Description
Technical field
The utility model relates to a kind of bathroom faucet, especially relates to a kind of water tap water channel assembly of plastics encapsulate metal.
Background technique
Heat-proof polythene (PE-RT) resin by the exploitation of Tao Shi (DOW) chemical company, began to be applied to the production of pipeline the earliest before more than 20 year.Heat-proof polythene (PE-RT) resin is the polymer that is got through modification by copolymerization by octene and ethene; Optimized position and the density of octene copolymer monomer on main chain through Molecular Structure Design; Thereby make the PE-RT material keep the good low-temperature resistant and shock resistant performance of conventional polyethylene, give the PE-RT material excellent hydrostatic intensity simultaneously.The PE-RT material does not need complicated crosslinking process, but has therefore kept the heat sealability of hypocrystalline TPO, can adopt connecting of all welding technique.Tao Shi (DOW) chemical company researchs and develops out PE-RT DOWLEX*2388DOW of new generation through U.S. NSF authentication.Being applied in the drinking-water aspect is to accomplish safety.
PE-RT tubing has the following advantages:
1) density is little, light weight.
2) health can not polluted the medium of being carried.
3) internal surface is smooth, non-scaling, breed bacteria not, can Secure Application in fields such as potable water conveyings.Non-scaling, hydraulic characteristic is good.
4) chemically stable has good corrosion resistance to general acid-base material, and chemical resistance is good, non-corrosive, long service life.In operating temperature is that 70 degrees centigrade of pressure are under the 0.4MPa condition, can use safely more than 50 years.
5) thermal conductivity is little, and surperficial condensation is few.
6) hydrostatic intensity is high, has excellent internal pressure-resistant level.
7) need not crosslinked, can fusion weld, connect reliable quick.
8) Green Product, recyclable utilization again.
But therefore PE-RT tubing cause its mechanical strength not enough because pliability is good, and screw thread torsion is poor.
At present, just with PE-RT material tubing, because the pliability of PE-RT pipe is good, cause its mechanical strength not enough, screw thread torsion is poor, does not therefore also use it for water tap water channel assembly.
At present; Water tap water channel parts mainly adopt metallic copper, stainless steel, plastics (interpolation glass fibre) material; These materials have been grown and will have been produced pollution to water quality service time; Can slowly be dissolved in water quality like the lead in the copper, the fiber in the plastics also can be dissolved in the water water quality is produced the contamination hazard health, and is unfriendly to environment simultaneously.
Chinese patent CN2846938 discloses a kind of composite structure water tap that uses metal and plastic or other material; Comprise a body and a clad; This body engages institute by a plurality of metal assemblies such as a cold water road, a hot water road, a water outlet and a valve chamber and constitutes; One end of this cold water road, this hot water road and this water outlet is communicated with this valve chamber; The other end of this cold water road, this hot water road and this water outlet forms the opening that makes current logical at this composite structure water tap respectively, first metal parts at least in this cold water road, this hot water road, this water outlet and this valve chamber; Body engagement is coated on body exterior with the plastic packets coating after accomplishing, and processes the composite structure water tap.
Chinese patent CN201651500U discloses a kind of composite water faucet subject; Described tap main body comprises that inner lead, obturator and shell form; Inner lead has water inlet and osculum; End at water inlet and osculum is equipped with threaded insert, and described obturator is that cement or lime or gypsum are made, and described shell is that plastic materials is made.The tap main body structure is divided into three layers, comprises inner lead, obturator and shell, three layers are adopted three secondary mould manufacturings, and it is raw material that inner lead adopts plastics, through injection mould molding and forming, inner wall smooths such as water inlet, osculum; It is raw material that obturator adopts cement or gypsum or lime, through watering the injection molding form; Shell adopts plastics, by molding and forming.
Summary of the invention
The purpose of the utility model is to problems such as the own mechanical strength deficiencies of existing heat resistant polyethylene material; A kind of deficiency that remedies the mechanical strength of heat resistant polyethylene material own is provided; Can reach the requirement of strength of metallic copper, stainless steel faucet water channel; Can promote heat-proof polythene water channel assembly overall performance, to the water tap water channel assembly of the environment plastics encapsulate metal friendly with human body.
The utility model is provided with metal pipe element, plastic pipe, plastic three-way water channel and plastics encapsulate spare; Said plastic pipe is injection-moulded in the metal pipe element; Metal pipe element is connected with the plastic three-way water channel, and plastics encapsulate spare is fixed together metal pipe element and plastic three-way water channel encapsulate.
Said plastic pipe is injection-moulded in the metal pipe element through the quadric injection mould mode; Said metal pipe element is connected through the snap fit mode with the plastic three-way water channel.
The material of said plastic pipe can adopt refractory polyethylene (PE-RT), PPO (PPO), polyoxymethylene (POM), food-grade polypropylene (PP), high density polyethylene (HDPE) (HDPE), PETG-1, at least a in the 4-cyclohexanedimethanoester ester (PETG) etc.
The material of said plastic three-way water channel can adopt refractory polyethylene (PE-RT), PPO (PPO), food-grade polypropylene (PP), high density polyethylene (HDPE) (HDPE), PETG-1, at least a in the 4-cyclohexanedimethanoester ester (PETG) etc.
