Valavu yapamwamba kwambiri ya pulagi yopaka mafuta m'mafakitale achilengedwe ku China wopanga fakitale
Kodi valavu yolumikizira mafuta ya gasi wachilengedwe ndi chiyani?
Valavu yolumikizira mpweya wachilengedwe Ili ndi dzenje pakati pa pulagi motsatira mzere wake. Dzenje ili limatsekedwa pansi ndipo limayikidwa cholumikizira cholumikizira pamwamba. Cholumikizira chimalowetsedwa m'dzenjemo, ndipo valavu yowunikira pansi pa cholumikizira cholumikizira imaletsa cholumikizira kuti chisayende mozungulira.
Pofuna kuchepetsa mphamvu ya ma valve a pulagi opangidwa ndi mipando yachitsulo,Valavu yolumikizira mpweya wachilengedweapangidwa ndikugwiritsidwa ntchito kwambiri. Kuwonjezera pa makhalidwe a ma valve a pulagi opangidwa ndi mafuta wamba, ma valve a pulagi ogwirizana ndi kupanikizika ali ndi makhalidwe awa:
- 1. Chophimba cha valavu yolumikizidwa bwino ya pulasitiki yolumikizidwa bwino imayikidwa pamalo opindika. Pali valavu yoyang'anira pamwamba pa chophimba. Chophimba chikatsekedwa, chifukwa cha kusiyana kwa malo odulidwa pamwamba ndi pansi pa chophimba, mafuta otsekera omwe amalowetsedwa amachititsa kuti chophimba chikwezedwe mmwamba, kuti chophimba chikhale ndi pamwamba pa chotseka chikhale chotsekedwa bwino.
- 2. Pamene valavu yatsegulidwa, kupanikizika m'chipinda chapansi cha thupi la valavu kumayenderana ndi kupsinjika kwapakati mu payipi. Mafuta otsekera opanikizika kwambiri m'chipinda chapamwamba amachititsa kuti thupi la pulagi likankhidwe pansi, ndipo mpata pang'ono umawonekera pakati pa phula ndi pamwamba pa thupi la valavu, mphamvu ya thupi la pulagi yozungulira imachepa bwino.
Zinthu zazikulu za valavu yolumikizidwa ndi pulasitiki yachilengedwe
Makhalidwe ndi ubwino waValavu yolumikizira mpweya wachilengedwe
- 1. Chogulitsachi chili ndi kapangidwe koyenera, kusindikiza kodalirika, magwiridwe antchito abwino komanso mawonekedwe okongola.
- 2. Ili ndi kapangidwe kake ka mphamvu yolumikizirana bwino komanso yoyatsa/kuzima pang'onopang'ono.
- 3. Mzere wa mafuta umayikidwa pakati pa thupi la valavu ndi pamwamba pa chisindikizo, zomwe zingalowetse mafuta otsekera kuti awonjezere mphamvu yotsekera.

Kugwiritsa ntchito valavu yolumikizira mafuta ya gasi wachilengedwe
Valavu yolumikizira mpweya wachilengedweimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga mafuta, makampani opanga mankhwala, mankhwala, feteleza, makampani opanga magetsi ndi zina zotero. Imagwiritsidwa ntchito pansi pa mphamvu ya CLASS150-1500LBS, ndipo imagwira ntchito pa kutentha kwa -40~450°C, Madzi, Gasi, Nthunzi ndi Mafuta ndi zina zotero.
