Abstract
The utility model relates to a self-sealing light pipe coupling. The coupling comprises a joint pipe (2), and two compression nuts (1) which are respectively sheathed with the two ends of the joint pipe, wherein the two ends of an inner hole of the joint pipe are bell mouths with outward flarings, and the outer ends of the inner holes of the compression nuts are bell mouths with inward flarings; the bevels of the bell mouths of the inner hole of the joint pipe and the bevels of the bell mouths of the inner holes of the compression nuts are opposite to form a trapezoid inner ring slot in which a trapezoid sealing ring (3) can be placed. Through the adoption of the coupling, when pipelines are in butt joint and seal, the pipelines do not need to be processed, the operation is simple, the coupling can be directly mounted, and the sealing effect is good.
Description
Technical field
The utility model relates to the joint device technical field of structures of carrying gas, liquid medium pipeline.
Background technique
There are a large amount of pipelines of carrying gas, liquid medium in production scene, need dock, seal.Traditional method generally has two kinds, and one is to adopt pipe end welded flange, adds sealing gasket, then uses bolt, nut by flange connect, realizes pipeline docking and sealing.Another kind is to adopt pipe ends mantle fiber, then connects with female adapter, realizes pipeline docking and sealing.These two kinds of methods need to be equipped with the equipment such as welding machine, die head threading machine in the time of operation, when site operation, and complex process, labor intensity is large, and efficiency is low.
Summary of the invention
The purpose of this utility model provide in order to solve the deficiency that above-mentioned prior art exists just a kind of when by pipeline docking and sealing without pipeline is processed, simple to operate, can directly install and the selfsealings light pipe joiner of good sealing effect.
The utility model object is achieved by the following technical solution.
A kind of selfsealings light pipe joiner, include adaptor tube and be set with two gland nuts in adaptor tube two ends, the endoporus two ends of adaptor tube are the outside horn mouth of enlarging, the interior outer end of hole of gland nut is the inside horn mouth of enlarging, and the horn mouth inclined-plane of adaptor tube endoporus and the relative formation in gland nut endoporus horn mouth inclined-plane can be placed the trapezoidal inner groove of ladder-shaped sealing ring.
This light pipe joiner is in the time of connecting pipe, without conveyance conduit is processed, simple in structure, can directly install.Can realize pipeline and extend the function connecting, can guarantee again the sealing of junction point, the maximum withstand voltage 0.8MPa that reaches.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in the figure, these selfsealings light pipe joiner includes adaptor tube 2 and is set with two gland nuts 1 in adaptor tube two ends, the endoporus two ends of adaptor tube are the outside horn mouth of enlarging, the interior outer end of hole of gland nut is the inside horn mouth of enlarging, and the horn mouth inclined-plane of adaptor tube endoporus and the relative formation in gland nut endoporus horn mouth inclined-plane can be placed the trapezoidal inner groove of ladder-shaped sealing ring 3.
While adopting the utility model to connect the pipeline of docking, first put respectively gland nut 1 at adaptor tube 2 two ends, at the in-built upper trapezoid seal ring 3 of trapezoidal inner groove, the pipeline light pipe that will dock again inserts in the hole of fittings body from two ends respectively, finally tighten respectively gland nut from two ends, compresses seal, make it hold light pipe tightly, reach the object of sealing and connection light pipe.
Claims (1)
1. a selfsealings light pipe joiner, it is characterized in that, include adaptor tube (2) and be set with two gland nuts (1) in adaptor tube two ends, the endoporus two ends of adaptor tube are the outside horn mouth of enlarging, the interior outer end of hole of gland nut is the inside horn mouth of enlarging, and the horn mouth inclined-plane of adaptor tube endoporus and the relative formation in gland nut endoporus horn mouth inclined-plane can be placed the trapezoidal inner groove of ladder-shaped sealing ring (3).
