Ulwazi oluqhelekileyo lweValve II

1, Ivalve yeendlela ezintathu Umzimba wevalve yendlela-ntathu unemilomo emithathu, elungele inkqubo yolawulo lwemibhobho yolwelo olumacala amathathu. Uninzi lwazo lusetyenziselwa ukulawulwa kweqondo lokushisa, ukulawulwa komlinganiselo kunye nokulawulwa kwe-bypass yokutshintshwa kobushushu. Ekusetyenzisweni, kufuneka sinikele ingqalelo kwintlukwano yeqondo lokushisa kwamanzi akufanele kube mkhulu kakhulu, ngokuqhelekileyo ngaphantsi kwe-150 C, ngaphandle koko i-valve yeendlela ezintathu iya kuba noxinzelelo olukhulu, ngaphandle koko i-valve yeendlela ezintathu iya kuba noxinzelelo olukhulu kwaye ibangele ukuguqulwa, okubangelwa ekuvuzeni okanye umonakalo kwisiphambuka. Ivalve eneendlela ezintathu inevalve edibanisa iindlela ezintathu kunye nevalve yendlela ezintathu. Ivalve yendlela-ntathu yokudibanisa yinto ephakathi engena kwaye iphuma kumazibuko amabini okungena emva kokuxuba. Ivalve yendlela-ntathu yoluleko yinto ephakathi equkuqela ngaphakathi isuka kwindawo enye kwaye yahlulwe yaba ziindawo zokuphuma ezimbini. 2. I-Cam Flexure Valve Cam flexure valve, eyaziwa ngokuba yi-eccentric rotary valve, ine-core spherical core efana ne-fan, ephoswe kwenye kunye nengalo ye-flexure kunye nomkhono kwaye igxininiswe kwi-shaft ejikelezayo. Ingalo ephambukayo inokuvelisa i-deflection phantsi kwesenzo soxinzelelo, okwenza umphezulu we-spherical we-valve core contact ngokusondeleyo kunye nomsesane wokuhlala kwaye unomsebenzi wokutywinwa kakuhle. Ineenzuzo zobunzima bokukhanya, umthamo omncinci, ukufakwa okufanelekileyo, kwaye ifanelekile kulawulo lokuhamba okuphakathi kunye ne-viscosity ephezulu kunye nomcimbi omisiweyo. 3. IValve yesitulo esinye esiNgqo Kukho isitulo esinye kuphela kunye ne-spool kumzimba wesitulo esinye. Iingenelo zayo zisakhiwo esilula kunye nesiphumo esihle sokutywinwa, kwaye luhlobo lomzimba wevalvu osetyenziswa ngakumbi. Ukungalungi kwayo kukuba inomthamo ophantsi wokujikeleza kunye namandla amakhulu angalinganiyo, angafanelanga uxinzelelo oluphezulu kunye nezihlandlo ezinkulu zecaliber. 4. IValve yesitulo esiNgqo ngokuNgqo Kukho izihlalo ezibini kunye nespools emzimbeni wevalve enezihlalo ezibini. Inzuzo kukuba amandla asebenza kwi-spools ephezulu kunye nesezantsi ye-fluid inokunciphisa omnye nomnye, ngoko ke i-valve yezihlalo ezimbini inomahluko omkhulu ovumelekileyo woxinzelelo. Ukungalungi kukuba i-spools ephezulu nangaphantsi akufanele ivalwe ngexesha elifanayo, ngoko ukuvuza kukhulu. Ilungele imidiya ecocekileyo kunye nokwahlukana okukhulu koxinzelelo kwiiphelo zombini zevalve kunye nemfuno ephantsi yokuvuza. Ayifanelekanga kwi-viscosity ephezulu kunye nezihlandlo ezinefiber.
