Imihlahlandlela Yokukhetha I-Valve Nokubuyisela Imikhuba Emihle

Ukubaluleka kokukhetha ama-valve: Ukukhethwa kwezakhiwo zamavalvu okulawula kunqunywa ngokucubungulisisa izici ezifana nendawo esetshenziswayo, izinga lokushisa, izingcindezi ezikhuphuka nomfula kanye nezansi nomfula, izinga lokugeleza, izici ezibonakalayo namakhemikhali aphakathi nendawo, kanye nokuhlanzeka kwendawo ephakathi nendawo. Ukunemba kanye nokuhluzeka kokukhethwa kwesakhiwo se-valve kuthinta ngokuqondile ukusebenza, amandla okulawula, ukuzinza kokulawula, kanye nempilo yesevisi.

I. Amapharamitha okucubungula:

1. Okumaphakathi'sIgama.
2. Ukuminyana okumaphakathi, i-viscosity, izinga lokushisa, nokuhlanzeka kwendawo emaphakathi (enezinhlayiya).
3. Izici Ze-Physicochemical Ezimaphakathi: Ukugqwala, Ubuthi, kanye ne-pH.
4. Amazinga Okugeleza Okumaphakathi: Okukhulu, Okujwayelekile, Nokuncane
5. Ingcindezi eya phezulu naphansi kweValve: Okuphezulu, Okujwayelekile, Okuncane.
6. I-viscosity emaphakathi: ukuphakama kwe-viscosity, kuthinta kakhulu ukubalwa kwevelu ye-Cv.

Lawa mapharamitha asetshenziswa kakhulu ukubala ububanzi be-valve edingekayo, inani le-Cv elilinganiselwe, namanye amapharamitha anobukhulu, kanye nokunquma izinto ezifanele okufanele zisetshenziselwe i-valve.

II. Amapharamitha asebenzayo:

1. Izindlela zokusebenza: ugesi, i-pneumatic,i-elector-hydraulic, i-hydraulic.
2. Ivalvu'simisebenzi: ukulawula, ukuvala, kanye nomthethonqubo ohlangene&vala.
3. Izindlela zokulawula:Umfakisicelo, i-valve ye-solenoid, i-valve yokunciphisa ingcindezi.
4. Imfuneko yesikhathi sokwenza.

Le ngxenye yemingcele isetshenziselwa ikakhulukazi ukunquma ezinye izinto ezisizayo ezidinga ukulungiswa ukuze zihlangabezane nezidingo zokusebenza ze-valve.

III. Amapharamitha wokuvikela angaqhumi:

1. Isilinganiso sokuvikela ukuqhuma.
2. Izinga lokuvikela.

IV. Uhlu Lwezinhlaka Zemvelo Nezinamandla

1. Izinga lokushisa le-ambient.
2. Imingcele yamandla: ingcindezi yokunikezwa komoya, ingcindezi yokunikezwa kwamandla.

Izinyathelo Zokuqaphela Ukushintsha Ama-valve

Ukuqinisekisa ukushintshwa kwama-valve okuhambisanayo futhi uvimbele izinkinga zokufakwa, sicela unikeze izilinganiso ezilandelayo. Ukwehluka phakathi kwabakhiqizi kanye nemiklamo kungaholela ekulinganisweni okubi noma indawo enganele. NgoI-TWS, ochwepheshe bethu bazolungisa isisombululo ngokuncoma i-valve efanele—uvemvane valve, i-valve yesango, nomahlola i-valve- ngokwezidingo zakho, isiqinisekiso sokusebenza nokuqina.
