Description
Technical Field
The utility model relates to the technical field of water meters, in particular to a welded water meter shell and a water meter.
Background
At present, a support ring is generally arranged in a meter shell of the water meter, the support ring is used for installing a meter core and simultaneously plays a role of separating a waterway, the support ring is generally connected and fixed with the inner wall of a water inlet joint and the inner wall of a water outlet joint of the water meter, at present, a penetration welding mode is generally adopted to weld and fix the support ring with the inner walls of the water inlet joint and the water outlet joint respectively, even if an electric arc penetrates the meter shell of the water meter from the outside to form a small hole, a welding path is formed behind the small hole along with the movement of a heat source, so that the support ring positioned in the meter shell of the water meter is welded and fixed, however, the support ring after the welding and fixing is adopted in the mode has lower connection strength due to discontinuous welding path.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a welded water meter shell and a water meter, which enable the support ring to have higher connection strength after being welded and fixed.
In order to solve the technical problems, the welded water meter case provided by the utility model comprises a case body and a supporting ring, wherein the supporting ring is positioned in the case body;
the watchcase body comprises a water inlet connecting part and a water outlet connecting part, and a slotted hole is formed in the lower wall body of the water outlet connecting part;
the support ring comprises an annular part, a first connecting part and a second connecting part are arranged on the annular part, the first connecting part penetrates through the slotted hole and is welded with the outer wall of the water outlet connecting part, and the second connecting part is fixed on the water inlet connecting part.
Preferably, the slot hole is arc-shaped and extends around the axis of the water outlet connecting part, and the first connecting part of the first connecting part is arc-shaped and is matched with the slot hole.
Preferably, a connecting area extending horizontally is arranged on the upper wall body of the water inlet connecting part, and the second connecting surface of the second connecting part is attached to the inner wall of the connecting area and fixed through welding.
The water meter provided by the utility model comprises the welded water meter shell.
After adopting the structure, compared with the prior art, the utility model has the following advantages:
the water meter shell is provided with the slotted hole on the water outlet connecting part, so that when the supporting ring is installed, the first connecting part of the supporting ring can penetrate out of the slotted hole, then the supporting ring is welded and fixed on the outer wall of the water outlet connecting part in a conventional way, the welding bead is continuous, the strength of the supporting ring after welding is higher, and after the welding is finished, the first connecting part extending out of the slotted hole is ground.
