1. Njira ndi malo
Ma valve ambiri ali ndi malangizo, monga valve stop, valve throttle valve, valve reduction valve, valve check valve, etc. Ngati atayikidwa mosiyana, zotsatira za utumiki ndi moyo wautumiki zidzakhudzidwa, kapena sizingagwire ntchito konse, kapena ngakhale kuyambitsa ngozi. Kwa ma valve ambiri, pali chizindikiro chowongolera pa thupi la valve. Ngati sichoncho, valavu idzadziwika bwino malinga ndi mfundo yake yogwirira ntchito. Malo oyika valavu ayenera kukhala abwino kuti agwire ntchito.
2. Ntchito yomanga
Kuyika ndi kumanga kuyenera kusamala kuti musamenye valavu yopangidwa ndi zinthu zowonongeka.
Musanakhazikitse, fufuzani mosamala ngati chitsanzo ndi ndondomeko ya ma valve onse akukwaniritsa zofunikira za mapangidwe.
Panthawi yoyikapo, pokweza valavu, chingwe sichimangiriridwa pa gudumu lamanja kapena tsinde, kuti zisawonongeke zigawozi, ndipo zidzamangidwa pa flange.
3. Njira zodzitetezera
Ma valve ena ayeneranso kukhala ndi chitetezo chakunja, chomwe ndi kuteteza kutentha ndi kuzizira. Nthawi zina payipi yosakanikirana ndi nthunzi yotentha imawonjezedwa pagawo la insulation. Ndi valavu yamtundu wanji yomwe iyenera kukhala insulated kapena kuzizira, malinga ndi zofunikira zopanga.
4. Kulambalala ndi zida
Ma valve ena, kuwonjezera pa zofunikira zotetezera, amakhalanso ndi bypass ndi zida. Bypass yakhazikitsidwa. Zosavuta kukonza valavu ya drain. Ma valve ena alinso ndi ma bypass valves. Kaya kuyika bypass kumadalira momwe ma valve alili, kufunikira kwake komanso zofunikira zopanga.
5. Kulongedza m'malo
Kufufuza kwa mavavu, kulongedza kwina kwakhala kovuta kugwiritsa ntchito, ena pogwiritsa ntchito media sikugwirizana, zomwe zimafuna m'malo mwa kulongedza.
