6 mau ʻano o ka valve butterfly sealing palupalu

Ma keʻano he mea i hoʻohanaʻia no kaʻikeʻana i ka mana on-off a me ke kahe o ka pipeline system, ua hoʻohana nuiʻia ka valve butterfly i hoʻopaʻaʻia i nāʻano he nui e like me ka petroleum, kaʻoihana kemika, ka metallurgy, ka hydropower a pēlā aku.Hoʻokomo ʻia ka disiki o ka valve butterfly sealing ma ka ʻaoʻao kū pololei o ka pipeline.Ma ka ʻaoʻao cylindrical o ke kino valve butterfly, e hoʻohuli ʻia ka pā peʻapeʻa ʻano diski a puni ke axis, a ʻo ke kihi o ka huli ʻana ma waena o 0° a me 90°.Ke hoʻololi ʻo ia i 90 °, ua wehe piha ka valve.

1. Hoʻokaʻawale ʻia ma ka hoʻopaʻa ʻana i nā mea ili

1) ʻO ka pāpaʻi pulupulu sealing palupalu: ʻO ka hoʻopaʻa ʻana i haku ʻia me nā mea palupalu non-metallic i nā mea palupalu non-metallic.

2) Metala paʻakikī sealing butterfly valve: ʻO ka hui hoʻopaʻa paʻa i haku ʻia me nā mea paʻakikī metala a me nā mea paʻakikī.

2. Hoʻokaʻawale ʻia ma ke ʻano

1) Kiwikā lele lele waena

2) Hoʻokahi eccentric sealing butterfly valve

3) ʻelua eccentric sealing butterfly valve

4) Triple eccentric sealing valve lele

3. Hoʻokaʻawale ʻia ma ke ʻano hoʻopaʻa

1) Hoʻopaʻa paʻa ʻia ka valve butterfly: Hana ʻia ka sealing e ka pā valve e kaomi ana i ka noho valve i ka wā i pani ʻia ai ka valve, a me ka elasticity o ka noho valve a i ʻole ka pā valve.

2) Applied torque sealing butterfly valve: hana ʻia ka sealing e ka torque i hoʻopili ʻia i ka pahu valve.

3) Pressurized sealing butterfly valve: Hoʻopuka ʻia ka sealing e ka hoʻopiʻi ʻana i ka mea elastic sealing element ma ka noho valve a i ʻole ka pā valve.

4) ʻO ka valve butterfly sealing aunoa: hoʻokumu ʻia ka sealing e ke kaomi waena.

4. Hoʻokaʻawale ʻia e ke kaomi hana

1) Vacuum butterfly valve: butterfly valve nona ka ha'aha'a o ka hana ma mua o ke kaomi lewa ma'amau.

2) Haʻahaʻa haʻahaʻa puʻupuʻu lele: lele lele me ke kaomi inoa PN<1.6MPa.

3) Medium pressure butterfly valve: he butterfly valve me ka nominal pressure PN o 2.5 a 6.4MPa.

4) Ke kiʻekiʻe kiʻekiʻe kiʻekiʻe papale valve: butterfly valve me ka nominal pressure PN o 10.0 a 80.0MPa.

5. Hoʻokaʻawale ma ke ʻano pili

1) Wafer butterfly valve

2) ʻO ka valve lele lele

3) Lug butterfly valve

4) Weled butterfly valve

6. Hoʻokaʻawale ʻia e ka mahana hana

1) Kiʻekiʻe wela wela lele valve: >450 ℃

2) Medium wela lele valve: 120 ℃

3) Puka lele lele maʻamau: -40 ℃

4) Haʻahaʻa wela lele valve: -100 ℃

5) Uila-ha'aha'a wela lele valve: <-100 ℃
