Embodiment Construction
[0021] The specific embodiment of the present invention, as shown in the accompanying drawings, is composed of a valve body 1, a valve plate 2 and an electric actuator 4. The valve body 1 is equipped with a valve plate 2, and the valve plate 2 is connected with the electric actuator 4; It is characterized in that the edge of the valve plate 2 is equipped with a heat-resistant annular flexible material 5 through two upper and lower annular steel plate splints 6; the electric actuator 4 is installed on the valve body 1 through the motor bracket 3.
[0022] The ring-shaped flexible material 5 is a 304 stainless steel sheet with a thickness of 0.1 mm, on which a number of openings are processed, so that the valve plate 2 can rotate in one direction without hindrance in the valve body 1 .
[0023] The electric actuator 4 is composed of a motor and a limit switch; the limit switch is provided with six travel switches, which can realize six-point limit to meet the position requirement...

The invention discloses a smoke discharge electric air valve and relates to air valve equipment for smoke discharge of a boiler. The smoke discharge electric air valve consists of a valve body, a valve plate and an electric actuating mechanism; the valve plate is arranged inside the valve body; and the valve plate is connected with the electric actuating mechanism. The smoke discharge electric air valve is characterized in that the edge of the valve plate is provided with a ring-shaped flexible material with heat resistance by both upper and lower ring-shaped steel sheet clamping plates; and the electric actuating mechanism is arranged on the valve body by a motor bracket. The ring-shaped flexible material is provided with a plurality of notches, so that the unblocked unidirectional rotation of the valve plate in the valve body is implemented. The electric actuating mechanism consists of a motor and a limiting switch; and the limiting switch is provided with six travel switches in total, which are arranged on the valve body, so that the six-point limiting can be implemented to meet the position requirement of the valve plate. The smoke discharge electric air valve has the characteristics of novel structure, simplicity and convenience for processing, convenience for use, low cost, safety, reliability and the like, and thus, the smoke discharge electric air valve belongs to a novel smoke discharge electric air valve integrating the economy with the practicality.
Description
technical field [0001] The smoke exhaust electric damper of the present invention relates to a wind generator for boiler smoke exhaust. Background technique [0002] At present, the smoke exhaust dampers used in boilers basically use motors to drive the valve plate to rotate, but this kind of dampers have great safety hazards: because the valve bodies of existing dampers are all made of steel pipes or webs, compared with Thin, the roundness cannot be guaranteed, and the out-of-roundness is increased through the transportation and installation process; the valve plate in the air valve is basically made of circular steel plate and other materials, so that due to the deformation of the valve body, the valve plate is in the valve The body cannot rotate smoothly, or even get stuck in a certain position of the valve body, which will easily burn the motor, affect the work of the air valve, and cause immeasurable losses such as boiler damage. In view of the problems existing in the...
