The plastic flowing valve component is vertically arranged at the lower part of the high voltage end of the YLP08 pump; the end part is connected to the high voltage end of the YLP08 pump; the lower parties connected to the low voltage end of the YLP08 pump; the directly driven contact point jiggling switch component is arranged at the lower end of the plastic flowing valve component. The advantages of the utility model is that the flexible sheet jiggling switch is improved as directly driven type with a reliable work; improving the inlet and outlet water channel position, cancelling the technical hole and blocking head and the sleeve in the copper; the cost is further reduced, which completely solves the problem of leakage by the technical holes.

Description

A kind of jetting machine Direct Action Type shaped plastics closes the rifle arresting gear automatically

Technical field

The utility model relates to a kind of jetting machine Direct Action Type shaped plastics and closes the rifle arresting gear automatically, belongs to the jetting machine technical field.

Background technology

Jetting machine closes the rifle arresting gear as shown in Figure 1, 2 automatically at present; form by YLPO1 pump 1, spring-piece type sensitive switch assembly 2, copper spill valve 3, fabrication hole and plug 4; the copper spill valve 3 horizontal low pressure upper ends of being located at YLPO1 pump 1; right-hand member communicates with the high pressure of YLPO1 pump 1; described spring-piece type sensitive switch assembly 2 is made up of switch enclosure 5, sensitive switch 6, metal clips 7; be located at the left end of copper spill valve 3, described steel spill valve 3 is made up of overflow valve spring 8, copper intermediate sleeve 9, O shape circle 10, copper valve pocket 11 and spool 12.

The right-hand member of copper spill valve 3 communicates with the high pressure of cleaning machine during work, left end communicates with low-pressure area, when cleaning machine is worked, the bind interior nose end of copper valve pocket 11 of 12 of spools, high pressure and low pressure are spaced, when cleaning machine cuts out spray gun, when the pressure of cleaning machine was higher than spring 8 preset pressure, hydraulic pressure was being tried hard to recommend spool 12 to left movement, when spool 12 top external cylindrical surfaces move on to O shape and enclose 10 left position, the higher-pressure region is communicated with low-pressure area, system's overflow, spool 12 promotes metal clips 7 simultaneously, forces sensitive switch 6 actions, the power supply of cut-out system, system dynamic partly quits work; System pressure descends, and spool moves right under the spring force effect to O shape and enclosed 10 o'clock, and system stops release, is in packing state.When cleaning machine was shot once more, system pressure dropped to rapidly near intake pressure, and spool 12 moves to right rapidly and recovers the seat envelope, and metal clips 7 unclamps simultaneously, and micro switch closure, system get electric work, and pressure returns to operating pressure.

The shortcoming that this jetting machine closes the existence of rifle arresting gear automatically is:

1. sensitive switch is a spring-piece type, yielding and misoperation;

2. overflow valve mostly is the copper workpiece, the cost height, and easily the pig copper becomes rusty;

3. unnecessary fabrication hole and plug are arranged on pump, easily leak.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, and cost is low, the jetting machine Direct Action Type shaped plastics of good stability closes the rifle arresting gear automatically.

For realizing above purpose; the technical solution of the utility model provides a kind of jetting machine Direct Action Type shaped plastics and closes the rifle arresting gear automatically; it is characterized in that; form by pump, plastics spill valve, the straight moving contact moving switch module that declines; the plastics spill valve is vertical at the bottom of pump high-pressure side; its end communicates with the pump high-pressure side, and the bottom communicates with the pump low-pressure end, and straight moving contact declines and moves the lower end that switch module is located at the plastics spill valve.

The utility model has the advantages that:

1, the spring-piece type sensitive switch is improved to Direct Action Type, reliable operation;

2, improve structural design, overflow valve copper workpiece changes moulding entirely into, its consistency height, and good stability, cost reduces greatly, is fit to produce in enormous quantities;

3, change the Inlet and outlet water channel position, cancelled fabrication hole and plug and copper intermediate sleeve, cost further reduces, and has thoroughly solved the fabrication hole seepy question.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Embodiment as shown in Figure 3; for the utility model jetting machine Direct Action Type shaped plastics closes rifle arresting gear structural representation automatically; described a kind of jetting machine Direct Action Type shaped plastics closes the rifle arresting gear automatically to be made up of pump 13, plastics spill valve 14, the straight moving contact moving switch module 15 that declines; plastics spill valve 14 is vertically mounted on the bottom of pump 13 high-pressure sides; its end communicates with pump 13 high-pressure sides 24; the bottom communicates with pump 13 low-pressure ends 25; straight moving contact declines and moves the lower end that switch module 15 is installed in plastics spill valve 14, and pump 13 is selected the YLPO8 pump for use.

As shown in Figure 4, for declining with straight moving contact, the plastics spill valve moves the switch module structural representation, described plastics spill valve 14 is made up of plastics valve pocket 16, plastics spool 17, sealing ring 18, spring 19, plastic nut 20, plastics spool 17 is installed in 16 li of plastics valve pockets by sealing ring 18 and plastic nut 20, and mounting spring 19 outside plastics spool 17.

The described straight moving contact moving switch module 15 that declines is made up of box 21, plastic slide block 22, switch 23, switch 23 is installed in 21 li in box, the one end is connected with plastic slide block 22, plastic slide block 22 1 ends contact with plastics spool 17 bottoms, and plastic slide block 22 is the inclined-plane with the contact-making surface of plastics spool 17 bottoms.

The utility model is divided into three states when work

A, be illustrated in figure 4 as the start normal operating conditions, when system works pressure during less than default safe pressure, spring 19 is pushed down plastics spool 17 and is in shown position, and seat is enclosed on the plastics valve pocket 15, and higher-pressure region and low-pressure area are separated.Be independent of each other.

B, as shown in Figure 5, be the utility model overflow situation schematic diagram, when being in closed condition or other improper reason, gun trigger cause system pressure to raise, and during greater than default safe pressure, the pressure that plastics spool 17 overcomes spring 19 moves down, and surmount sealing ring 18, and the higher-pressure region communicates with low-pressure area, and system begins overflow.Plastics spool 17 promotion plastic slide blocks 22 move to right and make switch 23 actions simultaneously, cut off system power supply, and system quits work.

C, as shown in Figure 6; be the automatic pressurize stopped status of the utility model schematic diagram; after system cut-off quits work; pressure further drops to less than behind spring 19 pressure; move back on the plastics spool 17, when sealing ring 18 is sealed plastics spool 17 external cylindrical surfaces, spring force and fluid pressure balance; system stops release, enters the pressurize stopped status.

D, when opening gun trigger once more, system pressure descends rapidly, plastics spool 17 resets, plastic slide block 22 moves to left, system gets electric work, returns to Fig. 4 normal operating conditions.
