Valavu yanzeru yamagetsi ndi pneumatic Positioner

Choyimira ma valve, chomwe ndi chowonjezera chachikulu cha valavu yowongolera, choyimira ma valve ndiye chowonjezera chachikulu cha valavu yowongolera, chomwe chimagwiritsidwa ntchito kuwongolera kuchuluka kwa kutsegula kwa valavu yoyendetsa mpweya kapena yamagetsi kuti zitsimikizire kuti valavuyo ikhoza kuyima molondola ikafika pamalo omwe adakonzedweratu. Kudzera mu ulamuliro wolondola wa choyimira ma valve, kusintha kolondola kwa madzi kumatha kuchitika kuti kukwaniritse zosowa za njira zosiyanasiyana zamafakitale. Zoyimira ma valve zimagawidwa m'magulu oyimira ma valve oyendera mpweya, oyimira ma valve oyendera magetsi ndi oyimira ma valve anzeru malinga ndi kapangidwe kawo. Amalandira chizindikiro chotulutsa cha wowongolera kenako amagwiritsa ntchito chizindikiro chotulutsa kuti alamulire valavu yowongolera mpweya. Kusamuka kwa tsinde la valavu kumabwezeretsedwa ku choyimira ma valve kudzera mu chipangizo chamakina, ndipo mkhalidwe wa valavu umatumizidwa ku dongosolo lapamwamba kudzera mu chizindikiro chamagetsi.

Ma valve positioners a pneumatic ndi mtundu wosavuta kwambiri, wolandira ndi kubwezera zizindikiro kudzera mu zipangizo zamakina.

Choyimira valavu yamagetsi ndi pneumatic chimaphatikiza ukadaulo wamagetsi ndi pneumatic kuti chiwongolere kulondola ndi kusinthasintha kwa ulamuliro.
Choyimira ma valve chanzeru chimayambitsa ukadaulo wa microprocessor kuti chikwaniritse zochita zokha zapamwamba komanso kuwongolera mwanzeru.
Ma valve positioner amagwira ntchito yofunika kwambiri mu makina odziyimira pawokha a mafakitale, makamaka pazochitika zomwe kuwongolera bwino kayendedwe ka madzi kumafunika, monga mafakitale a mankhwala, mafuta, ndi gasi. Amalandira zizindikiro kuchokera ku makina owongolera ndikusintha molondola kutseguka kwa valavu, motero amawongolera kuyenda kwa madzi ndikukwaniritsa zosowa za njira zosiyanasiyana zamafakitale.
