Exhaust apparatus e comprises exhaust pition 16, drain tap 17, exhaust outlet 3, the tenth cavity J.Five-channel 15 is connected the tenth cavity J with the second valve 14 in regulator a.As mentioned above, compressed air in the second cavity I acts on secondary diaphragm M, overcome the power of spring 13, open the second valve 14, compressed air enters into the tenth cavity J by Five-channel 15, promote exhaust pition 16 and open condensed water and 3 discharges of compressed air process exhaust outlet in drain tap 17, the six cavity K.
It is upper that heater c is located at valve body d, and it is for thermal exhaust valve 17 and the second valve 14, in case when temperature is lower, drain tap 17 and the second valve 14 are frozen in, thereby avoids the generation of job failure; On the other hand, also reduce minimum operating temperature of the present invention, increased the adaptability of the present invention to low temperature environment.
Above all parts of the present invention is described in detail, will filter compressed-air actuated flow process and operation principle is described in further detail to the present invention below.
First compressed air enter into the 5th cavity A from air inlet 1, and its temperature declines, the cooling condensed water that becomes of portion of water meeting wherein containing, and this part condensed water enters into the 6th cavity K from the 5th cavity A through first passage L; Remaining compressed air can enter into the 7th cavity B by second channel 2, then by the first through hole 19, enter into annular the 6th channel C of oil strain drying b, through oil-filtering apparatus 4, complete entering into the 3rd cavity D after the filtration of oil content in compressed air.This Partial shrinkage air of oil processing enters into the 8th cavity E through third channel 5 after filtration, then by the second through hole 19-1, enter into drainage drying g, through screen pack 6, complete the filtration to impurity in compressed air, complete and the compressed air of the filtration of impurity is entered into the 4th cavity G of molecular sieve 7 tops by the 7th passage F, the compressed air that enters into the 4th cavity G flows downward, and by molecular sieve 7, completes the filtration to moisture in compressed air.
So far, dual cartridge air dryer has completed the filtration to the oil content in compressed air, impurity and moisture.This Partial shrinkage air enters into the 9th cavity H from molecular sieve 7, the compressed air that enters into the 9th cavity H is divided into four parts: first enters into the 8th passage T from the 9th cavity H, by check valve 8, enter into gas outlet 21, for gas equipment; Second portion enters into the 8th passage T from the 9th cavity H, by check valve 8, enters in throttle orifice 10, acts on primary diaphragm 20; Third part enters into the 8th passage T from the 9th cavity H, by check valve 8, enter in throttle orifice 10, by passage 9-1 after screen pack 9 filters, through valve 18, enter into the first cavity N, along with the compressed air in the first cavity N progressively increases, the air pressure in the first cavity N is also just increasing, the compressed air in the first cavity N to the pressure of primary diaphragm 20 and second portion in compressed air the pressure of primary diaphragm 20 is reached to balance; The 4th part enters into the 8th passage T from the 9th cavity H, then by check valve 8, enters in throttle orifice 10, by four-way 11, enters into the second cavity I.
Above-mentioned first compressed air is exported to gas equipment for it by gas outlet 21, and when exporting to the compressed air of gas equipment by first when too much, 21 places, gas outlet can accumulate a large amount of compressed air, and air pressure herein will increase.In the case, when the air pressure at 21 places, gas outlet reaches predefined numerical value, regulator a starts working, the compressed air being input in the second cavity I by above-mentioned the 4th part promotes the elastic force that secondary diaphragm M overcomes spring 13, open the second valve 14, compressed air in the second cavity I enters into the tenth cavity J of exhaust pition 16 tops by Five-channel 15, promoting exhaust pition 16 moves down, open drain tap 17, gas in the 6th cavity K and condensed water are discharged through exhaust outlet 3, the 5th cavity A subsequently, the 7th cavity B, the 8th cavity E, the 9th cavity H and oil strain drying b, in drainage drying g, compressed air is also discharged from exhaust outlet 3.
Now, because the compressed air in above-mentioned the 5th cavity A, the 7th cavity B, the 8th cavity E, the 9th cavity H and oil strain drying b, drainage drying g is discharged from, its air pressure inside declines, and gas outlet 21 place's air pressure are higher, the compressed air at 21 places, gas outlet enters into drainage drying g via throttle orifice 10, return port 12, the 8th passage T, the 9th cavity H, wash away molecular sieve 7 and screen pack 6, impurity and moisture that previously screen pack 6 and molecular sieve 7 filtered are washed away, by impurity and moisture along with compressed air is discharged from exhaust outlet 3.
Through after above-mentioned flow process, the impurity and the moisture that on screen pack 6 and molecular sieve 7, adhere to are washed, and along with compressed air is discharged from exhaust outlet 3, make molecular sieve 7 regeneration, make molecular sieve 7 keep for a long time the filter effect to moisture, extended the service life of molecular sieve 7.
When the air pressure in gas outlet 21 revert within adjustable range, throttle orifice 10 place's compressed air decline for the active force of primary diaphragm 20, follow this process, and the compressed air in the first cavity N promotes primary diaphragm 20 makes it progressively closed, refluxes and finishes.When brake valve is worked, the air pressure in gas outlet 21 is used up, and when reaching its time and close pressure, the second valve 14 and drain tap 17 are closed respectively under the promotion of spring 13 and exhaust pition 16, and exhaust process stops.
Now, the workflow of dual cartridge air dryer of the present invention has completed a complete circulation, and compressed air, from air inlet 1 input, is opened next circulation afterwards.
The present invention also provides a kind of pneumatic braking system, and it adopts above-mentioned dual cartridge air dryer.
Meanwhile, the present invention also provides a kind of vehicle, and it adopts above-mentioned pneumatic braking system.
By reference to the accompanying drawings the specific embodiment of the present invention is explained in detail above; but the present invention is not limited to above-mentioned embodiment; in the ken possessing those of ordinary skills; can also under the prerequisite that does not depart from aim of the present invention, make various variations, it all belongs to protection scope of the present invention.
