I-WZ Series Metal ihlezi valvu yesango ye-OS&Y
Incazelo:
I-WZ Series Metal ehlezi valvu yesango ye-OS&Y isebenzisa isango lensimbi eliyi-ductile elihlala izindandatho zethusi ukuze kuqinisekiswe uphawu olungangeni manzi. Ivalvu yesango ye-OS&Y (Outside Screw and Yoke) isetshenziswa kakhulu ezinhlelweni zokufafaza zokuvikela umlilo. Umehluko omkhulu kuvalvu yesango ye-NRS (Non Rising Stem) ejwayelekile ukuthi isiqu ne-stem nut zibekwe ngaphandle komzimba wevalvu. Lokhu kwenza kube lula ukubona ukuthi i-valve ivuliwe noma ivaliwe, njengoba cishe ubude bonke besiqu bubonakala lapho i-valve ivuliwe, kuyilapho i-stem ingasabonakali lapho i-valve ivaliwe. Ngokuvamile lokhu kuyimfuneko kulezi zinhlobo zamasistimu ukuze kuqinisekiswe ukulawulwa okubonakalayo okusheshayo kwesimo sesistimu
Uhlu lwezinto:
| Izingxenye | Okubalulekile |
| Umzimba | I-cast iron, i-Ductile iron |

| I-Stem nut | Ithusi/Ithusi |
Isici:
I-Wedge nut:I-wedge nut yenziwe nge-alloy yethusi enekhono lokugcoba elinikeza ukuhambisana okuhle nesiqu sensimbi engagqwali.
I-Wedge:I-wedge yenziwe nge-ductile iron ene-copper alloy face rings enziwe ngendlela efanele ukuze kuqinisekiswe ukuthintana kahle ngamasongo esihlalo somzimba. Amasongo obuso be-wedge akhiwe kahle futhi avikelwe ngokuqinile emkhawulweni. i-wedge iqinisekisa ukuvala okufanayo kungakhathaliseki ukuthi kunezingcindezi eziphakeme.I-wedge inendlu enkulu ye- throught bore yesiqu eqinisekisa ukuthi akukho manzi amile noma ukungcola okungaqoqana.I-wedge ivikelwe ngokugcwele ngokumbozwa kwe-fusion epoxy eboshiwe.
Ukuhlolwa kwengcindezi:
| Ingcindezi yamagama | I-PN10 | I-PN16 | |
| Ingcindezi yokuhlola | Igobolondo | 1.5 Mpa | 2.4 Mpa |
| Ukubeka uphawu | 1.1 Mpa | 1.76 Mpa | |
