Ma valve a mpira ndi zinthu zofunika kwambiri zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana powongolera kapena kuwongolera kutuluka kwamadzi ndi mpweya. Amapereka maubwino ambiri kuposa mitundu ina ya mavavu, monga valavu ya mpira wonyezimira, valavu ya mpira wa Spears, ndikudzipatula mpira valve.Tiyeni tione ubwino umenewu mwatsatanetsatane.
Valve Yathunthu Yowotcherera Mpira:Mavavu a mpira woyezeredwa kwathunthu adapangidwa kuti azipereka mphamvu zapamwamba komanso kulimba. Kumanga thupi lopangidwa ndi welded kumathetsa kufunikira kwa bolting kunja, kuchepetsa chiopsezo cha kutayikira ndikuwonetsetsa kuti moyo ukhale wautali. Mavavuwa amalimbana kwambiri ndi dzimbiri, kuwapangitsa kukhala abwino kugwiritsidwa ntchito m'malo owononga. Kuonjezera apo, kusakhalapo kwa njira zowonongeka kumawonjezera chitetezo chonse ndi kudalirika kwa valve.
socket weld mpira valve:Chimodzi mwazinthu zazikulu za valavu ya socket weld mpira ndi kulumikizana kwake. Thupi la valve ndi mapaipi amalumikizidwa ndi kuwotcherera, kupereka kulumikizana kwamphamvu komanso kodalirika. Kulumikizana kotsekemera kumeneku kumatha kupirira kuthamanga kwambiri komanso kutentha kwambiri ndikuchita bwino kusindikiza.
