Abstract
The invention discloses a pipe processing method for improving the sealing performance between a metal insert and a plastic material, which comprises a step of making the metal insert and a step of injecting the plastic material onto the periphery of the metal insert and molding, wherein in the step of making the metal insert, a plurality of annular grooves are formed on the outer circumference of the metal insert, at least one of the annular grooves is an annular narrow groove of which the width is smaller than half of the width of the widest annular groove; and the plastic is filled in the annular narrow groove first and then filled into other annular grooves. The plastic material filled in the annular narrow groove can strengthen the anti-leakage effect. Meanwhile, the annular narrow groove is narrower and the axial shrinkage of the plastic material filled in the annular narrow groove is relatively small in comparison with other annular grooves, so that the slight axial movement of a plastic pipe and the metal insert can be effectively restrained to further strengthen the sealing effect.
Description
Technical field:
The present invention relates to mechanical field, relate in particular to piping element, particularly a kind of pipe fitting processing method that improves sealability between damascene part and the plastic material.
Background technique:
Plastic cement pipe fitting product is mantle fiber directly, runs into the occasion that is threaded and just need adopt threaded damascene part in the plastic cement pipe fitting.In the prior art, the hoop groove is set on the excircle of damascene part, when the outside of damascene part injection moulding plastic cement pipe fitting, plastic cement enters in the hoop groove, thus the mechanical connection and the sealing of realization and damascene part.But the expansion coefficient of metallic material and plastic material differs greatly, and the plastic cement pipe fitting is generally thick walled casting, shrinks more significantly, and the plastic cement pipe fitting causes plastic parts and metallic material partly to be peeled off after shrinking probably, thereby causes seepage.
Summary of the invention:
The object of the present invention is to provide a kind of pipe fitting processing method that improves sealability between damascene part and the plastic material, the pipe fitting processing method of sealability will solve in the prior art the unfavorable technical problem of sealing condition between the plastic cement pipe fitting and damascene part between described this raising damascene part and the plastic material.
The pipe fitting processing method of sealability comprises a step and a step that plastic material is expelled to damascene part periphery and moulding of making the damascene part between this raising damascene part of the present invention and the plastic material, in the step of described making damascene part, on the excircle of damascene part, be arranged to few two hoop grooves vertically, wherein, in the step of described making damascene part, the narrow groove of at least one hoop is set on the excircle of described damascene part, the width of the narrow groove of described hoop is less than 1/2nd width of the wideest hoop groove, in the described step that plastic material is expelled to damascene part periphery and moulding, plastic material elder generation packing ring to narrow groove, is recharged all the other hoop grooves.
Further, described damascene part is a pipe member.
Further, an end of described damascene part is provided with internal thread or outside thread, the adjacent setting of the other end of narrow groove of described hoop and damascene part.
Working principle of the present invention is: the plastic cement pipe fitting is when the injection moulding of the outside of damascene part, plastic material elder generation packing ring is to narrow groove, recharge all the other hoop grooves, thereby guaranteed effective filling of the narrow groove of hoop, the narrow groove of hoop can strengthen the effect of leakage proof.Simultaneously, the narrow groove width of hoop is less, and all the other hoop grooves are little relatively for the axial shrinkage of filling plastic material wherein, and it is moving to limit string axially micro-between plastic cement pipe fitting and the damascene part effectively, thus the further effect that strengthens sealing.
The present invention and prior art compare, and its effect is actively with tangible.The present invention is provided with a narrow groove of hoop on the excircle of damascene part, the width of the narrow groove of hoop is less than 1/2nd width of the wideest hoop groove, the plastic cement pipe fitting is when the injection moulding of the outside of damascene part, plastic material elder generation packing ring is to narrow groove, recharge all the other hoop grooves, thereby guaranteed effective filling of the narrow groove of hoop, the narrow groove of hoop can strengthen the effect of leakage proof.Simultaneously, the narrow groove width of hoop is less, and other hoop grooves are little relatively for the axial shrinkage of filling plastic material wherein, and it is moving to limit string axially micro-between plastic cement pipe fitting and the damascene part effectively, thus the further effect that strengthens sealing.
Description of drawings:
Fig. 1 is the cross-sectional schematic of the damascene part among the present invention.
Embodiment:
Embodiment 1:
