A 5/2 a directional control valve .tih hi pneumatic valve chi khat a ni a, chu chuan pneumatic gadget chhunga boruak kal dan tur a control a, a bik takin double-performing cylinders actuating atan a hmang a ni. "Five" tih hian port (connections) zat a kawk leh a, "2" hian position awm zat a kawk leh a (states valve chu a awm thei) a ni. A hnathawh dan chu hetiang hi a ni:
Five/2 valve-a thil pawimawh ber berte:
Port 5 a awm a:
P (stress): Air supply nena inzawm port.
A: port chu cylinder (or actuator) 1 facet nen a inzawm a.
B: port chu cylinder (or actuator) lam hawi zawngin a inzawm a.
EA (Exhaust A): Valve chu kawngpui pakhata a inthlak laiin actuator atanga chhuak air tan exhaust port a ni.
EB (Exhaust B): valve chu a kalh zawnga course a inthlak laiin actuator atanga chhuak air tan exhaust port a ni.
Hmun 2 awmna hmun:
Valve hian position pahnih a nei a, chu chuan float path a thlak danglam a, actuator chhunga boruak lut leh chhuah dan a control a ni.
A hnathawh dan:
Position 1 (relaxation function / de-enkawlna tichak):
Valve chu energized a nih loh chuan (a nih loh leh a "rest" function-ah) ports te chu hetiang hian configure a ni:
Port P (Air Deliver) chu Port A (cylinder aspect pakhat) nen a inzawm a.
Port B (cylinder sir lehlamah) chu exhaust port EA-ah an inzawm a, chu chuan boruak chu machine atanga chhuak turin a phalsak a ni.
Port EB chu khar a ni a, Port b.
He configuration hian cylinder chhunga piston chu 1 aspect ah a nawr a (eg, piston chu extend).
Position 2 (a dinhmun / chakna pek):
Valve chu energized a nih laiin (entir nan, solenoid a activate chuan) a internal mechanism chuan valve chu a pahnihnaah a shift a, float paths te chu a thlak danglam a:
Tunah chuan port P (air supply) chu port B nen a inzawm a, cylinder sir lehlamah boruak a thawn chhuak ta a ni.
Tunah chuan port A chu exhaust port EB nen a inzawm tawh a, hei hian boruak chu cylinder alternative facet atanga exhaust a phalsak a ni.
Port EA chu khar a ni.
He action hian piston chu a kalh zawngin a kal tir a (eg, piston retracting).
Glide manage 5/2 valve ah hian a awm a:
5/2 valve awm chhan chu double-acting cylinder lam hawi zawnga boruak kal dan nen GO kalpui dan tur a ni:
Role 1-ah chuan boruak chu cylinder lam hawi pakhatah a hruai lut a (allow’s say port A), alternative side-a boruak (port B) chu a tawp tawh a ni.
Position 2-ah chuan boruak kal dan tur kawng chu a inher leh a: boruak chu cylinder (Thru port B)-a thil danglam zawkah a hruai lut a, cylinder sir lehlama boruak chu EB hmangin a tawp tawh bawk.
Hman dan tlangpui: 1.1.
Double-Appearing Cylinders: 5/2 valve hi a tlangpuiin double-performing cylinder nen hman a ni a, chutah chuan piston chuan piston sir lehlamah air stress inthlak danglamin hma leh hnung lam (enlarge leh retract) a duh a ni.
Automation Structures: Robotics, conveyor, leh packaging machine ang chi automatic structure-ah valve panga/2 a awm a, chutah chuan enkawl a ngai a, repetitive motion a ngai a ni.
5/2 valve pakhat tan actuation style hrang hrang:
Manual: Guide lever, button emaw transfer emaw hmangin activate a ni.
Solenoid-Operated: Solenoid coil hmanga activate, chu chu a tlangpuiin electric hmanga enkawl a ni.
Pneumatic: Pneumatic sign dang hmangin a thawk a (a tlangpuiin pilot-managed emaw pilot-operated tih a ni).
Mechanical: mechanical hmanga chetna hmanga tih theih a ni a, spring emaw cam mechanism emaw pawh a tel thei bawk.
A hman dan tur dik tak:
5/2 directional valve hian airflow chu trade port-ah a hruai a, double-a lan dan cylinder kal dan tur a control a ni.
Hmun khatah chuan boruak chu cylinder lam hawi pakhatah a luang lut a, a sir dang atanga boruak khauh tak ang bawkin piston chu kawng khatah a nawr a.
Role dang ah chuan airflow chu reverse a ni a, chu chuan piston chu a kalh zawng kawng chhungah a kal thei a ni.
He valve hian cylinder ang chi actuators-a airflow kalna kawng chu revers-in automated technique-a hmanrua kal dan dik tak chu a manipulate thei a ni.
