Kodi valavu yoyezera madzi ndi iti yoyenera kugwiritsa ntchito?

Valavu yowunikira ndi chida chofunikira kwambiri chowongolera madzi, chomwe chimagwiritsidwa ntchito mosiyanasiyana, choyenera mitundu yosiyanasiyana yamadzimadzi. Izi ndi chidule chatsatanetsatane cha njira yowunikira madzi yomwe imagwira ntchito pa valavu yowunikira:

Choyamba, zinthu zodziwika bwino zamadzimadzi

1. Madzi osakaniza

Madzi: Ma valve oyezera amagwiritsidwa ntchito kwambiri m'machitidwe operekera madzi ndi otulutsira madzi kuti apewe zinyalala kapena madzi kubwerera m'mbuyo.

Mafuta: kuphatikizapo mafuta odzola, mafuta a hydraulic, ndi zina zotero, valavu yowunikira imatha kuletsa kubwerera kwa mafuta ndikuteteza zida kuti zisawonongeke.

Asidi Lye: Mu makampani opanga mankhwala, ma valve oyezera angagwiritsidwe ntchito kutulutsa zinthu zowononga za asidi ndi alkali.

Zakumwa zina: monga asidi, lye ndi zina zamadzimadzi zokhala ndi makhalidwe apadera, valavu yoyezera nayonso ndi yoyenera, koma ndikofunikira kusankha zinthu zoyenera ndi kapangidwe kake malinga ndi mawonekedwe a sing'anga.

2. Gasi wosakaniza

Mpweya: Valavu yowunikira imaletsa mpweya kubwerera m'mbuyo mu dongosolo lopondereza mpweya.

Nayitrogeni, mpweya ndi mpweya wina wa mafakitale: mu chitsulo, zitsulo, petrochemical ndi mafakitale ena, ma valve owunikira amagwiritsidwa ntchito kuti aletse mpweya wa mafakitale kubwerera m'mbuyo.

Gasi: monga gasi, gasi wachilengedwe, ndi zina zotero, valavu yoyang'anira imayikidwa kumapeto kwa payipi ya gasi kuti mpweya usabwerere m'mbuyo ndikuwonetsetsa kuti ogwiritsa ntchito ali otetezeka.

3. Sitima ya nthunzi

Kutentha kochepa, kutentha kwapakati, nthunzi yotentha kwambiri: Valavu yowunikira imagwira ntchito mu dongosolo la nthunzi kuti iteteze kubwerera kwa nthunzi ndi nyundo yamadzi, kuteteza zida kuti zisawonongeke.

Chachiwiri, njira yapadera yamadzimadzi

Madzi a zinyalala ndi zinyalala: Mu njira zotsukira zinyalala ndi zotulutsira madzi a zinyalala, ma valve oyezera amagwiritsidwa ntchito kuti aletse zinyalala ndi zinyalala kubwerera m'mbuyo komanso kuteteza chilengedwe ndi zipangizo.

Madzi a m'nyanja: Ma valve oyezera angagwiritsidwe ntchito m'makina otulutsira madzi a m'nyanja kuti apirire dzimbiri ndi kuwonongeka kwa madzi a m'nyanja.

Mafuta ndi mankhwala amphamvu pang'ono: Muzochitika zinazake zamafakitale, valavu yoyezera ingagwiritsidwe ntchito kutulutsa mafuta ndi mankhwala amphamvu pang'ono ndi zinthu zina.

Chachitatu, gawo la ntchito

Malo ogwiritsira ntchito ma valve owunikira amaphimba pafupifupi madera onse omwe ndikofunikira kuti apewe kubwerera kwa media, kuphatikiza koma osati kokha:

Moyo wa m'nyumba: monga madzi ndi ngalande, malo ophikira madzi, makina ochapira ndi ochapira ndi zipangizo zina zapakhomo.

Kupanga mafakitale: monga mankhwala, mafuta, zitsulo ndi mafakitale ena omwe ali mu dongosolo la mapaipi.

Makina a Hvac: monga mapaipi operekera madzi otentha ndi makina otenthetsera.

Dongosolo la mpweya: monga mpweya kapena mpweya wachilengedwe.

Magawo atsopano a mphamvu: monga makina amadzi otentha a dzuwa, makina amagetsi amphepo, ndi zina zotero.

Kuteteza chilengedwe: monga kukonza zinyalala, kutentha zinyalala ndi mapulojekiti ena oteteza chilengedwe.

Mwachidule, valavu yoyesera ndi yoyenera mitundu yosiyanasiyana ya zinthu zamadzimadzi, kuphatikizapo zinthu zamadzimadzi wamba, zinthu za gasi ndi nthunzi, komanso zinthu zapadera zamadzimadzi otayira, madzi otayira, madzi a m'nyanja, mafuta ndi mankhwala amphamvu apakatikati ndi zinthu zina. Posankha valavu yoyesera, zinthu zoyenera, kapangidwe kake ndi chitsanzo chake ziyenera kusankhidwa malinga ndi mawonekedwe a chinthucho, kuthamanga kwa ntchito, kutentha ndi zina.
