3. through the design of casing bottom cushion chamber, place the buffer material layer in the cushion chamber, through the corresponding volume that has enlarged the table chamber of elastic compression of buffer material, digested the volume expansive force behind the water becomes ice to reduce and exempt from because of the volume expansion rush to the water gauge glass and the water gauge plastic component formation's high pressure, prevented glass and plastic component's fracture.

The utility model discloses the design of integral type casing, bearing capacity is strong, does not leak, the corrosion resistance, adopts stainless steel material to make, after the life is up, can retrieve this casing, after renovating processes such as cleaning, polishing, can come into operation once more, avoids unnecessary extravagant, reduce cost; in addition, the whole structure is simple, the volume is small, the manufacturing process is simple, the production cost is low, the service life is long, and the wide popularization and application are facilitated.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1-4, the stainless steel water meter case of the present invention comprises a case 1 made of stainless steel material and a cover 2 adapted to the case 1, the case 1 is of an integral structure, a watch core accommodating chamber 11 with an upward opening is formed inside the case 1, and the left side of the watch core accommodating chamber 11 is disposed at a water outlet 3 communicated with the watch core accommodating chamber 11 and the outer side of the case 1 is integrally formed with a water inlet 4 communicated with the watch core accommodating chamber 11. The utility model relates to an ingenious adopts stainless steel material to make the casing 1 of integral type structure, and bearing capacity is strong, the non-seepage, nonrust losing, is of value to health. The anti-disassembly cover 2 is arranged, so that the phenomenon that the water meter is disassembled without authorization can be effectively avoided, the loss of a water meter company and a user is prevented, and the normal water use of the user is ensured.

The anti-disassembly cover 2 is arranged on the top of the shell 1 and can seal the opening of the watch core accommodating cavity 11. The anti-disassembly cover 2 comprises a transparent or semitransparent rotating meter cover 21, a cover 22 and an anti-disassembly cover 23, wherein an internal thread 221 is formed at the bottom of the inner side wall of the cover 22, an external thread matched with the internal thread 221 is arranged at the top of the shell 1, a boss 222 for placing the rotating meter cover 21 is integrally formed at the top of the cover 22, the bottom of the rotating meter cover 21 protrudes outwards to form a flange 211, a concave position 231 matched with the flange 211 is integrally formed at the upper end of the anti-disassembly cover 23, a hook leg 232 capable of being hooked at the bottom of the cover 22 is arranged at the lower end of the anti-disassembly cover 23, and the rotating meter cover 21 is fixed on the boss 222 of the cover 22 through the anti-disassembly cover 23. The cross section of the water outlet 3 is circular, one end of the water outlet close to the shell 1 is larger, and the other end of the water outlet far away from the shell 1 is gradually reduced. The cross section of water inlet 4 is personally submitted circularly, and it is nearly the one end of casing 1 is great, and the other end of keeping away from this casing 1 is the form that dwindles gradually, and the cross section of delivery port 3 and water inlet 4 is circular, effectively increases the bore of delivery port 3 and water inlet 4, improves the circulation of water, ensures the water gauge and measures correctly, avoids unnecessary measurement dispute to avoid bringing unnecessary economic loss for the supplier and demand both sides.

The utility model discloses a stainless steel watchcase is a cushion chamber 5 at casing bottom downwardly extending, can fill up the buffer material (like silica gel class) that has waterproof nature in the cushion chamber. When water in the water meter is frozen: the elastic compression of the buffer material correspondingly enlarges the volume of the meter cavity, and the volume expansion force after the water turns into ice is digested, so that the high pressure formed by flushing the water meter glass and the water meter plastic component due to the volume expansion is avoided, and the glass and the plastic component are prevented from cracking. When the water is frozen in the surface, the pressure caused by the volume expansion of the ice in the surface is reduced, and the buffer material gradually restores to the original position under the high elastic recovery action of the buffer material.

When the utility model discloses a life is after full, can retrieve this casing 1 by water gauge company or other responsible departments, then after renovating processes such as cleaning, polishing, install new watch core after, can drop into operation once more, long service life avoids unnecessary extravagant, reduce cost.
