Valavu ndi chipangizo chamakina chomwe chimayang'anira kayendetsedwe ka kayendedwe ka kayendedwe kake, kuthamanga, kutentha, ndi zina zotero za sing'anga yamadzimadzi, ndi valavu 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 tifufuze limodzi.
Pakadali pano, njira zomwe zimagwiritsidwa ntchito kwambiri pakugawa ma valve padziko lonse lapansi komanso m'nyumba ndi izi:
1. Malinga ndi mawonekedwe ake, malinga ndi momwe membala wotseka amayenda molingana ndi mpando wa valve, akhoza kugawidwa kukhala:
1. Mawonekedwe odulidwa: gawo lotsekera limayenda pakati pa mpando wa valve.
2. Mawonekedwe a chipata: membala wotseka amayenda pakati pa mpando woyima.
3. Tambala ndi mpira: Membala wotseka ndi plunger kapena mpira umene umazungulira pakati pa mzere wake wapakati.
4. Swing mawonekedwe;membala wotseka amazungulira mozungulira kunja kwa mpando wa valve.
5. Mawonekedwe a Disk: diski ya membala wotseka imazungulira mozungulira pampando wa valve.
6. Mawonekedwe a valve otsegula: membala wotseka amasuntha molunjika ku njira.
2. Malinga ndi njira yoyendetsera galimoto, imatha kugawidwa motsatira njira zosiyanasiyana zoyendetsera:
1. Zamagetsi: zoyendetsedwa ndi mota kapena zida zina zamagetsi.
2. Mphamvu ya hydraulic: yoyendetsedwa ndi (madzi, mafuta).
3. Pneumatic: gwiritsani ntchito mpweya woponderezedwa kuti muyendetse valavu kuti mutsegule ndi kutseka.
4. Buku: Mothandizidwa ndi magudumu am'manja, zogwirira, levers kapena sprockets, ndi zina zotero, zimayendetsedwa ndi anthu.Potumiza torque yayikulu, imakhala ndi zida zochepetsera monga magiya a nyongolotsi ndi magiya.
3. Malingana ndi cholinga, malinga ndi ntchito zosiyanasiyana za valve, zikhoza kugawidwa mu:
1. Pothyoka: amagwiritsidwa ntchito kulumikiza kapena kudula sing'anga yamapaipi, monga valavu yapaipi, valavu yachipata, valavu ya mpira, valavu ya butterfly, ndi zina zotero.
2. Kwa osabwerera: amagwiritsidwa ntchito kuteteza kubwereranso kwapakati, monga valavu yowunika.
3. Zosintha: zomwe zimagwiritsidwa ntchito posintha kupanikizika ndi kutuluka kwa sing'anga, monga kuwongolera ma valve ndi ma valve ochepetsa mphamvu.
4. Kugawa: amagwiritsidwa ntchito kusintha kayendedwe ka kayendedwe kapakati ndikugawa sing'anga, monga matambala a njira zitatu, ma valve ogawa, ma slide valves, ndi zina zotero.
5. Valve yachitetezo: Pamene kupanikizika kwa sing'anga kumaposa mtengo wotchulidwa, kumagwiritsidwa ntchito kutulutsa sing'anga yowonjezereka kuti zitsimikizire chitetezo cha dongosolo la mapaipi ndi zipangizo, monga valavu yachitetezo ndi valve yodzidzimutsa.
6. Zolinga zina zapadera: monga misampha ya nthunzi, ma valve otsekemera, ma valve otayira, ndi zina zotero.
