Detailed Description

The following describes in further detail embodiments of the present invention with reference to the accompanying drawings. The following embodiments are provided to illustrate the present invention, but not to limit the scope of the present invention.

As shown in figure 1, the explosion-proof electric fan-shaped glasses valve comprises a triangular main valve body 1 consisting of a panel and a back plate, two fan-shaped valve plates 3 provided with guide plates 2, a shaft hole 4 at the top of the main valve body 1 and a driving device 15. The guide plate 2 of the valve plate 3 is provided with guide teeth 11, and the work is stable due to the chain wheel drive. A valve plate shaft 20 is erected in the shaft hole 4. The cylindrical portion 5 of the valve plate shaft 20 passes through the shaft hole 4. A gear 12 is arranged at the right angle of the bottom of the main valve body 1; the gear 12 is mounted in a right-angled rotary hole 19 in the bottom of the main valve body 1 via rotary shafts 18 on both sides of the gear. A rotating shaft 18 on one side of the gear 12 penetrates through a rotating hole 19 to be connected with the chain wheel I13. The driving device 15 is arranged on the left side of the bottom of the main valve body 1. The drive means 15 is of prior art.
