Anvalv globu elettrikuhuwa valv ta 'kontroll awtomatizzat li jikkonsisti f'attwatur elettriku u valv ta' gate. Juża l-enerġija elettrika biex tiftaħ u tagħlaq il-valv jew tirregola l-fluss. Il-komponenti ewlenin tagħha jinkludu attwatur elettriku (parti ta 'fuq) u korp tal-valv tal-bieb (parti t'isfel). Wara li jirċievi sinjal ta 'kontroll, l-attwatur isuq iz-zokk tal-valv, u jikkawża li d-diska tal-valv (korp tal-valv) iddur madwar il-linja ċentrali tal-korp tal-valv, u b'hekk tiftaħ jew tagħlaq il-passaġġ tal-fluwidu.
Il-valvi ta' l-elettriku huma valvi ta' stroke-lineari. B'differenza mill-valvi tal-ballun, li jduru 90 grad biex jiftħu u jagħlqu, id-diski tal-valvi tagħhom jimxu f'moviment lineari u rotatorju. Huma adattati għal xenarji li jeħtieġu kontroll preċiż tal-fluss tal-midja jew regolamentazzjoni, u jaħdmu eċċezzjonalment tajjeb f'ambjenti ta' pressjoni baxxa- sa medja-u pressjoni-għola.

Karatteristiċi tal-Valv Globe Elettriku
1. Il-valv tal-globu elettriku huwa ddisinjat u manifatturat skont standards, bi struttura raġonevoli, siġillar affidabbli, prestazzjoni eċċellenti, u dehra attraenti.
2. Id-diska tal-valv u l-uċuħ tas-siġillar tas-sedil huma magħmula minn liga bbażata fuq il-ħadid-jew liga tal-matriċi tal-kobalt Stellite permezz tal-iwweldjar, li jipprovdu reżistenza eċċellenti għall-ilbies, reżistenza għat-temperatura għolja, reżistenza għall-korrużjoni, reżistenza għall-grif, u ħajja twila ta 'servizz.
3. Iċ-zokk tal-valv jgħaddi minn trattament ta 'tifi u ttemprar u nitriding tal-wiċċ, li jirriżulta f'reżistenza tajba għall-korrużjoni u reżistenza għall-grif.
4. Is-siġill ta 'wara juża konnessjoni bil-kamin jew huwa magħmul minn azzar inossidabbli awstenitiku permezz tal-iwweldjar, u jiżgura siġillar affidabbli. Is-sostituzzjoni tal-ippakkjar tista 'titwettaq b'mod konvenjenti u malajr mingħajr ma titwaqqaf is-sistema.
5. Mgħammar b'attwatur elettriku b'ħafna -dawran tas-serje DZW, li fih akkomodazzjoni żgħira, piż ħafif, u funzjonalità sħiħa. Jista 'jintuża ma' kompjuter remot u jista 'jkun ukoll mgħammar b'attwatur elettriku skont ir-rekwiżiti tal-utent.
