Okokuqala, injongo yevalve yonyawo:
Ivalve yonyawo yivalve yokonga amandla.Ngokuqhelekileyo ifakelwa kwiNqanawa ekupheleni kombhobho wokufunxa ophantsi kwamanzi wempompo yamanzi.Ithintela ukubuyiswa kolwelo kumbhobho wempompo yamanzi kumthombo wamanzi, kwaye idlala umsebenzi wokungena kuphela nokungangeni.Zininzi iimveliso zokungenisa amanzi kunye neembambo zokuqinisa kwikhava yesivalo.Kunzima ukuvaleka, kwaye kusetyenziswa ngokusisiseko kwimibhobho yokumpompa, uthungelwano lwamanzi lukwagcina.Umgangatho une-single-lobe, i-double-lobe, kunye neentlobo ze-lobe ezininzi.Kukho amakhonkco e-flange kunye namakhonkco anemisonto.
Ivalve yeNyawo yenziwe ngumzimba wevalvu, idiski yevalvu, isigqubuthelo sevalvu, i-bushing, iringi yokutywina kunye namanye amalungu.Jonga umfanekiso ongezantsi ngeenkcukacha.Amanzi aphuma kumthombo wamanzi aya kumzimba wevalve yonyawo ukusuka kwisigqubuthelo sevalve yonyawo.Uxinzelelo kumbhobho wokuphuma ngasemva uya kuvala ngokukhawuleza i-valve flap, kwaye ulwelo aluyi kugalelwa kwakhona kumthombo wamanzi, odlala indima yokumpompa okugudileyo kunye nokugcina ukulahleka kwamandla kwamanzi.
Okwesibini, imiyalelo yofakelo lwevalve yoNyawo:
3. 1. Ukuze kuthintelwe ukubuya kwe-medium, i-valve yokukhangela kufuneka ifakwe kwisixhobo, izixhobo kunye nemibhobho.
2. Ivalve yokutshekisha ngokuqhelekileyo ifanelekile kwi-medium ecocekileyo, ayifanelekanga kwi-medium equkethe amaqhekeza aqinileyo kunye ne-viscosity ephezulu;
3. Ngokuqhelekileyo, iivalvu zokukhangela ukuphakamisa okuthe nkqo kufuneka zisetyenziswe kwimibhobho ethe tye kunye nobubanzi obuyi-50mm.
Ukufakela ingqalelo kunye nokugcinwa
1. Qinisekisa ukuba umzimba wevalvu ufakwe ngokuthe nkqo eNyaweni lombhobho wokufunxa wempompo yamanzi,
2. Emva kokuba umbhobho wokufunxa uzaliswe ngamanzi, uqala ngokukhawuleza, okukhokelela kwimo ye-semi-vacuum kumbhobho wokufunxa, kwaye amanzi afunxa kumbhobho othe nkqo ukugqiba inkqubo yokumpompa.
ukulungiswa kwakhona
1. Ukuze ukwandise ubomi benkonzo yevalve esezantsi, nikela ingqalelo ekujongeni imbonakalo yomzimba wevalve kwaye uthathe amanyathelo ahambelanayo ngexesha.
2. I-valve ephantsi ifumaneka kunye okanye ngaphandle kwentwasahlobo.Uninzi lwee-valve zendlela enye zinentwasahlobo, kodwa intwasahlobo ihlala ithambile kwaye ukuchasana nokuhamba kungahoywa.Ngokuqhelekileyo iivalvu zendlela enye ezinoxinzelelo lokuvula ngaphezulu kwe-0.3 MPa ziya kuphawulwa ngemithombo kwi-hydraulic schematic.
3. Ububanzi beemveliso eziveliswe yi-HONGKE VALVE zivela kwi-3/4 intshi-8 intshi.Nceda ubonise inombolo yemodeli xa uthenga.
