Abstract
The utility model relates to a rectangular air duct rubber compensator, which comprises a flexible compensating tube and clamping-ring flanges arranged at two ends of the flexible compensating tube. The cross section of the flexible compensating tube is square, support rods are evenly distributed on the clamping-ring flanges at the two ends, the tail end of each support rod is provided with a threaded hole, and a connecting screw rod is installed inside the threaded holes of two opposite support rods in a matched manner. The rectangular air duct rubber compensator perfects the structure of a maintenance-free sleeve compensator, greatly increases product working reliability, prolongs the service life and realizes a maintenance-free function due to the fact that volatile component loss in packings increases sealing performance during long-term work at in hot environment, increases product capacity against accidents, and can ensure safety running of a pipe network. The packings with fine performance and advanced injection technique guarantee reliable product sealing. The rectangular air duct rubber compensator has the advantages of simple structure, easy fabrication and processing, convenient use, long service life and the like, and effectively facilitates popularization and practice.
Description
One, technical field:
The utility model relates to the compensation of pipeline element, particularly a kind of rectangular duct rubber compensator.
Two, background technique:
Compensator be used for the suction line system because of expand with heat and contract with cold or other reasons produces axially and the device of radial displacement, be widely used in important industries such as electric power, metallurgy, chemical industry, building, food, pharmacy.For the gas exhaust duct of a high-temperature flue gas of converter and the conveyance conduit of similar high temperature media, compensator must have resistance and high temperature resistance property, and have bigger axially, the performance of radial compensation amount; Contain great number of flammable toxic gas carbon monoxide in flue gas of converter simultaneously, require compensator to have higher sealing; The temperature of a flue gas of converter is periodically variable according to converter process, belongs to 100～1200 ℃ alternating temperature-changing, therefore requires compensator can have the performance of temperature acute variation.Present compensator can not satisfy above requirement far away.
Three, model utility content:
The utility model is to overcome the deficiency that prior art exists, and designs and produce a kind of rectangular duct rubber compensator.
Technological scheme:
A kind of rectangular duct rubber compensator, comprise the flexible compensation pipe, trim ring flange with flexible compensation pipe two ends, the cross section of described flexible compensation pipe is square, on the trim ring flange of two ends, be evenly equipped with strut respectively, and being provided with screw at each strut end, coupling is equipped with connecting screw rod in the screw between relative two struts.
Described flexible compensation pipe is the rubber expansion pipe.
The sidewall cross section of described flexible compensation pipe is " n " shape, perhaps is " Ω " shape.
Described flexible compensation pipe has the square bulge loop of two cross sections for " n " shape at least.
Described flexible compensation pipe has the square bulge loop of two cross sections for " Ω " shape at least.
The beneficial effects of the utility model:
1, rectangular duct rubber compensator of the present utility model, the perfect structure of non-maintaining sleeve compensator, when under the long term thermal environment, working, volatile ingredient loss in the stuffing box packing, make sealability improve, improve the functional reliability and the working life of product greatly, realized non-maintaining function; Improve the ability that product meets accidental contingencies, can guarantee the network security operation; The stuffing box packing of function admirable and advanced injection technique guarantee that product seals reliably.
Advantages such as 2, rectangular duct rubber compensator of the present utility model has simple in structurely, makes easily and processes, and is easy to use, and the life-span is long are beneficial to promotion and implementation very much.
Four, description of drawings:
Fig. 1 is one of the utility model rectangular duct rubber compensator cross-sectional view;
Fig. 2 is the side structure schematic representation of Fig. 1;
Fig. 3 is two of the utility model rectangular duct rubber compensator cross-sectional view;
Fig. 4 is three of the utility model rectangular duct rubber compensator cross-sectional view.
Five, embodiment:
Embodiment one: referring to Fig. 1, Fig. 2, a kind of rectangular duct rubber compensator, comprise flexible compensation pipe 1a (the sidewall cross section of flexible compensation pipe is " n " shape), be provided with trim ring flange 3 at flexible compensation pipe 1a two ends, the cross section of described flexible compensation pipe 1a is square, be evenly equipped with strut 4 respectively on two ends trim ring flange 3, and be provided with screw at each strut 4 end, coupling is equipped with connecting screw rod 5 in the screw between relative two struts 4.
Described flexible compensation pipe is the rubber expansion pipe.
Embodiment two: referring to Fig. 3, content and embodiment one are basic identical, and something in common does not repeat, and different is: described flexible compensation pipe has the square bulge loop of two cross sections for " n " shape.
Embodiment three: referring to Fig. 4, content and embodiment one are basic identical, and something in common does not repeat, and different is: the sidewall cross section of described flexible compensation pipe is " Ω " shape.
