Binary fluid matching and mixing device

Abstract

The invention provides a binary fluid matching and mixing device. The binary fluid matching and mixing device comprises a valve body, a temperature adjusting device, a mixing device, a pressure adjusting device and a flow adjusting device, wherein the valve body comprises an upper cavity and a lower cavity; the temperature adjusting device is mounted in the upper cavity; the mixing device is positioned inside the lower cavity of the valve body; the pressure adjusting device is mounted between two ends of the mixing device and the lower cavity; the flow adjusting device is used for controlling the gas flow on one side, so as to control the volume ratio of binary gas. The binary fluid matching and mixing device can realize temperature compensation and mixing of fluid, and the ratio and flow are continuously adjusted. The structure is compact, a plurality of flow meters and proportional valves or flow controllers are canceled, the quantity of components is reduced, the structure of a fluid air distribution system is simplified, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of fluid machinery, and relates to a binary fluid proportioning and mixing device. Background technique [0002] With the development of science and technology, in many industries, it is necessary to mix two different fluids in proportion. For example, in welding, surface treatment, medical and electronic equipment manufacturing industries, it is often necessary to mix a variety of different gases A certain proportion of uniform mixing is put into use to obtain better results. Among them, the mixing of binary fluids is the most widely used. [0003] For example, the invention patent with the patent number of CN200610075329.X provides a fluid mixing device. An inner cylinder with a flow path diameter smaller than the inner diameter of the flow path is arranged inside the cylindrical flow path where the fluid flows. There is a fixed rotary blade composed of four radial blades, and the outer periphery of the ...

AI Technical Summary

Problems solved by technology

The advantage of the automatic adjustment ratio system is that it can realize pressure and temperature compensation, and the mixing ratio is accurate. The disadvantage is that there are many parts and the cost is expensive.

Manually adjust the proportioning system, generally, the input fluid passes through the pressure reducing and stabilizing valve, reaches the adjusting proportional valve, enters the mixer and outputs after manually adjusting the mixing ratio; its advantage is that the cost is low, but it cannot be compensated for temperature and pressure, and the proportion Separate from mixing process, larger volume
