Description
Technical field
This utility model is related to high temperature high voltage resistant flexible pipe, and in particular to a kind of self-cooled high temperature high voltage resistant flexible pipe.
Background technology
The working motion of the equipment such as the clay gun of blast furnace stokehold, tapping machine is, by hydraulic oil cylinder driving, to drive cylinder movement
Hydraulic oil conveyed by high temperature high voltage resistant flexible pipe.Resistance to height is adopted mostly currently used for the high-pressure hose of such hydraulic oil conveying
Warm sebific duct, as clay gun and tapping machine are in more than 1000 degree of high temperature position in operation process, even resistance to elevated temperatures
Preferably sebific duct is also easily aging, causes oil leak, the generation of sebific duct pyrophoricity accident, there is huge potential safety hazard.
The content of the invention
The purpose of this utility model is for the problems referred to above, there is provided a kind of self-cooled of the extremely strong pressure of high temperature high voltage resistant performance
High temperature high voltage resistant flexible pipe.
The technical scheme for realizing above-mentioned purpose is：A kind of self-cooled high temperature high voltage resistant flexible pipe, includes sebific duct, the sebific duct
Core pipe is withheld by withholding set connection respectively in two ends, and two withhold the outboard end difference assembly connection locknut of core pipe；The sebific duct,
Withhold set and withhold, the cooling water cavity is by being arranged on the sebific duct, withhold set and withhold core
The metal bellow of tube outside and the two ends tube sealing composition for being welded on the metal bellow two ends, described end seal sealing of tube
The outboard end for withholding core pipe is fixed on, on the two ends tube sealing, cooling water connecting pipe for water is respectively equipped with.
Further, described core pipe of withholding is divided into two sections and the internal heat insulation loop for water cavity is welded in the middle of its two sections.
Further, metal net cover is provided with outside the metal bellow, the metal net cover is respectively arranged at two ends with
Net end fixing hoop.
This self-cooled high temperature high voltage resistant flexible pipe makes whole glue by arranging water-cooling structure in the outside of high temperature high voltage resistant sebific duct
Pipe works under the protection of cooling water such that it is able to make reliably working under its hyperthermia radiation environment more than 1000 degree, it is ensured that
Work safety, and greatly improve its service life.
This self-cooled high temperature high voltage resistant flexible pipe will be withheld core pipe and be divided into two sections and weld in the middle of its two sections internal for water cavity
Heat insulation loop, and avoid withholding core pipe external radiation high temperature be transmitted to the sebific duct part for contacting, it is to avoid the sebific duct part
It is aging by high temperature action and damage and leakage occurs in the coupling part.
This self-cooled high temperature high voltage resistant flexible pipe arranges metal net cover in the outside of metal bellow, can be to wavy metal
Flexible pipe forms good protection.

Specific embodiment
With reference to the accompanying drawings and examples specific embodiment of the present utility model is illustrated.
As Fig. 1, this self-cooled high temperature high voltage resistant flexible pipe include sebific duct 1, the sebific duct 1 adopts high temperature high voltage resistant sebific duct.Sebific duct 1
Two ends withhold 2 connection of set by a pair be nested with its two ends respectively and withhold core pipe 3 a pair, two withhold the outboard end of core pipe 3
It is provided with connection bulge loop and is coordinated with connecting lock nut 4 by the bulge loop and realizes the connection for withholding core pipe 3 and connecting lock nut 4.In sebific duct
1st, withhold set 2 and withhold the outside of core pipe 3 and be provided with cooling water cavity, the cooling water cavity by being arranged on sebific duct 1, withhold set 2 and withhold
Metal bellow 5 outside core pipe 3 and the two ends tube sealing 6 for being welded on 5 two ends of metal bellow are constituted.As Fig. 1 is implemented
Example, end seal pipe 6 are made up of with the ring flat-plate for being placed in the body outboard end body, and the body and ring flat-plate can be integrally formed, and can also adopt
Combinative structure is welded with split molding.The ring flat-plate of end seal pipe 6 is nested with is withholding the outboard end of core pipe 3 near connecting lock nut 4
Position, and be connected by welding and withholding core pipe 3.Cooling water connecting pipe for water 7 is respectively equipped with two ends tube sealing 6, two cooling waters connect
, used as cooling circulating water water inlet interface, another is used as water outlet mouthpiece in adapter 7.Above-mentioned Design of cooling Water jacket, makes
Cooling water is entered in the end seal pipe being connected by water inlet interface, then by metal bellow is in other end tube sealing and Jing goes out
Water interface flows out, and forms the circulation of cooling water.
This self-cooled high temperature high voltage resistant flexible pipe, will withhold core pipe 3 and be divided into two sections and weld in the middle of its two sections internal for water
The heat insulation loop 8 in chamber.If Fig. 1 embodiments, heat insulation loop 8 are the cavity becket of square-section, fill in the cavity of the cavity becket
Enter water, the internal diameter of its cavity becket is identical with the internal diameter for withholding core pipe 3.
