The compressed air condensate drain, further includes clock module, and the clock module connects micro process
The third input terminal of device
In the present embodiment, the upper magnetic level switch 9 and magnetic liquid-level switch 10 are clarinet.First electromagnetism
Valve 5 is normally closed solenoid valve.Clock module is the clock module that 51 series monolithics carry.
The course of work and principle of the utility model are as follows:
When compressed air, which crosses air inlet pipe 2, to be entered in liquid storage container 1, compressed air is got on baffle, in compressed air
Moisture can be accumulated into water droplet, drip in liquid storage container 1 along baffle.
Upper magnetic level switch 9 distinguishes one end with magnetic liquid-level switch 10 and connects high voltage, and the other end concatenates current limliting electricity
It is grounded after resistance.The first input end of 51 series monolithics and the second input terminal are I/O interface, and two I/O interfaces are separately connected
Current-limiting resistance input terminal in 10 circuit of magnetic level switch 9 and magnetic liquid-level switch acquires the electricity of current-limiting resistance input terminal
Pressure.
Liquid level in liquid storage container 1 increases, when annular magnet float 8 is located at upper magnetic level switch 9 and magnetic liquid level
When between switch 10, upper magnetic level switch 9 and magnetic liquid-level switch 10 are off-state, and the first of 51 series monolithics
Input terminal and the voltage of the second input terminal acquisition are low level, and the first output end of 51 series monolithics exports low level, control
The coil losing electricity of the first solenoid valve 5 is made, the first solenoid valve 5 is kept closed.
Liquid level in liquid storage container 1 persistently increases, when annular magnet float 8 is floating at upper magnetic level switch 9, upper magnetic
Property liquid-level switch 9 be attracted, the conducting of the circuit of upper magnetic level switch 9, the voltage that the first input end of 51 series monolithics acquires
It is high level, the voltage of the second input terminal acquisition of 51 series monolithics is low level, and the first of 51 series monolithics is defeated
Outlet exports high level, and the coil of the first solenoid valve 5 of control obtains electric, the first solenoid valve 5 opening, and the liquid in liquid storage container 1 is certainly
The discharge of first drainpipe 4.
As the liquid in liquid storage container 1 is constantly discharged, the liquid level in liquid storage container 1 persistently goes up and down low, works as annular magnet
When float 8 is dropped down at magnetic liquid-level switch 10, magnetic liquid-level switch 10 is attracted, at this point, upper magnetic level switch 9 is opened,
The circuit of magnetic liquid-level switch 10 is connected, and the voltage of the second input terminal acquisition of 51 series monolithics is high level, and first is defeated
The voltage for entering end acquisition is low level.
Since the magnetic liquid-level switch 10 in liquid storage container 1 is not bonded with 1 minimum point of liquid storage container completely, and annular
Magnetic float 8 can be attracted close to magnetic liquid-level switch 10, therefore, when magnetic liquid-level switch 10 is attracted, in liquid storage container 1
Liquid be not completely exhausted out.Since the time of liquid discharge can be evaluated whether, in the clock mould of 51 series monolithics
Under the monitoring of block, 51 the first output ends of series monolithic were delayed after a period of time, exported low level, the first solenoid valve 5 of control
Power loss, the first solenoid valve 5 are closed coil again again, and the liquid in liquid storage container 1 is discharged from the first drainpipe 4, and guarantee storage
Liquid in liquid container 1 is completely exhausted out as far as possible.And so on, the Auto-drainage for realizing water storage container not timing, effectively subtracts
Moisture in few compressed air, is greatly saved labour, is drained when necessary due to being, rather than timing drainage, section
The about energy, brings good economic benefit.
In conclusion the utility model is by upper and lower magnetic level switch monitors water level, microprocessor is according to monitoring result
The folding for controlling the first solenoid valve 5 on the first drainpipe 4 reaches the water storage and automatic drainage function of water storage container, and failure rate
It is lower, securely and reliably.
After preventing liquid from racking up, compressed gas is revealed from the first drainpipe 4, the compressed air condensate discharge
Device further includes U-shaped liquid sealing pipe 11 and the second drainpipe 12, the first draining of side pipe arm connection of the U-shaped liquid sealing pipe 11
The outlet of pipe 4, a side pipe arm of U-shaped liquid sealing pipe 11 connect the import of the second drainpipe 12.Liquid level in U-shaped liquid sealing pipe 11 is lower than
Second drainpipe 12, the hydraulic seal that the outlet of the first drainpipe 4 is accumulated in U-shaped liquid sealing pipe 11 can reduce compressed gas certainly
The leakage of first drainpipe 4, compressed gas pressure reduce, and decrease foreign gas and inversely enter from extraneous through the first drainpipe 4
In compressed gas, guarantee the quality of compressed gas.
The compressed air condensate drain further includes DC power supply and first manual switch;Described first
After 5 coil tandem of manual switch and the first solenoid valve, it is serially connected in DC power supply circuit.Close first manual switch, the first electricity
5 coil of magnet valve obtain it is electric, the first solenoid valve 5 open, can force for the liquid in liquid storage container 1 to be completely exhausted out.First manual switch
Prevented also from microprocessor failure, cause the first solenoid valve 5 that can not open, liquid gathers excessive situation in liquid storage container 1, protects
Liquefied liquid in card compressed air can discharge in time.If deactivating drainage arrangement for a long time, first manual switch is closed,
Ponding in liquid storage container 1 is discharged completely clean.
