Description
Technical field
This utility model relates to tubing mould, particularly relates to a kind of multiple tube mould.
Background technology
Along with improving constantly of people's living standard, health and safety is the two principal themes that modern payes attention to the most, drinks
The safety of water and the water quality of domestic water and water pipe particularly becomes focus of concern.Drinking water refers to can be without place
Reason, directly feeds the water that human body is quoted, including the drinking-water required for human body every day and domestic water, wherein, the product of drinking water
Matter is not only relevant with Drinking water quality itself, also relevant with the conveyance conduit of drinking water.From the point of view of quality of drinking water ensures, tap water
Company produces standardized Drinking Water and is transported to huge numbers of families by water supply line, and people usually touch or can
The most water supply line of self-changeable is exactly the flexible pipe carrying drinking water, if described flexible pipe fails safety standards, it will straight
Connect the health having influence on human body.
Owing to people are to improving constantly that the wholesomeness of drinking water requires, it is meant that to flexible pipe healthy requirement
Improve.The rubber commonly used till now from the metal tube in past or plastic flexible pipe, drinking water flexible pipe is towards safety, light, corrosion-resistant
Direction is developed.Due to rubber or the flexibility of plastic flexible pipe, obtain so that described flexible pipe sets at finishing, daily life water at home
Execute the product becoming indispensable in installation, it is adaptable to the soft or position of flexible connection, be used for transmitting kitchen than flexible pipe as will be described
Flexibly connecting in room, drinking equipment, filter plant, bath equipment.Wherein, the drinking water either eaten for people is still
For the drinking water of people's direct physical contact, made safety and sanitation and the people of described flexible pipe by the transmission of described flexible pipe
Healthy closely related company.
Existing flexible pipe wide variety, common rubber or plastic flexible pipe are mostly single layer structure, common are ternary second
The polyethylene (PE) of the third rubber (EPDM), TPV (TPV), thermoplastic elastomer (TPE) (TPE) or monolayer, crosslinking gather
Ethylene (PEX), polrvinyl chloride (PVC), PVC-U (UPVC) etc., when being used alone certain material, it is understood that there may be above-mentioned
The flexible pipe that material prepares there may be flexible not enough, on the high side or do not meets the situation that safe and sanitary needs.As UPVC manages
Freeze proof and temperature capacity the most bad, pvc pipe flexible not enough, in most cases, be more suitable for wireway and blow-off pipe
Road, even if PVC being become soft by additive phthalein, but on human body kidney, liver impact very greatly, is not suitable for transmission and drinks
Water.If being used alone PEX mono-layer tube, the rigidity of body is too high, it is impossible to meet the requirement flexibly connected in small space；As
Fruit is used alone PE mono-layer tube, and hardness therein is excessive, and during water delivery, pipeline is not easy bending, it is difficult at small space
Install；If using single TPV (three is the most flat) material, selling at exorbitant prices causes cost increase, causes purchase volume less, and price
Cheap other kinds of TPV material can not meet again the needs of safe and sanitary.Conventional EPDM pipe has abnormal flavour due to itself,
During long-term use, directly contact with water and may result in harmful substance and be dissolved in wherein, human body is damaged, although
Price is relatively low, but can not meet the needs of safe and sanitary.
Therefore, prior art is badly in need of a kind of the composite of unlike material to be made composite soft tube, and
The mould of simple in construction.
