Ivalvu yebhabhathane ephefumlayoyenziwe nge-actuator yomoya kunye ne-valve yebhabhathane. I-valve yebhabhathane emoya isebenzisa ipleyiti yebhabhathane ejikelezayo ejikeleza nesiqu se-valve ukuvula nokuvala, ukuze kufezekiswe isenzo sokusebenza. I-valve ye-pneumatic isetyenziswa kakhulu njenge-valve yokuvala, kwaye inokuyilwa ukuba ibe nomsebenzi wokulungisa okanye i-valve yecandelo kunye nohlengahlengiso. Okwangoku, i-valve yebhabhathane isetyenziswa kuxinzelelo oluphantsi kunye nolukhulu. Isetyenziswa ngakumbi nangakumbi kwimibhobho ephakathi.
Umgaqo wokusebenzaivalvu yebhabhathane enomoya
Ipleyiti yebhabhathane yevalvu yebhabhathane ifakwe kwicala lobubanzi bombhobho. Kwitshaneli ye-cylindrical yomzimba wevalvu yebhabhathane, ipleyiti yebhabhathane enemilo yediski ijikeleza i-axis, kwaye i-engile yokujikeleza iphakathi kwe-0°-90°Xa ukujikeleza kufikelela kwi-90°, ivalvu ikwimeko evulekileyo ngokupheleleyo. Ivalvu yebhabhathane ilula ngesakhiwo, incinci ngobukhulu kwaye ilula ngobunzima, kwaye inamacandelo ambalwa kuphela. Ngaphezu koko, inokuvulwa kwaye ivalwe ngokukhawuleza ngokujikeleza i-90 kuphela.°, kwaye ukusebenza kulula. Kwangaxeshanye, ivalvu ineempawu ezilungileyo zokulawula ulwelo. Xa ivalvu yebhabhathane ikwindawo evulekileyo ngokupheleleyo, ubukhulu bepleyiti yebhabhathane yeyona nto ixhathisayo xa i-medium idlula emzimbeni wevalvu, ngoko ke ukuhla koxinzelelo oluveliswa yivalvu kuncinci kakhulu, ngoko ke ineempawu ezilungileyo zokulawula ukuhamba. Iivalvu zebhabhathane zineentlobo ezimbini zokutywina: i-elastic seal kunye ne-metal seal. Kwiivalvu zokutywina ze-elastic, iringi yokutywina ingafakwa emzimbeni wevalvu okanye incamathiselwe kumda wepleyiti yebhabhathane.
Ivalvu yebhabhathane yomoyaukugcinwa kunye nokulungiswa kweempazamo
1. Isicwangciso sokuhlola isilinda kunye nokugcinwa kwayo
Ngokwesiqhelo yenza umsebenzi omhle wokucoca umphezulu wesilinda kunye nokuthambisa ioyile kwisangqa seshaft yesilinda. Vula isigqubuthelo sokugqibela sesilinda rhoqo rhoqo kwiinyanga ezi-6 ukujonga ukuba kukho iindawo ezahlukeneyo kunye nokufuma kwisilinda, kunye nemeko yegrisi. Ukuba igrisi yokuthambisa ayifumaneki okanye yomile, kuyimfuneko ukuyiqhaqha isilinda ukuze igcinwe kakuhle kwaye icocwe ngaphambi kokuba wongeze igrisi yokuthambisa.
2. Ukuhlolwa komzimba wevalvu
Qho emva kweenyanga ezi-6, jonga ukuba umzimba wevalvu ulungile na, ukuba kukho ukuvuza kwiflange yokuyifaka, ukuba kulungile, jonga ukuba isitywino somzimba wevalvu silungile na, akukho kugqwala, nokuba ipleyiti yevalvu iyaguquguquka na, kwaye nokuba kukho nayiphi na into yangaphandle ebambeke kwivalvu.
