Abstract

The utility model relates to an electric-smelting reducing pipe sleeve. The electric-smelting reducing pipe sleeve comprises a framework, the framework consists of an inner framework and an outer framework, the inner framework and the outer framework are of a large-small aperture type structure, that is, one end of the inner/outer framework is of large aperture, and the other end of the inner/outer framework is of small aperture; an alloy wire is wound around the inner framework, and the outer framework is fixed on the inner framework through injection moulding; two ends of the framework are respectively provided with a copper electrode, and an electrode cap covers each copper electrode and is fixed on the framework; and the framework is provided with an observing hole which is arranged in the large-aperture end of the framework, and an observation hole cap covers the observation hole in a seal manner and is fixed on the framework. The electric-smelting reducing pipe sleeve disclosed by the utility model can carry out transmission and distribution of gas and has the characteristics of stable performance, good sealing performance, long service life, safety and reliability.

Description

A kind of electric smelting reducing pipe box

Technical field

The utility model relates to fuel gas transportation pipeline, mainly is a kind of electric smelting reducing pipe box that rural and urban industry and local-style dwelling houses are carried with combustion gas that is applied to.

Background technique

Existing rural and urban industry and local-style dwelling houses are carried used pipeline with combustion gas, and in use, owing to receive the influence of rugged environment, used pipeline can wear out, thereby combustion gas meeting leakage have certain potential safety hazard, and this seal for pipe joints performance is not good yet.

Summary of the invention

The purpose of the utility model is to overcome the deficiency of above-mentioned existence, and the electric smelting reducing pipe box of a kind of stable performance, good airproof performance, long service life is provided.

The purpose of the utility model is accomplished through following technological scheme, and it comprises skeleton, and described skeleton is configured to by inner frame, dermoskeleton, and this inner frame, outer skeleton are big small aperture formula skeleton, and promptly an end is that large aperture, the other end are the small aperture; Be wound with the alloy silk on this inner frame, outer skeleton is fixed on the inner frame through molding and forming.

As preferably, be respectively equipped with copper electrode on the two ends of described skeleton, this copper electrode upper cover has electrode cap, and this electrode cap is fixed on the skeleton.

As preferably, described skeleton is provided with peep hole, and this peep hole is positioned on the large aperture of skeleton, and this peep hole upper cover has the peep hole cap, and this peep hole cap is fixed on the skeleton.

The effect that the utility model is useful: can carry out the transmission & distribution of combustion gas, have stable performance, good airproof performance, long service life, safe and reliable characteristics.
