(1) Iivalvu zebhola eziphefumulayo
Ivalve yebhola ye-pneumatic inevalve yebhola kunye ne-actuator yomoya.Ngokuqhelekileyo kufuneka isetyenziswe ngokubambisana nezixhobo ezibandakanya ivalve yamagnetic, unyango lomoya FRL, umda wokutshintsha, kunye ne-positioner ukwenzela ukuba ilawulwe kude kunye nasekhaya kunye nokuvulwa kunye nokuvalwa kwigumbi lokulawula.Iphucula ukhuseleko, ubukhulu becala igcina iindleko zabasebenzi kunye nexesha, kwaye yenza ulawulo lwezandla kwisiza, ngaphezu komhlaba kunye nakwiindawo ezinobungozi ezingafunekiyo.
(2) Ukuhlelwa kweevalvu zebhola zepneumatic
Ngokwemathiriyeli, iivalvu zebhola zepneumatic zinokwahlulwa zibe ziivalve zebhola zepneumatic steel stainless, iivalvu zebhola zepneumatic, iivalve zebhola zepneumatic sanitary, iivalvu zebhola zentsimbi yentsimbi, iivalvu zebhola zepneumatic zentsimbi, njl.
Ngokwemowudi yoqhagamshelo, iivalve zebhola yepneumatic zinokwahlulwa zibe ziivalve zepneumatic flanged ibhola, screw thread pneumatic ball valves, welded pneumatic valves, njl.
Ngokoxinzelelo, iivalve zebhola zepneumatic zinokwahlulwa zibe ziivalve zebhola zepneumatic eziphantsi, uxinzelelo oluphakathi lwe-pneumatic ball valves kunye noxinzelelo oluphezulu lwe-pneumatic ball valves.
Ngokwendawo yetshaneli, iivalvu zebhola yepneumatic zinokwahlulwa zibe ziivalve zebhola ephuma emoyeni, iindlela ezintathu zebhola ye-pneumatic kunye ne-right-angle ye-right-angle yebhola ye-pneumatic.
Ngokweempawu zebhola, iivalvu zebhola ye-pneumatic zinokwahlulwa zibe ziivalve zebhola ezidadayo kunye ne-trunnion ball valves.
Ibhola edadayo
Ibhola yevalve yebhola edadayo iyadada.Ngaphantsi kweempembelelo zoxinzelelo oluphakathi, ibhola iya kutshintsha kwaye igxininiswe ngokuqinileyo kwindawo yokutywinwa kwendawo yokuphuma ukuze kuqinisekiswe ukusebenza kokutywinwa kokuphela kokuphuma.
Ibhola elungisiweyo
Ibhola yevalve ye-trunnion ibhola ilungisiwe, kwaye ayiyi kutshintsha emva kokucinezelwa.Zonke iivalvu zebhola zetrunnion zinesitulo sevalve edadayo.Ngaphantsi kwempembelelo yoxinzelelo oluphakathi, i-valve iqala ukuhamba ukwenza umsesane wokutywina ucinezele kwibhola ukuze kuqinisekiswe ukusebenza kokutywinwa.
(3) Iivalvu zebhola zombane
Ivalve yebhola yombane yenziwe yi-actuator kunye nevalve yebhola.Luhlobo lwesixhobo esisetyenziselwa imibhobho kushishino oluzenzekelayo kunye nolawulo lwenkqubo.Ukuchaneka, ngokuqhelekileyo isetyenziselwa ulawulo olukude lwemibhobho yeendaba.
Ngokwenkcazo yevalve yebhola yombane "kwiLuhlu lwamagama eevalvu", ivalve yebhola yombane luhlobo lwevalve (iibhola) eziqhutywa sisikhondo sevalve, kwaye emva koko ijikeleze i-axis yevalve.Iivalvu zebhola zombane zisetyenziselwa ukusika kunye nokungena kwimidiya, okanye zisetyenziselwa ukulawula nokulawula imidiya kwimibhobho.Ngokuphathelele ivalve yebhola etywiniweyo enobume obungu-V, kukho amandla aqinileyo okucheba phakathi kwebhola emile okwe-V kunye nesihlalo sevalve yentsimbi esenziwe ngokugquma kwekhabhide enesamente.
(4) Uthelekiso phakathi kweevalvu zebhola zepneumatic kunye neevalvu zebhola zombane
Iindleko
Ivalve yebhola yomoya inomthwalo onzima, kodwa inexabiso eliphantsi kunevalve yebhola yombane.Ke, ukusebenzisa iivalve zebhola yepneumatic kunokunciphisa iindleko zobunjineli.
Ukhuseleko lokusebenza
Abasebenzisi abasebenzisa ivalve yebhola yepneumatic banokuyivula okanye bayivale ivalve.Xa i-valve yebhola yombane ingenawo amandla, inokuhlala kuphela kwindawo yayo, ebonisa ukuba i-valve yebhola ye-pneumatic ineenzuzo ezinkulu kukhuseleko.Kuba xa ivalve yebhola yombane iphelelwe ngamandla, iya kuvala ukunqanda umva wesihluzi kunye nokuchitheka.I-valve yebhola ye-pneumatic ayifuni umbane, ngelixa i-valve yebhola yombane isebenzisa i-220V okanye isigaba sesithathu se-460V.Ukutsho ke, ivalve yebhola yombane iyingozi ngakumbi kwindawo efumileyo, kanti ivalve yebhola yomoya ayichatshazelwa yindawo efumileyo.Ngokumalunga nokugcinwa, kulula ukugcina i-valve yebhola ye-pneumatic kuba kukho inxalenye enye ehambayo.I-actuator yombane yevalve yebhola yombane kufuneka igcinwe ngabasebenzi ngenxa yeendawo ezininzi ze-actuator yombane.
Ukusebenza
Ivalve yebhola yepneumatic inokuziqhelanisa nomthwalo ogcwele rhoqo.Ivalve yebhola yombane ilinganiselwe ngumthamo womthwalo weemoto kunye namaxesha amaninzi okuqalisa ngeyure.
Imijikelo yobomi
Ivalve yebhola yepneumatic inomjikelo wobomi obude kunye nezenzo ezimalunga nezigidi ezi-2.Ukusetyenziswa okuphindaphindiweyo kokusetyenziswa kwevalve yebhola ye-pneumatic inokulawulwa ngokuchanekileyo, enokuthi ifikelele kwi-0.25%.
Ukumelana nokubola
I-valve yebhola ye-pneumatic ene-epoxy coating ngaphakathi nangaphandle kwe-actuator ye-pneumatic inokulungelelaniswa okukhulu kwendawo yokusebenza.Iyakwazi ukuziqhelanisa nemeko yokusebenza embi njengokutsha, uqhushumbo, uthuli, i-ferromagnetic, i-radioactive, indawo eshukumayo, njl.
Eminye imiba
Xa i-valve yebhola ye-pneumatic ingasebenzi kakuhle, inokulungiswa okanye itshintshwe ngaphandle kwamandla okanye imithombo yomoya.Ngokumalunga nokugcinwa, i-valve yebhola ye-pneumatic ayifuni ioli, kanti i-valve yebhola yombane idinga inani elikhulu leoli.Ngokumalunga nokusebenza ngesandla, i-valve yebhola ye-pneumatic ingasebenza ngaphandle kwamandla.Malunga nesantya, ivalve yebhola yepneumatic isebenza kunye neempendulo ngokukhawuleza ukuze ilungelelanise ngokufanelekileyo.Isantya sevalve yebhola yombane sihlala sihleli kwaye asinakuguqulwa.
