Multifunctional combined type gasbag device

Abstract

The invention relates to a multifunctional combined type gasbag device, and relates to a gasbag device. The multifunctional combined type gasbag device is provided with a gasbag device, a gasbag charging-discharging and pressure regulation device and a gas flow control device, wherein the gasbag device is provided with a gasbag, the two ends of the gasbag are both provided with metal rings, the metal rings are provided with gasbag charging interfaces, air supply interfaces (used for supplying air to a closed region) and suspension link interfaces; the air supply interfaces are communicated with a vent pipe which penetrates through the whole gasbag, and the gasbag charging-discharging and pressure regulation device is provided with a first gas cylinder, a first leather hose, a pressure control valve, a gasbag pressure indicating meter, a first gas cylinder pressure indicating meter, a first gas cylinder tee joint and an air outlet valve; and the gas flow control device is provided with a second gas cylinder, a second leather hose, a relief valve, a gas flow indicating meter, a second gas cylinder pressure indicating meter, a second gas cylinder tee joint and a gas flow regulating valve.

Description

technical field [0001] The invention relates to an airbag device, in particular to a multifunctional combined airbag device. Background technique [0002] During the welding process, the inside of the pipe (such as stainless steel, titanium, etc.) needs to be filled with inert gas (commonly used argon) to protect the welded joints to ensure the quality of the joints inside. Usually, various types of blocking plates are made on the construction site according to various models and specifications of pipelines. In this traditional method, on the one hand, the blocking plate produced is not tight enough to seal, resulting in too much waste of argon; on the other hand, the blocking plate can only be used correspondingly to the pipeline of the corresponding specification, and its application range is greatly limited; Furthermore, the blocking boards made are rough, of poor quality and have a short service life, resulting in excessive labor and material input.
