Amavalvu emabubulweni ahlukahlukeneko emisebenzini ehlukahlukeneko, khulukhulu ephethroliyamu, i-petrochemical, amakhemikhali, i-metallurgy, amandla kagesi, ukongiwa kwamanzi, ukwakhiwa kwedorobha, umlilo, imitjhini, amalahle, ukudla nokunye (lapho, abasebenzisi bemboni yamakhemikhali namakhemikhali wemakethe yamavalvu batshwenyeke khulu ngeemfuneko zamavalvu nazo ziphezulu).
1, amavalvu wokufakwa kwamafutha
Iyunithi yokucoca amafutha. Inengi lamavalvu atlhogekako emayunithini wokucwengisisa amafutha ngamavalvu wamapayipi, khulukhuluivalvu yesangos, amavalvu we-globe, amavalvu wokuhlola, amavalvu wokuphepha, amavalvu webhola, amavalvu we-butterfly, iinthiyo. Hlangana nazo, ivalvu yesango itlhoga ukubalelwa ku-80% yenani elipheleleko lamavalvu, (amavalvu abalelwa ku-3% ukuya ku-5% wokutjala imali okupheleleko kudivayisi).
2、Amavalvu wokusebenzisa isitjalo samandla kagesi wamanzi
Ukwakhiwa kwesitjalo samandla se-China kuthuthuka ngendlela ekulu, njeke isidingo samavalvu wokuphepha amakhulu kanye nomfutho omkhulu, amavalvu wokwehlisa umfutho, amavalvu we-globe, amavalvu wesango,Amavalvu we-butterfly aqinileko,amavalvu wokuvimba ubujamo obuphuthumako kanye namavalvu wokulawula ukugeleza, amavalvu we-globe weensetjenziswa zokuvala eziyindilinga.
3、Ivalvu zokusetjenziswa kwensimbi
Ibubulo le-metallurgic ekuziphatheni kwe-alumina litlhogeka khulu ukujamelana nokuguga kwe-slurry valve (ekugelezeni kwe-globe valve), ukulawula iinthiyo. Ibubulo lokwenza insimbi litlhoga khulu amavalvu webhola avaliwe ngensimbi, amavalvu we-butterfly kanye namavalvu webhola le-oksijini, i-cut-off flash kanye namavalvu aqondisa ngeendlela ezine.
4, ivalvu yokusetjenziswa kwelwandle
Kulandele ukuthuthukiswa kwemayini yamafutha elwandle, inani leenhluthu zayo eziphaphathekileko zaselwandle ezitlhoga ukusebenzisa ivalvu likhuphuke kancanikancani. Amapulatifomu welwandle kufuze asebenzise amavalvu webholo wokuvala, amavalvu wokuhlola, amavalvu weendlela ezinengi.
5, ivalvu yokufaka ukudla nemithi
Ibubulo leli litlhoga khulu amavalvu webholo wensimbi engagqwali, amavalvu webhola weplastiki angenabuthi kanye namavalvu we-butterfly. Iinkoro ezili-10 ezingenhla zemikhiqizo yamavalvu, naziqathaniswa nenengi lokufunwa kwamavalvu asetjenziselwa ukusetjenziswa jikelele, njengamavalvu weensetjenziswa, amavalvu weenaliti, amavalvu we-needle globe, amavalvu wesango, amavalvu we-globe,ivalvu yokuhlolas, amavalvu webhola, amavalvu we-butterfly khulukhulu.
6, emaphandleni, amavalvu wokufuthumala wedorobha
Irherho lokufuthumala kwedorobha, litlhoga ukusebenzisa inani elikhulu lamavalvu we-butterfly avalwe ngensimbi, amavalvu wokulinganisa avundlileko kanye namavalvu webholo angcwatjhwe ngqo. Ngebanga lomhlobo lo wevalvu ukurarulula ukuphazamiseka kwepayipi ye-hydraulic, ukufezekisa ukonga amandla, ukukhiqizwa kwebhalansi yokutjhisa.
7, amavalvu wokusebenzisa amapayipi
Iphayiphi yebanga elide khulukhulu yamafutha ahlanzekileko, imikhiqizo eqediweko kanye namapayipi wemvelo. Umhlobo lo wepayipi utlhoga ukusebenzisa inengi lamavalvu wesimbi ekhwengisiweko anemizimba emithathu, amavalvu wesango le-anti-sulphur, amavalvu wokuphepha, amavalvu wokuhlola.
