Abstract
The utility model relates to a copper flame arrester, which is welded by a copper pipe and a low carbon steel pipe, or a copper pipe and a steel or a copper ring flange. The copper flame arrester adopts the principle that the copper pipe transfers and diffuses heat quickly, once somewhere of the pipeline is on fire, the copper pipe arranged in the oxygen transferring line can prevent the spreading and diffusing of the fire, and avoids the fire hazard and the blasting accidents. The copper flame arrester has the advantages of simple structure, easy manufacturing and arrangement.
Description
The utility model relates to a kind of copper spark arrester, belongs to oxygen conveying pipe spare technical field.Be used for oxygen conveying pipe, to prevent the generation of fire and explosion accident.
Along with the particularly continuous development of metallurgical industry of industrial production, increasing to oxygen demand, many occasions be unable to do without pipeline and carry.Carrier pipe mainly is carbon steel pipe, aluminum pipe, stainless steel tube, in oxygen conveying pipe, and along with increasing of oxygen delivery pressure, the pipe friction aggravation, the temperature accumulation in case reach ignition point, will cause burning.In the oxygen conveying pipe, all do not have the back-fire relief device at present, a place catches fire, and rapidly spreads, and can cause that several kilometers oxygen channel is destroyed overnight at short notice, and its loss is very heavy.
The purpose of this utility model is to overcome the hidden danger that exists in the existing oxygen conveying pipe, provides a kind of making easy, easy to use, can stop the copper spark arrester of the place's fire spreading diffusion of catching fire in the oxygen therapy pipeline.
The technical solution of the utility model is: copper spark arrester is welded by copper pipe and steel pipe or copper pipe and ring flange.The material of copper pipe is red copper or brass, and they have conducts heat soon the characteristics of rapid heat dissipation.In case the somewhere catches fire in the oxygen therapy pipeline, flame reaches the copper pipe place, dispels the heat rapidly, lowers the temperature through copper pipe, is lower than ignition point, and burning is just extinguished automatically.Above-mentioned steel pipe is generally low carbon steel pipe, is convenient to welding; Ring flange can be a low-carbon steel material, also can be red copper or brass material.The structure of copper pipe is straight tube or bend pipe or three-way pipe or reduced pipe, to adapt to the needs of oxygen therapy pipeline attaching.
Simple in structure by the copper spark arrester that above scheme makes, make easily, in the oxygen therapy pipeline, be welded conveniently, can stop the diffusion that spreads at the place that catches fire, prevent the generation of fire and explosion accident.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Accompanying drawing is the structural representation of copper spark arrester.
Among this embodiment, copper spark arrester adopts special process to be welded by copper pipe 1 and steel pipe 2, and the copper pipe material is H
62Brass, its structure are the isometrical garden of through type pipe, and tube material is 20
#Mild steel.Or copper spark arrester is welded by copper pipe 1 and steel pipe 2 and copper ring flange 3 dishes, and copper pipe is H with the material of copper orchid method dish
62Brass, the material of steel pipe are 20
#Mild steel.During use, can select the copper spark arrester of different types according to the installation needs of oxygen therapy pipeline.
