Safety Shutoff Valve
MB 2 04 06 / 1
General description
Full-vacuum chlorinators are designed according
to the highest safety standard DIN19606. Even in
the case of a line rupture chlorine gas cannot
escape,onlyambientairissuckedintothevacuum
system. Ifthevacuumregulatorfunctionisfaultya
safety blow-off valve is opened thus providing for
a pressure relief in the vacuum system. This
happens even at low-value overpressure and the
chlorine gas is lead directly to the gas detector.
However,shouldtheunhappycaseoccurthatboth
the vacuum line and the inlet valve are defective,
thesafetyblow-offvalvecannotreact.Asaresultof
the defective vacuum line no overpressure can be
built up. Thus uncontrolled escape of chlorine gas
occurs at another point.
By using the safety shutoff valve this case is
avoided so that the highest possible safety of the
full-vacuum chlorinators is guaranteed.
At the same time the safety shutoff valve prevents
waterfromentering intothevacuumregulatoreven
if the ejector non-return valve is untight.
Function
During operation of a chlorinator acoording to
DIN19606 the ejector builds up a vacuum. As a
result of this vacuum, the safety shutoff valve is
opened via the diaphragm surface first and only
then the vacuum regulator is opened. During
operation the shutoff valve is virtually a mere
connecting pipe for the metering plant.
Iftheejectorisswitchedoff, the vacuumcollapses
and the shutoff valve closes due to spring loading.
Thevalve completely shuts downthemeteringline
sothatevenatahighoverpressureatthevalveinlet
chlorine gas cannot reach the end of the line. By
mountingthesafetyshutoffvlavewithintheareaof
the chlorine gas line being monitored by the gas
warning device the plant is absolutely safe even in
the case of malfunction (see also installation dia-
gram on the back).
