Ivalve yebhabhathane yepneumaticyenziwe nge-actuator yomoya kunye nevalve yebhabhathane. Ivalve yebhabhathane yepneumatic isebenzisa ipleyiti yebhabhathane ejikelezayo nesiqu sevalve ukuze ivuleke kwaye ivalwe, ukuze kuqatshelwe isenzo sokuvula. I-valve ye-pneumatic isetyenziswa kakhulu njenge-valve yokuvala, kwaye inokuthi yenziwe ukuba ibe nomsebenzi wohlengahlengiso okanye i-valve yecandelo kunye nohlengahlengiso. Okwangoku, i-valve ye-butterfly isetyenziselwa uxinzelelo oluphantsi kunye nobukhulu Isetyenziswa ngakumbi nangakumbi kwimibhobho ephakathi.
Umgaqo wokusebenza weivalve yebhabhathane yepneumatic
Ipleyiti yebhabhathane yevalve yebhabhathane ifakwe kwicala elinobubanzi bombhobho. Kumjelo wecylindrical womzimba wevalve yebhabhathane, ipleyiti yebhabhathane emile okwediski ijikeleza iaxis, kwaye i-engile yokujikeleza iphakathi kwe-0.°-90°. Xa ukujikeleza kufikelela kwi-90°, ivalve ikwimo evuleke ngokupheleleyo. Ivalve yebhabhathane ilula kwisakhiwo, incinci ngobukhulu kwaye ilula ngobunzima, kwaye iqulathe iinxalenye ezimbalwa kuphela. Ngaphezu koko, inokuvulwa ngokukhawuleza kwaye ivalwe ngokujikeleza kuphela i-90°, kwaye umsebenzi ulula. Kwangaxeshanye, ivalve ineempawu ezilungileyo zokulawula ulwelo. Xa ivalve yebhabhathane ikwindawo evuleleke ngokupheleleyo, ubukhulu bepleyiti yebhabhathane yeyona nto ixhathisayo xa i-medium iqukuqela kumzimba wevalve, ngoko ke ukuhla koxinzelelo okwenziwa yivalve kuncinci kakhulu, ngoko ke ineempawu zokulawula ukuhamba kakuhle. Iivalve zebhabhathane zineentlobo ezimbini zokutywina: isitywina esilastiki kunye nesitywina sentsimbi. Kwiivalvu zokutywina ezilastiki, umsesane wokutywina unokufakwa kumzimba wevalvu okanye uncanyathiselwe kumda wepleyiti yebhabhathane.
Ivalve yebhabhathane yepneumaticukugcinwa kunye nokulungiswa kweempazamo
1. Ukuhlolwa kwe-cylinder kunye nesicwangciso sokulondoloza
Ngokuqhelekileyo yenza umsebenzi omhle wokucoca umphezulu we-cylinder kunye nokugcoba i-circlip ye-cylinder shaft. Vula isiciko sesiphelo se-cylinder rhoqo emva kweenyanga ezi-6 ukujonga ukuba ngaba kukho i-sundries kunye nokufuma kwi-cylinder, kunye nemeko yegrisi. Ukuba igrisi yokuthambisa ilahlekile okanye yomile, kuyimfuneko ukuqhawula isilinda ukuze ugcinwe ngokupheleleyo kunye nokucoca ngaphambi kokuba ungeze igrisi yokuthambisa.
2. Ukuhlolwa komzimba weValve
Rhoqo kwiinyanga ezi-6, khangela ukuba imbonakalo yomzimba wevalve ilungile, ingaba kukho ukuvuza kwi-flange yokunyuka, ukuba ifanelekile, khangela ukuba itywina lomzimba wevalve lilungile, akukho mpahla, nokuba ipleyiti yevalve iyaguquguquka, kunye nokuba kukho nawuphi na umcimbi wangaphandle obambekayo kwivalve.
