Hlola ama-valvekufanele kufakwe kumishini, kumadivayisi kanye namapayipi ukuze kuvinjwe ukuphikisana okuphakathi nendawo.
Ingcindezi encane yokuvula i-valve yokuhlola yi-0.002-0.004mpa.
Hlola ama-valvengokuvamile zilungele ukuhlanza imidiya, hhayi imidiya equkethe izinhlayiya eziqinile kanye ne-viscosity ephezulu.
Ii-valve yonyawongokuvamile ifakwa epayipini elime mpo le-pump inlet, futhi okuphakathi kugeleza ukusuka phansi kuye phezulu.
Uhlobo lokuphakamisa lunokusebenza okungcono kakhulu kokuvala kunohlobo lokushwiba, futhi linokumelana okukhudlwana koketshezi.Uhlobo oluvundlile kufanele lufakwe epayipini elivundlile, futhi uhlobo olume mpo kufanele lufakwe epayipini eliqondile.
Isikhundla sokufakwa kwe-valve yokuhlola i-swing ayinqunyelwe.Ingafakwa kumapayipi avundlile, aqondile noma athambekele.Uma efakwe kumapayipi aqondile, isiqondiso sokugeleza se-medium kufanele sisuke phansi siye phezulu.
Swayipha ama-valve okuhlolaakufanele enziwe ama-valve ama-caliber amancane, futhi angenziwa abe yingcindezi ephezulu yokusebenza.Ukucindezela okuzisholo kungafinyelela ku-42 MPa, futhi ububanzi obujwayelekile bungaba bukhulu, bufinyelele ku-2000 mm.Ingasetshenziswa kunoma iyiphi indawo yokusebenza nanoma yiluphi uhla lokushisa olusebenzayo ngokuya ngezinto zegobolondo nophawu.Okumaphakathi ngamanzi, isitimu, igesi, indawo edlayo, uwoyela, umuthi, njll. Izinga lokushisa elisebenzayo lendawo liphakathi - 196 - 800 C.
I-valve yokuhlola i-Swing ifanele ukucindezela okuphansi kanye ne-caliber enkulu, futhi ukufakwa kwayo kunqunyelwe.
Indawo yokufaka i-valve yokuhlola i-wafer ayinqunyelwe.Ingafakwa epayipini elivundlile noma epayipini eliqondile noma elithambekile.
Ama-valve okuhlola amabholaafanele amapayipi okucindezela okuphakathi nendawo futhi angenziwa abe yizinga elikhulu.
Impahla yegobolondo ye-valve yokuhlola ibhola ingenziwa ngensimbi engagqwali, futhi indawo engenalutho yophawu ingasongwa ngamapulasitiki obunjiniyela be-PTFE.Ngakho-ke, ingasetshenziswa futhi kumapayipi wemidiya evamile egqwalayo.Izinga lokushisa elisebenzayo liphakathi kuka-101 - 150 C, ingcindezi yokulinganisa ingaphansi kuka-4.0 MPa, futhi ububanzi bokudlula okujwayelekile buphakathi kwe-DN200 - DN1200.
Hlola ama-valvekufanele ilingane ngokufanele.Abahlinzeki bamavalvu kufanele banikeze idatha yosayizi abakhethiwe ukuze bathole usayizi wamavalvu lapho evuleke ngokugcwele ngenani elinikeziwe lokugeleza.
Ngengcindezi ephezulu nephakathihlola ama-valvengaphansi kwe-DN50mm,ama-valve okuhlola ama-liftfuthi ngokusebenzisaphakamisa ama-valve okuhlolakufanele kukhethwe.
Ngengcindezi ephansihlola ama-valvengaphansi kwe-DN50mm,ama-valve okuhlola ama-waferfuthiama-valve okuhlola ama-liftkufanele kukhethwe.
Ngengcindezi ephezulu nephakathihlola ama-valvene-DN engaphezu kuka-50 mm nangaphansi kuka-600 mm,ama-valve wokuhlola jikakufanele kukhethwe.
Ngengcindezi ephakathi nendawo nephansihlola ama-valvenge-DN enkulu kuno-200 mm nangaphansi kuka-1200 mm, ayigqokiama-valve okuhlola ibholakufanele kukhethwe.
Ngengcindezi ephansihlola ama-valvene-DN engaphezu kuka-50 mm nangaphansi kuka-2000 mm,ama-valve okuhlola ama-waferkufanele kukhethwe.
Emapayipini adinga isando samanzi esingaphansi noma angabikho lapho evala, ivalvu yokuhlola ukushwibeka evala kancane kufanele kukhethwe.
