Description
Technical Field
The invention relates to the technical field of liquid diversion, in particular to a micro-liquid quantitative equivalent diversion system.
Background
There are many types of micro-fluid diverting systems, including pipeline diverting, microfluidic diverting, valve diverting, etc. Pipeline splitting is the most common method of splitting a fluid to different outlets by connecting multiple pipelines, however, pipeline splitting has some drawbacks. First, plumbing systems typically require a large number of plumbing and connectors, increasing the complexity and maintenance costs of the system. Second, there is a problem of fluid pressure loss due to the limited diameter of the pipe, resulting in a decrease in accuracy of the split flow. In addition, the pipe split is difficult to achieve high-precision equal split when dealing with a trace amount of liquid, because the trace amount of liquid is susceptible to the attachment and contamination of the inner surface of the pipe.
Microfluidic diversion is a method for achieving liquid diversion by using a microfluidic technology. The flow and distribution of liquid are controlled by micro devices such as micro channels, micro valves, micro pumps and the like. Although microfluidic shunt systems solve the problem of pipe-diversion to some extent, they are costly to manufacture and operate and have limited applicability for some specific experimental requirements, such as high pressure, high temperature or specific liquid properties.
Valve diversion is a method of controlling the flow of liquid using a valve. By opening or closing different valves, the liquid can be split to different outlets. However, there are some drawbacks to valve diversion. First, valve diversion systems typically require a large number of valves and controls, making the system complex and expensive. Secondly, the valve is opened and closed for a long time, the flow dividing speed is limited to a certain extent, and the valve is not suitable for the application requiring rapid flow dividing. In addition, the valve split is difficult to realize high-precision equal split when treating trace liquid, and the problem of split deviation exists.
In summary, the existing micro-liquid diversion system has the disadvantages of complexity, precision, applicability, cost and the like. Therefore, a new micro-liquid equivalent diversion device is needed to overcome these problems and improve the accuracy, efficiency and reliability of diversion.
