Hoʻohana ʻia kēia huahana moʻo i kahi ʻano hoʻopaʻa ʻano lana hou, pili i ke kaomi ʻaʻole i ʻoi aku ka nui ma mua o 15.0 MPa, ka mahana - 29 ~ 121 ℃ ma ka pipeline aila a me ke kinoea, e like me ka wehe ʻana a me ka pani ʻana o ka mīkini a me ka hoʻoponopono ʻana, ka hoʻolālā ʻana o ka huahana. , koho i nā mea kūpono, ka ho'āʻo koʻikoʻi, ka hana maʻalahi, ka anti-corrosion ikaika, ka pale ʻana i ka ʻaʻahu, ka pale ʻana i ka erosion, He mea hana hou ia i ka ʻoihana ʻaila.

1. Adopt floating valve noho, elua-ala wehe a pani, hilinaʻi sealing, hikiwawe wehe a pani.

2. Aia ka ʻīpuka i kahi pahu alakaʻi e hāʻawi i ke alakaʻi pololei, a ua kāpī ʻia ka ʻili o ka sila me ka carbide, ʻo ia ka pale ʻana.

3. He kiʻekiʻe ka hiki o ke kino valve, a pololei ke kahawai. Ke wehe piha ia, ua like ia me ka puka alakaʻi o ka ʻīpuka a me ka paipu pololei, a he liʻiliʻi ke kūʻē ʻana o ke kahe. Hoʻohana ka valve stem i ka hoʻopili pū ʻana, ka hoʻopaʻa ʻana he nui, e hilinaʻi ai ka sila, liʻiliʻi ka friction.

4. I ka wā e pani ai i ka valve, e hoʻohuli i ka huila lima ma ke ʻano uaki, a neʻe ka puka i lalo i lalo. Ma muli o ka hana o ke kaomi maʻamau, ua hoʻokuʻu ʻia ka noho sila ma ka ʻaoʻao inlet i ka ʻīpuka, e hana ana i kahi kaomi kikoʻī sealing nui, pēlā e hana ai i kahi sila. e lilo i sila papalua.

5. Ma muli o ke sila pālua, hiki ke pani ʻia nā ʻāpana palupalu me ka ʻole o ka hoʻopili ʻana i ka hana o ka pipeline.

6. I ka wehe ʻana i ka puka, e hoʻohuli i ka huila lima ma ka ʻaoʻao ʻē aʻe, e neʻe ana ka puka i luna, a pili ka puka alakaʻi me ka puka ala. Ke hiki aku i ka palena palena, ua like ka puka alakai me ka puka kanal, a ua hamama loa ia i keia manawa.
