Abstract
The utility model discloses a gas rubber tube capable of increasing strength of a bending part, which comprises a tube body. A spring is wound on the outer wall of the tube body. The spring is in a form of a helical line and can protect the bending part of the tube body. In the gas rubber tube, the spring sheathed outside the tube body and in the form of the helical line is adopted for improving the strength of the bending part of the tube body; therefore, 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 stiffening element, has prolonged the working life of combustion gas sebific duct.
A kind of combustion gas sebific duct that improves bending part intensity comprises body, and described tube wall is wound with spring.Spring is the helix form, can protect the crooked position of body.
The two ends of described body are equipped with metal joint, and two terminations of described spring are connected on the corresponding metal joint.
Described metal joint one end has flanging, and the other end is the corrugated sleeve pipe that is enclosed within on the pipe end, and an end that has flanging is with nut.The termination outer wall interference fit of corrugated sleeve pipe and body, the corrugated sleeve pipe has some roads contractile ring radially, outer wall that can the banding pipe end.Nut can be connected with other pipe fittings fast.Can adopt prior art itself with regard to body.
Fixedly connected with the inwall of corrugated sleeve pipe in the termination of described spring.Can be Placements such as welding.
The spring that the utilization of the utility model combustion gas sebific duct is enclosed within the outer helix form of body has improved the intensity of body bending part, 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 that improves bending part intensity of the utility model comprises body 1, and body 1 outer wall is wound with the spring 2 of helix form.
The two ends of body 1 are equipped with metal joint, and metal joint one end has flanging 5, and the other end is the corrugated sleeve pipe 3 that is enclosed within on the pipe end, and an end that has flanging 5 is with nut 4.
The termination outer wall interference fit of corrugated sleeve pipe 3 and body 1, corrugated sleeve pipe 3 has some roads contractile ring radially, outer wall that can the banding pipe end, nut 4 is convenient to be connected with other pipe fittings fast.Fixedlying connected with the inwall of corrugated sleeve pipe 3 in the termination of spring 2, can be Placements such as welding.
The spring that the utilization of the utility model combustion gas sebific duct is enclosed within the outer helix form of body has improved the intensity of body bending part, has prolonged the working life of combustion gas sebific duct.
Claims (4)
1. a combustion gas sebific duct that improves bending part intensity comprises body, it is characterized in that described tube wall is wound with spring.
2. the combustion gas sebific duct of raising as claimed in claim 1 bending part intensity is characterized in that the two ends of described body are equipped with metal joint, and two terminations of described spring are connected on the corresponding metal joint.
