Uphi i-valve yokunciphisa i-valve esetyenziswayo?

Kwiinkqubo zoxinzelelo lwamanzi zorhwebo, izixhobo ezifana nezigwityu zokulawula, izicwangciso zokulawula uxinzelelo, kunye nezinye iipavvesti ze-throttle zivame ukusetyenziswa njengezixhobo zokulawula uxinzelelo. Abalawuli abahlukileyo, abanye balawula uxinzelelo emva kwabo, abanye-ngokwabo. Umxinzelelo wokunciphisa i-valve yamanzi uthathwa njengomlawuli osebenza ngokuthe ngqo. Ulawula uxinzelelo emva kwakhe, kodwa kwimeko yokuba le ngcinezelo ingaphantsi kwehafu yesigqibo.

Impawu zendlela

Umxinzelelo wokunciphisa i-valve ilawulwa ngumthombo wamanzi ohamba ngebhodi yokusebenza ngokuhambisa isisombululo esilawulayo ngenxa yamandla okubangelwa utshintsho olushintshayo kwi-index.

Ulwakhiwo, i-valve yokunciphisa iqukethe izinto ezintathu eziphambili: iqumrhu elilawulayo, i-e. Iiplati, i-reference element, okanye intwasahlobo, kunye nesalathiso sokubhaliweyo, esiyimbumba.

Umgaqo we-valve ngumququzelelo we-medium medium. Amanzi avela kwisigxina esiphezulu sogxobhozo ukuya kumgangatho ophantsi wexinzelelo, okwaziswa ngegap phakathi kwesihlalo kunye ne-disc valve. Inxalenye ethintekayo isoloko i-soft rubber membrane kunye ne-gaskets emibili, kodwa kwezinye iimodeli ingaba i-piston eneebhokhwe zokutywinwa okanye iindandatho ezenziwe ngempahla yerubha. Njengendlela yokukhiya, iiplati ezenziwe ngeeribha ezixutywayo kunye ne-alloy metal.

Ukukhethwa kweValve

Isicatshulwa ngasinye sokunciphisa i-valve sikhethwe ngokusekelwe kwixabiso le-Kvs (ukugqithiswa kwamagatya eepayipi). Phakathi kwezinye iimpawu zezobugcisa zazo zonke iipavus zokunciphisa uxinzelelo, ixabiso eliphezulu leKvs kufuneka liboniswe kuwo onke amanani alinganayo.

I-valve yokunciphisa uxinzelelo ikhethiweyo ukwenzela ukuba isantya esiphezulu esifanelekileyo siphakathi kwexabiso elincinci nelikhulu. Ukuze ukhethe ubungakanani obukhulu, iimveliso zihlolwe ngokubhekiselele kwietafile zamanani eyaziwayo ekuphumeni kweevini. Nangona kunjalo, kwiintlobo ezithile zeepavini, amandla okukhupha awanakuxhomekeka kumgama othethiweyo (njengokuba kukho ubukhulu be-DM505, iDM510-518). Kunqabile kakhulu ukusetyenziswa ukuqiniswa kunye nobukhulu bomlinganiselo obuncinane bobuncinci obuncinane kunomlinganiselo wokusebenza wepayipi.

Izicwangciso zokunciphisa izicwangciso zeValve

Ukuchaneka okuphezulu kwimiba yokucwangcisa uxinzelelo kwintlobo kunokufezwa ngokukhawulelana nenqanaba lokumisela uxinzelelo olusondeleyo ngokubanzi kunokwenzeka kwinqanaba elingaphezulu. Ukuba uxinzelelo lwe-outlet oyifunayo, umzekelo, i-2.3 bar, ngoko udidi kufuneka lube kwibanga le-0.8 ukuya kwe-2.5 kwibha, kungekhona yonke ibha ye-2-5. Ukuba kuyimfuneko ukusebenzisa uluhlu olubanzi, iinguqu ezikhethekileyo ze-valve zingasetyenziswa.

Ukukhuselwa kwe-valve

Kuyaziwa ukuba izinga lokugeleza kwamanzi kwisitulo se-valve lidlula kakhulu ijubane lokuhamba kwalo kumbhobho. Kwaye mhlawumbi, iincinci ezinamandla ezikhoyo emanzini zingonakalisi nje kuphela i-saddle, kodwa kunye ne-plunger (intonga ye-cylindrical). Ukukhusela i-valves relief relief, njengomthetho, i-pre-filter ifakwe phambi kwayo.

Iintlobo zeevilives

Ezi zilandelayo iindidi zezivini ziye zazeka: DM505, DM506, PRW25, KAT40, DM652, DM664, KAT30, RP45, DM604, DM613, DM810, DM814, DM815. Ziyahluka ngokwemiqathango yamandla, ukushisa okusebenzayo, izicwangciso zogonyamelo, izinto ezisetyenziselwa ukuvelisa. Umboleki ngamnye uya kuba nako ukukhetha ukhetho olufanelekileyo kwiindleko kunye neempawu.
