valavu yowongolera ya SV10-40 yokhala ndi malo awiri anjira zinayi

Mtundu

Pali mitundu yambiri ya ma valve oyendetsa ma valve olamulira, monga molunjika-kupyolera pa mpando umodzi, molunjika-kupyolera pa mpando wawiri, angular, diaphragm, kuyenda kochepa, njira zitatu, eccentric rotation, butterfly, manja ndi ozungulira. Pakusankhidwa kwapadera, malingaliro otsatirawa angaganizidwe:

1. Zimaganiziridwa makamaka molingana ndi zinthu zosankhidwa monga makhalidwe othamanga ndi mphamvu zopanda malire.

2. Pamene sing'anga yamadzimadzi ndi kuyimitsidwa komwe kumakhala ndi tinthu tambiri ta abrasive, zinthu zamkati za valve ziyenera kukhala zolimba.

3. Chifukwa chakuti sing'angayo ndi yowonongeka, yesani kusankha valve yokhala ndi dongosolo losavuta.

4. Pamene kutentha ndi kupanikizika kwa sing'anga kumakhala kwakukulu ndikusintha kwambiri, valavu yomwe zinthu zake zapakati pa valve ndi mpando wa valve sizimakhudzidwa kwambiri ndi kutentha ndi kupanikizika ziyenera kusankhidwa.

5. Kung'anima evaporation ndi cavitation zimachitika madzi TV. Pakupanga kwenikweni, kuphulika kwa evaporation ndi cavitation kumayambitsa kugwedezeka ndi phokoso, zomwe zidzafupikitsa moyo wautumiki wa valve. Choncho, kung'anima evaporation ndi cavitation ayenera kupewedwa posankha valavu.

Khalidwe

1. Pali mitundu yosiyanasiyana ya ma valve olamulira, ndipo nthawi zawo zogwirira ntchito ndizosiyana. Choncho, mtundu wa valve yolamulira uyenera kusankhidwa moyenera malinga ndi zofunikira za kupanga ndondomeko.

2. Ma valve oyendetsa mpweya amagawidwa m'magulu awiri: kutsegula mpweya ndi kutseka kwa mpweya. Valve yotsegulira mpweya imatsekedwa mu vuto lolakwika, ndipo valavu yotseketsa mpweya imatsegulidwa mu vuto lolakwika. Zida zina zothandizira zingagwiritsidwe ntchito kupanga valavu yosungira kapena kupanga valavu yolamulira yodzitsekera yokha, ndiko kuti, valavu yolamulira imasunga valavu yotsegula isanayambe kulephera ikalephera.

3. Njira yotsegulira mpweya ndi kutseka kwa mpweya imatha kuzindikirika ndi mitundu ya machitidwe abwino ndi oipa komanso kuphatikiza ma valve abwino ndi oipa. Mukamagwiritsa ntchito choyika valavu, imathanso kuzindikirika ndi choyika valavu.

4. Ma valve olamulira osiyanasiyana ali ndi mapangidwe ndi makhalidwe osiyanasiyana.
