DIN3202 Hoʻolei ʻia i ka ʻīpuka hao hao

ʻO ka valve puka e pili ana i ka valve nona ka ʻāpana pani (puka) e neʻe ana ma ke ala kū pololei o ka laina waena o ke kahawai.Hoʻohana nui ʻia ka valve puka no ka ʻoki ʻana i ka pipeline.ʻO ke kiwi puka kila forged he valve hoʻohana nui ʻia.Hoʻohana maʻamau ia no ka ʻoki ʻana i nā mea me ke anawaena o DN ≥ 50mm, a i kekahi manawa hoʻohana ʻia ka valve puka no ka ʻoki ʻana i nā mea me kahi anawaena liʻiliʻi.ʻO ka valve puka, ma ke ʻano he valve haʻahaʻa, ʻoi aku ka maʻamau.
Nā hiʻohiʻona o ka puka pā:
ʻO ka hana hoʻopaʻa ʻana maikaʻi, ke kūpaʻa wai liʻiliʻi a me kekahi hana hoʻoponopono;Eia nō naʻe, he nui kona nui, ʻano paʻakikī, ka hana paʻakikī, ʻaʻahu maʻalahi o ka ʻili o ka sila, paʻakikī ka mālama ʻana a me ka lōʻihi o ka wehe ʻana a me ka pani ʻana.He kūpono ia no ka hana ʻana i nā valves nui-diameter.Ma waho aʻe o ka mahu, ka aila a me nā mea hoʻolaha ʻē aʻe, kūpono ia no ka media i loaʻa nā paʻa granular a me ka viscosity kiʻekiʻe, a me nā valves no ka hoʻokuʻu ʻana a me nā ʻōnaehana haʻahaʻa haʻahaʻa.
