ʻO ka valve butterfly ventilation ka pahu e hele ai i ka lewa e hoʻoneʻe i ke kinoea. He maʻalahi a maʻalahi ka hana.

hiʻona:

1. He haʻahaʻa ke kumu kūʻai o ka valve butterfly ventilation, maʻalahi ka ʻenehana, liʻiliʻi ka torque i koi ʻia, liʻiliʻi ke kumu hoʻohālike, a ʻoi aku ka maikaʻi o ke kumukūʻai holoʻokoʻa;

2. ʻAʻole palena ʻole ka mahana. Hiki ke hoʻohana ʻia nā mea like ʻole ma ka mahana maʻamau (< 100 ℃), ka wela kiʻekiʻe (200 ℃ + -) a me ka wela kiʻekiʻe loa (500 ℃ + -);

3. ʻO ke ola lōʻihi, ka hana maʻalahi a me ka maʻalahi o ka mālama ʻana i ka valve butterfly ventilation;

4. Me ka nui o ka leakage, e hoʻohui i ke apo paʻa ma ka paia o loko o ke kino valve e hoʻopili pono i ka pā valve me ke apo paʻa i ka wā i pani ʻia ai ka pahu e hoʻemi i ka leakage, a hiki ke hoʻomalu ʻia ka leakage ma kahi o 1 %; no ka papahana hoʻomaʻemaʻe kinoea, aia i loko o ka mana hoʻomalu;

Ma muli o kēia mau hiʻohiʻona, ua ʻike nui ʻia ka valve butterfly ventilation, adsorption desorption, catalytic combustion a me nā papahana hoʻomaʻemaʻe kinoea ʻē aʻe e hoʻohana i kēia ʻano valve.

Hoʻokaʻawale ʻia o ka valve butterfly ventilation:

1. E like me ka pilina, hiki ke hoʻokaʻawale ʻia i flange, welding end a me wafer ends

2 .E like me ka mea, hiki ke hoʻokaʻawaleʻia i ke kila kila, ke kila kalapona a me ke kila kila

3. E like me ke ala hana, hiki ke hoʻokaʻawale ʻia i ka uila, manual, pneumatic a me ka hydraulic
