Ivalve yeSolenoididlala indima ekulungiseni isalathiso, ukuhamba, isantya kunye nezinye iiparameters ze-medium kwi-industrial control system. Nangona iyinto encinci, inolwazi oluninzi. Namhlanje, siya kuququzelela inqaku malunga nomgaqo-siseko walo, ukuhlelwa kunye nokusetyenziswa. Masiyifunde kunye.
Umgaqo woLwakhiwo
Le mveliso ubukhulu becala yenziwe ngumzimba wevalvu, indawo yokungenisa umoya, indawo yokuphuma komoya, ucingo olukhokelayo kunye neplunger, kwaye umgaqo wayo wokusebenza unokwaziwa kwisakhiwo sayo.
Xa imveliso ingafakwanga umbane, inaliti yevalve iya kuvala indlela yokudlulaumzimba wevalvuphantsi kwesenzo sentwasahlobo, ukwenzela ukuba imveliso ibe kwimeko yokunqunyulwa. Xa ikhoyili iqhagamshelwe kunikezelo lwamandla, ikhoyili iya kuvelisa amandla kazibuthe, kwaye undoqo wevalve unokoyisa amandla entwasahlobo kwaye uphakamisele phezulu, ukuze umjelo okwivalve uvule kwaye imveliso ikwimeko yokuqhuba.
Abasebenzi abahlela iimveliso banokwahlulwa ngokweendidi ezintathu: ukusebenza ngokuthe ngqo, ukunyathela ngokuthe ngqo kunye ne-pilot-acting, kwaye inokwahlulwa ibe yi-diaphragm esebenza ngokuthe ngqo, isakhiwo se-diaphragm isinyathelo-by-step, i-pilot diaphragm. Ulwakhiwo, ulwakhiwo lwepiston olusebenza ngokuthe ngqo, ubume bepiston ngamanyathelo kunye nolwakhiwo lwepiston yepiston ngokwesakhiwo kunye nemathiriyeli
ivalveidiski.
Ukulumkela
Xa sisebenzisa imveliso yokulinga, kufuneka sinikele ingqalelo ukuba umahluko woxinzelelo lwangaphakathi kumbhobho wanele. Ukuba umehluko woxinzelelo uncinci kwaye umkhiqizo awukwazi ukusebenza ngokuqhelekileyo, iimveliso ezisebenza ngokuthe ngqo zingakhethwa. Umahluko woxinzelelo mkhulu kakhulu, ngoko kufuneka ukhethe iimveliso ezinoxinzelelo oluphezulu. Okwesibini, iimveliso eziqhelekileyo zifakwe ngokuthe tye, kungekhona kuphela kwicala, kodwa nakwicala, elinokuthi libangele ukuba i-valve ivalwe ngokukhululekileyo kwaye ibangele ukuvuza kwangaphakathi. Okwesithathu, xa isetyenziswa ngokuqhubekayo ixesha elide, kuyimfuneko ukuqinisekisa ukuba isitywina phakathi kwepiston kunye nesihlalo sevalve silungile. Nje ukuba itywina libe libi kakhulu, indawo yokutywina yepiston kunye nesihlalo sevalvu inokuphinda ibekwe phantsi. Okwesine, soloko ubeke ingqalelo kwii-gauges zoxinzelelo ngaphambi nangemva kwevalve ukuqinisekisa ukuba uxinzelelo olusebenzayo kunye nokwahlukana kwengcinezelo yokusebenza kungaphakathi koxinzelelo olulinganisiweyo kunye nomlinganiselo woxinzelelo olulinganisiweyo, kwaye uyeke ukusebenzisa imveliso ukuba kufunyaniswe ukuba uxinzelelo olusebenzayo kunye noxinzelelo lokusebenza. Umahluko ugqithise ixabiso elichaziweyo.
