Abstract

The invention relates to the field of vacuum equipment, in particular to an electric vacuum baffle valve and vacuum equipment with the same. The electric vacuum baffle valve comprises a valve body, a partition plate, a valve element assembly, an electromagnetic push block, an ejector pin, a stepping motor and a control circuit board. The stepping motor drags the valve element assembly to rotate to enable the baffle to move up and down, the baffle is provided with a second rubber ring, and when the second rubber ring moves downwards to abut against the second sealing surface of the valve body, a first flange connector and a second flange connector are separated, and the electric vacuum baffle valve is closed. When the second rubber ring is moved upwards to be separated from the second sealing surface of the valve body, the first flange connector communicates with the second flange connector, and the electric vacuum baffle valve is opened. According to the electric vacuum baffle valve, the stepping motor is used as a driving element, and the defects that in the prior art, noise is large, vibration is large, and the energy consumption and waste are large are effectively overcome.

Description

technical field [0001] The invention relates to the field of vacuum system pipeline control, in particular to an electric vacuum baffle valve and vacuum equipment with the same. Background technique [0002] The industry now uses electromagnetic vacuum flapper valves and pneumatic vacuum flapper valves to control the on-off of vacuum pipelines. The electromagnetic vacuum flapper valve uses the electromagnet adsorption module as the driving module. After the valve is opened, it consumes power to maintain the open state of the electromagnetic coil. Its disadvantage is that it produces huge sound and vibration when the magnet is absorbed, and its vibration will affect the performance of vacuum equipment, and its huge sound will reduce user experience and waste a lot of energy consumption. [0003] Pneumatic vacuum flapper valve must be equipped with an air compressor as the drive and connected with a long air pipeline, the maintenance of the air pipeline is complicated, and en...
