small sealing rings 10 that are equipped with.
Select for use the plastics manufacturing by spool 1, plug screw 2, valve pocket 9 make spool 1 be cylinder, in the middle of a step is arranged, the top of spool 1 is enclosed in the endoporus left end of valve pocket 9 for band one-level circular arc body and one-level cone seat.
Outsourcing left side sealing ring 2, left pad 3, large sealing packing ring 3, spring 6, right pad 7, right sealing ring 8, small sealing ring 10.
Large sealing packing ring 3 is enclosed within the outer ring of plug screw 2, sealing ring 4 pads in a left side are at the inner ring of plug screw 2, pack into 2 li of plug screws after loading onto right pad 7, spring 7 and left pad 3 outside the spool 1 step place, with the inner ring of right sealing ring 8 pads at valve pocket 9, the cone seat of the endoporus of valve pocket 9 and spool 1 binds, the valve pocket 9 outer small sealing rings 10. of loading onto
The cleaning machine stress-relief process is as follows:
The right-hand member of overflow valve 13 communicates with the high pressure of cleaning machine, left end communicates with low-pressure area, when cleaning machine is worked, the bind interior nose end of valve pocket 9 of spool 1 head seat, high pressure and low pressure are spaced, when cleaning machine cuts out spray gun, the pressure of cleaning machine is higher than setting pressure, hydraulic pressure is being tried hard to recommend spool 1 to left movement, and when spool 1 top external cylindrical surface moved on to right sealing ring 8 left position, the higher-pressure region was communicated with low-pressure area, system's overflow, spool 1 drives bar 14 rotations simultaneously, and bar 14 drives the power supply that microswitches 12 cut off systems, and system dynamic partly quits work; System pressure descends, spool 1 moves right under the effect of spring 7, when right sealing ring 8 is sealed the external cylindrical surface on spool 1 top, system stops release, be in packing state, spool 1 and valve pocket 10 are by the sealing ring sealing, because the area of the compression area of 1 this moment of spool when sealing greater than seat during pressurize, so the pressure of packing state is lower than operating pressure, this has just realized low pressure holding.When cleaning machine was shot once more, system pressure was reduced to rapidly near intake pressure, spool 1 rapid reset seat envelope, and mobile micro switch 12 closures that make of while spool 1, system gets electric work, and pressure returns to operating pressure.
Though toply illustrate and described the utility model, and do not mean that the utility model only is confined to wherein each kind of details with reference to some specific embodiments and example.On the contrary, on various details, making various modifications with can not departing from the utility model spirit within category that is equivalent to claims and the scope.
