200X te pehanga whakaheke wai
Ko te 200X te whakaheke pehanga, ka kiia ranei ko te waahi whakapumau (te whakaheke i te pehanga whakaheke whakaheke) kei roto ko te maapiri matua, he paera pairati, he paera ngira, he paera poro,
he tātari moroiti me te ine pehanga hei hanga i te punaha hononga mana waipēhi. I te wa e whakamahia ana, i muri i te tautuhi i te pehanga putanga, ka taea e te valve te pupuri aunoa i te pehanga putanga.

Mahi
Ko te paera whakaheke pehanga he paera e whakaheke ana i te pehanga urunga ki tetahi pehanga putanga e hiahiatia ana ma te whakatikatika, me te whakawhirinaki ki te kaha o te reo ake
kia mau tonu te pehanga putanga. Mai i te tirohanga o nga miihini wai, ko te riipene whakaheke pehanga he huānga whakaheke ka taea te whakarereke i te aukati o te rohe,
ara, ma te huri i te waahi tarai, te tere o te rere me te kaha kinetic o te wai, ka puta mai he rereke o te pehanga mate, kia tutuki ai te kaupapa o te whakaheke.
Na ka whakawhirinaki ki te whakarereketanga o te mana whakahaere me te punaha whakahaere ki te whakataurite i te rereketanga o te pehanga o muri o te paera me te kaha o te puna, kia pai ai te pehanga o muri.
ka noho tonu i roto i te awhe kawa.
Hua Whakaatu
1. Kuti o te pehanga wai whakaheke i te vlave
2. Diaphgram and Spring of the control valve
3. Bonnet, Insider me waho FEB paninga Min. 300Mironi.
4. Ka huihui te pehanga awhina awhina
5. Maangi mana rere
6. Pressure Whakaiti takirere huihui
Ko te paera whakaheke pehanga he paera e whakaiti ana i te pehanga urunga ki tetahi pehanga putanga e hiahiatia ana ma te whakatikatika, me te whakawhirinaki ki te kaha o te reo kia mau tonu te pehanga o te putanga. Mai i te tirohanga o nga miihini wai, ko te puera whakaheke te pehanga he huānga whakaheke ka taea te whakarereke i te parenga o te rohe, ara, ma te whakarereke i te waahi kaitao, te tere o te rere me te kaha kinetic o te wai, ka puta mai he rereke o te pehanga. kia tutuki ai te kaupapa o te whakaheke. Na ka whakawhirinaki ki te whakarereketanga o te mana whakahaere me te punaha whakahaere ki te whakataurite i te rereketanga o te pehanga o te pou-valve me te kaha o te puna, kia mau tonu te pehanga o muri i roto i te awhe manawanui.
Ko te rere o te wai i roto i te paera whakaheke pehanga he nui te mahunga o te mahunga, engari he kaha tonu te whakaora i te kaha i te nuinga o te waa na te mea ka whakaitihia te ururua o te wai, ka pai te tohatoha o te punaha, me te whakapai ake i te whakatakotoranga o te punaha me nga tikanga mahi. Mo te pai o te mahi, te whakatikatika me te tiaki, me whakauru te puera whakaheke pehanga ki runga i te pipeline whakapae
