Under first stage working condition, compressed air pressure is less than pressure spring 21 settings, now the air intake valve a closed condition on rubber piston valve 24.Compressed air is entered by K11 mouth, by circular passage D, through the molecular sieve 9 of annular core 10, filter membrane 6 and drying chamber inner bag 8 dry overanxious after, by A chamber, a route K22 mouth, to regeneration air tank air feed, is used during for blowback drying chamber; Check valve 14 is pushed on another road open, by C chamber, to K21 confession gas.
Under second stage working condition, compressed air pressure is greater than pressure spring 21 settings, now the air intake valve A on rubber piston valve 24 is in opening, compressed air enters into the F chamber of unloader, act on diaphragm 27, make diaphragm 27 promote push-plate 28 and off-load valve rod 2, now off-load valve 3 is opened, the compressed air in B chamber enters atmosphere by off-load valve 3 from K3 mouth, unloader doorway sharply declines, regeneration air tank and off-load valve form large pressure reduction, the compressed air of regeneration air tank is by 22 mouthfuls of A chambeies through valve body 13, filter membrane 6, molecular sieve 9, the B chamber of screen pack 10 and valve body, E chamber, off-load valve 3 and silencing net, to 3 mouthfuls, enter atmosphere, complete automatically cleaning flushing circulation.
In valve body 13, be respectively equipped with A chamber, B chamber, C chamber, D annular compartment, E energy-absorbing air flue chamber and F chamber, the side of valve body 12 has first K1, second mouthful of K21, the 3rd mouthful of K22 and four-hole K3, described first K1 is communicated with D annular compartment, D annular compartment is communicated with the outer annular space of drying chamber, the interior annular space of drying chamber is communicated with A chamber, A chamber is communicated with the 3rd mouthful of K22, A chamber is communicated with C chamber by check valve 14, C chamber communicates with second mouthful of K21, C chamber is communicated with pilot-actuated valve by first segment discharge orifice 26, when pilot-actuated valve is opened, gas outlet is communicated with F chamber, F chamber is the diaphragm chamber of unloader, the left side of unloader is B chamber, when unloader is opened, B chamber communicates with E energy-absorbing air flue chamber, the gas outlet of E energy-absorbing air flue chamber is four-hole K3.Pilot-actuated valve is provided with air intake valve a and drain tap b, between described C chamber and the air intake valve a of pilot-actuated valve, is provided with first segment discharge orifice 26, between the air intake valve a of pilot-actuated valve and F chamber, is provided with second section discharge orifice 25; The compressed air of C chamber arrives the air intake valve a of pilot-actuated valve through first segment discharge orifice 26, pressure reaches after the opening pressure of air intake valve a, air intake valve a opens, compressed air is after air intake valve a and second section discharge orifice 25, a part enters F chamber, and another part enters the steam vent f in drain tap b, the 3rd throttle orifice 23 and adjusting seat 18.Described pilot-actuated valve comprises rubber piston 24, and described air intake valve a is located at the left side of rubber piston 24, and drain tap b is located at the right side of rubber piston 24; When rubber piston 24 is positioned at high order end, air intake valve a closes, and drain tap b opens; When rubber piston 24 is positioned at low order end, air intake valve a opens, and drain tap b closes.
Air compressor provides source of the gas, first enter the first K1 of air dryer, compressed air is through the molecular sieve 9 of drying chamber 8, the effect of annular core 10 and filter membrane 6, compressed air is dried, oil removing and filtration treatment, compressed air after processing is from second mouthful of K21 output of air dryer, and by the 3rd mouthful of K22, regeneration air tank is inflated, the compressed air of second mouthful of K21 arrives the air intake valve a of pilot-actuated valve by the first segment discharge orifice 26 of valve body 13 simultaneously, when compressed air pressure reaches unlatching pilot-actuated valve air intake valve a, air intake valve a opens, compressed air is by pilot-actuated valve air intake valve a, after second section discharge orifice 25, a part enters the diaphragm cavity F of unloader.Because pilot-actuated valve drain tap b does not now close, another part compressed air is by pilot-actuated valve the 3rd throttle orifice 23 and steam vent f, because the pressure of diaphragm chamber F is lower, but diaphragm 27 still can promote off-load valve 3 by push-plate 28, and off-load valve 3 is partially opened; The compressed air of regeneration air tank carries out blowback (regeneration) to the molecular sieve 9 in drying chamber 8, and then by the off-load valve 3 partially opening, through energy-absorbing air flue E and silencing net 32, Jiang Shui, oil and impurity enter atmosphere, form exhaust for the first time.
When pilot-actuated valve air intake valve a place pressure continues to rise, the drain tap b of pilot-actuated valve closes (the 3rd throttle orifice 23 pressure release passages are closed) gradually, now the diaphragm chamber F pressure on valve body 13 sharply rises, diaphragm 27 promotes off-load valve 3 by push-plate 28, off-load valve 3 is opened completely, regeneration gas receiver carries out blowback to drying chamber 8 molecular sieves 9 again, forms exhaust for the second time.
When delivery outlet pressure drop is when recovering supply gas pressure, off-load valve 3 is closed, and system is recovered air feed, makes drying chamber 8 molecular sieves 9 reach the object recycling.The compressed air that drying tank 8 is processed, by the 3rd mouthful of K22 of air dryer, enters into corresponding executing agency.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, any scheme after the utility model simple transformation is all belonged to protection domain of the present utility model.
