It is dry.
Preferably, being additionally provided with gas outlet on valve body, one end of gas outlet is equipped with the check valve cooperated with gas outlet, humidity
Sensor and pressure sensor are each provided in gas outlet.Facilitate humidity sensor and the direct real-time detection air accumulator of pressure sensor
The state of interior pressure and humidity.
A kind of working method of the automatically controlled drying system of forced refluence, the automatically controlled drying including above-described forced refluence
System further includes following working method, and step 1, the pressure information of pressure sensor acquisition air accumulator simultaneously transmits pressure information
Pressure value is converted to A/D converter and is transmitted to controller；Step 2, controller detects pressure value, when pressure value is less than setting
When pressure value P 1, controller sends enabled instruction to air compressor machine, while opening intake solenoid valve, and air compressor machine passes through drying chamber, valve
Body is inflated to air accumulator；Step 3, when pressure value is greater than setup pressure value P2, controller sends out code to air compressor machine, together
When close intake solenoid valve, open blowback solenoid valve, closing blowback solenoid valve after 10S second.Pressure value P 1 and pressure value P 2 are all provided with
In controller, compare output control instruction by calculating, guarantee the stability of reservoir pressure, by the blowback for opening 10S
Solenoid valve blows to molecular sieve, removes the moisture of molecular sieve, improves the working efficiency of drying chamber, realizes the essence to air inlet
Really control, guarantees the drying of air inlet.
Preferably, further including, step 4, humidity sensor acquires the humidity information in drying chamber and passes humidity information
A/D converter is transported to, humidity information is converted to humidity value and is transmitted to controller by A/D converter；Step 5, controller detects
Humidity value, when humidity value is greater than setting humidity value HR1, controller closes intake solenoid valve, opens Through solenoid valve and blowback
Solenoid valve closes Through solenoid valve and blowback solenoid valve, opens intake solenoid valve when humidity value is less than setting humidity value HR2.
When slow gas leakage or very big Pneumatic braking device gas consumption occurs in gas circuit, blowback needs are not achieved always in the pressure in air accumulator
Pressure value P 2, and drier, due to working long hours, desiccant has reached saturation state and can not absorb excessive moisture, although
Drier is still working at this time, but has lost its effect, and the moisture in air can enter air accumulator, and enter gas circuit
System causes pneumatic device to break down, when the humidity that humidity sensor detection enters air accumulator air is more than setting humidity value
When HR2, controller is closed intake solenoid valve, is removed to molecular sieve air blowing by opening Through solenoid valve and blowback solenoid valve
Water improves the service life of drier and keeps air braking system operation more safe and stable.
The present invention has significant technical effect due to using above technical scheme: when gas circuit occur slow gas leakage or
When Pneumatic braking device gas consumption is very big, blowback needs are not achieved always in the pressure in air accumulator, are detected and are stored up by humidity sensor
Humidity in gas tank, and the moisture in molecular sieve is removed by the opening and closing that controller controls corresponding solenoid valve, it is lowered into gas storage
The humidity of tank gas guarantees the drying of compressed air, and avoiding moisture from entering air-channel system by air accumulator causes pneumatic device to be sent out
Raw failure.
