Ivalve yombane iingxaki eziqhelekileyo zikufundisa ukhetho oluchanekileyo lwevalve yombane kunye nevalve yepneumatic kunye noncedo kunye nokungalunganga kweentlobo ezimbini zeevalvu.

Isiphumo sesikali

Ingaba i-valve ye-solenoid okanye i-valve yombane, isikali asiyi kubangela ukuvuza kwevalve kuphela, kubi kakhulu nokuba kuchaphazela umsebenzi oqhelekileyo wevalve, ngoko ke indlela yokuphelisa impembelelo yesikali, iye yaba yinkxalabo eqhelekileyo kwishishini.

Umsebenzi wevalvu yokulawula umbi

Inkqubo yevalve ye-Solenoid ukubandakanya ububanzi bubanzi kakhulu, kodwa ngenxa yokuba uyilo lwe-actuator kunye nokusetyenziswa kwezinto zokuzalisa ezibangelwa ngumsebenzi ombi we-valve yokulawula isenokushwankathelwa imithetho yayo.

Ubukho beendawo ezifileyo kwinkqubo buya kubangela ukuba inkqubo eguquguqukayo ijike kwindawo yokuqala. Ke isiphumo somlawuli kufuneka sandiswe ngokwaneleyo ukoyisa indawo efileyo ukuze kwenzeke esi senzo solungiso.

Izinto eziphambili ezichaphazela indawo efileyo:

① Ukukhuhlana, ukukhukuliseka, ivalve shaft torsion, indawo efileyo yeamplifier. Iivalvu zokulawula zinovelwano kukukhuhlana ngeendlela ezahlukeneyo. Iivalvu ezijikelezayo, umzekelo, zinovakalelo kwi-friction ebangelwa ngumthwalo wesitulo esiphezulu, ngoko qaphela oku xa usebenzisa. Kwamanye amatywina, nangona kunjalo, umthwalo wesihlalo esiphezulu uyimfuneko ukufezekisa iklasi yokutywina. Ngenxa yoko, i-valve ayilungiswanga kakuhle kwaye ibangela ngokulula indawo enkulu efileyo, enempembelelo ecacileyo kunye nesigqibo esicacileyo kwiqondo lokutenxa kwenkqubo.

② Ukunxiba nokukrazula. Ukunxitywa kwevalve akunakuphepheka kusetyenziso oluqhelekileyo, kodwa ukunxitywa komgangatho wokuthambisa kuqatha, ngokobungqina bovavanyo, ivalve yokuthambisa ejikelezayo kuphela ngamakhulu okuphindukuzalwa kwesenzo, umaleko wokuthambisa awunakusetyenziswa ngokulula. Ukongeza, umthwalo obangelwa uxinzelelo unokukhokelela ekunxibeni kwetywina, eyona nto iphambili ekunyuseni ukungqubana. Isiphumo yivalve yokulawula eyonakalisayo

(3) Ukupakisha ukupakisha ngowona mthombo oyintloko we-valve yokulawula i-valve, ukusetyenziswa kokupakisha okuhlukeneyo, okubangelwa ukungafani okukhulu kwingxabano.

(4) Iindidi ezahlukeneyo ze-actuator nazo zinefuthe elisisiseko kumandla okubetha. Ngokubanzi, ii-actuator zefilimu zasentwasahlobo zingcono kunee-piston actuators.

Zifundise ukhetho oluchanekileyo lwevalve yombane kunye nevalve ye-pneumatic kunye nezinto eziluncedo kunye nezingeloncedo zeentlobo ezimbini zeevalvu Ivalve yombane eqhutywa ngumbane, kwiimfuno zobungqina bokuqhuma kwesi sihlandlo ayifanelekanga, njengokusingqongileyo okukufutshane kunye nenani elikhulu ngokulula. igesi edayiweyo, unokuthembela kuphela kwi-pneumatic. Ixesha lokuphendula lomoya licotha kunombane, alichanekanga njengombane, ivalve ye-pneumatic ingamandla omoya. Ivalve yombane iguqulwa ibe yi-electromagnetic energy njengamandla, i-agility yevalve yombane iphezulu kune-valve ye-pneumatic, ukhuseleko kunye nokuthembeka akunamandla njengevalve ye-pneumatic, ukugcinwa akukho lula njengevalve yepneumatic. , amandla awanamandla njengevalve ye-pneumatic.

1. Ivalve yombane isebenzisa imotor njengamandla, kwaye ivalve yepneumatic isebenzisa umoya ocinezelweyo njengamandla.

1. Izinto eziluncedo zevalvu yombane: Impembelelo entle kulwelo oluphakathi kunye nerhasi enkulu yerhasi, engachatshazelwanga yimozulu. Ayichatshazelwa luxinzelelo lomoya.

Izinto ezingeloncedo: ixabiso eliphezulu, alilunganga kwindawo efumileyo.

2. Izinto eziluncedo zevalve ye-pneumatic: Isiphumo esihle kwi-gas medium and small diameter liquid, ixabiso eliphantsi kunye nokugcinwa lula.

