Hoʻohana nui ʻia nā valve hoʻoponopono e hoʻoponopono i ke kahe a me ke kaomi o ka waena. Me ka hoʻoponopono valve, throttle valve, pressure reducing valve, etc.

Hoʻohana ʻia nā kiwi hoʻopaʻa no ka pale ʻana i ke kahe ʻana i hope. Loaʻa i nā kiwi hoʻopaʻa o nā hale like ʻole.

Hoʻohana ʻia nā kiwi shunt e hoʻokaʻawale, puʻunaue a hui pū paha i ka media. Me nā ʻano hana like ʻole o nā puʻupuʻu hoʻohele a me nā pahele, etc.

Hoʻohana ʻia nā kiwi palekana no ka pale ʻana i ka palekana i ka wā e hoʻomāhuahua ʻia ka mea waena. Me nā ʻano ʻano ʻokoʻa palekana palekana.

Hoʻokaʻawale ʻia e nā ʻāpana nui

(1) Hoʻokaʻawale ʻia e ke kaomi

ʻO kahi valve nona ke kaomi hana ʻoi aku ka haʻahaʻa ma mua o ke kaomi lewa maʻamau.

ʻO ka pahu haʻahaʻa haʻahaʻa he pahu nona ka PN nominal i emi iho ma mua o 1.6MPa.

ʻO ke kaomi inoa o ka valve kaomi waena he PN2.5 ~ 6.4MPa.

ʻO ke kiʻekiʻe kiʻekiʻe kiʻekiʻe ke kaomi inoa o PN10.0 ~ 80.0MPa.

ʻO ka valve puʻe kiʻekiʻe kiʻekiʻe he valve nona ka nui o ke kaomi PN ma mua o 100MPa.

(2) Hoʻokaʻawale ʻia e ka wela waena

ʻOi aku ka nui o ka valve wela ma mua o 450C.

ʻOi aku ka liʻiliʻi o ka valve wela 120C ma mua o ka valve nona ka t ma lalo o 450C.

ʻO ka valve wela maʻamau -40C ka liʻiliʻi ma mua o ka 120C.

ʻOi aku ka liʻiliʻi o ka valve wela haʻahaʻa -100C ma mua o ka -40C.

ʻOi aku ka liʻiliʻi o ka valve wela haʻahaʻa loa ma lalo o -100C.

(3) Hoʻokaʻawale ʻia e nā mea kino valve

ʻAʻole metala nā kiwi: e like me nā kiwi seramika, nā kiwi kila aniani, nā kiwi plastik.

ʻO nā ʻūhā mea metala: e like me nā kīwī keleawe keleawe, nā kīwaha alumini alumini, nā kīwaha alakaʻi alakaʻi, nā kīwaha titanium alloy, nā kīwaha monel alloy

Na kiwi hao, kiwi hao kalapona, kiwi kila, kiwi kila ha'aha'a, ki'eki'e.

ʻO nā kiwi hoʻopaʻa kino kiwi metala: e like me nā kiwi alakaʻi, nā kiwi i hoʻopaʻa ʻia i ka plastik, a me nā kiwi enamel.
