Valavu yolumikizira yamagetsi yopangidwa ndi mafakitale ku China wopanga fakitale
Kodi valavu yolumikizira yopaka mafuta ndi chiyani?
Valavu yolumikizira yodzola Ili ndi dzenje pakati pa pulagi motsatira mzere wake. Mphepete iyi imatsekedwa pansi ndipo imayikidwa cholumikizira cholumikizira pamwamba. Cholumikizira chimayikidwa m'dzenjemo, ndipo valavu yowunikira pansi pa cholumikizira cholumikizira imaletsa cholumikizira kuti chisayende mobwerera m'mbuyo. Cholumikizira chimatuluka kuchokera pakati pa dzenjelo kudzera m'mabowo a radial kupita ku mipata yamafuta yomwe imatambalala kutalika kwa malo okhala pulagi.
Pofuna kuchepetsa mphamvu ya ma valve a pulagi opangidwa ndi mipando yachitsulo,ma valve opukutira mafutaapangidwa 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 pulagi
Makhalidwe ndi ubwino waKuthamanga kozungulira koyenera kofewa Valavu ya pulagi
- 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 yopaka mafuta
Valavu yolumikizira yodzolaimagwiritsidwa 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.
