Nā hiʻohiʻona o ke kaula kila forged / socket welding globe valve
1. Loaʻa iā ia ka hana paʻa, hiʻohiʻona nani a me ke kahawai kahe hoʻemi. Nā hiʻohiʻona hoʻolālā: BB a i ʻole WB;
2. Hana ʻia ka ʻili hoʻopaʻa i ke kila kila a i ʻole ka carbide cemented. He kūpono ka hoʻohālikelike ʻana i nā mea hoʻopaʻa inoa a lōʻihi ke ola lawelawe;
3. He conical ka disc valve, a ua hāʻawi ʻia ka pahu valve me ke sila hoʻohuli ʻia, me ka hana hoʻopaʻa maikaʻi. ʻO ka ʻili o ke kumu valve he nitrided, nona ka pale corrosion maikaʻi a me ke kūpaʻa friction. Hoʻohana ka packing i ka graphite maʻalahi, me ka sila hilinaʻi, ka hana maʻalahi a me ka wehe liʻiliʻi a me ka torque pani;
4. Hiki ke koho ʻia nā kūlana paipu like ʻole a me nā ʻano pili (e like me ka wili socket, ka wili kī a me ka pilina pili).
ʻO ke kūlana hoʻokō no ke kaula hao hao / socket welding globe valve
