N’chifukwa chiyani muyenera kusankha valavu yowonera? Kodi pali mitundu yanji ya mavalavu?

Ma valve owonera pang'onopang'ono akhala zofunikira kwambiri pakupanga mapaipi ndi ma valve pakupanga mapaipi apano. Amapereka chitsimikizo chachitetezo cha mapaipi onse ndipo amachepetsa mwanjira ina zoopsa ndi ndalama zachitetezo pamakina onse apaipi.

Ma valve owonera amagwiritsidwa ntchito poyang'anira momwe zinthu zikuyendera nthawi yeniyeni, kuthetsa mavuto ndikuwonetsetsa kuti zinthu zili bwino. Ma valve owonera omwe amagwiritsidwa ntchito nthawi zambiri (monga magalasi owonera molunjika ndi zizindikiro zoyendetsera madzi) salamulira kayendedwe ka madzi okha, koma amapereka zenera lowoneka bwino pa payipi.

Ubwino wa kuyang'anira ma valve umaonekera makamaka m'mbali zitatu:

1. Yang'anani mwachindunji momwe madzi, mpweya, nthunzi ndi zinthu zina zimayendera, mtundu ndi kukhuthala kwa madzi, mpweya, ndi zina zomwe zili mu payipi.
2. Pamene dongosololi likumana ndi kuyenda kosazolowereka, kutsekeka kapena kusayenda bwino, chifukwa chake chingadziwike mwachangu kudzera mu valavu yowonera kaya ndi chifukwa cha valavu yokha yomwe yakhala ikutsekeka, kugwa kwa valavu pakati, kapena mavuto mu payipi yopita kumtunda.
3. Onetsetsani kuti dongosololi likugwira ntchito bwino. M'malo oopsa monga zomera za mankhwala, limagwiritsidwa ntchito kuyang'anira zinthu zotentha kwambiri, zowononga kwambiri komanso zofewa mosavuta kuti zisawonongeke chifukwa cha madzi abodza kapena kutsekeka.

Ma valve osiyanasiyana owonera amagwiritsidwa ntchito m'malo osiyanasiyana ogwirira ntchito. Opangidwa ndi chitsulo cha kaboni, ndi oyenera kugwiritsidwa ntchito pazinthu wamba monga madzi, nthunzi, ndi mafuta, koma sagonjetsedwa ndi dzimbiri.

Chitsulo chosapanga dzimbiri

Ndi chinthu chomwe chimagwiritsidwa ntchito kwambiri kuti chisawonongeke ndi dzimbiri ndipo chimagwiritsidwa ntchito m'njira zosiyanasiyana zowononga.

Chitsulo cha aloyi ndi zipangizo zapadera zosapanga dzimbiri

Yoyenera malo ovuta monga kutentha kwambiri, kuthamanga kwambiri, komanso dzimbiri lamphamvu.

Yophimbidwa ndi pulasitiki kapena fluorine

Yoyenera zinthu zowononga kwambiri monga ma asidi amphamvu ndi ma alkali amphamvu.

So

• Zosawononga: Chitsulo cha kaboni ndi chosankha komanso chotsika mtengo.
• Chofala kwambiri chowononga: Chitsulo chosapanga dzimbiri cha 304 kapena 316 ndicho chimakondedwa.
• Zowononga kwambiri kapena zapadera: Ma valve okhala ndi fluorine kapena ma alloy apadera amafunika.
• Chophimba kutentha kwambiri kapena chotentha pang'ono: Chitsulo chapadera chotentha kwambiri kapena chotentha pang'ono chiyenera kusankhidwa.
