Abstract
The utility model relates to a shell casting piece of a flow meter, in particular to a shell casting piece of the flow meter. The shell casting piece comprises a straight pipe, wherein two ends of the straight pipe are both provided with radial convex plates; and the shell casting piece is characterized in that the middle part of the straight pipe is reserved with a radial hole for installing an inductor, wherein one side at the middle part of the straight pipe is processed with a radial bulge, and the radial hole is cast on the radial bulge. The shell casting piece of the flow meter, disclosed by the utility model, has better quality.
Description
Technical field
The utility model relates to a kind of metal casting.Specifically, be the shell cast member of flowmeter.
Background technology
All know at casting industry and flowmeter production industry, traditional flowmeter shell foundry goods comprises straight tube, and all there is radially boss at the straight tube two ends, and the centre of straight tube is cast with radial protrusion.After casting finishes, process the inductor installing hole by Vehicle Processing at described radial protrusion, to be used for installing the inductor of flowmeter.Owing on foundry goods, casting first radial protrusion, at radial protrusion processing inductor installing hole, so that the straight pipe wall at radial protrusion place is thicker, being prone to shrinkage defect again.In case shrinkage defect occurs, the installing hole of processing is prone to drainage after inductor is installed.Therefore, traditional flowmeter shell casting quality is relatively poor.
The utility model content
Problem to be solved in the utility model provides a kind of flowmeter shell foundry goods.This flowmeter shell foundry goods, quality is better.
For addressing the above problem, take following technical scheme:
Flowmeter shell foundry goods of the present utility model comprises straight tube, and all there is radially boss at the straight tube two ends, is characterized in being reserved with for the radial hole that inductor is installed in the middle of the described straight tube.
The further improvement of the utility model scheme is, a side has radial protrusion in the middle of the straight tube, and described radial hole is cast on the radial protrusion.
Take such scheme, have the following advantages:
Can be found out by such scheme, owing to when casting, being reserved with for the installing hole that the flowmeter inductor is installed in the centre of described straight tube, foundry goods is being machined in the process, do not needing preformed hole is machined, like this, can avoid the generation of shrinkage defect, thereby improve product quality.
Description of drawings
Fig. 1 is flowmeter shell casting structure schematic diagram of the present utility model;
Fig. 2 is that A-A is rotated counterclockwise 90 structural representations of spending among Fig. 1 after analysing and observe.
The specific embodiment
As depicted in figs. 1 and 2, flowmeter shell foundry goods of the present utility model comprises straight tube 3, the two ends circumference of straight tube 3 all is cast with radially boss 1, centre one side of described straight tube 3 is cast with radial protrusion 2, when casting, be reserved with on the radial protrusion 2 for the radial hole 4 that the flowmeter inductor is installed, described radial hole 4 communicates with the inner chamber of described straight tube 3.Compare with the flowmeter shell foundry goods in the background technology, not only need not process after the casting for the inductor installing hole that flowmeter is installed, improve working (machining) efficiency, and can avoid the generation of shrinkage defect, so that product quality improves greatly.
Claims (2)
1. the flowmeter shell foundry goods comprises straight tube (3), and all there is radially boss (1) at straight tube (3) two ends, it is characterized in that being reserved with for the radial hole (4) that inductor is installed in the middle of the described straight tube (3).
2. flowmeter shell foundry goods according to claim 1 is characterized in that the middle side of straight tube (3) has radial protrusion (2), and described radial hole (4) is cast on the radial protrusion (2).
