AI Technical Summary
Technical Problem
Existing laminar flow components are prone to accumulation of impurities and have low processing efficiency, which affects measurement accuracy and cleanliness.
Method used
A laminar flow assembly is designed. By providing a first channel on the main body and an inner core in the first channel, the inner core is interfered with the inner wall of the first channel and separated into a plurality of channels with smaller cross-sectional area to form a stable laminar flow state, while simplifying the structure and reducing processing difficulty.
Benefits of technology
It effectively reduces the accumulation of impurities in laminar flow components, improves processing efficiency, and enhances measurement accuracy and the cleanliness of mass flowmeters.

Abstract
The present application is applicable to the technical field of metering equipment, and proposes a laminar flow component and a mass flow meter, wherein the laminar flow component comprises: a main body, a first channel is provided on the main body, and the first channel is used for fluid circulation; an inner core is accommodated in the first channel and has an interference fit with the inner wall of the first channel, a second channel is provided on the inner core, and the second channel is used for fluid circulation, and the fluid flow direction of the second channel is the same as the fluid flow direction of the first channel; in the laminar flow component provided by the embodiment of the present application, the inner core and the base can be cleaned separately before assembly, which can reduce impurities hidden inside the inner core and the base; the inner core is made to have an interference fit with the inner wall of the first channel to reduce impurities that may be generated at the connection portion between the inner core and the base, thereby alleviating the problem of easy accumulation of impurities in the laminar flow component; at the same time, the inner core is made to have an interference fit with the inner wall of the first channel, which can also reduce the difficulty of processing and improve the processing efficiency.
