Being provided with the step for placing inner flow passage regulating block and outer flow passage regulating block inside described shell body, below described each step, all forming the chamber for placing raw material, described two charging apertures respectively with two chamber; Described inner housing top is connected with nozzle, described two chambers all with nozzle UNICOM.
Further, described shell body is symmetrically arranged with several for regulating the inner flow passage adjustment screw in inner flow passage regulating block and inner housing gap, described inner flow passage adjustment screw contacts with adjustment inner flow passage regulating block.
Further, described shell body is also symmetrically arranged with the outer flow passage adjustment screw for regulating outer flow passage adjustment module and inner flow passage adjustment module gap, described outer flow passage adjustment screw contacts with outer flow passage adjustment module.
Further, described nozzle comprises the interior nozzle of inside and outside setting and outer nozzle, is provided with the runner flowed out for raw material between described interior nozzle and outer nozzle; Described interior nozzle is connected with inner housing inside thread, and described outer nozzle is threaded with outer flow passage regulating block.
Further, described shell body top is also provided with block, and is fixed by trip bolt; Described outer flow passage adjustment module is provided with step, and described block contacts with outer flow passage adjustment module step surface.
Further, be fixed on inner housing base by trip bolt bottom described shell body.
Further, described inner housing, inner flow passage regulating block, outer flow passage regulating block and shell body are coaxial setting.
Compared with prior art, the utility model has following useful technique effect: by inner housing, inner flow passage regulating block, outer flow passage regulating block and shell body being set gradually from inside to outside and route gap, shell body arranges two steps and forms two independently chambers, shell body arranges two charging apertures and respectively at two chamber, avoids entering of air.At inner housing top, nozzle is set and with two chamber, make adhesive and polyethylene complete compound in head inside, avoid entering of air, thus fundamentally improve adhesive layer and polyethylene layer adhesive strength.By arranging such structure, two cover heads being changed into a set of, saves the occupy-place length of production line, also save processing cost and operating cost simultaneously.When producing different tube diameters steel pipe, only needing replacing head, greatly saving manpower and materials, improve operating efficiency, reduce cost and drop into.
Further, by arranging inner flow passage adjustment screw, can regulate the annular space size of inner flow passage, thus reach the object controlling anticorrosive coat thickness.
Further, by arranging outer flow passage adjustment screw, can regulate the annular space size of outer flow passage, can effectively control anticorrosive coat thickness.
Further, by arranging outer nozzle and interior nozzle, making adhesive and polyethylene can form abundant compound in annular space at nozzle and outer flow passage regulating block and inner housing, further improving crudy.
