Explosion barrier
Current regulations, in order to limit damage caused by explosions, plan to divide a manufacturing facility in COMPARTMENTS that can be secured to more easily and more efficient than the whole plant..
The use of our valves is crucial to obtain this result, and it is obvious from the following examples:
Suppose we have a very simple installation: a power supply of raw material (silo) A -
Upon occurrence of an explosion in C, the valve B stops it within the compartment delimited by it, avoiding that can propagate in A.
Similarly, if the event occurring in A, could not spread into C .
To make sure of this, it is important and necessary that the valves must be CERTIFIED BIDIRECTIONAL, otherwise the explosion may extend upstream or downstream.
A GENERIC CHART
The diagram shows where they should place safety devices in a system of this kind. Obviously, their types will be different depending on the installation spot and the result you want get.
EXAMPLE 1
The explosion is triggered in the silo A: the intervention of the EXPLOSION BARRIER ROTARY VALVE B blocks its propagation.
EXAMPLE 2
The explosion is triggered in the transport line C: the intervention of the EXPLOSION BARRIER ROTARY VALVE B blocks it and prevents it from spreading.
EXAMPLE 3
The explosion is triggered in the machine D: It spreads along the line C, but at the end the EXPLOSION BARRIER ROTARY VALVE B blocks it.
