ʻO ka valve plug he valve rotary i ke ʻano o kahi pani a plunger paha. Ma hope o ka hoʻololi ʻana i nā degere 90, ua like ka wehe ʻana o ke kahawai ma ka plug valve me ka hoʻokaʻawale ʻana mai ka wehe ʻana o ke kahawai ma ke kino valve e hoʻopau i ka wehe a pani ʻana paha. Hoʻohana nui ʻia ia i ka ʻeli ʻana i ka ʻaila hinu, ka lawe ʻana a me ka hoʻomaʻemaʻe ʻana i nā mea hana, a pono hoʻi ia mau valves i nā mea kanu asphalt mixing.

Hiki ke ʻano cylindrical a i ʻole conical ka pahu pahu o ka pahu pahu i loko o ka mea kanu hui asphalt. I loko o ka pahu pahu cylindrical, ʻo ke kahawai maʻamau ʻehā; i loko o ka pahu pahu conical, he trapezoidal ke kahawai. Mālama kēia mau ʻano i ke ʻano o ka valve plug a kūpono loa no ka pale ʻana a me ka hoʻopili ʻana i ka media a me ka hoʻohuli.
Ma muli o ka neʻe ʻana o ka neʻe ʻana ma waena o nā wahi sealing o ka valve plug he hopena scrubbing, a i ka wā e wehe piha ai, hiki iā ia ke pale loa i ka hoʻopili ʻana me ka neʻe ʻana, no laila hiki ke hoʻohana maʻamau no ka media me nā mea i hoʻokuʻu ʻia. Eia kekahi, ʻo kahi hiʻohiʻona koʻikoʻi ʻē aʻe o ka valve plug he mea maʻalahi ia e hoʻololi i ka hoʻolālā multi-channel, i hiki i hoʻokahi valve ke loaʻa i ʻelua, ʻekolu, a i ʻole ʻehā mau kahawai kahe like ʻole, hiki ke maʻalahi i ka hoʻonohonoho ʻana o ka ʻōnaehana pipeline. , e ho'ēmi i ka nui o nā valves a me kekahi mau mea hoʻohui e pono ai i ka lako.
ʻO ka valve plug o nā mea kanu hui asphalt he kūpono ia no ka hana pinepine ʻana ma muli o kona wehe wikiwiki a maʻalahi hoʻi. Loaʻa iā ia nā mea maikaʻi o ke kūpaʻa wai liʻiliʻi, ke ʻano maʻalahi, ka liʻiliʻi liʻiliʻi, ke kaumaha māmā, ka mālama maʻalahi, ka hana hoʻopaʻa ʻana maikaʻi, ʻaʻohe vibration, a me ka leo haʻahaʻa.
Ke hoʻohana ʻia ka pahu pahu i loko o ka asphalt hui ʻana i nā mea kanu, ʻaʻole ia e kaohi ʻia e ke kuhikuhi o ka hāmeʻa, a ʻo ke ala kahe o ka mea waena hiki ke lilo i kekahi, e hoʻoikaika hou i kāna hoʻohana ʻana i nā lako. I ka ʻoiaʻiʻo, ma kahi o ka pae i ʻōlelo ʻia ma luna, hiki ke hoʻohana nui ʻia ka valve plug i ka petrochemical, chemical, coal gas, natural gas, liquefied petroleum gas, HVAC occupations a me ka ʻoihana maʻamau.
