Abstract
The utility model relates to a gate valve sealing device, which comprises a wedge block, a rising block, and a disc valve plate, wherein, the conical surface of the wedge block is matched with the conical surface of the rising block; the disc valve plate is arranged at one side of the rising block. The utility model is characterized in that a square-shaped through hole is arranged in the wedge block; a square-shaped sliding hole block is arranged in the square-shaped through hole; the height of the square-shaped sliding hole block is smaller than the height of the square-shaped through hole; a gap is formed after assembly; a tap of the disc valve plate is positioned in the square-shaped sliding hole block. The utility model overcomes the defects of the common gate valve sealing devices of fast abrasion of sealing surface and narrow applicable range, and has the advantages of simple structure, easy and flexible open, good sealing effect, strong reliability, and long service life.
Description
The utility model relates to a kind of Gate-valve sealing device.
The Gate-valve sealing device of present known use, the wedge-type that also has that has makes up, but when this wedge-type is combined in valve opening, all do not eliminate the sealing friction, in long-term using process, disk valve plate and valve seat have wearing and tearing and scratch with being difficult to avoid, therefore, the seal arrangement of this gate valve can only be confined to the low pressure occasion and use, and Applicable scope is wideless.
The purpose of this utility model is the above-mentioned defective that overcomes prior art, thereby provides a kind of simple in structure, good seal performance, can eliminate the sealing surface wear when opening, the Gate-valve sealing device of long service life.
The utility model comprises voussoir, piece and disk valve plate rise, the voussoir conical surface matches with the piece conical surface that rises, the disk valve plate is arranged on piece one side that rises, in voussoir, be provided with a square through hole, the built-in square slide opening piece of square through hole, the height of square slide opening piece is less than the height of square through hole, and the assembling back forms the gap, and the tap of disk valve plate is positioned in the square slide opening piece.
Further illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Accompanying drawing is a structural representation of the present utility model.
As shown in the figure, the utility model comprises voussoir 1, piece 2 and disk valve plate 3 rise, the upper end of voussoir 1 and valve rod 8 are affixed, voussoir 1 conical surface matches with piece 2 conical surfaces that rise, and the inclined-plane tapering of voussoir 1 is the 18-24 degree, is provided with a square through hole 4 in voussoir 1, square through hole 4 built-in square slide opening pieces 5, the height of square slide opening piece 5 is less than the height of square through hole 4, and the assembling back forms gap 6, and the tap 7 of disk valve plate 3 is positioned in the square slide opening piece 5.Because valve is when opening, valve rod 8 drives voussoir 1 and rises, need the square through hole 4 in elder generation's elimination voussoir 1 could drive 3 risings of disk valve plate with the gap 6 that square slide opening piece 5 assembles back formation, in the process of eliminating gap 6, voussoir 1 rises, and disk valve plate 3 is internally moved mutually with the piece 2 that rises by pressure medium simultaneously, and the gap between Sealing increases, do not have easily unlatching of friction thereby reach, can not make sealing surface wear and pull.
The utility model is by above specific design, have simple in structure, open easy and flexible, good sealing effect, The advantage of long service life is suitable for using in the gate valve under various high and low pressure environment.
