Reed type self-adaptive flow-constant device

Abstract

The invention relates to a reed type self-adaptive flow-constant device which is characterized by comprising a shell with an inner cavity reducer, and an elastic check ring, an adjusting ring, a combined reed assembly and a circular arc tapered stress flow plate sequentially arranged on the inner cavity reducer of a middle section of the shell. The combined reed assembly is formed by concentrically overlaying and riveting two groups of reeds; the inner cavity reducer is a tapered hole formed in the middle section of the shell; the diameter of the big end of the tapered hole is matched with the sizes of the combined reed assembly and the circular arc tapered stress flow plate; the stress flow plate is matched with the combined reed assembly so as to form a gap channel for a fluid; one side, on which the elastic check ring is arranged, of the shell is a fluid entry end; and screw-thread sections are arranged on two sides of the inner cavity reducer of the shell and are used for connecting with a fluid conveying pipeline. The reed type self-adaptive flow-constant device provided by the invention is simple in structure, does not need manual intervention, and can self-adaptively realize stable control of the flow.

Description

technical field [0001] The present invention relates to a constant flow device for fluid delivery, in particular discloses a reed-type self-adaptive flow constanter, which is used in places with constant flow requirements, especially in seawater desalination systems, and realizes self-adaption Maintain flow stability. Background technique [0002] In industrial production and manufacturing, there is a wide demand for constant fluid flow. For example, the water production of seawater desalination equipment such as plate water generators requires a relatively stable value. In the desalination process, the overall cooperation of various components is required. Stability means that it is difficult to achieve the rated production capacity of the equipment, or even fail to reach the rated production capacity of the equipment, which inevitably requires the water replenishment of raw seawater to be constant. [0003] At present, the common practice is to install a manual shut-off v...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the defects of the prior art, and to design a reed-type self-adaptive flow constant, which can adaptively maintain a stable flow during the fluid delivery process without manual intervention, and solves the problem of untimely manual adjustment of the valve. The problem of inaccurate flow rate can also save the high cost of the existing technology that needs to be equipped with an automatic flow rate setting control system
