Ho hlahloba valve ke ho itšetleha ka ho phalla ha seaplane ka boeona 'me ka boeona ho bula le ho koala li-valve disc, e sebelisetsoang ho thibela phallo ea mecha ea litaba, e tsejoang hape e le valve ea ho hlahloba, valve ea tsela e le' ngoe, valve ea countercurrent le valve ea khatello ea morao.
Lekola ts'ebetso ea valve
Ho hlahloba valve ke mofuta oa valve o itekanetseng, mosebetsi oa oona o ka sehloohong ke ho thibela ho khutla ha mecha ea litaba, ho thibela pompo le ho khanna koloi, hammoho le ho tsoa ha setshelo.Li-valve tsa ho hlahloba li ka boela tsa sebelisoa ho fana ka melapo eo khatello e ka 'nang ea phahama ho feta khatello ea tsamaiso tsamaisong e thusang.
Sehlopha sa li-valve tsa ho hlahloba
Li-valve tsa ho hlahloba li ka aroloa ho latela sebopeho sa tsona le ho kenya:
1. Swing ho hlahloba valve
Swing check valve disc disc, e potolohang ho pota-pota setulo sa setulo sa li-valve bakeng sa motsamao oa rotary, hobane mocha oa valve o kena ka mokhoa o lekanang, ho hanyetsa ha phallo ho nyane ho feta valve ea ho phahamisa, e loketseng lebelo le tlaase le phallo e sa fetoheng hangata liketsahalong tse kholo tsa bophara. , empa eseng bakeng sa phallo ea pulsating, ts'ebetso ea eona ea ho tiisa ha e ntle joalo ka ho phahamisa.Swing check valve e arotsoe ka mefuta e le 'ngoe, habeli le halofo ea mefuta e meraro, mefuta ena e meraro e arotsoe haholo-holo ho ea ka bophara ba valve, sepheo ke ho thibela seaplane ho emisa ho phalla kapa ho phalla ka morao, ho fokolisa tšusumetso ea hydraulic.
2. Phahamisa valve ea ho hlahloba
Disc haufi le mola o otlolohileng oa "valve body slide check valve", ho phahamisa valve ho ka kenngoa feela ka pipeline e otlolohileng, ka khatello e phahameng e ka sebelisoang ka har'a bolo.Phahamisa sebopeho sa 'mele oa li-valve le li-valve tsa lefats'e (e ka sebelisoa ka valve ea lefats'e), kahoo mokelikeli oa eona oa ho hanyetsa mokelikeli o moholo.Sebopeho se tšoana le valve ea lefats'e, 'me' mele oa valve le disc li tšoana le valve ea globe.Karolo e ka holimo ea sekoahelo sa valve le karolo e ka tlaase ea sekoahelo sa valve e sebetsoa ka letsoho la tataiso, letlapa la tataiso la li-valve le ka lokoloha ho phahama le ho oa ka letlapa la tataiso ea lebone la valve, ha lebone le theoha tlaase, letlapa la li-valve ka sephara se bulehile, ha ho emisa ho emisa ho phalla, disc ea valve ka ho theola setulong, e thibela phello e mahareng ea countercurrent.Ka ho otloloha ka ho phahamisa tjheke phuputso e mahareng e kenang le tsela ya kanale ya ho tswa le tataiso ya kanale ya setulo se otlolohileng;Mohaho oa ho hlahloba li-valve tse otlolohileng, tsela ea eona ea ho kena le ea ho tsoa le tataiso ea mocha oa setulo e tšoana, ho hanyetsa ho phalla ho nyane ho feta ho otloloha.
3. Disc check valve
Belofo ea ho hlahloba moo disc e potolohang ho pota pin setulong.Sebopeho sa li-valve tsa li-disc se bonolo, se ka kenngoa feela ka liphaephe tse tšekaletseng, ho tiisa ho fokola.
4. Phapa e hlahloba valve
Valofo moo disc e thellang haufi le bohareng ba 'mele.Pipe check valve ke valve e ncha, molumo oa eona o monyenyane, boima bo bobebe, theknoloji e ntle ea ho sebetsa, ke e 'ngoe ea tataiso ea nts'etsopele ea valve ea ho hlahloba.Empa mokelikeli o thibelang metsi o kholoanyane ho feta li-valve tsa swing check valve.
5. Valofo ea ho hlahloba khatello
Sephahla sena se sebelisetsoa metsi a phepelo ea boiler le valve e khaotsoeng ea mouoane, e na le valve ea ho phahamisa le valve ea globe kapa Angle valve e kopantsoeng.
Nortech ke e 'ngoe ea baetsi ba li-valve tsa indasteri ba etelletseng pele Chaena ba nang le setifikeiti sa boleng sa ISO9001.
