Abstract
The present invention discloses a water meter case including a case body (1) and the flange positioned on the case body (1). The water meter case is characterized in that said case body (1) is a barrel-shaped body that is weld with steel board and weld lines (4) are formed on the surface of the case body. Said flange includes a meter head flange (3) that is fixed in the center of the surface of the weld case and a port flange (2) that is weld on the port of said case body (1); the present invention also discloses a manufacturing method of the water meter case. Comparing to the prior art, the production of the water meter case in the present invention has the merits of simple machining and low cost, and is especially suitable for the outsize water meter that has a diameter bigger than 400mm.
Description
Technical field
The present invention relates to a kind of water meter parts, relate in particular to a kind of water meter shell, the invention still further relates to the manufacture method of this water meter shell, belong to flow counting equipment technical field in the physical department.
Background technology
Water meter is a kind of common flow counting equipment, can on tap water pipeline, see widely, present domestic traditional water watchcase generally adopts casting pig to be processed into the blank watchcase, carries out finishing again, adopts large-scale stock-removing machine processing, and at more than the diameter 400mm especially big water meter shell the time, still follow above classic method, have following deficiency like this: one, technology is loaded down with trivial details, working environment is seriously polluted again, and the workman processes labour intensity and beats; Secondly, the disposable infusion of financial resources of equipment is huge, the economic benefit of bringing simultaneously has not high; Moreover traditional water meter shell outward appearance is unalterable, seems more stiff.
The patent No. is that the Chinese invention patent of ZL00125206.2 discloses " water meter shell and manufacture method thereof " (publication number is CN1118686C), the blind nut body cooperatively interacts with outer blind nut body and is spirally connected into the water meter shell in the main employing of this invention extrusion modling, also wants the site, many places to carry out the enclosure-type welding after finishing.Aforesaid invention has had very big progress on traditional water meter job operation, but technology is still more loaded down with trivial details, and parts are various, and the processing that is spirally connected acquires a certain degree of difficulty, and brings the cost height, and throughput rate is low, in the time of at especially big water meter shell, still seems practical inadequately.
Summary of the invention
First technical matters to be solved by this invention provides a kind of simple in structure, easy to process, cheap water meter shell.
Second technical matters that the present invention solves provide a kind of processing technology simple, at above-mentioned water meter casing manufacturing method.
The present invention solves the technical scheme that above-mentioned first technical matters adopts: this water meter shell comprises housing and is positioned at flange on this housing, it is characterized in that described housing is the cylindrical body that steel plate is welded, its surface forms sealing wire, aforesaid flange comprises gauge outfit flange and terminal port flange, aforesaid gauge outfit flange is fixed in the aforementioned surface of shell of welding centre position, and aforesaid terminal port flange is fixedly welded on the port of aforementioned housing.
The present invention solves above-mentioned second technical scheme that technical matters adopted: a kind of water meter casing manufacturing method is characterized in that comprising the steps:
A, the steel plate that will cut out are rolled into tubular water meter shell housing, weld two opposite side, and surface of shell forms sealing wire;
B, a gauge outfit flange is fixed in welding in the middle of the sealing wire of above-mentioned surface of shell, fixes two terminal port flanges in the port welding of above-mentioned housing.
Further the present invention can also adopt following technical scheme:
Described gauge outfit flange is welded in the centre position of aforementioned sealing wire, further improves the firm welding of housing, also makes the whole stressed of housing more become even.
The described gauge outfit flange degree of lip-rounding is rectangle, rectangle or the circle that both sides are provided with symmetrical circular arc, and its side face is provided with several mounting holes, and this mounting hole is convenient to the water meter shell parts that other need are installed.
Described housing is a cylinder, and this barrel diameter is more than the 400mm.Practical especially at the water meter shell more than the diameter 400mm.
Described gauge outfit flange adopts casting processing flange, and described terminal port flange adopts standard flange or casting processing flange, further enhances productivity, and reduces labour intensity.
Described steel plate adopts the A3 steel plate.
Compared with prior art, the invention has the advantages that: traditional way be water meter shell housing one-body molded after following process again, the present invention adopts iron and steel sheet and plate is rolled into the back welding, water meter case and flange split recombinant are welded then, following process is simple, the water meter hull specification is applicable to from small to large, be particularly suitable for the large-diameter water meter shell of diameter 400mm, loaded down with trivial details technologies such as casting have been saved, make integral processing simple, easy to operate, fund input is limited, and the economic benefit of bringing simultaneously is considerable; Adopt general section bar and cast flange or standard flange, make that workman's working environment pollution is few, labour intensity is little, and throughput rate increases substantially; Watchcase quality of the present invention upper strata, overall appearance is good, lays a good foundation for putting on market.

Fig. 2 is the A-A cut-open view of Fig. 1
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
With reference to figure 1 and Fig. 2, a kind of water meter shell of present embodiment comprises housing 1, gauge outfit flange 3 and terminal port flange 2, housing 1 winds up the cylinder-like body that is welded for after the cutting of A3 steel plate, this cylinder-like body diameter is for more than the 400mm, housing 1 surface forms sealing wire 4, gauge outfit flange 3 is by in the middle of the sealing wire 4 that is fixedly welded on housing 1, terminal port flange 2 is by being fixedly welded on the port of housing 1, terminal port flange 2 can adopt standard flange or casting processing flange, gauge outfit flange 3 degree of lip-roundings are the rectangle that both sides are provided with symmetrical circular arc, and its side face is provided with several mounting holes 31, and this gauge outfit flange 3 can adopt casting processing flange
Its step of the manufacture method of aforementioned water meter shell is as follows:
(1) the A3 steel plate that will cut out is rolled into cylindric watchcase housing, welds two opposite side, and surface of shell forms sealing wire;
(2) the gauge outfit flange that a casting forms is fixed in welding in the middle of the sealing wire of above-mentioned surface of shell, fixes two terminal port flanges in above-mentioned housing port welding, just makes water meter shell of the present invention.
