Abstract
The utility model belongs to the technical field of air conditioner refrigeration systems, and particularly relates to a joint suitable for a pipeline of a refrigeration system, which solves the problems of inconvenient installation, bad sealing performance and the like of the existing joint. The joint comprises a joint nut, wherein a first barrel-shaped body with a first external thread is arranged at one end of the joint nut, and a second barrel-shaped body with a second external thread is arranged at the other end of the joint nut. The joint is characterized in that a first through hole which is axially formed is formed in the first barrel-shaped body; a second through hole which is axially formed and communicated with the first through hole is formed in the second barrel-shaped body; the hole diameter of the first through hole is equal to the hole diameter of the second through hole; and the outer diameter of the first barrel-shaped body is greater than the outer diameter of the second barrel-shaped body. Compared with the prior art, the joint suitable for the pipeline of the refrigeration system has the advantages of being simple in structure, convenient to install, good in sealing performance, not easy to generate a leakage phenomenon, suitable for connection for tube bodies with different outer diameters, high in strength, and long in service life.
Description
Technical field
The utility model belongs to the air-conditioning refrigeration system technical field, especially relates to a kind of joint that is applicable to refrigeration system pipeline.
Background technique
Along with the raising day by day of people's living standard, it is increasingly mature that air-conditioning refrigeration system develops.At the air-conditioning refrigeration system middle joint, it is a kind of important accessory; it be mainly used between tube and tube or pipe and equipment between be connected; in order to guarantee gas or liquid state in body, do not leak; joint must have sealing preferably, thereby but existing joint often can the phenomenon of leaking closely not occur owing to connecting when mounted.Except outside existing joint also exist: complex structure, inconvenience is installed, can't connect the problem such as intensity is low between the different body of external diameter.
The problem existed in order to solve prior art, people have carried out long-term exploration, have proposed solution miscellaneous.For example, Chinese patent literature discloses a kind of metal joint [application number: 201220442950.6], comprises main body, and the main body two ends have respectively outside thread, it is characterized in that outside thread and urgent nut are connected by flexible pipe, outside thread and nut threaded.
Such scheme has solved the poor problem of existing joint tighness to a certain extent, but this scheme still exists: complex structure, inconvenience is installed, and can't connect the problem that intensity is low between the different body of external diameter.
Summary of the invention
The purpose of this utility model is for the problems referred to above, provides a kind of simple and reasonable, easy for installation and can connect the joint that is applicable to refrigeration system pipeline of the body of various outer diameter.
For achieving the above object, the utility model has adopted following technical proposal: the joint that originally is applicable to refrigeration system pipeline, comprise Female connector fittings, described Female connector fittings one end is provided with has first externally threaded the first cylinder, the other end is connected with has second externally threaded the second cylinder, it is characterized in that, be provided with the first through hole of axial setting in described the first cylinder, the second through hole that is provided with axial setting in described the second cylinder and is connected with the first through hole, the aperture of described the first through hole equals the aperture of the second through hole, the external diameter of described the first cylinder is greater than the external diameter of the second cylinder.
In the above-mentioned joint that is applicable to refrigeration system pipeline, the external diameter 1.5-2 that the external diameter of described the first cylinder is the second cylinder doubly.
In the above-mentioned joint that is applicable to refrigeration system pipeline, the center line of described the first through hole overlaps with the center line of the second through hole.
In the above-mentioned joint that is applicable to refrigeration system pipeline, described the second cylinder end is provided with the conical head be connected as a single entity structure with the second cylinder.
In the above-mentioned joint that is applicable to refrigeration system pipeline, described the first cylinder is provided with the first seal ring, and described the second cylinder is provided with the second seal ring, and described the first seal ring and the second seal ring lay respectively at the both sides of Female connector fittings.
In the above-mentioned joint that is applicable to refrigeration system pipeline, described Female connector fittings, the first cylinder and the second cylinder are made by brass material.
Compared with prior art, the advantage that originally is applicable to the joint of refrigeration system pipeline is: simple in structure, easy for installation, good airproof performance, be difficult for leakage phenomenon occurs, and is applicable to the connection of various outer diameter body, and intensity is high, long service life.
The accompanying drawing explanation
The structural representation that Fig. 1 provides for the utility model.
In figure, Female connector fittings 1, the first cylinder 2, the first outside thread 21, the second cylinder 3, the second outside thread 31, the second through hole 32, conical head 33, the first seal ring 4, the second seal ring 5.
