I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvinyl chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenzeni izinsimbi zamavalvu.

I-PVC (i-polyvinyl chloride) ne-UPVC (i-polyvinyl chloride engafakwanga ipulasitiki) yizinto ezisetshenziswa kakhulu ekwenziweni kokufakwa kwamavalvu. Lezi zinto zepulasitiki zaziwa ngokuqina kwazo, ukumelana nokugqwala, kanye nokuthengeka kwazo, okuzenza zibe ukukhetha okudumile kwezinhlelo zokusebenza ezihlukahlukene, okuhlanganisa amapayipi, ukuchelela, nezinqubo zezimboni.

Olunye uhlobo oluvamile lokufakwa kwe-valve olwenziwa nge-PVC noma i-UPVC i-valve engezansi ye-PVC, eklanyelwe ukulawula ukugeleza koketshezi futhi ivimbele ukubuya emuva. Isimiso sokusebenza se-valve engezansi ye-PVC sisekelwe endleleni elula kodwa ephumelelayo. Lapho uketshezi lugeleza ohlangothini olufunayo, i-valve iyavuleka ukuze kudlule uketshezi. Kodwa-ke, uma kukhona ukuhlehla kokugeleza, i-valve ivala ngokuzenzakalelayo ukuze kuvinjwe ukugeleza koketshezi emuva.

Izingxenye ezibalulekile ze-valve engezansi ye-PVC zifaka umzimba we-valve, ovame ukwenziwa nge-PVC noma i-UPVC, kanye nendlela yokuvala efana nerabha noma i-silicone gasket. Lapho umfutho we-fluid uphakeme ohlangothini lwe-valve lokungena, uphusha umshini wokuvala, okwenza i-valve ivuleke futhi ivumele uketshezi ukuba ludlule. Ngokuphambene, lapho ingcindezi ohlangothini lwe-outlet iba phezulu, indlela yokuvala icindezelwa ngokumelene nesihlalo se-valve, ivale ngokuphumelelayo ukugeleza.

Ukusetshenziswa kwe-PVC noma i-UPVC ekwakhiweni kwama-valve aphansi kunikeza izinzuzo eziningana. Lezi zinto zilula, okwenza ama-valve aphathe futhi afakwe kalula. Ukwengeza, i-PVC ne-UPVC amelana nokugqwala, ukuwohloka kwamakhemikhali, nokukhula kwezinto eziphilayo, okuwenza afanelekele ukusetshenziswa ezindaweni ezihlukahlukene, okuhlanganisa izimo ezibolayo nezilimazayo.

Ngaphezu kwalokho, amavalvu aphansi e-PVC kanye ne-UPVC ayindlela engabizi kakhulu kumavalvu ensimbi endabuko, anikeza ukusebenza okufanayo ngezindleko eziphansi. Izindawo zabo ezibushelelezi zangaphakathi ziphinde zehlise ukwehla kwengcindezi kanye nesiyaluyalu, kube nomthelela ekugelezeni kahle koketshezi.

Sengiphetha, i-PVC ne-UPVC yizinto ezisebenza ngezindlela eziningi zokukhiqiza izifakelo zamavalvu, okuhlanganisa namavalvu aphansi. Isimiso sokusebenza se-valve engezansi ye-PVC sisekelwe endleleni ethembekile yokucindezela kwamanzi ukulawula ukugeleza nokuvimbela ukubuyela emuva. Ngokuhlala isikhathi eside, ukumelana nokugqwala, kanye nokusebenza kahle kwezindleko, amavalvu aphansi e-PVC nawe-UPVC ayizingxenye ezibalulekile ezinhlelweni ezihlukahlukene zokulawula uketshezi.
