Abstract
The utility model discloses a teflon-lined compound metal hose which comprises a small flange, a loose flange, a connecting pipe, sheaths, a net sleeve, a bellows and a flexible metal liner tube. Two ends of the bellows are fixedly connected with the connecting pipe, two ends of the connecting pipe are fixedly connected with the small flange, the loose flange is sleeved on an outer wall of the connecting pipe, the net sleeve is externally sleeved on an outer wall of the bellows, the sheaths are externally sleeved at two ends of the net sleeve and jointly fixedly connected to the outer wall of the connecting pipe, the flexible metal liner tube is sleeved in the bellows, two ends of the flexible metal liner tube are in sealed connection with the end face of the connecting pipe, a teflon composite layer is arranged on an inner wall of the flexible metal liner tube. The teflon-lined compound metal hose is simple in structure and easy to achieve, pressure loss in the transportation process is small, abrasion is small in the using process, and the service life of the metal hose is long.
Description
Technical field
The utility model relates to a kind of metallic hose, and specifically, the utility model relates to a kind of metallic hose take bellows as main component.
Background technique
Steel mill's transferring oxygen of using converter oxygen lance pipe adopts metallic hose basically, and the metallic hose of prior art is carried in bellows take bellows, adapter, net as main member, oxygen.Because the characteristics such as that metallic hose has is flexible, lightweight, bearing capacity is high, be difficult for aging and high temperature resistant, the oxygen rifle that has solved the well pneumatic steelmaking problem that is flexible coupling, but the metallic hose of prior art is Shortcomings also, mainly be longer for the length of the metallic hose of steel mill's transferring oxygen of using converter oxygen lance, when oxygen passes through from bellows, because the waveform configuration of bellows, oxygen moves in the cross section that constantly changes, the pressure loss is larger in carrying the way, the oxygen pressure in the time of can not guaranteeing to use; On the other hand, the bellows wall thickness is thinner, and long-term the use easily galled, so that the working life of metallic hose is shorter.
Summary of the invention
The utility model is for the deficiencies in the prior art, propose a kind of simple in structure, in the using process wearing and tearing less, and the little lining tetrafluoro composite metal flexible pipe of transferring oxygen of using converter oxygen lance course pressure loss, the working life of this metallic hose is longer.
The utility model is achieved through the following technical solutions technical goal.
Lining tetrafluoro composite metal flexible pipe, it comprises little flange, lap joint flange, adapter, sheath, net and bellows; Described bellows two ends are fixedly connected with adapter, take over two ends and are fixedly connected with little flange, and the lap joint flange pine is enclosed within takes on the outer wall; Described net is enclosed within outward on the bellows outer wall, and sheath is enclosed within the net two ends outward, and jointly is fixedly connected on the adapter outer wall; Its improvements are: also comprise the flexible metal bushing pipe, described flexible metal liner sleeve is combined in the bellows, and its two ends are connected with the adapter end face seal; Inwall at the flexible metal bushing pipe is provided with the teflon composite bed.
The utility model compared with prior art has following good effect:
1. simple in structure, be easy to realize.
2. the flexible metal bushing pipe is set, and oxygen is carried in the bushing pipe of flexible metal, because flexible metal bushing pipe inner hole section is basically identical, so that the pressure loss of oxygen in course of conveying is very little, and the oxygen pressure when being easy to guarantee to use.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the I partial structurtes enlarged diagram among Fig. 1.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments for the below.
Lining tetrafluoro composite metal flexible pipe shown in the accompanying drawing 1, it comprises little flange 1, lap joint flange 2, adapter 3, sheath 4, net 5, bellows 6 and flexible metal bushing pipe 7, bellows 6 two ends are fixedly connected with takes over 3, take over 3 two ends and be fixedly connected with little flange 1, lap joint flange 2 pines are enclosed within takes on 3 outer walls; Net 5 outer being enclosed within on bellows 6 outer walls are enclosed within net 5 two ends outside the sheath 4, and jointly are fixedly connected on adapter 3 outer walls.Flexible metal bushing pipe 7 is linked in the bellows 6, its two ends are connected with adapter 3 end face seals, and oxygen is in the 7 interior conveyings of flexible metal bushing pipe, because bushing pipe 7 inner hole sections in flexible metal are basically identical, so that the pressure loss of oxygen in course of conveying is very little, the oxygen pressure when being easy to guarantee to use.Inwall at flexible metal bushing pipe 7 is provided with teflon composite bed 8, can so that metallic hose in use, the wearing and tearing of bushing pipe 7 seldom effectively prolong the working life of metallic hose.
