Kupangidwa Zitsulo Kwathunthu Kuwotcheretsedwa Mpira Valve

thupi lake ndi limodzi welded cholumikizidwa ndi awiri hemispherical, mbali valavu ndi gawo gawo thupi bwino mu anakhazikitsa imodzi, nthawi yomweyo ali ndi mphamvu pazipita ndi kulemera osachepa, ndi mphamvu pazipita kukana kwa chitukuko chitoliro kuthamanga ndi kuthamanga, gawo gawo thupi valavu kapangidwe kupewa thupi cholumikizidwa ndi flange, motero kuchepetsa valavu mawonekedwe kukula ndi anathetsedwa kutsutsa njira, kupewa mankhwala poipoini ndi mwayi kuchokera kutsutsa kunja kwa mpira valavu ndi chifukwa chosafunika chilengedwe chiwon Moyo ungakhale zaka 20.

Makhalidwe a mankhwala:

1. Thupi ntchito yabwino kupanga zitsulo, onetsetsani kuti palibe mabowo, mphuka etc mavuto khalidwe.

2. Kuwana kwabwino ndi dzimbiri.

3. Double chipika ndi mwazi ntchito, pamwamba ndi pansi mbali ya mpando kupanga madzi chipika, thupi kusunga kutulutsa kudzera kutulutsa vavu.

5. Tsegulani mwamsanga ndi bwino.

6. Compact kapangidwe, kulemera kwaulemu, yaing'ono kutalika malangizo.

7. The spherical kutseka mbali akhoza basi kupeza pa malire malo, ndipo akhoza kupirira mkulu kuthamanga kusiyana pamene kutseka.

8. Pamene otseguka kwathunthu ndi kutsekedwa kwathunthu, kusindikiza nkhope ya mpira ndi mpando mosiyanasiyana ndi pakati.

9. Kukhala ndi kayendedwe ka madigiri 90, mpira uli ndi bwalo kudzera mu boko kudzera m'mphepete, khomo la mpira lonse limachepetsa kukana kwapakati, kuwonjezera njira yoyendera.

10. Valve mapeto akhoza kuwonjezera mapaipi.

11. Akhoza kudika ntchito, nthambo akhoza kuwonjezera malinga ndi zofunikira polojekiti, kuika mafuta oyenerana, madzi ogwiritsa ntchito ndi ventilating chipangizo amakhala ndi chubu anawonjezera pansi.

Kugwiritsa ntchito:

Zimagwira ntchito pa: mankhwala, mafuta, mpweya wachilengedwe, zitsulo, ndi mafakitale ena ndi mankhwala omwe ali ndi hydrogen sulfide, zoipa, dzimbiri zolimba za mpweya.
