Nzila yakusala vvalavu ya globe—TWS Valve

Mavalvu aa globe alabelesyegwa kapati alimwi alijisi misyobo minji. Misyobo mipati njakuti, mavwili aa globe aa bellows, ma flange globe valve, internal thread globe valve, stainless steel globe valve, DC globe valve, needle globe valve, Y-shaped globe valve, angle globe valve, etc. type globe valve, heat preservation globe valve, cast steel globe valve, forge steel globe valve; mbokusala musyobo nchintu chipati, chiyandika kusalwa kweendelana abube bwachiimo, kupya, kusinikizyigwa abukkale bwakubeleka. Milawu yakusala ili boobu:

1. Ivalavu ya globe ye muuya yeelede kusalwa aamupayipi naakuti chibelesyo chili achiindi chilamfu loko. Mbuli mapaipi aapya kapati alimwi aajisi nguzu kapati mumaanda aapanga nguzu zyakupya alimwi anzila zyakupanga mafuta;

2. Ivalvu ya globe iizwa munzila iiluleme yeelede kubelesegwa mumupaipi aawo zyeelelo zyakukazya muya zitakatazyi pe;

3. Ivalvu ya nsingo, ivalvu yazibelesyo, ivalvu yakusampula, ivalvu yakupima muya, azimwi zilakonzya kubelesegwa ku valvu nsyoonto ya pneumatic globe;

4. Kuli kuchincha kweenda kwamaanzi naakuti kuchincha kwanguzu, pesi ziyandikana kuti kube kuchincha kabotu tazili zinji pe, mpawo bupati bwamupayipi mbuniini. Mbuli chitondeezyo, aamupaipi uulaa bupati bwa ≤50mm, nkubotu kubelesya vvalavu yakulesya muuya antoomwe a vvalavu yeendelezya magesi;

5. Kuti ujane nzila nguba yakuyuma, sala nzila yakukwabilila kupya;

6. Kubusena bujisi muya mupati loko, mavalvu aajisi nyika aapangidwe ayelede kusalwa;

7. Manyolo masyoonto alimwi amanyolo mapati mukupanga zintu zyakupanga-panga zyeelede kusala vvalavu ya globe ya pressure mpati naa throttle valve iijisi nguzu zya PN160 nominal pressure 16MPa naa PN320 nominal pressure 32MPa;

8. Mumulimo wakugwisya silikoni alimwi amapaipi aakonzya kuvwumbililwa munzila ya alumina Bayer, nchuubauba kusala vvalavu iizwa mujulu naa vvalavu iizwa mujulu iijisi mubili wa vvalavu uumbi, chibbula cha vvalavu chikonzya kugwisigwa, antoomwe a sementi ya carbide sealing pair;

9. Mumapulojekiti aakupa maanzi akupyasya mumaanda aamudolopo, nzila iibelesyegwa njiiniini, mpawo vvalavu yakujala muuya, vvalavu yakubamba naa vvalavu ya plunger ilakonzya kusalwa, mbuli chitondeezyo, nzila yamukati ilimunsi a 150mm.

10. Nkubotu kusala bbola lyakuzwa kunze lyanyika lya high temperature busi alimwi azintu zikola alimwi azintu zikonzya kuleta ntenda.

11. Ku vvalavu ya acid-base globe, sala vvalavu ya globe yabutale butakwe tombe naakuti vvalavu ya globe iijisi fluorine.
