Specific implementation method

Seeing Fig. 1, Fig. 2, the main body of this utility model flue electric check valve is a cylindric antireverse valve spool 4, an electrical appliance kit 5 is fixed in its side, and its bottom is socketed in base 8.The inner chamber of antireverse valve spool 4 is equipped with one The air door page plate 6 that block is made up of circular metal plate or plastic plate.Air door page plate 6 outer rim is provided with two relative location Rotating shaft 7, air door page plate 6 is fixed in the inner chamber of antireverse valve spool 4 by two positioning rotating shafts 7.Positioning rotating shaft 7 with Locating shaft boss 9 pivoting that antireverse valve spool 4 barrel extenal fixation is arranged connects (as shown in Figure 3).Air door page plate Being cased with a sealing ring 14 on 6, play the effect improving tightness, it makes air door page plate 6 be in closedown shape Keep between inner chamber and the inner chamber of base 8 of antireverse valve spool 4 during state sealing.

Fig. 4 is base 8 schematic diagram, and base 8 is made up of the cylinder of integral type and peripheral square plate.Base 8 can It is connected with antireverse valve spool 4 by cylinder side, it is also possible to be connected with antireverse valve spool 4 by square plate side.At Fig. 1-figure In embodiment shown in 4, base 8 can be connected with antireverse valve spool 4 by square plate side.At square plate near middle Cylinder position has two relative drawstring positioning ports 10, is equipped with drawstring 11, drawstring on drawstring positioning port 10 11 are made by having resilient nylon material, and shown in its shape as Fig. 5-1,5-2, one end of drawstring 11 is curved Hook-shaped, both sides indentation, mid portion is groove, has a herringbone strong point at the middle part of groove.

Electrical appliance kit 5 is built with supply socket 1 and electric-controlled plate 3, and electric-controlled plate 3 is provided with D.C mutual-inductor 12 and list Sheet machine 13.As shown in Figure 6, supply socket 1 accesses indoor 220V power supply, and its power supply supplies motor 2 and exchanges Transformer 12.D.C mutual-inductor 12 is connected with single-chip microcomputer 13, and the control line of single-chip microcomputer 13 is connected to motor 2, The positioning rotating shaft 7 of the rotary shaft linkage air door page plate 6 of motor 2, positioning rotating shaft 7 drives air door page plate 6 to rotate. Air door page plate 6 is to be controlled opening and closing action by motor 2.

The circuit diagram of D.C mutual-inductor 12 and single-chip microcomputer 13 embodiment, as shown in Fig. 7, Fig. 8, it should be noted that, They are not limited to the circuit form disclosed in two figures, actually have multiple circuit or the D.C mutual-inductor of model, list Sheet machine can be applied in this flue electric check valve, as long as can serve the same role.

Shown in Fig. 9 is this utility model schematic diagram of being arranged in smoke exhaust ventilator flue, in figure it will be seen that its Installation form is identical with existing check (non-return) valve.

Utility model works process is: when the fan starting key of unlatching smoke exhaust ventilator, when blower fan is started working, have Bigger power consumption produces, and has bigger current fluctuation therewith to D.C mutual-inductor 12, and D.C mutual-inductor 12 is small and weak Current signal change into voltage signal and feed back to single-chip microcomputer 13, single-chip microcomputer 13 judges after receiving signal that blower fan is Through work, then send operating instruction and drive air door to motor 2, motor 2 by the positioning rotating shaft 7 of air door page plate 6 Page plate 6 rotates.When air door page plate 6 rotates to maximum angle (during more than an angle of 90 degrees), and positioning rotating shaft 7 is snapped Blocking, motor 2 produces stall, and when locked rotor current is more than setting, meeting automatic decision motor 2 is by air door page plate 6 Opening and put in place, air door page plate 6 is fully opened discharge waste gas.When smoke exhaust ventilator quits work, D.C mutual-inductor 12 detect that electric current diminishes, and the voltage feeding back to single-chip microcomputer 13 diminishes the most therewith, and single-chip microcomputer 13 judges smoke exhaust ventilator Having quit work, sent a signal to motor 2 and close air door page plate 6, now air door page plate 6 is closed, Prevent exhaust gas recirculation.
