Indlela yokukhetha okulungilei-hydraulic butterfly valve?
I-Hydraulic butterfly valve iyi-valve yokulawula uketshezi evamile, esetshenziswa kabanzi ku-petroleum, amakhemikhali, amandla kagesi, ukuhlinzekwa kwamanzi nezinye izimboni. Ukukhetha i-valve ye-butterfly eyi-hydraulic efanele kungathuthukisa ukusebenza kahle futhi kunciphise izindleko. Lesi sihloko sizochaza indlela yokukhetha i-valve butterfly efanelekile ye-hydraulic.
Okokuqala, qonda uhlelo lwamapayipi
Ngaphambi kokukhetha i-valve ye-butterfly eyi-hydraulic efanele, kuyadingeka ukuqonda imvelo nezici zesistimu yamapayipi. Okokuqala, kuyadingeka ukuqonda ingcindezi, izinga lokushisa, ukugeleza kanye neminye imingcele yepayipi ukuze ukhethe impahla ye-valve efanele, usayizi nohlobo lwe-valve.
2. Thola i-fluid medium
Ukukhethwa kwe-hydraulic butterfly valve kufanele futhi kucabangele uhlobo lwe-fluid medium, njengokuthi inokugqwala, i-viscous, izinga lokushisa kanye neminye imingcele. Imithombo ye-fluid ehlukene izoba nezidingo ezihlukene ezintweni kanye nokuvala i-valve, ngakho-ke kuyadingeka ukukhetha ngokuvumelana nesimo sangempela.
Okwesithathu, khetha impahla ye-valve efanele
Impahla ye-hydraulic butterfly valve ibandakanya ikakhulukazi umzimba we-valve, ipheya yokuvala kanye noxhumo lwepayipi. Ngokuvamile esetshenziswa insimbi, cast iron, insimbi engagqwali nezinye izinto. Ukukhetha impahla ye-valve efanele kungaqinisekisa ukuzinza nokuqina kwe-valve endaweni ethile yokusebenza, ngaleyo ndlela kwandise impilo yesevisi ye-valve.
4. Khetha uhlobo lwevalvu olufanele
Kunezinhlobo ezintathu zama-valve uvemvane we-hydraulic: i-eccentric eyodwa, i-double eccentric kanye ne-triple eccentric. I-valve ye-eccentric eyodwa efanelekile ingcindezi ephansi, i-low flow fluid medium; I-valve ye-eccentric ephindwe kabili ilungele ukucindezela okuphakathi nendawo nokuphezulu kanye nokugeleza okuphezulu; Ama-valve amathathu e-eccentric afanele ukucindezela okuphezulu, izinga lokushisa eliphezulu kanye nemidiya edlayo. Ngakho-ke, ukukhethwa kohlobo olufanele lwe-hydraulic butterfly valve kungakhethwa ngokuvumelana nezidingo zangempela zendawo yokusebenza.
5, thola izidingo ze-inertia nokugeleza
Lapho ukhetha i-valve ye-butterfly ye-hydraulic, kuyadingeka ukucacisa izidingo zayo ze-inertia nokugeleza. Ngokuvumelana ne-inertia nokugeleza kwe-valve, ithuluzi lokulawula elifanelekile kanye nedivayisi yokusiza ukucindezela kuyakhethwa ukuze kuqinisekiswe ukuzinza nokuphepha kwesistimu yamapayipi.
Okungenhla kuyizici ezimbalwa zokukhetha i-valve ye-butterfly ye-hydraulic efanelekile. Yiqiniso, lapho ukhetha i-valve ye-butterfly ye-hydraulic, ezinye izici zidinga ukucatshangelwa, njengokuqina, izidingo zenqubo, njalonjalo. Ngokuvamile, ukukhethwa okulungile kwama-valve e-butterfly e-hydraulic kungaqinisekisa ukusebenza kahle nokuzinzile kwesistimu yamapayipi futhi kunciphise izindleko.
