Embodiment
The present invention includes: hose body 1, protective layer 2, sleeve 3, joint 4, flexible supporting frames 5 and oversheath 6.
In the present invention, available protecting is realized for hose body 1 and joint 4.In order to block joint 4 and sleeve 3 radiation-absorbing heat, the length of oversheath 6 exceeds two ends sleeve 3 olo.
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment 1: as shown in Figure 1; hose body 1 two ends are jointing 4 respectively; two joints (4) are connected by sleeve (3) with hose body (1); overcoat protective layer 2 between two sleeves 3; at protective layer 2 overcoat flexible supporting frames 5, at flexible supporting frames 5 outer wrapping oversheath 6.
In aforementioned, outside sleeve 3, be set with location slip ring 7, location slip ring 7 outer rim apical grafting oversheath 6 inwall.
In aforementioned, flexible supporting frames 5 is spring, and adopt existing general material and technique to make, sufficiently long straight end is left at two ends, and carries out corresponding heat treatment, is conveniently wrapped in hose coupling neck; Flexible supporting frames 5 supports oversheath 6, and ensures that flexible pipe can bend smoothly.
In aforementioned, at the location slip ring 7 external stability clip 8 of oversheath 6.Oversheath 6 adds stainless steel metal net for fire-proof covering, fiberglass flame or glass fibre.Oversheath 6 is as the exterior cover sheets set up, and oversheath 6 cuts off radiation heat and stops hot splash.Flexible supporting frames 5 connects location slip ring 7.Location slip ring 7 adopts the material such as steel, rubber, adopt casting, die casting, forging or machining method process.Location slip ring 7 ensures that flexible supporting frames 5 is coaxial with hose body 1, slide on sleeve 3 when hose body 1 bends compensation protective layer 2 and hose body 1 length change inconsistent, leave air communication channel and ensure air circulation.
In aforementioned, oversheath 6 and flexible supporting frames 5 are fixed on the slip ring of location by clip 8.
Heat transmission in the present embodiment and balance working principle comprise, as shown in Figure 4, when having thermal source, and protective layer 2 radiation-absorbing heat, temperature raises, and original thermal equilibrium is broken; Now hose body 1 absorbs the thermal radiation of protective layer 2; namely main thermaltransmission mode; due to the cross-ventilation in gap; when the temperature of hose body 1 is a little more than stable back to inclining to during the air temperature of heat source side; the factors such as the temperature of this temperature because of thermal source, the distance from thermal source are different, and each part temperatures of rubber hose assembly reaches dynamic balancing.And as shown in Figure 5, when thermal source is cancelled, protective layer and the outside radiations heat energy of flexible pipe, the cross-ventilation in annular space accelerates the surface cool of hose body 1, and hose body 1 temperature declines very fast, keeps balance when reaching ambient temperature.
Embodiment 2: as shown in Figure 6, when radiation heat is very strong, for reducing the heat conduction of joint 4 absorption on the hose body 1 of rubber, strengthen the internal diameter of oversheath 6 and flexible supporting frames 5, lengthen the length of oversheath 6, even exceed the overall length of rubber hose assembly, and make it prolongation and be wrapped in outside two end connectors 4, heat transfer distance can be extended.Oversheath 6 length is greater than two end connector 4 exterior edge face spacing, the maximum outside diameter of joint that oversheath 6 and flexible supporting frames 5 internal diameter are greater than joint 4 and are attached thereto.During mounting or dismounting rubber hose assembly, can axial compression flexible supporting frames 5, joint 4 is exposed at two ends.
Embodiment 3: as shown in Figure 7; Namely as in embodiment 2, also can the simultaneously neck of lengthening joint 4 and the length of oversheath 6.
Above three examples can select optimum scheme according to the concrete condition of radiations heat energy and installation conditions.
In the present invention, hose body 1 is flexible, and the motion of pipeline trend and equipment all needs rubber hose assembly to bend, and flexible supporting frames 5 bending force of spring structure is little, radial deformation is little, the problem that during the movable structure energy compensated bend in two ends, oversheath 6 is inconsistent with hose body 1 length change; The joint 4 neck winding structure at flexible supporting frames 5 two ends, can when length compensation is inadequate tensile elasticity supporting frame 5, ensure that sleeve 3 position be wrapped in oversheath 6 is protected, can not directly radiation-absorbing be warm.
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, dress rubber hose assembly one end connector also connects with sleeve 3; Dress internal protection layer 2 is also fixing, can omit this structure during splash as hot without molten steel, slag etc. in Environmental Conditions; Dress two pieces location slip ring 7, oversheath 6 is enclosed within flexible supporting frames 5 and is also set to together on rubber hose assembly, dress rubber hose assembly the other end joint 4 also connects with sleeve 3, slip ring 7 position, adjustment location, the hoop 8 that is installed fixes oversheath 6 and flexible supporting frames 5, is directly held at flexible supporting frames 5 two ends and is wound into hose coupling 4 neck; When the internal diameter of flexible supporting frames 5 is greater than rubber hose assembly maximum outside diameter, the location slip ring 7 at two ends is contained on hose body 1, be enclosed within by oversheath 6 on flexible supporting frames 5 and be also set to together on rubber hose assembly, slip ring 7 position, adjustment location, the hoop 8 that is installed fixes oversheath 6 and flexible supporting frames 5.
In the present invention, flexible supporting frames 5 is increased between flexible pipe 1 and oversheath 6, this flexible supporting frames 5 internal diameter is greater than the external diameter of hose body 1, flexible supporting frames 5 and form annular space between oversheath 6 and rubber hose assembly, when using under high temperature heat radiation environment, the heat that oversheath 6 absorbs is not directly passed to hose body 1 by heat conducting, its radiation and air conduction can only be passed through, the heat that these two kinds of thermaltransmission mode hose bodies 1 absorb is limited, be far smaller than protective layer 2 directly heat transfer time the heat that absorbs; And the cross-ventilation on thermal source side is fast, also accelerates the convection current of air in annular space, so also can take away the heat of hose surface, play cooling action.The utilization of flexible supporting frames 5 can not destroy the flexibility of hose body 1, hose body 1 can in its minimum bending radius allowed band free bend.The effective length of lengthened hose oversheath 6, avoids hose coupling 4 radiation-absorbing heat.When external heat source is cancelled, the heat that protective layer and flexible pipe absorb swiftly passes through radiation and cross-ventilated method transmission is fallen, and the temperature of flexible pipe reduces very soon, thus extends the working life of rubber hose assembly.
The present invention on the rubber hose assembly at steel works billet continuous casting fan-shaped section and Iron Works clay gun position experiment on probation, its working life than long 3 times of existing guard method, and decreases the probability of flexible pipe random failure.Like this, decrease replacing number of times and the spare parts consumption of spare part, reduce the input of manpower and financial resources, stop the accident of hoses leak, booster initiation.Reduce the cost of user, enhance competitiveness.
