Abstract
The utility model provides a water cooling fire resistant hose assembly, comprising a hose body and hose connectors arranged on both ends of the hose. The hose assembly is characterized in that the hose body is provided outside with a water cooling pipe covered by a protective sleeve, and both ends of the water cooling pipe are provided with a water inlet and a water outlet. The water cooling fire resistant hose assembly has the advantages of low production cost, simple structure, quick production, convenient use and easy maintenance, and can effectively make the fire resistant and heat radiating protection on hose heads and hose connectors; compared with the inside glassfiber and outside silicone rubber hose, the water cooling fire resistant hose assembly is greatly improved in the fire resistant and heat radiating protection; under the condition of high temperature, and in places near open fire and thermal sources, the hose and the connectors can be safely used for a long time; in a fire accident, the hose assembly is not broken or fallen off for a long time; moreover, the operation of connecting hoses is easy.
Description
Technical field
The utility model belongs to and is applied near infrared source or inflammable high temperature, the hydraulic transmission equipment of hyperbaric environment, fire-resistant heat-resisting radiation technical field of hoses as equipment such as the steel-making of the control platform of oil drilling, metallurgy industry, ironmaking, continuous casting, hot rolling mills is specifically related to a kind of fire-resistant hose assembly of water-cooled of water-cooled heat-proof device in addition that has.
Background technique
At present, known hose assembly comprises: flexible pipe is connected with metal.Flexible pipe is main material with rubber, plastic cement, common product of rubber and plastic heat-resisting about 100 degrees centigrade, the heat resisting temperature of fluorine silica gel goods about 260 degree, but cost an arm and a leg.Now, the refractory heat-insulating device of flexible pipe is that the flexible pipe outside adds fireproof paint, thermal-protective coating and metal knitted net, is used for the heat-insulating, fire-preventing of flexible pipe.These measures have great importance for the fire-proof and thermal-insulation of body., this kind method is in the environment with infrared source or naked light, and life cycle is very short, that is to say that its refractory nature is restricted.For example, the pendulum of smelting industry caster cuts mouth and ingress, and flexible pipe is very near apart from the distance of steel billet, its radiation temperature reaches more than 400 ℃, if prevent fires by adding heat-shielding net, then significantly shortened the life-span of flexible pipe, increased the risk of seepage and explosion.
The flexible pipe protection sheath that also has a kind of interior fine outer glue at present, because the outside is for mostly being rubber materials such as silica gel, can only in being no more than 250 degrees centigrade environment, radiation temperature use, in case and breaking out of fire the time, or in naked light, the fire performance of this type of flexible pipe is also more limited, and therefore the application of fine product is subjected to certain restriction in the outer glue.And at present the heat-shielding net selected for use of refractory heat-insulating pipe is based on asbestos, and asbestos contain lead, and after flexible pipe was scrapped, these leaded asbestos gauges were to the harmful effect of person health and very serious to the pollution of environment.
The model utility content
The purpose of this utility model provides a kind of simple in structure, makes fast, and is easy to use, with low cost, and the fire-resistant hose assembly of the water-cooled that flexible pipe is used safely in hot environment for a long time.Overcome the not anti-long term high temperature radiation of existing hose assembly, cause the deficiency of seepage and explosion easily, improve the safe in utilization and working life of high temperature occasion and nearly fire environment bottom hose, reduce the pollution of heat-shielding net environment.
For achieving the above object, the technical solution adopted in the utility model is as follows:
The fire-resistant hose assembly of a kind of water-cooled comprises the pipe joint at hose body and flexible pipe two ends it is characterized in that described hose body is provided with water cooling tube outward that this water cooling tube is a metal sleeve, and by the sheath parcel, the water cooling tube two ends are provided with entery and delivery port outward.
Described hose body is provided with the double braid covering assembling structure outward from inside to outside, and its first layer is the outer metal sleeve layer of hose body, and described sheath is the second layer, and described sheath is to be sleeved on the outer metal knitted stratum reticulare of water cooling tube.
Described metal sleeve has the property of subduing, and the pipe joint at described hose body, metal sleeve and sheath and flexible pipe two ends is connected and fixed.
Described metal sleeve two ends are connected with the pipe joint at flexible pipe two ends and seal, and form airtight water cooled pipeline.
Described water cooling tube two ends are provided with the entery and delivery port that the entery and delivery port joint forms water cooling tube, and described water intake joint and water outlet joint lay respectively at outside the sheath at the fire-resistant flexible pipe of described water-cooled two ends.
Described water cooling tube is a metal sleeve, and described pipe joint is a metal joint, and described hose body, water cooling tube and sheath are formed the hose assembly that can subdue structure.
The fire-resistant hose assembly of this water-cooled is by putting water cooling tube in the hose overcoat installing; reduce the inside and outside heating temperature of flexible pipe; the overall of this water-cooled fire-proofing is tube-in-tube structure; include the pipe joint connection part at hose body and two ends; outside suit water cooling tube, water cooling tube is provided with sheath outward water cooling tube and flexible pipe is protected.When the fire-resistant hose assembly of this water-cooled uses, the pipe joint of flexible pipe is connected with equipment, the water intake joint at water cooling tube two ends is connected extraneous cooling water respectively with the water outlet joint, forms the circulating water pipeline that end water inlet one brings out water, reduces the temperature of outer protective sleeve and internal layer flexible pipe.The fire-resistant hose assembly of this water-cooled is not only protected hose body; and can effectively protect the tube head and the pipe joint joint of flexible pipe; make the ambient temperature of inherent flexible pipe be controlled at a lower state all the time; avoided thermal source or naked light directly to the baking of inherent flexible pipe; thereby guarantee the safe handling of the fire-resistant hose assembly of water-cooled, prolong working life.
After the fire-resistant flexible pipe assembling of this water-cooled is finished, can at first respectively inherent flexible pipe and water cooled pipeline be carried out fluid feeding test, to have determined whether seepage.The water cooling tube of the fire-resistant hose assembly of this water-cooled and restrictive coating all are to subdue structure; do not influence the pliability of flexible pipe; and include the protective gear of heat-shielding net than the braided steel wire sheath; has better thermal insulation; the flexible pipe that more effective protection is inherent, and have corrosion protection, the advantage of antistatic, high abrasion; and good bending property, can significantly prolong working life of hose assembly.
The beneficial effects of the utility model are that the fire-resistant hose assembly fabricating cost of this water-cooled is low, simple in structure, make fast, and are easy to use, are easy to maintenance, can both carry out effectively fire-resistant heat-resisting radiation shielding to flexible pipe tube head and pipe joint place.The fire-resistant hose assembly of this water-cooled can improve greatly than the fire-resistant resistance to heat emission of the outer glue flexible pipe of interior fibre.Can make flexible pipe and joint under hot environment, in occasion near naked light and infrared source, safety and the use of long period, this hose assembly can not advance to split in the long time or pull when breaking out of fire, and attended operation is simple between the flexible pipe.
