Description
Technical Field
The invention relates to a quick connector, in particular to a quick connector for a gas household pipeline.
Background
The pipeline for gas to enter the house is made of hard material, such as metal pipe or hard plastic pipe, a certain length is reserved after the gas enters the house, indoor appliances are connected with the pipeline, generally, the connection between the two hoses is mainly two-way or three-way, and sometimes, a locking device or an iron wire and the like are additionally arranged outside the pipes for screwing. However, in practical use, the connection still has the phenomenon of air leakage, the existing joint cannot solve the problem, and the installation of the existing connecting joint is time-consuming and labor-consuming.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to provide a quick connector for a gas-to-the-home pipeline, which can solve the problem of gas leakage and can realize quick installation.
In order to achieve the purpose, the technical means adopted by the invention is as follows: a quick joint for a gas service pipeline comprises a gas inlet end and at least one gas outlet end, wherein the gas inlet end is a hollow pipe consisting of a large-diameter hollow cylinder, a small-diameter hollow cylinder and a frustum cone connected between the two concentric cylinders, and a sealing ring is arranged in the frustum cone or/and the large-diameter hollow cylinder; the air outlet end is a hollow pipe with a plurality of spacing rings arranged on the outer surface.
Furthermore, the outer surface of the end part of the large-diameter hollow cylinder is provided with threads or a bayonet, a screw cap matched with the threads or a cover with a structure matched with the bayonet is used as a port sealing cover, and a hole penetrating through a household gas pipe is reserved in the center of the sealing cover.
Furthermore, the diameter of an inner hole of the large-diameter hollow cylinder is 1.1-1.3 times of the outer diameter of the gas service pipeline, and the inner diameter of the small-diameter hollow cylinder is in clearance fit with the gas service pipeline.
Furthermore, the end part of the hollow pipe of the air outlet end is provided with a section of conical frustum body for introduction.
Furthermore, a sealing ring is arranged among the plurality of spacing rings at the air outlet end.
Furthermore, the use method of the quick connector for the gas service pipeline comprises the steps of firstly sleeving the sealing cover into the gas service pipeline, then inserting the gas service pipeline into the small-diameter hollow cylinder from the end of the large-diameter hollow cylinder, arranging the sealing ring in the truncated cone or/and the large-diameter hollow cylinder to seal the gas service pipeline, and locking the sealing cover; at the moment, only the indoor gas pipe is inserted into the gas outlet end, and the conical table body of the gas outlet end introduces the indoor gas pipe and inserts the plurality of spacing rings covering the gas outlet end.
The invention has the beneficial effects that: the structure design is simple, the installation and the use are convenient, and the air leakage problem is thoroughly solved.
Drawings
The invention is further illustrated with reference to the following figures and examples.
FIG. 1 is a schematic view of the structure of the present invention.
In the figure: 1. the gas inlet end 11, the large-diameter hollow cylinder 12, the small-diameter hollow cylinder 13, the sealing cover 2, the gas outlet end 21 and the spacing ring.
Detailed Description
As shown in fig. 1, a quick coupling for a gas service pipeline comprises a gas inlet end 1 and at least one gas outlet end 2, wherein the gas inlet end 1 is a hollow pipe consisting of a large-diameter hollow cylinder 11, a small-diameter hollow cylinder 12 and a truncated cone connected between the two concentric cylinders, and a sealing ring is arranged in the truncated cone or/and the large-diameter hollow cylinder 11; the air outlet end 2 is a hollow pipe with a plurality of spacing rings 21 arranged on the outer surface.
The outer surface of the end part of the large-diameter hollow cylinder 11 is provided with threads or bayonets, a nut matched with the threads or a cover matched with the bayonets is used as a port sealing cover 13, and a hole penetrating through a gas pipe entering a household is reserved in the center of the sealing cover 13.
The inner hole diameter of the large-diameter hollow cylinder 11 is 1.1-1.3 times of the outer diameter of the gas service pipeline, and the inner diameter of the small-diameter hollow cylinder 12 is in clearance fit with the gas service pipeline.
The end part of the hollow pipe of the air outlet end 2 is provided with a section of conical frustum body for leading in.
And sealing rings are arranged among a plurality of spacing rings at the air outlet end 2.
The use method of the quick joint for the gas service pipeline comprises the steps of firstly sleeving the sealing cover into the gas service pipeline, then inserting the gas service pipeline into the small-diameter hollow cylinder from the end of the large-diameter hollow cylinder, arranging a sealing ring in the truncated cone or/and the large-diameter hollow cylinder to seal the gas service pipeline, and locking the sealing cover; at the moment, only the indoor gas pipe is inserted into the gas outlet end, and the conical table body of the gas outlet end introduces the indoor gas pipe and inserts the plurality of spacing rings covering the gas outlet end.
Because big hollow cylinder has been designed, add the sealing washer in big hollow cylinder and/or circular truncated cone, set up sealed lid behind the hollow cylinder of major diameter again, let the pipe line of registering one's residence of hard material easily insert and seal, and the end of giving vent to anger can set up to multiple modes such as one-way or tee bend, the one-way structure has only been drawn in this embodiment picture, but the principle is the same, because the indoor hose that is, adopt the circular truncated cone body to introduce, add many spacer rings and sealing ring cooperation, make indoor hose just be in encapsulated situation after inserting. Therefore, the invention solves the problems of quick connection and sealing, and has simple structural design and convenient and quick use.
The embodiments of the present application are only used for illustrating the technical features disclosed in the present application, and the changes made by those skilled in the art through simple replacement still belong to the protection scope of the present application.
