Further, groove is arranged at described pressure regulation bibcock top, for turning pressure regulation bibcock.
After adopting the program:
When the spring pressure of the air pressure in the first pressure release passage be communicated with pressurized gas higher than floating valve, floating valve upwards ejects, high-pressure air in first pressure release passage is excreted to compressor air inlet machine mouth, to reduce the pressure of pressurized machine mesohigh air via pressure maintaining valve housing bottom end opening, the 1st through hole, the 2nd pressure release passage.When the spring pressure of the high-pressure air in the first pressure release passage lower than floating valve, floating valve closes pressure maintaining valve housing bottom end opening downwards, and pressurized machine mesohigh air keeps original pressure.
The utility model beneficial effect:
A: described spring mattress protection steel ball does not wear and tear by the frictional force of pneumatic spring, to keep the sealed precision of steel ball; Described pressure maintaining valve housing can protect compressor volute not by the frictionally damage rotated frequent in pressure regulator valve bolt adjustment process.
B: the downward pressure suffered by floating valve depends on the pressure of pneumatic spring, the pressure of pneumatic spring depends on that pressure regulation bibcock is screwed into the distance of pressure maintaining valve housing, therefore working condition that can be concrete according to motor, adjusts the pressure of pressurized machine mesohigh air by adjustment pressure regulation bibcock.
C: pressure maintaining valve housing bottom end opening diameter is very little, the force value that pressurized gas are formed at opening is very little, and floating valve adopts the steel ball being placed on pressure maintaining valve enclosure interior, and make the force value triggering pressure release action very little, therefore pressure release action is more sensitive.
