I-SX-12 Ivalvu yokusabalalisa i-SX-14 ivalvu eyinhloko Ivalvu engenisa uwoyela ibhulokhi emaphakathi yokuthula

Iningi labavubukuli linamaphampu amabili amakhulu, ngakho-ke i-valve enkulu yokusiza inamabili (owaziwa nangokuthi i-valve yokuphepha eyinhloko), ngokulandelanayo lawula iphampu eyinhloko, bese iphampu ngayinye ilawula izenzo ezi-3, ibhakede kanye nengalo enkulu yokuhamba nohlangothi olulodwa. iyiqembu, ingalo ephakathi, ukuzungezisa kanye nokungaphandle kokuhamba okuseceleni kuyiqembu, wonke amavalvu okusiza amabili amakhulu (amavalvu okusiza umshayeli) alawula izenzo ezintathu eziphambene.

Futhi ekugcineni banamavalvu abo okusiza isenzo ngasinye, njengengalo ephakamisayo kanye nengalo eyehlisayo enamavalvu awo okusiza. I-valve yokusiza eyinhloko ilawula ngokuyinhloko ukucindezelwa kwamaphampu amabili amakhulu, ngakho-ke ukucindezela kwezenzo ezintathu ezilawulwa yipompo eyinhloko kuyafana, ngokuvumelana nezidingo, uma ukucindezela kwesenzo esisodwa kunganele noma kuphezulu kakhulu, khona-ke i-valve yokusiza ehlukile yesenzo ingalungiswa.

Isimiso sokusebenza kanye nomsebenzi we-valve yokusiza

I-1, umphumela wokuchichima kwe-valve yokusiza njalo: ohlelweni lokulawula i-quantitative pump throttling, iphampu yobuningi inikeza ukugeleza okuqhubekayo. Lapho ingcindezi yesistimu ikhuphuka, isidingo sokugeleza sizokwehla. Ngalesi sikhathi, i-valve yokusiza ivuliwe, ukuze ukugeleza okweqile kugeleze kubuyele ku-tank, ukuqinisekisa ukuthi i-valve yokusiza i-inlet pressure, okungukuthi, ukucindezela kokuphuma kwepompo kuhlala njalo (i-valve port ivame ukuvulwa ngokushintshashintsha kwengcindezi) .

2, ukuvikelwa kokuphepha: Uma uhlelo lusebenza ngokujwayelekile, i-valve ivaliwe. Kuphela lapho umthwalo udlula umkhawulo oshiwo (ingcindezi yesistimu idlula ingcindezi ebekiwe), ukuchichima kuvulwa ukuze kuvikelwe ukulayisha ngokweqile, ukuze ukucindezela kwesistimu kungasakhushulwa (ngokuvamile ukucindezela okuhleliwe kwe-valve yokusiza ku-10% kuya ku-20% ngaphezu kokucindezela okukhulu kokusebenza kwesistimu).

3, njenge-valve yokuthulula esetshenziswa njengesilawuli sokucindezela esikude:

I-valve yokulawula i-multistage ephezulu nephansi isetshenziswa njenge-valve yokulandelana ukukhiqiza ukucindezela emuva (intambo kumjikelezo kawoyela wokubuya).

I-valve yokusiza umshayeli inezingxenye ezimbili: i-valve eyinhloko kanye ne-pilot valve. Amavalvu okushayela ayafana namavalvu okusiza asebenza ngokuqondile, kodwa ngokuvamile amavalvu e-cone (noma ama-ball valve) ayizakhiwo zezihlalo ezimise okwezihlalo. I-valve eyinhloko ingahlukaniswa ibe yisakhiwo esisodwa esigxilile, isakhiwo esigxilile ezimbili kanye nesakhiwo se-concentric ezintathu.
