Description
Technical field
The utility model relates to the electric smelting mouthing steel-plastic composite pipe accessory of a kind of embedded electric heating wire in the plastic shaping manufacture field.
Background technique
In existing Steel-plastic pipeline system mounting technique, the mode of electric smelting sleeve fusion weld is adopted in permanent connection between pipe fitting, the tubing more: both tubing and pipe fitting end were processed into the not socket form of charged heated filament respectively, during connection pipe fitting or straight tube end are inserted respectively in the special-purpose electric smelting sleeve, utilize the outer surface of electric smelting sleeve interior surface electric heating wire fusing tubing or pipe fitting insertion end, thereby realize that fusion weld connects.This connecting mode, though fitting structure is comparatively simple, each joint is all wanted electric smelting sleeve of adapted, has significantly increased link cost; Simultaneously, be to guarantee insertion end and electric smelting sleeve no-float, pipe fitting end need pass through secondary turning or one section sealing layer of molding and forming, makes the consistent size of itself and electric smelting sleeve diameter, therefore satisfy the quality of fit requirement, make Steel-plastic pipeline connect that operation increases, complex process; In addition, the pipe fitting skeleton spreads all over the body total length except that the end face plastic layer, can not increase as required or shorten, and makes the skeleton position structure form potential leak point in the melting zone, causes defectives such as wayward, the easy generation leakage of welding process.
Summary of the invention
In order to reduce cost of production and the attended operation difficulty that Steel-plastic pipeline connects, avoid the joint to leak, the utility model provides a kind of electric smelting mouthing steel-plastic composite pipe accessory of embedded electric heating wire.This accessory does not need special-purpose electric smelting sleeve and to the secondary operations of pipe end, main pipe body connects convenient and quick construction, has reduced the production cost and can avoid the joint to leak again simultaneously.
The technical solution of the utility model is: a kind of electric smelting mouthing steel-plastic composite pipe accessory of embedded electric heating wire, the tube wall that comprises threeway or elbow-shaped plastic substrate, tube wall is embedded with Steel Skeleton, wherein, the endoporus of tube wall has joint socket near port position, the internal diameter of joint socket and the tube outer diameter that is connected coupling, and the inwall of joint socket is full of electric heating wire, electric heating wire is connected with wiring terminal, and wiring terminal places in the port of tube wall; Described Steel Skeleton extends in the sidewall of joint socket.
There is stiffening rib corner at described tube wall, and stiffening rib is fixed as one with the Steel Skeleton that is embedded in the tube wall; The elbow corner α of described tube wall is 5 °～90 °; The internal diameter of each the connecting end joint socket on the described accessory can be isometrical, also can be reducing.
The beneficial effects of the utility model are: because the end of this steel-plastic composite pipe accessory is a faucet structure, single injection-molded, its internal diameter and the tube outer diameter coupling that is connected, and the joint socket inwall is full of electric heating wire, and by copper wiring terminal as electrode contacts, to the inwall of the outer wall of socket joint tubing and this steel-plastic composite pipe accessory fusion weld of switching on, from function replaced traditional steel-plastic composite pipe connect used special-purpose electric smelting sleeve, reduced the production cost; And the pipe end that is connected is without secondary operations, and the welding of just can switching in the joint socket is directly inserted in the main pipe body end, makes convenient and quick construction; And be complete one after this accessory and the main pipe body fusion weld that is connected, thoroughly stopped in the existing interconnection technique from pipe fitting side melting welding face reveal may; In addition, accessory also comprises the elbow that corner is different, and each joint socket can be isometrical or reducing on the accessory, thereby has enlarged the Applicable scope of this accessory.
