As preferably, described seal ring is provided with conical surface near a side of link, described link inner chamber be provided with seal ring on the inner conical surface that matches of conical surface.After straight-through seat is tightened with link, inner conical surface on link produces an impacting force to seal ring, the inner side surface of the annular groove on seal ring and crest and crest to the transitional surface between otch are fitted completely, there is the sealing effect on the both direction of side seal and end face seal, improve the sealing of whole parts, make sealing effect reach the optimum state.
As preferably, described seal ring is greater than the external diameter of the port of corrugated flexible hose incision near the port internal diameter of one end of link.Avoid seal ring to be hurt by the port of corrugated flexible hose incision tightening in deformation process.
As preferably, described straight-through seat is provided with Leak hole, and aperture is 0.5-1.5mm.Can take into account the smooth discharge of leaking combustion gas, prevent again the intrusion of harmful matter, cause gas leakage, the combustion gas of leaking to flow to the straight-through seat at two ends along the gas guide groove in plastic sheath once corrugated flexible hose is damaged, discharge from Leak hole.
As preferably, on described link, be pipe thread with the screw thread of other pipe fitting joints.Convenience is connected with other pipe fittings.
As preferably, the upper externally threaded afterbody being connected with link of described straight-through seat is provided with circular groove, is provided with O type circle in circular groove.In the time that straight-through seat is tightened with link, O shape circle will be squeezed and produce sealing, and one side can prevent the intrusion of extraneous harmful matter, and combustion gas that on the other hand can Leakage prevention leaks from outside thread, guarantees to leak combustion gas and can only discharge from Leak hole.
As preferably, the eyelet that described clamping ring is separated by two halves forms.
Adopt after above structure, combustion gas of the present invention is carried and is used the straight-through pipe fitting of stainless steel ripple flexible pipe compared with prior art, have the following advantages: after straight-through seat is tightened with link, the inner conical surface of link inner chamber compresses seal ring, the inner side surface of the annular groove on seal ring and crest and crest to the transitional surface between otch are fitted completely, reach side seal and end face seal double seal effect, inner conical surface on link and the conical surface on seal ring are fitted completely simultaneously, make the sealing effect that reaches very close to each other between link and seal ring, improve the sealing of whole parts, make sealing effect reach the optimum state, owing to not needing that corrugated flexible hose port is carried out to flat mouth processing, rational in infrastructure simple, be convenient to install.
