Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1 and Figure 2, the pressure reducing valve adapter of even bag respirator disclosed by the utility model, including adjusting group
Part, the adjusting component includes shell 1, and the shell 1 is hollow cylinder, and air inlet is provided on the left of shell 1, and air inlet is connected
There is inlet suction port 2, there is screw thread on 2 inner wall of inlet suction port, there is the gasket being adapted to inlet suction port 2, shell 1 inside inlet suction port 2
Right side is provided with gas outlet, and gas outlet is fixed with air outlet adapter 3, and the air outlet adapter 3 is quick coupling, and quick coupling outer wall has spiral shell
Line shape protrusion, threaded protrusion is the conical surface, and conical surface small end has rotary body 4 towards quick coupling opening direction, 1 inner cavity of shell, rotation
