Yuav ua li cas xaiv cov khoom siv sealing kom raug

Muaj tej yam tseem ceeb twg uas yuav tsum xav txog thaum xaiv cov khoom siv foob kom raug rau daim ntawv thov?

Tus nqi zoo thiab cov xim tsim nyog

Muaj cov foob

Txhua yam uas cuam tshuam rau hauv lub kaw lus sealing: piv txwv li qhov kub thiab txias, kua dej thiab siab

Cov no yog cov yam tseem ceeb uas yuav tsum xav txog hauv koj lub kaw lus sealing. Yog tias paub txhua yam, nws yuav yooj yim rau kev xaiv cov khoom siv zoo.

Tiam sis qhov yuav tsum tau ua ua ntej yog cov khoom siv yuav tsum ruaj khov. Yog li thawj qhov uas yuav tsum xav txog yog kev ua tau zoo ntawm kev siv tshuab. Cia peb pib nrog qhov ua tau zoo.

Lub neej ua haujlwm ntawm lub kaw lus thiab tus nqi yog cov yam tseem ceeb (Tiv tauj peb - ​​​​Tianjin Tanggu Water-Seal Valve Co., Ltd) yuav tsum xav txog. Txhua yam yuav cuam tshuam rau koj daim ntawv thov kev ua tau zoo. Nws yog ib qho tseem ceeb uas yuav tsum xav txog cov yam ntxwv tsim raws li daim ntawv thov. Qhov no suav nrog cov ntaub ntawv siv, cov duab kho vajtse thiab cov txheej txheem tsim khoom. Kuj tseem muaj cov yam ntxwv ib puag ncig uas yuav tsum xav txog suav nrog: siab, kub, lub sijhawm, sib dhos thiab xov xwm.

elastomer

Cov elastomers nrov vim lawv qhov elasticity zoo. Tsis muaj lwm yam khoom siv uas muaj tib theem ntawm elasticity.

Lwm cov ntaub ntawv xws li polyurethanes thiab thermoplastics tiv taus kev siab ntau dua li elastomers.

Cov ntaub ntawv roj hmab siv tau rau ntau yam kev siv sib txawv.

Cov khoom siv kho tshuab tseem ceeb suav nrog

kev ywj pheej

qhov nyuaj

lub zog tensile

Lwm yam tseem ceeb xws li

•Kev teeb tsa compression

•tiv taus cua sov

•kev hloov pauv kub tsawg

•kev sib raug zoo ntawm tshuaj lom neeg

•Tiv thaiv kev laus

•kev tiv thaiv kev sib txhuam

Qhov tseem ceeb tshaj plaws yog qhov elasticity ntawm cov roj hmab. Cia peb kawm ntxiv txog qhov no.

Kev ywj pheej yog qhov tshwm sim ntawm kev sib xyaw ua ke. Cov ntaub ntawv elastomeric, xws li roj hmab sib xyaw ua ke, yuav rov qab mus rau lawv cov duab qub yog tias deformed.

Cov ntaub ntawv tsis ywj pheej, xws li roj hmab tsis tau vulcanized, yuav tsis rov qab mus rau lawv lub xeev qub yog tias deformed. Vulcanization (xws liob chav flange npauj npaim valve) yog cov txheej txheem ntawm kev hloov roj hmab mus rau hauv cov khoom siv elastomeric.

Kev xaiv cov elastomers feem ntau yog raws li:

•ntau yam ntawm qhov kub ua haujlwm

•Kev tsis kam rau cov kua thiab cov pa roj

•Kev tiv thaiv huab cua, ozone thiab UV rays

Kev xaiv cov elastomers feem ntau yog raws li:

•ntau yam ntawm qhov kub ua haujlwm

•Kev tsis kam rau cov kua thiab cov pa roj

•Kev tiv thaiv huab cua, ozone thiab UV rays

Rau yam uas yuav tsum tau xav txog thaum xaiv cov ntaub ntawv saum npoo ntawm lub valve sealing

