Abstract
The utility model which belongs to the sealing technical field discloses a coal gas tank sealing device which is composed of two sealing components which are respectively arranged on the top and the bottom along the axial direction of the coal gas tank, a hanging element fixed on a piston ring beam and a hold-down mechanism which is composed of a balance weight, a lever, a hosting cable, a position block fixed on the piston ring beam, a spring board, a pressure lever and a sealing component camber beam. Each of the sealing components contains an upper and a lower sealing rubber blocks separated by a wood block, a rubber gasket, a canvas and a clamping element which are all connected into one body through a screw rod, and the sealing component which is hung on the hanging element of the piston ring beam forces the sealing rubber block to be closely jointed with the inner wall of the side plate through the hold-down mechanism. The coal gas tank sealing device is characterized in that one end of the canvas is arranged between the two sealing rubber blocks and the other end is arranged on the piston ring beam; the clamping force produced by the own clamping element of the sealing components can be used to reduce the gap of the canvas between two adjacent sealing rubber and the sealing oil leakage, ensuring the sealability of the coal gas tank.
Description
Technical field
The utility model belongs to technical field of sealing technology, relates in particular to a kind of sealing device for gas cabinet.
Background technique
In the prior art, a kind of sealing device for gas cabinet of employing by along two groups of black boies of gas cabinet axial direction upper and lower settings, be fixed on the piston ring beam suspension element and by counterweight, lever, wire rope, be fixed in hold-down mechanism that fixed block on the piston ring beam, latch plate, depression bar, black box back of the body beam etc. form etc. and form.Black box comprises that each two caulking gum up and down, rubber cushion blocks, canvas, the clamping member that are separated by wooden unit connect in aggregates by screw rod.Black box is suspended on the suspension element on the piston ring beam, by hold-down mechanism caulking gum is fitted tightly on the inwall of side plate, plays seal action.The pressed component quantity that is arranged circumferentially in level reaches thousands of groups, and the slit is all arranged between every group, and to guarantee gas cabinet cylindrical shell and piston under certain adverse condition such as making precision, temperature deformation and wind load, caulking gum still can be close to side plate.Because canvas can move with black box, the effect of playing pocket oil and keeping black box and piston to flexibly connect, therefore the canvas between adjacent pressed component must leave flexible surplus.The deficiency that this device exists is: because canvas one end is installed between rubber cushion blocks and the caulking gum, the canvas the other end is installed on the piston ring beam.Rubber cushion blocks is different with the function of caulking gum, material has basic difference, and the rubber cushion blocks material is softer, and the caulking gum material is harder, leak into the seal arrangement below below the canvas in the slit of sealing oil between rubber cushion blocks and caulking gum, cause seal failure.
Summary of the invention
The purpose of this utility model is to provide a kind of improved sealing device for gas cabinet, prevents that effectively sealing oil from flowing to the seal failure that the seal arrangement below causes from the below short circuit of canvas.
For achieving the above object, the technical solution adopted in the utility model is: sealing device for gas cabinet by along two groups of black boies of gas cabinet axial direction upper and lower settings, be fixed on the piston ring beam suspension element and by counterweight, lever, wire rope, be fixed in hold-down mechanism that fixed block on the piston ring beam, latch plate, depression bar, black box back of the body beam etc. form etc. and form.Black box comprises that each two caulking gum up and down, rubber cushion blocks, canvas, the clamping member that are separated by wooden unit connect in aggregates by screw rod.Black box is suspended on the suspension element on the piston ring beam, by hold-down mechanism caulking gum is fitted tightly on the inwall of side plate, plays seal action; Canvas one end is installed between two caulking gums, the canvas the other end is installed on the piston ring beam, the clamping force of utilizing the clamping member of black box self to produce reduces the slit of canvas between adjacent seals rubber, reduces the leakage rate of sealing oil, guarantees the sealability of gas cabinet.
The utility model compared with prior art, have following conspicuous advantage: employing canvas one end is installed in the mode between the caulking gum, the clamping force of utilizing the clamping member of black box self to produce reduces the slit of canvas between the adjacent seals rubber, help forming the labyrinth seal pattern on sealing surface, sealability is better; Can also cancel rubber cushion blocks, reduce investment outlay.
