The specific embodiment
As shown in Figures 1 to 8, the spray gun that adopts the utility model amplitude stepless regulator, comprises rifle body 10, is provided with amplitude hole 104 on rifle body 10, amplitude hole 104 connects primary air hole 102 and secondary streams hole 103, and primary air hole 102 is connected respectively air admission hole 101 with secondary streams hole 103; Primary air hole 102 be arranged in parallel with secondary streams hole 103;
On primary air hole 102 and secondary streams hole 103, be provided with amplitude stepless regulator; Amplitude stepless regulator can keep the unimpeded of primary air hole 102, and controls the aperture in secondary streams hole 103;
Unimpeded when primary air hole 102, during 103 cut-off of secondary streams hole, only have primary air 104 outflows from amplitude hole, now formation amplitude is circular air-flow, as shown in Figure 1;
When primary air hole 102 and secondary streams hole 103 is simultaneously unimpeded, air-flow enters from air admission hole 101, and primary air 104 flows out from amplitude hole through primary air hole 102, and secondary streams 104 flows out from amplitude hole through secondary streams hole 103; Due to primary air and secondary streams 104 outflows from amplitude hole simultaneously, now formation amplitude is fan-shaped air-flow, as shown in Figure 5.
As shown in Figure 9, the amplitude stepless regulator of the utility model spray gun comprises adjusting knob 1, regulating valve stem 2, adjustment seat 3, and regulating valve stem 2 is movably set in adjustment seat 3, and the afterbody of regulating valve stem 2 is fixedly connected with adjusting knob 1 by holding screw 5; Between regulating valve stem 2 and adjustment seat 3, be provided with sealing gasket 4; By rotation adjusting knob 1, can drive regulating valve stem 2 with respect to adjustment seat 3 rotations, make regulating valve stem 2 control the aperture in secondary streams hole 103.
Sealing gasket 4 can adopt polyvinyl fluoride, can make the lighter grain husk of feel, soft;
As shown in figure 10, regulating valve stem 2 comprises cylinder shape valve 21, and afterbody 22 end faces of valve body 21 connect holding screw 5; On valve body 21, be disposed with primary air control part 211 and secondary streams control part 212; The head end of valve body 21 is provided with steel bead groove 23, and steel bead groove 23 is for accommodating steel ball 6;
The head of regulating valve stem 2 connects rifle body 10 by steel ball 6; Steel ball 6 is for guaranteeing concentricity;
The cross section of primary air control part 211 is that central angle is less than the fan-shaped of 180 degree, to form primary air groove 2111; The cross section of secondary streams control part 212 is that central angle is greater than the fan-shaped of 180 degree, to form secondary streams groove 2121; Primary air groove 2111 be arranged in parallel with secondary streams groove 2121;
Axially align on the fan-shaped one side of the fan-shaped one side of primary air control part 211 and secondary streams control part 212, makes the fan-shaped another side of the fan-shaped another side of primary air control part 211 and secondary streams control part 212 axially form a breach; The central angle of this breach is 10～90 degree, when amplitude stepless regulator rotation 1/4 circle, can make the aperture in secondary streams hole 103 be adjusted to full-gear from the gradual change of complete shut-down state;
Primary air control part 211 matches with the primary air hole 102 of rifle body 10, and secondary streams control part 212 matches with the secondary streams hole 103 of rifle body 10; Regulating valve stem 2 is in the process of rotation, and the primary air groove 2111 of primary air control part 211 is communicated with primary air hole 102 all the time, makes primary air hole 102 keep unimpeded; Secondary streams control part 212 is blocked secondary streams hole 103, or after regulating valve stem 2 rotation 1/4 circles, the secondary streams groove 2121 of secondary streams control part 212 is communicated with secondary streams hole 103, makes secondary streams hole 103 also unimpeded;
The valve body 21 of regulating valve stem 2 connects rifle body 10 by sealing ring 7, and sealing ring 7 is for separating major and minor air-flow.
Because primary air control part 211 and secondary streams control part 212 are axially forming a breach, when secondary streams control part 212 makes 103 cut-off of secondary streams hole, this breach can make primary air hole 102 still keep unimpeded, and formation amplitude is circular air-flow; By adjusting knob 1, drive regulating valve stem 2 to be rotated counterclockwise 90 degree, make primary air hole 102 and secondary streams hole 103 simultaneously unimpeded, thus make spray gun amplitude by circular air-flow stepless-adjustment to fan-shaped air-flow.
The position of the corresponding regulating valve stem 2 of rifle body 10 is provided with positioning boss, and positioning boss is spacing for regulating valve stem 2 is carried out, and regulating valve stem 2 can only be rotated in the scope of 0～90 degree.
The amplitude stepless regulator of the utility model spray gun can be installed on the rifle body of various models.
