Ukufakelwa kweiivalve zesango
Ivalve yesango, ekwabizwa ngokuba yivalve yesango, kukusetyenziswa kwesango ukulawula ukuvuleka nokuvalwa kwevalve, ngokuguqula icandelo elinqamlezayo ukulungelelanisa ukuhamba kwemibhobho kunye nokuvula nokuvala umbhobho.Iivalvu zesango zisetyenziselwa ubukhulu becala kumbhobho wokuvula ngokupheleleyo okanye ukusebenza ngokuvalelekileyo kwesiphakathi solwelo.Ufakelo lwevalvu yesango ngokuqhelekileyo akukho mfuneko yendlela, kodwa ayikwazi ukufakwa phezulu.
Ukufakelwa kweivalve yeglowubhu
Ivalve yeglowubhu kukusetyenziswa kwediski ukulawula ukuvulwa nokuvalwa kwevalve.Ngokutshintsha i-gap phakathi kwe-disc kunye nesihlalo, oko kukuthi, ukutshintsha ubungakanani becandelo leshaneli ukulungelelanisa ukuhamba okuphakathi okanye ukunqumla indlela ephakathi.Ingqalelo kufuneka ihlawulwe kwicala lokuqukuqela ngakulo xa kufakwa iivalvu zeglowubhu.
Umgaqo omawulandelwe xa kufakwa ivalve yeglowubhu kukuba ulwelo olukumbhobho ludlula kumngxuma wevalve ukusuka ezantsi ukuya phezulu, ngokuqhelekileyo owaziwa ngokuba “phantsi ukuya phezulu”, kwaye aluvumelekanga ukuba lufakwe umva.
Khangela ivalveukufakela
Ivalve yokukhangela, eyaziwa ngokuba yi-valve yokukhangela, ivalve yokukhangela, ivalve phantsi koxinzelelo loxinzelelo ngaphambi nangemva kokuba ivalve ivule kwaye ivalwe ngokuzenzekelayo, indima yayo kukwenza i-medium kuphela isalathiso sokuhamba, kunye nokuthintela ukuhamba okuphakathi emva.Ivalve yokukhangela ngokwesakhiwo sayo esahlukileyo, kukho ukuphakamisa, ukujingi kunye nohlobo lwe-butterfly wafer.Ukuphakamisa i-valve yokukhangela kunye neendawo ezithe tye kunye nezithe nkqo.Khangela ufakelo lwevalvu, kwakhona kufuneka ingqalelo ukuhamba okuphakathi, ayikwazi ukufakwa umva.
Ukufakelwa kweivalve yokunciphisa uxinzelelo
Ivalve yokunciphisa uxinzelelo ihlengahlengiswa ukunciphisa uxinzelelo lokungena kuxinzelelo lokuphuma olufunekayo, kwaye uthembele kumandla ophakathi ngokwawo, ukuze uxinzelelo lokuphuma lugcine ngokuzenzekelayo ivalve ezinzile.
Ukusuka kwimbono ye-fluid mechanics, i-valve yokunciphisa uxinzelelo yi-valve yokuchasana kwendawo inokutshintsha i-throttle element, oko kukuthi, ngokutshintsha indawo ye-throttle, izinga lokuhamba kunye nokutshintsha kwamandla e-kinetic, okukhokelela ekulahlekeni koxinzelelo oluhlukeneyo, ukuze kufezekiswe. injongo yoxinzelelo.Emva koko uthembele kulawulo kunye nohlengahlengiso lwenkqubo yolawulo, ukuze i-valve yoxinzelelo lwe-fluctuation kunye ne-spring force balance, ukuze i-valve yoxinzelelo kuluhlu oluthile lwempazamo ukugcina rhoqo.
1. Iqela levalve yokunciphisa uxinzelelo elifakwe ngokuthe nkqo licwangciswe ngokubanzi eludongeni kumphakamo ofanelekileyo ukusuka emhlabeni;Iiseti zevalvu yoxinzelelo oluthe tyaba zixhonywe ngokuthe tyaba kwiqonga lokusebenza elisisigxina.
2. Ukusetyenziswa kwentsimbi ngokulandelanayo kwiivalve ezimbini zokulawula (ezihlala zisetyenziselwa i-valve yeglobhu) ngaphandle kwodonga, ukwenza i-bracket, i-bypass pipe iphinde ifakwe kwi-bracket, ukulinganisa kunye nokulungelelanisa.
3. Ivalve yokunciphisa uxinzelelo kufuneka ifakwe ngokuthe nkqo kumbhobho othe tye, ingathotywanga, utolo olukumzimba wevalvu kufuneka lwalathe kwicala lokuhamba okuphakathi, lungafakwanga.
4. I-valve yokumisa kunye ne-high and low pressure gauge gauge kufuneka ifakwe kumacala omabini ukujonga utshintsho loxinzelelo ngaphambi nangemva kwevalve.Idayamitha yombhobho emva kwevalve yokunciphisa uxinzelelo kufuneka ibe yi-2#-3# inkulu kunedayamitha yombhobho wokungena phambi kwevalve, kwaye ufakele umbhobho wokugqitha kulondolozo.
5. Umbhobho wokulinganisa uxinzelelo we-valve yokunciphisa uxinzelelo lwefilimu kufuneka uxhunywe kumbhobho ophantsi.Ivalve yokhuseleko kufuneka imiselwe umbhobho woxinzelelo oluphantsi ukuqinisekisa ukusebenza ngokukhuselekileyo kwenkqubo.
6. Xa isetyenziselwa ukuchithwa kwe-steam, umbhobho wokukhupha kufuneka ubekwe.Kwiinkqubo zemibhobho ezifuna iqondo eliphezulu lokucocwa, isihluzi kufuneka sibekwe phambi kwevalve yokunciphisa uxinzelelo.
7. Emva kokufakwa kweqela le-valve yokunciphisa uxinzelelo, uvavanyo loxinzelelo, ukuhlamba kunye nohlengahlengiso kufuneka lwenziwe kwi-valve yokunciphisa uxinzelelo kunye ne-valve yokukhusela ngokweemfuno zoyilo, kwaye uphawu oluhlengahlengisiweyo kufuneka lwenziwe.
Xa ugungxula ivalve yokunciphisa uxinzelelo, vala ivalve yokungena yevalve yokunciphisa uxinzelelo kwaye uvule ivalve yokugungxula ukuze ugungxule.
