ʻO Bellows seal gate valves, he mea nui ia o ka bellows metala, ʻo ke kumu lalo e hoʻohana i ka wili wili a me ke kuʻi ʻana, ʻo ka ʻōwili luna a me ka pā pili i ka hoʻopili ʻana, ma waena o ka wai a me ka lewa e hana i kahi pale metala, e hōʻoia i ka ʻōpala o ka pahu. ʻole leakage.
2. ʻO ka hoʻolālā sila ʻelua (ʻo ka paipu corrugated + packing) inā hāʻule ka bellows, e pale pū ka paʻi ʻana i ka leaka a mālama i nā kūlana hoʻopaʻa inoa honua;
3. Hoʻopili ʻia ka uhi valve me ka momona, hiki ke hoʻohana pololei ʻia e lubricate i ke kumu, ka nut a me ka lima lima, ʻaʻole e like me ka lubrication screw maʻamau.
4. Ergonomically i hoʻolālā ʻia ka huila lima, me ka lōʻihi o ke ola lawelawe, maʻalahi a maʻalahi ka hana, palekana a ʻoi aku ka hilinaʻi;
Hoʻohana huahana: ka ʻaila, ka ʻoihana kemika, ka lāʻau lapaʻau, ka mea hoʻomomona, ka mana uila a me nā ʻoihana ʻē aʻe.
Mea: ke kila hoʻolei ʻia, ke kila hoʻoheheʻe ʻia, ke kila kila ANSI mea.
