Uyini umehluko phakathi kwevalvu ye-SDV nevalvu yokuphepha?

Kunomehluko omkhulu phakathi kwama-valve e-SDV (ama-valve okuvala) nama-valve okuphepha maqondana nomsebenzi, isimiso sokusebenza kanye nezimo zokusetshenziswa. Okulandelayo ukuhlaziywa okuningiliziwe komehluko phakathi kwama-valve amabili:

Okokuqala, umehluko wokusebenza

Ivalvu ye-SDV (ivalvu enqunyiwe):

Umsebenzi oyinhloko ukunqamula nokulawula ukugeleza koketshezi. Uma kuvela isimo esiphuthumayo, ivalvu ye-SDV inganqamula ngokushesha ukugeleza kwemidiya, ivimbele ukwanda kwezingozi, futhi iqinisekise ukuphepha kwabasebenzi nemishini.

Ivalvu yokuphepha:

Umsebenzi oyinhloko ukuvimbela umonakalo wemishini noma wepayipi ngenxa yokucindezela ngokweqile. Lapho ingcindezi ephakathi emishinini noma epayipini idlula inani elibekiwe, ivalvu yokuphepha ivuleka ngokuzenzakalelayo, futhi ingcindezi iyancipha ngokukhipha i-medium ngaphandle kwesistimu, ngaleyo ndlela kuvikelwe ukuphepha kwemishini kanye nepayipi.

Okwesibili, umehluko ezimisweni zokusebenza

Ivalvu ye-SDV (ivalvu enqunyiwe):

Isimiso sokusebenza sisekelwe kuma-actuator omoya. Ngemva kokuthola isignali yokulawula, i-solenoid valve ilawula ukuvulwa komthombo womoya ocindezelwe, ngaleyo ndlela iqhube ukuvulwa noma ukuvalwa kwe-valve. Ama-valve e-SDV avuleka ngokuphelele futhi avalwe ngokuphelele, ngakho-ke aziwa nangokuthi ama-valve anezikhundla ezimbili.

Ivalvu yokuphepha:

Isimiso sokusebenza sisekelwe emandleni esiphethu noma isisindo. Lapho ingcindezi ephakathi idlula inani elibekiwe, isiphethu noma isisindo siyacindezelwa noma siyathuthwa, ngaleyo ndlela sivule ivalvu ukuze kukhishwe ingcindezi. Lapho ingcindezi yehliswa ibe inani elibekiwe, isiphethu noma isisindo siyalulama bese ivalvu ivala ngokuzenzakalelayo.

Okwesithathu, umehluko ezimweni zohlelo lokusebenza

Ivalvu ye-SDV (ivalvu enqunyiwe):

Isetshenziswa kabanzi embonini yamakhemikhali kaphethiloli, yezemithi, yokudla, yokwakha imikhumbi kanye neminye, kanye nasezinkundleni zikawoyela zasogwini. Ifaneleka kakhulu ezimweni lapho ukugeleza kwemidiya kudinga ukunqanyulwa ngokushesha ukuze kuvikelwe imishini nezinhlelo.

Ivalvu yokuphepha:

Isetshenziswa kakhulu kuma-boiler, imikhumbi yokucindezela, izinhlelo zamapayipi kanye neminye imishini ukuvimbela umonakalo wemishini kanye nezingozi zokuphepha ezibangelwa ukucindezela ngokweqile. Ama-valve okuphepha avame ukusetshenziswa kuma-boiler omusi, ithangi legesi likaphethiloli elinoketshezi noma izimoto zamathangi esitimela segesi likaphethiloli elinoketshezi, i-production Wells, imishini yokukhiqiza ugesi womusi edlula ngomfutho ophezulu kanye nezinye izikhathi.

Okwesine, eminye imehluko

Izici zesakhiwo:

Isakhiwo sevalvu ye-SDV (ivalvu enqunyiwe) silula kakhulu, ngokuvamile sihlanganisa izingxenye ezimbili ze-actuator kanye nomzimba wevalvu. I-actuator ingaba yi-pneumatic, kagesi noma i-hydraulic, njll., futhi umzimba wevalvu ungakhethwa ngokuya ngezici ze-medium kanye nezidingo zokusetshenziswa.

Isakhiwo sevalvu yokuphepha siyinkimbinkimbi kakhulu, ngokuvamile sihlanganisa umzimba, isihlalo, idiski yevalvu, intwasahlobo noma isisindo kanye nezinye izingxenye. Izinhlobo ezahlukene zesakhiwo samavalvu okuphepha (njengohlobo lwentwasahlobo, uhlobo lwesisindo se-lever, uhlobo lwe-pulse, njll.) zinezici ezahlukene kanye nobubanzi bokusetshenziswa.

Izidingo zokusebenza:

Izidingo zokusebenza kwevalvu ye-SDV (ivalvu enqunyiwe) zifaka phakathi ukusebenza kokuvala, isivinini sokuvula nokuvala, impilo yesevisi njalo njalo. Ekukhetheni, kuyadingeka ukukhetha ngokuya ngezimo zokusebenza zangempela kanye nezici zemidiya.

Izidingo zokusebenza kwevalvu yokuphepha ziqinile kakhulu, ngaphezu kokusebenza kokuvala okuyisisekelo kanye nesivinini sokuvula nokuvala, kodwa futhi kudingeka kucatshangelwe umthamo wokukhipha, ingcindezi yokubuyisa, umehluko wengcindezi yokuvula nokuvala kanye nezinye izinkomba ezibalulekile. Lezi zinkomba zithinta ngqo umphumela wokuvikela wevalvu yokuphepha kanye nokusebenza okuphephile kohlelo.

Ngamafuphi, kunomehluko omkhulu phakathi kwama-valve e-SDV (ama-valve anqunyiwe) nama-valve okuphepha maqondana nomsebenzi, isimiso sokusebenza, izimo zokusetshenziswa kanye nezici zesakhiwo. Ukukhetha kudinga ukucatshangelwa ngokuphelele ngokwezidingo zangempela zokusetshenziswa kanye nezimo zokusebenza.