Ukuqhawulwa kwebhloko yesilinda kunye neendlela zokuhlanganisa kunye nezilumkiso:
Okokuqala susa isilinda kumzimba wevalve, susa kuqala isigqubuthelo kuzo zozibini iziphelo zesilinda, nikela ingqalelo kwicala le-piston rack xa ususa ipiston, emva koko usebenzise amandla angaphandle ukujikelezisa i-cylinder shaft ngasekunene ukwenza ipiston ibaleke ukuya. icala elingaphandle, kwaye emva koko uvale ivalve Umngxuma uphuma umoya ngokucothayo kwaye ipiston ityhilwe ngaphandle ngokucokisekileyo ngoxinzelelo lomoya, kodwa le ndlela kufuneka inikele ingqalelo kwi-ventilate kancinane, kungenjalo i-piston iya kukhupha ngokukhawuleza, eyingozi kancinane! Emva koko susa i-circlip kwi-cylinder shaft, kwaye i-cylinder shaft inokuvulwa ukusuka kwelinye icala. yikhuphe. Emva koko unokucoca inxalenye nganye kwaye ungeze igrisi. Amalungu afuna ukufakwa igrisi ngala: udonga lwangaphakathi lwesilinda kunye neringi yepiston, i-rack kunye ne-back ring, kunye ne-gear shaft kunye neseyile yokutywina. Emva kokuthambisa igrisi, kufuneka ifakwe ngokuhambelana nomyalelo wokuqhawula kunye nolandelelwano lwamacandelo. Emva koko, kufuneka ifakwe ngokuhambelana nomyalelo wokuqhawula kunye ne-reverse order yamacandelo. Nika ingqalelo indawo yegiya kunye ne-rack, kwaye uqinisekise ukuba ipiston iyancipha kwindawo xa i-valve ivuliwe. I-groove kwisiphelo esiphezulu se-gear shaft ihambelana nebhloko ye-cylinder ngexesha lendawo engaphakathi, kwaye i-groove ekupheleni kwe-shaft ye-gear i-perpendicular kwi-cylinder block xa i-piston isolulelwe kwindawo engaphandle kakhulu xa ivalve. ivaliwe.
Ufakelo lwe-cylinder kunye nevalve yomzimba kunye neendlela zokulungisa kunye nezilumkiso:
Okokuqala faka ivalve kwindawo evaliweyo ngamandla angaphandle, oko kukuthi, jikela i-valve shaft ngasekunene de ipleyiti yevalve idityaniswe nesitulo sevalvu, kwaye kwangaxeshanye ubeke isilinda kwindawo evaliweyo (oko kukuthi, ivalve ikwindawo evaliweyo). ivalve encinci ngaphezu kwe-cylinder shaft I-groove i-perpendicular kumzimba we-cylinder (i-valve ejikeleza i-clockwise ukuvala i-valve), uze ufake i-cylinder kwi-valve (ulwalathiso lofakelo lunokuhambelana okanye kwi-perpendicular kumzimba wevalve), kwaye emva koko khangela ukuba imingxuma Screw ilungelelanisiwe, ukuba kukho ukutenxa kancinci, jika nje ibhloko yesilinda kancinci, kwaye emva koko uqinise izikrufu zevalve yebhabhathane kuqala ujonge ukuba izincedisi zevalve zifakwe ngokupheleleyo kunye ne-muffler, njl., ukuba ayigqitywanga, musa ukulungisa ingxaki, uxinzelelo lomoya oluqhelekileyo luyi-0.6MPA±I-0.05MPA, ngaphambi kokuba usebenze, qiniseka ukuba akukho nkunkuma ebanjwe kwi-plate ye-valve kumzimba we-valve Ekuthumeni kokuqala kunye nokusebenza, sebenzisa iqhosha le-manual yokusebenza kwe-valve ye-solenoid (i-coil ye-solenoid ivaliwe ngexesha lokusebenza ngesandla, kunye nokusebenza ngesandla kuvumelekile xa umsebenzi wokulawula umbane wenziwa, i-twist manual ifakwe kwi-0 kwaye i-coil inikwe amandla, kwaye umsebenzi we-manual uvumelekile ukuvala i-valve, i-1 kukuvula i-valve; oko kukuthi, i-valve ivuliwe xa amandla evuliwe, kwaye i-valve ivaliwe xa umbane uvaliwe.
Ukuba kufunyaniswe ukuba umenzi wevalve yebhabhathane yepneumatic ucotha kakhulu kwindawo yokuqala yokuvula ivalve ngexesha lokugunyaziswa kunye nokusebenza, kodwa ikhawuleza kakhulu ngokukhawuleza xa ihamba. Ngokukhawuleza, kule meko, i-valve ivalwe ngokuqinileyo, lungisa nje ukubetha kwe-cylinder kancinane (lungisa izikhonkwane zohlengahlengiso lwe-stroke kuzo zombini iziphelo zesilinda kancinci ngexesha elinye, xa uhlengahlengisa, ivalve kufuneka ihanjiswe. kwindawo evulekileyo, kwaye ke umthombo womoya kufuneka ucinywe Yicime kwaye emva koko ulungelelanise), lungisa kude kube lula ukuvula nokuvala indawo ngaphandle kokuvuza. Ukuba i-muffler iyahlengahlengiswa, isantya sokutshintsha i-valve sinokulungiswa. Kuyimfuneko ukulungelelanisa i-muffler kwindawo efanelekileyo yokuvula isantya sokutshintsha i-valve. Ukuba uhlengahlengiso luncinci kakhulu, ivalve ayinakusebenza.
