Owona msebenzi wam wakutsha nje ibikukuqinisekisa ukuba yeyiphi ivalve yebhola ekufuneka isetyenziswe ukutshintsha ivalve yebhola endala eshedini.Emva kokujonga izinto ezikhethiweyo ezahlukeneyo kunye nokwazi ukuba baya kudibanisa kumbhobho wePVC, ngaphandle kwamathandabuzo ndikhangele iIvalve yebhola yePVC.

Kukho iintlobo ezintathu ezahlukeneyo zeevalvu zebhola zePVC, nganye ineenzuzo zayo.Ezi ntlobo zintathu zi-compact, zidibene kunye ne-CPVC.Kule bhlog, siza kuphonononga ukuba yintoni eyenza uhlobo ngalunye lube lodwa kunye neengenelo ezinalo.

Ivalve yeBhola yePVC eQinisekileyo
Ivalve yebhola ehlangeneyo ye-PVC yakhiwe kusetyenziswa indlela yokubumba-kwindawo echazwe kwiblogi yethu yeeNdlela zoKwakha.Ukusebenzisa le ndlela ikhethekileyo yokubumba iplastiki ejikeleze ibhola kunye ne-stem assembly ibonelela ngeenzuzo ezininzi.Kusetyenziswa ibhola egcweleyo, kodwa akukho mthungo kwivalve njengoko kufuneka yongezwe kwelinye icala.Oku kwenza ivalve yomelele kwaye iqine ngakumbi ngaphandle kokuthintela ukuhamba.Ivalve yebhola ehlangeneyo ye-PVC ifumaneka kwi-IPS enentambo (Ubungakanani boMbhobho weIron) kunye noqhagamshelo lokutyibilika kwiShedyuli ye-40 kunye ne-80 yombhobho.

Njengevalve eyomeleleyo kwaye eyomeleleyo, zifanelekile kwiintlobo ezahlukeneyo zokusetyenziswa kwamanzi.Xa ukhangele ivalve yezoqoqosho, ivalve yebhola ye-PVC edibeneyo lukhetho oluhle kakhulu.

Alliance PVC Ball Valve
Uyilo lweManyano lubandakanya iimanyano kuqhagamshelo olunye okanye zombini ukuvumela ukugcinwa komgca wevalve ngaphandle kokuyiqhawula kumbhobho.Akukho zixhobo zokulondoloza ezikhethekileyo ezifunekayo, njengoko isibambo sinee-square lugs ezimbini ezivumela ukuba isibambo sisetyenziswe njenge-wrench adjustable.Xa ukugcinwa kwevalve kuyadingeka, i-threaded retaining ring ingalungiswa okanye isuswe ngokusebenzisa isiphatho ukulungelelanisa isitywina okanye indawo ye-O-ring.

Xa inkqubo iphantsi koxinzelelo, xa umanyano luthe lwachithwa, imanyano evaliweyo iya kuthintela ibhola ukuba ingakhutshelwa ngaphandle, kwaye umanyano lwezoqoqosho aluyi kuba nanto yokuthintela ibhola ukuba ingakhutshelwa ngaphandle.

Ingaba uyazi?Iivalvu zebhola ezibambeneyo nezidityanisiweyo zePVC ziyafumaneka kwiShedyuli yama-40 kunye neenkqubo zeShedyuli yama-80 njengoko ezi zilinganiso zibhekisa kubunzima bodonga lombhobho.Iivalvu zebhola zePVCzilinganiswe ngoxinzelelo kunokuba ubukhulu bodonga, zivumeleke ukuba zilungele iShedyuli 40 kunye neShedyuli ye-80 yemibhobho.Ububanzi bangaphandle beetyhubhu ezimbini buhlala bufana, kwaye ububanzi bangaphakathi buyancipha njengoko ubuninzi bodonga bukhula.Ngokubanzi, umbhobho weShedyuli 40 umhlophe kwaye umbhobho weShedyuli 80 ungwevu, kodwa ivalve yombala inokusetyenziswa kuyo nayiphi na inkqubo.

Ivalve yebhola yeCPVC
I-CPVC (i-chlorinated polyvinyl chloride) iivalve zebhola zakhiwe ngendlela efanayo ne-compact valves, kunye neentlukwano ezimbini eziphambili;imilinganiselo yobushushu kunye noqhagamshelwano.Iivalvu zebhola zeCPVCzenziwe kwi-PVC eneklorini, eyenza ukuba bakwazi ukumelana nobushushu obuphezulu.Ezi zivalo zenzelwe ukusetyenziswa kwamanzi ashushu ukuya kuthi ga kwi-180 ° F.

Ukudibanisa kwi-valve yebhola ye-CPVC yi-CTS (ubungakanani betyhubhu yobhedu), onobukhulu obuncinci bombhobho kune-IPS.I-CTS yenzelwe iinkqubo zamanzi ashushu nabandayo, nangona isetyenziswa ikakhulu kwimizila yamanzi ashushu.

Iivalvu zebhola ze-CPVC zinemibala e-beige ukunceda ukuzohlula kwiivalvu zebhola ezimhlophe eziqhelekileyo.Ezi zivalo zinezinga eliphezulu lobushushu kwaye zilungele ukufudumeza izicelo ezifana nezifudumezi zamanzi.

Iivalve zebhola ze-PVC lukhetho oluhle kakhulu kwiinkqubo ezahlukeneyo zemibhobho, kunye nokugcinwa okuhlukeneyo kunye nokushisa okuphezulu.Iivalve zebhola zikwafumaneka ngobhedu kunye nensimbi engenasici, ngoko ke kukho ivalve yebhola kuyo yonke isicelo esifuna ukulawula ukuhamba kwamanzi.
