The present invention realizes effectively protecting for hose body 1 and joint 4.Radiant heat is absorbed in order to block joint 4 and sleeve 3, The length of oversheath 6 exceeds two ends sleeve 3 olo.
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: as shown in Figure 1, hose body 1 two ends jointing 4, two joints (4) and hose body (1) respectively lead to Cross sleeve (3) to connect, overcoat protective layer 2 between two sleeves 3, at protective layer 2 overcoat flexible supporting frames 5, prop up in elasticity Support 5 outer wrapping oversheath 6.
In aforementioned, outside sleeve 3, it be set with location slip ring 7, position slip ring 7 outer rim apical grafting oversheath 6 inwall.
In aforementioned, flexible supporting frames 5 is spring, uses existing general material and technique to make, and two ends are left sufficiently long Straight end, and be heat-treated accordingly, conveniently it is wrapped in hose coupling neck;Flexible supporting frames 5 supports oversheath 6, and Ensure that flexible pipe can bend smoothly.
In aforementioned, at the location slip ring 7 external stability clip 8 of oversheath 6.Oversheath 6 is fireproof covering, fire prevention Glass fibre or glass fibre add stainless steel metal net.Oversheath 6 is as the exterior cover sheets set up, oversheath 6 Cut off radiant heat and stop hot splash.Flexible supporting frames 5 connects location slip ring 7.Location slip ring 7 use steel, The materials such as rubber, use the method processing of casting, die casting, forging or machining.Location slip ring 7 ensures elasticity Bracing frame 5 is coaxial with hose body 1, and sliding on sleeve 3 when hose body 1 bends compensates protective layer 2 and hose body 1 Length change is inconsistent, leave air communication channel ensures air circulation.
In aforementioned, oversheath 6 and flexible supporting frames 5 are fixed on the slip ring of location by clip 8.
Heat transmission and balance operation principle in the present embodiment include, as shown in Figure 4, when having thermal source, and protective layer 2 absorb radiant heat, and temperature raises, and original thermal balance is broken;Now hose body 1 absorbs the hot spoke of protective layer 2 Penetrate, main thermaltransmission mode, due to the cross-ventilation in gap, when the temperature of hose body 1 is slightly above back to heat Inclining to stable during the air themperature of source, the factor such as this temperature temperature because of thermal source, the distance from thermal source is different, Each part temperatures of rubber hose assembly reaches dynamic balancing.And as shown in Figure 5, when thermal source is cancelled, protective layer and flexible pipe Outwards radiations heat energy, the cross-ventilation in annular gap accelerates the surface cooling of hose body 1, and hose body 1 temperature declines Quickly, reach to keep balance during environment temperature.
Embodiment 2: as shown in Figure 6, when radiant heat is the strongest, the heat absorbed for reducing joint 4 is transmitted to On the hose body 1 of rubber, strengthen oversheath 6 and the internal diameter of flexible supporting frames 5, lengthen the length of oversheath 6, very To exceeding the overall length of rubber hose assembly, and it is allowed to prolongation and is wrapped in outside two end connectors 4, heat transfer distance can be extended. Oversheath 6 length is more than two end connector 4 outer face spacing, oversheath 6 and flexible supporting frames 5 internal diameter more than joint 4 Maximum outside diameter with the joint being attached thereto.During mounting or dismounting rubber hose assembly, flexible supporting frames 5, two ends can be compressed axially Expose joint 4.
Embodiment 3: as shown in Figure 7;I.e. as in embodiment 2, it is also possible to the neck of lengthening joint 4 is with outer simultaneously The length of sheath 6.
Above three examples can select preferred plan according to the concrete condition of radiations heat energy and mounting condition.
In the present invention, hose body 1 is flexible, and the motion of pipeline trend and equipment is required for rubber hose assembly bending, Flexible supporting frames 5 bending force of spring structure is little, and radial deformation is little, during the movable structure energy compensated bend in two ends outside The problem that sheath 6 is inconsistent with the change of hose body 1 length;The joint 4 neck winding arrangement at flexible supporting frames 5 two ends, Can when length compensation is inadequate tensile elasticity bracing frame 5, it is ensured that sleeve 3 position being wrapped in oversheath 6 obtains Protection, will not directly absorb radiant heat.
In the present embodiment, when the internal diameter of flexible supporting frames 5 is less than the maximum outside diameter of rubber hose assembly joint 4, fill soft Pipe sub-assembly one end connector also connects with sleeve 3;Dress internal protection layer 2 is also fixed, as used environment without molten steel, steel This structure can be omitted during the hot splash such as slag;Dress two pieces location slip ring 7, is enclosed within flexible supporting frames 5 by oversheath 6 Going up and be set to together on rubber hose assembly, dress rubber hose assembly other end joint 4 also connects with sleeve 3, adjusts location Slip ring 7 position, the hoop 8 that is installed is fixed oversheath 6 and flexible supporting frames 5, flexible supporting frames 5 two ends straight end is twined Around hose coupling 4 neck;When the internal diameter of flexible supporting frames 5 is more than rubber hose assembly maximum outside diameter, by two ends Location slip ring 7 is contained on hose body 1, and oversheath 6 is enclosed within flexible supporting frames 5 and is set to together flexible pipe combination On part, adjusting slip ring 7 position, location, the hoop 8 that is installed fixes oversheath 6 and flexible supporting frames 5.
In the present invention, increasing flexible supporting frames 5 between flexible pipe 1 and oversheath 6, this flexible supporting frames 5 internal diameter is more than The external diameter of hose body 1, forms annular gap, in high-temperature hot between flexible supporting frames 5 and oversheath 6 and rubber hose assembly When using under radiation environment, the heat that oversheath 6 absorbs can not be directly passed to hose body 1, only by heat transfer Can be by its radiation and air transmitted, the heat that both thermaltransmission mode hose bodies 1 absorb is limited, the least The heat absorbed when protective layer 2 direct heat transfer;And the cross-ventilation on thermal source side is fast, also accelerates annular gap The convection current of middle air, the most also can take away the heat of hose surface, play cooling effect.The utilization of flexible supporting frames 5 The flexibility of hose body 1 will not be destroyed, hose body 1 can in its minimum bending radius allowed band free bend.Add The effective length of long soft-pipe oversheath 6, it is to avoid hose coupling 4 absorbs radiant heat.When external heat source is cancelled, protection The heat that layer and flexible pipe absorb swiftly passes through radiation and the transmission of cross-ventilated method is fallen, and the temperature of flexible pipe quickly reduces, Thus extend the service life of rubber hose assembly.
Present invention experiment examination on the rubber hose assembly at steel mill billet continuous casting fan-shaped section and Iron Works clay gun position With, its service life is longer than existing guard method 3 times, and decreases the probability of flexible pipe random failure.So, Decrease replacing number of times and the spare parts consumption of spare part, reduce the input of manpower and financial resources, stop hoses leak, quick-fried The accident that pipe causes.Reduce the cost of user, improve competitiveness.
