Abstract
The utility model discloses a malleable steel tap water pipe fitting with an outer galvanized layer and an inner plastic coating layer. The malleable steel tap water pipe fitting with an outer galvanized layer and an inner plastic coating layer is composed of an outer galvanized layer, a malleable steel pipe fitting, and an inner plastic coating layer. The utility model relates to is suitable for being matched with a steel-plastic composite pipe to be used.
Description
The utility model relates to the production technology of water pipe, a kind of specifically external galvanized layer internal plastic coating tap water malleable cast iron pipe fitting.
The running water pipe of potable water adopts galvanized pipe always, because this material can cause the pollution of water, people's health worked the mischief, so some place galvanized pipe of having ordered to ban use of.What replace this material is steel-plastic composite pipe, still, does not still have in the market with steel and moulds the matching used pipe fitting of compound quantity.
The purpose of this utility model provide a kind of can with the matching used pipe fitting of steel-plastic composite pipe.It meets modern sanitary standard, can be so that running water system water quality is not contaminated because of tubing.
The technical solution of the utility model is as follows:
In common external galvanized layer pipe fitting, adopt the method for plastic-coated, non-toxic plastic is coated in pipe fitting inner wall, make it to cover evenly.Making the utility model become three-decker, promptly is coating layer, malleable cast iron pipe fitting from the inside to surface, zinc coat.
The utility model has the advantages that product meets modern sanitary standard, and corrosion-resistant, good seal performance, low cost of manufacture.
Below in conjunction with accompanying drawing the utility model is further explained:
Fig. 1 is the structural representation of tap water tee pipe fitting;
Fig. 2 is the structural representation of tap water bend pipe tools;
From Fig. 1, Fig. 2 as can be known, the utility model is a kind of Pipe fitting with composite layers, and pipe fitting inner wall has one deck coating layer 1, and middle one deck is a malleable cast iron pipe fitting 2, and outside one deck is a zinc coat 3.
The internal plastic coating layer of present embodiment is selected polyethylene for use.
