Fig. 2 is a schematic structural view of a bellows.
Detailed Description
Embodiments of the present utility model will be described in detail below with reference to the drawings.
As shown in fig. 1 and 2, the corrugated pipe comprises a corrugated pipe body 1, a straight pipe section 12, a sealing convex edge, a clamping sleeve 2, a net sleeve 3, a fastening sleeve 4, a clamping ring 5, a loose joint nut 6, an internal and external threaded joint 7 and a sealing gasket 8.
A threaded connection explosion-proof hose is shown in figure 1, is mainly suitable for explosive dangerous environments such as petroleum extraction, storage, chemical industry, medicine, textile, printing and dyeing, military industry and military facilities, and the like, and structurally comprises a corrugated pipe 1, a cutting sleeve 2, a net sleeve 3 and the like.
The corrugated pipe 1 is a stainless steel corrugated pipe, is mainly used on an air conditioner pipeline in the embodiment, and has the effects of silencing, damping, buffering internal pressure fluctuation and the like, one end of the corrugated pipe 1 is provided with a straight section pipe 11 shown in fig. 2, and a sleeved clamping sleeve 2 is arranged outside the straight section pipe; the net cover 3 is a stainless steel net covered outside the corrugated pipe 1, and plays roles in protecting the corrugated pipe 1 from bearing high pressure, preventing explosion, prolonging the service life of the corrugated pipe and the like.
The end opening of the net sleeve 3 extends out of the clamping sleeve 2, and is fixed by the fastening sleeve 4 sleeved outside the clamping sleeve through deformation and compaction, and the clamping sleeve 2 also plays a role in protecting the thin-wall pipe of the straight pipe 11 and reversely compacting the net sleeve 3.
