Abstract
The utility model discloses a gas conduit-repairing device, which comprises a valve (3), and a blind plate (4) arranged at the position of the flange of the valve (3). The blind plate (4) is on the same horizontal line with the center of the valve (3). A support device is arranged on the outer side of the blind plate (4). The gas conduit-repairing device reduces the initial investment, further simplifies the system, and facilitates operation, and is favorable for reduction of repairing work as well as ensures long-term effective operation. In addition, the space occupied by the gas conduit repairing device and all of appurtenant facilities for hydraulic seal are reduced. The gas conduit-repairing device is simple in structure and effective for use.
Description
Technical field
The utility model relates to shut-off means and its support device on a kind of gas pipe line in a kind of gas pipe line apparatus for examination and repair, the especially alumina factory.
Background technique
At alumina factory, usually all the auxiliary construction gas station comes to provide producer gas for alumina producing.Increase day by day along with alumina technology is production-scale, it is increasing that the capacity of gas station also becomes, can safe operation in order to guarantee explained hereafter, enough shut-off meanss just must be arranged for operation, maintenance and maintenance on gas pipe line.At present, in the cut-out of most gas pipe line, all adopt the dish valve to cooperate as shut-off means with the cut-out water seal.This cut-out is had relatively high expectations to the dish valve, and sealability requires very strict; Also need water seal water.And cut off water seal and also need to purge, the device that diffuses, operation, maintenance are got up very inconvenient.
The model utility content:
The purpose of this utility model is: a kind of gas pipe line apparatus for examination and repair is provided, and it is simple in structure, take up an area of less, easy to use, to overcome the deficiencies in the prior art.
The utility model is achieved in that the gas pipe line apparatus for examination and repair, and it comprises valve (3), is provided with blind plate (4) on the flange position of valve (3), and the center of blind plate (4) and valve (3) is on same horizontal line, and blind plate (4) outside is provided with support device.
Described support device comprises stiffening plate (1), and stiffening plate (1) inboard is provided with fagging (2), and fagging (2) is provided with channel-section steel (5).Utilize object such as jack to strut described support device, make between the flange of valve (3) space to occur,, blind plate (4) is packed into just can play the cutting action of coal gas like this so that take out the blind plate ring between former valve of packing into (3) and flange.Active force acts on the fagging (2), and channel-section steel (5) is used for supporting the objects such as jack that are used for strutting support device.Stiffening plate (1) is used for strengthening fagging (2).
Wherein, valve (3) can be dish valve, gate valve or stop valve.
Be more preferably, the Edge Distance of channel-section steel (5) top and valve (3) is 180～220mm.When installing, dismantling the bolt between valve (3) and flange and strutting equipment, this is apart from the best, and under this distance, active force can strut support device better.
Owing to adopted technique scheme, compared with prior art, the utility model has reduced first investment, make system simpler, made things convenient for operation, helped alleviating staff's maintenance workload, guaranteed the operation that equipment is permanently effective, and reduced occupation of land and reduced all affiliated facilities that water seal brought, simple in structure, using effect is good.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment
Embodiment 1 of the present utility model: the structure of gas pipe line apparatus for examination and repair as shown in Figure 1, on the flange position of valve 3, be provided with blind plate 4, the center of blind plate 4 and valve 3 is on same horizontal line, blind plate 4 outsides are provided with support device, support device comprises stiffening plate 1, and stiffening plate 1 inboard is provided with fagging 2, and fagging 2 is provided with channel-section steel 5, the Edge Distance of channel-section steel 5 tops and valve 3 is 180～220mm, and valve 3 can adopt commercially available dish valve, gate valve or stop valve.
When coal gas need overhaul cut-out, strut the support device of forming blind plate 4 by stiffening plate 1, fagging 2 and channel-section steel 5 with objects such as jack, make between the flange of valve 3 and the space occurs, so that take out former blind plate ring of packing between valve 3 and flange, blind plate 4 is packed into just can play the cutting action of coal gas like this.Avoided using the problem of water seal water and steam blowing.The active force of objects such as jack acts on the fagging 2, and channel-section steel 5 is used for supporting the objects such as jack that are used for strutting support device.Stiffening plate 1 is used for reinforcing fagging 2.The support device biggest advantage is that active force acts directly on the flange of pipeline and valve 3 when having avoided strutting, and pipeline and annex thereof have been played protective action.
Claims (4)
1. gas pipe line apparatus for examination and repair, it comprises valve (3), it is characterized in that: be provided with blind plate (4) on the flange position of valve (3), the center of blind plate (4) and valve (3) is on same horizontal line, and blind plate (4) outside is provided with support device.
2. gas pipe line apparatus for examination and repair according to claim 1 is characterized in that: support device comprises stiffening plate (1), and stiffening plate (1) inboard is provided with fagging (2), and fagging (2) is provided with channel-section steel (5).
