6.3 Other
6.3.1 Safety valve
The purpose of the safety valve is to protect the substation from
excessive pressure.
The blow-off pipe from the safety valve must not be closed. The
blow-off pipe outlet should be placed so that it discharges freely
and it is possible to observe any dripping from the safety valve.
It is recommended to check the operation of safety valves at
intervals of 6 months. This is done by turning the valve head in
direction indicated.
6.3.2 Strainer
Strainers should be cleaned regularly by authorized personnel. The
frequency of cleaning would depend on operating conditions and
the manufacturer’s instructions.
6.3.3 Pressure Absorber
The Pressure Absorber reduces overpressure created in the system
caused by sudden opening/closing of taps, so a discharge outlet
is omitted. The Pressure Absorber can be used as a substitute to
the safety valve.
By reducing such overpressures the Pressure Absorber ensures
proper functioning of the components located in the system. It will
also considerably reduce the noise generated by vibration that
occurs due to the sudden closure of the interceptions.
The Pressure Absorber may not be applied in systems with hot
water circulation.
