valavu ndi chipangizo makina amene amalamulira otaya, malangizo, kuthamanga, kutentha, etc. akuyenda madzimadzi sing'anga. Valve ndi gawo lofunikira mu dongosolo la mapaipi. Zopangira ma valve ndizofanana mwaukadaulo monga mapampu ndipo nthawi zambiri amakambidwa ngati gulu losiyana. Ndiye mitundu ya mavavu ndi chiyani? Tiyeni tione limodzi.
Pakadali pano, njira zomwe zimagwiritsidwa ntchito kwambiri padziko lonse lapansi komanso zapakhomo ndi izi:
1. Malingana ndi mawonekedwe ake, akhoza kugawidwa motsatira njira yosuntha ya membala wotseka wachibale ndi mpando wa valve:
1. Mawonekedwe a chipata cha gawo: Chidutswa chotseka chimayenda pakati pa mpando wa valve.
2. Maonekedwe a chipata: Chidutswa chotsekera chimayenda pakati pa mpando wa valve woyima.
3. Tambala ndi mpira: Gawo lotsekera ndi plunger kapena mpira, womwe umazungulira pakati pake.
4. Swing mawonekedwe; chidutswa chotseka chimazungulira mozungulira kunja kwa mpando wa valve.
5. Mawonekedwe a mbale: Chimbale cha membala wotseka chimazungulira mozungulira pampando wa valve.
6. Mawonekedwe a valavu: Chidutswa chotseka chimayenda molunjika ku njira.
2. Malinga ndi njira yoyendetsera galimoto, imatha kugawidwa m'njira zosiyanasiyana:
1. Zamagetsi: Zoyendetsedwa ndi ma motors kapena zida zina zamagetsi.
2. Hydraulic: yoyendetsedwa ndi (madzi, mafuta).
3. Mpweya; gwiritsani ntchito mpweya woponderezedwa kuti muyendetse valavu kuti mutsegule ndi kutseka.
4. Buku: Mothandizidwa ndi gudumu lamanja, chogwirira, lever kapena sprocket, ndi zina zotero, zimayendetsedwa ndi anthu ogwira ntchito, ndipo pamene mpweya wotumizira uli waukulu, uli ndi zida za nyongolotsi, zida ndi zipangizo zina zochepetsera.
Atatu, malinga ndi cholinga, malinga ndi zolinga zosiyanasiyana za valavu akhoza kugawidwa mu:
1. Pothyoka: amagwiritsidwa ntchito kulumikiza kapena kudula zoulutsira mapaipi, monga mavavu a globe, mavavu a pachipata, ma valve a mpira, ma valve agulugufe, ndi zina.
2, kugwiritsidwa ntchito kosabwerera: kumagwiritsidwa ntchito kuteteza sing'anga kuti isabwerere mmbuyo, monga valavu.
3, kusintha: kumagwiritsidwa ntchito kusintha kupanikizika ndi kutuluka kwa sing'anga, monga valavu yowongolera, valavu yochepetsera kuthamanga.
4. Kugawa: amagwiritsidwa ntchito kusintha kayendedwe ka kayendedwe kapakati ndikugawa sing'anga, monga tambala wa njira zitatu, valve yogawa, slide valve, etc.
5. Valve yachitetezo: Pamene kupanikizika kwa sing'anga kumaposa mtengo wotchulidwa, kumagwiritsidwa ntchito kutulutsa sing'anga yowonjezereka kuti zitsimikizire chitetezo cha makina opangira mapaipi ndi zipangizo, monga ma valve otetezera ndi ma valve odzidzimutsa.
6. Zolinga zina zapadera: monga misampha, ma valve otulutsa mpweya, ma valve otayira, ndi zina.
