Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

The present invention will be further described with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 7, a flat-cut stainless steel water meter casing comprises a partition plate 1, an upper cavity 2 and a lower cavity 3, wherein the upper cavity 2 and the lower cavity 3 are matched with each other and are fixedly connected by welding to form a middle casing 4, a water inlet channel 5 and a water outlet channel 6, the partition plate 1 is welded in the middle casing 4, a vertical cylindrical sheet 11 matched with the inner wall of the middle casing 4 is arranged above one end of the partition plate 1 just like a large cylindrical sleeve small cylinder, so that the contact surfaces of the large cylindrical sheet and the small cylindrical sheet are easy to be matched, lap joint is relatively simple, brazing flux is convenient to fill, the vertical cylindrical sheet 11 and the partition plate 1 are in transition connection through taper and circular arc, water flow resistance and water pressure loss are reduced, when a water meter casing is processed, if lathing threads are directly processed at the outer side of a port of the middle casing 4, the end of the water inlet channel 5 and the end of, just treat the back that the welding of last cavity 2 and lower cavity 3 finishes, directly in the middle of the 4 mouthfuls of shells outside, inhalant canal 5 and exhalant canal 6 tip threading, if the direct processing threading of not being convenient for, the water gauge casing still includes water inlet facing 7, delivery port facing 8 and middle shell mouth facing 9, water inlet facing 7, delivery port facing 8 and middle shell mouth facing 9 weld respectively in inhalant canal 5 tip, exhalant canal 6 tip and the middle 4 mouthfuls of shells outside, weld simultaneously between inhalant canal 5 and middle shell 4 and seal lead block 10, the later stage of being convenient for prevents that the water gauge from being unpacked apart privately by the user.
