Abstract
The utility model discloses a heavy discharge-suction rubber pipe which is composed of a metallic flange, cords and a pipe core; an inner rubber layer is in tight joint with the external wall of the pipe core; the metallic flange is sleeved on the inner rubber layer; the cords are coiled in two groups; the first group of the cords is coiled on the inner rubber layer and the metallic flange; the second group of the cords is coiled on the upper part of the steel wire; the number of the cords coiling layers is an even integer and the coiling directions of the two adjacent cords coiling layers is opposite; the steel wire is arranged between the two groups of card yarn; an outer rubber layer is wrapped on the second group of the cords. The heavy discharge-suction rubber pipe manufactured with the structure can prevent the outflow of the conveying medium due to low intensity and bad sealing property of the interface, so that the conveying efficiency of the discharge-suction rubber pipe and the safety are improved.
Description
Technical field
The utility model belongs to a kind of row and attracts sebific duct, and particularly a kind of heavy row attracts sebific duct.
Background technique
Sell in the market with the row who uses and attract sebific duct generally to adopt steel pipe to be connected, but this method can not eliminate and connect that steel pipe is perishable, joint strength is low, and influence body sealability and working life.
Summary of the invention
The purpose of this utility model provides a kind of high joint strength, and sealing joint is good, warping strength, the heavy type of stretch-proof row attracts sebific duct.
For achieving the above object, solution of the present utility model is: a kind of heavy row attracts sebific duct, form by interior metal flange, cord, tube core, be glued with inner glue layer on the outer wall of described tube core, described metal flange is enclosed within on the inner glue layer, described cord divides two groups of windings, first group is wrapped on inner glue layer and the metal flange, second group is wrapped in steel wire top, described cord winding layer must be an even number, and the winding direction of adjacent layer must be opposite, and described steel wire is enclosed with outer glue-line on described second group of cord between two groups of cords.
Adopt the heavy row of this structure manufacturing to attract sebific duct can prevent effectively that, sealing difference low because of the interface joint strength from causing the fed sheet of a media outflow, improved and arranged the transfer efficiency that attracts sebific duct, improved Security
Description of drawings
Fig. 1 is the utility model embodiment's a structural representation.
Embodiment
As shown in Figure 1, a kind of heavy row attracts sebific duct, form by interior metal flange, cord, tube core, be glued with inner glue layer 1 on the outer wall of described tube core, described metal flange is enclosed within on the inner glue layer 1, the two groups of windings in 4 fens of described cord, first group is wrapped on inner glue layer 1 and the metal flange 2, second group is wrapped in steel wire 3 tops, described cord 4 winding layers must be even numbers, and the winding direction of adjacent layer must be opposite, and described steel wire 3 is enclosed with outer glue-line 5 on described second group of cord 4 between two groups of cords 4.
