Kev ua kom raug thiab xaiv cov li qub thiab cov pipelines yog qhov tseem ceeb hauv kev lag luam ntau lawm, cov dej hauv nroog thiab tso dej, thiab kev thauj mus los hauv lub zog. Kev Xaiv Kev Tshawb Fawb kom paub meej cov txheej txheem ruaj khov, txhim kho kev ua tau zoo, thiab txo cov nqi txij nkawm thiab kev phom sij kev nyab xeeb. Hauv qab no, peb piav ntau ntxiv rau cov ntsiab lus tseem ceeb rau kev xaiv valve thiab xa hluav taws xob, txhawb nqa los ntawm kev kawm txog cov qauv tshwj xeeb.
I. Core Xaiv cov kev xaiv
1. Pipeline Parameter Compatibility
- Nominal Inch (DN) txuam
Valve DN yuav tsum ua kom haum nrog raj xa dej hauv lub taub hau sab hauv kom ua kom cov kua dej du. Cov kev qhia tshwj xeeb ntau ntawm DN15 (½ nti) rau dn2000.
Tus yam ntxwv: Rau DN50 cov raj xa dej hauv cov dej ua vaj tsev, siv aZ41h {1}} C-DN50 rooj vag Valve:
"Z" {{{= rooj vag valve, "41 {{{{{{{{{{{{8} {8} {8} {8} {8} {{8} {8} {8} {{8} {8} {8} {{8} {
- Kev Ntsuas Siab (PN)
Xaiv PN raws raws cov raj xa dej ua haujlwm siab nrog 1.1-1.5x kev nyab xeeb ntawm kev nyab xeeb.
Tus yam ntxwv: Rau ib tug 4. {{{0 mpa mpa roj av pipeline, siv pn6.3 lossis pn10 li qub, xws liQ347F {-16 p-dn100 pob valve:
"Q" {{= pob lub pob valve, "347" {{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{{
- Cov khoom siv tau sib xws
Valve thiab xa dej yuav tsum tawm tsam corrosion thiab kov cov kev xav tau.
Tus yam ntxwv: Sus304 stainless hlau zaub mov-qib pipelines xav tau sus304 li qub. Titanium Alloy Pipelines nyob rau hauv cov tshuab xav tau cov tshuab titanium alloy li qubD371ti {{1} Dn300 Npauj Npaim Valve:
"D" {{{{{{0}}} {{{{{{{= 1. 0 mpa.
2. Cov Qha Tsiaj Tshaj
- Media Media
Corrosive kua (piv txwv li, sulfuric acid): Siv cov tshuaj fluorine-lined zoo liJ41f 46-16 C-DN80(FEP-kab).
Flammable media (piv txwv li, roj \/ roj): Hluav Taws-nyab xeeb li qub (piv txwv li,Z41F-25C, Raws li API 607).
Slurry Media: Riam Rooj Vag Cov Nqi (piv txwv li,Sdz673x -10- dn200) Nrog cov tshuab roj hmab los tiv thaiv txhaws.
- Qho so
Cryogenic (-46 degree):Q41F {{{} p-lcb(Tsawg-kub cov roj carbon hlau).
Kev kub-kub (550 degree):Z41h {1}} i-dn150(Cr-mo alloy steel nrog nyuaj-raced ntsaws ruaj).
- Viscosity
High-viscosity (piv txwv li, asphalt):Q947F {{{1} dn200 v-chaw nres nkoj pob valverau shear muaj peev xwm.
Tsawg-viscosity (piv txwv li, dej):D941x -10- dn500 Muag muag npauj npaim valverau kev ntws tsis kam.
3. Yuav Tsum Tau Ua
- Muab cais nyob ib leeg: Rooj vag li qub (piv txwv li,Z41H-16C) Rau tag nrho-qhib \/ kaw scararios.
- Ntws Tswj: Lub ntiaj teb li qub (piv txwv li,J41H-25) rau kev kho kom haum.
- Kuaj cov nuj nqi: VIAV TXAWJ QAIB (piv txwv li,H44H-16C) rau kab rov tav Pipelines.
4. Txhim kho & ua haujlwm
- Chaw Cuam Tshuam: Mine wafer li qub (piv txwv li,D71X-10) lossis txuas ntxiv cov qia li qub (piv txwv li,Z41T -10-} jg).
- Kev ua yeeb yam: Phau ntawv (piv txwv li,J11W-16T) Rau kev yooj yim; Fais (piv txwv li,Z941h -25- dn300) Rau Automation.
5. Cov Lus Qhia Tshwj Xeeb
- Kev Nyab Xeeb Kev Nyab Xeeb: Li qub zoo liD343H-25CNrog hlau ntsaws ruaj ruaj thiab graphite gaskets (API 607 ua raws li).
- Anti-static: Q41F {-16 p-liRau cov pa roj av, featuring springs.
- Puas ua: Cov ntoo khaub zig (piv txwv li,U41tc -10- dn150) Rau cov ntoo slurry.
Ii. Kev Thov Thov Thov
- Cov khoom hauv nroog dej (DN8 0 0, 0.8 mpa):
Ib lub pa:Z45X -10- dn800(Tuam Tshoj hlau, hluav taws xob \/ txhais tes dual drive).
- Roj Refinery (DN300, 2.5 MPa, 280 Qib):
Ib lub pa:Q947F {{1} Dn300 V-Chaw nres nkoj Pob Valve(WCB lub cev, carbide-coated).
- Roj Pipeline (DN1200, 10 MPA):
Ib lub pa:Q61F -100- dn1200(Welded, L360Qs tiv thaiv cov neeg Sulphur hlau).
- Chav pipeline (DN500, 300 degree):
Ib lub pa:D343h {1}} C-DN500(triple eccentric, 12crmov alloy).
III. Qhov Yuam Kev Ua Tau Zoo & Kev Txhim Kho
- Yuam:
Siv cov roj carbon hlau li qub hauv dej hiav txwv (nrawm corrosion).
Undersized kev ntsuas siab (piv txwv li, pn1.6 rau 2. {{{}} Mpa mpa).
- Cov kev daws teeb meem:
Tsim cov ntaub ntawv xaiv nrog cov ntaub ntawv kawm.
Siv kev sim CFD rau kev ua kom txaus siab.
