Umahluko ophambili phakathi kwevalvu yokunciphisa uxinzelelo kunye nevalvu yokhuseleko
1. Ivalvu yokunciphisa uxinzelelo yivalvu enciphisa uxinzelelo lokungena ukuya kuxinzelelo oluthile olufunekayo lokukhupha ngokulungelelanisa, kwaye ixhomekeke kumandla esixhobo ngokwayo ukugcina ngokuzenzekelayo uxinzelelo lokukhupha oluzinzileyo. Ngokwembono ye-fluid mechanics, i-va yokunciphisa uxinzelelo...Funda ngokugqithisileyo -
Isishwankathelo somahluko phakathi kweevalvu zeglobe, iivalvu zebhola kunye neevalvu zesango
Masithi kukho umbhobho wokuhambisa amanzi onesiciko. Amanzi afakwa ezantsi kombhobho aze akhutshwe aye emlonyeni wombhobho. Isigqubuthelo sombhobho wokukhupha amanzi silingana nelungu lokuvala levalvu yokumisa. Ukuba uphakamisa isigqubuthelo sombhobho phezulu ngesandla sakho, amanzi aya kuba yidiski...Funda ngokugqithisileyo -
Ixabiso le-CV yevalvu lithini?
Ixabiso le-CV ligama lesiNgesi elithi Circulation Volume. Isifinyezo se-flow volume kunye ne-flow coefficient sivela kwinkcazo ye-valve flow coefficient kwicandelo lolawulo lobunjineli bolwelo eNtshona. I-flow coefficient imele umthamo wokuhamba kwe-e...Funda ngokugqithisileyo -
Ingxoxo emfutshane malunga nomgaqo wokusebenza kunye nokusetyenziswa kwee-valve positioners
Ukuba uhambahamba kwindawo yokusebenzela yezityalo zeekhemikhali, ngokuqinisekileyo uya kubona imibhobho exhotyiswe ngeevalvu ezineentloko ezijikelezileyo, ezilawula iivalvu. Ivalvu yokulawula i-diaphragm ye-pneumatic Ungayazi ulwazi oluthile malunga nevalvu yokulawula ukusuka kwigama layo. Igama eliphambili elithi "regulation...Funda ngokugqithisileyo -
Intshayelelo yenkqubo yokuphosa ivalvu
Ukuphoswa komzimba wevalvu yinxalenye ebalulekileyo yenkqubo yokwenziwa kwevalvu, kwaye umgangatho wokuphoswa kwevalvu umisela umgangatho wevalvu. Oku kulandelayo kwazisa iindlela ezahlukeneyo zenkqubo yokuphoswa ezisetyenziswa rhoqo kushishino lweevalvu: Ukuphoswa kwesanti: Ukuphoswa kwesanti c...Funda ngokugqithisileyo -
Uxinzelelo oluqhelekileyo lwe-PN kunye neepawundi zeKlasi (Lb)
Uxinzelelo oluqhelekileyo (PN), inqanaba leponti eliqhelekileyo leKlasi yaseMelika (Lb), yindlela yokubonisa uxinzelelo, umahluko kukuba uxinzelelo abalumeleyo luhambelana nobushushu obahlukileyo, inkqubo yePN yaseYurophu ibhekisa kuxinzelelo olukwi-120 ° C Uxinzelelo oluhambelanayo, ngelixa iCLass...Funda ngokugqithisileyo -
Yintoni umahluko phakathi kweValve yeSango kunye neValve yeButterfly?
Iivalvu zesango kunye neevalvu zebhabhathane ziivalvu ezimbini ezisetyenziswa kakhulu. Zahluke kakhulu ngokwezakhiwo zazo, iindlela zokusetyenziswa, kunye nokuzivumelanisa neemeko zokusebenza. Eli nqaku li...Funda ngokugqithisileyo -
Uhlalutyo lwezizathu ezine eziphambili zokuvuza kweevalvu zebhola kunye namanyathelo okujongana nazo
Ngokuhlalutya umgaqo wolwakhiwo lwevalvu yebhola yombhobho esisigxina, kwafunyaniswa ukuba umgaqo wokuvala uyafana, kusetyenziswa umgaqo "wesiphumo sepiston", kwaye kuphela ulwakhiwo lokuvala olwahlukileyo. Ivalvu ekusetyenzisweni kwengxaki ibonakaliswa kakhulu kwiindlela ezahlukeneyo ...Funda ngokugqithisileyo -
Zeziphi iingxaki ekufuneka siziqwalasele kwinkqubo yokuthengwa kwevalvu yesango elithambileyo?
Ndihlala ndidibana nemibuzo yabathengi efana nale ilandelayo: "Molo Beria, ndifuna ivalvu yesango, ungasicela ukuba sinike i-quote?" Iivalvu zesango ziimveliso zethu, kwaye siqhelene nazo kakhulu. I-quote ngokuqinisekileyo ayiyongxaki, kodwa ndingamnika njani i-quote ngokusekelwe kulo mbuzo? Indlela yokwenza...Funda ngokugqithisileyo
