Leyon yavutha i-NRS Gate Ductile Iron Resilient Seate Resilient Sang Valve

Izingxenye ezisemqoka

1. Izinto zomzimba: insimbi evuthayo
   • Ukufanisa: Isidumbu se-valve senziwe nge-rouctile iron, impahla enikeza amandla aphezulu, ukumelana nomthelela, kanye nokuvumelana nezimo ngokuqhathaniswa nensimbi yendabuko yendabuko.
   • Izinzuzo:
     • Ukumelana okuphakeme ekucindezelekeni okwenziwe ngomshini nokushaqeka.
     • Ingcindezi ephezulu kanye nokumelana nokushisa kwensimbi empunga.
     • Ukumelana okungcono kokugqwala lapho kuhlanganiswe (isib. Ngenhlanganisela ye-epoxy) ukuze isetshenziswe ezinhlelweni zamanzi.
2. Isango (disc)
   • Ukufanisa: Isango, elivame ukwenziwa nge-iron ye-ructile, libuye lifakwe ngokuphelele ezintweni eziphefumula ngokuphelele (injoloba evamile ye-EPDM) ukuhlinzeka nge-bubble-tight-tight-tight tight.
   • Izinzuzo:
     • Izinto ezisebenzayo zivumela aI-Teath, Ubufakazi Book Proof.
     • Yehlisa ukugqoka futhi ukuklebhula ezindaweni zokubopha, ukuqina okukhulayo kanye nesikhathi sokuphila.
3. Isiqu esingakhuphuki (NRS)
   • Ukufanisa: Ngokungafani nama-valves akhuphukayo, isiqu sihlala simile njengoba isango liphuma phezulu naphansi.
   • Izinzuzo:
     • Idizayini yokusindisa isikhala: Ilungele ukufakwa ezikhaleni ezivalekile noma amasistimu angaphansi komhlaba lapho indawo ebheke phezulu ilinganiselwe.
     • Izicucu ezivikelwe: Njengoba imicu ingaphakathi komzimba we-valve, ayizange inciswe ukungcola, ukugqwala kanye nomonakalo owenziwe ngomshini.
4. Isihlalo sokukhuthazela
   • Ukufanisa: Isihlalo sokukhuthazela ngokwejwayelekile senziwa ngerabha (isib. I-EPDM), esibunjiwe esiya esangweni.
   • Izinzuzo:
     • Inikeza ashutha eliqinilengaphandle kokuxhumana ngensimbi.
     • Yehlisa ukuvuza futhi unikeze isikhathi eside sokuphila ngenxa yokumelana kwayo ngesando samanzi kanye nokucindezela kwengcindezi kamanzi.
5. Uhlelo lwe-bonnet kanye novalo
   • Ukufanisa: I-bonnet ivalwe ngokujwayelekile emzimbeni we-valve, ngohlelo lokubopha uphawu kusetshenziswa ama-o-rings noma ama-gaskets ukuvimbela ukuvuza.
   • Izinzuzo:
     • Kulula ukuqaqa ngokulungiswa nokulungiswa.
     • Ukubekwa uphawu okusebenzayo ukuvikela ukuvuza emzimbeni we-valve.
6. Ukuvikelwa Nokuvulwa Kokugqwala
   • Ukufanisa: Ama-rouctile iron valves ajwayele ukuhlanganiswaI-Fusion-Bonded Epoxy (FBE)noma ukumbona okufanayo ukuvikela ekugqwaneni, ikakhulukazi ezinhlelweni zamanzi ezisebenzisekayo.
   • Izinzuzo:
     • Ihlinzeka ngokumelana nokugqwayiza okuphezulu.
     • Iqinisekisa ukuhambisana namazinga okuphuza okuphuza amanzi (isib. Isitifiketi se-NSF / ANSI 61).
