Vavu ya Pneumatic Ball, Vavu Yowongolera Yokha

Makhalidwe Azinthu

valavu ya mpira wa pneumatic ya GB ndi valavu yowongolera yozungulira yokhala ndi ngodya yozungulira ya 90 °. Imakhala ndi cholumikizira chamtundu wa pisitoni ya pneumatic ndi valavu ya mpira wamtundu wa O-valve. Pakatikati pa valve imatenga mpira wa cylindrical kudutsa-bowo, ndipo zosindikizira zimagawidwa m'mitundu iwiri: kusindikiza kofewa ndi kusindikiza kolimba.
valavu ya mpira wa pneumatic ya GB imatenga mpweya woponderezedwa ngati gwero la mphamvu, imavomereza zizindikiro zosintha monga distributed control system (DCS), programmable logic controller (PLC), etc.
valavu ya mpira wa pneumatic ya GB imagwiritsa ntchito thupi la valve yowongoka. Malo ozungulira amakonzedwa ndikuumitsidwa ndi ukadaulo wapadera, kotero kuti pamwamba pake ndi yosalala komanso yosamva kuvala, yokhala ndi moyo wautali wautumiki, mawonekedwe ophatikizika, zochita zodalirika, mphamvu yothamanga kwambiri, koyefithi yaing'ono yolimbana ndi kutuluka, kukhazikitsa kosavuta komanso ntchito yabwino. Zinthu monga ntchito yodulidwa ndikugonjetsa kusiyana kwakukulu kwa kuthamanga. Zogulitsa zimagwiritsidwa ntchito kwambiri popanga mapepala, petrochemical, zitsulo, zakuthambo, chakudya, mankhwala, chithandizo chamadzi ndi mafakitale ena, makamaka poyang'anira ndondomeko ya kukhuthala kwakukulu ndi zofalitsa zomwe zimakhala ndi fiber.
Pneumatic pisitoni actuators akhoza kugawidwa mu single-kuchita ndi awiri akuchita. Pamene makina opangira ma pneumatic awiri amachotsedwa panthawi yomwe amagwiritsidwa ntchito, valavu imakhalabe pamalo otsekedwa kuti ipitirize kupanga. Valavu yokhala ndi imodzi yokha ili pamalo oyambira malire (otseguka kwathunthu kapena otsekedwa kwathunthu) pamene mphamvu kapena mpweya watayika kuti zitsimikizire kuti njira yopangira ili pamalo otetezeka.
