Suspension cable type flexible piston arch of gas holder and rubber-film-sealed gas holder

Abstract

The invention discloses a suspension cable type flexible piston arch of a gas holder, which comprises a piston rack and a piston plate installed on the piston rack, wherein a suspension cable net fixedly installed on the piston rack is arranged above the piston plate; a skeletal net used for supporting the piston plate is arranged under the piston plate; and a suspension rope mechanism in gas tightness fit with the piston plate is arranged between the suspension cable net and the skeletal net. The invention also discloses a rubber-film-sealed gas holder, which comprises a gas holder body, wherein the gas holder body comprises a side plate, the inside of the gas holder body is provided with the suspension cable type flexible piston arch; and a rubber film is arranged between the piston rack and the side plate. By improving the rigidity and the intensity of the suspension cable type flexible piston arch of the gas holder, impact force generated when the piston is grounded can be resisted by the suspension cable type flexible piston arch, the suspension cable type flexible piston arch is not only suitable for gas holders with relatively large height-diameter ratios, but also capable of utilizing 20% of volume of the lower part of the gas holder so as to efficiently increasing the available volume of the gas holder, and the suspension cable type flexible piston arch can be used for storing low-pressure gas..

Description

technical field [0001] The invention belongs to the technical field of gas storage, in particular to a cable-suspended flexible piston arch of a gas cabinet and a rubber film-sealed gas cabinet using the piston arch. Background technique [0002] In the existing dry-type gas holders, there are mainly two types: one is a gas holder that uses dilute lubricating oil as a sealing medium for sealing, and the other is a gas holder that uses a rubber membrane to seal. In the thin oil seal, it includes metal sliding plate-type Man cabinet sealing device and rubber seal new cabinet sealing device. Because the rubber seal of the new cabinet has the advantages of good sealing performance, the new cabinet is favored alone. [0003] However, due to the influence of various factors on the current thin oil-sealed gas, the piston running speed is relatively slow, below 2.5m / min. The main factors affecting the speed of the thin-oil-sealed gas piston are: the manufacturing accuracy and instal...

Problems solved by technology

However, because the diameter-to-height ratio of the piston in the one-piece Wiggins cabinet is too high, the rigidity of the piston is small. If no measures are taken, the piston will easily deform and the gas cabinet cannot be produced normally. Therefore, the existing one-piece Wiggins Most of the cabinets are small in capacity

How to solve the problem that the diameter-to-height ratio of the one-stage Wiggins cabinet is too high leads to a decrease in the rigidity of the piston, which has become a technical bottleneck for increasing the capacity of the one-stage Wiggins cabinet

[0006] The existing Wiggins cabinet piston arch uses a soft leather arch, and the piston is supported by a supporting steel pipe when it lands. In order to prevent the impact of the piston when it lands, the state stipulates that 20% of the lower part of the piston cannot be used, that is to use the lower 20% of the piston. % of the gas supports the soft skin arch of the piston, which not only wastes a lot of gas tank volume, but also is extremely inconvenient during construction and maintenance

In addition, the existing rubber-membrane-sealed gas holders are often used to store gas whose pressure is lower than 2kPa. For gas whose pressure is lower than 2kPa, the soft leather arch used in the piston arch of the existing Wiggins cabinet is too soft.
