ʻO ka pahu pahu honua i hoʻopaʻa ʻiaHe kiwi poʻo honua me nā bellow metala elastic kiʻekiʻe a me ke ola luhi telescopic lōʻihi. Ke hoʻohana nei i ka hoʻolālā seal bellows, e hoʻopau loa i ka pauku valve stem packing seal aging leakage shortcomings, ʻaʻole wale e hoʻomaikaʻi i ka hoʻohana ʻana i ka ikehu pono, hoʻonui i ka palekana o nā lako hana, hoʻemi i nā kumukūʻai mālama a me ka mālama pinepine ʻana, akā hāʻawi pū kekahi i kahi kaiapuni hana maʻemaʻe a palekana.

Nā hiʻohiʻona hoʻolālā o

1. Hoʻolālā sila ʻelua (bellows + packing) Inā hāʻule ka bellows, e pale pū ʻia ka hoʻopili ʻana.

2. Hoʻolālā kūpono, hoʻopaʻa hilinaʻi, hana maikaʻi, hiʻohiʻona nani.

3. ʻAʻohe kahe wai, hoʻemi i ka nalowale o ka ikehu, hoʻomaikaʻi i ka palekana o nā mea kanu.

4. ʻO ka sealing surface surfacing Co based hard alloy, ʻaʻahu kūʻē, corrosion kū'ē, friction kū'ē, lōʻihi lawelawe ola, hoemi i ka helu o ka mālama 'ana, ho'ēmi i ka hana koina.

5. ʻO ka hoʻolālā sila ʻana o ka bellows e hōʻoiaʻiʻo i ka leaka ʻana o ke kumu a ʻaʻohe mālama.

6. E hooki i ka valve stem conditioning a me ka nitriding treatment surface, he maikai ka corrosion resistance a me ka friction resistance;

7. ʻOi aku ka intuitive intuitive o ka valve stem lifting position.

 Laulā o ka noi

He kūpono ka Bellows seal globe valve no ka petroleum, chemical, pharmaceutical, fertilizer chemical, mana uila a me nā ʻoihana ʻē aʻe ma lalo o nā kūlana hana like ʻole o ka pipeline, i hoʻohana ʻia e ʻoki a hoʻokomo ʻia i loko o ka pipeline medium.
