Abstract
The utility model discloses a tee joint. A threaded connection section between a left-end joint and a right-end joint extends downwards and is provided with metal threads, a plastic tube is lined in the threaded connection section, an end opening of the plastic tube is turned outwards to cover the outside of an end opening of the metal threads, a base of the metal threads is disposed in a hexagonal transitional section by means of injection molding, at least one through hole communicated with the outside is arranged at the bottom of each of gluing cavities of the left-end joint and the right-end joint, and redundant liquid glue in the left-end gluing cavity is discharged from the through hole during glued connection, thereby bringing great convenience. The plastic tube is lined in the threaded connection section, and the end opening of the plastic tube is turned outwards to cover the outside of the end opening of the metal threads, thereby preventing rusted metal materials from polluting water. The turned end opening of the plastic tube is used for replacing a gasket, so that sealing effect is fine after connection and assembly, and service life is also greatly prolonged.
Description
Technical field
The utility model relates to a kind of pipe fitting, specifically relates to a kind of tee union.
Background technique
In the prior art, in the tee union of pipe fitting, mostly the section of being threaded is fabricated metals, be directly injection-moulded in the hexagonal changeover portion of plastic pipe, the inboard of the section of being threaded is without any liner, the metallic material polluted-water that gets rusty easily also needs to add when connecting and joins pad with the enhanced leaktightness effect.Pad generally is a rubber product, and ageing failure makes be subject to pad the working life of straight coupling easily, brings a lot of inconvenience to the user.
Summary of the invention
The utility model mainly is to solve above-mentioned existing in prior technology technical problem, and a kind of tee union is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of tee union, comprise left end joint, right-hand member joint, extend downwards between the two and be arranged to the section of being threaded, the described section of being threaded is lined with plastic tube body in metal threaded, and the port of plastic tube body outwards turnover covers outside the metal threaded port.
As preferably, described metal threaded matrix is injection-moulded in the hexagonal changeover portion.
As preferably, described left end joint comprises left end connecting end pipe and left end gummed outer wall, is left end gummed cavity between the two, and the bottom of left end gummed cavity is provided with at least one left end through hole, and left end through hole break-through left end glues together outer wall and the external world is conducted; Described right-hand member joint comprises right-hand member connecting end pipe and right-hand member gummed outer wall, is right-hand member gummed cavity between the two, and the bottom of right-hand member gummed cavity is provided with at least one right-hand member through hole, and the right-hand member through hole break-through right-hand member gummed outer wall and the external world are conducted.
The utility model is lined with plastic tube body in the section of being threaded, the port of plastic tube body outwards turnover covers outside the metal threaded port, avoided the metallic material after stain water body that gets rusty like this, plastic tube body port after the turnover has substituted pad, good sealing effect after being linked and packed has also prolonged working life greatly.The utlity model has characteristics such as simple in structure, reasonable in design.
