fondasyon valv
1. bann paramet debaz sa valv i: presyon nominal PN e dyamet nominal DN
2. Fonksyon debaz sa valv: koup sa medyom konekte, aziste debi, e sanz direksyon koule
3, bann fason prensipal koneksyon valv i: bride, difil, soudwar, wafer
4, presyon valv —— nivo tanperatir i endike ki: diferan materyo, diferan tanperatir travay, presyon travay maksimonm ki ganny permet san lenpak i diferan
5. I annan de sistenm prensipal lo standar bride: sistenm leta Eropeen e sistenm leta Ameriken.
bann koneksyon bride tiyo sa de sistenm i konpletman diferan e pa kapab ganny matche;
i pli apropriye pou fer distenksyon par nivo presyon:
sistenm leta Eropeen i PN0.25,0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa;
Sistenm leta Lanmerik i PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
bann kalite prensipal bride tiyo i: entegral (IF), soudman plak plat (PL), soudman plat likou (SO), soudman likou (WN), soudman soket (SW), vis (Th), soudwar bout bag loose sleeve (PJ / SE) / (LF / SE), brans soudman plat loose sleeve (PJ / SE) / (LF / SE), flat welding bag loose sleeve (PJ / RJBL), eksetera (RJBL), ek kouvertir eksetera.
kalite sirfas sele bride i prensipalman enkli: plan plen (FF), sirfas protrusyon (RF), sirfas konveks konkav (FM), sirfas koneksyon bag (RJ), eksetera.
bann valv komen (komen)
1. Z, J, L, Q, D, G, X, H, A, Y, S respektivman kod kalite valv i endike: gate valve, stop valve, throttle valve, ball valve, butterfly valve, diaphragm valve, plug valve, check valve, safety valve, pressure reducing valve and drain valve.
2, Kod kalite koneksyon valv 1,2,4,6,7 respektivman ti dir: 1-fil entern, 2-fil ekstern, 4-brid, 6-soud, 7-per klip

5, Seat seal or lining code R, T, X, S, N, F, H, Y, J, M, W respektivman: austenitic stainless steel, copper alloy, rubber, plastic, nylon plastic, fluorine plastic, lining steel, hard alloy, lining rubber, moner alloy, valve body material.
6. Ki trwa fakter prensipal ki devret ganny konsidere dan seleksyon en actuator?
1) sorti sa aksyonner i devret pli gran ki load sa valv regilater e i devret rezonnabman matche.
2) pou tyek konbinezon standar, diferans presyon ki ganny spesifye par valv regilater i zwenn bann legzizans prosesis. lafors dezekilibre dan nwayo valv i devret ganny kalkile pandan sa gran diferans presyon.
3) Si vites repons sa aktyater i zwenn bann legzizans loperasyon prosesis, sirtou sa aktyater elektrik.
7, lakonpannyen valv TWS i kapab fourni sa valv i annan?
valv papiyon an lastik: wafer butterfly valve, lug butterfly valve,valv papiyon bride; valv baro; valv tyeke;valv balansman, valv boul, eksetera.
kot Tianjin Tanggu Water Seal Valve Co., Ltd., nou fyer pour fourni bann prodwi premye klas ki zwenn bann standar pli o dan lendistri. avek nou gran varyete valv ek fitting, ou kapab annan konfyans dan nou pou fourni solisyon parfe pou ou sistenm delo. kontakte nou ozordi pou aprann plis lo nou bann prodwi e ki mannyer nou kapab ed ou.
