I-API 6D/API 608 Ukuphonswa/Ukwakhiwa Okuphezulu Kwe-Bw Floating/Trunnion Dbb Manual/Electrical/Pneumatic Cryogenic Eccentric Semi-Ball Valve

Incazelo emfushane:

II-valve yebhola ye-DBB trunnion, yakhelwe ukufaka esikhundleni sendlela eyinkimbinkimbi yokuxhumeka kwama-valve amaningi epayipini. Isebenzisa umklamo wama-valve amabili. Ngokuhlanganisa ama-valve amabili abe umzimba owodwa, umklamo wama-valve amabili unciphisa isisindo kanye nezindlela zokuvuza ezingaba khona ngenkathi ihlangabezana nezidingo ze-OSHA zokuvinjwa okuphindwe kabili kanye nokopha.

Usayizi: 1/2 - 16 intshi.
Ingcindezi: Isigaba 150 LB – 2500 LB.
Izinto: Insimbi Yekhabhoni, Insimbi Engagqwali, Insimbi Yengxubevange, njll.
ifakelwe i-floating noma i-trunnion, ngenhloso ye-DBB ne-DIB.

Iyini ivalvu yebhola le-DBB trunnion?

I-valve yebhola le-DBB trunnioniyivalvu yebhola eklanyelwe ngokukhethekile.

Ngokuqondene nohlelo lwe-Double block kanye ne-bleed valve, kunezincazelo ezimbili nge-API6D kanye ne-OSHA.

I-OSHA ichaza i-I-valve yebhola ye-DBB trunnionUhlelo “njengokuvalwa komugqa, ipayipi, noma ipayipi ngokuvala nokukhiya noma ukumaka amavalvu amabili angaphakathi kanye nokuvula nokukhiya noma ukumaka ivalvu yokudonsa noma yokungenisa umoya emgqeni ophakathi kwamavalvu amabili avaliwe”.

iI-valve yebhola ye-NORTECH DBB trunnionyakhelweNgokuhlanganisa ama-valve amabili abe umzimba owodwa, umklamo wama-valve amabili unciphisa isisindo kanye nezindlela zokuvuza ezingaba khona ngenkathi kuhlangatshezwana nezidingo ze-OSHA zokuvinjwa kabili kanye nokuphuma kwegazi.

I-API 6D ichaza uhlelo lwe-valve yebhola le-DBB trunnion njenge-"valve eyodwa enezindawo zokuhlala ezimbili, lapho ivaliwe, enikeza uphawu lokumelana nokucindezela okuvela kuzo zombili izinhlangothi zevalve ngendlela yokudlulisa/ukukhipha igazi emgodini ophakathi kwezindawo zokuhlala."

Izici eziyinhloko ze-valve yebhola le-DBB trunnion

Iyunithi EyodwaI-valve yebhola ye-DBB trunnion inikeza ibhlogo eliphindwe kabili futhi liphuma igazi ku-valve eyodwa. Lesi sitayela singahlukanisa amapayipi kuzo zombili izinhlangothi ze-valve ukuze kukhishwe umoya/kuphume igazi ku-valve cavity phakathi kwezihlalo.

Ukusebenzisa iyunithi eyodwa enebhulokhi eliphindwe kabili kanye nohlelo lwevalvu eliphuma igazi uma kuqhathaniswa namavalvu amathathu ahlukene kusindisa isikhathi sokufakwa, isisindo ohlelweni lwamapayipi, kanye nesikhala. Lo mklamo unezinzuzo zokusebenza,

Kunezindlela ezimbalwa kakhulu zokuvuza ezingaba khona ngaphakathi kwesigaba samabhulokhi amabili kanye nesigaba sokuphuma kwegazi sepayipi.
Zonke izingxenye zamavalvu zigcinwe kuyunithi eyodwa, isikhala esidingekayo sokufakwa sincishiswa kakhulu ngaleyo ndlela sikhulula isikhala seminye imishini ebalulekile.
Kudingeka izikhathi ezimfushane zokukhipha amanzi.

I-valve yebhola ye-DBB trunnion kuyinhlanganisela yamavalvu ebhulokhi/okuhlukanisa eyodwa noma ngaphezulu, ngokuvamile amavalvu ebhola, kanye namavalvu e-bleed/vent eyodwa noma ngaphezulu, ngokuvamile amavalvu ebhola noma enaliti. Inhloso yesistimu ye-block kanye ne-bleed valve ukuhlukanisa noma ukuvimba ukugeleza koketshezi ohlelweni ukuze uketshezi oluvela phezulu lungafiki kwezinye izingxenye zesistimu ezingezansi. Lokhu kwenza onjiniyela bakwazi ukuphuma noma ukukhipha noma ukukhipha uketshezi olusele ohlelweni ohlangothini olungezansi ukuze benze uhlobo oluthile lomsebenzi (ukulungiswa/ukulungiswa/ukufakwa esikhundleni), ukusampula, ukuphambuka kokugeleza, ukujova ngamakhemikhali, ukuhlola ubuqotho bokuvuza njll.

Ukusetshenziswa kwe-valve yebhola le-DBB trunnion

Amavalvu ebhola le-DBB trunnionZisetshenziswa kakhulu embonini kawoyela negesi, kodwa futhi zingaba usizo kwezinye izimboni eziningi. Ngokuvamile zisetshenziswa lapho kudingeka khona ukopha emgodini we-valve, lapho amapayipi edinga ukuhlukaniswa ukuze kulungiswe, noma kunoma yiziphi ezinye izimo:
