Description

Air bag type pipeline isolator

Technical Field

The utility model relates to a pipeline maintenance technical field, concretely relates to gasbag formula pipe isolator.

Background

In the process of repairing, maintaining or replacing the toxic and harmful gas pipeline, the pipeline needs to be effectively isolated and the valve needs to be closed, so that maintenance personnel or operating personnel are prevented from being damaged by toxic and harmful media, but sometimes, operators are not communicated smoothly with one another, so that the valve is opened mistakenly or is not isolated, and the toxic and injured accidents of the personnel are caused. Especially, when the caliber of the pipeline is large, the danger coefficient of an internal operator is exponentially increased when a person enters the interior of the pipeline to repair or modify the equipment, and the external unsafe factors can influence the safety risk of the internal operator of the pipeline. When the toxic and harmful media in the wrong pipeline are conveyed, the safety of personnel working in the pipeline cannot be effectively protected and guaranteed, and the personnel can be injured or die when the individual protection is disabled. Therefore, the risk to the staff is greatly increased if no effective protective measures are provided.

Therefore, when working in a poisonous and harmful closed space, the operator needs to ventilate and then check, and then enters the operation after the check is qualified. Meanwhile, the operator wears a detectable detection instrument, and when the environment is abnormal, an alarm of the detection instrument gives an alarm to remind the worker that harmful and toxic gas in the pipeline exceeds a specified value and the worker is required to evacuate from the site in time. When the delivered medium is a slowly increasing process, the relevant person can withdraw in a short time; when the medium to be fed is a large amount of variable which is instantaneously increased in a short time, even if the toxic and harmful medium is detected, the person cannot withdraw in a short time, resulting in a personal injury accident of the sender. Particularly, in the process of welding open fire operation, when a large amount of combustible gas, such as coal gas, natural gas and the like, is fed suddenly, the combustible gas immediately catches fire when meeting the open fire to reach the explosion limit, and because the combustible gas is fed at a high speed and in a large amount, the operator does not have enough reaction time, so that the operator is burnt or injured, and the resultant influence is large.

Working in a closed pipeline, the absence of effective secondary isolation equipment is an important factor which causes that personnel often have insufficient evacuation time and accidents occur. Therefore, in the pipeline maintenance, the protection measures need to perform secondary protection on the operating personnel by other protections besides individual protection, so as to reduce the safety risk to the minimum and improve the intrinsic safety factor.
