Ivalve yomlinganiso wombane ekubhekiswa kuyo njengevalve yolungelelwaniso.Uphawu lwayo kukuba ubungakanani bemveliso butshintsha kunye nobungakanani begalelo.Kukho unxulumano oluthile phakathi kwemveliso kunye negalelo, ngoko kubizwa ngokuba yivalve yombane yombane.

I-valve yokulinganisa iqulunqwe yi-electro-mechanical converter kunye ne-pneumatic amplifier, kwaye yinkqubo yokulawula i-loop evaliweyo.Inkqubo ngokuqhubekayo ibona imveliso (uxinzelelo) ekupheleni kwemveliso kwaye iyondla emva kwesiphelo segalelo lenkqubo ngokuthelekisa negalelo (kufuneka ixabiso).Xa ixabiso langempela lemveliso (ixabiso loxinzelelo) liphambuka kwigalelo (ixabiso elilindelekileyo), inkqubo ilungisa ngokuzenzekelayo imveliso ukuze itshintshe ulwalathiso olusondeleyo kwigalelo, ukwenzela ukuba kuqinisekiswe ukuba imveliso izinzile ngaphakathi kwexabiso loxinzelelo olufunekayo. ngegalelo.Gcina ubudlelwane obulinganayo phakathi kwemveliso kunye negalelo.

Iimbonakalo:

Uxinzelelo lwemveliso lutshintsha kunye nomqondiso wegalelo, kwaye kukho umlinganiselo othile

ubudlelwane phakathi koxinzelelo lwemveliso kunye nomqondiso wegalelo.

Ngobuchule bokulawula amandla ombane ongenanyathelo.

Ngokukwazi ukulawula okude kunye nokulawulwa kweprogram: ixabiso elifanelekileyo le-valve yokulinganisa libekwe ngonxibelelwano, ukuhanjiswa kwesignali yokulawula kude kuzinzile, kwaye umgama wokulawula unokwandiswa.Inokubonwa ngePC, i-chip microcomputer enye, iPLC kunye nezinye izixhobo.

Phawula:

1. Ngaphambi kokuba i-valve yokulinganisa yombane, isihluzo somoya kunye ne-oyile ye-mist separator kunye nokuchaneka kwe-filtration ye-5μm okanye ngaphantsi kufuneka ifakwe.Ukubonelela ngomoya ococekileyo kunye nowomileyo oxinzelelweyo kwi-valve yokulinganisa ukuze ufezekise iimpawu ezahlukeneyo zevalve yombane.

2. Ngaphambi kofakelo, umbhobho kufuneka ucocwe.

3. Akukho lubricator kufuneka ifakwe ngaphambili ekupheleni kwevalve yokulinganisa.

4. I-valve elinganiselayo inqumla ukunikezelwa kwamandla kwimeko yoxinzelelo, kwaye uxinzelelo kwicala lokuphuma lunokugcinwa okwethutyana, olungaqinisekanga.Ukuba ufuna ukukhupha umoya, cima umbane emva kokuthoba uxinzelelo olusetiweyo, kwaye usebenzise ivalve yokukhulula uxinzelelo ukuze uvule.

5. Kwimeko yokulawula i-valve yokulinganisa, uxinzelelo kwicala lokuphuma lunokugcinwa kanye ngenxa yokungaphumeleli kwamandla okanye enye ilahleko yamandla.Ukongezelela, xa icala lokuphuma livulelwa emoyeni, uxinzelelo luya kuqhubeka luhla kuxinzelelo lwe-atmospheric.

Emva kokuba i-valve yokulinganisa inikwe amandla, ukuba uxinzelelo lokubonelela lunqunyulwe, i-valve ye-solenoid iya kuqhubeka isebenza, eya kuvelisa isandi esiphumayo kunye nokunciphisa ubomi bayo.Ngoko ke, ukunikezelwa kwamandla kufuneka kunqunyulwe xa umthombo wegesi unqunyulwa, ngaphandle koko i-valve yokulinganisa iya kungena "kwimeko yokulala".

6. Imveliso ye-valve ye-proportional ihlengahlengiswe ngaphambi kokuba ushiye i-factory, nceda ungayihluli ukuze ugweme ukungasebenzi.

7. Xa i-valve yokulinganisa ingasebenzisi imveliso yokubeka iliso (i-switch output), i-monitor output wire (i-black wire) ayikwazi ukudibanisa nezinye iingcingo ukuphepha ukungasebenzi.Ukusetyenziswa kwemithwalo ye-inductive (i-solenoid valves, i-relays, njl.) kufuneka ibe nemilinganiselo yokufunxa ngaphezulu kwe-voltage.

8. Kuphephe ukungasebenzi kakuhle okubangelwa yingxolo yombane.Le mveliso kunye ne-wiring yayo kufuneka ibe kude nemoto kunye nomgca wamandla ukuze ugweme impembelelo yengxolo yamanqaku.

9. Xa icala eliphumayo linomthamo omkhulu kunye nomsebenzi ogqithisiweyo usetyenziswa njengenjongo, ingxolo yokukhupha ikhulu ngexesha lokugqithisa, kwaye i-port yokukhupha kufuneka ixhotywe nge-silencer.

10. Xa ixabiso elilindelekileyo lingaphantsi kwe-0.1V, lithathwa njenge-0V.Kule meko, uxinzelelo oluphumayo lusetelwe kwi-0 Bar ngokuvula i-valve yokukhupha kwaye igesi kwigumbi le-valve ehambelanayo iphelile.

11. Ngaphambi kokuba unqumle ukunikezelwa kwamandla e-valve elinganayo, nceda uqiniseke ukuba unqamle umbane wexabiso (ngaphantsi kwe-0.1V), uze unqumle uxinzelelo lomthombo womoya, kwaye ekugqibeleni unqumle ukunikezelwa kwamandla e-valve yokulinganisa.

12. Iimfuno zomthombo wegesi: uxinzelelo lwegalelo kufuneka lube lukhulu kunoxinzelelo lwemveliso ngaphezu kwe-0.1MP, kwaye luhlangabezane nokusetyenziswa kwerhasi iyonke, oko kukuthi, ukuhamba kwegalelo kungaphezulu kokuphuma kwemveliso.
