Abstract
The utility model discloses a gas rubber tube being convenient to be bent, which comprises a tube body. The tube body comprises a first tube body and a second tube body, and the first tube body and the second tube body are connected through a corrugated tube. The corrugated tube can be made of metal material, and two ends of the corrugated tube are nested and matched with the first tube body and the second tube body. The gas rubber tube utilizes the corrugated tube connected at the middle part of the tube body for alleviating stress centralization, so that the service life of the gas rubber tube is prolonged.
Description
Technical field
The utility model relates to a kind of sebific duct, relates in particular to a kind of pneumatic hose that is used for delivery of fuel gas.
Background technique
The sebific duct that is used for delivery of fuel gas must can tolerate bigger pressure, and this just need add reinforcing fiber in pliable and tough tube wall.The body of pneumatic hose is generally three-decker in the prior art, is respectively inner glue layer, reinforcing fiber layer and outer glue-line from inside to outside, and wherein inner glue layer, outer glue-line can adopt materials such as modified rubber, and the reinforcing fiber layer can adopt nylon or glass fibre etc.For the bulk strength and the withstand voltage properties that keep sebific duct, the reinforcing fiber layer generally is interwoven by warp and parallel.
Along with the popularization of hybrid vehicle, be used to carry the consumption of combustion gas sebific duct of hybrid vehicle fuel also increasing, the combustion gas sebific duct often needs bending in use, and stress ratio is more concentrated at the position of bending, uses easily cracking or damages for a long time.
The model utility content
The utility model provides a kind of combustion gas sebific duct, has improved the intensity of bending part by bellows, and concentrating of relieve stresses prolonged the working life of combustion gas sebific duct.
A kind of combustion gas sebific duct of being convenient to bending comprises body, and described body comprises first body and second body, connects by bellows between first body and second body.
Bellows can be protected the crooked position of body, the concentrating of relieve stresses.Bellows can adopt metal material, and the two ends of bellows cooperate with second body is nested with first body.Can adopt prior art itself with regard to body.
The two ends of described body are equipped with metal joint.Described metal joint one end has flanging, and the other end is enclosed within on the pipe end, and the flanging position is with nut.Be enclosed within the end on the pipe end and the termination outer wall interference fit of body, nut can be connected with other pipe fittings fast.
The bellows that the utilization of the utility model combustion gas sebific duct is connected in the middle part of the body has been alleviated concentrating of stress, has prolonged the working life of combustion gas sebific duct.
Description of drawings
Fig. 1 is the structural representation of the utility model combustion gas sebific duct.
Embodiment
Referring to Fig. 1, a kind of combustion gas sebific duct of being convenient to bending of the utility model comprises body, and body comprises between first body 2 and second body, 3, the first bodys 2 and second body 3 and connecting by bellows 1.
Bellows 1 can be protected the crooked position of body, the concentrating of relieve stresses.Bellows 1 adopts metal material, and the two ends of bellows 1 cooperate with the termination of second body 3 is nested with first body 2.
The two ends of body are equipped with metal joint.Metal joint one end has flanging 5, and the other end is enclosed within on the pipe end, and the flanging place is with nut 4, and nut 4 can be connected with other pipe fittings fast.
The bellows that the utilization of the utility model combustion gas sebific duct is connected in the middle part of the body has been alleviated concentrating of stress, has prolonged the working life of combustion gas sebific duct.
