Hydraulic-control micro-valve gas supply reversing device based on magnetic drive and use method thereof

Abstract

The invention relates to a hydraulic-control micro-valve gas supply reversing device based on magnetic drive and a use method of the hydraulic-control micro-valve gas supply reversing device based on magnetic drive and belongs to the technical field of precise measuring devices. According to the hydraulic-control micro-valve gas supply reversing device based on magnetic drive, the bottom of a valve body is provided with a gas inlet, the top of the valve body is symmetrically provided with a gas outlet I and a gas outlet II, the gas inlet communicates with the gas outlet I and the gas outlet II through a micro-channel, a magnetic liquid drop is located in the micro-channel, the width of the magnetic liquid drop is larger than that of the gas inlet, the gas outlet I and the gas outlet II, the depth and the width of the magnetic liquid drop are equal to the depth and the width of the micro-channel correspondingly, the magnetic liquid drop can move in the micro-channel, so that the gas outlet I or the gas outlet II is blocked, when the magnetic liquid drop blocks the gas outlet I or the gas outlet II, the magnetic liquid drop does not block the gas inlet, and an electromagnetic coil I and the electromagnetic coil II are arranged on the two sides of the valve body correspondingly. By the adoption of the hydraulic-control micro-valve gas supply reversing device based on magnetic drive and the use method of the hydraulic-control micro-valve gas supply reversing device based on magnetic drive, the electromagnetic coils are controlled to generate a magnetic field so that the magnetic liquid drop can be controlled to move, and therefore the micro-valve reversing function is achieved; non-contact type drive can be achieved, the reliability is high, and implementation is easy.

[0002] The multi-way reversing valve is one of the key components in the construction machinery system. With the wide application of micro valves in various fields, the requirements for the reversing valve are getting higher and higher. At present, the main driving methods are mainly pressure-driven reversing and The photosensitive droplet drives the reversing. The main operation is to control the switch of the microvalve by controlling the pressure and the intensity of the light. Its control precision is low, the dynamic response is poor, the cost is high, and the number of times of use will cause certain damage to the valve body. thereby reducing flow efficiency

Disadvantages of photosensitive reversing valve: 1. It is greatly affected by temperature; 2. The response speed is slow, between ms and s, and the delay time is affected by the illuminance of incident light; 3. It is a consumable, usually used in street lighting, alarms, Stair lights and night lights are not suitable for the field of micro-channels, because the light intensity is not properly controlled, and the moving distance of the photosensitive liquid droplets is different, and the accuracy is difficult to meet the requirements
