Background

Sodium cyanide, in the form of white crystalline particles or powder, is deliquescent and has a weak bitter almond taste. It is extremely toxic, and can be poisoned and killed when skin wound is contacted, inhaled and swallowed. Sodium cyanide is decomposed by heating to generate hydrogen cyanide, and the boiling point of the hydrogen cyanide is 26 ℃.

At present, sodium cyanide is generally placed into a storage tank for storage, a breather valve is arranged on the storage tank, the breather valve is a valve which ensures that an inner cavity of the storage tank is isolated from the atmosphere within a certain pressure range and can be communicated with the atmosphere when the pressure exceeds or is lower than the pressure range, and the storage tank is placed to be damaged due to overpressure or vacuum during the action of the breather valve.
