Pneumatic launcher with novel gas way system

The invention discloses a pneumatic launcher with a novel gas way system. The pneumatic launcher comprises a gun barrel, a gas chamber, a control device, a high-pressure gas bottle and a projectile, the control device comprises a pneumatic quick-opening valve connecting the gun barrel with the gas chamber, a three-way joint mounted on the pneumatic quick-opening valve, a launching valve mounted on the three-way joint, and a pressure reducing valve, and an inflation valve is mounted on the high-pressure gas bottle and connected with the pressure reducing valve through a hose. When the high-pressure gas bottle inflates the gas chamber, the pneumatic quick-opening valve and the launching valve are closed, and after the inflation valve is opened, high-pressure gas in the high-pressure gas bottle enters the gas chamber; when pressure in the pneumatic quick-opening valve reaches preset pressure, the pressure reducing valve is automatically closed; during launching, the inflation valve is closed firstly, the launching valve is opened secondly, high-pressure gas in the pneumatic quick-opening valve is quickly released, a valve core is quickly opened under drive of pressure of the gas chamber, and the high-pressure gas in the gas chamber quickly enters the gun barrel through a valve port and drives the projectile to be launched. The pneumatic launcher is simple in structure, controllable in gas pressure, adjustable in launching distance, large in launching load and high in launching efficiency.
