Abstract
The utility model discloses an expansion joint of an RH alloy chute, which comprises a shell, a corrugated pipe and a cylinder, wherein the upper end of the shell is provided with an upper flange; the lower end of the corrugated pipe is provided with a lower flange; the cylinder is connected with the lower flange; the shell is internally provided with a wear-resistant inner liner; and the lower end of the shell is provided with a support ring used for supporting the inner liner. The expansion joint can effectively improve the wear resistance, prolongs the service life, and can be conveniently replaced even if the inner liner is worn, thus saving the maintenance cost.
Description
Technical field
The utility model relates to expansion joint, more particularly, relates to a kind of expansion joint of RH alloy elephant trunk.
Background technique
The alloy elephant trunk is provided with expansion joint in external refining (RH) equipment, and this expansion joint is used to connect alloy system and vacuum tank system by air cylinder driven, handles vacuum state in process of production, can add alloy material in real time in vacuum tank.The usage requirement of expansion joint is that gas leakage can not be arranged, and in use any breaking point can not occur, safeguards in case there is breaking point just must change.See also expansion joint shown in Figure 1, traditional 10 and comprise housing 11, bellows 12, cylinder 13, housing 11 is located in the bellows 12, and housing 11 upper ends are provided with upper flange 14, and bellows 12 lower ends are provided with lower flange 15, and cylinder 13 links to each other with lower flange 15.Because what the housing 11 of this expansion joint 10 adopted is the Ordinary Steel material, the impact of alloy material is directly born in its inside, washing away for a long time down of alloy material, very easily damaged, the general life-span is only about 3 months, and in case wearing and tearing will cause the gas leakage of whole system, because whole expansion joint 10 prices are more expensive, the maintenance cost that each replacing brings is very big.
The model utility content
At the above-mentioned shortcoming that exists in the prior art, the purpose of this utility model provides a kind of expansion joint of RH alloy elephant trunk, and this expansion joint has abrasion resistance properties preferably, can increase the service life, and reduces maintenance cost.
For achieving the above object, the utility model adopts following technological scheme:
The expansion joint of this RH alloy elephant trunk comprises housing, bellows and cylinder, and the housing upper end is provided with upper flange, and the bellows lower end is provided with lower flange, and cylinder links to each other with lower flange, is provided with wear-resistant liner in the described housing, and the housing lower end is provided with the support ring that is used to support liner.
Have tapped hole on the described support ring, pass tapped hole by the adjusting bolt and push up mutually with the liner bottom.
Described housing top is higher than the liner top, and the housing top also is provided with the rubber pad that is used for gap between seal casinghousing and the liner.
The material of described liner is a manganese steel.
In technique scheme, the expansion joint of RH alloy elephant trunk of the present utility model comprises housing, bellows and cylinder, the housing upper end is provided with upper flange, the bellows lower end is provided with lower flange, cylinder links to each other with lower flange, be provided with wear-resistant liner in the described housing, the housing lower end is provided with the support ring that is used to support liner.Adopt this expansion joint can effectively improve its abrasion resistance properties, prolong its working life, even liner is worn, also can be easily changeable liner and need not to change whole expansion joint more only, thereby saved maintenance cost.

Embodiment
Further specify the technical solution of the utility model below in conjunction with drawings and Examples.
Please in conjunction with Fig. 2～shown in Figure 4, the expansion joint 20 of RH alloy elephant trunk of the present utility model is basic identical with prior art, equally also comprises housing 21, bellows 22 and cylinder 23, and housing 21 upper ends are provided with upper flange 24, bellows 22 lower ends are provided with lower flange 25, and cylinder 23 links to each other with lower flange 25.Different is, be provided with a wear-resistant liner 26 in this housing 21, can adopt high-abrasive material making such as manganese steel, housing 21 lower ends are provided with the support ring 27 that is used to support liner 26, and on support ring 27, evenly have three tapped holes, passing tapped hole by adjusting bolt 28 pushes up mutually with liner 26 bottoms, be used to regulate the high and low position of liner 26, and adjusting bolt 28 also has the effect of jackscrew concurrently, when changeable liner 26 more, with regulating upwards top of bolt 28, make liner 26 loosening earlier, thereby be convenient to the taking-up of liner 26 with housing 21.Housing 21 tops are higher than liner 26 tops, and housing 21 tops also are provided with the rubber pad 29 that is used for gap between seal casinghousing 21 and the liner 26, and this rubber pad 29 is fastened between liner 26 and the upper flange 24 by the adjusting of regulating bolt 28.
Adopt expansion joint 20 of the present utility model, obviously prolong its working life, and under the situation that liner 26 damages, can be independently changeable liner 26 more, and whole expansion joint 20 need not be changed, thereby saved maintenance cost greatly, can bring considerable economic for enterprise.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model the above embodiment's variation, modification.
