I-WZ Series Metal ehleli kwi-OS&Y gate valve
Inkcazo:
Ivalvu yesango le-OS&Y ehleli kwi-WZ Series Metal isebenzisa isango lesinyithi elithambileyo eligcina iindandatho zobhedu ukuqinisekisa ukuba ayinamanzi. Ivalvu yesango le-OS&Y (Outside Screw and Yoke) isetyenziswa kakhulu kwiinkqubo zokutshiza umlilo. Umahluko ophambili kwivalvu yesango ye-NRS (Non Rising Stem) eqhelekileyo kukuba isiqu kunye ne-nut yesiqu zibekwe ngaphandle komzimba wevalvu. Oku kwenza kube lula ukubona ukuba ivalvu ivuliwe okanye ivaliwe, njengoko phantse ubude bonke besiqu bubonakala xa ivalvu ivuliwe, ngelixa isiqu singasabonakali xa ivalvu ivaliwe. Ngokubanzi oku kuyimfuneko kwezi ntlobo zeenkqubo ukuqinisekisa ulawulo olubonakalayo olukhawulezayo lwemeko yenkqubo.
Uluhlu lwezinto ezisetyenzisiweyo:
| Iinxalenye | Izinto eziphathekayo |
| Umzimba | Isinyithi esiphosiweyo, isinyithi esithambileyo |
| Idiski | Isinyithi esiphosiweyo, isinyithi esithambileyo |
| Isiqu | I-SS416, i-SS420, i-SS431 |
| Indandatho yesihlalo | Ubhedu/ubhedu |
| Ibhonethi | Isinyithi esiphosiweyo, isinyithi esithambileyo |
| I-Stem nut | Ubhedu/ubhedu |
Uphawu:
I-Wedge nut: I-wedge nut yenziwe nge-alloy yobhedu enezakhono zokuthambisa ezibonelela ngokuhambelana ngokugqibeleleyo nesiqu sentsimbi engagqwali.
I-Wedge: I-wedge yenziwe ngentsimbi ethambileyo ene-copper alloy face rings ezifakwe kwi-machined ukuya kumphezulu ococekileyo ukuqinisekisa ukuba i-contact seal ifanelekile ngee-seat body seat rings. Ii-wedge face rings zifakwe ngomatshini ngokuchanekileyo kwaye ziqiniswe kwi-wedge. Izikhokelo ezikwi-wedge ziqinisekisa ukuvalwa okufanayo nokuba uxinzelelo luphezulu. I-wedge ine-throught bore housing enkulu yesiqu eqinisekisa ukuba akukho manzi angashukumiyo okanye izinto ezingafunekiyo ezinokuqokelelana. I-wedge ikhuselwe ngokupheleleyo yi-coating ye-fusion bonded epoxy.
Uvavanyo loxinzelelo:
| Uxinzelelo oluqhelekileyo | I-PN10 | I-PN16 | |
| Uxinzelelo lovavanyo | Iqokobhe | 1.5 Mpa | 2.4 Mpa |
| Ukutywina | 1.1 Mpa | 1.76 Mpa | |
