I-valve yebhola yepulasitiki isetshenziswa kakhulu ukusika noma ukuxhuma i-medium epayipini, kodwa futhi isetshenziselwa ukulawula nokulawula uketshezi.I-valve yebhola inezinzuzo eziningi, njengokumelana noketshezi oluphansi, isisindo esilula, ukubukeka okuhlangene nokuhle, ukumelana nokugqwala, uhla olubanzi lwezinhlelo zokusebenza, izinto ezihlanzekile nezingezona ezinobuthi, ukumelana nokugqoka, ukuqaqa kalula, ukugcinwa kalula.Kungani inezinzuzo eziningi kangaka?Leli yiphuzu esilihlolayo namuhla - impahla.
Izinto ezihlukene zinezici ezihlukene, futhi uma zenziwa i-valve yebhola lepulasitiki, i-valve yebhola lepulasitiki izonikezwa izici zento ngokwayo.Namuhla, kunezinto eziningi ezisetshenziselwa ukwenza ama-valve ebhola epulasitiki, njenge-UPVC, i-RPP, i-PVDF, i-PPH, i-CPVC, njll.
I-UPVC ivamise ukubizwa nge-hard PVC, okuyi-amorphous thermoplastic resin eyenziwe nge-vinyl chloride monomer ngokusabela kwe-polymerization kanye nezithasiselo ezithile (njengama-stabilizer, izinto zokuthambisa, izigcwalisi, njll.) Amavalvu ebhola e-UPVC awawona kuphela i-acid-, i-alkali- nokugqwala- ukumelana, kodwa futhi ube namandla aphezulu emishini futhi uhlangabezane nezindinganiso kazwelonke zokukhucululwa kwendle emanzini okuphuza.Ukusebenza kokuvalwa komkhiqizo kuhle kakhulu, kusetshenziswa kakhulu ekwakhiweni komphakathi, amakhemikhali, ezemithi, i-petrochemical, i-metallurgy, ezolimo, ukunisela, i-aquaculture kanye nolunye uhlelo lomgwaqo olusemthethweni lwamanzi.-10℃ kuya ku-70℃ ibanga lokushisa.
I-RPP iyimpahla ye-polypropylene eqinisiwe.Ama-valve ebhola ahlanganiswe futhi alolongwa ngezingxenye zomjovo we-RPP anokumelana nokugqwala okuhle kakhulu, impilo yesevisi eyandisiwe, ukujikeleza okuvumelana nezimo nokusebenzisa kalula.-20℃ kuya ku-90℃ ibanga lokushisa.
I-Polyvinylidene fluoride, i-PVDF ngamafuphi, iyi-thermoplastic fluoropolymer engasasebenzi kakhulu.Kuyinto evimbela ilangabi, imelana nokukhathala futhi akulula ukuphuka, i-anti-wear, izakhiwo ezinhle zokuzigcoba, izinto ezinhle zokuvikela.I-valve yebhola ye-PVDF inokusimama okuhle kwamakhemikhali, ukumelana namakhemikhali kanye nokuzinza kokumelana nokushisa.Ingasetshenziswa isikhathi eside ezingeni lokushisa -40℃ kuya ku-140℃, futhi ingamelana nawo wonke usawoti, i-asidi, i-alkali, i-hydrocarbon enuka kamnandi, i-halogen neminye imidiya ngaphandle kwezinyibilikisi ezinamandla.
I-CPVC wuhlobo olusha lwepulasitiki yobunjiniyela enohlelo oluthembisayo.Umkhiqizo umhlophe noma uphuzi ngokukhanyayo awunambitheki, awunaphunga, ama-granules angenabuthi noma impushana.I-cpvc ball valve noma ngabe i-asidi, i-alkali, usawoti, i-chlorine, imvelo ye-oxidation, evezwe emoyeni, ingcwatshwe enhlabathini egqwalayo, ngisho naku-95 ℃ izinga lokushisa eliphezulu, ngaphakathi nangaphandle ngeke igle, isaqinile futhi ithembekile njengasekuqaleni. ukufakwa.