Iindlela zokukhupha nokuhlanganisa iibhloko zesilinda kunye namanyathelo okhuseleko:
Okokuqala susa isilinda emzimbeni wevalvu, qala ususe isigqubuthelo kuzo zombini iziphelo zesilinda, qwalasela indlela ebekwe ngayo irakhi yepiston xa ususa ipiston, uze usebenzise amandla angaphandle ukujikeleza ishaft yesilinda ngokwewotshi ukuze wenze ipiston ihambe iye kwicala elingaphandle, uze uvale ivalvu. Umngxuma ungena umoya kancinci kwaye ipiston ityhalelwa ngaphandle kancinci ngoxinzelelo lomoya, kodwa le ndlela kufuneka iqwalasele ukuphefumla kancinci, kungenjalo ipiston iya kukhupha ngequbuliso, nto leyo eyingozi kancinci! Emva koko susa i-circlip kwi-shaft yesilinda, kwaye i-shaft yesilinda ingavulwa kwelinye icala. yikhuphe. Emva koko ungacoca inxalenye nganye uze wongeze igrisi. Iindawo ekufuneka zigcotshwe zezi: udonga lwangaphakathi lwesilinda kunye neringi yesitywina sepiston, irakhi kunye neringi yangasemva, kunye neringi yegiya kunye neringi yesitywina. Emva kokuthambisa igrisi, kufuneka ifakwe ngokwendlela yokuqhaqha kunye nendlela ebuyela umva yeendawo. Emva koko, kufuneka ifakwe ngokwendlela yokuqhaqha kunye nendlela ebuyela umva yeendawo. Nika ingqalelo kwindawo yegiya kunye nerakhi, kwaye uqinisekise ukuba i-piston iyancipha ukuya kwindawo xa ivalvu ivuliwe. Umngxuma okwisiphelo esiphezulu se-gear shaft uhambelana ne-cylinder block ngexesha lendawo engaphakathi, kwaye umngxuma okwisiphelo esiphezulu se-gear shaft umi nkqo kwi-cylinder block xa i-piston yoluliwe ukuya kwindawo engaphandle xa ivalvu ivaliwe.
Iindlela zokufakela kunye nokulungisa iingxaki kunye namanyathelo okhuseleko:
Okokuqala faka ivalvu kwimeko evaliweyo ngamandla angaphandle, oko kukuthi, jika ivalvu shaft ngokwewotshi de ipleyiti yevalvu ivalwe inxibelelane nesihlalo sevalvu, kwaye kwangaxeshanye beka isilinda kwimeko evaliweyo (oko kukuthi, ivalvu encinci ngaphezulu kwe-shaft yesilinda. Umngxuma umi nkqo emzimbeni wesilinda (kwivalvu ejikeleza ngokwewotshi ukuvala ivalvu), uze ufake isilinda kwivalvu (icala lokufakelwa lingaba lihambelana okanye limi nkqo emzimbeni wevalvu), uze ujonge ukuba imingxunya yesikrufu ilungelelanisiwe na. Ukuphambuka okukhulu, ukuba kukho ukuphambuka okuncinci, jika nje ibhloko yesilinda kancinci, uze uqinise izikrufu. Ukulungisa ivalvu yebhabhathane ye-pneumatic kuqala jonga ukuba izixhobo zevalvu zifakwe ngokupheleleyo, ivalvu ye-solenoid kunye ne-muffler, njl., ukuba ayigqitywanga, musa ukulungisa, uxinzelelo lomoya oluqhelekileyo yi-0.6MPA±I-0.05MPA, ngaphambi kokusebenza, qiniseka ukuba akukho nkunkuma ibambeke kwipleyiti yevalvu emzimbeni wevalvu. Kwinkqubo yokuqala yokusebenza, sebenzisa iqhosha lokusebenza ngesandla levalvu yesolenoid (ikhoyili yevalvu yesolenoid iyasebenza ngexesha lokusebenza ngesandla, kwaye ukusebenza ngesandla kuyasebenza; xa kwenziwa umsebenzi wolawulo lombane, ukujika ngesandla kumiselwa kwi-0 kwaye ikhoyili iyasebenza, kwaye ukusebenza ngesandla kuyasebenza; isikhundla se-0 kukuvala ivalvu, i-1 kukuvula ivalvu, oko kukuthi, ivalvu ivuliwe xa umbane uvuliwe, kwaye ivalvu ivaliwe xa umbane ucinyiwe.
Ukuba kufunyaniswe ukuba umenzi wevalvu yebhabhathane ephefumlayo uhamba kancinci kwindawo yokuqala yokuvulwa kwevalvu ngexesha lokuqaliswa nokusebenza kwayo, kodwa ikhawuleza kakhulu xa ishukuma. Ngokukhawuleza, kule meko, ivalvu ivaliwe kakhulu, lungisa nje ukubetheka kwesilinda kancinci (lungisa izikrufu zokulungisa ukubetheka kuzo zombini iziphelo zesilinda kancinci ngaxeshanye, xa ulungisa, ivalvu kufuneka ifuduselwe kwindawo evulekileyo, uze emva koko umthombo womoya ucinywe. Yicime uze uyilungise), lungisa ide ivalvu ibe lula ukuyivula nokuyivala endaweni yayo ngaphandle kokuvuza. Ukuba i-muffler iyalungiseka, isantya sokutshintsha sevalvu sinokulungiseka. Kubalulekile ukulungisa i-muffler kwindawo efanelekileyo yokuvulwa kwesantya sokutshintsha ivalvu. Ukuba uhlengahlengiso luncinci kakhulu, ivalvu ayinakusebenza.
