The utility model solves its technical problem and can also adopt following technical measures further to realize.
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the junction surface of flange holder and the normal plane of its axis have angle.
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the electrical heating wire of flange holder inside is located on the inwall of flange holder.
The electric heating of above-mentioned connection plastic tube melts the flange holder, wherein, the angle of the normal plane of flange holder junction surface and its axis more than or equal to 0 ° smaller or equal to 30 °.
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the flange holder is provided with the front end seam or/and the rearward end seam.
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the electrical heating wire of flange holder inside vertically is laid on the inwall of flange holder, and the outer wall of flange holder is provided with through hole.
The electric heating of above-mentioned connection plastic tube melts the flange holder, wherein, is provided with wiring terminal in the described through hole.
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the width of the electrical heating wire of flange holder inside is smaller or equal to the width of flange holder; Be provided with metal lining in the through hole; The periphery of wiring terminal is provided with plastic protective sleeve.And,
The electric heating of above-mentioned connection plastic tube melts the flange holder, and wherein, the plastic protective sleeve quantity of the through hole in the flange holder, wiring terminal is at least 2.
The utility model compared with prior art has tangible advantage and beneficial effect.By above technological scheme as can be known, the utlity model has following advantage:
It is more reliable, firm that the existence of flange boss makes that flange connects.The inner distribution electrical heating wire of the flange holder of plastic article is the connection of adopting the molten mode of electric heating, and this kind connection can not produce overlap in that tubing is inner, can not influence negotiability, and easy construction, cost are low, have improved manufacturing efficiency greatly.The existence of the angle of the junction surface of flange holder and the normal plane of its axis has compensated the molten contraction that connects back tubing of electric heating, makes the tubing junction surface Paint Gloss smooth and connect more firm, more convenient.
The flange holder that this kind method is made has the characteristics simple, easy to connect, that cost is low of making, and can install by site operation, has saved human and material resources greatly.For example: the utility model is applied on plumbing, air-supply, whitewashing and the gas pumping pipe on the special industries such as colliery, human and material resources can have been saved greatly, and welding quality height, speed be fast, do not have overlap, the tubing bearing capacity that welds out is strong, interchangeability is good, can satisfy the requirement of all trades and professions.
Below in conjunction with drawings and Examples the utility model is further described.
