Ntchito yayikulu ya valavu yotulutsira madzi m'makina otenthetsera ndikutulutsa madzi a zinyalala kuchokera mumakina otenthetsera kuchokera kumapeto ambiri, kugwiritsa ntchito kwake ndi kofanana ndi valavu ya mpira.

Mankhwalawa ayenera kugwiritsidwa ntchito pansi pa mikhalidwe iyi:

1. Kupanikizika kwa ntchito: ≤1.0 MPa (Dziwani: Kupanikizika kogwira ntchito komwe makasitomala amafunikira kungakhale kosiyana ndi kwa mavavu. Pogwiritsa ntchito kuthamanga kogwira ntchito, sikuyenera kupitirira kuthamanga kogwira ntchito komwe kwasindikizidwa ndi thupi la valavu ndi

chogwirira cha zinthu za kampani yathu).

2. Zogwiritsira ntchito: madzi ozizira ndi otentha.

3. Kutentha kogwira ntchito: 0-100℃. Pa kutentha kochepa, sing'anga iyenera kukhala yamadzimadzi kapena ya gasi, ndipo sipadzakhala ayezi kapena tinthu tating'onoting'ono tolimba mu sing'anga.

Kukhazikitsa ndikofunikira:

1. Chonde sankhani valavu malinga ndi momwe ntchito ikuyendera. Ngati valavu ikugwiritsidwa ntchito kupitirira zomwe zafotokozedwa muukadaulo, idzawonongeka kapena kuphulika. Kapena, ngakhale valavuyo ingagwiritsidwebe ntchito mwachizolowezi, nthawi yogwira ntchito ya valavuyo idzafupikitsidwa.
2. Sankhani chida choyenera (wrench) malinga ndi kukula kwa valavu panthawi yoyika, ndipo konzani kumapeto kwa ulusi wopangira kuti mupewe kupsinjika kwa thupi la valavu. Mphamvu yoyika kwambiri ingayambitse kuwonongeka kwa valavu.
3. Magawo olumikizirana kapena ma bend okulitsa ayenera kuyikidwa pamapaipi ataliatali kuti athetse kupsinjika komwe kumayikidwa pama valve chifukwa cha kutentha ndi kupindika kwa mapaipi.
4. Malekezero akutsogolo ndi kumbuyo kwa mavavu ayenera kukhazikika kuti valavu isawonongeke chifukwa cha kupindika chifukwa cha kulemera kwa mapaipi ndi zolumikizira.
5. Ma valve ayenera kukhala otseguka mokwanira panthawi yoyika. Pamene payipi yatsukidwa ndi kuyikidwa, ma valve amatha kulowa momwe ntchito ikuyendera.

Zinthu zofunika kuziganizira pakugwiritsa ntchito:
1. Nthawi yotsegulira ndi kutseka ma valve a mpira osasinthidwa kwa nthawi yayitali imakhala yayikulu kuposa nthawi yanthawi zonse akatsegulidwa ndi kutsekedwa koyamba. Pambuyo pa switch imodzi, nthawi yotsegulira ndi kutseka imalowa mu mkhalidwe wabwinobwino.
2. Mukapeza kutuluka kwa madzi mu dzenje lapakati la valavu ya mpira, chivundikiro cha kupanikizika pa dzenje lapakati la valavu ya mpira chikhoza kumangirizidwa bwino motsatira wotchi ndi wrench yotseguka kuti zisatuluke. Kuzungulira kwambiri kudzawonjezera nthawi yotsegulira ndi kutseka.
3. Pansi pa momwe ntchito ikuyendera, valavu ya mpira imatsegulidwa kapena kutsekedwa momwe zingathere, zomwe zimathandiza kutalikitsa moyo wa valavu ya mpira.
4. Ngati cholumikizira mkati mwa valavu chazizira, chikhoza kusungunuka pang'onopang'ono ndi madzi otentha. Sikololedwa kupopera moto kapena nthunzi.
