Problems solved by technology

However, most of the existing proportional valves cannot be used in places with high pressure. The maximum air pressure of ordinary proportional valves can only reach 0.9Mpa, which cannot meet the needs of the market. Moreover, the existing proportional valves have small ranges, small flow rates, and low pressure. Low

Abstract

The invention discloses a high-voltage electric proportional valve. The high-voltage electric proportional valve comprises a housing assembly, an electromagnetic valve, a first piston rod, an air pressure sensor, a second piston rod, a button, a circuit board assembly, a display screen and a fiber-rubber diaphragm, wherein an input opening is formed in the rear end of the housing assembly, and anoutput opening is formed in the front end of the housing assembly; the button is connected with the circuit board assembly; the circuit board assembly is controlled by a single-chip microcomputer; theair pressure sensor is connected with the circuit board assembly; the electromagnetic valve is connected with the circuit board assembly; the first piston rod is arranged on the housing assembly; thefiber-rubber diaphragm is arranged in the housing assembly; the second piston rod is connected with the fiber-rubber diaphragm; and the display screen is arranged on the housing assembly. The high-voltage electric proportional valve disclosed by the invention is simple in structure, the control accuracy of the high-voltage electric proportional valve can achieve 10kPa level, the control precisionand the number displaying precision are high, and the high-voltage electric proportional valve is low in power consumption, long in service life, compact in volume and stable in temperature coefficient; and besides, a user can accurately master and control the magnitude of output air pressure, and can know the corresponding number displaying value.

Description

technical field [0001] The present invention relates to the technical field of electric proportional valves, and more specifically relates to a high-voltage 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, most of the existing proportional valves cannot be used in places with high pressure. The maximum air pressure of ordinary proportional valves can only reach 0.9Mpa, which cannot meet the needs of the market. Moreover, the existing proportional valves have small ranges, small flow rates, and low pressure. Low. Contents of the invention [0003] The purpose of the pres...
