Valavu yowongolera imakhala ndi thupi la valavu, zida zamkati za valve, chowongolera chomwe chimapereka ma valavu oyendetsa, ndi zida zosiyanasiyana. Zida zama valve zimaphatikizapo ma poyizoni, ma transducers, zowongolera zamagetsi, ma valve solenoid, ma dampers ndi masiwichi ochepera.

1. Kusankha ndi kugwiritsa ntchito ma valve olamulira
Kusankhidwa kolondola kwa mavavu owongolera komanso ngati kukwaniritsa zofunikira zoyendetsera ntchito za kiyi, komanso kuonetsetsa chitetezo cha njira. Kuti akwaniritse zofunikira zomwe zafotokozedwa, kusankha ma valve owongolera kuyenera kuganizira mtundu wa ma valve, mawonekedwe ndi zida za ma valve, mtundu wa actuator ndi chitetezo ndi zinthu zina. mtundu wosankhidwa wa valve wosankhidwa ndi wosakaniza bwino.

2. Zosankha zowongolera ma valve ziyenera kuganiziridwa
Kuti musankhe valavu yolamulira yoyenera pazochitikazo, muyenera kuganizira mozama momwe valavu yoyendetsera ntchito imakhudzira mitundu yosiyanasiyana ya ntchito. Chidziwitso chofunikira kwambiri kuphatikiza kuwongolera kwa mtundu wamadzimadzi, kutentha kwamadzi, kukhuthala kwamadzimadzi, mphamvu yokoka yamadzimadzi, mphamvu yayikulu komanso yocheperako, kuthamanga kwambiri komanso kocheperako kwa cholowera cha valve, kuthamanga kwambiri komanso kutsika kwa valve, kupanikizika. kutsika pansi pazikhalidwe zoyenda bwino, kuchuluka kwa anthu ndi chitoliro chotuluka ndi makulidwe a khoma.

3. Njira yosankha ma valve
Momwe mungasankhire valavu yoyendetsera bwino kuti mukwaniritse zofunikira zomwe zikugwiritsidwa ntchito, ndondomeko yosankha ma valve osachepera ayenera kuganizira zotsatirazi. Dziwani zikhalidwe za ntchito: kuphatikiza kuchuluka kwa ma valve ndi kutulutsa kwamphamvu kwambiri yosiyanitsira, pazipita, zochepa komanso zachilendo zogwirira ntchito pamlingo wothamanga, kutentha kwamadzi ndi phokoso lovomerezeka. Werengani C-mtengo wofunikira, ndikuwona kuchuluka kwa phokoso, cavitation ndi kung'anima powerengera ℃-value). Kusankhidwa kwa mtundu wa valve mkati mwa valve: Ngati mtengo wowerengeka wa phokoso ndi waukulu kuposa malire omwe amaloledwa ndi malo ogwirira ntchito, ndiye kuti kusankha kwa ma valve ochepetsera phokoso kuyenera kuganiziridwa. Ngati cavitation yowerengeka kapena kung'anima kwa valavu mu ntchito yotchulidwa pansi pa kugwiritsidwa ntchito kwa nthawi yaitali kwa chiwopsezo chachikulu, chiyenera kuganiziridwa pazikhalidwe zodziwika za anti-cavitation ndi anti-flash valve components.
