Preferably, the thread groove port of the connector body is set fluted, and embedded O-ring, works as institute in the grooveWhen stating connector body and being alignd with the mouth of pipe of the hole pattern steel strip-plastic multiple tube, the O-ring is located at hole pattern steel band modelingBelow the hole pattern steel band for expecting multiple tube.
Preferably, the internal diameter of the connector body is equal to the internal diameter of the hole pattern steel strip-plastic multiple tube.
Preferably, the first cutting ferrule nut is identical with the specification of the second cutting ferrule nut, and first cutting ferruleThe bottom diameter of nut is equal to the external diameter of the cutting ferrule.
Preferably, it is described to treat adapter for one kind in hole pattern steel strip-plastic multiple tube or PE multiple tubes or PP multiple tubes.
Compared with prior art, the beneficial effects of the invention are as follows：
1st, the present invention is compact-sized, installation, convenient disassembly, close by connector body and hole pattern steel strip-plastic multiple tubeConnection, the sealing property of junction, and the seal assembly by being socketed outside connector body are improved, is realized well secondary closeEnvelope, improve the overall sealing property of device；
2nd, connector body of the invention is identical with the caliber between hole pattern steel strip-plastic multiple tube, and keeps close patchClose, so as to ensure that the inner-walls of duct of pipeline junction is smooth, do not influence circulation area；
3rd, present invention mounting O-shaped rings on connector body, current and hole pattern steel band are isolated from one another, so as to avoid hole patternSteel band is corroded, and improves the service life of hole pattern steel strip-plastic multiple tube；
4th, squeezing action of the present invention using cutting ferrule nut to rubber ring, extruding of the cutting ferrule nut to cutting ferrule is on the one hand reducedDestroy, cutting ferrule inner edge is equably cut the threaded port of connector body, form effectively sealing.
