Valve ukulawula uhlobo valve okuyinto uthola isicelo yasakazwa kulezo zimboni. Le divayisi ingasetshenziswa njengendlela lokushisa isilawuli elula noma njengengxenye Inqubo elawula uhlelo e imodi othomathikhi. Kungakhathaliseki lezi zici, iphuzu elibaluleke kakhulu iyona ukukhethwa valve.
Uma valve ukulawula ukhethwa ngendlela efanele, lokhu kuzoqinisekisa hhayi kuphela elilungile ukulawula ukunemba, kodwa futhi kulula ukuze sigweme izinkinga ezifana ukuguguleka komhlabathi kanye okusezingeni eliphezulu umsindo ezingeni. Kwezinye izimo, valve has a -bandwidth okuhambisana ngokugcwele umsebenzi owenziwayo, futhi ukuze kuncishiswe kunomsindo kufanele izinhlobo ukuqinisa kokuba emikhulu enobubanzi obungu ayethanda.
Valve ukulawula kunzima ngempela eyolanda ngenxa yokuthi ukuthi adingekile ukuze uxhumanise eziningi izidingo ukuthi, eqinisweni, kukhona alizimele. Ukukhethwa INGAPHANDLE ephansi bandwidth noma amasheya ayo isivuno sisiningi kakhulu khona kungase kube imbangela yezinkinga abalulekile. Uma valve ukulawula has a-bandwidth likhulu kakhulu, lokhu kuholela ekutheni ukuthi alinikezi ezingeni elifanele lokulawula ukunemba. Lokhu kungenxa yokuthi i-stem umphini izoya ibanga elincane (obunganakekile njengoba kuqhathaniswa ngemivimbo ngokugcwele). amaphutha okunjalo ngokuvamile kwenza ukuntengantenga lonke uhlelo, kanye ukwehluleka kokubili valve futhi yonke drive. Ngezinye izikhathi valve ukulawula kuyakhethwa ukuze iconsi ingcindezi yonkana Idivayisi esiphezulu evulekile ngale nkinga ethile enkulu umusi ukugeleza rate. Uma sikhuluma practice, lokhu kusho ukuthi ukukhethwa wenziwa phezu iconsi valve ingcindezi.
Kuvele ipharamitha ezibalulekile okudinga ukuqondiswa uma kukhethwa valve elawula, umsindo. Valve Kufanele kukhethwe ukuze Isivinini qeda of umusi kwayo kuleyo ndawo yokuhweba ingeqi 30% ijubane umsindo. Lokhu ipharamitha ngokuvamile kudlulwe ngenxa yokuthi ukuthi enobubanzi obungu-valve lincane kakhulu, futhi lapho isihlalo sehhashi sinesikhundla eside. Shut-off futhi elawula umphini ungaba umklamo ekhethekile evumela ukunciphisa kakhulu kunomsindo. Amayunithi ezinjalo yebhangqa sehhashi-plug amelwe ngesimo isilinda perforated, okuyinto kakhulu kunciphisa umsindo cavitation Inciphisa (lapho valve asetshenziswa ketshezi).
Ukukhetha Valve, kwaba sobala, kumele kwenziwe nge obligatory akhawunti isethi eside yezinto, okuyinto kakhulu inkimbinkimbi inqubo. Indlela engcono ukugwema ezinye izinkinga ukuphendukela umhlinzeki omethembayo, engenalo ulwazi olwanele kanye nesipiliyoni. Lokhu kuzokuvumela ukuba anikele iklayenti imikhiqizo esiphezulu izinga. Kubalulekile ukuba banake amaphuzu athile, phakathi lapho umi phandle: idumela umenzi, nokufaneleka valve iyokhandwa, kungenzeka zishintsheke amandla noma ukwenziwa valve, kanye neminye imingcele ezithinta Ukusebenziseka.
