Ezi zikhetho zokwenza ngokwezifiso iivalve zebhola ze-UPVC zibe lukhetho oluguquguqukayo kuyo nayiphi na iprojekthi. Ngokusebenza ngokusondeleyo nabavelisi abathembekileyo, ndinokuqinisekisa ukuba iivalve zihlangabezana neemfuno ezisebenzayo kunye nobuhle.
Iivalvu zebhola ze-UPVC zibonelela ngesisombululo esithembekileyo nesiguquguqukayo solawulo lolwelo lwamashishini. Ukuqina kwazo kunye nokumelana neekhemikhali kubenza bafaneleke ukuphatha uluhlu olubanzi lwamanzi, kubandakanywa neekhemikhali ezonakalisayo. Ndiyibonile indlela ukusebenza kwabo okugudileyo kunye neemfuno ezincinci zokugcinwa zinciphisa ixesha lokuphumla kunye neendleko zokusebenza. Ezi zivalo zikwalungelelaniswa neenjongo zozinzo ngokuphinda zisetyenziswe kwaye zilungele ukusingqongileyo.
Ukusebenzisana nabavelisi bevalvu yebhola ye-upvc ethembekileyo iqinisekisa ukufikelela kwiimveliso ezikumgangatho ophezulu ezihlangabezana nemigangatho yoshishino. Aba bavelisi bazisa ubuchwephesha bobugcisa kwaye babambelele kwizatifikethi ezingqongqo, ziqinisekisa iivalvu eziqinileyo nezihlala ixesha elide. Ngokukhetha umboneleli ofanelekileyo, ndinokuzithemba ngokuzithemba iimfuno zeprojekthi yoshishino ngelixa ndiqinisekisa ukusebenza kakuhle kunye nokuthembeka.
FAQ
1. Yintoni eyenza iivalvu zebhola ze-UPVC zahluke kwiivalvu zentsimbi?
Iivalvu zebhola ze-UPVC zixhathisa ukubola kunye nomonakalo weekhemikhali, ngokungafaniyo neevalvu zetsimbi. Uyilo lwabo olukhaphukhaphu lwenza lula ukufakela kunye nokunciphisa iindleko zokuthumela ngenqanawa. Ndikwazifumana zineendleko ezithe kratya kwaye kulula ukuzigcina, zizenza zilungele iiprojekthi zemizi-mveliso ezifuna ukuqina nokusebenza kakuhle.
2. Ngaba iivalvu zebhola ze-UPVC zinokuphatha iinkqubo zoxinzelelo oluphezulu?
Ewe, iivalve zebhola ze-UPVC zinokubamba uxinzelelo ukuya kuthi ga kwi-PN16 (16 bar). Ndihlala ndiqinisekisa ukuba i-valve yoxinzelelo lwe-valve ihambelana neemfuno zenkqubo yokugcina ukusebenza kakuhle kunye nokhuseleko kwizicelo zoxinzelelo oluphezulu.
3. Ngaba iivalvu zebhola ze-UPVC zihambelana nokusingqongileyo?
Iivalvu zebhola ze-UPVC zenziwe ngezinto ezingenatyhefu, ezinokuphinda zisetyenziswe. Ubomi babo obude kunye nokugcinwa okuncinci kunciphisa inkunkuma. Ndibacebisa kwiiprojekthi ezibeka phambili uzinzo kunye noxanduva lokusingqongileyo.
4. Ndikhetha njani ubungakanani obufanelekileyo beprojekthi yam?
Ndifanisa ubungakanani bevalve kwidayamitha yombhobho ukuqinisekisa ukuhamba okuhambelanayo. Kwizicelo zamashishini,ubukhulu obufana ne-140MM okanye i-200MMziyafumaneka. Ukubonisana nabavelisi kundinceda ndiqinisekise eyona ifaneleka kakhulu kwiimfuno zokusebenza ezithile.
5. Ngaba iivalvu zebhola ze-UPVC zinokwenziwa ngokwezifiso kwizicelo ezithile?
Ewe, iinketho zokwenza ngokwezifiso ziquka ubungakanani, iintlobo zoqhagamshelo, kunye nezixhobo zokutywina. Ndihlala ndisebenza nabavelisi ukulungelelanisa iivalve kwiimfuno ezizodwa zeprojekthi, ukuqinisekisa ukuhambelana kunye nokusebenza kakuhle.
