mavavu a mpira a block awiri ndi a mwazi

The Double Block ndi Bleed Isolation Philosophy imafuna mavavu awiri osakanizira m'mzere ndi mavavu osakanizira, ogwiritsidwa ntchito kutentha kapena kutentha madzi okhala pakati pa zinthu ziwiri zotseka kuti atheke chitetezo chitetezo chitoliro cha pansi. Mbali imeneyi ikhoza kukwaniritsidwa ndi mavavu amodzi c / w doko la mwazi pakati pa obturators.

MAKHALA:

• Anti kuphula kunja / otsika mpweya mitundu
• Kutetezeka kwa moto & kapangidwe odana ndi static
• Mpira wodziwika ndi nthengo
• Zitsulo zodzikhazikitsa
• Self kuchepetsa / awiri pisitoni zotsatira
mipando yoyamba
• Zofewa kapena zitsulo zokhala

Kapangidwe kulipo m'mbali kulowa, (bolted, kuwotcherera thupi) ndi pa nyanja, nyanja (pamwamba mbali) kapena pansi pa nyanja makonzedwe.
Bleed / Vent dongosolo akhoza kuperekedwa ndi Globe, Gate kapena Ball mavavu malinga ndi makasitomala zofuna.
