Incazelo yomkhiqizo

Idizayini yevalvu ku-EN 593, BS5155, DIN3354

I-Flange ku-EN 1092, ASME B16.5, ASME B16.1, AWWA C207

Ubude bobuso nobuso kuya ku-EN 558-1 / ISO 5752 uchungechunge 14 noma uchungechunge 13

Ukushisela insimbi engagqwali kanye nesihlalo somzimba esiqediwe siqinisekisa ukugqwala nokugqoka ubuso besihlalo obungazweli.

Idizayini yediski enephrofayili esezingeni eliphansi eqinisekisiwe iqinisekiswe ukuhlaziya kwezinto ezinomkhawulo iqinisekisa amandla aphezulu kanye nokumelana nokugeleza okuphansi

Ngokusebenzisa i-seal gasket eklanywe endaweni ehlangene phakathi kwe-shaft bearing ne-disc, indandatho ephindwe kabili ye-O ekuphetheni kwe-shaft kanye namehlo e-disc avaliwe, enza isimo sokusebenza esomile se-shaft kanye ne-shaft seal ukugwema ukugqwala kusuka ku-service medium.

I-Anti-blow out shaft design.

Ukuxhuma kwe-disc kuya ku-shaft ngokusebenzisa iphinikhodi noma ukhiye (uyazikhethela).

Ukuzigcoba ngokwakho ngethusi noma insimbi engagqwali efakwe ulayini we-PTFE kunciphisa ukungqubuzana kwe-shaft kanye ne-torque yokusebenza, ama-bearings agcina i-disc phakathi futhi avimbele ukunyakaza kwe-axial;

Izindandatho eziningi ze-O ohlelweni lokuvala uphawu lwe-shaft zingavimbela ukuphuma nokungcola.Amaringi e-O akugland yokupakisha kanye nekhava ye-shaft ingashintshwa kalula ngaphandle kokukhipha ivalvu epayipini.

Ifanele izimo zesevisi ye-vacuum ephelele.

Indandatho yotywino eqinile enephrofayili ivikelwa kudiski ngendandatho yesibambi namabhawudi, futhi iqinisekisa ukusebenza okuthembekile kokuvala lapho kuqondiswa kabili.Iringi yophawu ingashintshwa noma ishintshwe kalula esizeni.Awudingi amathuluzi akhethekile.

Idivayisi yokukhiya yangaphandle izohlinzekwa emikhawulweni yeshafi engashayeli, ukuze igiya likwazi ukukhishwa nevalvu esele isebenza endaweni evuliwe noma evaliwe.

Isebenza nge-gearbox + handwheel kanye ne-ISO 5210 top flange okufanele ihlanganiswe ne-actuator kagesi, uma kudingeka ngokuhamba kwesikhathi.

I-valve yangaphandle nangaphakathi ehlanganiswe i-epoxy eboshwe ngogqinsi lwama-250micron (i-coating/lining ehlukile iyatholakala njengesicelo esikhethekile) kanye nekhodi yombala RAL5005/5015/5017.

Ifanele izinhlelo zokusebenza ezibandakanya isevisi ye-throttling kanye nezinhlelo zokusebenza ezidinga ukusebenza kwe-valve ngemva kwesikhathi eside sokungasebenzi.
