Description of drawings:
The drier outer casing bottom can be fixed together with screw thread and casing ontology (2), is enhanced leaktightness, establishes seal ring (28) between connecting, and drier is a double-decker, shell (31) be about around the top be one.Desiccant (34) is housed in the inner core (1), be provided with filtering net (35) for outer tube (30), skin in tin (30) between inner casing (32) and the shell (31), blowdown chamber (25) is that casing ontology (2) forms, top is provided with narrow meshed cover plate (29), the blowdown chamber is communicated with the lower end of the outer tube of drier (30) through the aperture of cover plate (29), the top of outer tube (30) is communicated with the top of inner core (1), and the lower end of inner core has pipeline to be communicated with equilibrium reflux device and regulator.
The structure of regulator is: the outside of set screw (10) is with adjusting screw(rod) (11), there is spring (37) on the top, tip of screw (10), the other end of spring (37) withstands on the piston (15), screw rod (11) most advanced and sophisticated with form blow off valve (14) between an end of piston (15) becomes, form air inlet valve (16) between the other end of piston (15) and pipeline (17) port, the other end of pipeline (17) has pipeline (23) to be connected with the upper chamber (22) of blowdown piston (21) with the left air chamber of pipeline (24) piston (15).
The structure of blowdown part is: lower end, blowdown chamber (25) is communicated with the lower chamber of blowdown piston (21), and it is foul valve (20) that the lower end of blowdown piston (21) has between a spring (38) and its lower chamber, and the other end of spring is at an end of engine housing (2).The lower end in blowdown chamber (25) is communicated with exhaust tube through foul valve (20), and the exhaust tube other end is outlet, high muffler plate (19) on the exhaust tube.
Embodiment: the admission port (27) that enters air dryer when the pressurized air that contains moisture content, impurity and greasy dirt of air compressor output, enter blowdown chamber (25), the outer tube (30) of going into drier when rising aperture in the cover plate (29) again is through filtering net (35), and Ye Tai moisture and most greasy dirt and impurity are near blowdown chamber (25) inflow foul valves (20) after filtration.The preliminary filtered air of warp enters inner core (1) top by the top of outer tube (30), and the downward desiccant (34) that flows into wherein, airborne moisture is adsorbed, the air of dry decontamination enters pipeline (3) through pipeline (a 33) part, open check valve (26) and enter pipeline (24), output in the air receiver by air extractor duct (13); Another part in the pipeline (33) purifies air and enters the air chamber of dummy piston (7) left and right side through cutoff port (4) and pipeline (6).Because cutoff port (4) is thinner than pipeline (6), along with the gas that enters in the air receiver through air extractor duct (13) from pipeline (24) increases, increased pressure, pressurized air is pushed piston (15) to move to right to through pipeline (17) when pressure reaches pressure unloading, opened air inlet valve (16), closed blow off valve (14) gradually, at this moment, pressurized air has been opened foul valve (20) through entering the top air chamber (22) of blowdown piston (21) and promote piston (21) thereby move down through piping (23), make the water that deposits bottom, blowdown chamber (25) in, greasy dirt and impurity enter blow-off pipe (18) and are discharged by sewage draining exit, at this moment air compressor begins off-load, pressure in the pipeline (3) is die-offed, check valve (26) is closed, while dummy piston (a 7) left side, the air chamber on right side is respectively by cutoff port (4) and pipeline (6) venting release, because the diameter of pipeline (6) is than big many of cutoff port (4), make dummy piston (7) right side air chamber release fast, pressure is relatively little, piston (7) is moved to right, air inlet valve (5) is opened, this moment, the dried compressed air in the air receiver was through backflow cutoff port (8) significantly after the throttling step-down, rise by air inlet valve (5) back, enter in the dryer inner core (1) through pipeline (33), dry compressed gas is taken away the moisture in inner core (1) internal desiccant again, form water flow back into blowdown chamber through filter screen (30) and enter foul valve (20), the regeneration of desiccant is handled thereby finished.When air receiver depress drop to certain value after, relief piston (15) is promoted left by the effect of spring (37) again, close air inlet valve (16), open blow off valve (14), at this moment, air chamber (22) communicates with atmosphere with air extractor vent (12) on the adjusting screw(rod) (11) through pipeline (23), air chamber (22) release, move in blowdown piston (21) resilience, foul valve (20) is closed, and this moment, Air compressor began air feed again.Air enters pipeline (33) along drier, dummy piston (7) and arranged on left and right sides air chamber boosts by cutoff port (4) and pipeline (6) inflation respectively simultaneously, because right air chamber step-up ratio left side air chamber is fast, press overbalance relatively, promoting piston (7) moves to left, close air inlet valve (5), the air dryer reflux course promptly ends.Pressurized air is opened check valve (26) again, and air dryer enters into next working cycle again.The size of above-mentioned backflow knothole (8) is controlled by set screw (9).
Advantage of the present utility model is a lot, be actually monotubular formula air dryer, owing to adjusting pressuring valve core, backflow dummy piston and blowdown piston all can be contained in the casing ontology of casting, only the drier shell be connected on the corresponding casing ontology and get final product, so complete function not only, use reliably, compact conformation, volume is little, cost is low, be convenient to install, can be widely used on medium-sized and the heavy motor vehicle, more be applicable to and manually put on the motorcoach of taking advantage of.
