Amaphuzu ayinhloko okukhetha ama-valve—i-TWS Valve

1. Cacisa inhloso yalokhuivalvuemshinini noma kudivayisi

Nquma izimo zokusebenza zevalvu: uhlobo lwendawo esetshenziswayo, ingcindezi yokusebenza, izinga lokushisa lokusebenza kanye nendlela yokulawula.

2. Khetha uhlobo lwevalvu ngendlela efanele

Ukukhetha uhlobo lwevalvu olufanele kuyimfuneko ukuze umklami ayiqonde ngokugcwele yonke inqubo yokukhiqiza kanye nezimo zokusebenza. Lapho ekhetha uhlobo lwevalvu, umklami kufanele aqale aqonde izici zesakhiwo kanye nokusebenza kwevalvu ngayinye.

3. Nquma ukuxhumeka kokuphela kwevalvu

Phakathi kokuxhumeka okunezintambo, ukuxhumeka kwe-flange, kanye nokuxhumeka kokuphela okuhlanganisiwe, okubili kokuqala yikona okusetshenziswa kakhulu. Ama-valve anezintambo ikakhulukazi ama-valve anobubanzi obungaphansi kwama-50mm. Uma ububanzi bukhulu kakhulu, ukufakwa nokuvalwa kwengxenye exhumanisayo kuzoba nzima kakhulu. Ama-valve anezintambo kulula kakhulu ukuwafaka nokuwahlukanisa, kodwa anzima futhi abiza kakhulu kunama-valve anezintambo, ngakho-ke afaneleka ukuxhumeka kwamapayipi anobubanzi obuhlukahlukene kanye nokucindezela. Ukuxhumeka okuhlanganisiwe kufanelekile emithwalweni esindayo futhi kuthembekile kakhulu kunokuxhumeka okuhlanganisiwe. Kodwa-ke, kunzima ukukuhlukanisa nokufaka kabusha i-valve exhunywe ngokuhlanganisa, ngakho-ke ukusetshenziswa kwayo kunqunyelwe ezikhathini lapho ivame ukusebenza khona ngokwethembeka isikhathi eside, noma lapho izimo zokusebenzisa zinzima futhi izinga lokushisa liphezulu.

4. Ukukhethwa kwezinto zevalvu

Uma ukhetha izinto zegobolondo le-valve, izingxenye zangaphakathi kanye nobuso bokuvala, ngaphezu kokucabangela izakhiwo zomzimba (izinga lokushisa, ingcindezi) kanye nezakhiwo zamakhemikhali (ukubola) kwendawo yokusebenza, ukuhlanzeka kwendawo yokusebenza (enezinhlayiya eziqinile noma ezingenazo) kufanele futhi kuqondwe. Ngaphezu kwalokho, kubalulekile ukubhekisela emithethweni efanele yesifundazwe kanye nomnyango wabasebenzisi. Ukukhetha okufanele nokunengqondo kwezinto ze-valve kungathola impilo yesevisi engabizi kakhulu kanye nokusebenza okungcono kakhulu kwe-valve. Uchungechunge lokukhetha izinto zomzimba we-valve luyi: insimbi ephonswe ngensimbi-ikhabhoni-insimbi engagqwali, kanti uchungechunge lokukhetha izinto zendandatho yokuvala luyi: insimbi yerabha-yethusi-i-alloy-F4.

5. Okunye

Ngaphezu kwalokho, izinga lokugeleza kanye nezinga lokucindezela koketshezi olugeleza ngevalvu kufanele futhi kunqunywe, futhi ivalvu efanele kufanele ikhethwe kusetshenziswa idatha ekhona (njengeamakhathalogi omkhiqizo we-valve, amasampula omkhiqizo we-valve, njll.).
