Gas tank piston annular multi-chamber air bag air pressure leveling device

Abstract

The invention discloses an annular multi-cavity airbag air pressure leveling device of a gas cabinet piston. The annular multi-cavity airbag air pressure leveling device comprises a plurality of independent airbags, wherein the airbags are arranged between a gas cabinet cylinder and the gas cabinet piston; each airbag is provided with an air inlet pipe, an air outlet pipe and an air inlet and outlet control system; the airbags are fixedly arranged on the gas cabinet piston through a balance supporting device. The annular multi-cavity airbag air pressure leveling device disclosed by the invention is equivalent to place a plurality of airbags with air pressure around the piston, so that the piston is protected, and meanwhile, the operating of the piston is not limited; the airbags and cylinder side plates are in surface contact, and the contact stress is very small, so that the stability of the gas cabinet piston and the operating speed of the piston are greatly increased.

Description

technical field [0001] The invention belongs to the field of gas cabinets, and in particular relates to an annular multi-chamber air bag air pressure leveling device for gas cabinet pistons. Background technique [0002] In the existing gas cabinets, except the rubber film sealed gas cabinets, the usual dry gas cabinets need to arrange guide wheels on the piston, and the thin oil sealed gas cabinets are provided with iron guide wheels (there are fixed guide wheels and spring guide wheels). ), and it is closely attached to the inner surface of the cylinder column of the gas holder, and is divided into upper and lower guide wheels. And what dry oil sealed gas holder is provided with is wooden guide wheel (all is spring wooden guide wheel), and wooden spring guide wheel is divided into upper and lower layers. In order to keep the liquid level in the oil groove of the thin oil sealed gas holder piston stable and prevent the iron guide wheel from pressing against the side plate,...

AI Technical Summary

Problems solved by technology

However, although the wooden spring guide wheel of the dry oil-sealed gas cabinet is good, because it is in contact with the side plate at multiple points, the side plate is often deformed after long-term use. In order to avoid the deformation of the side plate, the usual method is to thicken the side plate of the gas cabinet At the same time, it is necessary to reduce the spring strength, and it is also necessary to increase the diameter of the wooden guide wheel to reduce the contact pressure. Therefore, the use of dry oil gas tanks has been limited for many years
