Description

U-shaped integrated elbow pipe connected with gas meter

Technical Field

The utility model relates to a gas table installation field, especially a U-shaped integration return bend of connecting gas table.

Background

In the gas construction, the elbow used for connecting the gas meter is an indispensable part, especially the existing U-shaped elbow, the U-shaped elbow is formed by connecting straight pipes through elbows, because the shape of the elbow needs, at least two elbows are adopted to connect three straight pipes, which means that the installation of the elbow needs to be finished firstly in the connection process of the elbow structure, thus greatly increasing the installation steps, and in the installation process, the sealing adhesive tape needs to be wound when the elbow and the straight pipe are connected, thus prolonging the installation time; in addition, because the number of the adopted connecting pipe fittings is large, the number of leakage points of the whole bent pipe is large.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problem, a U-shaped integrated elbow for connecting a gas meter is designed.

Realize above-mentioned purpose the technical scheme of the utility model be, a connect U-shaped integration return bend of gas table, the connecting pipe comprises a connecting pipe, the port department processing of connecting pipe one end has the connector, the connecting pipe is crooked 180 degrees, both ends after the connecting pipe is crooked are parallel to each other, and the intermediate junction section is semi-circular.

The connecting pipe is a galvanized steel pipe.

And the other end of the connecting pipe is provided with a connecting thread.

The connector is used for connecting the gas inlet or the gas outlet of the gas meter.

Advantageous effects

Utilize the technical scheme of the utility model name of preparation, whole return bend structure as an organic whole need not to adopt the mode that straight tube and elbow are connected, the effectual required step and the part quantity of installation return bend that has reduced, and the staff only need be connected the both ends and the gas table of return bend and other gas pipes, need not to implement the connection process of straight tube and elbow, has improved the convenience and the work efficiency of gas return bend installation.

in the figure, 1, a connector; 2. a connecting pipe; 3. a connecting section; 4. a straight pipe; 5. and (4) bending the pipe.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-2, the present application is characterized in that the connecting tube is bent 180 degrees, the bent ends of the connecting tube are parallel to each other, and the middle connecting section is semicircular.

In the prior art, the gas elbow is formed by connecting three straight pipes 4 and two elbows 5 as shown in fig. 2, which leads to the fact that the gas meter and the gas pipe can be connected only after the straight pipes and the elbows are connected to form the elbow shape in the installation process of the whole elbow, the screw connection action must be repeated when the elbows and the straight pipes are connected, and meanwhile, sealing belts are continuously wound at the connection positions, which wastes time and materials.

Compared with the prior art, this application is integrated structure, need not to adopt the straight tube to be connected with the elbow and forms the process of return bend, and whole connecting pipe does not have any unnecessary installation, and this just means, this application return bend structure only need in the installation with the both ends of return bend direct with gas table and gas union coupling just can, need not the connection step of return bend itself, the effectual installation time that reduces the return bend, and then improved the work efficiency of installation.

As a preferable scheme, further, the connecting pipe is a galvanized steel pipe, the original bent pipe is made of a cast iron material, and an anti-corrosion coating is coated on the surface of the original bent pipe, and the original cast iron pipe cannot achieve the bending effect required in the application, so that the technical scheme of the application cannot be achieved.

Preferably, the other end of the connecting pipe is provided with a connecting thread for connecting a gas delivery pipe.

As a preferred scheme, furthermore, the connector is used for connecting an air inlet or an air outlet of a gas meter.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
