The aluminum silicate fiber felt has inherent characteristics of fire resistance, high temperature, heat insulation, heat preservation and the like, and can effectively prevent flame from penetrating and spreading. However, under the demand of higher and higher fire endurance, the prior art plate member is not effective in fire resistance, heat insulation and smoke prevention under the condition of 4h fire endurance. Therefore, it is an urgent technical problem to be solved by those skilled in the art to develop a new sealing structure for a converter transformer valve hall to improve its fire-resistant, heat-insulating and smoke-proof performance.

Further, the aluminum silicate fiber felt is a high-density aluminum silicate fiber felt.
Further, the heat insulation layer is a hollow extrusion molding cement board or a gypsum board.
Further, the heat insulation layer is a hollow extrusion-molded cement board.
Furthermore, the thickness of the plugging plate is 135mm, the thickness of the heat insulation layer is 90mm, and the thickness of the floating bead particle plate is 40 mm.
Further, the thickness of the heat insulation layer can also be 60-90 mm.
Has the advantages that:
according to the plugging plate for the converter transformer valve hall, when a fire disaster occurs, the fireproof coating improves the fireproof capacity of the fireproof layer of the plate, slows down the spreading speed of flame, or can stop burning within a certain time, retards the rapid spreading of the fire disaster, and improves the fireproof limit of the plate.
The floating beads and the inorganic bonding agent at the joints of the fireproof layer of the plate are blocked, so that the weak links at the joints are eliminated, and the integral fireproof limit of the fireproof layer is improved.
The aluminum silicate fiber felt at the joints of the heat insulating layers of the plates reduces the heat and smoke transmission.
The fire-proof sealant at the seam of the fire-facing side of the heat-insulating layer prevents the smoke from transmitting.
Meanwhile, the plugging material can not be burnt, and toxic smoke can not be generated.
The plugging plate for the converter transformer valve hall, provided by the invention, can effectively resist fire, insulate heat and prevent smoke under the condition of a fire-resistant limit of 4h, and meanwhile, has strong operability in engineering application.
