Ho sa tsotellehe hore na e bitsoa joang, ho ea ka moelelo oa sebele, re ka ahlola hoo e ka bang karolo ea valve ea ho hlahloba ho thibela mokelikeli ho khutlela tsamaisong le ho etsa bonnete ba hore mokelikeli o ka tsamaea feela ka tsela e tsitsitseng. Ho bula le ho koaloa ha valve ea ho hlahloba ho phethoa ka matla a phallo ea mokelikeli, kahoo valve ea ho hlahloba ke mofuta oa valve o itekanetseng. Ka lebaka la litšobotsi tsa eona, tekanyo ea tšebeliso ea li-valve tsa ho hlahloba bophelong e kholo haholo.

Tse peli. Kenyelletso ea ho hlophisoa ha li-valve tsa cheke

Li-valve tsa rona tse tloaelehileng le tse sebelisoang hangata li na le mefuta e meraro: mofuta oa ho phahamisa, mofuta oa rotary le mofuta oa disc. Lintlha tse latelang li kenyelletsa litšobotsi tsa li-valve tse tharo tse fapaneng:

1. Kenyelletso ea ho phahamisa valve ea ho hlahloba

Phahamisa ho hlahloba valve e arotsoe ka mefuta e 'meli: e rapameng le e otlolohileng ho latela mokhoa oa ho beha sesebelisoa. Ebang e rapame kapa e theohile, e tsamaea haufi le axis ho phethela ho bula le ho koala.

K. Bakeng sa merero e meng e hlokang boleng ba boenjineri bo batlang bo le holimo, hangata re sebelisa li-valve tsa ho hlahloba tse khutsitseng tsa mofuta oa lift. Ka kakaretso, re kenya valve ea ho hlahloba sebakeng sa pompo;

B. Ka kakaretso, li-valve tsa ho hlahloba ho khutsisa hangata li sebelisoa phepelong ea metsi le tsamaiso ea drainage ea meaho e phahameng. E le ho qoba ho thibeloa, valve ea ho hlahloba ho khutsisa hangata ha e sebelisoe bakeng sa ho ntša likhoerekhoere;

C. Phallo ea likhoerekhoere e sebetsoa ke valve e inehetseng e otlolohileng. Ka kakaretso e sebelisoa ho ts'ehetsa libaka tsa lehae joalo ka lipompo tsa metsi le likhoerekhoere.

2. Li-valve tsa ho hlahloba li-rotary li arotsoe ka mefuta e meraro: valve e le 'ngoe, li-valve tse peli le li-valve tse ngata ho latela mekhoa ea bona e fapaneng ea ho hlahloba. Molao-motheo oa bona oa ts'ebetso ke ho qeta ho potoloha ka setsi sa eona ebe o qeta ho bula le ho koala.

A. Tšebeliso ea li-valve tsa ho hlahloba li-rotary e batla e tsitsitse, 'me e sebelisoa ka kakaretso lits'ebetsong tsa phepelo ea metsi litoropong, empa ha e ea lokela liphaephe tsa likhoerekhoere tse nang le litšila tse ngata;

B. Har'a li-valve tse fapaneng tsa ho hlahloba rotary, valve ea ho hlahloba lekhasi le le leng e sebelisoa haholo. Ha e hloke boleng bo phahameng ba mokelikeli 'me hangata e sebelisoa phepelong ea metsi le drainage, petroleum, lik'hemik'hale, metallurgical le mesebetsi e meng. Haholo-holo libakeng tse ling tse thibetsoeng, valve ea ho hlahloba lekhasi le le leng e sebelisitsoe haholo;

3, ho hlahisoa ha valve ea ho hlahloba mofuta oa disc

A. Li-valve tsa tlhahlobo ea mofuta oa disc hangata li otlolohile. Li-valve tsa ho hlahloba li-valve tsa mofuta oa serurubele li sebelisoa haholo phepelong ea metsi le likhoeleng tsa meaho e phahameng, 'me maro a mang aa senya kapa a sebelisoa litsing tse ling tsa likhoerekhoere;