Ukungalungi: Ukuchaphazeleka ngokuguquguquka koxinzelelo lomoya, kulula ukuchatshazelwa ngumoya womoya kunye namanzi omoya kubusika obusenyakatho, okubangelwa yiqhwa kwaye akukho senzo sesebe lokuhambisa.

Indlela yokukhetha ivalve yombane kunye nevalve yepneumatic ngokuchanekileyo

Isibini, i-pneumatic jikelele ikhawuleza kunombane, umbane usetyenziselwa kabini isibane. Kwaye i-pneumatic esandleni, ixabiso lokusebenzisa igesi kabini liphezulu.

Eyesithathu, ivalve yombane isetyenziswa kwezinye iindawo ezinobubanzi obukhulu, kuba i-pneumatic inzima ukuyenza, kodwa ivalve yombane ayinayo i-chaotic njenge-pneumatic, isantya sokutshintsha sicotha, i-actuator iya kubambelela ixesha elide. Ukutshintsha kwevalve yepneumatic ngokukhawuleza, ukuchaneka okuphezulu, kodwa akufuneki siphithiphithi somthombo womoya.

Okwesine, intshukumo yevalve yombane ecothayo ivelufa yombane inokwenza uphawu lobungqina bokudubula aluninzi; Intshukumo yevalve yepneumatic iyakhawuleza, ixabiso elinobungqina bokudubula kunomzantsi wombane (i-hub ivelufa ye-pneumatic eneziphi izincedisi, ezinezincedisi zophawu olukhulu ziya kuba zibiza kakhulu kunevalve yombane).

Iivalve ezibandakanyekayo ekudibaneni zikwangumbane. Ngoba?

I-1, ngokwemozulu yendawo, ukuba imozulu imanzi, i-valve ye-pneumatic ayikwazi ukusetyenziswa, kuba umthombo womoya unamanzi.

I-2, i-valve yombane inokuqonda kwakhona umsebenzi odibeneyo ngaphandle kokunyuka okongeziweyo kokusetyenziswa, i-pneumatic interlocking iya kwandisa i-valve yokugcina, inyuse iindleko.

Izinto ezilungileyo kunye nokungalunganga kwevalve yombane kunye nevalve yepneumatic:

Ngaphantsi kweziphi iimeko ezifunekayo ukusebenzisa i-valve yombane ngaphandle kwe-pneumatic, xa imfuneko yokusebenzisa i-pneumatic ngaphandle kwe-valve yombane, phakathi kwabo yintoni inzuzo kunye nokungonakali, ixabiso. Umgama wentshukumo yevalve yepneumatic mkhulu kunevalve yombane, isantya sokutshintsha ivalve yepneumatic inokulungiswa, ulwakhiwo olulula, kulula ukusigcina, kwinkqubo yesenzo ngenxa yeempawu zesithinteli segesi ngokwayo, akulula ukuba sonakaliswe. i-jamming, kodwa kufuneka ibe nomthombo womoya, kwaye inkqubo yayo yokulawula inzima ngakumbi kunevalve yombane.

Ivalve yombane iqhutywa ngumbane, engafanelekanga kwithuba leemfuno zobungqina bokuqhuma. Xa inani elikhulu leegesi ezidaywe ngokulula zisasazwa kwindawo ekufutshane, inokuxhomekeka kuphela kwi-pneumatic. Ixesha lokuphendula lomoya licotha kunombane, alichanekanga njengombane, ivalve ye-pneumatic ingamandla omoya. Ivalve yombane iguqulwa ibe yi-electromagnetic energy njengamandla, i-agility yevalve yombane iphezulu kune-valve ye-pneumatic, ukhuseleko kunye nokuthembeka akunamandla njengevalve ye-pneumatic, ukugcinwa akukho lula njengevalve yepneumatic. , amandla awanamandla njengevalve ye-pneumatic.

Ulawulo lwevalve ye-pneumatic lunzima ngakumbi kunolo lwevalve yombane. Kwaye ixabiso libiza kakhulu, ukuba libandakanya ulawulo oluzenzekelayo, kuyimfuneko yokongeza i-valve ye-electromagnetic reversing valve, kunye ne-agility ye-electromagnetic reversing valve ichaphazela ngqo i-valve ye-pneumatic. Ndikhetha umgangatho wokuqala.

Iivalvu zombane zingasetyenziswa ukuba nje umbane ukhona. Kwezinye iifektri, izixhobo ezininzi kunye nezixhobo zisebenzisa umoya oxinanisiweyo. Kule meko, iivalve ze-pneumatic zingasetyenziselwa, ekubeni zifumaneka ngokukhawuleza. Impendulo ikhawuleza, ikhuselekile kwaye inokwethenjelwa, iifektri ezininzi ezineemfuno zolawulo oluphezulu zenzelwe izinto zokulawula isixhobo sepneumatic ukuseta isikhululo somoya esicinezelekileyo. Umbane uthetha umbane. Ivalve ye-pneumatic ingcono kakhulu kunevalve yombane, kodwa umthombo womoya umbi kangangokuba ivalve yombane isetyenziswa kwindawo yomthombo womoya.
