Ma nā kaʻina hana kemika, ʻona pinepine nā wai i loko o nā paipu, radioactive a weliweli.Bellows seal gate valveshoʻohana ʻia e pale i ka leaka ʻana o kekahi kemika ʻona i ka lewa.Hiki ke koho ʻia nā mea kino mai nā mea āpau i loaʻa, Hiki ke hāʻawi ʻia ka bellow i nā mea like ʻole e like me 316Ti, 321, C276 a i ʻole Alloy 625.

• 1). Hoʻopaʻa nā ʻūhā metala i ke kumu o ka neʻe ʻana a hoʻonui i ka lōʻihi o nā pahu hoʻopaʻa sila i hoʻopaʻa ʻia.
• 2) .Bellows monitor port (koho): Hiki ke hoʻopili ʻia kahi plug me kahi ākea ma luna o ka bellow e nānā i ka hana.
• 3) Elua mau sila kumu lua: a) Noho hope ma ke kulana hamama;b) Hoʻopili ʻana i ka graphite.
• 4).no Bellows seal gate valve, kona mau mea nui metala bellows, ka hope o lalo a me ka valve stem is automatic rolling welded, and the top end and the protection tube is automatic roll welded.Hoʻokumu ʻia kahi pale metala ma waena o ke kumu ma kona wahi e komo ai ma o ka palena kaomi a me ke kaʻina hana i loko o ka valve, e hoʻopau i ka leakage kumu;
• 5). Ho'āʻo pinepine ʻia nā pahu i hoʻopaʻa ʻia ma lalo me ka hoʻohana ʻana i ka spectrometer nui no ka ʻike ʻana i ka nui o ka leaka ma lalo o 1x10E-06 std.cc/sec. Hoʻolālā hoʻopaʻa paʻa (bellows seal and stem packing) inā hāʻule ka bellows, e pale pū ka pahu pahu pahu. leakage, a e like me nā kūlana paʻa honua;
• 6). Kākoʻo ʻia nā pāpale i hoʻopaʻa ʻia ma lalo me kahi hoʻonohonoho paʻi kumu maʻamau a me kahi awa nānā leakage ma waena o ka bellows a me ka hoʻopili ʻana i mea e pale ai i ka hoʻokuʻu ʻana o ka wai pōʻino i ka wā o ka leak bellows.
• 7) ʻAʻole like me ka wili hinu kahiko wale nō no ke kaula kumu, Ua hoʻolālā ʻia kahi nipple momona ma ka pāpale kiwi, hiki iā mākou ke lubricate i ka ʻōpala, ka nut a me ka bushing pololei, ma o ka nipple momona;
• 8) .Ergonomically i hoʻolālāʻia i ka lima lima,ʻoi aku ka lōʻihi o ka lawelaweʻana, maʻalahi ka hana, palekana aʻoi aku ka hilinaʻi;
