Indawo ekuyo
Izinto ze-actuator yomoya kufuneka zifaniswe ne-actuator xa isetyenziswa. Inokuphucula ukuchaneka kokuma kwevalve kwaye inciphise ifuthe lokunyanzelwa kwesitshixo sevalve kunye namandla angalinganiyo aphakathi, ukuze kuqinisekiswe ukubekwa ngokuchanekileyo kwevalve ngokungqinelana nomqondiso onikezwe ngumlawuli. Kuphantsi kwaziphi iimeko ekufuneka uqwalasele indawo yokuma kwindawo yomoya wevalve yolawulo lokuhamba:
1. Xa uxinzelelo oluphakathi luphezulu kwaye umahluko woxinzelelo mkhulu;
2. Xa ubukhulu bevelufa elawulayo bukhulu kakhulu (DN> 100);
3. Ubushushu obuphezulu okanye ubushushu obuphantsi bokulawula i-valve;
4. Xa kufuneka kunyuswe isantya sokusebenza kwevalve elawulayo;
5. Xa kufuneka ukwahlulahlulahlulahlula ulawulo;
6. Xa kufuneka umqondiso osemgangathweni ukuze usebenze i-actuator yasentwasahlobo engaqhelekanga (uluhlu lwentwasahlobo lungaphandle kwama-20 ～ 100KPa);
7. Xa uqaphela isenzo esiphindayo sevalve (uhlobo lokuvala umoya kunye nohlobo oluvulekileyo lomoya luyatshintshana);
8. Xa iimpawu zokuhamba kwevalve elawulayo kufuneka zitshintshwe (indawo yokuma kweekhamera inokutshintshwa);
9. Xa kungekho msasazi wentwasahlobo okanye ipiston actuator, kunyanzelekile ukuba kufezekiswe amanyathelo alinganayo;
10. Xa usebenzisa imiqondiso yombane ukusebenzisa izixhobo ezisebenza ngumoya, amandla makasasazwe kwindawo yomoya yevali yomoya.
Ivelufa yombane
Xa le nkqubo ifuna ukufezekisa ulawulo lwenkqubo okanye ulawulo lwezikhundla ezimbini, kufuneka ixhotyiswe ngevalvenoid valve. Xa ukhetha ivelufa yentsimbi, ukongeza ekuqwalaseleni unikezelo lwamandla lwe-AC kunye ne-DC, ombane kunye nobuninzi, ingqalelo kufuneka ihlawulwe kubudlelwane phakathi kwe-valve ye-solenoid kunye nevalve elawulayo. Ngokwesiqhelo ukuvula okanye ukuvala ngesiqhelo kunokusetyenziswa.
Ukuba ufuna ukwandisa umthamo we-valve ye-solenoid ukunciphisa ixesha lesenzo, ungasebenzisa ii-valves ezimbini ze-solenoid ngokufanayo okanye usebenzise i-valve ye-solenoid njenge-valve yokuqhuba ngokudibanisa ne-pneumatic relay enkulu.
Ipakethi yomoya
Ipayipi le-pneumatic luhlobo lwesikhulisi samandla, esinokuthi sithumele isiginali yoxinzelelo lomoya kwindawo ekude, isuse i-lag ebangelwe kukwandiswa kombhobho wesiginali. Isetyenziswa ikakhulu phakathi komhambisi wentsimi kunye nesixhobo esilawulayo kwigumbi lolawulo eliphakathi, okanye phakathi komlawuli kunye nevalve yentsimi elawula umhlaba. Omnye umsebenzi kukwandisa okanye ukunciphisa umqondiso.
Isiguquli
Isiguquli sahlulahlulwe saba sisiguquli segesi-sombane kunye nesiguquli-sombane-sombane, kwaye umsebenzi waso kukuqonda ukuguqulwa kokudibana kobudlelwane obuthile phakathi kweempawu zombane zerhasi nezombane. Xa usebenzisa imiqondiso yombane ukwenza i-pneumatic actuators, isiguquli sinokuguqula imiqondiso eyahlukeneyo yombane kwiimpawu ezahlukeneyo zomoya.
Uxinzelelo lwefilitha yomoya ukunciphisa ivalve
Uxinzelelo lwefilitha yomoya yokunciphisa ivalve yinto yokufikelela kwizixhobo ezizisebenzelayo zeshishini. Umsebenzi wayo ophambili kukucoca kunye nokucoca umoya oxineneyo ukusuka kwisiguquli somoya kunye nokuzinzisa uxinzelelo kwixabiso elifunekayo. Ingasetyenziselwa izixhobo ezahlukeneyo zomoya kunye neevalvu ze-solenoid. , Ukubonelelwa komoya kunye necebo lokuzinzisa ombane weesilinda, izixhobo zokutshiza kunye nezixhobo ezincinci zomoya.
Ivalufa yakho yokuzimela (indawo yevalufa)
Isivalo sokuzivala sisixhobo esigcina indawo yevalve. Xa umthombo womoya ungaphumeleli, isixhobo sinokususa isitshixo somthombo womoya ukugcina uxinzelelo lwegumbi le-membrane okanye isilinda kurhulumente kwangoko ngaphambi kokungaphumeleli, ke indawo yevalve nayo igcinwe kwindawo ngaphambi kokungaphumeleli.
Indawo yokuhambisa ivalve
Xa ivelufa elawulayo ikude kude negumbi lolawulo, ukuze uqonde ngokuchanekileyo indawo yokutshintsha kwevalve ngaphandle kwesiza, kufuneka uxhobise indawo yokuhambisa ivalve. Isiginali inokuba sisiginali eqhubekayo ebonisa nakuphi na ukuvulwa kwevalve, okanye inokuthathwa njengentshukumo ebuyela umva yesimeli sevalve.
Utshintsho lokuhamba (umphenduli)
Ukutshintsha kokuhamba kubonakalisa ezi ndawo zimbini zigqithileyo zeswitshi yevalve kwaye ithumele uphawu lokubonisa ngaxeshanye. Ngokusekwe kulo mqondiso, igumbi lolawulo linokucima imeko yokutshintsha kwevalve ukuze uthathe amanyathelo ahambelanayo.
