Handle Ball Valves Opanga

Mfundo yogwira ntchito ya valavu ya mpira ndikupangitsa kuti valavu isatsekeke kapena kutsekedwa pozungulira pakati pa valve. Chophimba cha valve ya mpira ndi chopepuka, chaching'ono kukula kwake, chimatha kupangidwa kukhala mainchesi akulu, kusindikiza kodalirika, kapangidwe kosavuta, kukonza kosavuta, kusindikiza pamwamba ndi malo ozungulira nthawi zambiri zimatsekedwa, ndipo sizing'ambika mosavuta ndi sing'anga, amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana.
Izo ntchito ngati izi:
njira yotseguka
1 Pamalo otsekedwa, mpira umakanikizidwa pampando wa valavu ndi makina amagetsi a tsinde la valve.
2 Pamene gudumu la m'manja litembenuzidwa mosiyana, tsinde la valavu limasunthira mbali ina, ndipo pansi pake pansi pa ngodya imapangitsa mpirawo kuchoka pampando wa valve.
3 Tsinde limapitilira kutukuka ndikulumikizana ndi pini yolondolera mu tsinde la tsinde, zomwe zimapangitsa kuti mpirawo uyambe kuzungulira popanda kugundana.
4 Mpaka itafika pamalo otseguka, tsinde la valavu limakwezedwa kumalo ocheperako, ndipo mpirawo umazungulira pamalo otseguka.
shutdown ndondomeko
1 Ikatsekedwa, tembenuzirani gudumu lamanja mozungulira, tsinde la valve limayamba kutsika ndipo mpirawo umachoka pampando wa valve ndikuyamba kuzungulira.
2 Pitirizani kutembenuza gudumu lamanja, tsinde la valavu limayendetsedwa ndi pini yowongolera yomwe imayikidwa pamwamba pa spiral groove, kotero kuti tsinde la valve ndi mpira zimazungulira 90 ° nthawi yomweyo.
3 Atangotsala pang’ono kutseka, mpirawo unazungulira 90° popanda kukhudzana ndi mpando.
4 Pamatembenuzidwe angapo omaliza a gudumu la m'manja, ndege yaing'ono yomwe ili pansi pa tsinde la valavu imamangirira mpirawo molimba mtima kumpando wa vavu kuti ukwaniritse chisindikizo chonse.
