Embodiment 1
[0113] An assembled lead-sealed gas blaster, such as figure 1 As shown, it includes an inner tube 1, an inner tube filling cavity 2, an ignition mechanism 3, an inner tube inflation mechanism 4a and an outer tube 5, the inner tube 1 is an inner tube filling cavity 2, and the two ends of the inner tube 1 are respectively sealed and connected with The first sealing inner cover 6a and the second sealing inner cover 6b, the outer layer of the inner tube 1 is the outer tube 5, and the first sealing outer cover 7a and the second sealing outer cover 7b are sealingly connected between the inner tube 1 and the outer tube 5 , the first sealing cover 7a and the second sealing cover 7b are located at both ends of the outer tube 5,
[0114] The sealed cavity between the inner tube 1 and the outer tube 5 is the outer tube filling cavity 8, and the inner tube filling cavity 2 is filled with a reducing agent and an oxidizing agent, and the oxidizing agent is supercritical oxygen, high-pressur...
Embodiment 2
[0129] The difference with embodiment 1 is: as Figure 4 As shown, the ignition mechanism 3 includes a heating wire 311, a wire 312, a wire through hole 313 and a sealing base 314, the heating wire 311 is connected to the wire 312, and the axial center of the sealing base 314 is a wire through hole 313, and the wire 312 is wrapped through the insulating layer. Wire perforation 313; the upper end of the wire perforation 313 is an internally threaded hole 3131, and an internal sealing rubber ring 3132 is installed at the bottom of the internally threaded hole 3131. The internally threaded hole 3131 is matched with a perforating screw 3133, and the axis of the perforating screw 3133 is provided with a perforation, and the wire 312 passes through the inner sealing rubber ring 3132 and the perforated screw 3133, and the perforating screw 3133 cooperates with the internal thread hole 3131 to press the inner sealing rubber ring 3132 to seal the wire hole 313; the outer wall of the sea...
Embodiment 3
[0131] The difference with embodiment 1 is: as Figure 5 As shown, the inner tube 1 includes a first segmented body 11 and a second segmented body 12, the first segmented body 11 and the second segmented body 12 are connected through a threaded structure, and are matched with a threaded sealing ring 13 for Sealing; the first sealing inner cover 6a and the second sealing inner cover 6b are respectively connected to both sides of the first segment body 11 and the second segment body 11; this structure is convenient for charging.
