Chifukwa chiyani valavu siyikutsekedwa mwamphamvu? Kodi kuthana nazo?

Valavu nthawi zambiri imakhala ndi mavuto ovuta panthawi yogwiritsira ntchito, monga valavu sitsekedwa mwamphamvu kapena mwamphamvu. Kodi nditani?

Muzochitika zachilendo, ngati sichitsekedwa mwamphamvu, choyamba tsimikizirani ngati valve yatsekedwa. Ngati yatsekedwa m'malo mwake, palinso kutayikira ndipo sikungathe kusindikizidwa, fufuzani malo osindikizira. Mavavu ena ali ndi zisindikizo zomwe zimatha kuchotsedwa, choncho zitulutseni ndikuzipera ndikuyesanso. Ngati sichinatsekedwe mwamphamvu, chiyenera kubwezeretsedwa ku fakitale kuti ikonzedwe kapena kusinthidwa kwa valve, kuti zisakhudze kugwiritsa ntchito bwino kwa valve ndi zochitika za mavuto monga ngozi za ntchito.

Ngati valavu sitsekedwa mwamphamvu, choyamba muyenera kudziwa komwe kuli vuto, ndiyeno kulithetsa molingana ndi njira yoyenera.

Zifukwa zomwe ma valve samatsekedwa mwamphamvu nthawi zambiri ndi izi:

(1) Pali zonyansa zomwe zimakakamira pamtunda wosindikiza, ndipo zonyansa zimayikidwa pansi pa valve kapena pakati pa valve clack ndi mpando wa valve;

(2) Ulusi wa tsinde la valve ndi wa dzimbiri ndipo valavu silingatembenuzidwe;

(3) Kusindikiza pamwamba pa valavu kumawonongeka, kuchititsa kuti sing'anga iwonongeke;

(4) Tsinde la valavu ndi valavu ya valve sizikulumikizidwa bwino, kotero kuti phokoso la valve ndi mpando wa valve sizingagwirizane.

Njira yochizira valavu sitsekedwa mwamphamvu:

1. Zonyansa zomwe zimamatira pamalo osindikizira ma valve

Nthawi zina valavu sitsekedwa mwamphamvu mwadzidzidzi. Zitha kukhala kuti pali chodetsedwa chomwe chakhazikika pakati pa malo osindikizira a valve. Panthawiyi, musagwiritse ntchito mphamvu kuti mutseke valve. Muyenera kutsegula valavu pang'ono, ndiyeno yesani kutseka. Yesani mobwerezabwereza. Nthawi zambiri, imatha kuthetsedwa. Onaninso. Ubwino wa zoulutsira nkhani uyeneranso kukhala waukhondo.

Chachiwiri, ulusi wa tsinde ndi dzimbiri

Kwa ma valve omwe nthawi zambiri amakhala otseguka, akatsekedwa mwangozi, chifukwa ulusi wa tsinde wa valavu wachita dzimbiri, sangatseke mwamphamvu. Pankhaniyi, valavu ikhoza kutsegulidwa ndi kutsekedwa kangapo, ndipo pansi pa thupi la valve ikhoza kugwedezeka ndi nyundo yaing'ono panthawi imodzimodzi, ndipo valavu ikhoza kutsekedwa mwamphamvu popanda kugaya ndi kukonza valavu.

Chachitatu, valavu yosindikiza pamwamba yawonongeka

Ngati kusinthaku sikunatsekedwe mwamphamvu pambuyo poyesera kangapo, ndiko kuti, malo osindikizira awonongeka, kapena malo osindikizira awonongeka ndi dzimbiri kapena tinthu tating'onoting'ono pakatikati. Pankhaniyi, iyenera kufotokozedwa kuti ikonzedwe.

Chachinayi, tsinde la valve ndi clack ya valve sizikugwirizana bwino

Pankhaniyi, m'pofunika kuwonjezera mafuta odzola ku tsinde la valve ndi mtedza wa tsinde la valve kuti muwonetsetse kutsegula ndi kutseka kwa valve. Payenera kukhala dongosolo lokonzekera lokonzekera kulimbikitsa kukonza kwa valve.
