Indlela yokuguqula iValve Pressure PSI, BAR kunye neMPA?
Ukuguqulwa kwe-PSI kunye ne-MPA, i-PSI yiyunithi yoxinzelelo, ichazwa njenge-intshi yaseBritani / i-intshi yesikwere, i-145PSI = 1MPa, kunye ne-PSI yesiNgesi ibizwa ngokuba yi-Pounds per square in. Ungabala zonke iiyunithi ngeeyunithi zoluntu: 1bar≈14.5PSI, 1PSI = 6.895kpa = 0.06895bar Europe ...Funda ngokugqithisileyo -
Iimpawu ezihambayo zevalve yokulawula
Iimpawu zokuhamba kwevalve yokulawula ikakhulu ziquka iimpawu ezine zokuhamba: umgca ochanekileyo, ipesenti elinganayo, ukuvulwa ngokukhawuleza kunye neparabola. Xa ifakwe kwinkqubo yokulawula yangempela, ukunyanzeliswa kokwahlukana kwevalve kuya kutshintsha ngokutshintsha kwesantya sokuhamba. Oko kukuthi, xa...Funda ngokugqithisileyo -
Zisebenza njani iivalvu zokulawula, iivalvu zeglowubhu, iivalvu zesango kunye neetshekhi
Ivalve elawulayo, ekwabizwa ngokuba yivalve yokulawula, isetyenziselwa ukulawula ubungakanani bolwelo. Xa inxalenye elawulayo yevalve ifumana isignali elawulayo, isiqu sevalve siya kulawula ngokuzenzekelayo ukuvuleka nokuvalwa kwevalve ngokwesiginali, ngaloo ndlela ilawula isantya sokuhamba kolwelo kunye...Funda ngokugqithisileyo -
Yintoni umahluko phakathi kwevalve yesango kunye nevalve yebhabhathane?
Iivalve zesango kunye neevalve zebhabhathane zizivalo ezimbini ezixhaphake kakhulu. Bahluke kakhulu ngokwezakhiwo zabo, iindlela zokusetyenziswa, kunye nokulungelelaniswa kweemeko zokusebenza. Eli nqaku liza kunceda abasebenzisi baqonde ngcono umahluko phakathi kweevalve zesango kunye ne-butterfly valves. Uncedo olungcono...Funda ngokugqithisileyo -
Umahluko omkhulu phakathi kwevalve yokunciphisa uxinzelelo kunye nevalve yokhuseleko
1. I-valve yokunciphisa uxinzelelo yi-valve eyanciphisa uxinzelelo lwe-inlet kuxinzelelo oluthile olufunekayo lokuphuma ngohlengahlengiso, kwaye ithembele kumandla ophakathi ngokwawo ukugcina ngokuzenzekelayo uxinzelelo oluzinzileyo lokuphuma. Ukusuka kwindawo yokujonga ubuchwephesha be-fluid, uxinzelelo lokunciphisa i-va...Funda ngokugqithisileyo -
Isishwankathelo somahluko phakathi kweevalvu zeglowubhu, iivalvu zebhola kunye neevalvu zesango
Masithi kukho umbhobho wokuhambisa amanzi onesigqubuthelo. Amanzi atofwa ukusuka ezantsi kombhobho aze akhutshelwe kumlomo wombhobho. Isigqubuthelo sombhobho wokuphuma kwamanzi silingana nelungu lokuvala levalve yokumisa. Ukuba uphakamisela isigqubuthelo sombhobho phezulu ngesandla sakho, amanzi aya kuba yidiski...Funda ngokugqithisileyo -
Lithini ixabiso leCV yesivalo?
Ixabiso le-CV ligama lesiNgesi elithi Circulation Volume Isishunqulelo somthamo wokuqukuqela kunye ne-flow coefficient sisuka kwinkcazo ye-valve yomlinganiso wokuhamba kummandla wolawulo lobunjineli bolwelo eNtshona. I-flow coefficient imele umthamo wokuqukuqela kwento ukuya kumbindi, i-spec...Funda ngokugqithisileyo -
Ingxoxo emfutshane ngomgaqo wokusebenza kunye nokusetyenziswa kweendawo zokubeka iivalvu
Ukuba uhamba ujikeleza iworkshop yezityalo zemichiza, ngokuqinisekileyo uya kuyibona eminye imibhobho exhotyiswe ngeevalvu ezinentloko engqukuva, eziziivalvu ezilawulayo. Ivalve elawula i-pneumatic diaphragm Unokwazi ulwazi oluthile malunga nevalve elawulayo kwigama layo. Igama eliphambili elithi "umgaqo ...Funda ngokugqithisileyo -
Ukuqaliswa kwenkqubo yokuphosa ivalve
Ukujulwa komzimba wevalvu yinxalenye ebalulekileyo yenkqubo yokwenziwa kwevalvu, kwaye umgangatho wevalve yevalve umisela umgangatho wevalvu. Oku kulandelayo kwazisa iindlela ezininzi zenkqubo yokugalela edla ngokusetyenziswa kushishino lwevalvu: Ukubunjwa kwesanti: Ukugalelwa kwesanti c...Funda ngokugqithisileyo
