Onani mfundo zogwirira ntchito, gulu ndi kusinthasintha

Valavu imagwira ntchito

AChongani valavu imagwiritsidwa ntchito mu bomba la mapaipi, ndipo ntchito yake yayikulu ndikuletsa kubwezeretsa kwa sing'anga, kusintha kwa pampu ndi kuyendetsa galimoto yake, komanso kutulutsa kwa sing'anga.

Chongani Mavalve Itha kugwiritsidwanso ntchito pamiyala yomwe imathandizira kuti kupanikizika kwanu kungakhale pamwamba pa dongosolo lalikulu dongosolo. Chongani mavesi amatha kugwiritsidwa ntchito pa mapaipi osiyanasiyana malinga ndi zida zosiyanasiyana.

Vesi la cheke limayikidwa payipi ndikukhala imodzi mwamadzi am'madzi onse. Njira zotseguka ndi zotsekera za valavu imakhudzidwa ndi mawonekedwe otsika a dongosolo momwe liliri; Nawonso, mikhalidwe yotsekera ya valavu ya Valve ndi yokhudza mpweya wa madzi.

Chongani gulu la valavu

1. Swing Check valavu

Chingwe cha cheke chowoneka bwino chimakhala cha disc ndipo chimazungulira mozungulira shaft ya ma valve pannel. Chifukwa choti njira yomwe ili pachigwa chafupika, kukana koyenda kumakhala kocheperako kuposa momwe nkhungu yokweza. Ndioyenera mitengo yotsika yotsika komanso kusintha kwakanthawi kochepa. Komabe, sioyenera kutulutsa kuyenda, ndipo chipilala chake chisindikizo sichabwino ngati cha mtundu wokweza.

Vesive Check Vatve amagawidwa m'mitundu itatu: Mtundu wa Lobe-Lobe, mtundu wa Lobe-Lobe-Lobe-Lobe-Lobe. Mitundu itatu iyi imagawika molingana ndi ma valana.

2. Fufuzani valavu

Valani valavu yomwe ya Valani ya Valve imadutsa pakati pa thupi la valavu. Valavu yokweza imatha kukhazikitsidwa pa mapaipi opingasa, ndipo mpira ukhoza kugwiritsidwa ntchito pa valavu yochepa kwambiri. Mphamvu yamphamvu ya Valani ya valavu yokweza ndiyofanana ndi valavu yapadziko lapansi (iyo itha kugwiritsidwa ntchito pofala ndi valavu ya dziko lapansi), kotero madzi ogwirizana ndi madziwo ndi akulu. Kapangidwe kake kamafanana ndi valavu yapadziko lapansi, ndipo thupi la valavu ndi disc ndi ofanana ndi Valve wapadziko lapansi.

3. Gulugufe

Valani valavu yomwe disc imazungulira pini pampando. Vesi ya disc Check ili ndi mawonekedwe osavuta ndipo imangoikidwa pa mapaipilo opingasa, ndipo magwiridwe ake osauka ndi osauka.

4..

Valani yomwe kambuku imatsika pakati pa thupi la valavu. Mapaipi a Pipe Lake ndi valavu yatsopano. Ndi yaying'ono kukula, kuwala kolemera komanso zabwino pakukonza ukadaulo. Ndi imodzi mwamayendedwe a chitukuko cha cheke valavu. Komabe, kulumikizana kogwirizana ndi kokulirapo ndi kwakukulu pang'ono kuposa momwe zimakhalira ndi valavu.

5. Kupanga Chete Valve

Valavu iyi imagwiritsidwa ntchito ngati boiler kudyetsa madzi ndi valavu yodula, imakhala ndi ntchito yophatikizira kukweza valavu yokweza ndi khungu la dziko lapansi.

Kuphatikiza apo, pali mavavu ena omwe sayenera kukhazikitsa kapulogalamu yotulutsa, monga valavu yama phazi, mtundu wa masika, y mtundu, etc.
