Abstract
The utility model relates to a pipe fitting for double hot melt metal plastic composite pipes. The utility model is composed of a metal lining, a body plastic composite pipe fitting and a metal insert, wherein inner screw threads are arranged in the metal insert. The utility model is characterized in that the metal lining and the metal insert are formed in one piece in the body plastic composite pipe fitting after integral injection molding; one end of the metal lining and a metal plastic composite fitting requiring connection are tightly fused together in a hot melt mode to form a whole body; one end of the metal insert and the metal plastic composite fitting requiring connection are connected in a screw thread mode. The utility model has the advantages of simple and reasonable structure, good chemical stability, multiple varieties, light weight, labor-saving operation and no required antiseptic treatment and is especially suitable to be used in construction sites.
Description
Technical field
The utility model belongs to a kind of pipeline pipe fitting, is a kind of pair of fuse metal plastic composite pipe pipe fitting specifically.
Background technique
Pipe fittings such as cast iron, cast steel, copper are used in connection between the metal current plastic composite pipe always, Placement mainly adopts machinery types such as clamp-press type or differential formula to connect, it is many that preservative treatment, relatively poor, the required accessory of chemical stability, Sealing need be carried out in its Placement surface, and medium tache multioperation complexity, arbitrary accessory are not in place and all can cause seepage.And existence can only be used for the connection between the composite metal-plastic pipe, defective that can not be general.
Summary of the invention
The purpose of this utility model provides and a kind ofly need not to carry out preservative treatment, need not medium tache, and can be used for connection between the composite metal-plastic pipe, can be used for the two fuse metal plastic composite pipe pipe fittings that are connected between composite metal-plastic pipe and the metal tube again, to overcome above-mentioned deficiency.
To achieve these goals, the utility model is made of metal lining, main body plastic composite pipe and metal insert, wherein be provided with internal thread in the metal insert, be characterized in: metal lining and metal insert through the integral molded plastic once-through in the main body plastic composite pipe, the employing hot melting mode closely is welded together between metal lining one end and the composite metal-plastic pipe that needs to be connected, forms an integral body; Adopt the engage thread connection between metal insert one end and the metal tube that needs to be connected.
Major advantage of the present utility model be simple and reasonable, chemical stability good, and is wide in variety, can be connected, integral sealing good sealing effect with plastic tube, composite metal-plastic pipe, metal tube combination in any.Overcome present composite metal-plastic pipe commonly used cast iron, cast steel, copper pipe fitting chemical stability relatively poor, can only be used for composite metal-plastic pipe, the shortcoming of complicated, sealing effect difference and in light weight, rapid operation are installed, need not to carry out any preservative treatment.Being particularly suitable for the job site uses.

Among the figure: external port, 5-main body plastic composite pipe, 6-metal insert, 7-metal tube, the 8-conical surface in 1-composite metal-plastic pipe, 2-metal lining, 3-air vent, the 4-.
Embodiment
Further specify the utility model below in conjunction with accompanying drawing.
The utility model is moulded (or other metallo-plastic) composite pipe 1, metal lining 2, main body plastic composite pipe 5, metal insert 6, zinc-plated or Stainless Steel Tube 7 formation (see figure 1)s by steel.The inside and outside wall of plastic composite pipe 1 port and the interior external port of main body plastic composite pipe 5 are to adopt hot melting mode closely to be welded together simultaneously, form an integral body, and the utility model pipe fitting comprises sleeve, elbow, threeway (see figure 2) and four-way etc.The air vent 3 of design on the utility model main body plastic composite pipe 5, the length of air vent 3 equals the length of the required welding of composite pipe 1 outer wall, is convenient to discharge residual air in the welding annular groove in fusion process, avoids forming pore, improves join strength.The interior external port 4 that the utility model main body plastic composite pipe 5 is connected with composite metal-plastic pipe 1, external port is short, inner port is long, make welding light more, be convenient to observe the welding effect.The composite pipe fitting that the utility model is all and two faces of composite metal-plastic pipe inner and outer surface thermofusible spigot are designed to the conical surface 8, realize that band is pressed connection in the reflow process, make welding more firm, attractive in appearance.Metal insert 6 on the utility model main body plastic composite pipe 5 after the integral molded plastic moulding, can pin the degrees of freedom of all directions, makes it to become as a whole with plastic composite pipe.The utility model to increase the plastic composite pipe mechanical strength, improves the reliability of welding at pipe fitting inner wall inner liner metal pipe box 2 (integral molded plastic moulding).
The utility model steel-plastic composite pipe is at first with the dedicated pipe cutter steel to be moulded pipe to cut by Len req with the Placement of two hot melt composite pipe fittings, with special-purpose full circle, flaring tool steel is moulded the tube opening inwall then and carries out full circle, enlarging processing and should guarantee that tubing welding section must not be stained with greasy dirt, water and dust and other impurities.Next is to select suitable electric heat welding instrument for use and mix special-purpose welding die head, plugs in, and opens heater switch and heats, and treats can carry out when temperature reaches set point of temperature the welding work of steel-plastic composite pipe and two hot melt composite pipe fittings.Steel-plastic composite pipe and two hot melt composite pipe fittings are inserted in the special-purpose welding die head that has heated simultaneously, steadily, suitably exert pressure, when treating that steel-plastic composite pipe is fused to the degree of depth of regulation with two hot melt composite pipe fittings, be incubated several approximately seconds, (being as the criterion to see the plastics molten bath) promptly should extract steel-plastic composite pipe steadily, apace simultaneously and also should in time, steadily, apace steel-plastic composite pipe be inserted in two hot melt composite pipe fittings with two hot melt composite pipe fittings.Attention: in the process of inserting, can't be crooked, distortion, rotate, and want one to be inserted into the end, guarantee coaxality, perpendicularity, the parallelism of tubing and pipe fitting.
