Vutivi lebyi tirhaka bya tivalvu

Masungulo ya valve
1. Tipharamitha ta xisekelo ta valve i: ntshikelelo wa vito PN na dyayimeta ya vito DN
2. Ntirho wa xisekelo wa valve: tsema xitirhisiwa lexi hlanganisiweke, lulamisa mpimo wa ku khuluka, ivi u cinca ndlela leyi ku khulukaka ha yona
3, tindlela letikulu ta ku hlanganisiwa ka valve i: flange, thread, welding, wafer
4, ntshikelelo wa valve —— mpimo wa mahiselo wu kombisa leswaku: switirhisiwa swo hambana, mahiselo yo hambana yo tirha, mpimo lowukulu lowu pfumeleriweke ku hava ntshikelelo wo tirha wa nkucetelo wu hambanile
5. Kuna maendlelo mambirhi lamakulu ya flange standard: European state system na American state system.
Swihlanganisi swa ti pipe flange swa tisisiteme letimbirhi swihambanile hiku hetiseka naswona aswinga ringanisiwi;
Swi fanerile swinene ku hambanyisa hi mpimo wa ntshikelelo:
Endlelo ra mfumo ra le Yuropa 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;
Sisiteme ya mfumo wa le United States i PN1.0 (CIass75), 2.0 (CIass150), 5.0 (CIass300), 11.0 (CIass600), 15.0 (CIass900), 26.0 (CIass1500), 42.0 (CIass2500) MPa.
Tinxaka letikulu ta flange ya tiphayiphi i: integral (IF), plate flat welding (PL), neck flat welding (SO), neck butt welding (WN), socket welding (SW), screw (Th), butt welding ring loose sleeve (PJ / SE) / (LF / SE), flat welding ring loose sleeve (PJ / RJ) na xifunengeto xa flange (BL), na swin’wana.
Muxaka wa vuandlalo byo pfalela flange ngopfu ngopfu wu katsa: full plane (FF), protrusion surface (RF), concave (FM) convex (M) surface, ring connection surface (RJ), na swin’wana.

Tivalvu leti tolovelekeke (leti tolovelekeke).
1. Z, J, L, Q, D, G, X, H, A, Y, S hi ku landzelelana ya khodi ya muxaka wa valve kombisa: valve ya gede, valve yo yima, valve ya throttle, valve ya bolo, valve ya phaphatani, valve ya diaphragm, valve ya plug, valve yo kambela, valve ya vuhlayiseki, valve yo hunguta ntshikelelo na valve yo humesa mati.
2, Khodi ya muxaka wa vuhlanganisi bya valve 1,2,4,6,7 hi ku landzelelana yi te: 1-thread ya le ndzeni, 2-thread ya le handle, 4-flange, 6-welding, 7-pair clip
3, Ndlela yo hundzisela ya khodi ya valve 9,6,3 hi ku landzelelana yi te: 9-gezi, 6-pneumatic, 3-turbine worm.
4, Khodi ya swilo swa miri wa valve Z, K, Q, T, C, P, R, V hi ku landzelelana yi te: nsimbi leyi hoxiweke ya grey, nsimbi leyi hoxiweke leyi nga malleable, nsimbi leyi hoxiweke leyi ductile, koporo na alloy, nsimbi ya khaboni, nsimbi leyi nga riki na swilo ya chromium-nickel nickel, nsimbi leyi nga riki na swilo swa chromium-nickel-molybdenum, nsimbi leyi nga riki na swilo swa chromium-nickel-molybdenum, nsimbi ya chromium-molybdenum vanadium.
5, Seat seal kumbe lining khodi R, T, X, S, N, F, H, Y, J, M, W hi ku landzelelana: austenitic nsimbi leyi nga riki na swilo, koporo alloy, rhaba, pulasitiki, nayiloni pulasitiki, fluorine pulasitiki, Cr nsimbi leyi nga riki na swilo, hard alloy, lining rhaba, moner alloy, valve miri swilo.

6. Hi swihi swilo swinharhu leswikulu leswi faneleke ku tekeriwa enhlokweni loko ku hlawuriwa xitirhisiwa xo tirha?
1) Vuhumelerisi bya actuator byi fanele ku va byikulu ku tlula ndzhwalo wa valve yo lawula naswona byi fanele ku fambelanisiwa hi ndlela leyi twalaka.
2) Ku kambela nkatsakanyo wa ntolovelo, ku hambana ka ntshikelelo loku pfumeleriwaka loku boxiweke hi valve yo lawula ku fikelela swilaveko swa phurosese. Matimba lawa yanga ringaniseriwangiki ya valve core yafanele ku hlayiwa hinkarhi wa ku hambana lokukulu ka ntshikelelo.
3) Loko rivilo ro hlamula ra xitirhisiwa ri fikelela swilaveko swa ntirho wa phurosese, ngopfungopfu xitirhisiwa xa gezi.
7, TWS valve khamphani yi nga nyika valve yi na?
Valve ya phaphatani leyi tshameke hi rhaba: wafer phaphatani valve, lug phaphatani valve, .valve ya phaphatani ra flange; valve ya gede; valve yo kambela;valve yo ringanisela, valve ya bolo, na swin’wana.
Eka Tianjin Tanggu Water Seal Valve Co., Ltd., hi tinyungubyisa hi ku nyika switirhisiwa swa xiyimo xo sungula leswi fikelelaka swiyimo swa le henhla swa indasitiri. Hi nxaxamelo wa hina wo anama wa tivalvu na switirhisiwa, u nga hi tshemba ku nyika ntlhantlho lowu hetisekeke eka sisiteme ya wena ya mati. Tihlanganisi na hina namuntlha ku dyondza swo tala hi switirhisiwa swa hina na ndlela leyi hi nga ku pfunaka ha yona.
