Description
Technical field
The present invention relates to a kind of water meter, relate in particular to the stainless watermeter shell of a kind of lightweight.
Background technology
The case material of at present conventional water meter has six kinds, but all has different shortcomings, in application practice, to user, has brought many problems.
1, cast stainless steel: high energy consumption high pollution, machine work difficulty is large, and cost is high;
2, brass: China produces the less country of copper, a lot of enterprises are for reducing costs, the overproof lead that adds in copper material, most brass water meter lead compositions all exceed standard, and easily cause children blood lead poisoning;
3, spheroidal-graphite cast iron: cutting characteristic is poor, still can get rusty, and can cause the secondary pollution of water supply;
4, aluminium alloy: after meeting water, can produce aluminium oxide, be senile dementia main cause a disease because of;
5, all types of plastic: can be aging rapidly after ultraviolet long-term irradiation, thereby reduce, housing is withstand voltage forces the way across;
6, stretching stainless steel, is the substitute of cast stainless steel, and cost is still higher, and needs welding, the easy corrosion of solder joint, the easy spalling of solder joint when freezing.
Summary of the invention
The technical problem to be solved in the present invention is, for overcoming the deficiencies in the prior art, to provide a kind of stainless watermeter shell of employing lightweight of cheapness.
The technical solution used in the present invention is: the stainless watermeter shell of a kind of lightweight, by upper shell, lower house and movement, formed, and it is characterized in that:
Described upper shell comprises metal casing, plastic internal cavity, O type circle and toughened glass panel, and metal casing is in upper shell outside, and plastic internal cavity is in upper shell the inside, and O type snare is on toughened glass panel, and toughened glass panel is at upper shell end face.
Described lower house comprises metal casing, plastic internal cavity and two knurlings adapters, and metal casing is in lower house outside, and plastic internal cavity is in lower house the inside, and two knurlings are taken over the both sides at lower house.
In the mouth periphery of described plastic internal cavity, be provided with groove, for the insertion of upper shell plastic internal cavity mouth.
Described core device is at lower house.
Injected plastic glue in the groove of lower house plastic internal cavity, the plastic internal cavity mouth of upper shell inserts in the groove of lower house plastic internal cavity, and upper shell and lower house complete and are sealing adhesive.
Upper shell is injection molded, its method: first by the stainless steel stretched drawing of lightweight for described metal casing, again metal casing is put into mould of plastics as inserts, carry out injection moulding, after the demoulding, plastics in upper shell are exactly plastic internal cavity, finally cover are had the toughened glass panel of O type circle to be pressed into plastic internal cavity.
The edge, below of described metal casing, inside crimping, the edge of its upper opening, also inside crimping, object is as inserts, can have good engagement in order to ensure metal casing with plastic internal cavity.
Lower house is injection molded, its method: first by the stainless steel stretched drawing of lightweight for described metal casing, again metal casing and two knurlings adapters are put into mould of plastics as inserts, carry out injection moulding, after the demoulding, plastics in lower house are exactly plastic internal cavity, and two knurlings are taken at the two ends of lower house, as the import and export of tap water.
The edge, top of described metal casing, inside crimping, object is can have good engagement in order to ensure metal casing with plastic internal cavity during as inserts.
The invention has the beneficial effects as follows high-quality low-cost:
(1) there is outward appearance and the corrosion resistivity of stainless steel water meter, can not cause the secondary pollution to water quality;
(2) solve the easy aging blemiss of plastic water meter ultraviolet radiation resisting, guaranteed life of product;
(3) realize product low cost;
(4) without inside, stainless steel accessory is installed and can be realized good fit with movement;
(5) housing processing, without taking out in mould, realizes efficient injection moulding, enhances productivity.
