Nkawm ntawv
Qhov valve tso zog yog ib qho valve khoos tshwj xeeb uas muaj ib daim npoo hinged (lossis "gate") hauv nruab nrab. Daim flow: thaum cov duab ntsuab (ntsuab) hlwg mus rau hauv qhov valve inlet, qhov siab yuav dhau los npoo npoo, pab tau rau kev flow.
Kev tshem tshem rov qab: thaum cov duab ntsuab txiav mus rov qab, lossis thaum lub veej phom thiab pitch, ua rau lub teb chaws ntsuab hloov, cov ntsuab rov qab yuav dhau los npoo rov qab rau hauv qhov chaw. Qhov siab ntawm cov duab ntsuab thiab qhov loj ntawm daim npoo yuav tshem ceev qhov valve, tiv thaiv kev rov qab tas li.
Cov Ntu Zoo Thaum Kev Siv Thiab Qhov Chaw Txwv
Kev Tshawb Xam Ib Qhov Muaj Zog: Tsuas xoom tsis tas kawm los ntawm chav kawm, tshwm sim los ntawm lub hmoob thiab qhov chaw tshwj xeej kom muaj kev sib txawv ib leeg. Kev Tswj Hwm Koj Khaum Kawg: Ib qhov tseem ceeb tshaj plaws, tias nyob rau hauv qhov chaw nyob ntawm lub tshuab ntxoov ntxoo, chav ntxoov ntxoo, chav sov hlau, thiab lwm yam, kom nyob deb ntawm kev nyob siab nyob rau hauv av. Kev Txhim Kev Siv Hluv: Lub raj muaj kev ua haujlwm zoo, tsim kev pheej hmong siab tshaj tawm rau kev sib thooj. Nyiaj Nyim Kev Sau Npe: Lub raj tsho yog feem ntau tuaj yeem tshuam tau, kom pom zoo thiab kho cov khoom nyob hauv (xws li lub raj thiab seals). Kev Tsoom Siab Zoo: Lub raj tsho muaj qhov chaw tsoom siab feem ntau tsim los ntawm duv (xws li nitrile rubber NBR, EPDM) lossis tshiab + duv kom tsoom siab khiav khiav.
