Hlau zaum ntsaws valve yog dab tsi?
Hlau zaum ntsaws valve muaj ib kab noj hniav nyob rau hauv nruab nrab ntawm plug raws nws axis.Cov kab noj hniav no yog kaw rau hauv qab thiab haum nrog sealant-txhaj tshuaj haum rau saum.Lub sealant yog txhaj rau hauv cov kab noj hniav, thiab ib daim tshev valve hauv qab qhov kev txhaj tshuaj haum tiv thaiv lub sealant los ntawm kev ntws rov qab.Lub sealant oozes tawm ntawm qhov chaw kab noj hniav los ntawm qhov radial qhov rau hauv cov roj nplua nyeem uas txuas mus rau qhov ntev ntawm qhov chaw zaum ntawm lub ntsaws.
Yuav kom txo tau lub torque ntawm cov pa hlau rooj lubricated plug li qub,Hlau zaum ntsaws valveyog invented thiab dav siv.Ntxiv nrog rau cov yam ntxwv ntawm cov pa roj ubricated ntsaws li qub, lub siab sib npaug ntsaws li qub kuj muaj cov yam ntxwv hauv qab no:
- 1. Thaum lub valve qhib, lub siab nyob rau hauv lub qis chamber ntawm lub valve lub cev yog sib npaug nrog lub nruab nrab siab nyob rau hauv lub pipeline.Cov roj sealing siab nyob rau hauv lub chamber sab sauv ua rau lub cev ntsaws ntsaws rau hauv qab, thiab qhov sib txawv me ntsis tshwm ntawm lub ntsaws ntsaws thiab lub sealing nto ntawm lub valve lub cev, lub torque ntawm lub rotating plug lub cev yog zoo txo.
- 2. Nyob rau hauv qhov kub thiab txias, lub thermal expansion ntawm lub ntsaws tuaj yeem nqus tau los ntawm nws qhov nce thiab poob.Roj lubricated plug valve, txawm hais tias kev siv roj lubrication tuaj yeem txo qhov qhib thiab kaw torque, tab sis nws tuaj yeem tsim muaj kuab paug ntawm qhov nruab nrab.Yog li ntawd, cov roj nplaum kaw tau raug xaiv rau qhov kev ua haujlwm tiag tiag.
Cov yam ntxwv tseem ceeb ntawm Hlau zaum ntsaws valve
Nta thiab cov txiaj ntsig ntawmHlau zaum ntsaws valve
- 1.Cov khoom muaj cov qauv tsim nyog, txhim khu kev qha sealing, kev ua tau zoo heev thiab zoo nkauj tsos.
- 2.Nws muaj cov qauv ntawm flip-clip balanceable siab thiab lub teeb rau / tawm ua haujlwm.
- 3.Cov ntaub ntawv ntawm qhov chaw thiab qhov ntau thiab tsawg ntawm flanges tuaj yeem tsim tsim nyog raws li kev ua haujlwm tiag tiag ntawm cov neeg siv khoom, kom ua tau raws li ntau yam kev xav tau ntawm engineering.
