Ivalvu yokulawula ethile ye-5/2iyindlela yokulawula umoya ezinsizakalweni ze-pneumatic, ikakhulukazi ekuqaliseni ama-silinda amabili. I "five" ibhekisela enanini lezi zikhala (izixhumanisi), futhi i "2" ibhekisela enanini lezindawo (izimo i-valve ingaba kuzo). Nansi indlela esebenza ngayo:
Izinto ezibalulekile ze-Valve engu-5/2:
Iziphathamandla ezi-5:
P (ukucindezela): Iphothi ephathelene nokuhlinzekwa komoya.
A: Iphothi exhumene ku-1 facet ye-silinda (noma i-actuator).
B: Iphoyinti lihlanganiswe nendawo ephikisana ne-cylindar (noma i-actuator).
EA (Ukukhishwa A): Ithafa lokukhishwa komoya eliphuma kumphakathi ngenkathi i-valve iguquka endleleni eyodwa.
EB (Ukukhishwa B): Ithafa lokukhishwa komoya ohamba ngaphakathi komsebenzi ngenkathi i-valve iguquka endleleni ephambene.
2 Izikhala:
Ivalvu inezikhala ezi-2 ezishintshashintshayo indlela yokuhamba komoya, ukuphatha ukuthi umoya ungene kanjani futhi uphume kanjani kumsebenzisi.
indlela esebenza ngayo:
inenkanyezi 1 (umsebenzi wokuphumula / De-ukukhulula):
Nxa i-valve ingasetyenziswa (noma ngaphakathi kwenqubo yayo 'yokuphumula'), ama-port ahlelwe ngendlela elandelayo:
I-Port P (ukulethwa ngenqola) ixhuma ku-Port A (ukuveza okukodwa kwe-cylinder).
I-Phothi B (okuqhathaniswa ne-cylinder) ixhunywe ku-Exhaust Port EA, evumela umoya ukuthi uphume emshinini.
Iphothi EB ivaliwe, yokumela umoya ungaphumi kwiPhothi B.
Le nkqubo iphonsa i-piston ngaphakathi kwe-cylinder iye kwelinye icala (isb., ukwandisa i-piston).
indawo 2 (Indawo evuthayo / Ehlanganisiwe):
nokuqhubeka lapho ivali ivuliwe (isibonelo, uma i-solenoid ivuliwe), imishini yangaphakathi ishintsha ivali iye endaweni yayo yesibili, ishintsha imigwaqo ye-float:
I-Port P (ukuphakelwa komoya) manje ixhuma ku-Port B, ithumela umoya ohlangothini oluphambene lwe-silinda.
Iphothi A manje isixhumiwe ne-Exhaust Port EB, ivumela umoya ukuphuma ngaphandle kwendawo eshisayo ye-silinda.
Iphothi ye-EA ivaliwe.
Le nsizakalo ihambisa ipistoni ngaphakathi kwesixhumanisi esiphambene (isb., ukunciphisa ipistoni).
phatheka phansi ku 5/2 Valve:
Imbangela ye-valve engu-5/2 ukuhlela ukuhamba komoya ngendlela oshintsha ngayo izindlela zesilinda esine-2 esisebenzisanayo:
ERole 1, umoya uqondiswa endaweni eyodwa ye-silinda (kukhuluma ngePort A), kanti umoya ngakolunye uhlangothi (Port B) ukhishwa nge-EA.
Endaweni 2, indlela yomoya iyaguqulwa: umoya uthunyelwa kwenye icala le-cylindrical (ngaphambi kwe-Phumu B), kanti umoya ngelinye icala le-cylindrical uphume ngakolunye uhlangothi nge-EB.
izinhlelo ezivamile:
Ama-Cylinder amabili- aphakanyisiwe: I-5/2 valve ivamise ukusetshenziswa namacylinders aphakanyisiwe amabili-, lapho i-piston ifuna ukuhamba phambili nasekuphakanyiseni (ukwandisa nokuhoxisa) ngokusebenzisa umoya oshintshashintshayo ngasohlangothini lwe-piston.
Izakhiwo zokwakha: ama-valve amahlanu/2 abekwe ezakhiweni ezizenzakalelayo njengezinto zokuhamba, izinhlelo zokufakwa, nemishini yokupakisha, lapho kudingeka khona ukunqunywa, ukujikeleza okuphindaphindiwe.
izitayela zokusebenza ze-5/2 Valve:
imanual: Iphawulwe ngosizo lwe-lever yokuhola, inkinobho, noma ukudlulisela.
Isolenoid-Isebenza: Ivulwa ngokuqondiswa kwentambo ye-solenoid, okuyi-ukuphathwa ngogesi.
Iphumuzayo: Ikhuthazwa indlela yokusebenzisa enye isignali yephumuzo (ejwayele ukwaziwa njengephayiphi elilawulwayo noma elisebenzelwa iphayiphi).
Imishini: ingase iqhutshwe ngokuqhuba ngezindlela zomshini, kufaka phakathi umgibeli noma indlela yokwakha.
ukuhlanganiswa kokusebenza:
Ivalve ye-5/2 yokuhambisa ithumela umoya emaphephandabeni, ilawula ukuhamba kwesilinda esiphindwe kabili.
endaweni eyodwa, umoya uyagcwala engxenyeni eyodwa yesilinda, uqinisekisa ukunyakaza komshayeli ngendlela eyodwa nakuba umoya onamandla uvela ngakolunye uhlangothi.
kwelinye ibhodi, umoya we-air ushintshwe, uvumela i-piston ukuthi ihambe ngaphakathi kwamahamba aphikisanayo.
Le valve ivumela ukuphatha ukuhamba okufanele kwezinsiza kumathuluzi okuzenzakalelayo ngokuphendula indlela yokuhamba komoya ukuya kumasimu afana nezindandatho.
