Description

The stainless steel water watchcase

Technical field

The utility model relates to a kind of water meter and uses watchcase, relates in particular to a kind of stainless steel water watchcase.

Background technology

Water meter case mainly contains the watchcase that plastics, cast iron, brass and aluminum alloy material are processed in the market; Above watchcase material respectively has relative merits; But there is following variety of issue respectively in they: plastic meter shell is because the material of plastics is different, levels of audit quality is uneven; Maximum secret worry is an insufficient strength, easy ageing, cracking, and there is the hidden danger of leaking in watchcase; Cast iron materials is that the watchcase of conventional water meter uses maximum materials; But its easy oxidation and rusting; Cause the secondary pollution of water quality, later period maintenance, replacing difficulty adopt the iron-clad water meter case of casting technique in addition owing to need process equipments such as founding, electric furnace; Technology falls behind, the new demand of unfavorable environmental protection low-carbon (LC), so the tap water meter industry has been phased out cast housing; Copper shell water meter is owing to have the characteristics of easy machine-shaping; Therefore occupy leading position in high-end water meter market always; But because copper product also has heavy metal elements such as lead, zinc; The requirement that incompatibility people improve constantly to water supply quality, and the copper valency is high and fluctuation is big, is unfavorable for large-scale promotion application; Aluminium alloy also is the material of the nearest a kind of new preparation water meter of releasing, but because aluminium alloy is prone to oxidation, intensity and poor toughness, still to be tested on serviceable life.

Personnel in the industry know, stainless steel material is because characteristic such as its intensity is high, corrosion-resistant and oxidisability is strong is desirable selection if adopt stainless steel as the material of making the water meter shell.Just because of the high characteristic of stainless steel intensity, so the difficult water meter shell that is processed into existing version of stainless steel is difficult to large-scale production in enormous quantities; And, generally need separately middle part welding one circle interphase in the form of a ring at the die cavity inwall of watchcase because the inwall of water meter shell has interphase in the form of a ring, and interfacial existence more increases the difficulty of processing of stainless steel water watchcase.

The stainless steel water watchcase is also arranged in the market, and this stainless steel water watchcase adopts the wax-loss casting process global formation and forming cavity mostly, and the production efficiency of aforementioned stainless steel water watchcase, high, the difficult realization of expense are produced in batches, are unfavorable for promoting.
