Pahu Turbine Manual Flange Centerline Butterfly Valve

ʻO ka papa inoa nui o ka Balve Butterfly

Ma ke ʻano hoʻokele:
(1) Puka lele lele uila
(2) Pneumatic butterfly valve
(3) ʻO ka valve lele hydraulic
(4) Puka lele lele lima

Ma ka Papa Hana:
(1) Kiwikā lele lele waena
(2) Hoʻokahi eccentric sealing butterfly valve
(3) ʻelua eccentric sealing butterfly valve
(4) Triple eccentric sealing valve lele

Ma muli o nā mea i hoʻopaʻa ʻia i ka ʻili:
(1) Puka lele lele sila palupalu
(2) Metala paʻa paʻa paʻipaʻi pelelele valve

Ma ka Palapala Sila:
(1) Hoʻopaʻa paʻa ʻia ka pahu lele lele
(2) Pīwī lele lele paʻi
3

Ma ke kaomi hana:
(1) Puka lele lele.ʻO ka valve butterfly nona ka haʻahaʻa haʻahaʻa ma mua o ka puʻe lewa maʻamau.
(2) Haʻahaʻa puʻupuʻu lele lele.ʻO ke kīpē pēpē me ke kaomi inoa PN<1.6MPa.
(3) ʻO ka valve lele lele.ʻO ka pahu pelekane me ke kaomi inoa PN o 2.5--6.4MPa.
(4) kiʻekiʻe kiʻekiʻe pēpē pēpē valve.ʻO ka pahu pelekane me ke kaomi inoa PN o 10.0--80.0MPa.
(5) Puka lele lele kiʻekiʻe kiʻekiʻe.ʻO ke kīpē pēpē me ke kaomi inoa PN>100MPa.

Ma ka wela hana:
(1) Kiʻekiʻe wela.ʻO ka pahu pelekane no ka t>450 °C.
(2) Kiwi lele lele.120 C
(3) Puka lele lele wela maʻamau.A 40C
(4) Cryogenic butterfly valve.He 100
(5) Cryogenic butterfly valve.t<-100 °C kiwi lele.

Ma ke ala pili:
1. Wafer butterfly valve
Hoʻokomo ʻia ka pā papale o ka valve wafer butterfly ma ke anawaena o ka pipeline.Ua hāmama loa ka valve.
He ʻano maʻalahi ke ʻano o ka wafer butterfly valve, liʻiliʻi a me ke kaumaha māmā.He ʻelua ʻano hoʻopaʻa hoʻopaʻa ʻana i nā kiwi kīpē: elastic sila a me ke sila metala.No nā kiwi hoʻopaʻa elastic, hiki ke hoʻokomo ʻia ke apo sealing ma ke kino valve a i ʻole e hoʻopili ʻia i ka ʻaoʻao o ka pā butterfly.
2. Puka lele lele
ʻO ka valve butterfly flange he ʻano pāpaʻi kūpaʻa, a ʻo ke kumu valve ka apo hoʻopaʻa ʻana o ka pahu hoʻohui metala paʻa paʻa.
He ʻano hui ia o ka pā graphite maʻalahi a me ka pā kila kuhiliʻole, i hoʻokomo ʻia ma ke kino valve, a ʻo ka ʻili hoʻopaʻa ʻana o ka pā pepeke e uhi ʻia me ke kila kila.Hana ʻia ke apo hoʻopaʻa ʻana o ka valve seal soft i ka nitrile rubber a hoʻokomo ʻia ma luna o ka pā lele.
3. Lug type butterfly valve
4. Weled butterfly valve
