Specific embodiment
Below to illustrate a specific embodiment of the invention shown in Fig. 1 to Fig. 8.
A kind of light and thin type water meter case, as shown in Figures 1 to 4, including table body 1, the water inlet pipe of 1 left and right sides of table body is set
2, outlet pipe 3, and the machine core locating ring 4 being arranged in table body 1, table body 1 include ontology 21 and are embedded in 21 upper port of ontology
In top ring 22, ontology 21, top ring 22, water inlet pipe 2, outlet pipe 3 be stamped to form by the steel pipe of respective diameters respectively, specifically
The steel pipe of carbon constructional quality steel can be used.21 lower end of ontology forms the constricted arc ring 6 around lower port 5, a left side for ontology 21
Right two sides open up water inlet 7, water outlet 8 respectively；21 lower port 5 of ontology welds small round plate 12 as shell through laser welding process
Body bottom；Port external screw thread 13 is arranged in 22 upper end of top ring；Stamped molding water inlet pipe 2, outlet pipe 3 outer end be provided with adapter tube
External screw thread 19, inner end form the cambered surface mouth 14 to match with 1 water inlet 7 of table body, 8 place outer surface of water outlet through laser cutting,
Water inlet 7, the 8 place outer surface of water outlet of table body 1 are soldered to through laser welding process respectively；Between top ring 22 and ontology 21
It is welded using laser welding process, machine core locating ring 4 is also welded in 21 inner cavity of ontology through laser welding process.
Since the water inlet position of machine core is lower and water exit position is higher, water flow flows through machine core metering (driving impeller from lower
Rotation) it is flowed out from eminence, as shown in Figure 5, Figure 6, the position of the water inlet 7 of table body 1 is lower and the position of water outlet 8 is higher.This
Water inlet 7, the water outlet 8 of invention table body 1 are in be made of semilunar, the half a month camber line of water inlet 7 with string 16 camber line 15
15 in lower and string 16 upper, the half a month camber line 15 of water outlet 8 in upper and string 16 under, water inlet 7,8 shape phase of water outlet
Together, equal in magnitude, upper and lower orientation is opposite.As shown in Figure 7, Figure 8, water inlet pipe 2, outlet pipe 3 are identical, and the two can be interchanged,
Its inner end is greater than outer end, and inner end inner cavity is greater than water inlet 7 or water outlet 8, and water inlet pipe 2 or 3 outer wall of outlet pipe and inner wall are through rushing
Swaging at the face of scabbling 17, make the inner end of water inlet pipe 2 or outlet pipe 3 also and be in match with water inlet 7, water outlet 8 by camber line 15 with
String 16 is constituted semilunar, the face of scabbling 17 of water inlet pipe 2 above and the face of scabbling 17 of outlet pipe 3 is below.Above in this way
Design, not only can satisfy disengaging water flow upper and lower position require, the loss of intake pressure can also be efficiently reduced, keep
Water inlet is steady, and flow of inlet water is stablized；It is also convenient for manufacturing simultaneously.
It is positioned for the ease of machine core locating ring 4 and top ring 22, as illustrated in fig. 2 or fig. 5,1 internal chamber wall of table body is provided with down
Positioning step 23 and upper positioning step 24, machine core locating ring 4 and top ring 22 are separately positioned on lower positioning step 23 and upper positioning
On step 24, and respectively welded through laser welding process and 21 internal chamber wall of ontology.
As shown in Figures 1 to 4, setting triangle reinforcing rib 18 between 1 outer wall of the face of scabbling 17 of water inlet pipe 2 and table body, and
Reinforcing rib 18 opens up aperture 20, sets lead sealing for adding, tampers in violation of rules and regulations to prevent other people；The setting of reinforcing rib 18, while can also reinforce
The firmness of the connection of water inlet pipe 2 and table body 1.1 internal chamber wall of table body gets rusty with water inlet pipe 2,3 inner wall of outlet pipe in order to prevent, table body
1, the surface of internal cavity spraying Teflon dope layer or painting nickel layer of water inlet pipe 2, outlet pipe 3, forms corrosion protection layer.Table body 1, water inlet
Pipe 2, outlet pipe 3 outer wall surface varnish with lacquer, with prevent from getting rusty with it is beautiful.
Since table body 1, water inlet pipe 2, outlet pipe 3 are all made of the steel pipe punch forming of carbon constructional quality steel, material extends
Property it is good, therefore table body uniform wall thickness, flow consistency are good, and production process is generated without exhaust gas, are suitble to produce in enormous quantities.Inlet opening with
Apopore is using laser cutting, to preferably guarantee part processing precision.All connection parts are all made of advanced laser welding
Technique, to guarantee welding precision, intensity, compactness.Since the depth of ontology of the invention is shallower, round steel can be also directlyed adopt
Plate punch forming can save the process for welding small round plate 12 as shell bottom；Certainly, round plate also uses high-quality carbon structure
Steel.
Water meter case of the present invention loads onto the structural members such as machine core, rubber ring, water gage glass, PVC gasket, water meter cover, is exactly
A complete water meter.Tap water enters from the inlet, and by water meter movement, flows out, is can be realized to water from water outlet
Metering.It connects between each part of water meter case of the present invention and is all realized by advanced laser welding process, to guarantee welding essence
Degree, intensity, compactness.Water meter case of the present invention is adapted to the manufacture big machine core water meter of wet type, work water pressure≤1.0MPa, medium
Generally tap water.
