Abstract
The utility model discloses a warm-air pipe corrugated inner discharging pipe expansion joint which comprises connecting pipes (1), a middle connecting pipe (2) and corrugated pipes (3), wherein the two ends of the middle connecting pipe (2) are both connected with one ends of the corrugated pipes (3), and the other ends of the corrugated pipes (3) are connected with the connecting pipes (1). The warm-air pipe corrugated inner discharging pipe expansion joint is characterized in that pipe bodies (4) are arranged in corrugations of the corrugated pipes (3), the pipe bodies (4) are connected to discharging pipes (5), and one ends of the discharging pipes (5) stretch out from the middle connecting pipe (2) and stretch to the outer portion of a warm-air pipe. The warm-air pipe corrugated inner discharging pipe expansion joint is compact and reasonable in structure design, condensate in corrugations can be discharged from the discharging pipes when a valve is opened, the expansion joint can be prevented from being corroded, and the product technical index and quality reach the international advanced level.
Description
Technical field
The utility model relates to a kind of expansion joint, specifically a kind of expansion joint that is installed on the hot blast stove system hot air duct in the ripple with discharge pipe.
Background technique
The effect of hot blast stove is to provide 1000 degree above high-temperature hot-air for blast furnace is continual, general large blast furnace need to be equipped with 3 above hot blast stoves, guarantee in the situation of 1 hot blast stove maintenance, to adopt other several hot blast stove work, make blast furnace production excessive fluctuation can not occur.High-temperature hot-air is sent into blast furnace by hot air duct, is installed on the expansion joint compensation hot air duct of hot air duct or the relative displacement between hot blast stove and the hot air duct.Repair at hot blast stove in the situation of wind or maintenance, inside temperature can descend, and hot air duct expansion joint lower corrugation part can produce condensed water.The inner original thermal insulating material of the mixed expanded joint of condensed water can cause corrosion to ripple.Present hot air duct expansion joint can't be discharged the condensed water of ripple inside, for the expansion joint operation brings hidden danger.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned the deficiencies in the prior art, and a kind of compact structure, reasonable is provided, and can discharge the interior band of the hot air duct ripple discharge pipe expansion joint of corrugated portion condensed water.
The technical solution adopted in the utility model is as follows:
Band discharge pipe expansion joint in a kind of hot air duct ripple, it includes adapter, middle adapter and bellows, the two ends of described middle adapter all connect an end of bellows, the other end connecting tubes of bellows, it is characterized in that being equipped with body in each ripple of described bellows, each body all is connected to discharge pipe, and an end of described discharge pipe extend out to the hot air duct outside from middle adapter.
The end that described discharge pipe stretches out the hot air duct outside is equipped with ball valve.
One end of described discharge pipe stretches out from the hole on the middle adapter, and this hole is provided with and is welded with the shrouding 7 that seals.
Described body extend into bellows ripple inside and reserves certain interval in crest.
The beneficial effects of the utility model have:
Structural design is compact, reasonable, opens the condensed water of valve ripple inside and can discharge by discharge pipe, avoids expansion joint to be corroded, and technical target of the product and quality have reached international most advanced level.
Description of drawings
Fig. 1 is side-looking structural representation of the present utility model.
Fig. 2 is the A-A sectional structure schematic representation of the utility model Fig. 1.
Fig. 3 is the partial enlarged drawing of the utility model Fig. 2.
Embodiment
The utility model is further described below in conjunction with accompanying drawing:
As Figure 1-3, critical piece of the present utility model includes adapter 1, middle adapter 2 and bellows 3, and the two ends of middle adapter 2 all connect an end of bellows 3, the other end connecting tubes 1 of bellows 3.Be equipped with body 4 in each ripple of bellows 3, each body 4 all is connected to discharge pipe 5.One end of discharge pipe 5 extend out to the hot air duct outside from middle adapter 2.Body 4 and discharge pipe 5 are arranged on the downside of hot air duct, and namely bottommost is conducive to the discharge of condensed water.Body 4 extend into the lower end of ripple inside and reserves certain interval in crest, also is convenient to discharge condensed water.Body 4 can be the helical flexible pipe, and the lower end height of body 4 and the distance at crest place are generally reserved the 5mm gap and be advisable.The end that discharge pipe 5 stretches out the hot air duct outside is equipped with ball valve 6, only needs ball valve is just opened and ripple internal condensation water can be discharged, and is easy and simple to handle.The floss hole of discharge pipe 5 also can connect pumping equipment, improves discharge efficiency.One end of described discharge pipe 5 is that the hole on the middle adapter 2 stretches out, and this hole is provided with and is welded with the shrouding 7 that seals.
Other undeclared part that the utility model relates to is same as the prior art.
Claims (4)
1. be with the discharge pipe expansion joint in a hot air duct ripple, it includes adapter (1), middle adapter (2) and bellows (3), the two ends of described middle adapter (2) all connect an end of bellows (3), the other end connecting tubes (1) of bellows (3), it is characterized in that being equipped with body (4) in each ripple of described bellows (3), each body (4) all is connected to discharge pipe (5), and an end of described discharge pipe (5) extend out to the hot air duct outside from middle adapter (2).
2. band discharge pipe expansion joint in the hot air duct ripple according to claim 1 is characterized in that the end that described discharge pipe (5) stretches out the hot air duct outside is equipped with ball valve (6).
3. band discharge pipe expansion joint in the hot air duct ripple according to claim 1 is characterized in that an end of described discharge pipe (5) stretches out from the hole on the middle adapter (2), and this hole is provided with and is welded with the shrouding (7) that seals.
