Regenerating tank cannot carry out blowback, and then drier fails.Moisture in compressed air is entered in braking system component, is influenced
The security of vehicle.
Utility model content：
The utility model is to provide a kind of drier back-blowing device to solve the above-mentioned problems of the prior art.
The utility model adopts the following technical solution：A kind of drier back-blowing device, including inflating pump, condenser, two
Three-way magnetic valve, drier, four-loop protection valve, gas receiver, timer, regenerating tank and double-way check valve, the condenser
One end is connected with inflating pump, and the other end is connected with two-bit triplet solenoid valve, the air inlets of two driers respectively with two-bit triplet
Two gas outlets of solenoid valve are connected, and the gas outlet of two driers corresponds to the air inlet with double-way check valve, four-loop protection valve
Mouth is connected, and the gas outlet of four-loop protection valve is connected respectively with gas receiver, and the back blow port of two driers is connected with regenerating tank, fixed
When device be connected on two-bit triplet solenoid valve.
Further, the two-bit triplet solenoid valve uses closed type Double-control solenoid valve.
The utility model also adopts the following technical scheme that：A kind of drier back-blowing device and its method of work, including as follows
Step：
The first step：After vehicle launch, timer is started to work, and it is 10 points to set the square-wave cycle that timer generates
The time of clock, positive value and negative value is 5 minutes, and the break-make in turn for then controlling the gas outlet of two-bit triplet solenoid valve 3 is 5 minutes；
Second step：No matter whether drier reaches pressure unloading, can all force to carry out automatically controlled off-load, the work of each drier
There was only 5 minutes as the time, the drier that then regenerating tank blowback is stopped, two driers share a regenerating tank no matter
Under which kind of working condition, drier is all in optimum Working.
The utility model has the advantages that：During inflating pump works always, two driers can take turns
Stream works, and ensures no matter when be all drying regime into the compressed air in car air pipe, carry out ensureing vehicle
Security.
Description of the drawings：
Fig. 1 is the utility model structure chart.
Specific embodiment：
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, the utility model discloses a kind of drier back-blowing device, including inflating pump 1, condenser 2, two three
Three-way electromagnetic valve 3, drier 4, four-loop protection valve 5, gas receiver 6, timer, regenerating tank 8 and double-way check valve 9, condenser 2
One end is connected with inflating pump 1, and the other end is connected with two-bit triplet solenoid valve 3, the air inlets of two driers 4 respectively with two three
Two gas outlets of three-way electromagnetic valve 3 are connected, the gas outlets of two driers 4 and double-way check valve 9, four-loop protection valve 5 into
Gas port is connected.The gas outlet of four-loop protection valve 5 is connected respectively with gas receiver 6, back blow port and the regenerating tank 8 of two driers 4
It is connected, timer is connected on two-bit triplet solenoid valve 3.
Timer 7 in the utility model is a kind of microcontroller timer, controls two-bit triplet electric by regulating time
The break-make of magnet valve, timer generate the adjustable square waves of PWM, and the positive value and negative value of square wave are respectively to two controls of two-bit triplet solenoid valve
Device processed is powered.
Two-bit triplet solenoid valve 3 uses closed type Double-control solenoid valve.Two-bit triplet solenoid valve 3 there are one air inlet, two
Gas outlet, air inlet are connected with condenser 2, and gas outlet is connected respectively with two driers 4.Two-bit triplet solenoid valve 3 has note
Recall function, when " crawl " voltage signal is given in one end, this end is opened, and other end is closed, then be connected with unlatching one end
Drier 4 works, and the other end does not work.
The pressure switch of drier 4 is mechanical and electric-controlled type combination.When reaching off-load air pressure, 4 machinery of drier unloads
Lotus.Not up to off-load air pressure when, if drier 4 has off-load signal, 4 automatically controlled off-load of drier.
Inflating pump 1, condenser 2 in the utility model, four-loop protection valve 5, gas receiver 6, regenerating tank 8, bilateral are unidirectional
The operation principle of valve 9 in prior art microbus air braking system inflating pump, condenser, four-loop protection valve, gas receiver,
Regenerating tank, double-way check valve operation principle are identical, therefore no longer the utility model is repeated.
The method of work of the utility model is：
The first step：After vehicle launch, timer is started to work, and it is 10 points to set the square-wave cycle that timer generates
The time of clock, positive value and negative value is 5 minutes, and the break-make in turn for then controlling the gas outlet of two-bit triplet solenoid valve 3 is 5 minutes.
Second step：No matter whether drier reaches pressure unloading, can all force to carry out automatically controlled off-load, the work of each drier
There was only 5 minutes as the time, the drier that then regenerating tank blowback is stopped, two driers share a regenerating tank.No matter
Under which kind of working condition, drier is all in optimum Working.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, several improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
