I-Dbb Ball Valve Double Block kanye ne-Bleed Ball Valve China Manufacture
Iyini i-valve yebhola ye-DBB?
I-Double Block kanye ne-Bleed Ball Valveiyi-valve yebhola eklanyelwe ekhethekile.
mayelana ne-Double block kanye nesistimu ye-valve yokopha, kunezincazelo ezimbili nge-API6D ne-OSHA.
I-API 6D ichaza i-aI-Double Block kanye ne-Bleed ValveIsistimu “njenge-valve eyodwa enezindawo zokuhlala ezimbili, lapho endaweni evaliwe, ihlinzeka ngophawu ngokumelene nokucindezela okuvela kuzo zombili iziphetho ze-valve ngendlela yokuthengisa/yokopha imbobo phakathi kwezindawo zokuhlala.”
I-OSHA ichaza i-aI-Double Block kanye ne-Bleed ValveUhlelo “njengokuvalwa kolayini, ipayipi, noma ipayipi ngokuvala nokukhiya noma ukumaka amavalvu amabili asemgqeni nangokuvula nokukhiya noma ukumaka i-drain noma i-valve yokukhipha umoya emgqeni ophakathi kwamavalvu amabili avaliwe”.
iI-NORTECH ibhulokhi ephindwe kabili kanye ne-valve yebhola elophayakhelwengokuhlanganisa ama-valve amabili abe ngumzimba owodwa, idizayini enama-valve angamawele inciphisa isisindo kanye nezindlela zokuvuza ezingase zibe khona ngenkathi ihlangabezana nezimfuneko ze-OSHA zokuvimba kabili nokopha.
Izici eziyinhloko ze-valve yebhola ye-DBB
Iyunithi EyodwaI-DBB Ball Valveinikeza block kabili futhi ukopha valve eyodwa.Lesi sitayela singakwazi ukuhlukanisa amapayipi ezinhlangothini zombili zevalvu ukuze kukhishwe/kophe imbobo yevalvu phakathi kwezihlalo.
I-DBB Ball Valveiyinhlanganisela ye-block/ivalve yokuhlukanisa eyodwa noma ngaphezulu, imvamisa amavalvu ebhola, kanye namavalvu awophayo noma amaningi, ngokuvamile amabhola noma inaliti.Inhloso yesistimu ye-valve ye-block and bleed iwukuhlukanisa noma ukuvimba ukugeleza koketshezi ohlelweni ukuze uketshezi oluvela phezulu lungafinyeleli kwezinye izingxenye zesistimu ezingaphansi komfula.Lokhu kusiza onjiniyela ukuba bakhiphe igazi noma bakhiphe noma bakhiphe uketshezi olusele ohlelweni ohlangothini olungezansi komfula ukuze benze uhlobo oluthile lomsebenzi (ukulungisa/ukulungisa/ukushintsha), amasampula, ukuphambukisa ukugeleza, imijovo yamakhemikhali, ukuhlola ubuqotho bokuvuza njll. .
Ukusebenzisa iyunithi eyodwa yebhulokhi ephindwe kabili kanye nesistimu ye-valve yokopha ngokumelene nama-valve ahlukene amathathu konga isikhathi sokufakwa, isisindo ohlelweni lwamapayipi, nesikhala.Lo mklamo nawo unezinzuzo zokusebenza,
- Zimbalwa kakhulu izindlela zokuvuza ezingase zibe khona ngaphakathi kwebhulokhi ephindwe kabili nengxenye yokopha kwepayipi.
- Ama-valve agcwele imbobo ene-orifice yokugeleza engaphazamiseki futhi anomfutho ongelutho wokwehla kuyo yonke iyunithi.
- Amapayipi lapho la ma-valve efakwe khona nawo angafakwa ngaphandle kwezinkinga.
Ukucaciswa kobuchwepheshe kwevalve yebhola ye-DBB
Umbukiso Womkhiqizo:I-DBB yebhola valve
Ukusetshenziswa kwe-valve yebhola ye-DBB
I-valve yebhola ye-DBBasetshenziswa kakhulu embonini kawoyela negesi, kodwa angasiza nakwezinye izimboni eziningi.Ngokuvamile isetshenziswa lapho ukopha i-valve cavity kudingeka, lapho amapayipi adinga ukuhlukaniswa ukuze alungiswe, noma kunoma yisiphi salezi zimo:
- Vimbela ukungcoliswa komkhiqizo.
- Khipha okokusebenza enkonzweni ukuze kuhlanzwe noma kulungiswe.
- Ukulinganisa imitha.
- Hlukanisa izinsimbi ezifana nezinkomba zokucindezela kanye nama-lever gauge.
- Inqubo eyinhloko umusi.
- Vala futhi ukhiphe izinsimbi zokulinganisa ingcindezi.
