I-Double Block kanye ne-Bleed Ball Valve
Iyini i-Double block kanye nevalve yebhola elopha?
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 kulayini 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-Double block kanye ne-valve yebhola elopha
I-Double Block kanye ne-Bleed 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. .
Iyunithi EyodwaI-Double Block kanye ne-Bleed Valveinikeza block kabili futhi ukopha valve eyodwa.Lesi sitayela singakwazi ukuhlukanisa amapayipi ezinhlangothini zombili zevalvu ukuze kukhishwe/kophe imbobo yevalvu phakathi kwezihlalo.
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 mavalvu efakwe khona nawo angafakwa ngaphandle kwezinkinga.
- Zonke izingxenye ze-valve zibekwe endaweni eyodwa, isikhala esidingekayo sokufakwa sincipha kakhulu ngaleyo ndlela kukhulula indawo yezinye izingcezu zemishini ebalulekile.
- Kudingeka izikhathi ezimfushane zokudonsa amanzi.
Ukucaciswa kobuchwepheshe kwe-Double block kanye nevalve yebhola elopha
Umbukiso Womkhiqizo:
Ukusetshenziswa kwe-double block kanye nama-valve ebhola elopha
Ama-valve ama-block kabili awophaasetshenziswa 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.
- Isevisi yoketshezi eduze kwemigwaqo yamanzi noma komasipala.
- Ukudlulisa nokugcina.
- Umjovo wamakhemikhali kanye nesampula.
- Hlukanisa izinsimbi ezifana nezinkomba zokucindezela kanye nama-lever gauge.
- Inqubo eyinhloko umusi.
- Vala futhi ukhiphe izinsimbi zokulinganisa ingcindezi.
