As preferably, described seal ring is provided with conical surface near the side of link, and described link inner chamber is provided with the inner conical surface matched with the conical surface on seal ring.After straight-through seat and link are tightened, inner conical surface on link produces an impacting force to seal ring, transitional surface between the inner side surface of the annular groove on seal ring and crest and crest to otch is fitted completely, there is the sealing effect in 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, the port inner diameter of described seal ring near one end of link is greater than the external diameter of the port of corrugated flexible hose incision.Seal ring is avoided 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 and leak the smooth discharge of combustion gas, prevent the intrusion of harmful matter again, once corrugated flexible hose is damaged and cause gas leakage, then the combustion gas of leaking flows to the straight-through seat at two ends along the gas guide groove in plastic sheath, discharges from Leak hole.
As preferably, described link is pipe thread with the screw thread of other pipe fitting joints.The connection of convenience and other pipe fittings.
As preferably, the externally threaded afterbody that described straight-through seat is connected with link is provided with circular groove, is provided with O type circle in circular groove.When straight-through seat and link are tightened, O shape circle will be squeezed and produce sealing, can prevent on the one hand the intrusion of extraneous harmful matter, the combustion gas of Leakage prevention can leak from outside thread on the other hand, guarantee that leakage combustion gas can only be discharged from Leak hole.
As preferably, the eyelet that described clamping ring is separated by two halves forms.
After adopting above structure, fuel gas transmission stainless steel corrugated flexible hose of the present utility model leads directly to pipe fitting compared with prior art, have the following advantages: after straight-through seat and link are tightened, seal ring compresses by the inner conical surface of link inner chamber, transitional surface between the inner side surface of the annular groove on seal ring and crest and crest to otch is fitted completely, reach side seal and end face seal double sealing effect, inner conical surface simultaneously on link and the conical surface on seal ring are fitted completely, make very close to each otherly between link and seal ring to reach sealing effect, improve the sealing of whole parts, sealing effect is made to reach the optimum state, owing to not needing to carry out flat mouth process to corrugated flexible hose port, simply rational in infrastructure, be convenient to install.
