Ukubonisa umlingani
Indlela yokusebenza yevalvu yebhola eyodwa ukulawula indawo yebhola ngokujikeleza i-spool, ngaleyo ndlela kushintsha usayizi wesiteshi soketshezi noma ukufeza ukunqanyulwa kokugeleza. Ngokukhethekile, lapho isiqu sijikeleza, kubangela ukuthi ibhola lijikeleze, okushintsha ukugeleza kuketshezi noma kuphazamise ukugeleza. Endaweni evaliwe, ibhola licindezelwa esihlalweni ngomfutho womshini wesiqu sevalvu; Uma kuvulwa, isiqu siyaphakama futhi sijikeleze ibhola kuze kube yilapho livulwa ngokuphelele. Ivalvu yebhola eyodwa iwuhlobo olusha lwesigaba samavalvu ebholayo, enezinzuzo ezithile ezihlukile zesakhiwo sayo, njengokungabi khona kokungqubuzana ekushintsheni, ukuvalwa akulula ukuguga, futhi i-torque yokuvula nokuvala incane. Lokhu kunciphisa usayizi we-actuator ehlelwe. Nge-actuator kagesi ye-multi-turn, umthombo ungahlanganiswa futhi unqanyulwe ngokuqinile. Isetshenziswa kabanzi ku-petrochemical ukuhlinzekwa kwamanzi edolobheni nokudonswa kwamanzi nezinye izimo ezidinga ukunqanyulwa okuqinile.
