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 4, a valve-controlled stainless steel water meter shell comprises a cavity 1, a cavity dividing plate 3, a water inlet pipe 4 and a water outlet pipe 5, wherein a chassis 2 is welded at the bottom of the cavity 1, the cavity dividing plate 3 is welded inside the cavity 1, the water inlet pipe 4 and the water outlet pipe 5 are respectively welded at two sides of the cavity 1, a valve rod sleeve 6 is welded on the water outlet pipe 5, a valve rod 7 is clamped in the valve rod sleeve 6, a valve ball 8 is connected below the valve rod 7, two clamping ring grooves 51 are arranged in the water outlet pipe 5, the two clamping ring grooves 51 are symmetrically arranged at two sides of the valve ball 8, a clamping ring 9 is clamped in the clamping ring groove 51, a sealing ring seat 13 is clamped between the clamping ring 9 and the valve ball 8, a sealing ring I11 and a sealing ring 12 are sequentially clamped at one end of the sealing ring seat 13, a connecting thread 52 is arranged on the outer wall of one end of the water outlet pipe 5, and a sealing joint 13 is clamped at the inner wall, wherein the sealing ring seat 10 and the sealing joint 13 are plastic pieces.
