● Usanifu na Utengenezaji Unaendana na BS5163
● Vipimo vya Flange Inapatana na EN1092-2 PN10,PN16,PN25
● Vipimo vya Uso kwa Uso Vipatane na BS5163
● Majaribio Yanalingana na BS5163、EN12266-1
● Hali ya kuendesha gari: gurudumu la mkono, kifuniko cha mraba
Ufungaji na matengenezo ya valves ya lango inapaswa kuzingatia mambo yafuatayo:
Gurudumu la mkono, mpini na utaratibu wa maambukizi hairuhusiwi kutumika kwa kuinua, na mgongano ni marufuku madhubuti.
Vali za lango mara mbili zitawekwa wima (yaani, shina la valvu liko katika nafasi ya wima na gurudumu la mkono liko juu).
Valve ya lango yenye valve ya bypass itafungua valve ya bypass kabla ya kufungua (ili kusawazisha tofauti ya shinikizo kwenye mlango na mlango na kupunguza nguvu ya ufunguzi).
Valve ya lango yenye utaratibu wa maambukizi itawekwa kulingana na masharti ya mwongozo wa uendeshaji wa bidhaa.
Ikiwa valve mara nyingi hufunguliwa na kufungwa, lubricate angalau mara moja kwa mwezi.
Kulingana na hali ya kuendesha ya valve, imegawanywa katika valve ya lango la umeme, valve ya lango la nyumatiki na valve ya lango la mwongozo.
