Mawonekedwe a PVC manual double by-order mpira valve:
1. Valani kukana: Popeza valavu ya valve yotsekedwa mwamphamvu imakhala yopopera ndi zitsulo za alloy, ndipo mphete yosindikizira imakokedwa ndi chitsulo cha alloy, valve yotsekedwa mwamphamvu sichidzavala kwambiri pakusintha (kuuma kwachitsulo). coefficient ndi 65-70).
2. Ntchito yosindikiza ndi yabwino;chifukwa kusindikiza kwa valavu ya mpira wotsekedwa mwamphamvu kumapangidwira, mpaka pakati pa valve ndi mphete yosindikizira zikugwirizana kwathunthu.Kotero ntchito yake yosindikiza ndi yodalirika.
3. Chosinthira ndi chopepuka;popeza pansi pa mphete yosindikizira ya valve yotsekedwa mwamphamvu imagwiritsa ntchito kasupe kuti igwirizane mwamphamvu ndi mphete yosindikizira ndi chigawo cha valve, pamene mphamvu yakunja ikupitirira kudzaza kasupe, kusinthako kumakhala kowala kwambiri.
4. Moyo wautali wautumiki: Wagwiritsidwa ntchito kwambiri m’madipatimenti a petroleum, mankhwala, kupanga magetsi, kupanga mapepala, mphamvu ya maatomu, ndege, roketi, ndi madipatimenti ena, limodzinso ndi moyo watsiku ndi tsiku wa anthu.
