Iivalvu zokuvala i-fuel zizinto ezibalulekileyo ngaphakathi kwenkqubo njengoko zimele isixhobo sokhuseleko esilungileyo. Indima ephambili edlalwa sesi sixhobo kukunqanda kunye nokuthintela i-fuel ngaphambi kokuba ifike kwi-burner, ngaloo ndlela igweme ukushisa okubilisayo kwesekethe engena kwinkqubo ukuba ifikelelwe. Oku kubonisa indlela yokuphepha umonakalo kwinkqubo ngokwayo kodwa nakubantu abakummandla wayo.

Isebenza njani ivalve yokuvala amafutha?

Kukho izinto ezimbini ezibalulekileyo zevalve:
- Umzimba wevalvu: ngaphakathi apho isibaso, ulwelo okanye igesi, idlula;
- Isixhobo solawulo: sixhotyiswe ngento enovakalelo.
Intonga ye-shutter ixhunyiwe kwisixhobo sokulawula kwaye ibangela ukuvala i-valve ukuba kuyimfuneko. Ukuba yonke into isebenza ngokuchanekileyo, intonga ye-shutter ixhomekeke kwipiston kwaye iqinisekisa ukuhamba kwamafutha. Nangona kunjalo, ukuba kukho ukungasebenzi kakuhle okanye ukungahambi kakuhle, i-piston iyashukuma kwaye ibangele ukuvala ngokuthoba intonga yokuvala. Zeziphi ezi meko?
- Ukwandiswa okugqithisileyo kwe-fluid: i-piston ihambela ngakwesobunxele kwaye ibangela ukuba intonga yehle, ivale i-fuel passage;
- Ukuqhekeka kwe-capillary: i-piston ihambela ngasekunene kwaye ibangela, kwakhona, ukuhla kwentonga kunye nokuvalwa kwepaseji.
Emva kokuba i-valve ivaliwe, kunokwenzeka ukuba ubuyele ekusebenzeni kuphela ngokuphinda kusetyenziswe incwadi enokuthi yenzeke kuphela ukuba i-fluid ineqondo lokushisa elingaphantsi kwe-87 ° C kwaye i-capillary ayiphukile okanye yonakaliswe.
