Description
Technical field
This utility model relates to joint technique field, is specifically related to a kind of combustion gas Special loose joint head.
Background technology
Along with popularizing of the combustion gas such as natural gas, gas-cooker is more and more applied, the connection flexible pipe of air inlet
And mostly needing gas kitchen pipe joint be connected and seal between the air inlet of gas kitchen ranges, existing sealing ring is many
Being made up of rubber, rubber seal can occur as face checking is hardening after using a period of time, and retractility is deteriorated
Etc. catabiosis, affect the use of gas pipeline, and cause the main cause of catabiosis to have oxidation, illumination
The reasons such as slabbing, moisture attack, mechanical stress and other such as radiation, rubber seal great majority are all
Using under stress state, stress has significant impact to the chemical reaction velocity of rubber, due to rubber
Structure and the inhomogeneities of stress distribution thereof, in standing deformation fatigue process, stress will heavy damage rubber
The molecular structure of glue, makes macromole rupture, and generates free radical, causes the oxidative chain reactions of rubber macromolecule,
Cause ageing of rubber, it is impossible to use, therefore, should reduce when using rubber sealing ring as far as possible or disperse
Pressure size suffered by sealing ring, to reduce the stress within rubber, and in current gas kitchen pipe joint, set
Loose joint sleeve on joint is typically made up of the material such as copper or rustless steel, and deformability is far smaller than and is embedded at it
Internal rubber seal, the most just makes the pressure suffered by rubber seal be largely converted into self
Stress, if changing into loose joint sleeve being made up of the preferable material of retractility, make if any plastics, then can be big
The big sealing reducing loose joint sleeve, also reduces corrosion-resistant, the resistance to elevated temperatures of gas kitchen pipe joint, therefore,
Need a kind of new, do not change loose joint sleeve material and can reduce again the gas kitchen pipe joint structure of sealing ring stress.
