ʻO ka flange maʻamau aupunikiwi pōkāhiki ke hoʻololi i 90 degere a pani paʻa me kahi torque liʻiliʻi. Ua like loa nā lua o loko o ka valve, e hāʻawi ana i kahi kū'ē liʻiliʻi a me kahi ala kahe pololei no ka mea waena. ʻO ka valve ball flanged maʻamau o ka mokuʻāina he hale paʻa a maʻalahi ke hana a mālama. He kūpono nā kīpē pōleʻa Flanged no nā media hana maʻamau e like me ka wai, nā solvents, nā waikawa a me ke kinoea maoli, a me nā media me nā kūlana hana paʻakikī, e like me ka oxygen, hydrogen peroxide, methane, a me ka ethylene. Hiki ke hoʻohui a hui pū ʻia ke kino valve.

ʻO ka flange maʻamau aupunikiwi pōkāHe paʻa i ka hana, maʻalahi ka hana a mālama, kūpono no ka pāpaʻi hana maʻamau e like me ka wai, solvent, acid a me ke kinoea maoli, a he mau kūlana hana koʻikoʻi (e like me ka hydrogen peroxide), a kūpono hoʻi no ka media. Hiki ke hoʻohui a hui pū ʻia nā kino kīpē pōlele e like me ka methane a me ka ethylene. Pono e hoʻokomo ʻia kēlā mau valves ma ka ʻaoʻao o ka pipeline.

ʻO nā pōmaikaʻi o ka ʻāina maʻamau flanged ball valve

1. He li'ili'i ke kū'ē o ka wai, a 'a'ohe kahe kū'ē o ka pahu piha piha.

2. Hoʻolālā maʻalahi, liʻiliʻi a me ke kaumaha māmā.

3. Pili a hilinaʻi. ʻElua mau ʻili hoʻopaʻa. ʻO kēia manawakiwi pōkāhoʻohana nui ʻia nā mea ʻili o ka sila i loko o nā plastics like ʻole, a loaʻa iā lākou kahi hana hoʻopaʻa maikaʻi, hiki ke hoʻokō i ka sila piha. Hoʻohana nui ʻia ia i nā ʻōnaehana vacuum.

4. ʻO ka hana maʻalahi, ka wehe wikiwiki a me ka paniʻana, pono wale e hoʻololi i ka 90 ° mai ka wehe pihaʻana i ka pani piha, kahi kūpono no ka mana mamao.

5. Maikaʻi ka mālama ʻana, maʻalahi ke ʻano o ka pahu pōpō, a me ke apo sealing maʻamau, maʻalahi e wehe a hoʻololi.

6. Ke wehe piha a pani ʻia paha, ua hoʻokaʻawale ʻia ka ʻili o ka sila a me ka noho valve mai ka waena. ʻOiai ke hele ka mea waena, ʻaʻole e ʻino ka ʻili o ka valve sealing.

7. ʻO ke anawaena mai kekahi mau millimeters a hiki i kekahi mau mika, a he nui kona mau noi, a hiki ke hoʻohanaʻia ma lalo o ke kiʻekiʻe kiʻekiʻe i ke kaomi kiʻekiʻe.

8. No ka mea, he mau hiʻohiʻona ka holoi ʻana o ka ʻōleʻa pōleʻa i ka wā e wehe ai a pani ʻia, hiki ke hoʻohana ʻia no ka media me nā ʻāpana paʻa paʻa.
