Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: including inner tube 1, and inner tube 1 is the aluminum alloy component, 1 outer curved surface of inner tube bonds there is heat preservation 2, and heat preservation 2 is the cotton material component of heat preservation, 2 outer curved surfaces of heat preservation bond there is outer tube 3, and outer tube 3 is the stainless steel component, 3 outer curved surfaces of outer tube wind welding have steel wire 4, 3 outer curved surface welding in both ends of outer tube have go-between 5, and go-between 5 quantity has two, outer curved surface symmetric distribution in both ends of outer tube 3, inner tube 1, heat preservation 2, outer tube 3 and go-between 5 both sides terminal surface are on same vertical plane, go-between 5 outer terminal surface middle part has seted up ring channel 6, 6 inner walls of ring channel bond there is inflatable seal circle 7, and inflatable seal 7 telescopic part is hidden in the recess under the natural state, inflatable seal 7 is the silicon rubber component, inflatable seal 7 outside is fixed and is provided with charging connector 8, go-between 5 outer terminal surface side has seted up recess 9, and 8 outer curved surface laminating swing joint is at the recess 9 inner wall of go-between 5, run-through connecting hole 10 has been seted up outside go-through connecting hole 10 outside go-through, and connecting hole 10 quantity has six, it is with go-between 5 go-between rotational symmetric distribution outside to use the go-between 5.
The working principle is as follows: when the utility model is used, the through connection hole 10 is arranged outside the connection ring 5, the required connection pipeline or equipment can be connected to two sides of the utility model by using bolts, when the required connection pipeline or equipment is bolted to two sides of the utility model, the charging connector 8 is fixedly arranged outside the charging connector 7, air is injected into the charging connector 7, after air is injected into the charging connector 7, the charging connector 7 is expanded and deformed under the action of air pressure, the middle part of the charging connector 7 expands outwards towards the annular groove 6 arranged in the middle of the outer end surface of the connection ring 5, and is in close contact with the other sealing surface connected by the bolts, thereby achieving the sealing effect, when the sealing state needs to be relieved, high-pressure gas in the charging connector 7 is discharged through the charging connector 8, thereby the expansion part of the charging connector 7 automatically retracts into the groove 9 under the action of rubber elasticity and is separated from the sealing surface, when the inner pipe 1 is ventilated, when the inner pipe 1 is circulated with high-temperature or low-temperature gas, the required connection pipeline is subjected to temperature change, thereby the required connection pipeline is not consistent with the gap of the connection ring 5, or when the inner part is exposed to the sealing gap of the sealing ring, the sealing gap, the inner part is prevented from being expanded, thereby preventing the charging connector 7 from being effectively, the sealing effect of the charging connector 7, the sealing gap, thereby preventing the sealing effect of the sealing from being further caused by the sealing of the internal heat insulation of the internal heat-sealing device, and preventing the sealing of the sealing device, and preventing the sealing device, thereby preventing the sealing device from being effectively preventing the sealing gap of the sealing device from being exposed, and preventing the sealing device from being damaged by the sealing gap of the internal of the sealing device;
when simultaneously ventilating as inner tube 1, inner tube 1 is the aluminum alloy component, it is softer because of the aluminum alloy material, can not produce the spark when inner tube 1 meets the collision, thereby play the explosion-proof effect of physics, the heat preservation 2 that 1 outer curved surface of inner tube bonded is the cotton material component of heat preservation, and the heat preservation cotton is a high-efficient heat retaining material, and light in weight has, corrosion-resistant and syllable-dividing effect, thereby play the heat retaining effect of physics, outer tube 3 that 2 outer curved surfaces of heat preservation bonded is the stainless steel component simultaneously, and stainless steel has higher plasticity, toughness, mechanical strength and corrosion resistance, thereby play the effect of effective inside heat preservation 2 and inner tube 1 of protection, through 3 outer curved surface winding welded steel wires 4 of outer tube, can further strengthen the structural strength of outer tube 3, thereby further play the explosion-proof effect.
