Iimfuno ngokubanzi zokufakelwa kweevalvu zamanzi olwandle

Indawo yofakelo lwevalvu kufuneka icwangciswe embindini kwicala elinye lendawo yesixhobo, kwaye iqonga lokusebenza eliyimfuneko okanye iqonga lokulungisa kufuneka linikezelwe.Iivalvu ezifuna ukusebenza rhoqo, ukugcinwa kunye nokutshintshwa kufuneka zibekwe phantsi, iqonga, okanye ileli. efikeleleka lula.Ukuphakama phakathi kombindi we-valve handwheel kunye nomgangatho osebenzayo uphakathi kwe-750-1500mm, ubude obufanelekileyo yi-1200mm, kunye nokuphakama kofakelo lwevalve engadingi ukusebenza rhoqo kunokufikelela kwi-1500-1800mm.Ivalve kufuneka igcinwe kumgama ochanekileyo ukusuka kwizibuko lokudosa ukuphepha ukubola okubukhali kwemigodi okubangelwa kukusebenza okuqinileyo kwearhente yendawo.

Ivalve enkulu

Umthwalo womzimba we-valve enkulu mkhulu, umbhobho kufuneka ulungelelaniswe ngokuthe tye kwaye uxhaswe ngokwahlukileyo, kwaye indawo yokusebenza kunye nokugcinwa kwendlela yokuhambisa kufuneka ithathelwe ingqalelo, kwaye izibiyeli kufuneka zifakwe kwelinye okanye kumacala omabini omatshini wokuhambisa.I-bracket ayifanele ifakwe kwipayipi emfutshane efuna ukuchithwa ngexesha lokugcinwa, kwaye akufanele ichaphazele ukuxhaswa kombhobho xa i-valve isusiwe, kwaye inkxaso kufuneka ibe yi-50-100mm ngaphezu komhlaba.Xa i-actuator inzima, inkxaso eyahlukileyo kufuneka ibonelelwe kuyo.Indlela yofakelo lweivelufa butterflyimiselwa ngokoyilo lwemibhobho.Xa umbhobho ulungiselelwe ngokuthe tye, iivelufa butterflyIsiqu kufuneka sicwangciswe ngokuthe tye kangangoko kunokwenzeka, kunye nolwalathiso lokuvulaivelufa butterflykufuneka zigcinwe zihambelana necala lokuhamba kwesixhobo ukuthintela uludaka kunye nezingcolisi eziphakathi ukuba zingangeni kwishafu yevalvu kunye nenxalenye yokutywina yevalve yomzimba.Xa i-valve ivuliwe, i-torque esebenzayo incinci, kwaye idlala indima yokukhupha umbhobho ukuya kwinqanaba elithile.

Iivalve yokujonga iwafericwangciswe kwindawo yokuphuma yempompo yamanzi olwandle, ilandelwa yivalve yokuvala.Ukuze uthintele ukungqubana kunye nokuphazamiseka phakathi kweepleyiti zevalve yeevalvu ezimbini ezisicaba, icandelo lombhobho othe ngqo kufuneka limiselwe phakathi kweevalvu ezimbini.Ubude becandelo lombhobho elithe tye (1.5-2.0 ) DN.Ukuba uhlobo lwebhabhathane olulungiselelwe ngokuthe tyeivalve yokujonga iwaferisetyenzisiwe, i-valve stem kufuneka ifakwe ngokuthe nkqo, enokwandisa ubomi benkonzo yevalve.Ukuba enye ukuya-ivalve yokukhangela ibambaokanye idiskhi enye-indlela ezimbini zentsimbi ukuyaivalve yokukhangela ibambaisetyenziswa, indlela yofakelo ivelufa kufuneka ixhase indlela yokuvala umxhuzulane.
