Indlela yokukhetha i-globe valve—TWS Valve

Amavalvu we-globe asetjenziswa khulu begodu anemihlobo eminengi. Imihlobo ekulu ngamavalvu we-bellow globe, ama-flang globe valve, ama-internal thread globe valve, ama-stainless steel, ama-DC globe valve, ama-needle globe valve, ama-Y-shaped globe valve, ama-angle globe valve, njll. indlela yokukhetha umhlobo iqakatheke khulu, itlhoga ukukhethwa ngokuya ngeemfanelo zendawo, izinga lokutjhisa, umfutho kanye nobujamo bokusebenza. Imithetho ekhethekileko yokukhetha ilandelako:

1. Ivalvu ye-pneumatic globe kufanele ikhethwe ephayiphini nofana idivayisi enezinga lokutjhisa eliphezulu kanye nomfutho ophezulu. Njengamapayipi wezinga lokutjhisa eliphezulu kanye negandelelo eliphezulu eentjalweni zamandla womtjhiso kanye neenhlelo ze-petrochemical;

2. Ivalvu ye-globe egeleza ngqo kufanele isetjenziswe epayipini lapho iimfuneko zokujamelana nokudlulisa zingakaqini;

3. Ivalvu yenalithi, ivalvu yeensetjenziswa, ivalvu yokuthatha isampula, ivalvu yokulinganisa umfutho, njll.

4. Kunokulungiswa kokugeleza nofana ukulungiswa komfutho, kodwana iimfuneko zokulungisa ukunemba aziphezulu, begodu ububanzi bephayiphi buncani. Ukwenza isibonelo, ephayiphini enobubanzi obuncani obungu-≤50mm, kungcono ukusebenzisa ivalvu yokumisa ye-pneumatic kanye nevalvu yokulawula kagesi;

5. Ukuze kube lula ukuqina, khetha ivalvu yokuvala ukulondolozwa komtjhiso;

6. Eendaweni ezinomfutho omkhulu khulu, kufanele kukhethwe amavalvu we-globe akhiwe;

10. Kungcono ukukhetha i-valve ye-globe ye-bellows engeniswako ye-hizinga lokutjhisa eliphezulu kanye nemidiya enobuthi neyingozi.

11. Nge-esidi-base ye-globe valve, khetha i-stainless steel globe valve nofana i-globe valve ene-fluorine.
