Rubber membrane seal gas tank with air-jet air cushion buffer device

Abstract

The invention belongs to the technical field of gas tanks, and relates to a rubber membrane seal gas tank with an air-jet air cushion buffer device characterized by wrapping a piston through air-jet air cushion air bags. The rubber membrane seal gas tank with the air-jet air cushion buffer device comprises a gas tank barrel, a rubber membrane for sealing the gas tank, and the gas tank piston, wherein a buffer device for spraying a gas to an inner wall of the gas tank barrel is arranged on the upper part of the gas tank piston, and comprises multiple groups of air-jet air cushion air bags uniformly arranged in a circumferential direction of the gas tank piston through an air-jet air cushion air bag fixing device; a gas inlet pipe sharing one gas source is arranged on each group of air cushion air bag; and the gas source is connected with each gas inlet pipe through a gas inlet pipeline. The problems that when the piston on the gas tank sealed by the one-part form rubber membrane runs toa high position, the rubber membrane winding on the piston is easy to peel off, so that the gravity center of the piston is far away from the rubber membrane, the piston is interfered, and the pistonis collided and rubbed with an outer barrel body so as to cause the damage of the outer barrel body are solved.

Description

technical field [0001] The invention belongs to the technical field of gas cabinets, and relates to a rubber film-sealed gas cabinet with a jet-type air-cushion cushioning device through which a jet-type air-cushion air-wraps a piston. Background technique [0002] The sealing form of the gas cabinet is divided into dry and wet. The wet gas cabinet with water as the sealing medium has been eliminated now, leaving only the dry gas cabinet (the storage pressure is at the kPa level). [0003] Among the dry gas cabinets, there are gas cabinets that use thin lubricating oil as the sealing medium for sealing, gas cabinets that use rubber film as the sealing medium for sealing, and gas cabinets that use dry lubricating oil as the sealing medium for sealing. [0004] The gas cabinet (also known as the Kolon cabinet) that uses dry lubricating oil as the sealing medium for sealing, because this type of cabinet has high bearing capacity and fast piston running speed. However, due to t...

Problems solved by technology

[0008] In view of this, the present invention aims to solve the problem that when the piston on the one-stage rubber film sealed gas holder runs to a high position, the rubber film wound on the piston is easy to peel off, so that the center of gravity of the piston is far away from the rubber film, the piston is disturbed, and the piston and the outer cylinder To solve the problem of body collision and friction, resulting in damage to the outer body, a rubber membrane sealed gas holder with a jet air cushion buffer device is provided
