2024-01-03 09:35:26 dr hab
Stainless hlau li qub tau siv dav hauv kev lag luam. Muaj ntau ntau hom thiab kev sib txuas. Yuav ua li cas tag nrho stainless hlau valve txuas nrog lub raj xa dej lossis cov khoom siv tsis tuaj yeem tsis quav ntsej. Stainless hlau li qub zoo li muaj kua khiav, xau, xau, thiab xau. Feem ntau ntawm lawv yog vim txoj kev sib txuas kom raug tsis raug xaiv.Cov hauv qab no qhia txog hom kev sib txuas ntawm stainless hlau valve.
1. Flange kev twb kev txuas
Flange kev twb kev txuas yog feem ntau siv daim ntawv txuas ntawm stainless hlau li qub thiab cov kav dej lossis cov khoom siv. Nws yog hais txog ib qho kev sib txuas uas tau muab tshem tawm uas flanges, gaskets thiab bolts txuas rau ib leeg raws li cov txheej txheem sib khi ua ke. Cov yeeb nkab flange yog hais txog cov flange siv rau cov kav dej hauv cov kav dej, thiab thaum siv cov khoom siv, hais txog qhov nkag thiab qhov hluav taws xob flange ntawm cov khoom siv. Flange kev sib txuas yog yooj yim siv thiab tuaj yeem tiv taus siab dua. Flange kev twb kev txuas tuaj yeem siv rau stainless hlau li qub ntawm ntau qhov ntau thiab tsawg thiab nominal pressures, tab sis muaj qee qhov kev txwv ntawm kev ua haujlwm kub. Nyob rau hauv qhov kub thiab txias, cov flange txuas bolts yog qhov yooj yim rau nkag thiab ua rau to. Raws li ib txwm muaj, kev sib txuas Flange raug pom zoo siv rau qhov kub thiab txias ≤350 ° C.
2. Threaded kev twb kev txuas
Qhov no yog ib txoj kev sib txuas yooj yim feem ntau siv rau ntawm cov hlau stainless me me li qub.
1) Direct sealing: Cov xov sab hauv thiab sab nraud ncaj qha ua cov ntsaws ruaj ruaj. Txhawm rau kom ntseeg tau tias qhov kev sib txuas tsis xau, cov roj lead, cov ntaub pua chaw thiab cov ntaub ntawv raw khoom feem ntau siv los sau nws.
2) Indirect sealing: Lub zog ntawm cov xov nruj yog xa mus rau lub gaskets ntawm ob lub dav hlau, tso cai rau cov gaskets ua raws li cov ntsaws ruaj ruaj.
3. Kev sib txuas ntawm vuam
Welded kev twb kev txuas yog hais txog ib hom kev twb kev txuas nyob rau hauv uas stainless hlau valve lub cev muaj ib tug vuam zawj thiab txuas nrog lub raj xa dej los ntawm vuam. Cov welded kev sib txuas ntawm stainless hlau li qub thiab cov kav dej tuaj yeem muab faib ua pob tw vuam (BW) thiab qhov (socket) vuam (SW). Stainless hlau valve taub qab vuam kev sib txuas (BW) tuaj yeem siv rau ntau qhov ntau thiab tsawg, qhov siab thiab qhov kub thiab txias; thaum lub qhov (socket) vuam txuas (SW) feem ntau haum rau stainless hlau li qub ≤DN50.
4. Daim npav lub tes tsho txuas
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm ferrule kev sib txuas yog tias thaum lub txiv ntseej nruj, lub ferrule nyob rau hauv siab, ua rau nws cov hniav tuaj rau ntawm phab ntsa ntawm cov yeeb nkab. Lub khob hliav qab sab nraud ntawm lub ferrule yog nyob rau hauv kev sib cuag nrog lub khob hliav qab nto hauv qhov sib koom ua ke nyob rau hauv siab, yog li ntseeg tau tias tiv thaiv kom tsis txhob xau. .Qhov zoo ntawm daim ntawv txuas no yog:
1) Me me, lub teeb yuag, qauv yooj yim, yooj yim rau disassemble thiab sib sau ua ke;
2) Kev sib txuas muaj zog, kev siv ntau yam, thiab tuaj yeem tiv taus siab (1000 kg / cm²), kub siab (650 ℃) thiab cuam tshuam kev co;
3) Ntau yam khoom siv tuaj yeem xaiv, haum rau kev tiv thaiv corrosion;
4) Cov txheej txheem ua kom raug tsis yog siab;
5) Yooj yim rau nruab ntawm qhov siab siab.
Tam sim no, daim ntawv txuas ferrule tau txais kev pom zoo hauv qee qhov me me-inch stainless hlau valve khoom hauv kuv lub tebchaws.
Qhov no yog txoj kev sib txuas ceev uas yuav tsum tau tsuas yog ob lub bolts thiab tsim nyog rau qhov tsis tshua muaj siab stainless hlau li qub uas nquag disassembled.
Internal self-tightening kev twb kev txuas yog ib hom kev sib txuas uas siv nruab nrab siab rau nws tus kheej-tightening. Qhov siab dua qhov nruab nrab, qhov ntau dua tus kheej-tightening quab yuam. Yog li ntawd, daim ntawv txuas no yog tsim rau high-pressure stainless hlau li qub. Piv nrog flange kev twb kev txuas, nws txuag tau ntau ntawm cov khoom thiab cov neeg ua haujlwm, tab sis nws kuj yuav tsum muaj qee yam preload quab yuam kom nws tuaj yeem siv tau zoo thaum lub siab hauv lub valve tsis siab. Stainless hlau li qub ua los ntawm tus kheej-tightening sealing cov ntsiab lus yog feem ntau high-pressure stainless hlau li qub.
Muaj ntau ntau lwm daim ntawv txuas rau stainless hlau li qub. Piv txwv li, ib co me me stainless hlau li qub uas tsis tas yuav dismantled yog welded rau cov kav dej; qee qhov tsis-hlau stainless hlau li qub siv cov qhov (socket) txuas, thiab lwm yam. Cov neeg siv cov hlau stainless li qub yuav tsum kho lawv tshwj xeeb raws li qhov xwm txheej tiag tiag.
