Kukho umahluko ocacileyo phakathi kweevalvu zesango lesilayidi kunyeiivalvu zesango lemelangokwesakhiwo, umsebenzi kunye neemeko zesicelo:

1. Uyilo lwesakhiwo

Isango levalve yesango lokutyibilika lisicaba, kwaye umphezulu wokutywina udla ngokwenziwa nge-alloy eqinile okanye irabha. Ukuvulwa kunye nokuvalwa kufezekiswa ngokutyibilika okuthe tyaba kwesango ecaleni kwesitulo sevalvu. Ulwakhiwo lunobunzima, kwaye ukusebenza kokutywinwa kuxhomekeke ekuchanekeni kokufaneleka phakathi kwesango kunye nesihlalo sevalve.

Isango le-valve yesango lentsimbi ye-ductile ikwimo ye-blade, enokuthi inqumle imicu, amasuntswana kunye nobunye ukungcola phakathi. Inokwakheka okuthe kratya. Umphezulu wokutywina phakathi kwesango kunye nesihlalo sevalve ubukhulu becala uyilwe njengoqhagamshelwano oluqinileyo lwentsimbi, olunokumelana okuqinileyo.

2. Ukusebenza kokutywinwa

Ivalve yesango lokutyibilika inomsebenzi wokutywina kwaye ifanelekile ngakumbi kwizihlandlo ezineemfuno zokuvuza eziphezulu (ezifana nemidiya yegesi). Ezinye iimodeli zixhotyiswe ngesakhiwo sokutywinwa kabini.

Ukutywinwa kwevalve yesango yemela yeflange kugxininise ekuchaseni ukunxitywa kwaye kufanelekile kumajelo eendaba aqulathe amasuntswana aqinileyo, uludaka, njl njl. Indawo yokutywina inokulungiswa ngokusila, kodwa ukuvuza kukhulu kancinci kunoko kwevalve yesango lesilayidi.

3. Iimeko zesicelo

Iivalve zesango lokutyibilika zisetyenziselwa ukucoca imidiya efana negesi kunye neemveliso zeoyile, okanye kwiinkqubo zombhobho ezifuna ukutywinwa okungqongqo.

Ivalve yesango yemela enemoto ifaneleke ngakumbi kumajelo eendaba aqulathe ubumdaka obufana nelindle, ipulp, kunye nomgubo wamalahle, kwaye isoloko isetyenziswa kwimimandla efana nesinyithi, imigodi, kunye nokhuseleko lokusingqongileyo.

IValve ye-Jinbin igxile kwimveliso kunye nokwenza ngokwezifiso iivalvu zesango lomese ezinobubanzi obukhulu. Ivalve yesango yobukhulu obukhulu (enedayamitha ye-≥DN300) isetyenziswa ngokubanzi kwimibhobho yemizi-mveliso ngenxa yezakhiwo zayo kunye nezibonelelo zokusebenza.

I-plate yesango efana ne-knife iyakwazi ukunqumla kalula imicu, iincinci okanye izinto ze-viscous (ezifana ne-slurry, i-pulp) phakathi, ukuthintela ukungcola ukuba kuqokelele kwaye kuvimbele i-valve. Ilungele ngokukodwa ukuthutha imidiya equlethe into eqinileyo emisiwe, ukunciphisa ukuphindaphinda kokugcinwa kwemibhobho.

2. Umzimba wevalve wamkela uyilo oluthe tye, olunokumelana nokuhamba okuphantsi kunye nokuvula okufutshane kunye nokuvala isango. Xa idibene ne-actuator yombane okanye i-pneumatic actuators, inokufezekisa ukuvulwa ngokukhawuleza kunye nokuvala, ukunciphisa ubunzima bokusebenza kwee-valve ezinkulu ze-diameter kwaye zenze ukuba zilungele iimeko zokulawula i-automation.

3. Imiphezulu yokutywina ininzi yenziwe nge-alloy eqinile okanye intsimbi engagungqiyo, enomsebenzi oqinileyo wokuchasana nokukhukuliseka. Nangona isetyenziswe ixesha elide kumazinga aphezulu okuhamba okanye kwimidiya equkethe amaqhekeza, inokugcina ukusebenza kakuhle kokutywinwa kunye nokunciphisa iindleko zokutshintshwa.

4. Umzimba we-valve unesakhiwo esilula, unzima ngakumbi kunezinye iintlobo zeevalve ezinobubanzi obufanayo, kwaye uneemfuno eziphantsi zokuxhaswa kwemibhobho ngexesha lofakelo. Isango kunye nesihlalo sevalve sinokuchithwa kwaye sitshintshwe ngokwahlukileyo. Ngexesha lokugcinwa, akukho mfuneko yokutshintsha i-valve yonke, ukunciphisa iindleko zokugcina.

5. Iyakwazi ukuziqhelanisa nobushushu obuphezulu, uxinzelelo oluphezulu kunye nemidiya ebolileyo (njengamanzi amdaka ekhemikhali, i-acidic slurry). Ngokukhetha izinto ezinganyangekiyo kwi-corrosion (ezifana nensimbi engenasici, i-rubber-lined), inokuhlangabezana neemeko ezinzima zokusebenza kumashishini ahlukeneyo kwaye inamandla amaninzi.

Ukuba unazo naziphi na iimfuno ezinxulumeneyo, nceda uqhagamshelane nathi ngezantsi kwaye uya kufumana impendulo kwiiyure ezingama-24!
