Imininingwane yesimiso sokusebenza se-valve yase-China: nqamula noma xhuma umzila owuketshezi

Imininingwane yesimiso sokusebenza se-valve yase-China: ukusika noma ukuxhuma uketshezi lwe-valve yaseShayina iyithuluzi lokulawula uketshezi elivame ukusetshenziswa, umgomo walo osebenzayo uwukubona ukulawula uketshezi ngokuvala noma ukuxhuma uketshezi oluwuketshezi. Lesi sihloko sizokunikeza isingeniso esiningiliziwe somgomo wokusebenza we-valve yaseChina ngokombono wochwepheshe. 1. Indlela esebenza ngayo Umsebenzi oyinhloko wevalvu yokumisa ukusika noma ukuxhuma uketshezi olusemgqeni wepayipi ukulawula izinga lokugeleza nokucindezela koketshezi. Lapho i-valve yokumisa yaseShayina ivaliwe, uketshezi alukwazi ukudlula ku-valve; Lapho i-valve yokumisa yaseShayina ivuliwe, uketshezi lungadlula kuvalvu. Isimiso sokusebenza se-valve yeglobu yaseShayina sisekelwe esakhiweni se-piston noma ikheshi. Lapho okuphakathi (okufana negesi noma uketshezi) kudlula ku-valve yokumisa yaseShayina, ukucindezela kwendawo ephakathi kuyokwenza i-piston noma ikheshi liye phansi, elizocindezela indawo yokuvala ye-valve kuzo zombili iziphetho zesiteshi futhi kuvimbele ukuvala ukugeleza kwe-medium. Uma kudingekile ukuvula i-valve, vele uphakamise ipiston noma ikheshi phezulu ukuze wenze indawo yokuvala ishiye iziphetho ezimbili zesiteshi ukuze wenze ukugeleza okuphakathi. 2. Ukuhlukaniswa nezici Ngokwesakhiwo esihlukene nokusetshenziswa, ama-valve eglobhu aseShayina angahlukaniswa abe uhlobo oluqondile, uhlobo lwe-Angle, uhlobo lwezindlela ezintathu nezinye izinhlobo. Izinhlobo ezahlukene zama-valve embulunga yaseShayina zinezici ezihlukene kanye nobubanzi bokusebenza. (1) Ivalvu yeglowubhu yaseShayina eqondile: Ivalvu yeglowubhu yaseShayina eqondile iwuhlobo oluvame ukusetshenziswa kakhulu lwevalvu yaseShayina, enesakhiwo esilula, ukwakhiwa okulula kanye nenani eliphansi. Ivalvu yeglobu yaseShayina eqondile ifanele umfutho ophansi, izinhlelo zokusebenza ezinkulu zokulawula uketshezi olugelezayo. (2) I-valve yeglowubhu ye-Angle Chinese: I-valve yeglowubhu ye-angle yamaShayina iwuhlobo lwevalvu yembulunga yaseShayina evamile, ukwakheka kwayo kuyinkimbinkimbi kakhulu, kodwa inokusebenza okungcono kokuvala nokusebenza kokulungiswa. I-Angle Chinese globe valve ilungele ukucindezela okuphezulu, izinhlelo zokusebenza zokulawula uketshezi olugelezayo oluncane. (3) Ivalvu yeglowubhu yesiShayina enendlela-ntathu: Ivalvu yeglowubhu yaseShayina enendlela ezintathu iwuhlobo lwevalvu yeglobhu yaseShayina esebenza ngezindlela eziningi engasetshenziswa ukulawula izinhlangothi ezintathu zesiteshi soketshezi. Ivalvu yeglobu yesiShayina enezinhlangothi ezintathu ilungele ukusetshenziswa lapho imigudu yoketshezi engaphezu kwemibili idinga ukulawulwa kanyekanye. Ngamafuphi, izinhlobo ezahlukene zamavalvu eglobhu aseShayina zinezici ezihlukene kanye nobubanzi bokusebenza, futhi uhlobo olufanele lwamavalvu eglobhu aseShayina kufanele lukhethwe ngokuya ngezimo ezithile zokusebenza kanye nezidingo zokusebenzisa. Ngethemba ukuthi ukwethulwa kwalesi sihloko kungakunikeza ireferensi nosizo.
