U-Emerson wethula i-SIL 3-certified valve assemblies

I-Emerson yethule ama-valve wokuthoma ahlangabezana neemfuneko zendlela yokuklama ye-Safety Integrity Level (SIL) 3 ngokuya kwe-International Electrotechnical Commission's IEC 61508 standard. Abadobi labaUkuzihlukanisa kwedijithaliiinsombululo zezinto zokugcina zisebenzela iindingo zamakhasimende zamavalvu wokuvala eensetjenzisweni zehlelo lokuphepha eliqakathekileko (SIS).

Ngaphandle kwesisombululo lesi, abasebenzisi kufanele bacacise zoke iingcenye zevalvu, bathenge ngayinye, bese bazihlanganisa zibe yinto esebenzako. Ngitjho nanyana amagadango la enziwa ngendlela efaneleko, umhlobo lo wokuhlanganisa ngokwezifiso angeze wanikela ngazo zoke iinzuzo zokuhlangana kwe-Digital Isolation.

Ukwenza ivalvu yokuvala ukuphepha kumsebenzi onzima. Ubujamo obujayelekileko nobumbi bendlela kufanele buhlolwe begodu buzwisiswe lokha nakukhethwa iingcenye zevalvu ne-actuator. Ukungezelela, ukuhlanganiswa okufaneleko kwama-solenoids, amabhakede, ama-couplings nezinye iinsetjenziswa eziqakathekileko kufanele kucaciswe begodu kufaniswe ngokutjheja ne-valve ekhethiweko. Enye nenye yalezi zingcenye kufanele isebenze ngayinye begodu ngokubambisana ukuze isebenze.

U-Emerson ulungisa iindaba lezi nezinye ngokunikela nge-digital Isolation shutdown valve assembly, eyenzelwe ikambiso ngayinye. Iingcenye ezihlukahlukeneko zikhethwe ngokukhethekileko ukwanelisa iimfuneko zesicelo. Ihlangano yoke ithengiswa njengeyunithi ehlolwe ngokupheleleko begodu eqinisekisiweko, enenomboro eyodwa ye-serial kanye namadokhumende ahlotjaniswa nawo aveza imininingwana yengcenye ngayinye yomhlangano.

Ngombana umhlangano wakhiwe njengesisombululo esipheleleko eensetjenzisweni ze-Emerson, uzikhakhazisa ngezinga elithuthukisiweko lokuhluleka ngokufunwa (i-PFD). Kwezinye izehlakalo, izinga lokubhalelwa komhlangano lizokufika ku-50% ngaphasi kokuhlanganiswa kweengcenye ezifanako zevalvu ezithengwe ngamunye begodu zihlanganiswe msebenzisi wokugcina.
