Description

Technical Field

[0001] This utility model belongs to the field of elbows, specifically relating to a gas elbow. Background Technology

[0002] Gas fuels are a general term for gaseous fuels that can burn and release heat for use by residents and industrial enterprises. There are many types of gas fuels, mainly including natural gas, manufactured gas, liquefied petroleum gas, biogas, and coal gas.

[0003] Because gas pipeline installation requires the use of connectors depending on the site, gas elbows are needed at some bends. However, with existing gas elbows, the gas collidees with the inner wall as it passes through the elbow, causing vibrations that can loosen the connection between the elbow and the pipeline, leading to gas leaks. Utility Model Content

[0004] The purpose of this utility model is to provide a gas elbow that solves the problem in the prior art where gas collides with the inner wall when passing through the gas elbow, causing vibration, which leads to loosening at the connection between the gas elbow and the pipeline, resulting in gas leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A gas elbow, comprising:

[0007] Elbow body;

[0008] The elbow has two threaded connectors, both of which are located on the elbow body.

[0009] The connecting mechanism is provided in two sets, and the two sets of the connecting mechanism are symmetrically arranged on the elbow body;

[0012] Fixed components are installed on the elbow body;

[0013] The connecting rod component is mounted on the fixed component.

[0014] As a preferred embodiment of this utility model, each set of fixing components includes an internal threaded sleeve and an external threaded cylinder. The external threaded cylinder is fixedly connected to the circumferential surface of the elbow body, and the internal threaded sleeve is threadedly connected to the external threaded cylinder.

[0015] As a preferred embodiment of this utility model, each set of connecting rod components includes a limiting ring and a connecting rod. The limiting ring is movably sleeved on the external threaded cylinder and is located between the internal threaded sleeve and the external threaded cylinder. There are two connecting rods, both of which are fixedly connected to one side of the limiting ring and both of which movably pass through the external threaded cylinder and extend to the outside of the external threaded cylinder.

[0016] As a preferred embodiment of this utility model, each clamping mechanism includes a locking screw and a mounting ring. The mounting ring is fixedly connected to the same side end of the two connecting rods. Three locking screws are provided, each of which is threaded onto the circumferential surface of the mounting ring, and each locking screw rotates through the mounting ring and extends to the outside of the mounting ring.

[0017] As a preferred embodiment of this utility model, the elbow body and the two threaded connectors are integrally formed.

[0018] In a preferred embodiment of this invention, the inner diameter of the mounting ring is larger than the outer diameter of the elbow body.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. In this solution, the installation ring is used to fit onto the gas pipeline, and the locking screw is threaded onto the installation ring so that the locking screw can press against the gas pipeline, thereby clamping the gas pipeline. The connection mechanism and clamping mechanism can improve the stability of the pipeline connection, so that when the gas flow inside the elbow body vibrates, the connection is prevented from loosening due to vibration, thereby reducing the impact of vibration on the pipeline connection.
