fundo pakati pa .4/2 na 5/2 pneumatic mavalvuutesi mukati mwa madowoko ghakupambanapambana na nthowa izo ŵakugwiriskira ncito mphepo mu chipangizo ca pneumatic. apa pali kugaŵika kwa mphambano:
1. unandi wa Ports:
4/2 Valve:
Lili na madowoko ghanayi na maudindo ghaŵiri.
Kanandi madowoko ghakugaŵika nga ni:
P (pressure): wakukolerana na mphepo yakufinyikizgika.
A na B: kuseŵezeska madowoko, ghakukhwaskana na actuators (mwachiyelezgero, masilinda).
Exhaust: Poriti ya Vent yakutozga mphepo.
Waft yikulongozgeka ku na kufuma ku actuator (panji chida chakulaŵilirika), ndipo vavu yikulaŵilira nthowa ya mphepo ku actuator.
5/2 Valve:
Lili na madowoko 5 na maudindo ghaŵiri.
Kanandi madoko ghakugaŵika:
P (stress): kulumikizana na mphepo yakufinyikizgika.
A na B: kuseŵezeska madowoko, ghakukolerana na actuators (mwachiyelezgero, masilinda).
Mapoti gha Exhaust: kanandi madoko 2 ghakufumiskiramo (kanandi ghakugaŵika nga ni EA na EB) kuti ghafumye mphepo yakufumiskiramo apo valve yikusintha.
2. ntchito:
4/2 Valve:
chomenechomene pa mapulogalamu ghambura kusuzga apo actuator yimoza (nga ni silinda) yikulaŵilirika mu vigaŵa (kukuzga / retract).
maudindo ghaŵiri ghose ghazamuŵa:
kulumikizga P doko la P ku doko (irir mu actuator).
kulumikizga P doko la P ku doko la B (ilo likunjira mu chigaŵa chinyake cha actuator).
Exhaust: Pali chomene doko limoza lakufumiska mphepo iyo yikufumiska mphepo ku malo ghakuzingilizga apo mphepo yikusinthika panji kufuma mu actuator.
5/2 Valve:
versatile chomene kuluska vavu ya 4/2, chifukwa yikugwiriskirika nchito chomene mu mapaketi agho ghakukhumbikwira madowoko ghaŵiri ghakufumiskika (kupaturako kanandi ghakugwiriskirika nchito na kaŵiri - performing silindas).
Valve ya 5/2 yikulongozga mphepo ya mphepo ku doko panji doko B apo yikuperekaso madoko ghakupambanapambana ghakufumiska mphepo pa nthowa yiliyose.
Madoko ghakufumiramo: Madoko ghakufumiskika (pafupifupi EA na EB) ghakugwiriskirika nchito, ghakuzomerezga kufumiska mphepo kufuma ku vigaŵa vyose vya actuator.
3. Gwiliskirani nchito viyezgelero:
4/2 Valve:
kanandi ŵakugwiliskira ntchito pa ntchito zipusu izo palije chifukwa chakuti paŵe madoko ghakupambanapambana ghakufumiska mphepo.
kukondweska kwa kulaŵilira - silinda panji vinthu ivyo vikukhumbikwa mu nthowa yiwemi yimoza yakufumiramo.
5/2 Valve:
kanandi ŵakugwiliskira nchito kuti ŵapusike kaŵiri- ma silinda ghakugwira ntchito, apo madoko ghakukhumba nthowa yiliyose ya kusunkhunyika (chimoza pa chigaŵa chilichose cha piston).
kugwiriskira ncito mu ndondomeko zakusuzga comene apo kulaŵilira kwa mphepo nkhwakuzirwa comene pa kulaŵilira umo mphepo yikucitikira na umo mphepo yikuŵira.
vinayi. Kulaŵilira kwakukhozga soni:
4/2 Valve: kanandi ili na doko la 1 yakufumiramo.
5/2 Valve: Kasi 2 madowoko ghakufumiskika, agho ghakupereka mazaza ghanandi pa glide ya kufumiska ndipo ghakugwira ntchito mu mapaketi agho ghakukhumbikwira kuti ghalongozgeke makora panji kuŵika kaŵiri -} silinda yakuwonekera.
5. malo ghakupambanapambana:
| Chigawa | 4/2 Valve | 5/2 Valve |
|---|---|---|
| vingwe | 4 Vinthu | 5 Vinthu |
| Malo | 2 Malo | 2 Malo |
| Ports yakuzizika | chakukopa cha Podi doko doko doko doko doko lakuzizika . | 2 Chidindo |
| nawa | Kuchita vinthu mwambura kusuzga (single-acting) | Vinthu vyakusuzga chomene, vyakuŵika paŵiri, kuŵika paŵiri ma silinda |
| Nthowa | Kulaŵilira nthowa yayi | Kugula kwa kaŵiri {{0}pafupi na silinda, kulaŵilira kwakusuzga kwa msewu . |
Ntheura, .5/2 mavayinikanandi ŵakupambana chomene, ŵakupereka kulongozga kwapadera na kusinthasintha chomene pakulaŵilira kaŵiri - silinda yakuchita, apo .4/2 mavayinini vipusu ndiposo vyakwenelera pa mapulogalamu ghakusuzga ghambura kusuzga.
