Taupānga:
Ko te momo DZ nga momo pehanga pehanga he marere raupapa pehanga e whakahaerehia ana. Ka whakamahia mo te huringa raupapa e whakawhirinaki ana ki te pehanga o te ara iahiko tuarua.
Wāhanga me te tohu o te Pressure Sequence Valve DZ
Ko nga reera raupapa pehanga te tikanga o te takirere matua (1) me te whakauru porowhita matua (7) me te
takirere pairati (2) me te huānga whakatikatika pehanga me te taki taki (3), ka taea.
He rereke te mahi o te paera i runga i te whirihoranga wairere hinu pairati:
Momo takirere raupapa DZ. 50B/..
(Nga rarangi mana 4.1, 12 me 13 e tuwhera ana; rarangi mana 4.2, 14 me 15 kua monohia)
Ko te pehanga i te raina A ka mahi i runga i te spool pairati (5) i roto i te puera pairati (2) ma te raina whakahaere (4.1).
I te wa ano ka mahi ki te taha o te puna kua utaina o te porowhita matua (7) ma te kohao (6).
ka nui ake te pehanga i te uara kua whakaritea i te puna (8), ka nekehia te piston (5) ki te puna (8).
Ka whiwhi te tohu i roto i te tauranga A ma te raina mana (4.1).
Ko te wai kei te taha o te puna kua utaina o te piston matua (7) ka rere ki te tauranga B ma te kohao (9), te whenua whakahaere (10) me nga raina whakahaere (11) me te (12). (7), ka tuwhera te hononga mai i te tauranga A ki te tauranga B e mau tonu ana te pehanga i te puna (8). Ko te hinu rerenga i te piston pairati (5) ka arahina ki te tauranga B a roto ma te raina mana (13). Ka taea te whakauru i tetahi takitaki (3) hei utu kore utu mai i te tauranga B ki A.
Momo takirere raupapa DZ...50B/...X..
(Kua tuwhera nga rarangi mana 4.2, 12 me 13; rarangi mana 4.1, 14 me 15 kua honoa)
Ko te mahi o tenei takirere he tino rite mo te valve DZ--50B/.
Heoi, i runga i te raupapa pehanga momo takirere DZ...50B/...X... ka tukuna te tohu ki waho e
tikanga o te raina mana (4.2).
Sequence valve type DZ...50B/...Y.
(Nga rarangi mana4.1, 12 me 14, 15 ranei e tuwhera ana; rarangi mana 4.2, me te 13 kua monohia)
Ko te mahi o tenei valve he tino rite mo te momo valve DZ...50B/... Heoi, mo te momo DZ. .50B/...Y... te turuturu i te piston pairati (5) me whakaheke ki te tank me te kore pehanga ma te raina (14) ranei (15). Ka tukuna te hinu pairati ki te tauranga B ma te raina (12).
Momo takirere raupapa DZ...50B/...XY..
(Nga rarangi mana 4.2, 14, 15 ranei e tuwhera ana; rarangi mana 4.1, 12 me 13 kua monohia)
Ko te pehanga i roto i te tauranga X ka mahi i runga i te piston pairati(5) i roto i te puera pairati(2) ma te raina mana(4.2). I taua wa ano
Ko te pehanga o te wa i te tauranga A ka mahi ki te taha o te puna kua utaina ki te taha o te porowhita matua (7) ma te orifice (6). Ina
ko te pehanga o te tauranga X ka nui ake i te uara kua whakaritea i te puna (8), ka nekehia te piston (5) ki te puna (8). Ina nekehia te piston pairati (5) ki te puna (8), ka rere atu te wai mai i te taha o te puna kua utaina ki te taha o te spool matua (7) ki roto i te ruma puna (17) o te takirere pairati (2) ma te orifice (9)
me te raina (16) ka pakaru te pehanga ki te taha o te puna kua utaina o te porowhita matua (7).
Ka taea e te wai te rere mai i te tauranga A ki te B me te iti o te pehanga. Ko te hinu pairati i roto i te ruma puna (17) me whakaheke ki te tank me te kore pehanga ma te raina (14) ranei (15). Ka taea te whakauru i tetahi takitaki (3) hei utu kore utu mai i te tauranga B ki A.
