Iyini ivalvu yomhlaba?
Izingxenye zokuvula nokuvala zevalvu yomhlaba ziyidiski emise okwepulaki, indawo yokuvala iyisicaba noma iyindilinga, futhi idiski ihamba ngomugqa oqondile eceleni komugqa ophakathi woketshezi. Ifomu lokunyakaza kwesiqu, kukhona uhlobo lwenduku yokuphakamisa (ukuphakamisa isiqu, isondo lesandla aliphakamisi), kukhona uhlobo lwenduku yokuphakamisa ejikelezayo (ukuphakamisa isondo lesandla nesiqu kuzungeza ndawonye, i-nut emzimbeni wevalvu). Ivalvu yomhlaba ifaneleka kuphela ekuvulekeni okugcwele nokuvaliwe ngokuphelele, ayivunyelwe ukulungiswa nokugoba.
Ama-valve e-globe angama-valve avaliwe ngenkani, ngakho-ke uma i-valve ivaliwe, ingcindezi kumele ifakwe kudiski ukuze ukuphoqa indawo yokuvala ingavuzi. Lapho i-medium evela ngaphansi kwe-disc ingena ku-valve yesithupha, ukumelana nokunqoba amandla okusebenza amandla okungqubuzana kwesiqu kanye nokupakisha kanye nokucindezelwa okukhiqizwa yingcindezi ye-medium, amandla okuvala i-valve makhulu kunamandla okuvula i-valve, ngakho-ke ububanzi besiqu kufanele bube bukhulu, ngaphandle kwalokho ukwehluleka kokugoba kwesiqu phezulu kuzokwenzeka. Eminyakeni yamuva nje, selokhu kwavela i-valve yokuvala, ukugeleza kwe-medium ye-globe valve kuyashintshwa kusuka phezulu kwe-valve kuya ekamelweni le-valve, bese kuthi ngaphansi kwesenzo sengcindezi ephakathi, amandla okuvala i-valve abe mancane, futhi amandla okuvula i-valve abe makhulu, futhi ububanzi besiqu bungancishiswa ngokufanele. Ngesikhathi esifanayo, ngaphansi kwesenzo se-medium, lolu hlobo lwe-valve nalo luqinile kakhulu. I-valve yaseShayina "ezintathu kuya" ibeke ukuthi isiqondiso sokugeleza kwe-globe valve siphezulu kuya phansi.
Uma i-globe valve ivuliwe, ukuphakama kokuvula kwe-valve disc kungu-25% kuya ku-30% wobubanzi obujwayelekile, futhi ukugeleza kufinyelele esiphezulu, okubonisa ukuthi i-valve ifinyelele endaweni evulekile ngokuphelele. Ngakho-ke, indawo evulekile ephelele ye-globe valve kufanele inqunywe ngokushaywa kwe-valve disc.
I-Globe valve ingahlukaniswa ibe yi: i-globe valve, i-threaded stem globe valve, i-threaded stem globe valve, i-straight-through globe valve, i-Angle globe valve, i-three-way globe valve, i-straight-flow globe valve, i-plunger globe valve, i-needle globe valve.
INortech ingenye yabakhiqizi bama-valve ezimboni abahamba phambili eShayina abanesitifiketi sekhwalithi se-ISO9001.
Imikhiqizo emikhulu:I-Butterfly Valve,I-Ball Valve,I-Valve yeSango,Hlola i-Valve,I-Globe Vavlve,Izihlungi ze-Y,I-Acurator kagesi,Ama-Acurators omoya.
