Description: Instruction Thisvalveisusedforpowerplantboilers,pressurecontainers,pressureandtemperaturereducingdevicesandotherfacilities. Structure briefing 1.Thesafetyvalve shallbe installedwertically andit wouldbe betterto installthe valvedirectly uponthe adaptorof thecontcuner orthe pipe.Theinsidediameter ofthe adapforshall beno lessthan thatof theinlet pipeof thesofty valve. 2. To avoid the thermal stress that is caused by the thermalexpansionofthedischargepipe,theexitwayofthesafatyvalve shall be expansion with appropriate expansion joint. Theinsidediameter of the discharge pipe should larger than the diameter oftheexitwayofthevalve.Itslengthshallbeasshortaspossible andnobentisallowed.Theweightofboththedischargepipeand the expansion jointshall not be applied to the safety valve, andtheyshallbefasteneduponthecon-struction.Thedistancebetween bothcenterlinesofthedischargepipeandthebodyshall beasshort aspossible. Awaterdrainagepipeshallbeinstalledseparatelyfor eachsafetyvalve. 3.Theexitwayofthemufflershallhaveenougharea,inorder toavoidproducingbackpressurethatwouldaffectthedischarge capabilityofthevalve.
