Isahluko 1 - Yini i-valve yebhola?
I-PVC noma i-polyvinyl chloride ball valve iyivalvu yepulasitiki evuliwe enebhola elijikelezayo elinembobo evimba ukugeleza koketshezi ngokuphendula ibhola ikota.Zihlala isikhathi eside ngokwedlulele, azibizi kakhulu futhi zingasetshenziswa ukulawula ukuhamba kwamanzi, umoya, amakhemikhali abolayo, ama-asidi nezisekelo.Ama-valve ebhola e-PVC anokushisa okuphansi okuhle kakhulu nokumelana nokucindezela, kodwa amandla aphansi emishini.Njengawo wonke ama-valve ebhola, ama-valve ebhola e-PVC amisa ukugeleza ngokuzungezisa ibhola ngo-90°.

Umnyombo we-valve yebhola ye-PVC iyibhola elijikelezayo, elibizwa ngokuthi ibhola elijikelezayo.Isiqu esiphezulu sebhola siyindlela ephendula ibhola, engenziwa ngesandla noma ngokuzenzakalelayo, kuye ngokuthi i-valve yakhiwe kanjani.I-valve ivula lapho isibambo sihambisana nepayipi futhi ivale lapho isibambo sibhekene nepayipi.

Amavalvu ebhola e-PVC enziwe ngepulasitiki engashi futhi angakwazi ukumelana namazinga okushisa asuka ku -14°C kuya ku-140°C.Afeza izinjongo eziningi ezifanayo namavalvu ebhola endabuko, nokho angasindi, aminyene, afakwa kalula, futhi ayakwazi ukuzivumelanisa nezinhlelo eziningi ezahlukene.

Isahluko 2 - Izinhlobo ze-PVC Ball Valves
Izinhlobo ezahlukene zamavalvu ebhola e-PVC zenzelwe ukuhlangabezana nezinhlelo zokusebenza ezithile.Ahlukaniswa ngenani lamachweba, uhlobo lwesihlalo, ukuhlangana komzimba, amaphaseji amabhola kanye nosayizi webhore.Isici esinqumayo ekukhetheni uhlobo lwe-valve yebhola uhlelo lokusebenza, olunqunywa ukucindezela, ubukhulu, izinga lokushisa, inani lamachweba adingekayo, ukufakwa kokugcina nokucushwa.

Ama-valve ebhola e-PVC enziwe nge-vinyl, impahla ye-thermoplastic eshintsha izakhiwo zomzimba lapho ishisa noma ipholile.Njengawo wonke ama-thermoplastics, i-PVC iyipulasitiki evumelana nemvelo engancibilika futhi ibunjwe kabusha izikhathi eziningi.Ngaphezu kokusetshenziswa ekukhiqizeni ama-valve ebhola e-PVC, i-PVC ibuye isetshenziswe kabanzi ekukhiqizeni amapayipi.

i-valve ezenzakalelayo
I-valve yebhola ye-PVC ezenzakalelayo ingaba nezindlela ezimbili noma ezintathu.Bane-actuator yomoya noma kagesi engalawulwa ngesandla ngesilawuli kude noma ibe nendlela yasentwasahlobo.Ama-valve ebhola e-PVC azenzelayo aklanyelwe ukucupha ibhola ku-valve ukuthi livuleke noma livale ukuze likhulule noma limise ukugeleza kwemidiya futhi lingasetshenziselwa imidiya ehlukahlukene kusukela emanzini kuya kugesi namafutha.

Hlola i-valve
Ama-valve okuhlola amabhola e-PVC asetshenziswa lapho ukugeleza emuva kungalimaza uhlelo noma kubangele ukungcoliswa kwesistimu yokuhlunga nokupompa.Ziyi-valve yebhola ezenzakalelayo ekhulula ingcindezi ohlelweni.Ama-valve okuhlola e-PVC angama-trunnions avala ngokucindezela lapho ingcindezi ifinyelela ezingeni elithile.Zisetshenziselwa ukucubungula amakhemikhali, ukwelashwa kwamanzi kanye nezinqubo zokupholisa ngamakhemikhali.Ngokungafani nama-valve e-PVC avamile, ama-valve okuhlola awanazo isiqu noma isibambo futhi alula ekwakhiweni.

I-Flanged PVC Ball Valve
Isici esiyingqayizivele se-valve yebhola ye-PVC ene-flanged yindlela yayo yokuxhuma, okungukuthi, i-flange.Zinokugeleza okuphezulu ngoba ngokuvamile zigcwele ibhore.Ama-valve ebhola e-PVC ane-Flanged ayatholakala namachweba amabili, amathathu noma amane, alula futhi kulula ukuwafaka.Ubukhulu be-flange buyahlukahluka kuye ngokuthi ingcindezi esetshenzisiwe.Ama-valve ebhola e-PVC ane-flanged asebenzisa iglue enamathelayo noma amabhawodi anama-gaskets.

I-PVC Ball Valve entantayo
Nge-valve yebhola ye-PVC entantayo, ibhola limiswa oketshezini futhi libanjwe isihlalo sevalve esicindezelwe.I-shaft inamathiselwe phezulu kwebhola, futhi ukujika kwekota yesibambo kunikeza ukuma okushelelezi ukusuka ekuvulekeni kuya kokuvaliwe.Njengoba ibhola liphenduka, licindezelwa esihlalweni salo, limise ukugeleza.Ibhola lintanta emzimbeni wevalvu, yingakho igama levalvu.

I-Bore PVC Ball Valve ephelele
Ukuze uthole ama-valve ebhola e-PVC agcwele, ukuvuleka kwebhola kufana nobubanzi bepayipi.Ngenxa yokuthi imbobo ye-valve ilingana nepayipi, lapho i-valve ivulekile, ukugeleza kwe-medium akuvinjelwe futhi akukho kwehla kwengcindezi kwanoma yiluphi uhlobo.Amavalvu ebhola e-PVC agcwele abhekwa njengama-valve okubuyisela amasistimu adinga ukwehla kokucindezela okuphansi kanye nama-coefficients okugeleza okuphezulu.

I-Valve Esebenza Mathupha
Phakathi kwezinhlobo ezahlukene zama-valve ebhola le-PVC, ukusebenza okwenziwa ngesandla kulula kakhulu futhi kulula kakhulu ukukusebenzisa.Vula i-valve yebhola ye-PVC enezinhlangothi ezimbili ngokuhambisa isibambo ngokuhambisana nepayipi.Ukuvala i-valve, hambisa isibambo se-perpendicular kumbhobho.Ukuvula noma ukuvala i-valve kudinga ukuphenduka kwekota yesibambo kunoma iyiphi indlela.
