SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
An object of the utility model is to provide a piston stainless steel water gauge shell, through redesign fastening ring structure, simple structure, easily installation can effectively avoid the problem that the fastening ring was pulled apart easily in the assembling process or reduction manufacturing cost. In order to achieve the above purpose, the utility model adopts the following technical scheme:
(II) technical scheme
The utility model provides a piston stainless steel water meter shell, includes into water casing and play water casing, it screws to detain and seals plumbous hole cover to go out to be equipped with on the water casing, be equipped with into water the cavity mouth on the casing of intaking, be equipped with the tighrening ring on the cavity mouth of intaking, be equipped with a plurality of spanner draw-in grooves on the tighrening ring, the spanner draw-in groove can be the hole or the groove of round hole, square groove and other shapes.
Furthermore, the fastening ring can be fixed on the water inlet cavity opening through welding modes such as laser welding, argon arc welding, brazing welding or furnace welding.
Further, the fastening ring and the water inlet shell are integrally formed.
Furthermore, each component of the water meter shell is formed by adopting a stainless steel sheet or a pipe through stamping, stretching, expanding and pressing and the like.
(III) advantageous effects
Compared with the prior art, the utility model have obvious advantage and beneficial effect, particularly, through redesign fastening ring structure on intake cavity mouth, not only strengthen intake cavity mouth's compressive strength, avoided the easy problem of breaking of fastening ring or reduction manufacturing cost in the assembling process simultaneously, but also can cooperate and seal lead hole cover and play and seal lead hole effect.

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, most of the existing piston-type water meter cases are designed with a fastening ring (also called a ring buckle) 12 below a water inlet cavity port 11 on a water inlet case 1, the fastening ring 12 is composed of a plurality of convex blocks, which are convenient to fit with a screwing buckle 21 to assemble the water inlet case 1 and a water outlet case 2 together by a wrench, and through holes are designed on the convex blocks to facilitate later-stage fit with a lead sealing hole sleeve 22 to play a role in sealing a lead hole, the case is usually made of pig iron or copper, the fastening ring 12 and the water inlet case 1 are integrally formed, and the case is made of stainless steel, and the fastening ring 12 is usually welded below the water inlet cavity port 11 on the water inlet case 1, because the welding area of a single convex block is small, the case is easy to break at a welding point due to large stress.
Referring to fig. 2 to 5, a piston type stainless steel water meter case includes a water inlet case 1 and a water outlet case 2, the water outlet case 2 is provided with a screwing buckle 21 and a lead sealing hole sleeve 22, the water inlet case 1 is provided with a water inlet cavity opening 11, the water inlet cavity opening 11 is provided with a fastening ring 12, the fastening ring 12 is provided with a plurality of wrench slots 121, the wrench slots 121 may be circular holes, square grooves or other shaped holes or grooves, and only a wrench is convenient to clamp the fastening ring 12 to clamp the water inlet case 1.
Referring to fig. 3, the fastening ring 12 may be installed on the top of the inlet cavity, and some of the fastening ring 12 may exceed the top of the inlet cavity, and some of the wrench engaging grooves 121 may exceed the top of the inlet cavity, so as to facilitate the later stage of the assembly of the lead sealing hole sleeve 22 to perform the function of sealing the lead hole.
Referring to fig. 4, the fastening ring 12 may be installed at the bottom of the inlet of the water inlet cavity, and some of the fastening ring 12 may exceed the bottom of the inlet of the water inlet cavity, and some of the wrench engaging grooves 121 may exceed the bottom of the inlet of the water inlet cavity, so as to be convenient for the lead sealing hole sleeve 22 to play a role in sealing the lead hole at a later stage.
For the convenience of manufacture, the fastening ring 12 is designed as a single annular component, and the fastening ring 12 can be fixed on the water inlet cavity opening 11 by welding modes such as laser welding, argon arc welding, brazing welding or furnace welding.
In order to reduce post-manufacturing processes, the fastening ring 12 is integrally formed with the inlet housing 1.
In order to reduce the pollution of the water meter shell to water, all components of the water meter shell are formed by stamping, stretching or bulging and the like by adopting a stainless steel thin plate or a pipe.
The utility model discloses a redesign fastening ring structure on intake cavity mouth not only strengthens intake cavity mouth's compressive strength, has avoided the easy problem of wrenching off of fastening ring or reduction manufacturing cost in the assembling process simultaneously, but also can cooperate and seal the lead hole cover and play and seal the lead hole effect.
