When fan main body 100 outage state; as shown in Figure 5; switch 105-2 disconnects; electromagnet 105-1 dead electricity; spool 105-6 exists; passage under the effect of reset spring 105-5 between closedown suction port 105-3 and air outlet 105-7; now air outlet 105-7 communicates with relief opening 105-4; therefore the gas circuit of the air bag 102-5 of atmospheric valve 102 inside is communicated with air; contraction state is at the thrust lower gasbag 102-5 of spring 102-7; shutoff dish 102-3 is in open mode under the effect of spring 102-7, and the outlet of fan main body 100 directly communicates with ambient atmosphere.
After fan main body 100 starts, exit flow is put in air by the interstitial row between shutoff dish 102-3 and threeway 102-2, when the rotating speed of fan main body 100 meets the requirements of working speed, the switch of described two-bit triplet solenoid valve 105 closes, as shown in Figure 6, electromagnet 105-1 obtains electric, spool 105-6 moves right, the yellow 105-5 of compression reset, and the passage of closing between air outlet 105-7 and relief opening 105-4, passage between suction port 105-3 and air outlet 105-7 is opened, part exit flow slowly enters in air bag 102-5 by tracheae throttle valve 104 and two-bit triplet solenoid valve 105 by air bag suction port 102-10, air bag 102-5 is expanded, promote push rod 102-4 to be gradually moved to the left, according to equilibrium of forces principle, shutoff dish 102-3 and seal ring 102-1 is finally made to fit completely, fan main body 100 outlet pressure is higher than the pressure in pipeline this moment, air-flow is discharged from aerated conduit 107.
At stop moment, two-bit triplet solenoid valve before air bag suction port 102-10 cuts out instantaneously, the outlet of air bag 102-5 and fan main body 100 is disconnected, air bag 102-5 communicates with air simultaneously, now in air bag 102-5 gas pressure higher than ambient atmos pressure, gas flows into air rapidly from air bag 102-5, air bag 102-5 pressure drop, push rod 102-4 moves right under the effect of both sides pressure reduction and spring 102-7, shutoff dish 102-3 and seal ring 102-1 is disconnected instantaneously, fan main body 100 exit flow is put in air by this interstitial row, cause fan main body 100 outlet pressure sharply to decline and the check valve on aerated conduit 107 is closed, when in air bag 102-5, pressure is identical with barometric pressure, atmospheric valve 102 reaches initial position, until fan main body 100 is out of service.In addition; rely on two-bit triplet solenoid valve 105 to disconnect (i.e. solenoid valve power-off) and realize owing to shutting down emptying This move; even if illustrate that the blower suddenly power-off that is in operation also can make the action of emptying, the running protection of blower is greatly improved.
Described non-loaded start and stop emptying system not only structure, control simple, and the air bag of atmospheric valve adopts the outlet blast of blower fan as source of the gas, does not need complicated external air source control gear, utilizes the exhaust outlet pressure of blower own just can drive, avoid using external air source, Security reliability is high.
The non-loaded start and stop of air suspension centrifugal blower rely on exhaust-valve open closedown to realize, be first in emptying state after requiring blower fan starting up in actual conditions environment, now fan outlet is connected with air, and blower fan is in no-load condition.According to onsite application environment, slowly closing emptier when reaching rotating speed or the pressure of setting also proceeds to load, until reach the pressure range of setting.This object be prevent blower fan load instantaneously the electric current caused too high and occur surge.Because aerated conduit outlet side pressure is higher than fan outlet side pressure during shutdown, this can cause air to occur backflow phenomena under the effect of water.Need fast discharging, during unloading, the rotating speed of blower fan and pressure decline fast.Emptier is opened fast simultaneously, is worked by the only valve that returns on exhaust-valve and aerated conduit simultaneously.Prevent that blower fan instantaneous pressure is unbalance causes air inversion phenomenon, and prevent liquid from damaging blower fan by pipeline backflow.
The pipeline configuration of described atmospheric valve is simple, easy to operate, and required drive is the pressurized gas that blower produces, and economical and reliability is all significantly improved.
