Specific embodiment
Specific embodiment of the present utility model is described with reference to the accompanying drawing, it is practical new to better understand this
Type.
High-pressure gas trigger device as shown in Figure 1, including it is packed into hoop 1, sliding sleeve 4, piston 5, air jet pipe 6, high pressure
Air cavity 7, functional threeway 9 and steel ball 17 are filled with the high pressure compressed gas of 12 ± 2MPa into high pressure air cavity 7 by charge valve 11
Body.The front end of sliding sleeve 4 is connect by its external screw thread with hoop 1 is packed into, and the front end for being packed into hoop 1 is connected by the push rod in its axle center
Hole 16 is connect with the putting back-end of impact wave receiving device.Sliding sleeve 4 is sleeved on the excircle of 6 front end of air jet pipe, can before
After slide, 4 tail end diameter of bore of sliding sleeve is small, and diameter of bore is big before tail end, i.e., within rear end and outside air jet pipe 6
Cavity is formed between circular surfaces.Air jet pipe 6 is provided with piston 5, is slidably matched, and 5 front diameter of piston is less than rear portion, 5 tail of piston
It holds fluted, y-shaped ring 13 is housed, there are four radial around the distribution of tube wall cross section even circumferential in air jet pipe 6 middle position
