Kodi pali kusiyana kotani pakati pa valavu yokhala chete komanso valavu yokhazikika?

M’malo mwa mphamvu zamadzimadzi, mavesi amatenga mbali yofunika kwambiri yowongolera kutuluka kwa zakumwa ndi mpweya mkati mwa dongosolo. Mwa mitundu yosiyanasiyana ya mavunda, zosankha ziwiri zomwe zakambidwa ndi Valve yokhala chete komanso valavu yokhazikika. Pomwe onse akusunga kuti aletse kubwezeretsa m’mapaipoli, pali kusiyana kosiyana komwe kumapangitsa kuti valaile iliyonse ikhale yoyenera kugwiritsa ntchito njira zosiyanasiyana.

Kodi valavu ya cheke ndi chiyani? 

Tisanachenjetse kusiyanasiyana, tiyeni tifotokozere zomwe valavu ndi. Valani valavu ndi chipangizo chopangira chopangidwa kuti chithandizire kuti madzi akuyenda mbali imodzi yokha. Izi ndizofunikira kuteteza zida, kukhalabe ndi zipani, ndikuonetsetsa chitetezo m’machitidwe osiyanasiyana, kuphatikizapo kupendekera, kutentha, kugwiritsa ntchito mafakitale.

Chowunikirana pafupipafupi: mwachidule

Valavu yokhazikika imagwira ntchito pogwiritsa ntchito njira yosavuta – disc kapena mpira womwe umasunthira momasuka mkati mwa thupi. Kuyenda kwamadzi kumakhala koyenera, disc imakwezedwa, kulola madzi kudutsa. Komabe, ngati pali mayendedwe osiyanasiyana, disc kapena mpira watulutsidwa motsutsana ndi mpando, kuyika bwino valavu komanso kupewa.

Chifukwa cha kapangidwe kawo koyambira, mavu amadzi okhazikika amatha kutulutsa "nyundo yamadzi yodziwika bwino" Izi zitha kukhala zovuta m’magawo omwe magawo a phokoso amafunikira kuti azikhala ochepa, monga mu malo okhala ogona kapena okonda mafakitale.

Valati Check Valve: yankho lapadera 

Mosiyana ndi izi, a valavu yachete Muli ndi kapangidwe kake kovuta kwambiri poyerekeza phokoso logwedezeka komanso hydraulic mantha okhudzana ndikutseka. Nthawi zambiri imakhala ndi makina onyamula masika omwe amalola kuti azichita bwino. Kutuluka kumayima kapena kusinthika, kasupe umatsekera bwino valavu, kuchepetsa kapena kuthetsa zotsatira zamadzi.

Valavu yokhala chete ndiofunika kwambiri pakugwiritsa ntchito komwe kutsika kwa phokoso ndi nkhawa yovuta. Kuphatikiza pa kuletsa kubwezeretsa ngati mnzake wanthawi zonse, valavu yamitundu iyi imakonda kutengera njira zotetezera moto, mayunitsi a HVac, ndi masinthidwe ena omwe amayang’ana ntchito.

Kusiyana kwakukulu

1. Chenjezo:
Kusiyana kwakukulu pakati pa valavu yokhala chete komanso valavu yokhazikika ndi phokoso. Monga tanena, mavuvu osakachetechete amachepetsa mawu, kuwapangitsa kukhala abwino kuti azikhala okoma, pomwe ma valve okhazikika amatha kusokoneza phokoso potseka.

2.:
Mavesi okhazikika amagwiritsa ntchito mawonekedwe owongoka omwe amadalira mphamvu yokoka kapena kuyenda kuti atseke. Mosiyana ndi izi, mavuvu ache chete amaphatikizira zigawo zodzaza ndi masika, kulola kutseka kowonjezereka ndikuchepetsa mafunde m’dongosolo.

3. Ntchito:
Popeza mawonekedwe awo, mavuvu osakhala chete nthawi zambiri amagwiritsidwa ntchito pogwiritsa ntchito komwe ntchito yabata ndiyofunikira. Mavesi okhazikika amatha kukhala okwanira madera osakwanira kapena pomwe pali mtengo wofunikira pakusankha valavu.

Mukamaganizira mtundu wanji wa cheke van kuti mugwiritse ntchito pogwiritsa ntchito, ndikofunikira kuti mudziwe zabwino ndi kuchuluka kwa aliyense. Valavu yokhala chete imapereka njira yapamwamba yomwe imachepetsa phokoso komanso hydraulic strict, pomwe valavu yokhazikika ikhoza kukhala yoyenera kugwiritsidwa ntchito molunjika. Kumvetsetsa izi kumatha kuthandiza akatswiri ndi opanga madongosolo a makina adziwitse zisankho kuti atsimikizire kuti amayendetsa bwino ntchito ndi dongosolo lokhalamo.

Pomaliza, pomwe mavuvu onse opanda phokoso ndi zinthu zofunika kwambiri pazinthu zokhazikika m’magulu ammadzi, kusankha pakati pa awiriwo kudziwitsidwa ndi zosowa zenizeni za pulogalamuyi, makamaka pankhani ya maphokoso ndi luso logwira ntchito.
