Kodi valavu ya globe yolumikizidwa ndi chiyani?
Valavu yapadziko lonse yolumikizidwandi kapangidwe kapadera ka ma valve ang'onoang'ono padziko lonse lapansi.
Monga valavu ya globe, ili ndi mawonekedwe onse a valavu ya globe, imatsegula ndi kutseka mwachangu.
Ma valve. Monga mwachizolowezi, magawo otsegulira ndi otseka ndi chipata, okhala ngati wedge, ndichifukwa chake amatchedwa valavu ya chipata cha wedge. Njira yoyendetsera chipata ndi yolunjika ku mbali yamadzi. Vavu ya chipata cha wedge imatha kutsegulidwa kwathunthu ndikutsekedwa kwathunthu ndipo singasinthidwe ndikukankhidwa. Vavu ya chipata idapangidwa kuti igwiritsidwe ntchito potseguka kwathunthu kapena kutsekedwa kwathunthu.
komaValavu yapadziko lonse yolumikizidwaIli ndi mawonekedwe akeake. Yapangidwa ndi chitsulo cha kaboni chopangidwa ndi chitsulo chosapanga dzimbiri, chitsulo chosakanikirana ndi aloyi, yokhala ndi thupi laling'ono, yoyenera madzi othamanga kwambiri. Boneti ikhoza kulumikizidwa ndi boliti, kuwotcherera ndi kutsekedwa ndi kupanikizika, malinga ndi momwe ntchito ikuyendera.
Zinthu zazikulu za valavu ya globe yolumikizidwa
Zinthu zazikulu za API602valavu ya globe yachitsulo chopangidwa
- 1) Tsinde lokwera ndi ulusi wolondola wa acme wowirikiza kuti ligwire ntchito mwachangu.
- 2) Cholumikizira cha thupi kuchokera ku bonnet chomwe chimapangidwa kuti chigwiritse ntchito katundu wofanana pa gasket kuti chitsimikizire kuti palibe kutayikira kwa madzi.
- 5) Chipinda chakumbuyo chomwe chimapangidwa kuti chichepetse kupsinjika kwa kumbuyo kwa chivundikiro cha tsinde chikakhala pansi mokwanira. Sikoyenera kusintha chivundikiro cha tsinde pansi pa kupsinjika.
- 6) Kuyika tsinde la tsinde lapangidwa kuti liwongolere bwino kutulutsa kwa mpweya wotuluka mumlengalenga. Kuchuluka kwa kutuluka kwa mpweya wotuluka kumatsimikizika ndi kutha bwino kwa malo otsekera tsinde, kutsika kwa ma diametrical clearances komanso kuwongolera kulunjika kwa tsinde.
