Ivalvu yeplagi ye-API 6A ephezulu okanye esezantsi ivalvu yeplagi yokungena

Inkcazo emfutshane:

Xa kuthelekiswa nevalvu yeplagi ekumgangatho ophezulu, iivalvu zeplagi ziivalvu ezine "iiplagi" ezisilinda okanye ezicolekileyo ezinokujikeleziswa ngaphakathi komzimba wevalvu ukulawula ukuhamba kwevalvu. Iiplagi kwiivalvu zeplagi zinendlela enye okanye ezingaphezulu ezingenanto eziya ecaleni kweplagi, ukuze ulwelo lukwazi ukuhamba ngeplagi xa ivalvu ivuliwe.

✧ Inkcazo

Ivalvu yeplagi yinxalenye ebalulekileyo esetyenziswa kwi-manifold enoxinzelelo oluphezulu kwimisebenzi yokusimisa nokuqhekeza kwindawo yeoyile kwaye ikwalungele ukulawula ulwelo olufana nolo loxinzelelo oluphezulu. Inesakhiwo esincinci, kulula ukuyilungisa, i-torque encinci, ukuvulwa ngokukhawuleza kunye nokusebenza okulula, ivalvu yeplagi ifanelekile kwii-manifold zokusimisa nokuqhekeza.

Ngokuphathelele ukusebenza, ivalvu yeplagi ingaqhutywa ngesandla, nge-hydraulic, okanye ngombane, nto leyo enika ukuguquguquka kokuhlangabezana neemfuno ezithile zolawulo kunye ne-automation. Ngokusebenza ngesandla, ivalvu ixhotyiswe nge-handwheel okanye i-lever evumela ukulungiswa okulula nokuchanekileyo kwendawo yeplagi. Ngokusebenza ngokuzenzekelayo, ivalvu ingaxhotyiswa ngee-actuators eziphendula kwiimpawu ezivela kwinkqubo yolawulo, ezivumela ukusebenza okukude kunye nolawulo oluchanekileyo lokuhamba kwamanzi.

✧ Imigaqo Yokusebenza Neempawu

Ivalvu yeplagi inomzimba wevalvu, isiciko seplagi, iplagi njalo njalo.

Ivalvu yeplagi iyafumaneka kunye namalungiselelo okungena kunye nokuphuma kwe-union 1502 (ikwafumaneka xa umthengi ecela). Udonga lwangaphakathi lomzimba wesilinda kunye namacandelo asecaleni asebenza kunye namacandelo esitywino serabha ukubonelela ngokutywinwa.

Ukutywinwa kwesinyithi kwisinyithi kufumaneka phakathi kwamacandelo asecaleni kunye neplagi yesilinda, enokuchaneka okuphezulu kunye nokuthembeka.

Qaphela: ivalvu inokuvulwa okanye ivalwe lula nokuba iphantsi koxinzelelo oluphezulu lwe-10000psi.
