IMVAVVU YEBHOLA ELIntantayo
Okujwayelekile
Idizayini nezinga Lokukhiqiza: API 6D, ASME B16.34, API 608, BS 5351
Ubuso nobuso:ASME B16.10,API 6D,DIN 3202,BSEN 558
Usayizi Wokuxhuma we-Flange: ASME B16.5, BSEN 1092
Ukuhlola nokuhlola: API598,API6D
1. Umklamo Wezihlalo Ezikhethekile
I-valve yebhola elintantayo yamukela ukwakheka kwesakhiwo sendandatho yophawu oluguquguqukayo. Lapho ingcindezi ephakathi nendawo iphansi, indawo yokuxhumana yendandatho yophawu nebhola incane. Ngakho-ke isilinganiso esiphezulu sokubekwa uphawu kwakheka endaweni lapho indandatho yophawu kanye nokuxhumana kwebhola ukuze kuqinisekiswe ukubekwa uphawu okuthembekile. Lapho ingcindezi ephakathi nendawo iphakeme, indawo yokuthintana ye-seal nebhola iba nkulu kanye nokuguqulwa okunwebekayo kwendandatho yophawu, ngakho-ke indandatho yophawu ingabekezelela ukuphonswa okuphakathi okuphezulu ngaphandle kokulimala.
2. Idizayini Yesakhiwo Sokuvikela Umlilo
Uma kwenzeka umlilo ngesikhathi kusetshenziswa i-valve, indandatho yesihlalo eyenziwe nge-PTFE noma ezinye izinto ezingezona ezensimbi izobola noma yonakaliswe ngaphansi kwezinga lokushisa eliphezulu futhi ibangele ukuvuza okuphezulu. Indandatho yophawu olungashi ibekwe phakathi kwebhola nesihlalo ukuze emva kokushiswa kwesihlalo sevalvu, okuphakathi kuzophusha ibhola ngokushesha libheke ezansi nomfula okuyindandatho yophawu lwensimbi ukuze yenze insimbi eyisiza eya esakhiweni sokuvala sensimbi, esingalawula ngempumelelo ukuvuza kwevalvu. Ngaphezu kwalokho, i-gasket yokuvala i-flange ephakathi yenziwe nge-gasket yesilonda sensimbi, engaqinisekisa ukuvalwa ngisho nangaphansi kokushisa okuphezulu. Idizayini yesakhiwo esingashi wevalvu yebhola elintantayo ihambisana nezidingo eziku-API 607, spi 6FA, BS 6755 namanye amazinga.
3. Ukuvalwa Okuthembekile Kwesiqu Se-Valve
Isiqu sinikezwa ihlombe ngaphansi kwalo ukuze lingashaywa yi-medium ngisho nangaphansi kwezimo ezimbi kakhulu ezifana nokukhuphuka kwengcindezi engavamile ngaphakathi kwe-valve cavity, ukwehluleka kwepuleti ye-gland nokunye. Ngaphezu kwalokho, ukugwema ukuvuza ngemva ukupakishwa kwe-stem kuyasha uma kuba nomlilo, i-thrust bear ibekwe endaweni lapho ihlombe le-stem kanye nokuthintana komzimba ukuze kwakhe isihlalo sokuvala uphawu. Amandla okuvalwa kwe-reverse seal azokwenyuka ngokuya ngokukhuphuka kwengcindezi ephakathi nendawo, ukuze kuqinisekiswe ukuvalwa kwesiqu okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjwe ukuvuza nokugwema ukusabalala kwengozi.
Isiqu samukela isakhiwo sokupakisha sohlobo lwe-V. Ukupakishwa kohlobo lwe-V kungashintsha ngempumelelo amandla okucindezelayo namandla aphakathi nendawo edlala abe amandla okuvalwa kwesiqu.
Ngokwezidingo zomsebenzisi, indlela yokucindezela yokupakisha elayishiwe ye-disc ingamukelwa ukwenza ukubekwa uphawu kokupakishwa kwesiqu kuthembeke kakhudlwana.
4. Isakhiwo esiphikisana ne-static
I-valve yebhola ihlinzekwa ngesakhiwo esimelene ne-static futhi yamukela idivayisi yokukhipha ugesi omile ukuze yakhe ngokuqondile umzila omile phakathi kwebhola nomzimba noma yakhe ishaneli emile phakathi kwebhola nomzimba ngesiqu, ukuze ikhiphe ugesi omile okhiqizwayo. ngenxa yokungqubuzana ngesikhathi kuvulwa futhi kuvalwa ibhola nesihlalo epayipini, ukugwema umlilo noma ukuqhuma okungase kudalwe inhlansi enganyakazi kanye nokuqinisekisa ukuphepha kohlelo.
5. Ukukhiya kanye Nokuvimbela Ukungasebenzi kahle
I-valve yebhola yamanuwali ingakhiywa ngengidi uma isendaweni evulekile noma evala ngokugcwele. Isiqephu sokuma esivulekile nesivalekile esingu-90° esinembobo yokukhiya siklanyelwe ukugwema ukusebenza kabi kwama-valve okubangelwa ukusebenza kwezibambo ezingasebenzisi, futhi singavimbela ukuvuleka noma ukuvala kwama-valve, noma ezinye izingozi ezibangelwa ukudlidliza kwepayipi noma izici ezingalindelekile. Isebenza kakhulu ikakhulukazi ezicini ezivuthayo. Isebenza kahle kakhulu ikakhulukazi kuwoyela ovuthayo naqhumayo, amapayipi asebenza ngamakhemikhali nawezokwelapha noma amashubhu asensimini. Ingxenye esekhanda lesiqu efakwe nesibambo yamukela umklamo oyisicaba. Lapho i-valve ivuliwe, isibambo sihambisana nepayipi, ukuze izinkomba zokuvula nokuvala ze-valve ziqinisekiswe ukuthi azikho iphutha.
I-Newsway Valves Materials
Umzimba we-valve ye-NSW nezinto zokunquma zinganikezwa ngohlobo lwe-Forged nohlobo Lokusakaza. Eduze kwempahla yensimbi engagqwali neyekhabhoni, siphinde sikhiqize amavalvu ngezinto ezikhethekile ezifana ne-titanium, ama-nickel alloys, HASTELLOY®*, INCOLOY®, MONEL®, Alloy 20, super-duplex, alloy resistant corrosion and urea grade materials.
