Iivalvu zeglobhu zentsimbi eyenziweyozahlulwe zibeiivalvu zeglobhu zentsimbi yekhabhoni ezenziweyokwayeiivalvu zeglobhu zentsimbi engagqwaliyo ezenziweyo, esetyenziswa rhoqo kwiimeko zoxinzelelo oluphezulu noluphakathi (150lb-800lb, 1500LB, 2500LB), kunye neemeko zobushushu obuphezulu nobuphantsi (-196℃ ~ 700℃), iivalvu zentsimbi ezibunjiweyo zinamandla aphezulu kunye neempawu ezingcono zoomatshini ukuhlangabezana neemfuno zoxinzelelo oluphezulu. Kodwa kuphela kwinkqubo yokubumba, idla ngokusebenza kuphela kubungakanani obuncinci nobuphakathi (1/2 “, 3/4 “, 1 “, 1-1/4 “, 1-1/2 “, 2, 2-1/2 “, 3 “kunye ne-4”.
Umsebenzi weValve ungaba ngowokusebenzisa i-manual, i-bevel gear, i-pneumatic actuator, i-electric actuator, i-hydraulic actuator, i-pneumatic-hydraulic, i-electro-hydraulic.
Iingenelo zesakhiwo sevalvu yeglobhu yentsimbi eyenziweyo
1. Ivalvu yeglobhu yentsimbi eyenziweyo isebenzisa isitywina esiziqinisayo soxinzelelo, kwaye zombini iziphelo zombhobho wegatsha lomzimba wevalvu ziyadityaniswa.
2. Isihlalo sevalvu yeglobhu yentsimbi eyenziweyo, umphezulu wokutywina idiski yevalvu wenziwe nge-cobalt-based cemented carbide plasma spray welding, ukumelana nokuguguleka, ukumelana nokukrweleka okuphezulu.
3. Isiqu sevalvu siphathwa nge-nitriding yokumelana nokugqwala, enokumelana nokugqwala okuhle kunye nokumelana nokugqwala.
4 kwinkqubo yokuvula nokuvala, ngenxa yokuba idiski yevalvu emzimbeni wevalvu yokutywina, ukungqubana komphezulu womphezulu kuncinci, kwaye ukumelana nokuguguleka kuncinci.
5. Ngokwesiqhelo kukho ubuso bokuvala obunye kuphela emzimbeni wevalvu kunye nediski, ngoko ke inkqubo yokuvelisa ingcono kwaye ilungele ukugcinwa
Ivalvu kufuneka ihlolwe ngaphambi kokuba ifakwe, kwaye umgangatho woyilo lwevalvu kufuneka uhambelane ne-API 602 yangoku yamazwe ngamazwe. Uvavanyo lokuqina nokusebenza kokuqina kufuneka lwenziwe ngaphambi kokuba ifakwe.
Kuvavanyo lwamandla, uxinzelelo lovavanyo luphindwe kayi-1.5 koxinzelelo oluqhelekileyo, kwaye ubude balo abuyi ngaphantsi kwemizuzu emi-5.
Igobolondo yevalvu kunye nokutywinwa kwesihlalo sangasemva kufuneka kuqinisekiswe ukuba akukho kuvuza.
Uvavanyo lokutywina, uxinzelelo lovavanyo luphindwe ka-1.1 koxinzelelo oluqhelekileyo;
Uxinzelelo lovavanyo ngexesha lovavanyo kufuneka luhlangabezane neemfuno zomgangatho we-API 598, kungabikho kuvuza kumphezulu wokutywina idiski njengoko kufanelekile.
