Description
Technical field
The present invention relates to motor vehicle braking system field, specially a kind of air dryer systems for oil-field special vehicle.
Background technology
Section components are consumable accessory or the part for requiring periodic replacement in air dryer unit, such as regularly replace and be air-dried
Cylinder, winter severe cold season need to fill alcohol etc. in deicing pump.Oil-field special vehicle is a kind of special special purpose vehicle field, such car
Field work is generally lain in, and most operating locations are apart from cities and towns several hundred kilometers barren hill or desert region.This spy
Different field of operation is maintained in condition and is extremely difficult to for this replacing part and filling.But brakes is to ensure complete machine again
The most important system of driving safety.
The content of the invention
The invention provides a kind of air dryer systems for oil-field special vehicle, solve operation under the particular surroundings such as field
Oil-field special vehicle brakes in the problem of section components have damaged or have been not easy to maintenance and repair in air dryer unit.
Technical program of the present invention lies in：Including the first air dryer unit, the second air dryer unit, reversal valve and shuttle
Valve, the reversal valve include an air inlet and two gas outlets, and first air dryer unit and second is air-dried list
The air inlet of member connects a gas outlet of reversal valve each via pipeline, and the first air dryer unit and second is air-dried list
The gas outlet of member connects the air inlet of shuttle valve by pipeline respectively, and the reversal valve air inlet connects air compressor, and shuttle valve goes out
Gas port connects motor vehicle braking system.
Preferably, the reversal valve is hand-operated direction valve.
The beneficial effects of the present invention are：Said system is simple in construction, easy to operate, and list is air-dried by setting two sets
Member, the compressed air that can be fully dried with effective guarantee motor vehicle braking system, is ensured the driving safety of vehicle, is easy to vehicle
Maintenance and repair.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
As shown in figure 1, the structure of the present embodiment include the first air dryer unit 3, the second air dryer unit 4, manually
Reversal valve 1 and shuttle valve 2, reversal valve include an air inlet and two gas outlets, and the first air dryer unit 3 and the second air are done
The air inlet of dry unit 4 connects a gas outlet of hand-operated direction valve 1, the first air dryer unit 3 and each via pipeline
The gas outlet of two air dryer units 4 connects the air inlet of shuttle valve 2 by pipeline respectively, and the connection of the air inlet of hand-operated direction valve 1 is empty
Air compressor, the gas outlet of shuttle valve 2 connection motor vehicle braking system.
Above-mentioned air dryer unit includes air dryer, regeneration gas receiver, deicing pump.Manual reverse of direction valve air gate leads to
Pipeline is crossed to be connected on the air dryer air inlet of two air dryer units, air dryer simultaneously with regeneration gas receiver and
Deicing pump connects, and deicing pump is connected to the air inlet of shuttle valve by pipeline.
The operation principle of said system is：
The air inlet of hand-operated direction valve receives the compressed gas from air compressor and gone out by two of hand-operated direction valve
Arrived respectively after gas port and be connected to the first air dryer unit and the second air dryer unit.First air dryer unit and the second air
The gas outlet of drying unit connects shuttle valve by pipeline, the outlet connection motor vehicle braking system of shuttle valve, supplies and compresses to brakes
Air.Under normal circumstances, operation hand-operated direction valve makes the compressed air from air compressor enter after hand-operated direction valve
First air dryer unit 1, then enter shuttle valve via the gas outlet of the first air dryer unit, then supplied by shuttle valve gas outlet
To motor vehicle braking system；When failures such as the generation part of the first air dryer unit 1 failures, manual switching hand-operated direction valve, make
Compressed air from air compressor enters the second air dryer unit 2, compressed air through another gas outlet of hand-operated direction valve
Shuttle valve is entered by the gas outlet of the second air dryer unit again, then supply vehicle brakes compressed air.
As seen from the above, when a set of air dryer unit generation part is damaged and can not worked, operation can be passed through
Compressed air is switched in dedicated air drying unit (i.e. the second air dryer unit) by hand-operated direction valve, is done by dedicated air
Dry unit provides fully dry air for brakes.
The system architecture is simple, easy to operate, and the normal operation of vehicle can be effectively ensured, and improves vehicle driving safety
Property.
The preferred embodiments of the present invention are these are only, are not intended to limit the invention, for those skilled in the art
For member, the present invention can have various modifications and variations.Any modification within the spirit and principles of the invention, being made,
Equivalent substitution, improvement etc., should be included in the scope of the protection.
