Li-valve tse laolang khatello li laola khatello, eseng ho phalla, 'me lia itaola.
Mofuta oa taolo ea khatello
Ho na le mefuta e 'meli e meholo ea li-valve tse laolang khatello:li-valve tse fokotsang khatello le li-valve tsa khatello ea morao.
Li-valve tse fokotsang khatello li laola phallo ea khatello ho ea ts'ebetsong ka ho utloa khatello ea kantle le ho laola khatello e tlase ho eona.
Balaoli ba khatello ea morao ba laola khatello ho tloha ts'ebetsong ka ho utloa khatello ea ho kena le ho laola khatello e tsoang holimo
Khetho ea hau e nepahetseng ea taolo ea khatello e ipapisitse le litlhoko tsa ts'ebetso ea hau. Ka mohlala, haeba u hloka ho fokotsa khatello e tsoang mohloling o phahameng oa khatello pele mecha ea litaba ea tsamaiso e fihla ts'ebetsong e kholo, valve e fokotsang khatello e ka etsa mosebetsi. Ka lehlakoreng le leng, valve ea khatello ea morao e thusa ho laola le ho boloka khatello e holimo ka ho imolla khatello e feteletseng ha maemo a tsamaiso a etsa hore khatello e be e phahameng ho feta e hlokahalang.

Molao-motheo o sebetsang oa valve e laolang khatello
Li-valve tse laolang khatello li na le likarolo tse tharo tsa bohlokoa tse li thusang ho laola khatello:
Likarolo tsa taolo, ho kenyelletsa setulo sa valve le poppet. Setulo sa valve se thusa ho laola khatello le ho thibela mokelikeli ho tsoa ka lehlakoreng le leng la molaoli ha o koetsoe. Ha tsamaiso e ntse e phalla, setulo sa poppet le valve se sebetsa 'moho ho phethela mokhoa oa ho tiisa.
Sensing element, hangata diaphragm kapa piston. Ntho ea kutlo e etsa hore poppet e phahame kapa e oele setulong sa valve ho laola khatello ea ho kena kapa ea ho tsoa.
Loading Elements. Ho itšetlehile ka kopo, molaoli e ka 'na ea e-ba regulator e tletseng nako ea selemo kapa molaoli oa dome-loaded. Karolo e kenyang e na le matla a ho leka-lekanya tlase holim'a diaphragm.
Lintlha tsena li sebetsa 'moho ho theha taolo e lakatsehang ea khatello. Piston kapa diaphragm e utloa khatello ea metsi holimo (ho kena) le khatello ea tlase (ho tsoa). Sensing element ebe e leka ho fumana ho leka-lekana le matla a behiloeng ho tsoa ho karolo ea ho jarolla, e lokisoang ke mosebelisi ka mohele kapa mochini o mong oa ho thinya. Sensing element e tla nolofalletsa poppet ho bula kapa ho koala ho tloha setulong sa valve. Lintlha tsena li sebetsa 'moho ho boloka botsitso le ho finyella khatello e behiloeng. Haeba matla a le mong a fetoha, matla a mang a tlameha ho fetoha ho khutlisetsa tekano.
Ka valve ea ho fokotsa khatello, matla a mane a fapaneng a tlameha ho leka-lekana, joalokaha ho bontšitsoe setšoantšong sa 1. Sena se kenyelletsa matla a ho laela (F1), matla a ho kenya letsoho (F2), khatello ea ho tsoa (F3) le khatello ea ho kena (F4). Kakaretso ea matla a ho laela e tlameha ho lekana le motsoako oa matla a selemo a kenang, khatello ea ho tsoa le khatello ea ho kena.
Li-valve tsa khatello ea morao li sebetsa ka mokhoa o ts'oanang.
