ʻO ke kahua hoʻohuihui asphalt kahi pūʻulu piha koʻikoʻi o nā lako i ke ola o nā kānaka. He nui nā ʻāpana o ka lako, e like me ka mīkini grading, vibrating screen, belt feeder, powder conveyor, elevator a me nā ʻāpana ʻē aʻe. ʻO ka valve plug kekahi o lākou. No laila he aha ke kuleana kūikawā o ka valve plug i ka mea kanu asphalt mixing? E hāʻawi kēia ʻatikala i kahi hoʻolauna pōkole ma hope.

ʻO ka valve plug ka mea mua o ka panina a i ʻole ka plunger-like rotary valve. ʻO ka mea maʻamau, pono e hoʻohuli ʻia he kanaiwa degere e hana i ke awa o ke kahawai ma ka pahu valve e like me ke kino valve, a i ʻole hiki ke māhele ʻia e wehe a pani paha. hopena. ʻO ke ʻano o ka valve plug i loko o kahi mea kanu asphalt mixing he cylinder a i ʻole cone.

Inā ʻike ka mea hoʻohana i kahi ala ʻehā i loko o kahi mea kanu hui asphalt, maʻamau ia i loko o kahi puʻupuʻu cylindrical valve. Inā he ala trapezoidal ia, he puʻupuʻu valve tapered. No ka valve plug, ʻo nā ʻano hana like ʻole e hoʻomaʻamaʻa i ka hale. ʻO ka hana nui ʻo ia ke ālai a hoʻopili paha i ka waena. ʻO ka hoʻohana ʻē aʻe e hoʻohuli i ke kahe.

He wikiwiki a maʻalahi hoʻi ka hana ʻana o nā pahu hoʻohui i nā mea kanu asphalt, no laila ʻaʻole pilikia ka hana pinepine ʻana. He mau hiʻohiʻona ʻē aʻe nā ʻāpana plug, e like me ke kūpaʻa wai liʻiliʻi, ke ʻano maʻalahi, ka mālama maʻalahi, ka hana sila maikaʻi a ʻaʻohe oscillation. ʻO ka walaʻau haʻahaʻa a me nā pono ʻē aʻe. ʻO ka hoʻohana ʻana i nā kīwī plug i loko o nā mea kanu hui asphalt ʻaʻohe pilikia kuhikuhi, no laila he akamai loa ka hoʻohana ʻana i nā mea hana.
