Embodiment
Fig. 1 ~ 5 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 5 pair of the utility model:
With reference to accompanying drawing 1-2, this flue Flap valve, comprises housing 6, three groups of panel turnover devices are side by side installed in housing 6, middle one group of panel turnover device end connects electric actuator 5, and panel turnover device end, both sides connects actuator 9, and electric actuator 5 drives both sides actuator 9 to rotate simultaneously.Electric actuator 5 drives the driving mode of both sides actuator 9 to be link transmission mode.
With reference to accompanying drawing 3-4, accompanying drawing 3 and accompanying drawing 4 are the structural member figure after removing electric actuator 5 and actuator 9.Panel turnover device comprises turnover panel 2 and turnover panel rotatingshaft, and turnover panel rotatingshaft is welded by center sleeve 4, non-executing device side minor axis 1 and final controlling element side minor axis 3.Turnover panel 2 and center sleeve 4 all select corrosion resistant stainless steel to be made.Non-executing device side minor axis 1 and final controlling element side minor axis 3 support respectively by bearing unit 8 and are arranged on the shell wall of housing 6 left and right sides, and turnover panel 2 centrally sleeve pipe 4 axial direction is arranged on outside center sleeve 4.Turnover panel 2 outer surface installs sealing offset plate 7, and both are linked together through turnover panel 2 and sealing offset plate 7 by connecting bolt by all perforates on turnover panel 2 and sealing offset plate 7.
With reference to accompanying drawing 5, bearing unit 8 comprises bearing housing 801, bearing cap 802 and bearing 803, bearing housing 801 is arranged on the sidewall of housing 6, bearing 803 is arranged in bearing housing 801, bearing cap 802 is arranged on bearing housing 801 outer end, the axle head of non-executing device side minor axis 1 and final controlling element side minor axis 3 all stretches in the bearing 803 of respective side, installs dust ring 804 between the axle head of bearing 803 and bearing housing 801 in space.Bearing cap 802 offers oil filling mouth 805.
