Rope-free leveling system rubber membrane sealing coal gas cabinet

Abstract

The invention discloses a rope-free leveling system rubber membrane sealing coal gas cabinet which comprises a coal gas cabinet barrel. A gas inlet and outlet is formed in the bottom of the coal gas cabinet barrel, sliding H-type pistons capable of sliding along the inner wall of the coal gas cabinet barrel are arranged in the coal gas cabinet barrel, the sliding H-type pistons comprise barrel-shaped rail frames capable of sliding along the inner wall of the coal gas cabinet barrel, rubber sealing membranes are arranged on the outer walls of the barrel-shaped rail frames, inner container pistons are arranged on the inner walls of the barrel-shaped rail frames, the inner container pistons can slide along the inner walls of the barrel-shaped rail frames, upper limiting columns preventing the inner container pistons from sliding out are arranged at the tops of the barrel-shaped rail frames, the inner container pistons comprise barrel-shaped supporting trusses and arched piston plates, the arched piston plates are arranged at the bottoms of the barrel-shaped supporting trusses, and inner container rubber sealing membranes are arranged between the barrel-shaped supporting trusses and the inner walls of the barrel-shaped rail frames. According to the rope-free leveling system rubber membrane sealing coal gas cabinet, the tumbler self-balance principle of the sliding H-type pistons is utilized, a traditional steel wire rope leveling system device is eliminated, the coal gas cabinet structure is optimized, the safety of the coal gas cabinet is improved, maintenance cost is lowered, the steel consumption amount of the coal gas cabinet is lowered, and competitive capacity is improved.

Description

technical field [0001] The invention belongs to the field of gas cabinets, and in particular relates to a rubber membrane-sealed gas cabinet with a cordless leveling system. Background technique [0002] In the dry gas cabinet, there are mainly two types: one is the gas cabinet that uses thin lubricating oil as the sealing medium for sealing, and the second is the gas cabinet that uses rubber membrane sealing. In thin oil sealing, the new type of cabinet is particularly popular because of its good sealing performance. However, in the current thin oil-sealed gas holders, the piston running speed is generally below 2.5m / min, which is mainly affected by various factors, such as the production and installation accuracy of the gas holder cylinder; and the height of the thin oil in the piston. Stable maintenance, etc., these factors have caused the difficulty of increasing the speed of the piston. The gas holder with rubber membrane seal is a leather bag formed by rubber membran...

Problems solved by technology

However, due to the high diameter-to-height ratio of the piston in the one-stage type, the rigidity of the piston is small. If no measures are taken, the piston will easily deform and the gas holder cannot be produced normally. Therefore, most of the existing one-stage types have small capacity. Due to the above-mentioned defects of the formula, there are two improved one-stage piston gas holders in the prior art, one is a fixed H-type piston rubber membrane sealed gas holder, that is, the entire piston section looks like an H shape, and the other is It is a sliding H-type piston rubber membrane sealed gas cabinet. The sliding H-type piston rubber membrane sealed gas cabinet integrates all the advantages of traditional two-stage piston gas cabinets, fixed H-type piston gas cabinets and traditional one-stage piston gas cabinets.

However, the sliding type H-piston rubber-membrane-sealed gas holder or the fixed H-type piston gas holder are not ideal, and a wire rope leveling system device is required during its operation, and the wire rope is at risk of breaking
