Sealing kev ua tau zoo ntawm vuam flange gasket

Sealing kev ua tau zoo ntawm vuam flange gasket

Gasket yog ib qho tseem ceeb ntawm kev sib khi. Cov khoom siv gasket tsim nyog yuav tsum xav txog tias lub gasket tuaj yeem tsim qhov tsim nyog elastic deformation yam tsis tau crushed los yog squeezed nyob rau hauv qhov kev txiav txim ntawm tsim nyog preload. Thaum ua hauj lwm, lub flange sealing nto qhov sib txawv yog nce, thiab cov khoom siv gasket yuav tsum muaj qhov muaj zog txaus los ua kom lub gasket nto thiab cov flange nto ze ze kom muaj kev sib khi zoo.

Kev quab yuam ua ntej nruj tuaj yeem ua kom ntseeg tau tias lub gasket tuaj yeem tswj tau qee qhov kev foob tshwj xeeb thaum ua haujlwm. Yog hais tias lub pre-tightening quab yuam loj heev, lub gasket yuav crushed los yog squeezed, yog li ntawd tawg lub foob. Kev faib tawm ntawm preload ntawm lub gasket tseem cuam tshuam rau kev ua haujlwm sealing. Cov txheej txheem los xyuas kom meej qhov sib txawv ntawm lub zog ua ntej nruj yog txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau nruj.

1. Lub taub qab vuam flange yog ib hom yeeb nkab haum. Hais txog lub flange nrog lub caj dab thiab cov yeeb nkab hloov seem, nrog rau lub taub qab vuam txuas nrog cov yeeb nkab. Lub taub qab vuam flange tsis yooj yim rau deform, muaj kev sib khi zoo thiab siv dav. Nrog rau qhov sib xws rigidity thiab elasticity xav tau, pob tw vuam thinning hloov pauv yog tsim nyog. Qhov kev ncua deb ntawm qhov vuam seam thiab qhov sib koom ua ke yog qhov loj, thiab qhov sib koom ua ke tsis muaj vuam kub deformation.

Qhov kev ncua deb ntawm qhov vuam seam thiab qhov sib koom ua ke yog qhov loj, thiab qhov sib koom ua ke tsis muaj vuam kub deformation. Ib qho nyuaj hnoos horn qauv yog saws. Nws yog qhov tsim nyog rau cov kav dej uas muaj kev kub ntxhov loj thiab qhov kub thiab txias hloov los yog kub, kub kub thiab kub tsis tshua muaj cov kav dej. Feem ntau siv rau cov kav dej nrog PN siab dua 2.5 MPa. Kev sib txuas ntawm cov kav dej thiab cov li qub; kuj tseem siv los thauj cov khoom kim heev, flammable thiab explosive media pipelines.
