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 losetyenziso kwaye sibandakanya iindawo ezininzi, ezinjengolawulo lokuhamba kwamanzi kwidama lomthombo wamandla ombane wamanzi, ulawulo lokuhamba kolwelo kwimizi-mveliso, 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 nobushushu obuphezulu kunye noxinzelelo oluphezulu xa isebenza, ngoko ke ukuba ukutywinwa akulungile, kuya kubangela ukuvuza kwamanzi, kwaye akunakwenzeka ukuqinisekisa ukulungiswa okuchanekileyo kokuhamba. . Ivalve yebhabhathane yombane inenkqubo yokutywina ekhethekileyo, ngoko inokutywinwa kakuhle kuluhlu lweqondo lobushushu eliphantsi kakhulu ukuya kumaqondo aphezulu, oko kukuthi, ukutywinwa kwevalve yebhabhathane yombane ayichatshazelwa bubushushu, kwaye iswitshi yohlengahlengiso lombane elula kakhulu.

2. Ukuvuza kweZero

Eyona nto incomekayo kukuqina kweivelufa butterfly yombane, i-shaft diameter ye-valve yesikhondo ithatha umsesane otywinwe kakhulu, umsesane wokutywina ucinezelwe yigraphite, umsesane wokutywina kunye nepleyiti yebhabhathane yevalve yebhabhathane yombane ayiyi kubambeka, ke ukutywinwa kuhle kakhulu, umlilo ovuzayo we-zero. Ivalve yombane yebhabhathane yokhuseleko lolona khetho lukhethwayo ngabathengi abaninzi.

3. Ulungelelwaniso olululo kunye nolawulo

Umbaneivelufa butterflysisixhobo esisetyenziselwa ukulawula ukuhamba kolwelo, ukongeza ekuthuthweni nasekulawuleni ulwelo, udaka kunye nezinye izinto ezineviscosity ethile nazo zinokuthuthwa, kwaye ulwelo oluqokelelwe kumbhobho luncinci, kwaye ukuvuleka nokuvalwa kombane kuyakhawuleza. 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 yepneumaticivelufa yomoya esebenzisa ipleyiti yebhabhathane ejikelezayo nesiqu sevalve ukuvula nokuvala ukufezekisa isenzo esivumelayo, esisetyenziswa ikakhulu njengevalve yokuvala, kwaye isenokwenziwa ukuba ibe nomsebenzi wohlengahlengiso okanye ivalve yecandelo kwaye ukulungiswa, kunye nevalve yebhabhathane isetyenziswa ngakumbi nangakumbi kwimibhobho ephantsi yoxinzelelo 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 yepneumatic, ulwakhiwo olulula, ubungakanani obuncinci, ubunzima obukhanyayo, ixabiso eliphantsi, ivalve yebhabhathane yepneumatic ibaluleke kakhulu, ifakwe kumjelo obumnyama obuphezulu, kulula ukusebenza ngeendawo ezimbini zolawulo lwevalve ye-solenoid yendlela ezintlanu, kwaye inokulungelelanisa i-flow medium.

Kukho ezinye izinto ezifunekayo ukuba zithathelwe ingqalelo kwinkqubo yomgubo wevalve yebhabhathane yepneumatic, njengale: izinto eziphathekayo azinakubalekiswa ngokuthe ngqo kwipleyiti yevalve yevalve xa ifakwa kwitroli ukusuka phezulu (le mpembelelo yempembelelo iya kwenza kwakhona i-valve ingakwazi ukuvala ngokuqinileyo), kwaye uxinzelelo lwe-static lwento akufanele ludlule uxinzelelo loyilo lwe-valve butterfly valve, njl.

Umahluko phakathi kwevalve yokulawula kunye ne-valve ye-manual yesiqhelo 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 yolawulo 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.
