Kwiinkqubo zokulawula imibhobho kunye nolwelo, ukukhethwa kwamacandelo afana nemibhobho yePVC kunyeIivalvu zebhola zePVCkubalulekile ukuqinisekisa ukusebenza kakuhle kunye nokuphila ixesha elide. Nangona kunjalo, ngemigangatho emininzi kunye nezixhobo, ukukhetha amacandelo ahambelanayo afanelekileyo kunokuba ngumngeni. Eli nqaku liza kukukhokela ekukhetheni imibhobho ye-PVC efanelekileyo kunye neevalvu zebhola ukuqinisekisa ukuhambelana kunye nokusebenza kakuhle.
Ukuqonda iMibhobho yePVC kunye neeValufa zeBhola
I-PVC (i-Polyvinyl Chloride) yinto esetyenziswa ngokubanzi kwiplastiki kwimibhobho ngenxa yokuqina kwayo, ukuxhathisa ukubola, kunye nokusebenza kakuhle kweendleko. Imibhobho ye-PVC ifumaneka kwiidayamitha ezahlukeneyo kunye noxinzelelo loxinzelelo lwezicelo ezahlukeneyo ukusuka kwimibhobho yokuhlala ukuya kwiinkqubo zoshishino. Kwelinye icala,Iivalvu zebhola zePVCzibalulekile ekulawuleni ukuhamba kolwelo kunye neegesi ngaphakathi kwemibhobho. Banikezela ngomatshini othembekileyo wokuvala kwaye bayaziwa ngokukhululeka kwabo ekusebenzeni.
Ukubaluleka kweenqobo zokulinganisa
Xa ukhetha iipayipi zePVC kunye neevalve zebhola, into yokuqala ekufuneka uyiqwalasele kukuqinisekisa ukuba ihlangabezana nemigangatho efanelekileyo. Imimandla eyahlukeneyo kunye namashishini anokuba nemigangatho ethile yobungakanani bombhobho kunye nevalve, ukulinganiswa koxinzelelo, kunye neenkcukacha zezinto eziphathekayo. Ngokomzekelo, eUnited States, i-American National Standards Institute (ANSI) kunye ne-American Society for Testing and Materials (ASTM) ibeka izikhokelo kwiimveliso zePVC. Ngokwahlukileyo koko, amanye amazwe asenokulandela imigangatho eyahlukileyo, efana ne-International Organization for Standardization (ISO).
Xa ukhetha amacandelo ahambelanayo, soloko uqinisekisa ukuba iipayipi zePVC kunyeiivalve zebholaukuhlangabezana nemigangatho efanayo. Oku kuqinisekisa ukuba zifakwe ngokuchanekileyo kwaye zisebenza ngokufanelekileyo ngaphandle kokuvuza okanye ukungasebenzi kakuhle. Ngalo lonke ixesha ujonge ukucaciswa kwemveliso kunye neziqinisekiso ukuze uqinisekise ukuba ziyahlangabezana nemigangatho efanelekileyo.
Ukuhambelana kwezinto
Ngelixa i-PVC lukhetho oludumileyo lwemibhobho kunye neevalvu, ayisiyiyo kuphela into ekhoyo. Kwezinye iimeko, unokuhlangabezana neevalve zebhola ezenziwe ngezinto ezahlukeneyo, ezifana nobhedu okanye insimbi engenasici. Xa ukhetha i-valve yebhola kwipayipi ye-PVC, kubalulekile ukuqwalasela ukuhambelana kwezinto. Ukusebenzisa iivalvu ezenziwe ngezinye izinto kunokubangela iingxaki ezifana ne-galvanic corrosion, enokuthi ibeke esichengeni ukuthembeka kwenkqubo.
Ukuze usebenze ngokugqibeleleyo, kuyacetyiswa ukubaIivalvu zebhola zePVCisetyenziswe ngombhobho wePVC. Le ndibaniselwano iqinisekisa ukuba omabini amacandelo ayanda kwaye avumelane ngemilinganiselo efanayo, ukunciphisa uxinzelelo kunye nokunciphisa umngcipheko wokuvuza okunokwenzeka. Ukuba ivalve eyenziwe ngenye into kufuneka isetyenziswe, qiniseka ukuba yenzelwe ukusetyenziswa kunye nombhobho wePVC kwaye usebenzise izixhobo ezifanelekileyo ukuqinisekisa uqhagamshelwano olukhuselekileyo.
UBUKHULU KUNYE NOXINEZELO LWERAYITHI
Enye into ephambili ekukhetheni ukulinganisa imibhobho yePVC kunye neevalvu zebhola ubukhulu kunye noxinzelelo loxinzelelo. Ububanzi bamacandelo omabini kufuneka bufane ukuze kuqinisekiswe umdlalo ogqibeleleyo. Ukongezelela, ukulinganiswa koxinzelelo lwe-valve yebhola kufuneka kuhlangane okanye kudlule ukunyanzeliswa kombhobho wePVC ukukhusela ukungaphumeleli phantsi kweemeko zoxinzelelo oluphezulu. Ngalo lonke ixesha bhekisa kwizikhokelo zomenzi ukumisela ubungakanani obufanelekileyo kunye noxinzelelo loxinzelelo kwisicelo sakho esithile.
Ukukhetha imibhobho ehambelana nePVC kunyeiivalve zebholakubalulekile ekwakheni inkqubo yemibhobho ethembekileyo nesebenzayo. Ngokuqwalasela izinto ezifana nemigangatho, ukuhambelana kwezinto, ubungakanani, kunye nomlinganiselo woxinzelelo, unokuqinisekisa ukuba amacandelo aya kusebenza ngokuvisisana. Ukuthatha ixesha lokukhetha amacandelo ahambelanayo afanelekileyo akuyi kuphucula ukusebenza kwenkqubo kuphela, kodwa nokwandisa ubomi bayo, ekugqibeleni kukugcinele ixesha kunye nemali.
