Vent plug is provided on the cutting ferrule locking type gas nozzle of described aluminium bracket one end.
The copper pipe is brass tube.
The aluminium bracket selects 6061-T6 aluminium alloy to be made, and the bonding plane two sides of aluminium bracket have strengthening wing.
The cutting ferrule locking type gas nozzle is connect with the gas nozzle installation set being arranged in aluminium bracket mounting-positioning holes, copper pipe end
In portion's insertion gas nozzle installation set and seal.
Compared with prior art, the invention has the following advantages:
EMU pantograph pan of the invention, the whole carbon item of pure charcoal carbon item, using roasting work after isostatic pressing
Skill, gained carbon performance have excellent isotropism, and carbon performance is more stable and function admirable.Pure charcoal carbon slipper with it is similar
Carbon slipper is compared, and has many advantages, such as that simple process, air flue form are safe and reliable, abrasion are low, light-weight.In addition, of the present invention
Pressure-relief vent, by after slotting copper pipe carry out bending after, be inserted into aluminium bracket mounting-positioning holes in cutting ferrule locking type gas nozzle, through cutting ferrule
Copper pipe locking locking is formed.Therefore the substitute that the more existing copper pipe of pressure-relief vent form of the invention and gas nozzle are welded
Road is more reliable, and preparation process is more simple, and air-tightness is more preferable.
Further, bonding plane two sides on aluminium bracket of the present invention, design high 2mm, bottom width 1.5mm, the reinforcement of top width 1mm
The wing, this structure can increase the bond area of carbon item Yu aluminium bracket, obtain more structurally sound adhesive property, guarantee carbon slipper globality
It can be more excellent, stable, reliable.
Further, carbon item relies on cupric powder conductive adhesive to solidify through Nian Jie with aluminium tray chamber, remaining spare part, fastener installation
To general assembly drawing specified position, copper pipe and gas nozzle welding procedure are removed, process flow is shortened, while performance is relatively reliable.
