Xa kuziwa ekulawuleni ukuhamba kwamanzi kwiinkqubo zemibhobho, iinketho ezimbini ezidumileyo yivalve yeplagi kunye neivalve yebhola. Zombini iintlobo zeevalvu zisebenza ngeenjongo ezifanayo kodwa zineempawu ezahlukileyo ezenza ukuba zilungele usetyenziso olwahlukileyo. Ukuqonda umahluko phakathi kwevalve yeplagi kunye nevalve yebhola kunokukunceda wenze isigqibo esinolwazi kwiimfuno zakho ezithile.
Uyilo lweValufa kunye nokusebenza
A ivalve yeplagiifaka iplagi eyicylindrical okanye enetapered engena kwisitulo esihambelanayo ngaphakathi kumzimba wevalvu. Iplagi inokujikeleziswa ukuze ivule okanye ivale indlela yokuhamba, ivumela ukusebenza ngokukhawuleza nokulula. Olu yilo lunenzuzo ngokukodwa kwizicelo ezifuna ulawulo rhoqo oluvaliweyo.
Ngokuchaseneyo, ivalve yebhola isebenzisa idiski engqukuva (ibhola) enemingxuma embindini wayo. Xa ivalve ivuliwe, umngxuma uhambelana nendlela yokuhamba, uvumela ulwelo ukuba ludlule. Xa ivaliwe, ibhola iyajikeleza ukuvalela ukuhamba. Iivalvu zebhola ziyaziwa ngobuchule bazo bokutywina kwaye zihlala zisetyenziswa kwizicelo apho uthintelo lokuvuza lubalulekile.
Iimpawu zeValve Flow
Zombini iiplagi kunye neevalve zebhola zibonelela ngolawulo oluhle kakhulu lokuhamba, kodwa ziyahluka kwiimpawu zazo zokuhamba. Iivalvu zokuplaga zibonelela ngesantya sokuhamba ngomda othe kratya, uzenza zilungele usetyenziso lwe-throttling. Nangona kunjalo, banokufumana amaconsi aphezulu oxinzelelo xa kuthelekiswa neevalve zebhola, ezibonelela ngokuhamba okungathintelekiyo xa zivuleke ngokupheleleyo.
Izicelo zeValve
Iivalvu zeplagi ziqhele ukusetyenziswa kwizicelo ezibandakanya i-slurries, iigesi, kunye nolwelo, ngakumbi kwishishini leoli negesi. Iivalve zebhola, kwelinye icala, zisetyenziswa ngokubanzi kwiinkqubo zokubonelela ngamanzi, ukusetyenzwa kweekhemikhali, kunye nezicelo ze-HVAC ngenxa yokuthembeka kunye nokulula kokusetyenziswa.
Ukuqukumbela
Isishwankathelo, ukhetho phakathi kwevalve yeplagi kunye nevalve yebhola kuxhomekeke kwiimfuno ezithile zesicelo sakho. Ngelixa zombini iivalvu zibonelela ngeenzuzo ezizodwa, ukuqonda umahluko wazo kuyilo, ukusebenza, kunye neempawu zokuqukuqela kuya kukunceda ukhethe ivalve elungileyo ukuze usebenze kakuhle.
