Ivalvu yokulinganiselaI-valve inomsebenzi okhethekileyo, ineempawu ezilungileyo zokuhamba, isalathiso sezinga lokuvula ivalve, isixhobo sokutshixa isidanga sokuvula kunye nokumisela ukuhamba kwevalve yokulinganisa uxinzelelo. Ukusetyenziswa kwezixhobo ezikhethekileyo ezikrelekrele, faka uhlobo lwevalve kunye nexabiso lokuvula, ngokwesiginali yoxinzelelo elinganisiweyo inokuboniswa ngokuthe ngqo ngexabiso lokuhamba kwevalve yokulinganisela, logama nje isekethe yesebe kunye nokungena komsebenzisi kufakwe kwiinkcukacha ezifanelekileyo zevalve yokulinganisela, kunye nezixhobo ezikhethekileyo ezikrelekrele zokulungisa ingxaki ngexesha elinye, ungenza ukuhamba komsebenzisi ngamnye kufikelelwe kwixabiso elimiselweyo.
Ukwahlulwa kwevalvu yokulinganisela
Ivalvu yokulinganisela ikwimeko ye-hydraulic, dlala ivalvu yokulungisa ibhalansi eguquguqukayo nengaguqukiyo.
Ivalvu yebhalansi engashukumiyo ikwaziwa ngokuba yivalvu yebhalansi, ivalvu yebhalansi yesandla, ivalvu yebhalansi yokutshixa yedijithali, ivalvu yohlengahlengiso lweendawo ezimbini, njl., kukutshintsha i-spool kunye nomsantsa wesihlalo (ukuvula), ukutshintsha ukumelana nokuhamba ngevalvu ukufezekisa injongo yokulungisa isantya sokuhamba, injongo yesenzo sayo kukuxhathisa kwenkqubo, ukukwazi ukulinganisela ukusasazwa kwamanzi amatsha ngokuhambelana noyilo lomlinganiselo obaliweyo wamasebe ahlukeneyo ngaxeshanye ngokulingana nokwanda okanye ukwehla, kwaye isahlangabezana neemfuno zemozulu zangoku phantsi kwemfuno yokuhamba kwenxalenye yomthwalo, idlala indima kubushushu benkqubo, kunye nokunikezelwa kwamanzi kunye nokusasazwa kwebhalansi entsha yamanzi. Inxalenye yemfuno yokuhamba komthwalo, idlala indima yebhalansi yobushushu.
Iivalvu zokulinganisela eziguquguqukayo zahlulwe zaba ziivalvu zokulinganisela ukuhamba komoya eziguquguqukayo, iivalvu zokulinganisela uxinzelelo oluguquguqukayo, iivalvu zokulawula uxinzelelo oluguquguqukayo ezizisebenzela ngokwazo, njalo njalo. Ivalvu yokulinganisela ikwicandelo leevalvu ezilawulayo, umgaqo wayo osebenzayo kukutshintsha isithuba kunye nomsantsa wesihlalo (oko kukuthi, ukuvuleka), ukutshintsha ukuhamba kolwelo ngokusebenzisa ukumelana nokuhamba kwevalvu, ukufezekisa injongo yokulawula ukuhamba komoya. Ivalvu yokulinganisela ilingana nokumelana kwendawo inokutshintsha i-throttle element, kwiilwelo ezingacinezelekiyo, nge-flow equation inokufumaneka.
Iimpawu zevalvu yokulinganisela
Iimpawu zokuhamba komgca, oko kukuthi, kwimeko yoxinzelelo oluqhubekayo lomahluko ngaphambi nasemva kwevalvu, izinga lokuhamba kunye nenqanaba lokuvula ubudlelwane obucwangcisiweyo obufanayo;
Ngophawu oluchanekileyo lokuvula;
Kukho isixhobo sokutshixa isidanga sokuvula, abangengabo abaphathi abanakuyitshintsha ngokungacwangciswanga inqanaba lokuvula; uqhagamshelo lwetafile, banokubonisa ngokulula ivalvu ngaphambi nasemva koxinzelelo oluhlukileyo kunye nokuhamba ngevalvu. Nangona ivalvu yokulinganisela ineengenelo ezininzi, kodwa ukusetyenziswa kwayo kwinkqubo yamanzi okupholisa umoya kusekho iingxaki ezininzi. Ukuba ezi ngxaki azisonjululwanga kakuhle, iimpawu zevalvu yokulinganisela aziveli ngokupheleleyo. Indima yevalvu yokulinganisela kukulawula inkqubo, indawo nganye yokusasazwa (njengebhloko nganye yokwakha) yokuhamba kwangaphambili. Ngokufaka ivalvu yokulinganisela kwindawo yokungena yesakhiwo ngasinye, ukuhamba okupheleleyo kwenkqubo yokufudumeza kunokusasazwa ngokufanelekileyo.
Umgaqo wevalvu yokulinganisela
Ulawulo oluchaseneyo emzimbeni wevalvu, xa uxinzelelo kwindawo yokungena lusanda, lunciphisa ngokuzenzekelayo ububanzi bendlela kwaye lunciphise utshintsho kwisantya sokuhamba, kwaye ngokuchaseneyo. Ukuba uqhagamshelo olubuyela umva, le nkqubo yokulawula ayisebenzi. Ngaphezu koko, isiqwenga sevalvu, esisebenza njengomlawuli, sibhekisa kwicala, kwaye uxinzelelo olubuyela umva lunokunciphisa okanye luvale ukuhamba.
Ekubeni ivalvu yokulinganisela ifakwe ukuze kufudunyezwe ngcono, akukho mbuzo wokuyibuyisela umva. Ukuba ifakwe ngasemva, yimpazamo yomntu, eya kulungiswa ngokuqinisekileyo. Iivalvu zokulinganisa ziphantsi koluhlu lweevalvu ezilawulayo, kwaye umgaqo wayo osebenzayo kukutshintsha ukumelana nokuhamba kolwelo oluhamba ngevalvu ngokutshintsha umsantsa (oko kukuthi, ukuvuleka) phakathi kwespool kunye nesihlalo sevalvu ukufezekisa injongo yokulawula ukuhamba.
Ngaphandle koko, iTianjin Tanggu Water Seal Valve Co., Ltd. yivalvu yesihlalo ethambileyo ephucukileyo exhasa amashishini, iimveliso zayoivalvu yebhabhathane yesihlalo esithambileyo, ivalvu yebhabhathane ye-lug, ivalvu yebhabhathane edibeneyo ephindwe kabini,ivalvu yebhabhathane engaqhelekanga ephindwe kabini, ivalvu yokulinganisela, ivalvu yokujonga iipleyiti ezimbini ze-wafer, i-Y-Strainer njalo njalo.
