Muaj ntau homnpauj npaim li qub, nrog rau kev txiav tawm sai thiab kev hloov kho tas li.Feem ntau yog siv rau cov kua thiab roj uas tsis tshua muaj siab loj-inch pipelines.Nws yog qhov tsim nyog rau lub sijhawm uas qhov kev xav tau poob siab tsis siab, kev hloov pauv yuav tsum tau ua, thiab qhov yuav tsum tau qhib thiab kaw nrawm;Feem ntau qhov kub thiab txias yog qis dua 300 ℃ thiab lub siab yog qis dua 40 kg (npaj npaim li qub feem ntau siv tsis tshua muaj siab, zoo li cov khoom siv hauv tsev. tsawg tsawg tuaj yeem ua tiav CL600), qhov nruab nrab feem ntau yog siv rau dej thiab roj, thiab qhov nruab nrab tsis xav tau, thiab granular nruab nrab kuj siv tau.
Raws li lub kaw lus npauj npaim valve, nws coj txoj kev loj hlob sai tom qab qhov tshwm sim ntawm cov roj hmab hluavtaws, yog li nws yog hom tshiab ntawm kev kaw lub valve.Hauv kuv lub teb chaws mus txog rau xyoo 1980s, npauj npaim li qub tau siv rau cov khoom siv qis qis, thiab lub rooj zaum valve yog ua los ntawm cov roj hmab hluavtaws.Los ntawm xyoo 1990, vim muaj kev sib pauv ntau ntxiv nrog cov teb chaws txawv teb chaws, tawv-foob (hlau-seal) npauj npaim li qub tau tsim sai heev.Tam sim no, muaj ntau lub tuam txhab valve uas tuaj yeem tsim nruab nrab-siab hlau-sau npauj npaim li qub, uas ua rau daim ntawv thov ntawm npauj npaim li qub dav dua.
Cov xov xwm uas tus npauj npaim valve tuaj yeem thauj thiab tswj tau suav nrog dej, dej condensed, dej ntws, dej phwj tuaj, dej hiav txwv, huab cua, roj, kua roj, hmoov qhuav, av nkos, txiv hmab txiv ntoo slurry thiab sib tov nrog cov khib nyiab pov tseg.
Npauj npaim li qub yog tsim rau kev khiav dej num.Txij li thaum lub siab poob ntawm npauj npaim valve nyob rau hauv lub raj xa dej kuj loj, nws yog li peb zaug ntawm lub valve.Yog li ntawd, thaum xaiv lub npauj npaim valve, qhov cuam tshuam ntawm kev poob siab ntawm cov kav dej yuav tsum tau txiav txim siab tag nrho.Lub siab poob ntawm lub phaj npauj npaim yuav tsum tau txiav txim siab thaum lub phaj npauj npaim kaw.Kev ruaj khov.Tsis tas li ntawd, nws yog ib qho tsim nyog yuav tau xav txog qhov kev txwv ntawm kev ua haujlwm kub uas cov khoom siv ntawm lub rooj zaum elastic tuaj yeem tiv taus qhov kub thiab txias.Cov txheej txheem ntev thiab tag nrho qhov siab ntawm npauj npaim valve yog me me, qhov qhib thiab kaw nrawm nrawm, thiab nws muaj cov yam ntxwv zoo tswj cov kua dej.Lub hauv paus ntsiab lus ntawm tus npauj npaim valve yog qhov tsim nyog tshaj plaws rau kev ua qhov loj-inch li qub.Thaum npauj npaim valve yuav tsum tau tswj kev khiav, qhov tseem ceeb tshaj plaws yog xaiv qhov loj thiab hom npauj npaim valve kom nws ua haujlwm tau zoo thiab zoo.
1. Feem ntau, nyob rau hauv throttling, tswj tswj thiab av nkos nruab nrab, cov qauv yuav tsum tau luv luv nyob rau hauv ntev thiab ceev ceev nyob rau hauv qhib thiab kaw ceev (1/4 kiv puag ncig).Tsis tshua muaj siab txiav-tawm (qhov sib txawv me me), npauj npaim valve raug pom zoo.
2. Cov npauj npaim valve tuaj yeem siv tau thaum hloov ob txoj haujlwm, nqaim channel, tsis tshua muaj suab nrov, cavitation thiab gasification tshwm sim, ib qho me me ntawm cov pa tawm mus rau hauv qhov chaw, thiab cov xov xwm abrasive muaj.
3. Thaum lub npauj npaim valve yog siv nyob rau hauv tshwj xeeb tej yam kev mob xws li throttling adjustment, los yog nruj sealing yuav tsum tau, los yog hnyav abrasion, tsis tshua muaj kub (cryogenic) thiab lwm yam kev khiav hauj lwm, nws yog tsim nyog los siv ib tug tshwj xeeb tsim hlau foob nrog ib tug triple eccentric los yog Muab ob npaug rau eccentric hloov cuab yeej Dedicated npauj npaim valve rau hauv av.
4. Lub centerline npauj npaim valve yog tsim rau cov dej tshiab, dej phwj tuaj, dej hiav txwv, dej ntsev, ncu, nkev roj, khoom noj, tshuaj, thiab roj uas yuav tsum tau ua kom tiav sealing, xoom gas test to, siab kev pab cuam lub neej, thiab ua hauj lwm kub ntawm - 10 ℃ ~ 150 ℃.Thiab ntau yam kua qaub thiab alkali thiab lwm cov kav dej.
5. Cov mos mos-sealed eccentric npauj npaim valve yog tsim rau ob txoj kev qhib thiab kaw thiab kev hloov kho ntawm qhov cua thiab plua plav tshem tawm cov kav dej, thiab siv dav hauv cov kav dej thiab cov dej hauv metallurgy, lub teeb kev lag luam, hluav taws xob fais fab, thiab petrochemical systems.
6. Cov hlau-rau-hlau hlau sealing ob chav eccentric npauj npaim valve yog tsim rau cov cua sov hauv nroog, cov khoom siv roj, cov khoom siv dej thiab lwm yam roj, roj, kua qaub thiab alkali pipelines, raws li cov khoom tswj thiab throttling.
7. Ntxiv rau kev siv los ua qhov loj-loj siab viav vias adsorption (PSA) cov khoom sib cais cov khoom siv tswj lub valve, Jinyong cov hlau nto kaw triple eccentric npauj npaim valve kuj tuaj yeem siv dav hauv roj av, petrochemical, tshuaj, metallurgical, hluav taws xob fais fab thiab lwm teb.Nws yog lub rooj vag valve thiab lub ntiaj teb valve.Ib qho khoom siv zoo.
