Referring to fig. 1 to 12, it is illustrated that the explosion-proof and noise-reduction type gas transmission pipe fitting in the present application includes a gas transmission pipe 1, the gas transmission pipe 1 can be mainly used as a carrier for transmitting fluid media, gas resources can be transmitted only by means of the gas transmission pipe 1 due to its special fluidity, and current domestic gas, factory gas and municipal gas can be transmitted without disconnecting pipes, during the process of laying the gas transmission pipe 1, a part of the gas transmission pipe 1 is buried under the outdoor ground, but the pipe is damaged and aged due to being buried under the ground all the year round, when the gas pressure is too high, a transverse shear force to the expansion of the pipe wall of the gas pipe is very likely to occur, and finally, the pipe is cracked due to the fact that the gas transmission pipe cannot bear the shear force, as shown in fig. 3, an explosion-proof assembly is installed in the gas transmission pipe 1, specifically, as shown in fig. 4, the explosion-proof assembly includes a carrier 2 (as fig. 5), as shown in fig. 6, the bearing frame 2 is arranged in a double-ring structure, under normal conditions of air pressure, air flow can pass through the middle of the inner ring of the bearing frame 2 to complete conveying, the baffle 3 is welded between the inner ring and the outer ring of the bearing frame 2, 8 arc-shaped plates 4 are welded on one side of the baffle 3, two adjacent arc-shaped plates 4 are connected in a sliding manner, and the 8 arc-shaped plates 4 jointly form an extensible connection structure; the end of the extensible connecting structure can be in contact with the other side of the baffle 3, and a driving source for driving the extensible connecting structure to extend and retract is arranged on the extensible connecting structure (according to actual design requirements, the driving source can be directly driven by a motor, and the power output end of the motor is welded with the baffle 3 connected to the tail end of the extensible connecting structure, or other commercially available driving equipment is used); when the gas transmission device is used, as shown in fig. 7, the motor rotates to drive the arc-shaped plates 4 at the tail ends of the extensible connecting structures, so that the two adjacent arc-shaped plates 4 are stretched, finally 8 arc-shaped plates 4 are stretched, and the extensible connecting structures formed by continuous combination completely or partially seal the gap between the inner ring and the outer ring of the bearing frame 2, so that the gas flow passing through the pipeline is adjusted according to the air pressure, the increase of the gas flow passing through the gas transmission pipeline 1 in the axial direction is ensured, the impact of the air pressure on the radial wall surface of the gas transmission pipeline 1 is relieved to a certain extent, the shearing force generated by the gas flow on the gas transmission pipeline 1 is reduced, and the phenomenon that the gas transmission pipeline 1 bursts due to the sudden increase of the air pressure is prevented; as a preferred embodiment, in order to accurately measure the air pressure in the gas transmission pipeline 1, a pressure sensor (model: XG-131, not shown in the figure) is installed on the pipe wall of the gas transmission pipeline 1, a preset value is set in a remote controller, once the air pressure exceeds the set value, the pressure sensor immediately transmits a signal to the remote controller, the remote controller receives and analyzes the command, and then sends a rotating command to a motor, so that the gap between the inner ring and the outer ring of the bearing frame 2 can be opened and closed, and the air quantity passing through the pipeline can be accurately adjusted according to the air pressure. Considering that although the impact force generated by the air pressure can avoid the phenomenon of bursting of the air transmission pipeline 1 under the action of the explosion-proof assembly, slight vibration of the air transmission pipeline 1 can still be caused, so that the air transmission pipeline 1 collides with a peripheral fixing support (not shown in the figure) and generates sound, the generated sound easily generates noise and reduces the service life of the peripheral fixing support, and on the basis, a silencing module for preventing the air transmission pipeline 1 from vibrating is installed on the peripheral side wall of the air transmission pipeline 1.

By means of above-mentioned technical scheme, this application is through combining explosion-proof subassembly and assisting there is pressure sensor, thereby can follow the size of air current pressure, in time make the adjustment to explosion-proof subassembly, the radial shear force of atmospheric pressure to gas transmission pipeline 1 production is slowly reduced to the at utmost, releases the pressure that produces in the twinkling of an eye through the mode that increases axial air current cross-section, accomplishes probably to reduce gas transmission pipeline 1 on the source and produces the risk that bursts and initiate the incident.
