I-FDO4-BV1-3L (Ukusebenza okuphezulu kwebhabhathane)
Ngokufutshane
Inempawu ezintle zokufudumeza kunye nokubanda, kwaye ubukhulu bevalve buhambelana nobubanzi bepayipi, kwaye bunokunciphisa ngempumelelo ukulahleka kobushushu kwaphakathi kumbhobho. Ukuhambisa indawo ephezulu ye-viscosity eya kuthi yomelele kubushushu begumbi. Ngokwendlela eyahlukileyo yevalve, isetyenziswa ngokubanzi kwinkqubo yombhobho wolwakhiwo lwasezidolophini, ishishini lamachiza, isinyithi, ipetroleum, amayeza, ukutya, isiselo, ukhuselo lokusingqongileyo kunye namanye amashishini.
Imigangatho
1. Uhlobo olusebenzayo oluhlengahlengisiweyo lokusika. Ingasetyenziswa njengevalivali yokuvala kunye neyokuvala ivalve.
2. Iindlela ezimbini zokutywina, ezahlukileyo ekutywinweni kwendlela enye, zinokutywinwa ngokuthembekileyo kwanaxa ukubuyela umva okuphakathi okanye into eyenzekayo "yinyundo yomoya".
3. Umzimba wevalufa wamkela itekhnoloji yokuphosa ngokuhambelana nesakhiwo esihambelanayo, umthamo omncinci kunye nobunzima bokukhanya;
4. Ulwakhiwo olumbaxa-mbini lwamkelwe. Xa kuvalwa, ipleyiti yevalufa yanda ngaphandle ukufezekisa imeko yokutywina esemgangathweni; xa kuvulwa, ipleyiti yevalve kunye netywina lokutywina zahlulwe ngokukhawuleza ukuthintela ngokufanelekileyo ukunxiba kwendandatho yokutywina. Ngale ndlela, i-torque yokusebenza iyancitshiswa kwaye ubomi obusebenzayo bevalve buyanda.
5. Isangqa setywina yinoveli kuyilo kwaye samkela itekhnoloji ephezulu kwihlabathi: Isitywina se-PTFE samkela "imilebe yomlomo" imilo yokutywina; uphawu olomeleleyo lusebenzisa u "U" ukumila kwetywina. Ubomi benkonzo yolwakhiwo lokutywina lude kwaye luthembekile. Ngokumalunga neemeko zetywina elithambileyo kunye netywina elinzima, ixhomekeka ikakhulu kwiimfuno zomsebenzisi, iimeko zenkonzo kunye neemfuno zokulwa umhlwa.
