Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in detail.
As shown in Figures 1 to 5, a kind of automatic blow off valve valve air relief of the present utility model, including electromagnetic valve 1, the valve of described electromagnetic valve 1
Core 11 end connects has valve end cap 2, described valve end cap 2 to be provided with suction nozzle 21, bleed passage 22 and measuring pressure passage 23, described air inlet
Mouth 21 connects with bleed passage 22, measuring pressure passage 23 respectively；The spool 11 of described electromagnetic valve 1 is positioned at suction nozzle 21 and bleed passage
Between 22, the path between suction nozzle 21 and bleed passage 22 can be closed or open in the end of spool 11；Described measuring pressure passage 23
It is provided with pressure test device 3.Initial state electromagnetic valve 1 dead electricity, spool 11 is closed between suction nozzle 21 and bleed passage 22
Path, gas enters measuring pressure passage 23 by suction nozzle 21, pressure test device 3 detection can the current air pressure of continuous detecting, when
Detecting when atmospheric pressure value exceedes setting value, electromagnetic valve 1 is energized, and spool 11 opens leading between suction nozzle 21 and bleed passage 22
Road, gas can be discharged from bleed passage 22；When pressure test device 3 detects that current air pressure falls back to setting value, electricity
Magnet valve 1 dead electricity, spool 11 is re-closing off the path between suction nozzle 21 and bleed passage 22, by said structure principle, passes through
Detected air pressure realizes automatically controlling venting function, and simple in construction, low cost of manufacture.
