Zeziphi iimeko zokukhetha ivalve yebhabhathane yombane kunye nevalve yebhabhathane yepneumatic?

Izinto eziluncedo kunye nokusetyenziswa kombaneiivalve butterfly

Umbaneivelufa butterflysisixhobo esixhaphake kakhulu solawulo lokuhamba kwemibhobho, esinoluhlu olubanzi lokusetyenziswa kwaye lubandakanya iindawo ezininzi, ezinjengolawulo lokuhamba kwamanzi kwidama lomthombo wombane osebenza ngamanzi, ukulawulwa kokuhamba kolwelo lwamashishini kumzi-mveliso, njl. njl., kwaye oku kulandelayo kuya kukuthatha ukuba uqonde iimpawu, iingenelo kunye nokusetyenziswa kwevalve yebhabhathane yombane.

1. Ukutywinwa okulungileyo

Emva koko, indima yombaneivelufa butterflyisetyenziselwa ukulungelelanisa ukuhamba kwamanzi ngexesha, kwaye ijongene nokushisa okuphezulu kunye noxinzelelo oluphezulu xa usebenza, ngoko ke ukuba ukutywinwa akukuhle, kuya kukhokelela ekuvuzeni kwamanzi, kwaye akunakwenzeka ukuqinisekisa ukulungiswa okuchanekileyo kokuhamba. Ivalve yebhabhathane yombane inenkqubo yokutywina ekhethekileyo, ngoko itywinwa kakuhle kuluhlu lweqondo lobushushu eliphantsi kakhulu ukuya kutsho kubushushu obuphezulu, oko kukuthi, ukutywinwa kwevalve yebhabhathane yombane ayichatshazelwa bubushushu, kwaye iswitshi yohlengahlengiso lombane iluncedo kakhulu.

2. Ukuvuza kweZero

Eyona nto incomekayo kukuqina kweivelufa butterfly yombane, i-shaft diameter ye-valve ye-valve itywina ithatha ikhonkco elitywinwe kakhulu, ikhonkco lokutywina licinezelwe yigraphite, ikhonkco lokutywina kunye neplate yebhabhathane yevalve yebhabhathane yombane ayiyi kubamba, ngoko ukutywinwa kulungile, i-zero yokuvuza yokhuseleko lomlilo ivalve yebhabhathane yombane lukhetho olukhethwa ngabathengi abaninzi.

3. Ulungelelwaniso olufanelekileyo kunye nolawulo

Umbaneivelufa butterflysisixhobo esisetyenziselwa ukulawula ukuhamba kolwelo, ukongeza ekuthuthweni nasekulawuleni ulwelo, udaka kunye nezinye izinto ezine-viscosity ethile nazo zinokuthuthwa, kwaye ulwelo oluqokelelwe kumbhobho luncinci, kwaye ukuvuleka nokuvalwa kombane kukhawuleza kwaye kulula.

Kukho iintlobo ezininziiivalveesetyenziswa kushishino, kodwa kuthatha inzame eninzi yokuthenga ivalve eyanelisa ngokwenene, ivalve yebhabhathane yombane inoluhlu olubanzi lwezicelo, ukusebenza okuqinileyo kunye nokutywinwa okugqwesileyo, kwaye luhlobo lwevalve yombane yombane esetyenziswa kakhulu.

Izinto eziluncedo kunye nokusetyenziswa kwe-pneumaticiivalve butterfly

Ivalve yebhabhathane yepneumatic yenziwe nge actuator yomoya kunye aivelufa butterfly. Ivalve yebhabhathane yepneumaticyivalve yomoya esebenzisa ipleyiti yebhabhathane ejikelezayo ngesiqu sevalve ukuvula nokuvala ukuphumeza isenzo esivumelayo, ikakhulu isetyenziswa njengevalve yokuvala, kwaye ingaphinda iyilwe ukuba ibe nomsebenzi wohlengahlengiso okanye ivalve yecandelo kunye nokulungelelanisa, kwaye ivalve yebhabhathane isetyenziswa ngakumbi nangakumbi kwimibhobho yoxinzelelo oluphantsi olukhulu kunye nobubanzi obuphakathi. Ukuhlelwa kwevalve yebhabhathane yepneumatic: intsimbi engenastainless butterfly valve, ivalve yebhabhathane eqinileyo, ivalve yebhabhathane etywiniweyo, ivalve yebhabhathane ethambileyo, intsimbi yekhabhoni yomoya.ivelufa butterfly. Iingenelo eziphambili zevalve yebhabhathane yomoya, ulwakhiwo olulula, ubungakanani obuncinci, ubunzima obukhanyayo, ixabiso eliphantsi, ivalve yebhabhathane yepneumatic ibaluleke kakhulu, ifakwe kwijelo elimnyama elinobude obuphezulu, kulula ukusebenza ngeendlela ezimbini zolawulo lwevalve ye-solenoid yeendlela ezintlanu, kwaye inokulungelelanisa nokuhamba phakathi.

Kukho ezinye izinto ekufuneka zithathelwe ingqalelo kwinkqubo yomgubo wevalve yebhabhathane yepneumatic, njengale: izinto azikwazi ukukhawuleziswa ngokuthe ngqo kwipleyiti yevalve yevalve xa ifakwa kwitroli ukusuka phezulu (lo mandla empembelelo aya kwenza ukuba ivalve ingakwazi ukuvala ngokuqinileyo), kwaye uxinzelelo lwe-static lwento alufanele lugqithise uxinzelelo loyilo lwevalve yebhabhathane yepneumatic, njl.

Umahluko phakathi kwevalve yokulawula kunye ne-valve yesiqhelo ye-manual kukuba ayinakuthathwa njengenxalenye eyedwa, kodwa kufuneka ithathelwe ingqalelo njengenxalenye yenkqubo yokulawula ngokuzenzekelayo, iingxaki ezininzi ekusebenziseni i-valve yokulawula azikho ingxaki yokukhetha kunye noqwalaselo, kodwa ngenxa yokuba ukuqonda komsebenzisi kwevalve yokulawula akwanelanga, ivalve yokulawula ayizange ihlaziywe kwaye ilungelelaniswe nenkqubo yokulawula. Ngethuba nje siqonda isitshixo sengxaki, khetha i-valve ngokuchanekileyo, kwaye ulungise i-valve yokulawula kwi-system debugging stage, sinokunciphisa kakhulu izinga lokungaphumeleli kwaye senze inkqubo yokulawula ngokuzenzekelayo iqhube ngokuzinzileyo ixesha elide.
