90-degrees two-way connector of spiral double-layer heat-preservation metal purging system

Abstract

A 90-degrees two-way connector of a spiral double-layer heat-preservation metal purging system relates to the field of a chimney of a fireplace, and comprises a three-way connector pipe body; the connector pipe body comprises an inner layer, an outer layer and a heat-preservation cotton filled between the inner layer and the outer layer; a ring-shaped convex end closure is welded closely on the upper end opening of the connector pipe body, a ring-shaped concave end closure is welded closely on the lower end opening and side end opening of the connector pipe body, respectively; the heat-preservation cotton is sealed among the inner layer, the outer layer, the ring-shaped convex end closure and the ring-shaped concave end closures; outer screws are arranged on the ring-shaped convex end closure, and inner screws are arranged on each ring-shaped concave end closure. The connector is simple in structure, the purging system is fastened by threaded tight connection, so the rain or steam is prevented completely from entering the heat-preservation cotton of the purging system, meanwhile, the mounting materials like hoops are saved, the mounting efficiency is improved by more than three times than that of the purging system with hoops; the 90-degrees turning connection of the purging system can be realized by the two-way connector disclosed by the invention.

Description

Technical field: [0001] The invention relates to the field of fireplace chimneys, in particular to a 90° two-way connector for a spiral double-layer thermal insulation metal exhaust system. Background technique: [0002] A fireplace is a device that builds a fire against a wall in a room for heating. Fireplaces were originally used in Western countries and have both decorative and practical value. And according to the culture of different countries, it is divided into: American fireplace, English fireplace, French fireplace, etc., so the shapes are different. The basic structure of the fireplace includes: a fireplace frame and a fireplace core. The mantel serves as a decoration. The fireplace core serves a practical purpose. Fireplaces are classified according to different materials: marble fireplaces, wooden fireplaces, imitation marble fireplaces (resin), stacked fireplaces. Fireplace cores are classified according to different fuels: electric fireplaces, real fire fi...

AI Technical Summary

Problems solved by technology

The disadvantage of this connection method is that the insulation cotton at the port easily absorbs moisture in the air in rainy days or when the air humidity is relatively high, which reduces the insulation effect of the chimney, and at the same time increases the weight of the chimney system, which will cause safety hazards
