Indlela yokukhetha i-globe valve—TWS Valve

Ama-valve e-globe asetshenziswa kabanzi futhi anezinhlobo eziningi. Izinhlobo eziyinhloko ama-valve e-globe e-bellows, ama-valve e-globe e-flange, ama-valve e-globe angaphakathi kwentambo, ama-valve e-globe ensimbi engagqwali, ama-valve e-globe e-DC, ama-valve e-globe anenaliti, ama-valve e-globe anomumo we-Y, ama-valve e-globe e-angle, njll. uhlobo lwe-valve ye-globe, i-valve ye-globe yokugcina ukushisa, i-valve ye-globe yensimbi ephothiwe, i-valve ye-globe yensimbi eyenziwe ngobumba; indlela yokukhetha uhlobo ibaluleke kakhulu, idinga ukukhethwa ngokwezici zesimo esiphakathi, izinga lokushisa, ingcindezi kanye nezimo zokusebenza. Imithetho ethile yokukhetha imi kanje:

1. I-valve ye-pneumatic globe kufanele ikhethwe epayipini noma kudivayisi yokushisa okuphezulu kanye ne-medium yokucindezela okuphezulu. Njengepayipi yokushisa okuphezulu kanye ne-high pressure ezitshalweni zamandla ezishisayo kanye nezinhlelo ze-petrochemical;

2. Ivalvu yeglobhu egeleza ngqo kufanele isetshenziswe epayipini lapho izidingo zokumelana nokuguquguquka kwe-convection zingaqinile;

3. Ivalvu yenaliti, ivalvu yethuluzi, ivalvu yokuthatha isampula, ivalvu yokulinganisa ingcindezi, njll. ingasetshenziswa kuvalvu encane yeglobhu yomoya;

4. Kukhona ukulungiswa kokugeleza noma ukulungiswa kwengcindezi, kodwa izidingo zokunemba kokulungiswa aziphezulu, futhi ububanzi bepayipi buncane kakhulu. Isibonelo, epayipini elinobubanzi obujwayelekile obungu-≤50mm, kungcono ukusebenzisa ivalvu yokumisa umoya kanye nevalvu yokulawula kagesi;

5. Ukuze uthole indlela yokuqinisa ikristalu elula ukuyiqinisa, khetha ivalvu yokuvala ukuvikela ukushisa;

6. Ezindaweni ezinengcindezi ephezulu kakhulu, kufanele kukhethwe amavalvu embulunga ahlanganisiwe;

7. Umanyolo omncane kanye nomanyolo omkhulu ekukhiqizweni kwezimboni zokwenziwa kufanele bakhethe i-globe valve ene-angle yokucindezela okuphezulu noma i-high pressure angle throttle valve ene-nominal pressure PN160 nominal pressure 16MPa noma i-PN320 nominal pressure 32MPa;

8. Eshabhu lokususa i-silicon kanye namapayipi ajwayele ukubhoboza enqubweni ye-alumina Bayer, kulula ukukhetha ivalvu yeglobe egeleza ngqo noma ivalvu ye-throttle egeleza ngqo enomzimba wevalvu ohlukile, isihlalo sevalvu esisuswayo, kanye nepheya lokuvala i-carbide eliqinisiwe;

9. Emaphrojekthini okuphakelwa kwamanzi nokushisa ekwakhiweni kwedolobha, indlela yokudlula ejwayelekile incane, kanti ivalvu yokuvala umoya, ivalvu yokulinganisela noma ivalvu ye-plunger ingakhethwa, isibonelo, indlela yokudlula ejwayelekile ingaphansi kuka-150mm.

10. Kungcono ukukhetha i-valve ye-globe ye-bellows engenisiwe ye-humusi oshisa kakhulu kanye nemidiya enobuthi neyingozi.

11. Ukuze uthole i-valve ye-globe ene-acid-base, khetha i-valve ye-globe yensimbi engagqwali noma i-globe ene-fluorine.
