The utility model is realized in this way:
A kind of two halves formula assembly water meter case, including left chamber body, right chamber body and water-stop sheet, the left chamber body and the right chamber
Body is mutually matched, and includes integrally formed middle casing, water inlet end and water outlet；In the left chamber body and the right chamber body
Wall is equipped with water-stop sheet positioning groove, when the left chamber body, the right chamber body, water-stop sheet assembling, by the water-stop sheet
Edge be all fastened in the water-stop sheet positioning groove, be sealingly mounted at the water-stop sheet in shell；The water-stop sheet
Entire water meter case is divided into upper and lower chambers, water flow is made to enter the upward chamber of lower chambers by the water inlet end, then via
The water outlet outflow.
Further, the connecting portion and the left chamber body of the water-stop sheet positioning groove and the water-stop sheet and institute
The connecting portion for stating right chamber body is equipped with cored solder, then combines each component by Welding, seals.
Further, the water-stop sheet is in horizontal positioned in shell, and middle part is hollow and annular, and both ends are in opposite curved
Folding.
Further, the water-stop sheet is equipped with water meter measurement device in hollow position, thus to from lower chambers to upper chamber
Flowing water is measured.
Further, independent punching press (the swelling pressure, extruding) molding of the left chamber body, the right chamber body and the water-stop sheet.
Further, each component of the water meter case is all made of stainless sheet steel or copper plate stamping (swelling pressure, extruding)
Molding.
Further, distinguish at the water inlet end port after assembled formation, water outlet port and middle casing upper end port
Equipped with screw thread column cap.
Further, the water meter case includes valve control water meter shell, rotor water gauge shell.
The utility model has the advantages that
It is equipped with water-stop sheet positioning groove in the left and right cavity of the utility model, when assembling is aided with cored solder welding procedure solution
The problem of housing unit of having determined positioning and sealing, and shell is divided into two chambers up and down, to force water flow can only be by water meter machine
Core is flowed from cavity of resorption to epicoele, carries out accurate measurement.Water-stop sheet acts as supporting role in shell simultaneously, and enhancing shell type chamber is strong
Degree, prevents shell deformation tension or in compression.
The shell product any surface finish of the utility model such as mirror surface, novel appearance light.

Specific embodiment
Embodiment 1
By taking valve control water meter shell as an example, as Figure 1-Figure 5, a kind of two halves formula assembly water meter case, including left chamber body 1,
Right chamber body 2 and water-stop sheet 3, the left chamber body 1 and the right chamber body 2 are mutually matched, and include integrally formed middle casing
11, water inlet end 12 and water outlet 13；The left chamber body 1 and 2 inner wall of right chamber body are equipped with the water-stop sheet positioning being mutually matched
Groove 14 all blocks at the edge of the water-stop sheet 3 when the left chamber body 1, the right chamber body 2, the water-stop sheet 3 assemble
It closes in the water-stop sheet positioning groove 14, is sealingly mounted at the water-stop sheet 3 in shell；The water-stop sheet 3 is by entire water
Watch shell is divided into upper and lower chambers, makes water flow that can only enter the upward chamber of lower chambers by the water inlet end 12, then via institute
State the outflow of water outlet 13.
In order to solve the sealing problem of component, in the connecting portion of the water-stop sheet positioning groove 14 and the water-stop sheet 3,
And the connecting portion of the left chamber body 1 and the right chamber body 2 is equipped with cored solder 4, then by Welding by each component
Sealing.
In order to flow water flow from cavity of resorption to epicoele, the water-stop sheet 3 is in horizontal positioned in shell, and middle part is hollow
