Abstract
The utility model relates to a conical pipe connector and consists of a pipe body, external conical threads, a U-shaped seal ring, internal conical threads, a nut, a pipe and an annular groove. The pipe body is equipped with the external conical threads, while the nut is equipped with the internal conical threads which are fit into the external conical threads. The U-shaped seal ring is covered on the end surface of the pipe and is inserted into the annular groove of the pipe body. The product is provided with the simple structure, the convenient installation and use, the firm sealing, the good effect, and the low cost, and is convenient in popularization and application.
Description
Technical field: the utility model relates to a kind of conical tube joint.
Background technique: at present, the joint of water supply line has two kinds, and a kind of is copper Bite type fittings, this Bite type fittings is poorly sealed when mounted, and run, drip, leak water phenomenon takes place easily, and the copper rust of going up, material is expensive, bring many worries and trouble for people's life, another kind is a PP-R hot melten type plastic joint, and this pipe joint is installed inconvenient, need be equipped with hot-melting machine and power supply when installing in the building site, can not dismounting use repeatedly after the installation, the cost height can't be applied.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned shortcoming, and a kind of conical tube joint is provided, and it has solved the poorly sealed and hot melten type plastic joint of Bite type fittings problems such as inconvenience are installed.The purpose of this utility model is achieved in that a kind of conical tube joint is made of: pipe fitting, circular cone outside thread, U-shaped seal ring, circular cone internal thread, nut, tubing, circular groove.Pipe fitting is provided with the circular cone outside thread, and nut is provided with the circular cone internal thread, and the circular cone inner screw sheath is contained on the circular cone outside thread, and the U-shaped ring set and inserts in the circular groove of pipe fitting on the end face of tubing.This product structure is simple, and is easy to install, adopts the sealing of U-shaped end face two way sealed circle, and sealing is firm, and effective, cost is low, and is easy to utilize.
Description of drawings:
Accompanying drawing is the half section structural representation of a kind of conical tube joint of the utility model.
1-pipe fitting, 2-circular cone outside thread, 3-U-shaped seal ring
4-circular cone internal thread, 5-nut, 6-tubing
7-circular groove
Embodiment: describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing, a kind of conical tube joint is made of: pipe fitting (1), circular cone outside thread (2), U-shaped seal ring (3), circular cone internal thread (4), nut (5), tubing (6), circular groove (7).Pipe fitting (1) is provided with circular cone outside thread (2), nut (5) is provided with circular cone internal thread (4), circular cone internal thread (4) is sleeved on the circular cone outside thread (2), and U-shaped seal ring (3) is sleeved on the end face of tubing (6), and inserts in the circular groove (7) of pipe fitting (1).
During installation, the end of tubing is inserted in the circular groove of pipe fitting after putting the U-shaped seal ring, tightening nuts then, when nut is tightened gradually because the centripetal force effect of tapered tread, the outside thread of pipe fitting shrinks to the center of tubing gradually, the U-shaped seal ring is pressed in the surface of the external diameter and the internal diameter of pipe fitting tightly, forms firm sealing.The conical tube joint can be made with plastic alloy.
Claims (1)
1. conical tube joint, it is made of: pipe fitting (1), circular cone outside thread (2), U-shaped seal ring (3), circular cone internal thread (4), nut (5), tubing (6), circular groove (7), it is characterized in that: pipe fitting (1) is provided with circular cone outside thread (2), nut (5) is provided with circular cone internal thread (4), circular cone internal thread (4) is sleeved on the circular cone outside thread (2), U-shaped seal ring (3) is sleeved on the end face of tubing (6), and inserts in the circular groove (7) of pipe fitting (1).
