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. Ama-valve 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.
