Groove occupies the 1/4 of the bulge loop, and the corresponding central angle of camber line is 45 ° where the two neighboring groove, when muff is heated
During deformation, the groove is capable of the internal stress of balance protection set body, strengthens the anti-pressure ability of protective case, while preventing protective case
Burst because deformation is excessive.
A kind of muff that the utility model is provided, the inwall that can be further arranged to the hollow body is provided with multiple
The reinforcement of spiral distribution, reinforcement can protect the hollow body, and spirally distribution can absorb a part of planted agent
Power, and hollow body can be made to possess certain elasticity, prevent hollow body from causing to burst because deformation is excessive.
A kind of muff that the utility model is provided, can be further arranged to the hollow body by various crystal fibres
Synthesis, fiber-like heat-barrier material is due to low cost, density is low, thermal conductivity factor is low, specific heat capacity is small, use easy to operate, heat-insulated effect
It is really good.
A kind of muff that the utility model is provided, the vertical section that can be further arranged to the hollow body is certainly introversive
Outer to include flexible silicon dioxide fibre layer, magnesium aluminate fibrage and continuous zirconia fiber layer successively, synthetic fibers not only retain
Original crystal fibre advantage of itself, and further enhancing the heat-proof quality of synthetic fibers, stability and heat resistance.
A kind of muff that the utility model is provided, can be further arranged to the flexible silicon dioxide fibre layer, aluminium
The thickness proportion of sour magnesium fibrage and continuous zirconia fiber layer three is 1:2:0.4.
In sum, the utility model is by the bulge loop structure outside hollow body, makes protective case in expanded by heating, convex
Ring structure balances internal stress, carries out a certain degree of contraction, makes protective case clamping pipe, it is to avoid protective case is excessive and de- because deforming
Fall or even burst, the utility model sound construction, anti-pressure ability is strong.
