Yiziphi izimo zokukhetha ivalvu yebhabhathane kagesi kanye nevalvu yebhabhathane ephefumula umoya?

Izinzuzo kanye nokusetshenziswa kweamavalvu ebhabhathane kagesi

Ugesiivalvu yebhabhathaneiyithuluzi elivame kakhulu lokulawula ukugeleza kwamapayipi, elinokusetshenziswa okubanzi futhi elihilela izinkambu eziningi, njengokulawula ukugeleza kwamanzi edamini lendawo yokugcina amanzi esiteshini samandla kagesi, ukulawula ukugeleza koketshezi lwezimboni efektri, njll., futhi okulandelayo kuzokuqondisa ekuqondeni izici, izinzuzo kanye nokusetshenziswa kwevalvu yebhabhathane kagesi.

1. Ukuvala okuhle

Phela, indima kagesiivalvu yebhabhathaneisetshenziselwa ukulungisa ukugeleza koketshezi ngesikhathi, futhi ibhekene nokushisa okuphezulu kanye nokucindezela okuphezulu lapho isebenza, ngakho-ke uma ukuvala kungalungile, kuzoholela ekuvuzeni koketshezi, futhi akunakwenzeka ukuqinisekisa ukulungiswa okunembile kokugeleza. Ugesiivalvu yebhabhathaneinesistimu yokuvala ekhethekile, ngakho-ke inokuvala okuhle kusukela ekushiseni okuphansi kakhulu kuya ekushiseni okuphezulu, okungukuthi, ukuvala ivalvu yebhabhathane kagesi akuthinteki yizinga lokushisa, futhi inkinobho yevalvu yokulungisa kagesi ilula kakhulu.

2. Akukho ukuvuza

Okutusekayo kakhulu ukuqina kukagesiivalvu yebhabhathane, uphawu lobubanzi bomgodi wesiqu se-valve luthatha indandatho evalwe kakhulu, indandatho yokuvala icindezelwa yi-graphite, indandatho yokuvala kanye nepuleti le-butterfly le-valve ye-butterfly kagesi ngeke inamathele, ngakho-ke ukuvala kuhle impela, i-valve ye-butterfly kagesi yokuphepha komlilo engavuzi lutho iyindlela ekhethwa ngamakhasimende amaningi.

3. Ukulungiswa okulula nokulawula

Ugesiivalvu yebhabhathaneiyithuluzi elisetshenziselwa ukulawula ukugeleza koketshezi, ngaphezu kokuthutha nokulawula uketshezi, udaka nezinye izinto ezine-viscosity ethile nazo zingathuthwa, futhi uketshezi oluqongelelwe epayipini luncane, futhi ukuvulwa nokuvalwa kukagesi kuyashesha futhi kulula.

Kunezinhlobo eziningi zamavalvu asetshenziswa embonini, kodwa kudinga umzamo omkhulu ukuthenga ivalvu egculisayo ngempela, kagesiivalvu yebhabhathaneinezinhlobo eziningi zezicelo, ukusebenza kahle kanye nokuvala okuhle kakhulu, futhi uhlobo lwevalvu kagesi yezimboni esetshenziswa kabanzi.

Izinzuzo kanye nokusetshenziswa kwamavalvu ebhabhathane asebenzisa umoya

I-valve ye-pneumatic butterfly yakhiwe yi-actuator ye-pneumatic kanye ne-valve ye-butterfly. I-valve ye-pneumatic butterfly iyi-valve ye-pneumatic esebenzisa ipuleti le-butterfly eliyindilinga elijikeleza nesiqu se-valve ukuvula nokuvala ukuze kufezwe isenzo esivumelayo, ikakhulukazi esetshenziswa njenge-valve yokuvala, futhi ingaklanywa futhi ibe nomsebenzi wokulungisa noma i-valve yesigaba nokulungisa, futhi i-valve ye-butterfly isetshenziswa kakhulu emipayipini emikhulu nephakathi enomfutho ophansi. Ukuhlukaniswa kwe-valve ye-butterfly ye-pneumatic: i-valve ye-butterfly yensimbi engagqwali, i-valve ye-butterfly ye-pneumatic ye-hard seal, i-valve ye-butterfly ye-pneumatic ye-soft seal, i-valve ye-butterfly ye-carbon steel pneumatic. Izinzuzo eziyinhloko ze-valve ye-butterfly ye-pneumatic, isakhiwo esilula, usayizi omncane, isisindo esincane, izindleko eziphansi, i-valve ye-butterfly ye-pneumatic ibaluleke kakhulu, ifakwe esiteshini esimnyama esiphakeme, kulula ukuyisebenzisa ngokulawula i-valve ye-solenoid enezindawo ezimbili, futhi ingalungisa ne-flow medium.

Kunezinye izici okudingeka zicatshangelwe ohlelweni lwempuphu lwevalvu yebhabhathane ephefumulayo, njengokuthi: impahla ayikwazi ukuphuthunyiswa ngqo epuletini yevalvu yevalvu uma ifakwa enqoleni isuka phezulu (la mandla okushaya azokwenza futhi ivalvu ingakwazi ukuvala kahle), futhi ingcindezi engaguquki yezinto akufanele idlule ingcindezi yomklamo wevalvu yebhabhathane ephefumulayo, njll.

Umehluko phakathi kwevalvu yokulawula kanye nevalvu evamile yesandla ukuthi ayikwazi ukubhekwa njengengxenye ehlukanisiwe, kodwa kumele ibhekwe njengengxenye yesistimu yokulawula ezenzakalelayo, izinkinga eziningi ekusetshenzisweni kwevalvu yokulawula akuyona inkinga yokukhetha nokucushwa, kodwa ngenxa yokuthi ukuqonda komsebenzisi ngevalvu yokulawula akwanele, ivalvu yokulawula ayikalungiswa futhi ayihlanganiswanga nesistimu yokulawula. Uma nje siqaphela isihluthulelo senkinga, sikhetha ivalvu ngendlela efanele, futhi silungisa ivalvu yokulawula esigabeni sokulungisa amaphutha ohlelweni, singanciphisa kakhulu izinga lokuhluleka futhi senze uhlelo lokulawula oluzenzakalelayo lusebenze kahle isikhathi eside.
