He aha ka SDV Valve?

Nā Kiwikā SDVhe ʻano lako palekana i hoʻohana pinepine ʻia i ka petrochemical, pharmaceutical, meaʻai a me nā ʻoihana ʻē aʻe a me nā kahua aila ma waho, ʻo ka inoa pihakiwikā pani, a ʻo ka inoa Kina ʻo cut off Valve a i ʻole Shut off valve. Eia kahi hoʻolauna kikoʻī i ka SDV valve:

ʻO ka haku mele a me ke ʻano o nā SDV Valves

ʻO ka valve SDV ka mea nui i hana ʻia me ʻelua ʻāpana: ka actuator a me ke kino valve. Loaʻa i ka actuator kahi piston, kahi pūnāwai a me kahi lima, a me kahi ʻāpana hoʻololi aunoa. He actuator pneumatic ia o ke ʻano wehe ea, a ua lako me kahi valve solenoid e wehe a pani paha i ke ala kinoea, kahi i hoʻohana ʻia e kāohi i ka wehe ʻana a i ʻole ka pani ʻana o ka valve.

ʻO ke kumumanaʻo hana o ka valve SDV

Hoʻokumu ʻia ke kumumanaʻo hana o ka valve SDV ma ka actuator pneumatic. Ma hope o ka loaʻa ʻana o ke kuhikuhi o ka ʻōnaehana FSC a i ʻole ka ʻōnaehana pani ulia pōpilikia (ESDV), wehe ʻia a pani ʻia paha ka valve ma ke kaohi ʻana i ka hoʻā ʻana a me ka hoʻopau ʻana o ke kumu ea i hoʻopaʻa ʻia ma o ka valve solenoid.

Hana a me ka hoʻohana ʻana o nā Valves SDV

ʻO ka valve SDV ke kuleana o ka pale ʻana i ka pani ʻana i ka pilikia i loko o ka ʻōnaehana, a aia ma ka pipeline puka o nā lako. Ke kū mai nā kūlana maʻamau, hiki iā ia ke ʻoki koke i ka loop kumu ea e pale ai i ke kahe ʻana o ka mea waena, a pēlā e hōʻoiaʻiʻo ai i ka palekana o ka ʻōnaehana.

Hoʻohana nui ʻia nā kiwikā SDV ma nā kahua ʻaila ma waho a me ka ʻoihana petrochemical ma uka. Ma nā kahua ʻaila ma waho, aia nā kiwikā SDV nui (e laʻa, ka nui o ka kiwikā ≥16 ʻīniha, ka papa paona ≥900LB) ma ka puka o ka mea hoʻokuʻu pōpō pigging a i ʻole ma ke komo ʻana o ka mea loaʻa pōpō pigging, a he mau lako palekana koʻikoʻi ia i ke kaʻina hana.

Nā ʻano a me nā pono

Loaʻa i ka valve SDV nā ʻano o ka mālama palekana, hilinaʻi a maʻalahi hoʻi o ka actuator pneumatic, kūpono loa no nā wahi pōʻino.

ʻO nā kiwikā SDV e wehe piha wale ʻia a pani piha ʻia, no laila ua ʻike ʻia hoʻi lākou he mau kiwikā ʻelua-kūlana. Hiki i kēia hoʻolālā ke hana maikaʻi i nā kiwikā SDV ke pono e ʻoki koke a pololei i ke kahe waena.

Iā Summery

Nā kiwikā SDVhe mea palekana koʻikoʻi ia e pāʻani ana i kahi hana koʻikoʻi i nā ʻoihana petrochemical, lāʻau lapaʻau, meaʻai a me nā ʻoihana ʻē aʻe, a me nā kahua aila ma waho. Hoʻomaopopo ia i ka hana wehe a pani paha ma o ka actuator pneumatic, loaʻa iā ia nā ʻano o ka palekana, ka hilinaʻi, ka mālama maʻalahi, a hiki ke ʻoki koke i ke kahe waena i ka wā pilikia e hōʻoia i ka palekana o ka ʻōnaehana.
