Ulwazi olusebenzayo lweevalvu

Isiseko seValve
1. Iiparameter ezisisiseko zevalvu zezi: uxinzelelo oluqhelekileyo lwe-PN kunye nobubanzi obuqhelekileyo be-DN
2. Umsebenzi osisiseko wevalvu: nqumla i-medium edibeneyo, lungisa isantya sokuhamba kwamanzi, kwaye utshintshe indlela yokuhamba kwamanzi
3, iindlela eziphambili zokudibanisa ivalvu zezi: i-flange, intambo, ukuwelda, i-wafer
4, uxinzelelo lwevalvu —— inqanaba lobushushu libonisa ukuba: izixhobo ezahlukeneyo, amaqondo obushushu ahlukeneyo okusebenza, uxinzelelo oluphezulu oluvumelekileyo olungenampembelelo lwahlukile
5. Kukho iinkqubo ezimbini eziphambili zomgangatho weflange: inkqubo yelizwe laseYurophu kunye nenkqubo yelizwe laseMelika.
Uqhagamshelo lweflange yepayipi yeenkqubo ezimbini zahlukile ngokupheleleyo kwaye azinakulinganiswa;
Kungcono kakhulu ukwahlula ngokwenqanaba loxinzelelo:
Inkqubo yelizwe laseYurophu yiPN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa;
Inkqubo yelizwe lase-US yi-PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
Iintlobo eziphambili zeflange yepayipi zezi: i-integral (IF), i-plate flat welding (PL), i-neck flat welding (SO), i-neck butt welding (WN), i-socket welding (SW), i-screw (Th), i-butt welding ring loose sleeve (PJ / SE) / (LF / SE), i-flat welding ring loose sleeve (PJ / RJ) kunye ne-flange cover (BL), njl.
Uhlobo lomphezulu wokutywina weFlange lubandakanya ikakhulu: i-full plane (FF), i-protrusion surface (RF), i-concave (FM) i-convex (M), i-ring connection surface (RJ), njl.

Iivalvu eziqhelekileyo (eziqhelekileyo)
1. Z, J, L, Q, D, G, X, H, A, Y, S ngokulandelelanayo kwekhowudi yohlobo lwevalvu ibonisa: ivalvu yesango, ivalvu yokumisa, ivalvu yokuphuthuma, ivalvu yebhola, ivalvu yebhabhathane, ivalvu yediaphragm, ivalvu yeplagi, ivalvu yokujonga, ivalvu yokhuseleko, ivalvu yokunciphisa uxinzelelo kunye nevalvu yokukhupha amanzi.
2, Ikhowudi yohlobo loqhagamshelo lwevalvu 1, 2, 4, 6, 7 ngokulandelelana ithi: umsonto wangaphakathi o-1, umsonto wangaphandle o-2, i-flange e-4, i-welding e-6, ikliphu yezibini ezi-7
3, Imo yokudlulisela yekhowudi yevalvu 9,6,3 ngokulandelelana ithi: 9-electric, 6-pneumatic, 3-turbine worm.
4, Ikhowudi yezinto zomzimba wevalvu u-Z, K, Q, T, C, P, R, V ngokulandelelana uthe: intsimbi engwevu ephosiweyo, intsimbi ephosiweyo ethambileyo, intsimbi ephosiweyo ethambileyo, ubhedu kunye ne-alloy, intsimbi yekhabhoni, intsimbi engatyiwayo ye-chromium-nickel nickel, intsimbi engatyiwayo ye-chromium-nickel-molybdenum, intsimbi ye-chromium-molybdenum vanadium.
5, Ikhowudi yesitywina sesihlalo okanye yelayini R, T, X, S, N, F, H, Y, J, M, W ngokulandelanayo: intsimbi engagqwaliyo ye-austenitic, i-copper alloy, irabha, iplastiki, iplastiki ye-nylon, iplastiki ye-fluorine, intsimbi engagqwali ye-Cr, i-hard alloy, irabha yelayini, i-moner alloy, izinto zomzimba wevalvu.

6. Zeziphi izinto ezintathu eziphambili ekufuneka ziqwalaselwe xa kukhethwa i-actuator?
1) Isiphumo se-actuator kufuneka sibe sikhulu kunomthwalo wevalvu elawulayo kwaye kufuneka sihambelane ngokufanelekileyo.
2) Ukujonga indibaniselwano eqhelekileyo, umahluko ovumelekileyo woxinzelelo oluchazwe yivalvu elawulayo uyahlangabezana neemfuno zenkqubo. Amandla angalinganiyo engundoqo wevalvu kufuneka abalwe ngexesha lomahluko omkhulu woxinzelelo.
3) Ingaba isantya sokuphendula se-actuator siyahlangabezana neemfuno zokusebenza kwenkqubo, ingakumbi i-actuator yombane.
7, inkampani yevalvu yeTWS inokubonelela ngevalvu?
Ivalvu yebhabhathane ehleli ngerabha: ivalvu yebhabhathane ye-wafer, ivalvu yebhabhathane ye-lug,ivalvu yebhabhathane esisangqaivalvu yesango; ivalvu yokujonga;ivalvu yokulinganisela, ivalvu yebhola, njl.njl.
