▎ 摘　　要

NOVELTY - The valve has electromagnetic pulse seat (1), base provided with back air chamber (7), and connecting seat provided with a front air chamber (8). Outer two sides of the connecting seat are provided with a first air inlet (9). Outer surface of piston (10) is connected with a sealing film. Inner side of the piston is provided with a limiting device. Two sides of the bottom of the back air chamber are provided with a second air inlet (13). Outer side of the bottom of flange is provided with a connecting disc (14) whose outer bottom side is provided with an air bag (15). A first exhaust port (19) is provided on armature outer two sides. The base bottom is provided with a vent pipe (20). Bottom inner side of the base is connected with a filter screen (21). A middle section of the inner side of the armature is provided with an electric control valve core that is provided with an air pressure sensor. Outer two sides of the fixing seat are provided with a second exhaust port. USE - Piston type electromagnetic pulse valve i.e. bag type dust remover pulse ash cleaning vibration airflow generating device. ADVANTAGE - By using the piston to control the air flow, the opening speed and the opening area of the air inlet is improved. In addition, the compressed air is filled in the air bag, which can improve the flow speed of the gas, which is good for improving the exhaust quantity of the device, so as to improve the cleaning effect and avoid the dust remover cannot be cleaned. The filter screen is made of graphene material, so that the filtering and absorbing effect of the filter screen can be improved. The electromagnetic pulse valve is used in the process of using, it is easy to cause the air pressure between the front and back air chambers is not balanced caused by various factors.
