Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.The description only actually at least one exemplary embodiment is illustrative to be never used as to this practicality below
New and its application or any restrictions used.Based on the embodiment in the utility model, those of ordinary skill in the art are not having
There is the every other embodiment made and obtained under the premise of creative work, belong to the scope of the utility model protection.
As shown in Figure 1 to Figure 2, the coolant injection rifle of the present embodiment, includes valve body 1, is set in the top of the valve body 1
There is the first magnetic valve 11 of control device vacuum, the electromagnetism of second solenoid valve 12 and the 3rd is provided with the both sides of the valve body 1
Valve 13, the thimble 14 being additionally provided with the valve body 1 inside valve body 1, one end of the thimble 14 is connected with driving should
In the cylinder 15 of the inside linear reciprocating motion of valve body 1, the cylinder 15 is connected thimble 14 with one end of valve body 1, the valve body 1 it is another
One end is provided with the snap joint 16 for connecting air-conditioning filler line, and the taper knob of cavity is fixedly connected with the lower section of valve body 1
Cylinder 17, has in the internal cavities of handle jacket 17 and fills matchmaker's pipe 18 and vacuum-pumping tube 19, and fills matchmaker's pipe 18 and vacuum-pumping tube 19 is equal
It is connected on valve body 1, the vacuum-pumping tube 19 vacuumizes being turned on and off for action by the control of the first magnetic valve 11, described to fill
Matchmaker's pipe 18 controls filling speed by the magnetic valve 13 of second solenoid valve 12 and the 3rd, and wherein second solenoid valve 12 controls for fast charge, the
Three magnetic valves 13 are controlled for trickle charge, and the other end of refrigerant pipe 18 is connected on refrigerant accumulator (not marked in figure), vacuum-pumping tube
19 other end is connected on vavuum pump (not marked in figure), be additionally provided with valve body 1 for control cylinder 15 open and close by
Button 20, the button 20 are fixed on switch base 23, and switch base 23 is fixedly connected with the side of valve body 1.The snap joint 16
