Valavu ya mpira yoteteza kuphulika kwa pneumatic

The mpweya  osaphulika Valavu ya mpira imagwiritsa ntchito kapangidwe koyika pamwamba, komwe kumachepetsa mabawuti olumikizira thupi la valavu pansi pa kupanikizika kwakukulu ndi miyeso yayikulu, kumawonjezera kudalirika kwa valavu, ndipo kumatha kuthana ndi mphamvu ya kudzikweza kwa dongosolo pakugwira ntchito kwabwinobwino kwa valavu.

1. Chidule cha Zamalonda za Pneumatic osaphulika Valavu ya Mpira
Valavu ya mpira yolimba yomwe singathe kuphulika imakhala ndi mndandanda wa AT(GT) choyendetsa mpweyandi valavu yoyandama ya mpira, yoyenera kugwiritsidwa ntchito polamulira ndi kuzimitsa. Ili ndi magwiridwe antchito abwino kwambiri otsekera, mphamvu yoyenda bwino, kapangidwe kosavuta, moyo wautali wautumiki, komanso kukonza kosavuta. Choyatsira chomwe chili pafupi nacho chili ndi kapangidwe kosavuta komanso kakang'ono kokhala ndi mphamvu yayikulu yotulutsa. Ikakhala ndi ma switch oyenda osaphulika, ma solenoid valves osaphulika, zochepetsera kuthamanga, ndi mpweya wa 0.4-0.7 MPa, valavu ya mpira yopumira yomwe siphulika imalola ntchito zosinthira ndipo imapereka ma peya awiri a zizindikiro zolumikizana kuti ziwonetse momwe valavu ilili. Choyatsira chimapezeka m'mitundu yogwira ntchito kamodzi ndi kawiri. Ubwino wa choyatsira chimodzi ndikuti ngati magetsi alephera, choyatsira sichiphulika. Vavu ya Mpira wa Pneumatic imagwira ntchito yokha ndi zofunikira za makina owongolera kuti itsegule kapena kutseka malo omwe mukufuna. Valavu ya mpira yolimba yomwe siiphulika imagwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, mafuta, nsalu zopepuka, magetsi, chakudya ndi mankhwala, firiji, ndege, ndi kupanga mapepala. Siingowongolera mpweya, madzi, ndi nthunzi zokha komanso ndi yoyenera kugwiritsa ntchito zinyalala ndi zinthu zokhala ndi ulusi.
2, Mbali za malonda a valavu ya mpira yoteteza kuphulika kwa pneumatic
(1) Valvu ya mpira ndi imodzi mwa mitundu ya ma valve omwe ali ndi kukana kochepa kwa madzi, ngakhale ma valve a mpira omwe ali ndi mainchesi ochepa, kukana kwake kwa madzi ndi kochepa kwambiri.
(2) Maberiyani othyola amachepetsa mphamvu ya kukangana kwa tsinde la valavu, zomwe zimathandiza kuti tsinde la valavu ligwire ntchito bwino komanso mosinthasintha kwa nthawi yayitali.
(3) Mpando wa valavu uli ndi magwiridwe antchito abwino otsekera ndipo umapangidwa ndi mphete zotsekera zopangidwa ndi zinthu monga polytetrafluoroethylene. Kapangidwe kake n'kosavuta kutseka, ndipo mphamvu yotsekera ya valavu ya mpira imawonjezeka ndi kuwonjezeka kwa mphamvu yapakati.
(4) Chisindikizo cha tsinde la valavu ndi chodalirika. Popeza tsinde la valavu limazungulira lokha ndipo silikukwera mmwamba kapena pansi, chisindikizo chowonjezera cha tsinde la valavu sichimawonongeka mosavuta, ndipo mphamvu yotsekera imawonjezeka ndi kuwonjezeka kwa mphamvu yapakati.
