Ungakhetha kanjani i-valve yesheke yensimbi engenasici?

I-valve yokuhlola i-wafer yensimbi engagqwali iyivalvu ezenzakalelayo enamamodeli amaningi kanye nokucaciswa kwayo.Lolu hlobo lomkhiqizo lusetshenziselwa ikakhulukazi ukuvimbela ukugeleza emuva kwe-medium, ukuzungeza okuhlanekezela kwepompo kanye nemoto yayo yokushayela, kanye nokukhishwa kwe-medium esitsheni.Ingasetshenziswa ezinhlobonhlobo kulayini ophakathi.Ngakho-ke sikhetha kanjani i-valve yokuhlola i-wafer yensimbi engenasici?Yini okufanele inakwe?

1. Ngokuvamile kunconywa ukuthi abasebenzisi bakhethe amavalvu okuhlola amawafa ensimbi avaliwe ngokuqinile ukuze kuqinisekiswe ukuthi amavalvu okuhlola amawafa anokuphila kwesevisi okude, izinga lokushisa eliphezulu lokusebenza, nokusebenza okuhle okufanayo kokuvala.

2. Uma ubukhulu begama bukhulu noma bulingana ne-DN100 (NPS4), kuhle ukhetheI-H76 yohlobo lwe-valve yokuhlola i-wafer ye-disc ephindwe kabili, okunganciphisa ngokuphumelelayo ukulahlekelwa ukumelana noketshezi lwe-valve yokuhlola;usayizi okuzisholo ungaphansi noma ulingana ne-DN80 (NPS3), futhi ukukhethwa kwe-valve yokuhlola yokuphakamisa uhlobo lwe-H71 kufanelekile.

3. II-valve yokuhlola i-wafer yohlobo lwe-H71enobukhulu obujwayelekile obungaphansi noma obulingana ne-DN100 (NPS) ngokuvamile ayikhiqizwa ngenxa yesakhiwo sayo esihlangene futhi kucatshangelwa inqubo yokucubungula nokukhiqiza.Kunconywa ukuthi abasebenzisi bakhethe ama-valve okuhlola ama-wafer ensimbi engagqwali.i-valve.

4. Ngaphezu kohlobo lwe-wafer, i-valve yokuhlola i-disc yensimbi engenasici futhi inohlobo lwe-lug nohlobo lwe-flange.Uma umsebenzisi engenazo izidingo ezikhethekile, ifomu lesakhiwo ngokuvamile likhiqizwa inkampani yethu ngokuvumelana nezindinganiso ezivamile.Amanye ama-valve okuhlola ama-disc aphindwe kabili angaklanywa ngesakhiwo se-flange esiphindwe kabili (uhlobo H46).

5. I-lug flange ye-lug double flap swing check valve idlala indima yokumisa kuphela, futhi i-lug ayinawo amandla omshudo, ngakho-ke ubukhulu be-lug flange abuklanyelwe ngokuhambisana nobukhulu be-flange evamile, ngokuvamile. i-lug flange Ugqinsi lungaphansi kolwama-flange ajwayelekile.I-flange ye-double flange yokuxhumeka kwe-double disc swing check valve ithwala amandla e-bolt, futhi ubukhulu be-flange buklanywe ngokwezinga le-flange.

6. Ama-valve okuhlola ama-wafer ohlobo lwe-lift anezingcindezi ezithi PN10, PN16, PN25 kanye ne-PN40 anochungechunge olubili lobude besakhiwo.Intengo yama-valve okuhlola uchungechunge olufushane iphansi, kodwa ama-gaskets okuxhuma okungajwayelekile angadingeka phakathi kwe-valve yokuhlola kanye ne-flange yepayipi.Uma kusetshenziswa ama-valve okuhlola ochungechunge olude, ama-flange gaskets ajwayelekile angalungiswa.
