Title:
BERNOULLI'S PRINCIPLE-BASED ELECTROMECHANICAL TIME DELAY VALVE AND AIR COMPRESSOR EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2021/017857
Kind Code:
A1
Abstract:
Disclosed is an electromechanical time delay valve, comprising a valve seat body (1) and an electromagnetic valve (2). The electromagnetic valve comprises an actuating valve core (3) and a reset spring (4), and the actuating valve core can produce displacement motion or locking motionlessness under the action of the electromagnetic force of the electromagnetic valve and/or the elastic force of the reset spring. The valve seat body and/or the electromagnetic valve are provided with an input port (5) and at least one first output port (6), and the valve seat body and/or the electromagnetic valve are provided with a first channel (7). The valve seat body and/or the electromagnetic valve are further provided with at least one second output port (8), and are further additionally provided with an isolation diaphragm (9) facing the second output port. According to the time delay valve, the Bernoulli's principle is applied to the electromagnetic valve structure to make the opening and closing behaviors of the electromagnetic valve more scientific and reasonable; the layout form of multiple output ports reduces the volume of the electromagnetic valve and enables same to have a quick response function; the use of a delay turn-on circuit enables the electromagnetic valve to have reliable delay actuation properties. Also disclosed is an air compressor equipped with the Bernoulli's principle-based electromechanical time delay valve.
