Background technology
The Vehicular air treater provides complete, cleaning, actv. air for systems such as automobile brake, car door and suspensions, and is very big to the safety traffic and the influence in brake system life-span of automobile.The Vehicular air treater is the fabricate block of dry air filter and multifunction valve, and the dry air filter cleans the pressurized air from Air compressor and be dry, and multifunction valve is used for restriction and protection system pressure.The dry air filter is the prerequisite of air processor normal operation in the Vehicular air treater, is related to the safety of automobile brake and driving.
But the priority valve of dry air filter adopts diaphragm type structure in the Vehicular air treater in the past, exists the not too accurate and failure-free problem of valve opening and closing control, and then has influence on the response rapidity and the reliability of Vehicular air treater.In addition, the main valve of dry air filter adopts skeleton and rubber valve fabricated structure in the Vehicular air treater in the past, and complex structure, reliability are not high, and service life is not long yet.
The utility model content
For the priority valve valve opening that overcomes dry air filter in the existing Vehicular air treater and closing control not too accurately with reliable, and the deficiency that main valve adopts complexity, the reliability of skeleton and rubber valve fabricated structure not high, service life is not long yet, the utility model proposes a kind of dry air filtration device structure that adopts the piston pilot-operated type.The valve opening of this dry air filter and closing control are more accurate and reliable than diaphragm type guide mode, and service life is also longer, structure more in the past in the Vehicular air processing unit dry air filter more simple with reliably, service life is also longer.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of automobile-used non-maintaining type air processor comprises filter and priority valve, and detailed process is that priority valve is the piston cylinder operator priority valve.
In concrete the enforcement, priority valve comprises end cap, piston valve, spring, exhausr port, steel ball, plastic piston, seal ring, and spool, pressure spring, lower spring cup, cover plate, set screw, interference is connected piston valve with steel ball, is provided with spring between end cap and steel ball; Pressure spring is located in the lower spring cup, and set screw is spun on the cover plate, and the set screw end withstands on down on the pressure spring, and spring perch withstands on piston, is provided with spool in the piston, and spool withstands on the steel ball.The piston cylinder operator priority valve comprises that pressure spring and piston constitute a ring of guide's control, set up normal air feed circuit pressure; Second ring that the guide who adopts hollow push rod and piston to constitute controls, the automatically cleaning flushing initial pressure of setting dry air filter.
In concrete the enforcement, the dry air filter is a drying chamber, and molecular sieve is housed in the drying chamber.
In concrete the enforcement, drying chamber comprises cylinder barrel, circuit, plastics inner bag, felt circle and connecting panel, and connecting panel is provided with aperture, and drying chamber is connected with valve seal by rectangular seal.
In concrete the enforcement, piston valve adopts the whole sulfuration of rubber and plastic skeleton, structure more in the past in the Vehicular air processing unit dry air filter more simple and reliably, service life is also longer.
The beneficial effects of the utility model are: valve opening and closing control are more accurate and reliable, and service life is also longer.And the piston valve of this dry air filter to adopt rubber and plastic skeleton be that integral body is vulcanized, structure Vehicular air device for drying and filtering more in the past is more simple and reliable, service life is also longer, has improved the overall performance of Vehicular air treater, has improved braking and traveling security.

The specific embodiment
According to structure as shown in Figure 1, the embodiment of concrete non-maintaining type air filtration dryer is described as follows.
Drying chamber is by cylinder barrel 1, circuit 2, plastics inner bag 3, molecular sieve 4, and felt circle 5 and connecting panel 6 are formed, and are connected with valve body 10 isolating seals by rectangular seal 7.
Multi-functional pilot-actuated valve is by end cap 12, piston valve 11, spring 13, exhausr port 14, steel ball 15, plastic piston 16, seal ring 17, spool 18, pressure spring 19, lower spring cup 20, cover plate 21, and set screw 22 constitutes.Piston valve 11 adopts that rubber and plastic skeleton are whole to be vulcanized, and seal ring 17 is a V-shaped seal ring, is located in the groove of circumference of plastic piston 16, seals, and 15 interference are connected piston valve 11 with steel ball, and 15 of end cap 12 and steel balls are provided with spring 13; Pressure spring 19 is located in the lower spring cup 20, and set screw is spun on the cover plate 21, and the set screw end withstands on down on the pressure spring 19, and spring perch 20 withstands on plastic piston 16, is provided with spool 18 in the plastic piston 16, and spool 18 withstands on the steel ball 15.
Under the F/s service condition, compressed air pressure is less than pressure spring 19 settings, and the air extractor vent on the spool 18 can't conducting at this moment.This moment, pressurized air was entered by admission port 8, and by the aperture on chamber A, the connecting panel 6, behind molecular sieve 4 filtration dryings in felt circle 5 and chamber B, a route air tank admission port 26 uses during for automatically cleaning to the air tank air feed; Check valve 9 is pushed on another road open, to air extractor duct 1, air extractor duct 2 24 and air extractor duct 3 25 air feed of three air extractor ducts.
Under the subordinate phase service condition, compressed air pressure is greater than pressure spring 19 settings, and the ventilation sky on the spool 18 is with conducting at this moment, and piston valve 11 will be unlocked.At this moment, because reducing of air feed side air pressure, cause air tank internal gas pressure height, form one back draught, by air tank admission port 26 via aperture on the molecular sieve in the B of chamber 4, felt circle 5, the connecting panel 6 and chamber A, by the piston valve of opening 11, discharge to exhausr port 14, finish self-cleaning function.
In addition, piston valve 11 and spring 13 also constitute a safety valve, to prevent the F/s air pressure fluctuation in when work.