Qhov chaw sealing yog qhov chaw ua haujlwm tseem ceeb tshaj plaws ntawmlub valve, qhov zoo ntawm qhov chaw sealing ncaj qha cuam tshuam rau lub neej ua haujlwm ntawmlub valve, thiab cov khoom siv ntawm qhov chaw sib khi yog ib qho tseem ceeb kom ntseeg tau tias qhov zoo ntawm qhov chaw sib khi. Yog li ntawd, cov hauv qab no yuav tsum tau xav txog thaum xaiv cov khoom siv ntawm qhov chaw sib khi valve:

①Kev tiv thaiv xeb. "Kev xeb" yog tus txheej txheem uas qhov chaw ntawm qhov chaw kaw raug puas tsuaj raws li qhov kev ua ntawm cov khoom siv. Yog tias qhov chaw ntawm qhov chaw kaw raug xeb, kev ua haujlwm kaw tsis tuaj yeem lav tau, yog li cov khoom siv ntawm qhov chaw kaw yuav tsum tiv thaiv xeb. Kev tiv thaiv xeb ntawm cov khoom siv feem ntau nyob ntawm cov khoom sib xyaw thiab nws cov tshuaj lom neeg ruaj khov.

②Tiv Thaiv Kev Sib Tsoo. "Kos" txhais tau tias kev puas tsuaj los ntawm kev sib txhuam ntawm cov khoom siv thaum lub sijhawm txav mus los ntawm qhov chaw kaw. Hom kev puas tsuaj no yuav ua rau qhov chaw kaw puas tsuaj. Yog li ntawd, cov khoom siv ntawm qhov chaw kaw yuav tsum muaj cov khoom tiv thaiv kev khawb zoo, tshwj xeeb tshaj yog rau cov qhov rooj vag. Qhov kev tiv thaiv khawb ntawm cov khoom siv feem ntau yog txiav txim siab los ntawm cov khoom sab hauv ntawm cov khoom siv.

③Kev tiv thaiv kev yaig. "Kev yaig" yog cov txheej txheem ntawm kev rhuav tshem qhov chaw sib khi thaum cov khoom nruab nrab ntws los ntawm qhov chaw sib khi ntawm qhov ceev ceev. Hom kev puas tsuaj no pom tseeb dua ntawm cov qhov cua thiab cov qhov cua kev nyab xeeb siv rau hauv cov khoom nruab nrab kub thiab siab, thiab muaj kev cuam tshuam loj heev rau kev puas tsuaj ntawm kev ua haujlwm sib khi. Yog li ntawd, kev tiv thaiv kev yaig kuj yog ib qho ntawm cov kev xav tau tseem ceeb rau cov khoom siv sib khi.

④Nws yuav tsum muaj qee qhov nyuaj, thiab qhov nyuaj yuav poob qis heev nyob rau hauv qhov kub ua haujlwm teev tseg.

⑤Tus coefficient ntawm kev nthuav dav ntawm qhov chaw sealing thiab cov khoom siv lub cev yuav tsum zoo sib xws, uas yog qhov tseem ceeb dua rau cov qauv ntawm lub nplhaib sealing, yog li kom tsis txhob muaj kev ntxhov siab ntxiv thiab loosening ntawm qhov kub siab.

⑥Siv nyob rau hauv qhov kub thiab txias, yuav tsum muaj txaus anti-oxidation, thermal qaug zog tsis kam thiab thermal voj voog teeb meem.

Nyob rau hauv qhov xwm txheej tam sim no, nws nyuaj rau nrhiav cov khoom siv sealing nto uas ua tau raws li cov kev cai saum toj no. Peb tsuas tuaj yeem tsom mus rau kev ua kom tau raws li cov kev cai ntawm qee yam raws li ntau hom valve thiab kev siv. Piv txwv li, cov valve siv rau hauv cov xov xwm ceev ceev yuav tsum tau them sai sai rau qhov yuav tsum tau tiv thaiv kev yaig ntawm qhov chaw sealing; thiab thaum cov xov xwm muaj cov khoom tsis huv, cov khoom siv sealing nto uas muaj qhov nyuaj dua yuav tsum tau xaiv.
