Abstract

The invention discloses a multi-point input-presetting electric proportional valve. The valve comprises a shell assembly, a circuit board assembly, a button, a display screen, an electromagnetic valve, a bus plate, a fiber-rubber diaphragm, a piston rod, a piston, a four-pin connector rubber core, a five-pin connector rubber core and connecting wire heads; wherein the button is connected with thecircuit board assembly, the display screen is connected with the circuit board assembly, the electromagnetic valve is connected with the circuit board assembly, the bus plate is connected with the circuit board assembly, one end of the piston rod is connected with the fiber-rubber diaphragm, the other end of the piston is connected with the piston rod, and the connecting wire heads are arranged onthe corresponding four-pin connector rubber core and the corresponding five-pin connector rubber core in a sleeving mode. The valve is simple in structure, capable of greatly improving control and digital display precision, low in power consumption, long in service life, small in size and stable in temperature coefficient; and the using personnel can accurately master and control the output air pressure of 16 points, and can know the corresponding digital display value, so that stable transmission of signals is guaranteed.

Description

technical field [0001] The present invention relates to the technical field of proportional valves, and more specifically relates to a multi-point preset input electric proportional valve. Background technique [0002] Proportional valves are often used in industrial pneumatic equipment to adjust the output air pressure to facilitate the control of the stroke of the cylinder. For example, the proportional valve is widely used in industrial pneumatic equipment such as the pressure regulation system of various pneumatic systems, for use with cylinders, with pneumatic triples, with pressure vessels, etc. However, in the proportional valve application industry, some industries do not require continuous pressure control. Most of the existing proportional valves require analog control, with fewer control points. Generally, 4 points are preset, which is costly and complicated to control. Contents of the invention [0003] The purpose of the present invention is to overcome the a...
