Hoʻolauna i ka noi, nā mea nui a me nā ʻano hoʻonohonoho o ka valve hōʻoia papa pālua wafer

Waferpā pāluakiwikā nānāʻO ia hoʻi ka valve e wehe a pani koke ana i ka ʻaoʻao valve ma ka hilinaʻi ʻana i ke kahe o ka medium ponoʻī e pale aku i ke kahe hope o ka medium, i ʻike ʻia hoʻi ʻo check valve, one-way valve, reverse flow valve a me back pressure valve. Waferpā pāluakiwikā nānāhe kiwikā ʻakomi nona ka hana nui e pale i ke kahe hope o ka medium, pale i ka hoʻohuli hope ʻana o ka pamu a me ka motika hoʻokele, a hoʻokuʻu i ka medium i loko o ka pahu. Waferpā pāluaHiki ke hoʻohana ʻia nā kiwikā nānā ma nā laina e hoʻolako ana i nā ʻōnaehana kōkua kahi e piʻi ai ke kaomi ma luna o ke kaomi o ka ʻōnaehana.

1. Ka noi ʻana o ka valve nānā pālua ʻano Wafer:

Waferpā pāluakiwikā nānāua hoʻokomo ʻia i loko o ka ʻōnaehana pipeline, a ʻo kāna hana nui ka pale ʻana i ke kahe hope o ka medium. ʻO ka waferpā pāluakiwikā nānāhe kiwikā ʻakomi ia e wehe ʻia a pani ʻia ma muli o ke kaomi waena. ʻAno Waferpā pāluakiwikā nānākūpono no ke kaomi maʻamau PN1.0MPa ~ 42.0MPa, Papa 150 ~ 25000; ke anawaena maʻamau DN15 ~ 1200mm, NPS1 / 2 ~ 48; mahana hana -196 ~ 540 ℃ ma nā paipu like ʻole, hoʻohana ʻia e pale i ke kahe hope o ka medium. Ma ke koho ʻana i nā mea like ʻole, hiki ke hoʻopili ʻia i nā media like ʻole e like me ka wai, ka mahu, ka ʻaila, ka waikawa nitric, ka waikawa acetic, ka medium oxidizing ikaika a me ka waikawa uric.

2. ʻO ka mea nui o ka waferpā pāluakiwikā nānā:

Aia ke kila kalapona, ke kila haʻahaʻa haʻahaʻa, ke kila pae pālua (F51/F55), ka hui titanium, ke keleawe alumini, INCONEL, SS304, SS304L, SS316, SS316L, ke kila chrome molybdenum, Monel (400/500), 20# hui, Hastelloy a me nā mea metala ʻē aʻe.

3. Nā ʻano kūkulu opā pāluakiwikā nānā:

1. He pōkole ka lōʻihi o ke kūkulu ʻana, a ʻo kona lōʻihi kūkulu he 1/4 ~ 1/8 wale nō o ka flanged kuʻunaʻōniʻoniʻokiwikā nānā.

2. Ka liʻiliʻi a me ke kaumaha māmā, ʻo kona kaumaha he 1/4 ~ 1/20 wale nō o ka flanged kuʻunaʻōniʻoniʻokiwikā nānā.

3. Pani koke ka diski valve a liʻiliʻi ke kaomi o ka hāmare wai

4. Hiki ke hoʻohana ʻia nā paipu ākea a i ʻole nā ​​​​paipu kū pololei, maʻalahi e hoʻouka

5. He laumania ke kahawai kahe a he liʻiliʻi ke kūpaʻa wai

6. Hana koʻikoʻi a me ka hana sila maikaʻi

7. He pōkole ka hele ʻana o ka valve disc a he liʻiliʻi ka ikaika hopena pani

8. He maʻalahi a paʻa ka ʻōnaehana holoʻokoʻa, a he nani ke ʻano

9. Ke ola lawelawe lōʻihi a me ka hana hilinaʻi

ʻO ka hā, nā hewa maʻamau o kapā pāluaʻO nā valve hōʻoia:

1. Ua haki ka diski valve

ʻO ke kaomi o ka waena ma mua a ma hope o kapā pāluakiwikā nānāaia i ke kūlana o ke kaulike kokoke a me ka "ʻoki like". Hoʻopaʻa pinepine ʻia ka diski valve me ka noho valve, a ua paʻi ʻia ka disc valve i hana ʻia me kekahi mau mea palupalu (e like me ka hao i hoʻolei ʻia, keleawe, a me nā mea ʻē aʻe). haki.

ʻO ke ʻano pale ʻana, ʻo ia ka hoʻohana ʻana i kahipā pāluakiwikā nānā me kahi diski ma ke ʻano he mea ductile.

2. Kahe hope waena

Ua hōʻino ʻia ka ʻili sila; ua paʻa nā mea haumia.

Ma ka hoʻoponopono ʻana i ka ʻili sila a me ka hoʻomaʻemaʻe ʻana i nā mea haumia, hiki ke pale ʻia ke kahe hou.
