Indlela yokukhetha ye-valve yeglobu—i-TWS Valve

Ama-valve e-globe asetshenziswa kabanzi futhi anezinhlobo eziningi. Izinhlobo eziyinhloko ama-valve embulunga evuza, ama-valve eglobhu e-flange, ama-valve eglowubhu yentambo yangaphakathi, ama-valve eglobhu ensimbi engenasici, ama-valve eglowubhu e-DC, ama-valve eglowubhu yenaliti, ama-valve eglobhu amise okuka-Y, ama-engeli eglobhu, njll. , i-valve ye-globe yensimbi eyinsimbi, i-valve yeglobu yensimbi ebunjiwe; indlela yokukhetha uhlobo ibaluleke kakhulu, idinga ukukhethwa ngokuvumelana nezici ze-medium, izinga lokushisa, ingcindezi kanye nezimo zokusebenza. Imithetho yokukhetha eqondile imi kanje:

1. Ivalvu yeglobhu yomoya kufanele ikhethwe epayipini noma kudivayisi yokushisa okuphezulu kanye nendawo yokucindezela okuphezulu. Okufana nokushisa okuphezulu kanye namapayipi okucindezela okuphezulu ezitshalweni zamandla ashisayo kanye nezinhlelo ze-petrochemical;

2. Ivalvu yeglobhu egeleza ngokuqondile kufanele isetshenziswe epayipini lapho izidingo zokumelana nokugeleza zingaqini;

3. I-valve yenaliti, i-valve yensimbi, i-valve yesampula, i-valve ye-gauge ye-pressure, njll ingasetshenziselwa i-valve encane yeglobhu yomoya;

4. Kukhona ukulungiswa kokugeleza noma ukulungiswa kwengcindezi, kodwa izidingo zokunemba kokulungiswa azikho phezulu, futhi ububanzi bepayipi buncane kakhulu. Isibonelo, epayipini elinobubanzi obungu-≤50mm, kungcono ukusebenzisa i-valve yokumisa umoya kanye ne-valve yokulawula kagesi;

5. Nge-crystallization medium okulula ukuyiqinisa, khetha i-valve yokuvala ukugcina ukushisa;

6. Ezindaweni ezinomfutho ophakeme kakhulu, amavalvu embulunga omgunyathi kufanele akhethwe;

7. Umanyolo omncane kanye nomanyolo omkhulu ekukhiqizeni izimboni zokwenziwa kufanele ukhethe i-valve ye-globe ye-high pressure angle noma i-high pressure angle throttle valve ene-pressure yegama elithi PN160 ingcindezi yegama elingu-16MPa noma i-PN320 ingcindezi yokulinganisa engu-32MPa;

8. Eshabhu yokukhipha insimbi kanye namapayipi athambekele ekuphekeni enqubweni ye-alumina Bayer, kulula ukukhetha i-valve yembulunga egeleza ngokuqondile noma i-throttle valve egeleza ngokuqondile enomzimba we-valve ohlukile, isihlalo se-valve esikhiphekayo, kanye nesimende. i-carbide sealing pair;

9. Emisebenzini yokuhlinzeka ngamanzi nokushisa ekwakhiweni kwedolobha, i-passage encane incane, futhi i-valve yokuvala umoya we-pneumatic, i-balance valve noma i-plunger valve ingakhethwa, isibonelo, i-passage encane ingaphansi kuka-150mm.

10. Kungcono ukukhetha i-valve yeglobe ye-bellows engenisiwe engu-hI-igh lokushisa umusi kanye nemidiya enobuthi neyingozi.

11. Ngevalvu yeglobu ye-acid-base, khetha ivalvu yeglobu yensimbi engagqwali noma ivalve yeglobu ene-fluorine.
