Telescopic Flange Npauj Npaim Valve yog dab tsi
Lub flange telescopic npauj npaim valve yog npauj npaim valve uas sib txuas flange kev twb kev txuas thiab telescopic muaj nuj nqi. Nws cov qauv tsim tseem ceeb yog txhawm rau txhawm rau txhawm rau txhawm rau hloov pauv axial ntawm cov raj xa dej los ntawm thermal expansion thiab contraction, installation yuam kev lossis nruab nrab siab hloov pauv los ntawm cov qauv telescopic flange, thaum siv cov kev sib hloov ntawm tus npauj npaim phaj kom paub qhov qhib thiab kaw thiab kev tswj ntawm cov kua dej.
Cov yam ntxwv zoo
Flanged Connection Design: Lub cev lub cev muaj flanges ntawm ob qho kawg, uas ncaj qha txuas rau cov yeeb nkab flanges ntawm bolts. Qhov no ua kom ntseeg tau tias kev sib khi ruaj khov thiab kev teeb tsa yooj yim, ua rau nws tshwj xeeb tshaj yog haum rau siab - siab thiab loj - daim ntawv thov txoj kab uas hla. Cov khoom flange feem ntau yog cam khwb cia hlau, carbon steel, los yog stainless hlau, txuam lub valve lub cev cov ntaub ntawv los xyuas kom meej tag nrho lub zog thiab corrosion kuj.
Expansion/Retraction Structure:
Lub tes tsho- hom Expansion/Retraction: Lub cev valve muaj ob lub tes tsho hauv nruab nrab. Lub tes tsho sab hauv swb nyob rau hauv lub tes tsho sab nraud, ua tiav kev sib khi zoo los ntawm cov nplhaib sib khi (xws li O-rings lossis di ncauj seals).
Belled Pipe-hom Expansion/Retraction: Ib lub tshuab nqus hlau txuas ob qhov kawg ntawm lub cev valve. Kev tshem tawm yog absorbed los ntawm elastic deformation ntawm lub hauv siab, haum rau siab - kub thiab siab - ib puag ncig siab.
Limiting thiab Locking Devices: txwv bolts lossis blocks yog muab rau ntawm ob qho kawg ntawm lub tes tsho nthuav dav kom tiv thaiv kev nthuav dav thiab kev cog lus uas tuaj yeem ua rau kev sib khi tsis ua haujlwm. Qee cov qauv tau nruab nrog lub nplhaib xauv los txhim kho lub tes tsho txoj haujlwm thaum lub sijhawm teeb tsa thiab tiv thaiv kev hloov pauv thaum lub sijhawm ua haujlwm.
Npauj Npaim Phaj thiab Sealing System:
Soft Seal: Elastic cov ntaub ntawv xws li nitrile roj hmab thiab EPDM muab kev sib khi zoo tab sis muaj qhov kub thiab txias tsis kam (tsawg dua lossis sib npaug li 120 degree). Hard Foob: Lub rooj zaum valve thiab npauj npaim phaj sealing qhov chaw yog overlayed nrog stainless hlau los yog cobalt-raws li nyuaj alloy, muab kub thiab siab tsis kam thiab lub neej ntev kev pab cuam.
Composite Foob: Kev sib xyaw ua ke ntawm cov ntaub ntawv mos thiab tawv tawv (xws li cov graphite saj zawg zog phaj ua ke nrog stainless hlau phaj), sib txuas elasticity thiab hnav tsis kam.
Npauj Npaim Phaj Tsim: Ib lub voj voog lossis elliptical nyias phaj uas tig ib ncig ntawm nws tus kheej axis (0℃~ 90 degree) los tswj kev ntws. Cov ntaub ntawv muaj xws li cov hlau tsis muaj steel, tooj liab, nylon, lossis roj hmab txheej, yoog raws cov xov xwm sib txawv.
Sealing Forms:
Eccentric Structure: Ob chav eccentric tsim txo kev sib txhuam thiab txuas ntxiv lub neej kev pab cuam; triple eccentric qauv kiag li tshem tawm kev sib txhuam, haum rau ultra- kub thiab kub siab.
