Amaphuzu ayinhloko okukhethwa kwe-valve—i-TWS Valve

1. Cacisa inhloso yei-valveempahleni noma ocingweni

Nquma izimo zokusebenza ze-valve: uhlobo lwendawo esebenzayo, ingcindezi yokusebenza, izinga lokushisa lokusebenza kanye nendlela yokulawula.

2. Khetha kahle uhlobo lwevalvu

Ukukhetha okulungile kohlobo lwe-valve kuyimfuneko ukuze umklami abambe ngokugcwele yonke inqubo yokukhiqiza nezimo zokusebenza.Lapho ekhetha uhlobo lwevalvu, umklami kufanele aqale abambe izici zesakhiwo nokusebenza kwevalvu ngayinye.

3. Thola ukuxhumana kokugcina kwe-valve

Phakathi koxhumano oluluchungechunge, ukuxhumana kwe-flange, nokuxhumana kokugcina okushiselwe, okubili kokuqala yizona ezisetshenziswa kakhulu.Ama-valve anemicu ama-valve ikakhulukazi anobubanzi obuncane obungaphansi kuka-50mm.Uma ububanzi bukhulu kakhulu, ukufakwa nokubekwa uphawu kwengxenye yokuxhuma kuyoba nzima kakhulu.Ama-valve ane-flanged afaneleka kakhulu ukufaka nokuhlakazwa, kodwa asindayo futhi abiza kakhulu kunama-valve anentambo, ngakho afaneleka ukuxhunywa kwamapayipi amadayamitha ahlukahlukene nezingcindezi.Izixhumanisi ezishiselwe zifanele imithwalo esindayo futhi zithembeke kakhulu kunoxhumo lwe-flanged.Kodwa-ke, kunzima ukuqaqa nokufaka kabusha i-valve exhunywe ngokushisela, ngakho-ke ukusetshenziswa kwayo kukhawulelwe ezikhathini lapho ngokuvamile ingasebenza khona ngokwethembeka isikhathi eside, noma lapho izimo zokusetshenziswa zinzima futhi izinga lokushisa liphezulu.

4. Ukukhethwa kwempahla ye-valve

Lapho ukhetha izinto zegobolondo le-valve, izingxenye zangaphakathi nendawo yokubeka uphawu, ngaphezu kokucabangela izakhiwo ezibonakalayo (izinga lokushisa, ingcindezi) kanye nezakhiwo zamakhemikhali (ukugqwala) kwendawo yokusebenza, ukuhlanzeka kwendawo ephakathi (enezinhlayiya eziqinile noma ezingenazo) kufanele futhi ibanjwe.Ngaphezu kwalokho, kuyadingeka ukuthi kubhekiselwe emithethweni efanele yombuso kanye nomnyango wabasebenzisi.Ukukhetha okulungile nokunengqondo kwezinto ze-valve kungathola impilo yesevisi eyonga kakhulu kanye nokusebenza okungcono kakhulu kwe-valve.Ukulandelana kokukhetha okubalulekile komzimba we-valve yilokhu: insimbi engagqwali ye-iron-carbon steel-stainless, kanye nokulandelana kokukhetha okubalulekile kwendandatho yokuvala ithi: irabha-yethusi-alloy steel-F4.

5. Okunye

Ukwengeza, izinga lokugeleza kanye nezinga lokucindezela koketshezi olugeleza nge-valve kufanele futhi kunqunywe, futhi i-valve efanele kufanele ikhethwe kusetshenziswa idatha ekhona (njengeamakhathalogi umkhiqizo valve, amasampula omkhiqizo we-valve, njll.).
