Vavu ndi gawo lowongolera mu njira yotumizira madzimadzi. Ndi mankhwala opangidwa ndi makina omwe amayendetsa kayendedwe ka madzi, kuthamanga ndi kayendedwe ka kayendedwe kake posintha kukula kwa dera lake. Pali mitundu yambiri ya ma valve, ndipo valve yotsika kwambiri ndi mtundu womwe umagwiritsidwa ntchito mobwerezabwereza. Kodi kuthamanga kwa valve yotsika-pressure ndi chiyani? Nkhaniyi imabweretsa kuchuluka kwa kuthamanga komanso kugawanika kwa ma valve otsika! Ndikuyembekeza kukuthandizani!
1¡¢ Kodi kuthamanga kwa valve yotsika kwambiri
Nthawi zambiri, magawo ogawa ndi 1.6Mpa ndi 10.0MPa. The otsika-anzanu payipi ndi amene ali ndi mamangidwe kuthamanga zosakwana kapena wofanana 1.6Mpa, sing'anga kuthamanga payipi ndi amene ali ndi mapangidwe kuthamanga kuposa 1.6Mpa ndi zosakwana kapena wofanana 10.0MPa, ndi payipi mkulu-anzanu. ndi yomwe ili ndi mphamvu yapangidwe yokulirapo kapena yofanana ndi 10.0MPa. Chitoliro chopondereza chimatanthawuza mapaipi onse omwe ali ndi mphamvu yamkati kapena yakunja, mosasamala kanthu za sing'anga mu chitoliro.
Kupanikizika kwa ma valve kungathenso kusiyanitsa ndi izi
1. Low kuthamanga mapaipi injiniya kuthamanga
2. Kuthamanga kwa mapaipi apakati apakati amagwira ntchito ndi 1.6-6.4mpa
3. Kuthamanga kwapaipi yapaipi yaukadaulo> 10MPa
Vavu yothamanga kwambiri ———– kuthamanga mwadzina PN ¡Ý 100MPa;
Vavu yothamanga kwambiri ———– kuthamanga mwadzina PN10 0 ~ 80.0MPa;
Vavu ya MP ———– kuthamanga mwadzina pN2 5 ~ 6.4MPa;
Vavu yotsika kwambiri ———– kuthamanga mwadzina PN ¡Ü 1.5MPa
2¡¢ Kuthamanga kwapakati ndi gulu la kalasi ya valve low pressure valve
1. Vacuum valve: valve yokhala ndi mphamvu
2. Vavu yotsika kwambiri: valavu yokhala ndi kuthamanga kwadzina PN ¡Ü 1.6Mpa (kuphatikiza valavu yachitsulo yokhala ndi PN ¡Ü 1.6Mpa)
3. Vavu yapakati yapakati: kuthamanga kwadzina pN2 5-6.4mpa valve.
4. Valavu yapamwamba: kuthamanga kwadzina PN10 0-80.0mpa valve.
5. Vavu yothamanga kwambiri: valve yokhala ndi mphamvu yodziwika PN ¡Ý 100.0mpa.
