Isahluko 1 - Iyini ivalvu yebhola?
I-valve yebhola ye-PVC noma ye-polyvinyl chloride iyi-valve yepulasitiki evalayo enebhola elijikelezayo elinembobo evimba ukugeleza koketshezi ngokuphendula ibhola ikota yokujika. Zihlala isikhathi eside kakhulu, zingabizi kakhulu futhi zingasetshenziswa ukulawula ukugeleza kwamanzi, umoya, amakhemikhali agqwalisayo, ama-asidi kanye nezisekelo. Ama-valve ebhola ye-PVC anokumelana okuhle kakhulu nokushisa okuphansi kanye nokucindezela, kodwa anamandla aphansi okusebenza. Njengawo wonke ama-valve ebhola, ama-valve ebhola ye-PVC ayayeka ukugeleza ngokujikelezisa ibhola ngama-90°.

Ingaphakathi levalvu yebhola ye-PVC ibhola elijikelezayo, elibizwa ngokuthi ibhola elijikelezayo. Isiqu esiphezulu sebhola yindlela ephendula ibhola, engenziwa ngesandla noma ngokuzenzakalelayo, kuye ngomklamo wevalvu. Ivalvu iyavuleka lapho isibambo sihambisana nepayipi futhi ivala lapho isibambo siqonde ngqo epayipini.

I-valve yebhola ye-PVC

Amavalvu ebhola e-PVC enziwe ngepulasitiki engashi futhi angamelana namazinga okushisa asukela ku--14°C kuya ku--140°C. Asebenza ngezinjongo eziningi ezifanayo namavalvu ebhola endabuko, kodwa alula, aqinile, kulula ukuwafaka, futhi ayakwazi ukuzivumelanisa nezinhlelo zokusebenza ezahlukahlukene.

Isahluko 2 - Izinhlobo zamavalvu ebhola le-PVC
Izinhlobo ezahlukene zamavalvu ebhola e-PVC zenzelwe ukuhlangabezana nezicelo ezithile. Zihlukaniswe ngenani lama-port, uhlobo lwesihlalo, ukuhlanganiswa komzimba, izindlela zebhola kanye nosayizi we-bore. Isici esinqumayo ekukhetheni uhlobo lwevalvu yebhola ukusetshenziswa, okunqunywa yingcindezi, usayizi, izinga lokushisa, inani lama-port adingekayo, ukufakwa kokugcina kanye nokucushwa.

Amavalvu ebhola le-PVC enziwe nge-vinyl, into e-thermoplastic eshintsha izakhiwo zomzimba lapho ishiswa noma ipholiswa. Njengazo zonke i-thermoplastics, i-PVC iyipulasitiki enobungani nemvelo engancibilikiswa futhi ibunjwe kabusha izikhathi eziningi. Ngaphezu kokusetshenziswa ekwenziweni kwamavalvu ebhola le-PVC, i-PVC isetshenziswa kabanzi ekukhiqizweni kwamapayipi.

ivalvu ezenzakalelayo
I-valve yebhola ye-PVC ezenzakalelayo ingaba ngezindlela ezimbili noma ezintathu. Ine-actuator yomoya noma kagesi engalawulwa ngesandla ngesilawuli kude noma ibe nomshini wesipilingi. Ama-valve ebhola ye-PVC asebenza ngokwawo aklanyelwe ukuqala ibhola elisevalvini ukuthi livuleke noma livale ukuze likhulule noma limise ukugeleza kwemidiya futhi angasetshenziswa ezinhlobonhlobo zemidiya kusukela emanzini kuya kugesi namafutha.

Hlola ivalvu
Amavalvu okuhlola ibhola le-PVC asetshenziswa lapho ukugeleza emuva kungalimaza uhlelo noma kubangele ukungcoliswa kohlelo lokuhlunga kanye nokupompa. Ayivalvu yebhola ezenzakalelayo ekhulula ingcindezi ohlelweni. Amavalvu okuhlola e-PVC ayizinsika ezivala ingcindezi lapho ingcindezi ifinyelela ezingeni elithile. Asetshenziswa ekucubungulweni kwamakhemikhali, ekuhlanzweni kwamanzi kanye nasezinqubweni zokupholisa ngamakhemikhali. Ngokungafani namavalvu avamile e-PVC, amavalvu okuhlola awanaso isiqu noma isibambo futhi alula kakhulu ekwakheni.

I-Flanged PVC Ball Valve
Isici esiyingqayizivele se-valve yebhola ye-PVC e-flanged yindlela yayo yokuxhuma, okungukuthi, i-flange. Igeleza kakhulu ngoba imvamisa iyi-bore egcwele. Ama-valve ebhola ye-PVC e-flanged ayatholakala anezimbobo ezimbili, ezintathu noma ezine, alula futhi kulula ukuwafaka. Ubukhulu be-flange buyahlukahluka kuye ngokucindezela okusetshenzisiwe. Ama-valve ebhola e-PVC e-flanged asebenzisa i-glue noma ama-bolts ane-gaskets.

I-PVC Ball Valve Entantayo
Nge-valve yebhola ye-PVC entantayo, ibhola lilenga oketshezini futhi libanjwe yisihlalo se-valve esicindezelwe. Umgodi unamathele phezulu kwebhola, futhi ukujika kwesine kwesibambo kunikeza indawo ebushelelezi kusukela ekuvulekeni kuya ekuvalekeni. Njengoba ibhola liphenduka, licindezelwa esihlalweni salo, livimba ukugeleza. Ibhola liyantanta emzimbeni we-valve, yingakho igama le-valve libizwa.

I-Full Bore PVC Ball Valve
Kuma-valve ebhola e-PVC agcwele imbobo, imbobo ebholeni ifana nobubanzi bepayipi. Ngenxa yokuthi imbobo evalvini ilingana nepayipi, uma ivalvu ivuliwe, ukugeleza kwe-medium akuvinjelwe futhi akukho ukwehla kwengcindezi kwanoma yiluphi uhlobo. Ama-valve ebhola e-PVC agcwele imbobo abhekwa njengama-valve okubuyisela izinhlelo ezidinga ukwehla kwengcindezi okuphansi kanye nama-coefficients okugeleza okuphezulu.

Ivalvu Esetshenziswa Ngesandla
Phakathi kwezinhlobo ezahlukene zamavalvu ebhola le-PVC, ukusebenza ngesandla kuyindlela elula futhi elula kakhulu ukuyisebenzisa. Vula ivalvu yebhola le-PVC enezindlela ezimbili ngokuhambisa isibambo sihambisana nepayipi. Ukuze uvale ivalvu, hambisa isibambo siqonde ngqo epayipini. Ukuvula noma ukuvala ivalvu kudinga ukuphenduka kwekota kwesibambo kunoma iyiphi indlela.
