Valve plugging the security technology
May 10, 2012
Valve plugging with pressure and temperature operation, with some difficulty
and danger, as long as the operating personnel in the plugging of security
technologies, strict compliance with the plugging of Practice for plugging in
the accident was
avoidable-china valve.
Datian Valve, the specialist of china valve manufacture(china valve supplier).
1. valve plugging safety knowledge(china heat pump)
(1) combustion accompanied by fever and a luminous chemical reaction phenomena.
Combustion of the combustible material must have, of combustion, the ignition source
of the three conditions. Such as petroleum products are flammable substances around
it is full of air, fire source must be strictly controlled in order to avoid fires, and to
develop a set of use of fire management system. Therefore, in the open flame is prohibited
when plugging, welding, do not use sparking tools.
(2) the explosion of instant gas produced a huge shock wave right severe destructive
phenomenon. It is divided into physical and chemical explosion two. The chemical
explosion must have the combustible explosive material, flammable and explosive
substances and air mixture to reach the explosive limit, and detonated the source
of the three conditions. Should be in plugging ventilation, cooling insulation to
prevent static electricity, open flame is prohibited or to comply with the flare
requirements.
(3) poisoning of a substance into the body caused by any disease of the entire body
dysfunction. Cause poisoning substance to sub-toxic and toxic. Therefore, plugging
in the infected, should be taken to the mutual rotation of the operation, ventilation,
standing on the limelight, with a good antivirus supplies and other measures.
Because many of the toxic substances with flammable and explosive substances,
plugging, the need to fire and explosion.
(4) radiation damage body tissues and organs by the role of certain doses
of radiation, a series of pathological changes in the process. Plugging should
wear a good anti-radiation injury of supplies and masks, setting radiation
protection barriers to prevent radioactive flue dust from entering the body,
resulting in ray bodily harm.
(5) other injuries such as burns, frostbite, shot, burns. The body should avoid
plugging the media fired baffle dressed supplies to prevent injury.
Some media has a variety of dangers, requires the use of a variety of preventive
measures.
2.valve plugging security appliances
Valve plugging installed for safety-related technical regulations and set of tools and
equipment required to wear protective equipment, they shall comply with the
fire and explosion prevention, water and oil repellency, anti-virus, anti-corrosion,
anti-hot antifreeze, radiation, etc., in accordance with conditionsconditions
of security requirements.