Functional Advantages
Pipeline Stress Compensation: Absorbs axial displacement los ntawm qhov kub thiab txias hloov pauv, kev hloov pauv hauv xov xwm, lossis kev teeb tsa tsis raug, txo qhov kev pheej hmoo ntawm cov raj xa dej deformation thiab tiv thaiv kev tawg lossis tawg. Kev nthuav dav / kev sib cog lus feem ntau yog 1% ~ 3% ntawm cov kab yeeb nkab nominal, ua tau raws li qhov xav tau ntawm kev ua haujlwm feem ntau.
Kev tswj cov kua dej muaj txiaj ntsig zoo: 90℃kev sib hloov ntawm tus npauj npaim phaj ua tiav tag nrho qhib lossis kaw, muab kev pib sai- nce thiab kaw nrog lub zog ua haujlwm qis, tsim nyog rau cov xwm txheej uas yuav tsum tau txiav tawm sai sai. Optimized flow channel tsim kom ntseeg tau tias cov dej ntws hauv nruab nrab, txo cov dej tsis kam thiab eddies, thiab txo qis zog noj.
Yooj yim installation thiab tu:
Flange kev sib txuas txhawb nqa kab rov tav lossis ntsug kev teeb tsa yam tsis muaj kev tshaj tawm cov kev taw qhia kev txwv, ua kom haum rau cov raj xa dej sib txawv.
Hloov cov ntsaws ruaj ruaj txhawb ntau dua 50,000 lub zog qhib thiab kaw lub voj voog nrog xoom xau, txo cov nqi kho.
Lub telescopic qauv tso cai rau lub valve lub cev kom luv luv, muab qhov chaw khiav hauj lwm rau disassembling nyob rau hauv lub Cheebtsam (xws li npauj npaim phaj thiab lub rooj zaum valve), txo cov pipeline disassembly.
Daim ntawv thov Scenario
Municipal Water Supply and Drainage: Siv nyob rau hauv nroog cov kav dej hauv nroog thiab cov kav dej phwj tuaj thiab cov kav dej tawm los tswj cov dej ntws thiab siab, thiab tswj cov kav dej. Lub telescopic muaj nuj nqi adapts mus rau pipeline expansion thiab contraction vim kub hloov, txo pipeline kev nyuaj siab thiab tiv thaiv rupture.
Chemical and Metallurgical Industries: Siv rau hauv cov khoom siv tshuaj tiv thaiv thiab cov kav dej kom tswj tau tus nqi ntws thiab feem ntawm cov khoom siv tshuaj, kom ntseeg tau cov tshuaj lom neeg zoo. Corrosion-cov ntaub ntawv tiv taus (xws li stainless hlau thiab fluoropolymer- cov ntaub ntawv hauv kab) tuaj yeem tiv taus cov xov xwm corrosive xws li cov kua qaub thiab alkalis, tiv thaiv cov xov xwm tawm thiab cov yeeb nkab thaiv.
Kev Lag Luam Hluav Taws Xob: Siv nyob rau hauv boilers thiab chav kav dej los tswj thiab tswj cov dej ntws thiab siab, ua kom muaj kev nyab xeeb ntawm boiler kev ua haujlwm thiab kev siv lub tshuab kom zoo. Lub expansion muaj nuj nqi absorbs thermal expansion ntawm chav pipelines vim kub hloov, tiv thaiv pipeline rupture.
Marine Engineering: Bidirectional sealing flange expansion npauj npaim li qub yog tsim rau bidirectional flow media scenarios xws li seawater desalination thiab thim rov qab osmosis systems, ua tiav xoom- leakage sealing.
Xaiv cov ntsiab lus
Nominal Diameter (DN) thiab Kev Ntsuas Siab (PN): Xaiv DN raws li cov kav dej loj kom ntseeg tau tias muaj qhov sib txuam; PN yuav tsum siab tshaj qhov ua haujlwm siab tshaj plaws los txiav txim siab txog dej rauj. Feem ntau DN: DN50 ~ DN3000; Feem ntau PN ntau: PN0.6 ~ PN16.
