Izinkinga ezivamile zevalvu kagesi zikufundisa ukukhetha okunembile kwe-valve kagesi kanye ne-pneumatic valve kanye nezinzuzo kanye nokubi kwezinhlobo ezimbili zamavalvu.

Umthelela wesikali

Kungakhathaliseki ukuthi i-valve ye-solenoid noma i-valve kagesi, isikali ngeke sibangele ukuvuza kwe-valve kuphela, okunamandla ngisho nokuthinta umsebenzi ojwayelekile we-valve, ngakho-ke indlela yokuqeda umthelela wesilinganiso, sekuyinkinga evamile embonini.

Umsebenzi we-valve wokulawula awulungile

Inqubo ye-valve ye-Solenoid yokubandakanya ububanzi ibanzi kakhulu, kodwa ngenxa yokuthi ukwakheka kwe-actuator kanye nokusetshenziswa kwezinto zokugcwalisa okubangelwa umsebenzi ompofu we-valve yokulawula kusengafingqwa imithetho yayo.

Ukuba khona kwezindawo ezifile enqubweni kuzobangela ukuguquguquka kwenqubo ukuthi kuphambuke endaweni ebekiwe yokuqala. Ngakho-ke okukhiphayo kwesilawuli kufanele kukhuliswe ngokwanele ukuze kunqobe indawo efile ukuze kwenzeke lesi senzo sokulungisa.

Izici eziyinhloko ezithinta indawo efile:

① Ifriction, drift, valve shaft torsion, amplifier dead zone. Ama-valve okulawula azwela ukungqubuzana ngezindlela ezahlukene. Ama-valve ajikelezayo, isibonelo, azwela ukungqubuzana okubangelwa ukugcwala kwezihlalo eziphezulu, ngakho qaphela lokhu uma usebenzisa. Kwezinye izimpawu, nokho, umthwalo wesihlalo esiphezulu uyadingeka ukuze kuzuzwe isigaba sezimpawu. Ngenxa yalokho, i-valve yakhelwe kabi futhi ibangela kalula indawo enkulu efile, enomthelela osobala futhi ocishe unqume izinga lokuchezuka kwenqubo.

② Ukuguga. Ukugqokwa kwe-valve akunakugwenywa ekusetshenzisweni okuvamile, kodwa ukuguga kwesendlalelo sokuthambisa kubi kakhulu, ngokobufakazi bokuhlola, i-valve ejikelezayo yokugcoba kuphela ngamakhulu okuphindukuzalwa kwesenzo, isendlalelo sokuthambisa singasetshenziswa kancane. Ngaphezu kwalokho, umthwalo obangelwa ukucindezela ungase uholele ekugqokeni kwezimpawu, okuyisici esiyinhloko ekwandiseni ukungqubuzana. Umphumela uba i-valve yokulawula ebhubhisayo

(3) Ukungqubuzana kokupakisha kuwumthombo oyinhloko wokungqubuzana kwe-valve yokulawula, ukusetshenziswa kokupakisha okuhlukile, okuholela ekuhlukeni okukhulu kokungqubuzana.

(4) Izinhlobo ezihlukene zama-actuator nazo zinomthelela obalulekile kumandla okushayisana. Ngokuvamile, ama-actuator amafilimu asentwasahlobo angcono kune-piston actuators.

Zifundise ukukhetha okunembile kwe-valve kagesi kanye ne-pneumatic valve kanye nezinzuzo kanye nokubi kwezinhlobo ezimbili zama-valve I-valve kagesi eqhutshwa ugesi, ezidingweni zokuvikela ukuqhuma kwesenzakalo ayifaneleki, njengendawo eseduze enenombolo enkulu kalula. igesi edayiwe, ungathembela kuphela kumoya womoya. Isikhathi sokuphendula somoya sihamba kancane kunesikagesi, asinembile njengogesi, i-valve yomoya ingamandla omoya. I-valve kagesi iguqulwa ibe amandla kagesi njengamandla, i-agility ye-valve kagesi iphakeme kunaleyo ye-valve ye-pneumatic, ukuphepha nokuthembeka akunamandla njenge-valve ye-pneumatic, ukugcinwa akulula njenge-valve yomoya. , amandla awanamandla njenge-valve ye-pneumatic.

1. Ivalvu kagesi isebenzisa injini njengamandla, futhi ivalvu yomoya isebenzisa umoya ocindezelwe njengamandla.

1. Izinzuzo zevalvu kagesi: Umphumela omuhle kugesi owuketshezi ophakathi nendawo nobubanzi obukhulu, ongathinteki esimweni sezulu. Akuthintwa umfutho womoya.

Ukungalungi: izindleko eziphezulu, hhayi ezinhle endaweni enomswakama.

2. Izinzuzo ze-valve ye-pneumatic: Umphumela omuhle kuketshezi oluphakathi kwegesi nobubanzi obuncane, izindleko eziphansi kanye nokugcinwa kalula.

