Specific embodiment

In order to be best understood from the purpose of this utility model, function and specific designing scheme, below in conjunction with the accompanying drawings, to this The automatic pressure regulator of utility model is described in further detail.

As shown in Figure 1, the automatic pressure regulator of the utility model, including appendix 1, one end of the appendix 1 is pasted Ventilated membrane 2, the ventilated membrane 2 are covered by appendix lid 3；Outer cover 5 covers assembled appendix 1, ventilated membrane 2 and gas transmission Pipe lid 3.

Specifically, as shown in Figures 2 and 3, appendix 1 is cylindrical type, centre is equipped with the through-hole of ventilation, and outside is equipped with outer Screw thread, top are equipped with flange, and ventilated membrane 2 is pasted in the flange of appendix 1, and ventilated membrane 2 has ventilative but fluid-tight function, tool Body can select expanded PTFE (ePTFE) material.

As shown in Figure 4 and Figure 5,3 upper end of appendix lid is round cover, and lower end is semicircle cover, the circular lid of upper end Formed fluted between body and the semicircle cover of lower end, groove can be set in one end that ventilated membrane is provided on appendix, limit Position block 8 limits the position of the flange of appendix 1, and in addition appendix lid 3 has air hole 4 in edge.

Outer cover 5 is cylindrical type, interior fluted, there is mounting hole among groove, and appendix sets across mounting hole, is arranged with defeated One end of tracheae lid houses in a groove, the groove madial wall of outer cover and be formed between the lateral wall of appendix lid it is ventilative between Gap.
