Two-section type rubber film sealing gas cabinet reconstructed from regularly polygonal diluted oil sealing gas cabinet

Abstract

The invention discloses a two-section type rubber film sealing gas cabinet reconstructed from a regularly polygonal diluted oil sealing gas cabinet. The two-section type rubber film sealing gas cabinet reconstructed from the regularly polygonal diluted oil sealing gas cabinet comprises a regularly polygonal cabinet body, a two-section type gas cabinet piston device, a T baffle stand, a T baffle, a first-order sealing mechanism, a second-order sealing mechanism, an inner sleeve and a piston supporting device, wherein the two-section type gas cabinet piston device, the T baffle stand, the T baffle, the first-order sealing mechanism, the second-order sealing mechanism, the inner sleeve and the piston supporting device are arranged in the regularly polygonal cabinet body; the piston supporting device comprises a piston ring beam support and a piston center support; the two-section type gas cabinet piston device comprises a piston ring beam, a piston fence and a piston center ball shell; the T baffle stand is arranged on a bottom plate of the regularly polygonal cabinet body; the T baffle is positioned above the T baffle stand and can vertically move under the effect of an external force; the inner sleeve is arranged in the middle of the inner side of the regularly polygonal cabinet body; the bottom of the inner sleeve is lower than the top of the T baffle stand; the top of the inner sleeve is higher than the bottom of the T baffle when the T baffle ascends; the first-order sealing mechanism is separately connected with the bottom of the T baffle and the bottom of the two-section type gas cabinet piston device; and the second-order sealing mechanism is separately connected with the bottom of the T baffle and the inner sleeve. The two-section type rubber film sealing gas cabinet reconstructed from the regularly polygonal diluted oil sealing gas cabinet is low in investment, short in construction time and considerable in economic benefit.

Problems solved by technology

[0002] At present, many existing polygonal thin oil-sealed gas holders in China have been out of service or "operating with diseases". It has been in disrepair for more than 20 years; (2) Before 2008, the polygonal thin oil-sealed gas cabinets built in China were all low-pressure cabinets (design pressure below 8kPa). Low-pressure polygonal thin oil-sealed gas cabinets can no longer be connected to the grid; (3) polygonal thin-oil-sealed gas cabinets use thin oil and steel sliding plate piston sealing methods, which require high installation accuracy, and many polygonal thin-oil-sealed gas cabinets Due to the insufficient installation accuracy of the cabinet, there are problems such as piston guide wheel jamming and large oil leakage during operation. After overhaul, these problems still cannot be eliminated

[0003] At present, in order to solve the problem of rebuilding such problematic regular polygonal thin oil-sealed gas holders, the technology of converting them into single-stage rubber-membrane-sealed gas holders has been introduced. This technology has been applied in projects such as Zhongtian Iron and Steel Plant. , economic indicators and technical indicators are good, but this technology also has its limitations: (1) The loss of cabinet capacity is more, with Changzhou Zhongtian Iron and Steel Plant 100,000 m 3 Take the renovation project of a regular polygonal thin oil-sealed gas tank as an example, the tank capacity of which is transformed into a single-section rubber membrane sealed gas tank is only 73,000 m 3 (2) The limitation of rubber membrane technology limits the transformation of large-scale regular polygonal thin oil-sealed gas cabinets into single-stage rubber membrane-sealed gas cabinets

At present, the production length of the domestic rubber membrane is about 24m (the foreign technology is only 28m, and the price is more than three times the domestic unit price), and this length is 100,000m 3 The gas tank has been used to the extreme in the transformation, and for the 150,000 m 3 , 200,000 m 3 The transformation of regular polygonal thin oil-sealed gas cabinets is far from meeting the needs of single-section cabinet transformation
