Cov ntaub ntawv twg feem ntau siv rau cov khoom siv kaw lub valve, thiab lawv cov ntsuas kev ua tau zoo tseem ceeb yog dab tsi?

Kev kaw lub valve yog ib qho thev naus laus zis thoob ntiaj teb uas tseem ceeb rau ntau yam kev lag luam. Tsis yog tsuas yog cov lag luam xws li roj av, tshuaj lom neeg, khoom noj, tshuaj, ua ntawv, hydropower, tsim nkoj, muab dej thiab dej ntws, smelting, thiab lub zog xwb uas nyob ntawm kev siv thev naus laus zis kaw, tab sis cov lag luam tshiab xws li aviation thiab aerospace kuj muaj feem cuam tshuam nrog nws.

Cov ntaub ntawv siv rau kev kaw lub valve feem ntau

Khoom siv roj hmab:Roj hmab yog ib qho ntawm cov ntaub ntawv siv feem ntau rau cov foob valve, tshwj xeeb tshaj yog nyob rau hauvnpauj npaimlub valvethiablub qhov rooj vagCov roj hmab feem ntau muaj xws li roj hmab Neoprene, vIon, thiab roj hmab silicon. Cov ntaub ntawv no muaj kev ywj pheej zoo heev thiab tiv taus corrosion, ua rau lawv haum rau kev kaw ntau yam xov xwm.

Telflon(PTFE):PTFE yog ib yam khoom siv yas ua tau zoo heev uas siv dav hauv cov foob pob valve. Nws cov tshuaj lom neeg thiab kub zoo heev ua rau nws tsim nyog siv rau hauv cov chaw uas muaj qhov kub thiab txias siab, siab siab, thiab cov xov xwm corrosive. PTFE foob feem ntau siv rau hauvxyuas cov li qubthiabnpauj npaim li qub.

Hlau:Cov hlau foob kuj siv dav hauv qee qhov kev siv tshwj xeeb. Cov foob no feem ntau yog ua los ntawm cov hlau tsis xeb, tooj liab, lossis lwm yam alloys thiab tsim nyog rau kev kaw cov li qub hauv qhov kub thiab txias, siab siab, thiab qhov chaw kub heev. Qhov zoo ntawm cov hlau foob yog lawv lub zog thiab kev ruaj khov mus sij hawm ntev.

Cov ntaub ntawv sib xyaw ua ke:Cov ntaub ntawv sib xyaw tau txais kev saib xyuas ntau ntxiv nyob rau xyoo tas los no. Cov ntaub ntawv no feem ntau muab cov txiaj ntsig ntawm roj hmab thiab yas sib xyaw ua ke, muab kev ua haujlwm zoo heev hauv ntau yam kev ua haujlwm. Kev siv cov ntaub ntawv sib xyaw tau txhim kho kev ua haujlwm ntawm cov li qub.

Cov ntsuas kev ua tau zoo ntawm cov khoom siv kaw lub valve

Thaum xaiv cov ntaub ntawv kaw lub valve, cov ntsuas kev ua tau zoo hauv qab no yuav tsum tau xav txog:

KubRkev tiv thaiv:Qhov kub ntawm cov khoom siv sealing yog ib qho cim qhia tseem ceeb rau kev ntsuam xyuas nws cov kev ua tau zoo. Cov ntaub ntawv sib txawv muaj ntau qib kev tiv taus kub. Cov ntaub ntawv roj hmab feem ntau haum rau qhov chaw kub qis, thaum PTFE thiab cov ntaub ntawv hlau haum rau cov ntawv thov kub siab.

Kev xebRkev tiv thaiv:Cov li qub feem ntau siv los thauj ntau yam tshuaj lom neeg, yog li qhov kev tiv thaiv xeb ntawm cov khoom siv sealing yog qhov tseem ceeb heev. PTFE thiab qee cov roj hmab tshwj xeeb zoo tshaj plaws hauv qhov no, zoo tiv taus xeb los ntawm ntau yam tshuaj lom neeg.

Kev Teeb Tsa Nruas:Qhov no ntsuas qhov muaj peev xwm ntawm cov khoom siv sealing los tswj nws cov khoom sealing hauv qab lub siab ntev. Qhov me dua qhov kev sib txuas, qhov zoo dua qhov kev ua tau zoo ntawm cov khoom siv sealing.

Kev ywj pheej& Rkev yooj yim:Qhov elasticity thiab resilience ntawm cov khoom siv sealing ncaj qha cuam tshuam rau nws cov nyhuv sealing. Qhov elasticity zoo ua kom lub nplhaib sealing tuaj yeem haum zoo thaum lub valve qhib thiab kaw, tiv thaiv kev xau.

Hnav tsis kam:Hauv qee qhov kev siv, cov ntaub ntawv kaw lub valve yuav tsum tiv taus kev hnav, yog li kev hnav tsis kam kuj yog qhov qhia txog kev ua tau zoo tseem ceeb. Cov hlau foob thiab qee cov ntaub ntawv sib xyaw ua tau zoo dua hauv qhov no.
