I-valve yebhola entantayo ye-ISO5211 yezimboni esezingeni eliphezulu Umkhiqizi waseChina
Iyini ivalvu yebhola entantayo?
A ivalvu yebhola elintantayoUma i-valve inebhola layo elintantayo (elingaqiniswanga yi-trunnion) ngaphakathi komzimba we-valve, iyashelela iye ohlangothini olungezansi bese icindezela ngokuqinile esihlalweni ngaphansi kwengcindezi ephakathi ukuqinisekisa ukuthembeka kokuvala. I-valve yebhola elintantayo inesakhiwo esilula, ukusebenza kahle kokuvala kodwa izinto zesihlalo ziyadingeka ukuze zimelane nomthwalo womsebenzi njengoba ingcindezi yokuvala ivuliwe yindandatho yesihlalo. Ngenxa yokungatholakali kwezinto zesihlalo ezisebenza kahle kakhulu, i-valve yebhola elintantayo isetshenziswa kakhulu ekusetshenzisweni kwengcindezi ephakathi noma ephansi.
Uma ivalvu ibekwe lapho imbobo iqondiswe khona ngendlela efanayo nepayipi, isendaweni evulekile, futhi uketshezi lungadlula phansi komfula. I-NORTECHI-valve yebhola entantayo iwumkhiqizo omusha owenziwe ngokuguqulwa kwevalvu evamile kanye nokwamukelwa kwendinganiso yamazwe ngamazwe esesikhathini.
Izici eziyinhloko ze-NORTECH ISO5211 floating ball valve?
1. Umklamo Wezihlalo Ezikhethekile
samukela umklamo wesakhiwo sendandatho yokuvala eguquguqukayo yevalvu yebhola elintantayo. Uma ingcindezi ephakathi iphansi, indawo yokuxhumana yendandatho yokuvala nebhola incane. Kuzonciphisa ukungqubuzana kanye ne-torque yokusebenza futhi kuqinisekise ukuqina ngesikhathi esifanayo. Lapho ingcindezi ephakathi ikhuliswa, indawo yokuxhumana yendandatho yokuvala nebhola iba nkulu kanye nokuguquguquka kwendandatho yokuvala, ukuze indandatho yokuvala ikwazi ukubekezelela umthelela ophakathi ophezulu ngaphandle kokulimala.

2. Umklamo Wesakhiwo Ongashiswa Ngumlilo
Uma kwenzeka umlilo ngesikhathi kusetshenziswa i-valve, indandatho yesihlalo eyenziwe nge-PTFE noma ezinye izinto ezingezona ezensimbi izobola noma yonakale ngaphansi kokushisa okuphezulu futhi kuzoholela ekuvuza okukhulu koketshezi, kuyingozi kakhulu endaweni evuthayo noma eqhumayo. Indandatho yokuvala engashisi umlilo ibekwe phakathi kwebhola nesihlalo ukuze ngemva kokuba isihlalo se-valve sishisiwe, indawo yokuvala izosunduza ibhola ngokushesha iye endandatho yokuvala yensimbi engezansi ukuze yakhe isakhiwo sokuvala insimbi esisekelayo kuya kwensimbi esingalawula ngempumelelo ukuvuza kwe-valve. Ngaphezu kwalokho, i-gasket yokuvala i-flange ephakathi, engaqinisekisa ukuvalwa ngisho nangaphansi kokushisa okuphezulu. Umklamo wesakhiwo esingashisi umlilo se-floating ball valve uhambisana nezidingo ku-APl607, APl6FA, BS 6755 kanye nezinye izindinganiso.

3. Isakhiwo Esilwa Nokungaguquguquki
I-valve yebhola yakhelwe ngesakhiwo esingaguquki kanye nedivayisi yokukhipha ugesi ongaguquki ukuze yakhe ngqo isiteshi esingaguquki phakathi kwebhola nomzimba ngokusebenzisa isiqu ukuze ikhiphe ugesi ongaguquki okhiqizwa ukungqubuzana kwebhola nesihlalo, igweme umlilo noma ukuqhuma okungase kubangelwe ukukhazimula okungaguquki nokuqinisekisa ukuphepha kohlelo.

4. Ukuvalwa Okuthembekile Kwesiqu Sevalvu
Ngaphezu kwalokho, ukuze kugwenywe ukuvuza ngemva kokushiswa kwe-stem packing uma kwenzeka umlilo, i-thrust bearing ibekwa endaweni lapho i-stem stem packing kanye nomzimba zithintana khona ukuze kwakheke isihlalo sokuvala esingemuva. Amandla okuvala e-reverse seal azokhula ngokuya ngokwanda kwengcindezi ephakathi, ukuze kuqinisekiswe ukuvalwa kwe-stem okuthembekile ngaphansi kwengcindezi ehlukahlukene, kuvinjelwe ukuvuza futhi kugweme ukusabalala kwengozi. Isakhiwo sokuvala i-V packing senzelwe i-stem, i-V type packing ingashintsha ngempumelelo amandla okucindezela kanye namandla aphakathi e-gland abe amandla okuvala e-stem. Ngokwezidingo zabasebenzisi, indlela yokucindezela i-disc spring packing elayishwe nge-disk spring ingasetshenziswa ukwenza ukuvalwa kwe-stem packing kuthembeke kakhudlwana.

5. Ukuvimbela Ukukhiya Nokungasebenzi Kahle
I-valve yebhola ephathwayo ingakhiywa nge-lock endaweni evulekile noma evalwe ngokuphelele. Ingcezu yokubeka evulekile nevalwe engu-90° enembobo yokukhiya yenzelwe ukugwema ukusebenza kabi kwe-valve okubangelwa ama-opreator angagunyaziwe, futhi ingavimbela nokuvulwa noma ukuvalwa kwe-valve, noma ezinye izingozi ezibangelwa ukudlidliza kwephayiphi noma izinto ezingalindelekile. Isebenza kahle kakhulu ikakhulukazi kumapayipi kawoyela avuthayo naqhumayo, amakhemikhali kanye nokusebenza kwezokwelapha noma amapayipi asensimini. Ingxenye esekhanda lesiqu efakwe nesibambo isebenzisa umklamo oyisicaba.
