Ivalvu yebhola yangaphandle yePPR-1067-DN32x25
ipharamitha
Ivalvu yamanzi sisixhobo esiphambili esisetyenziswa kakhulu kwiinkqubo zemibhobho yamanzi, esisetyenziselwa ukulawula, ukulawula okanye ukucima ukuhamba kwamanzi. Sifanelekile kwiindawo ezahlukeneyo zokusetyenziswa kunye neemeko, kuquka ezoshishino, ezorhwebo, kunye nekhaya.
Izinto ze-PPR esizisebenzisayo zinozinzo oluhle kakhulu lweekhemikhali kwaye zinokumelana nokuwohloka kweekhemikhali ezahlukeneyo, kuquka izinto ze-asidi kunye ne-alkali, ngaloo ndlela zandisa ubomi benkonzo yevalvu. Ngenxa yobunzima obukhulu bezinto ze-PPR, ivalvu yebhola ayinakugugiswa ngexesha lokusetyenziswa, iqinisekisa ukusebenza kakuhle kokutywina kunye nolawulo lokuhamba kwamanzi. Ivalvu yebhola ingavulwa okanye ivalwe ngokujikeleza ama-90 degrees, kwaye isiphumo sokutywina sigqibelele, siqinisekisa ukusebenza kakuhle kwenkqubo yepayipi. I-spool yevalvu yebhola ingajikeleziswa kwii-engile ezahlukeneyo ngokweemfuno, ukuze kufezekiswe ukulungiswa ngokuchanekileyo kwesantya sokuhamba kwamanzi kunye nokuhlangabezana neemfuno zeemeko ezahlukeneyo. Izinto ze-PPR zinokumelana namaqondo obushushu aphezulu, ngoko ke ivalvu yebhola ifanelekile kwiinkqubo zepayipi kwiindawo ezinobushushu obuphezulu ukuqinisekisa ukusebenza okuqhelekileyo kwenkqubo.
Indlela yokudibanisa ivalvu yebhola ye-PPR idla ngokuba kukudibanisa ngemisonto, kwaye inkqubo yokufakela ilula kwaye iyakhawuleza, ngaphandle kwezixhobo namanyathelo anzima. Ukusebenza kwevalvu yebhola kufuneka kujikeleze kuphela ii-degrees ezingama-90, ukusebenza kulula kwaye konga abasebenzi, kufanelekile ukusebenza rhoqo. Le valve yebhola ifanelekile ukubonelelwa ngamanzi, ukufudumeza, umoya opholileyo, iikhemikhali kunye nezinye iinkqubo zemibhobho ukuhlangabezana neemfuno zamacandelo ahlukeneyo. Inokudityaniswa nezixhobo ezahlukeneyo zepayipi, ezifana nepayipi ye-PPR, ipayipi ye-PE, njl.njl., nto leyo ephucula ukuhambelana kunye nokuguquguquka kwenkqubo. Uyilo lwayo lwesakhiwo lufanelekile, kulula ukuluqhekeza nokucoca, kwaye lulungele abasebenzisi ukwenza imisebenzi yokulungisa yemihla ngemihla.
