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

Izinzuzo kanye nokusetshenziswa kukagesiamavalvu ebhabhathane

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. Ivalvu yevemvane kagesi inohlelo lokuvala olukhethekile, ngakho-ke inokuvala okuhle kusukela ekushiseni okuphansi kakhulu kuya ekushiseni okuphezulu, okungukuthi, ukuvala ivalvu yevemvane kagesi akuthinteki ukushisa, futhi inkinobho yevalvu yokulungisa kagesi ilula kakhulu.

2. Akukho ukuvuza

Okutusekayo kakhulu ukuqina kwe-ivalvu yebhabhathane kagesi, 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 ze-amavalvuisetshenziswa embonini, kodwa kudinga umzamo omkhulu ukuthenga ivalvu eyanelisa ngempela, ivalvu yebhabhathane kagesi inezinhlobo eziningi zezicelo, ukusebenza kwayo okuqinile kanye nokuvala okuhle kakhulu, futhi iwuhlobo lwevalvu kagesi yezimboni esetshenziswa kabanzi.

Izinzuzo kanye nokusetshenziswa kwe-pneumaticamavalvu ebhabhathane

I-valve yebhabhathane ephefumula umoya yakhiwe yi-actuator yomoya kanye ne-ivalvu yebhabhathane. I-valve yebhabhathane yomoyaiyivalvu yomoya esebenzisa ipuleti levemvane eliyindilinga elijikeleza nesiqu sevalvu ukuvula nokuvala ukuze kufezwe isenzo esivumelayo, ikakhulukazi esetshenziswa njengevalvu yokuvala, futhi ingaklanywa futhi ibe nomsebenzi wokulungisa noma ivalvu yesigaba nokulungisa, futhi ivalvu yevemvane isetshenziswa kakhulu emipayipini emikhulu nephakathi enomfutho ophansi. Ukuhlukaniswa kwevalvu yevemvane yomoya: ivalvu yevemvane yomoya yensimbi engagqwali, ivalvu yevemvane yomoya eqinile, ivalvu yevemvane yomoya ethambile, i-carbon steel pneumaticivalvu yebhabhathaneIzinzuzo eziyinhloko zevalvu yebhabhathane ephefumulayo, isakhiwo esilula, usayizi omncane, isisindo esilula, izindleko eziphansi, ivalvu yebhabhathane ephefumulayo ibaluleke kakhulu, ifakwe esiteshini esimnyama esiphakeme, kulula ukuyisebenzisa ngokulawula ivalvu ye-solenoid enezindawo ezimbili, futhi ingalungisa nendawo yokugeleza.

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.
