Piston Rere Regulating Valves
Ngā āhuatanga
▪ Whakaritenga raina: ko te whakatuwheratanga me te rere o te valve he raina, ka taea te mohio ki te ture tika.
▪ He iti te utu tiaki me te roa o te mahi: te hongere rere tika me te kowhiringa rauemi e tika ana hei whakarite kia roa te ora o te puera.
▪ He iti te mana taraiwa: hoahoa taurite waipēhi, i honoa ki te takai arataki i runga i te koranu parahi kia pai ake te rere o te piston me te pono.
▪ Ko te whakaurunga whiriwhiri: ka taea te whakauru poutū, whakapae me te whakairi, ki tetahi taha ranei o te paipa.
▪ Te hiri ti'aturi (momo noa): te hanganga hoahoa motuhake o te houra elastomer;Ko te tuuru takirere whakarewa e hono ana me te hiera hiraka rapa nui e whakarato ana i te mana hiri taumata mirumiru, ka aukati i te tuuru takirere mai i te rakuraku me te whakaroa i te oranga o te tuuru takirere.
▪ Toreretanga pūngao tukinga me te wiri anti (momo orifice maha).
▪ Hoahoa poka koonika, whakangao ana (te momo orifice maha).
▪ Ka whakamahia mo te maha o nga kaupapa ka taea te whakakapi i te hiko hiko hiko me te momo Y-momo.
▪ Aratau mahi: te mahi ira waipēhi, te whakahaere hiko, te mahi taputapu kutukutu a-ringa me te whakahaere ruma whakahaere mamao.
▪ Te whakamahi i nga mahi: te whakahaere rere, te whakaheke i te pehanga, te pupuri i te pehanga, te whakahaere ture, te pupuri me te whakaheke i te pehanga.

Hanganga
Kaupapa Mahi
▪ Ko te nuinga o te waro whakahaere piston ko te tinana takirere, te nohoanga takirere, te piston, te pou takirere, te crank, te rakau hono, te titi taraiwa, te titi pana, te kawe me te tikanga whakahaere.
▪ Ka huri te piston regulating valve ki te neke axial o te piston i te taha o te rail arataki na roto i te miihini hono.I roto i te tukanga o te piston neke whakamuri, me te puta, te ture rere me te mana pēhanga e ite i te huri i te rohe rere i waenganui i te piston me te nohoanga takirere.
▪ Ka rere te wai ki roto i te tinana takirere mai i te axial arc.Ko te hongere rere i roto i te piston control valve he axisymmetric, karekau he ngangau ina rere te wai.
▪ Ahakoa te wahi e neke ana te piston, he annular te wahanga rere wai i roto i te ruma takirere i tetahi waahi, ka heke ki te tuaka i te putanga, kia pai ai te pai o te anti cavitation me te karo i te kino o te tinana takirere me te pipeline na te cavitation na te throttling.
