Pneumaticvalavu ya gulugufendi mtundu wa valavu yowongolera yomwe imagwiritsidwa ntchito kwambiri m'mapaipi amafakitale. Chigawo chake chachikulu ndi diski yooneka ngati diski yomwe imayikidwa mu chitoliro ndikuzungulira pa mzere wake. Disk ikazungulira madigiri 90, valavu imatseka; valavu ikazungulira madigiri 0, imatseguka.

Mfundo yogwirira ntchito ya valavu ya gulugufe yachitsulo chosapanga dzimbiri ya pneumatic ndikuwongolera kuzungulira kwa mbale ya gulugufe kudzera mu actuator ya pneumatic. Actuator ya pneumatic imalandira mpweya wopanikizika ngati gwero lamagetsi, ndipo imayendetsa mbale ya gulugufe kuti itsegule kapena kutseka malinga ndi zofunikira za chizindikiro chowongolera. Njira yoyendetsera iyi imapangitsa valavu ya gulugufe ya pneumatic kukhala ndi ubwino wa liwiro loyankha mwachangu, kulondola kwambiri, kugwira ntchito kosavuta ndi zina zotero.

Ma valve a gulugufe a pneumatic amagwiritsidwa ntchito kwambiri m'mafakitale. Amagwiritsidwa ntchito makamaka kusintha kuchuluka kwa madzi ndi kuthamanga kwa sing'anga, komanso kukwaniritsa kudula ndi kulumikiza payipi. Chifukwa cha kapangidwe kake kosavuta, kukula kwake kochepa komanso kulemera kwake kopepuka, valavu ya gulugufe ya pneumatic eccentric imakhala ndi kayendedwe kabwino ka madzi mu dongosolo la mapaipi, zomwe zimachepetsa kukana kwa madzi ndi kugwiritsa ntchito mphamvu. Kuphatikiza apo, valavu ya gulugufe ya pneumatic ya mainchesi 4 imakhalanso ndi kukana dzimbiri komanso kukana kutentha kwambiri, ndipo imatha kusintha kuti igwirizane ndi malo osiyanasiyana ovuta.

Ma valve a gulugufe a pneumatic amagwiritsidwa ntchito m'mafakitale ambiri, monga petrochemical, magetsi, zitsulo, mankhwala, chakudya ndi zina zotero. Mu makampani opanga petrochemical, ma valve a gulugufe a pneumatic nthawi zambiri amagwiritsidwa ntchito mu mapaipi a mafuta osakonzedwa, mafuta oyengedwa, zinthu zopangira mankhwala ndi zina. Mu makampani opanga magetsi, ma valve a gulugufe a pneumatic amagwiritsidwa ntchito makamaka mu mapaipi otumizira madzi ozizira, gasi wamafuta ndi zina m'mafakitale opanga magetsi. Mu makampani opanga zitsulo, ma valve a gulugufe a pneumatic amagwiritsidwa ntchito mu mapaipi okhala ndi zitsulo zosungunuka kutentha kwambiri ndi zina.

Mwachidule, valavu ya gulugufe yothamanga mpweya imagwira ntchito yofunika kwambiri mu dongosolo la mapaipi a mafakitale ndi kapangidwe kake kapadera komanso mfundo yogwirira ntchito. Sikuti imangotha ​​kuwongolera molondola kayendedwe ka madzi ndi kuthamanga kwa mpweya, komanso imalimbana bwino ndi dzimbiri komanso kutentha kwambiri, kotero imagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana amafakitale.
