Description
Technical Field
The utility model relates to the technical field of electric power safety, in particular to a wall body perforated fireproof plugging device.
Background
In a power plant, process pipelines need to be connected with other pipelines across different process rooms or plants due to the requirements associated with process systems; in order to meet the construction requirement of the process pipeline, holes need to be formed in the wall body of a building, wherein the holes need to penetrate through the wall body of the building. The size of the wall body opening needs to be matched with the appearance size of a process pipeline, and space requirements such as construction allowance, installation error, pipeline thermal displacement, pipeline heat preservation and the like are also considered, so the size of the wall body opening of the process pipeline is generally far larger than the size of the pipeline, and for the purpose of fire prevention, a plugging device needs to be designed on the wall body opening, and the fire prevention plugging refers to the fire prevention separation of various openings formed when various penetrations such as cables, air pipes, oil pipes, air pipes and the like penetrate through the wall (warehouse) wall and the floor (first) plate so as to prevent the fire from spreading through the openings and gaps.
In the prior art, the scheme of wall plugging is generally simple and easy to plug according to the field requirements, and the plugging method still has more defects in the aspects of attractiveness and fireproof function, for example, the holes of some old power plants are not plugged, and because part of the holes are too large, fire can enter a factory building through the holes or along a pipeline, so that the production safety is influenced; and because of the existence of the holes, the integral aesthetic property of the wall body of the outer facade of the building can be influenced to a certain extent.
In the prior art, a soft material (such as a heat insulation material) is adopted to fill a gap between a process pipeline and a wall body opening, and in the direct filling mode, the pipeline with large thermal displacement can take the filler out of the gap to fall off due to the existence of friction force between the pipeline and the filler when the pipeline axially displaces; or because the pipeline compresses tightly soft material along the radial thermal displacement of trompil when great, and the clearance is too big in one side in addition, and leads to the unable completion in trompil clearance to fill, loses the effect of fire prevention shutoff, and wherein, pipeline thermal displacement means because when the high temperature medium that flows through in the pipeline is higher than ambient temperature, the pipeline forms the phenomenon that the pipeline removed because of self expend with heat and contract with cold. For pipelines with slightly large vibration, the plugging material may deform or displace under long-time operation, so that the plugging effect is lost. After the soft material is filled, no corresponding restriction exists, the material is greatly deformed and may be extruded, and the effect of opening sealing and beautifying can not be realized from the outside.
Therefore, a wall body perforated fireproof plugging device which can stably fix a pipeline, has good appearance and is not easy to deform and shift is needed.
