Mu ntchito za m'nyanja, ma valve a bronze nthawi zambiri amaonedwa kuti ndi abwino kuposa ma valve a bronze chifukwa cha kukana dzimbiri komanso kulimba kwawo m'malo ovuta komanso amchere.
Zifukwa Zazikulu Zomwe Ma Valves Amkuwa Alili Abwino Kugwiritsa Ntchito M'madzi
1. Kukana Kwambiri Kudzimbiritsa
Malo okhala m'nyanja amadziwika kuti ndi owononga chifukwa chokumana ndi madzi amchere nthawi zonse. Ma valve amkuwa amalimbana kwambiri ndi dzimbiri la madzi amchere, okosijeni, ndi kuphulika, zomwe zimawonjezera nthawi yawo ya moyo. Izi zili choncho chifukwa bronze imapangidwa ndi mkuwa ndi tin, kuphatikiza komwe kumadzipangitsa kuti azipirira dzimbiri mwachilengedwe.
Koma ma valve amkuwa amakhala ndi zinc, zomwe zimapangitsa kuti zikhale zosavuta kuchotsa zinc. Izi zimachitika pamene zinc imachotsedwa mu alloy, zomwe zimasiya mkuwa wofooka komanso wofooka womwe ungasweke mosavuta ukapanikizika.
2. Mphamvu Yowonjezereka ndi Kulimba
Ma valve amkuwa amadziwika ndi mphamvu zawo zamakaniko komanso kulimba kwawo, zomwe zimapangitsa kuti akhale abwino kwambiri kugwiritsa ntchito zombo pamavuto amphamvu komanso kutentha kwambiri. Kutha kwawo kupirira nyengo zovuta kumatsimikizira kuti amagwira ntchito bwino pakapita nthawi.
Mosiyana ndi zimenezi, ma valve amkuwa ndi ofewa ndipo amatha kupindika kapena kusweka mosavuta akapanikizika kwambiri, zomwe zimapangitsa kuti asadalire kwambiri makina ofunikira monga kuziziritsa injini kapena makina oziziritsira madzi.
3. Kuchotsa Zinc ndi Kukhulupirika kwa Zinthu Zachilengedwe
Chimodzi mwa zoopsa zazikulu zogwiritsa ntchito mkuwa m'malo ozungulira nyanja ndi kuwononga mphamvu ya madzi, zomwe zingayambitse kulephera kwa ma valavu ndi kutuluka kwa madzi. Ma valavu amkuwa sakhudzidwa ndi vutoli, zomwe zimapangitsa kuti akhale otetezeka komanso olimba kwambiri pazinthu zofunika.
Ma valve a mkuwa angakhale oyenera kugwiritsa ntchito mitsinje yamadzi oyera kapena kugwiritsa ntchito zinthu zopanda mphamvu, koma pa mapaipi amadzi amchere kapena makina oziziritsira injini, bronze ndiye chisankho chomwe chimakondedwa.
4. Kutalika kwa nthawi ndi kugwiritsa ntchito bwino ndalama
Ngakhale ma valve amkuwa amatha kukhala ndi mtengo wokwera pasadakhale, nthawi yawo yayitali komanso zosowa zochepa zosamalira zimapangitsa kuti azikhala otchipa pakapita nthawi. Kusintha pang'ono ndi nthawi yochepa yosamalira zimathandiza kuti ntchitoyo isungidwe bwino.
Ma valve a mkuwa, ngakhale kuti poyamba ndi otsika mtengo, angafunike kusinthidwa pafupipafupi chifukwa cha dzimbiri, zomwe zimapangitsa kuti ndalama ziwonjezeke pakapita nthawi.
