2. Valavu yoyendetsa galimoto: kudalira anthu, magetsi, hydraulic, pneumatic, ndi mphamvu zina zakunja kuti zigwiritse ntchito valve.Monga valavu yapadziko lonse lapansi, valavu yamagetsi, valavu yachipata, valavu ya disc, valavu ya mpira, valavu yamapulagi, ndi zina zotero.
II.Malingana ndi maonekedwe apangidwe
1. Kutseka mawonekedwe: chidutswa chotseka chimayenda pakatikati pa mpando.
2. Chipata mawonekedwe: chidutswa chotseka chimayenda motsatira mzere wapakati perpendicular kwa mpando.
3. Pulagi mawonekedwe: chidutswa chotsekera ndi plunger kapena mpira womwe umazungulira kuzungulira mzere wake wapakati.
4. Mawonekedwe otseguka: chidutswa chotseka chimazungulira mozungulira kunja kwa mpando.
5. Mawonekedwe a disc: membala wotseka ndi chimbale chomwe chimazungulira mozungulira mkati mwa mpando.
6. Valavu yotsegula: gawo lotsekera limasunthira molunjika ku njira.
III.Malinga ndi ntchito
1. Poyatsa/kuzimitsa: amagwiritsidwa ntchito podula kapena kulumikiza sing'anga ya mapaipi.Monga valavu yoyimitsa, valavu yachipata, valavu ya mpira, valavu yamapulagi, ndi zina zotero.
2. Zosintha: zomwe zimagwiritsidwa ntchito posintha kupanikizika kapena kuyenda kwa sing'anga.Monga valavu yochepetsera kuthamanga, ndi valavu yowongolera.
3. Pakugawa: amagwiritsidwa ntchito kusintha njira yoyendetsera yapakati, ntchito yogawa.Monga tambala wanjira zitatu, valavu yoyimitsa njira zitatu, ndi zina zotero.
4. Kuti muwone: amagwiritsidwa ntchito kuteteza media kuti zisabwererenso.Monga ma cheke ma valve.
5. Chifukwa cha chitetezo: pamene kuthamanga kwapakati kupitirira mtengo wotchulidwa, tulutsani mopitirira muyeso kuti muwonetsetse chitetezo cha zipangizo.Monga valavu chitetezo, ndi valavu ngozi.
6. Pakutsekereza gasi ndi ngalande: sungani mpweya ndikupatula condensate.Monga valavu ya msampha.
IV.Malinga ndi ntchito njira
1. Valavu yamanja: mothandizidwa ndi gudumu lamanja, chogwirira, lever, sprocket, gear, nyongolotsi, etc., gwiritsani ntchito valve pamanja.
2. Vavu yamagetsi: yoyendetsedwa ndi magetsi.
3. Vavu ya pneumatic: ndi mpweya woponderezedwa kuti ugwiritse ntchito valve.
4. Valavu ya hydraulic: mothandizidwa ndi madzi, mafuta, ndi zakumwa zina, tumizani mphamvu zakunja kuti zigwiritse ntchito valve.
V. Malinga ndikupanikizika
1. Vacuum valve: valavu yokhala ndi mphamvu yocheperapo kuposa 1 kg/cm 2.
2. Valavu yotsika: kuthamanga kwadzina kosachepera 16 kg / masentimita 2 valve.
3. Vavu yapakati yapakati: kuthamanga kwadzina 25-64 kg / masentimita 2 valve.
4. Vavu yothamanga kwambiri: kuthamanga kwadzina 100-800 kg / masentimita 2 valve.
5. Kuthamanga kwambiri: kuthamanga mwadzina kupita kapena kupitirira 1000 kg/cm 2 mavavu.
VI.Malinga ndikutenthawa sing'anga
1. Vavu wamba: yoyenera valavu yokhala ndi kutentha kwapakati pa -40 mpaka 450 ℃.
2. Vavu yotentha kwambiri: yoyenera valavu yokhala ndi kutentha kwapakati pa 450 mpaka 600 ℃.
3. Vavu yosamva kutentha: yoyenera valavu yokhala ndi kutentha kwapakati pa 600 ℃.
4. Valavu yotsika: yoyenera valavu yokhala ndi kutentha kwapakati pa -40 mpaka -70 ℃.
5. Vavu ya Cryogenic: yoyenera valavu yokhala ndi kutentha kwapakati pa -70 mpaka -196 ℃.
6. Vavu yotsika kwambiri ya kutentha: yoyenera valavu yokhala ndi kutentha kwapakati pa -196 ℃.
VII.Malinga ndi m'mimba mwake mwadzina
1. Vavu yaing'ono yaing'ono: m'mimba mwake mwadzina zosakwana 40 mm.
2. Vavu yapakati yapakati: m'mimba mwake mwadzina 50 mpaka 300 mm.
3. Ma valve akulu awiri: awiri mwadzina la 350 mpaka 1200 mm.
4. Mavavu a m'mimba mwake owonjezera: madiresi odziwika kwambiri kuposa 1400 mm.
