Abstract
The application discloses a combined tube core, an ultrasonic water meter and a tube core manufacturing process, which comprises an upper core body, a middle reflection support and a lower core body, and the upper and lower core bodies are connected into one body and form a measuring channel inside; the middle reflection support comprises a ring-shaped closed sheet in a long strip structure, the middle section of the ring-shaped closed sheet is clamped and defined between the upper core body and the lower core body, the front end and the rear end of the hollow area of the ring-shaped closed sheet are respectively provided with a first reflection sheet and a second reflection sheet, the length dimension of the middle reflection support is greater than the length dimension of the upper core body and the lower core body, the first reflection sheet and the second reflection sheet are both arranged at the outer end of the measuring channel, and the first reflection sheet and the second reflection sheet are both symmetrically arranged relative to the tube core in an axial direction; and the tube core top is provided with a positioning hole. The beneficial effect is that the reflection sheet is installed on the tube core, and then the tube core is installed in the measuring pipeline of the ultrasonic water meter, so that the installation difficulty of the reflection sheet is simplified, and the installation precision of the reflection sheet is ensured.
