ʻO ka hoʻohana ʻana a me nā hiʻohiʻona o ka pahu pahu wafer

一, hoʻohana:

Hoʻokomo ʻia ka valve check didlink i loko o ka ʻōnaehana pipeline, a ʻo kāna hana nui ka pale ʻana i ke kahe ʻana i hope. ʻO ka valve check he valve aunoa ia e pili ana i ke kaomi o ka mea waena e wehe a pani. He kūpono ka Wafer check valve no nā pipelines like ʻole me ke kaomi nominal PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, ke anawaena inoa DN15 ~ 1200mm, NPS1 / 2 ~ 48, ka mahana hana -196 ~ 540 ℃, e pale i ke kahe ʻana o ka waena. Ma ke koho ʻana i nā mea like ʻole, hiki ke hoʻohana ʻia i nā ʻano media like ʻole e like me ka wai, ka mahu, ka aila, ka waikawa nitric, ka waikawa acetic, ka media oxidizing ikaika, a me ka uric acid.

二, nā hiʻohiʻona hale:

1. He pōkole ka lōʻihi o ka hale, a ʻo kona lōʻihi he 1/4 ~ 1/8 wale nō o ka pahu hoʻokele flange maʻamau;

2. ʻO ka liʻiliʻi liʻiliʻi a me ke kaumaha māmā, ʻo kona kaumaha he 1/4 ~ 1/20 wale nō o ka valve check flange maʻamau;

3. Paʻa koke ke kīpulu a liʻiliʻi ke kaomi hāmare wai;

4. Hiki ke hoʻohana ʻia nā paipu ākea a me nā paipu kūpaʻa, a maʻalahi ke kau ʻana;

5. ʻAʻole pale ʻia ke kahawai kahe a liʻiliʻi ke kūpaʻa wai;

6. ʻO ka hana maʻalahi a me ka hana sila maikaʻi;

7. He pōkole pōkole a me ka hopena pani liʻiliʻi o ka disc valve;

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

9. ʻO ke ola lōʻihi a me ka hana hilinaʻi.
