300X valavu yotseka pang'onopang'ono

Makhalidwe a mankhwala

Valve yowunikira imapangidwa ndi valavu yayikulu ndi valavu yowongolera kunja. Pali zipinda ziwiri zamadzi mu valavu yayikulu, ndipo chipinda chamadzi cha diaphragm ndi chipinda chowongolera kuthamanga. Pampu yamadzi ikasiya kugwira ntchito, chifukwa cha kulemera kwake kwa valavu, mphamvu ya kasupe wamkulu wa valve ndi mphamvu ya kusiyana pakati pa chipinda chapamwamba ndi chipinda chapansi (pamene mpope wamadzi usiya kugwira ntchito, kupanikizika kumunsi kumunsi). chipinda chimachepetsa mofulumira, koma kuthamanga kwa chipinda chapamwamba kumachepa pang'onopang'ono), mbale ya valve imatsekedwa 90% mofulumira, ndipo 10% yotsalayo imaperekedwa ku chipinda chapamwamba ndi chitoliro chowongolera. Ndi kuwonjezeka kwa kupanikizika m'chipinda chapamwamba, chivundikiro cha valve chimatengedwa kuti chitseke chitseko chotseka Chotsalira 10% chotsegulira chimagwira ntchito yochepetsera phokoso ndi kuchepetsa nyundo ya madzi.

1. Iyenera kukhazikitsidwa mozungulira

2. Musanakhazikitse, ma sundries mkati mwa netiweki ya chitoliro ayenera kutsukidwa kuti atsimikizire kusuntha kosinthika kwapakati pa valve.

3. Valve yoyimitsa yokhala ndi m'mimba mwake yofananira idzayikidwa pamalo pomwe gwero la madzi lingathe kudulidwa pamene valavu yoyang'ana ikhoza kusungidwa.

4. Valve yowunikira iyenera kusungidwa yoyera mkati musanayambe komanso panthawi yotumiza mapaipi, ndipo sidzalowa m'malo osiyanasiyana chifukwa cha zomangamanga molakwika.

5. Kutumiza: pamene valavu ichoka ku fakitale, valavu ya singano ndi valavu ya mpira zonse zatsekedwa. Gwiritsani ntchito valavu ya wotchi kuti muzungulire mozungulira 2 ndi theka molunjika, ndipo valavu ya mpira imakhala yotseguka. Ngati nyundo yamadzi ipezeka, valavu yaing'ono ya mpira imatha kutsekedwa pang'ono, ndipo valavu ya jekeseni imatha kutsegulidwa pang'ono motsatana ndi nthawi kuti athetse nyundo yamadzi.