Ukungalungi: Kuthintwa ukuguquguquka komfutho womoya, kulula ukuthintwa umfutho womoya namanzi omoya ebusika obusenyakatho, okuholela emakhazeni futhi kungabikho mnyakazo womnyango wokudlulisa.

Indlela yokukhetha i-valve kagesi ne-pneumatic valve ngokunembile

Okwesibili, i-pneumatic jikelele iyashesha ukwedlula ugesi, ugesi uwukusebenzisa okukabili ithoshi. Futhi i-pneumatic to hand, intengo yokusetshenziswa kwegesi kabili iphezulu uma kuqhathaniswa.

Okwesithathu, i-valve kagesi isetshenziswa kwezinye izindawo ezinobubanzi obukhulu, ngoba i-pneumatic inzima ukuyenza, kodwa i-valve kagesi ayiyona isiphithiphithi njenge-pneumatic, isivinini sokushintsha sihamba kancane, i-actuator izobanjelwa isikhathi eside. I-valve ye-pneumatic switch ngokushesha, ukunemba okuphezulu, kodwa ayidingi isiphithiphithi somthombo womoya.

Okwesine, i-valve kagesi isinyathelo kancane valve kagesi angenza brand ukuqhuma-ubufakazi akuyona eziningi; Isenzo sevalvu yomoya siyashesha, inani elihlobene nokuvikela ukuqhuma kunezansi kagesi (ihabhu le-valve yomoya enaziphi izesekeli, ezinezesekeli zomkhiqizo omkhulu zizobiza kakhulu kunevalvu kagesi).

Ama-valve ahilelekile ekuxhumaneni nawo asebenza ngogesi. Kungani?

1, ngokusho kwesimo sezulu sendawo, uma isimo sezulu simanzi, i-valve ye-pneumatic ayikwazi ukusetshenziswa, ngoba umthombo womoya unamanzi.

I-2, i-valve kagesi ingakwazi futhi ukubona umsebenzi wokuxhuma ngaphandle kokunyuka okwengeziwe kokusetshenziswa, ukuxhuma kwe-pneumatic kuzokwandisa i-valve yokugcina, kwandise izindleko.

Izinzuzo kanye nokubi kwe-valve kagesi kanye ne-pneumatic valve:

Ngaphansi kwaziphi izimo okudingeka usebenzise i-valve kagesi ngaphandle kwe-pneumatic, lapho isidingo sokusebenzisa i-pneumatic ngaphandle kwe-valve kagesi, phakathi kwabo yiziphi izinzuzo nezingozi, intengo. Ibanga lesenzo se-valve ye-pneumatic likhulu kune-valve kagesi, isivinini sokushintshwa kwe-valve ye-pneumatic singashintshwa, isakhiwo esilula, kulula ukusigcina, ngesikhathi sesenzo ngenxa yezimpawu ze-buffer zegesi ngokwayo, akulula ukulinyazwa i-jamming, kodwa kufanele ibe nomthombo womoya, futhi uhlelo lwayo lokulawula luyinkimbinkimbi kune-valve kagesi.

I-valve kagesi iqhutshwa ugesi, ongafanele umcimbi wezidingo zokuvimbela ukuqhuma. Uma inani elikhulu lamagesi adaywe kalula lihlakazwa endaweni eseduze, lingathembela kuphela kumoya womoya. Isikhathi sokuphendula somoya sihamba kancane kunesikagesi, asinembile njengogesi, i-valve yomoya ingamandla omoya. I-valve kagesi iguqulwa ibe amandla kagesi njengamandla, i-agility ye-valve kagesi iphakeme kunaleyo ye-valve ye-pneumatic, ukuphepha nokuthembeka akunamandla njenge-valve ye-pneumatic, ukugcinwa akulula njenge-valve yomoya. , amandla awanamandla njenge-valve ye-pneumatic.

Ukulawulwa kwe-valve ye-pneumatic kuyinkimbinkimbi kakhulu kunaleyo ye-valve kagesi. Futhi izindleko zibiza kakhulu, uma kuhilela ukulawula okuzenzakalelayo, kuyadingeka ukwengeza i-valve yokuhlehlisa i-electromagnetic, futhi i-agility ye-electromagnetic reversing valve ithinta ngokuqondile i-valve ye-pneumatic. Ngincamela isitezi sokuqala.

Amavalvu kagesi angasetshenziswa inqobo nje uma ugesi ukhona. Kwamanye amafekthri, amathuluzi amaningi nemishini kusebenzisa umoya ocindezelweyo. Kulokhu, ama-valve we-pneumatic angasetshenziswa, ngoba atholakala kalula. Impendulo iyashesha, iphephile futhi inokwethenjelwa, izimboni eziningi ezinezidingo zokulawula eziphezulu zenzelwe izinto zokulawula insimbi yomoya ukuze kumiswe isiteshi somoya esicindezelwe. Ugesi usho ugesi. I-valve ye-pneumatic ingcono kakhulu kune-valve kagesi, kodwa umthombo womoya mubi kangangokuthi i-valve kagesi isetshenziswa endaweni yomthombo womoya.
