He aha ka Bellows Seal Globe Valve?
ʻO Bellows Seal Globe Valve,hana maʻamau a hana ʻia e like me ke kūlana Kelemania a me ka maʻamau ʻEulopa EN13709. e like me ka mea maʻamau, ʻo ia ka linear motion pani-down valve i hoʻohana ʻia e hoʻomaka, hoʻōki a hoʻoponopono i ke kahe me ka hoʻohana ʻana i kahi lālā pani i kapa ʻia he disc.kaBellows Seal Globe valvesʻoi aku ka maikaʻi a hoʻohana nui ʻia e kāohi a hoʻōki i ke kahe ʻana o ka wai a i ʻole ke kinoea ma o ka paipu no ka throttling a me ka hoʻokele ʻana i ka kahe wai a hoʻohana mau ʻia i nā paipu liʻiliʻi.
ua hana ʻia e hoʻokō i nā koi koʻikoʻi o ka paʻa a me nā kūlana hana koʻikoʻi.bellows seal globe valveHe mea hoʻopili puʻupuʻu hoʻi. Aia ka ʻūhā accordion-like a hoʻopaʻa ʻia i loko o ka paipu metala mānoanoa.Me ka laula ākea o ka paipu i hoʻopaʻa paʻa ʻia i loko o ka pāpale o ka valve, aia kahi sila leak-leak.
Loaʻa i ka Bellows ke ola lawelawe, ʻo ia hoʻi ka hiki ke haki.ʻO ia ke kumu e hoʻokomo mau ʻia ai kahi hui hoʻopili maʻamau i loko o kahi pāpale i hoʻolako ʻia i ka bellows.
ʻO ka maʻamau, aia ʻekolu mau hiʻohiʻona kino a i ʻole hoʻolālā noBellows Seal Globe valves:
- 1). Kūlana Kūlana (e like me ka Tee Pattern a i ʻole T - Pattern a i ʻole Z - Pattern)
- 2).
- 3).Oblique Pattern (ʻike pū ʻia ʻo Wye Pattern a i ʻole Y - Pattern)
ʻO nā hiʻohiʻona nui o Bellows Seal Globe Valve?
Ma nā kaʻina hana kemika, ʻona pinepine nā wai i loko o nā paipu, radioactive a weliweli.Hoʻopaʻa ka Bellows i nā kiwi honuahoʻohana ʻia e pale aku i ka leaka ʻana o kekahi kemika ʻona i ka lewa.Hiki ke koho ʻia nā mea kino mai nā mea āpau i loaʻa, Hiki ke hāʻawi ʻia ka bellow i nā mea like ʻole e like me 316Ti, 321, C276 a i ʻole Alloy 625.
- 1) He nui nā mea hiki ke loaʻa ma keʻano maʻamau (streght pattern), Angle pattern, a me Wye pattern (Y pattern).
- 2). Hoʻopaʻa nā bellow metala i ke koʻokoʻo neʻe a hoʻonui i ka lōʻihi o nā pahu hoʻopaʻa sila.
- 3) Elua mau sila kumu lua: a) Noho hope ma ke kulana hamama;b) Hoʻopili graphite.
- 4). Ho'āʻo pinepine ʻia nā pahu i hoʻopaʻa ʻia ma lalo me ka spectrometer nui no ka ʻike ʻana i ka nui o ka leaka ma lalo o 1x10E-06 std.cc/sec. Hoʻolālā hoʻopaʻa paʻa (bellows seal and stem packing) inā hāʻule ka bellows, e pale pū ka pahu pahu pahu. leakage, a e like me nā kūlana paʻa honua;
- 5) .Easy Machining a me ka hoʻoulu houʻana o nā noho, no nā kumu likeʻole.
- 6) ..Short huakaʻi mamao o ka disc(stroke) ma waena o ka hamama a pani pani,Hoʻopaʻa ka Bellows i nā kiwi honuakūpono inā pono e wehe a pani pinepine ʻia ka valve;
- 7) Hoʻohana nui ʻia ma nā ʻāina āpau i ka hui ʻEulopa, a me kekahi mau ʻāina ʻē aʻe pū kekahi.
