Description

Technical Field

[0001] The present application relates to the field of flowmeter castings, and in particular to a novel precision casting housing. Background Art

[0002] A flow meter is an instrument that indicates the measured flow rate and / or the total amount of fluid in a selected time interval. Simply put, it is an instrument used to measure the flow rate of fluid in a pipeline or open channel.

[0003] Patent document No. CN215064722U discloses a novel precision casting housing comprising a first flange straight tube, a second flange straight tube, a mounting tube, a protrusion, and a mounting hole. A mounting post is inserted into the mounting hole and can slide freely up and down. A mounting plate is provided at the end of the mounting post that protrudes from the protrusion. A through-hole is coaxially formed on the mounting plate and extends through the mounting plate. The mounting post is cushioned by a buffer unit to cushion its up and down movement. By separately disposing the first flange straight tube, the second flange straight tube, and the mounting tube, and by removably connecting the mounting tube to the first and second flange straight tubes, the first, second flange straight tubes, and the mounting tubes can be replaced if defects occur during manufacturing and assembly. This allows for universal interchangeability, particularly when wear occurs during long-term operation. This reduces costs, shortens the length of the casting mold, and reduces deformation during processing. While the aforementioned patent document allows for universal interchangeability, reducing costs, shortens the length of the casting mold, and reduces deformation during processing, the use of mounting posts to install the first and second flange straight tubes is cumbersome.
