Dab tsi yog plug valve thiab dab tsi yog plug li qub siv rauthiab pob li qub hauv series.
Plug li qub tau siv dav hauv cov txheej txheem kev lag luam, cov li qub no ua haujlwm los ntawm kev sib hloov thiab siv los nres thiab pib cov kua dej. Plug li qub yog qhov pib ntawm - tawm li qub, raws li lub ntsaws nrog lub qhov sib npaug uas cov kua dej ntws tawm. Lub ntsaws yuav tapered los yog cylindrical thiab lawv nyob rau hauv lub valve lub cev, ib lub quarter- tig tig yog ua kom cov yeeb nkab thiab qhov nyob rau hauv tib txoj kab thiab qhov no yuav yog lub xeev qhib thiab kaw lub xeev, nws yuav hla lub yeeb nkab. Plug li qub yog qhov yooj yim los hloov thiab lawv tsim nyog rau kev siv ntau qhov chaw, yog li ntawd lub valve tuaj yeem siv los hloov qhov ntws. Nyob rau hauv parallel plugs, cov duab ntawm qhov chaw nres nkoj yog rectangular thiab triangular rau taper plugs. Vim qhov zoo li no, lub valve slimmer tuaj yeem tsim nrog qhov hnyav dua. Feem ntau cov ntsaws li qub yog siv rau kev pib thiab nres qhov ntws, nws kuj tseem siv tau rau kev khiav dej. Plug li qub muaj peev xwm tswj tau cov kua dej nrog cov khib nyiab hauv kev ncua vim tias lub rooj zaum txav mus rau ib leeg nrog cov lus tsa suab thiab hauv qhov qhib siab.
Los ntawm kev siv lub lubricated ntsaws lub valve tuaj yeem tsim kho, uas siv cov roj nplua nyeem ua haujlwm kom zoo tshaj qhov ntau ntawm cov kev kub ntxhov.
Muaj cov qauv tsim tsis muaj roj, uas suav nrog cov ntsaws ruaj ruaj hauv lub ntsaws thiab yuav tsum muaj cov kabmob yas.
Dab tsi yog cov khoom ntawm lub ntsaws valve
Yuav ua li cas ntsaws li qub
Tapered plug thiab lub cev yog qhov tseem ceeb ntawm lub ntsaws valve, qhov siab tshaj plaws khiav efficiency tuaj yeem tsim los ntawm kev tsim kom zoo ntawm sab hauv contours ntawm lub valve. Feem ntau nyob rau hauv tapered plug, qhov chaw nres nkoj yog duab plaub -zoo li tus thiab muaj round ports. Tag nrho cov dej tau txais thaum lub qhov qhib hauv lub ntsaws ntsaws ntsaws ntsaws ruaj ruaj nyob rau hauv cov kev taw qhia ntawm ntws thiab thaum lub ntsaws yog tig ib lub quarter tig ntws yog txiav.
Lub ntsaws valve ua haujlwm li cas
Nrog kev pab los ntawm lub cylindrical los yog tapered plug, lub plug valve ua lub quarter-tig kev khiav hauj lwm los ntawm tag nrho qhib mus rau tag nrho lub xeev. Lub plug muab ib lub qhov los ntawm ib tug axis, uas muaj peev xwm txuas lub inlet thiab qhov hluav taws xob valve, yog li nyob rau hauv ib tug qhib txoj hauj lwm, yuav muaj ib tug ncaj- los ntawm kev khiav, qhov ntws yuav raug thaiv kom zoo thaum nws tig 90. degrees mus rau qhov chaw kaw.
Dab tsi yog hom ntsaws valve
Lubricated plug valve
In a lubricated plug valve, the plug is provided with a cavity in the middle along its axis. This cavity is closed at the bottom and fitted with sealant injection fitting at the top. The cavity is injected with sealant and the sealant is prevented from flowing in the reverse direction by the check valve below the injection fitting. Lubricated plug valves are safe from fire and have a better life. These valves are used in power plants because of their small size. These valves are able to handle gas and fuel. There won't be any danger due to leak because they are properly sealed.
Tsis yog -lubricated plug valve
Nyob rau hauv lub cev kab noj hniav ntawm cov uas tsis yog -lubricated plug li qub, lub tes tsho los yog ib tug elastomeric lub cev liner raug ntsia. Lub tapered thiab polished plug yuav ua raws li ib tug wedge thiab nias lub tes tsho tiv thaiv lub cev. Yog li kev sib txhuam ntawm lub cev thiab lub ntsaws yog txo los ntawm kev pab los ntawm ib lub tes tsho uas tsis yog -hlau
Dab tsi yog eccentric plug valve
Cov li qub no tau muab nrog cov plugs uas tau muab tshem tawm ntawm -center. Cov ntsaws li qub no siv rau hauv cov kev pabcuam corrosive thiab abrasive rau ntawm -tawm kev ua haujlwm. Cov ntsaws li qub no txav mus rau hauv thiab tawm ntawm lub rooj tshem tawm kev hnav tsis zoo.
Dab tsi yog qhov txawv ntawm qhov ntsaws valve thiab pob valve
Qhov sib txawv loj yog lawv ua haujlwm li cas, hauv lub pob valve nws siv lub pob zoo li lub rooj vag yog siv los kaw qhov ntws, thaum nyob rau hauv cov ntaub ntawv ntsaws valve nws siv lub ntsaws los kaw qhov ntws.
Dab tsi yog qhov zoo ntawm plug li qub
Flow kev cai
Qhov loj ntawm lub valve no me me kom nws tsuas yog siv qhov chaw tsawg dua
Nws muab kaw nruj, qhib ceev thiab qis -siab poob
Kev nyab xeeb hluav taws
Plug thiab lub cev zaum qhov chaw tsis raug rau cov kab kua dej, uas yuav txo tau cov corrosion thiab yaig loses
Nws tuaj yeem siv nrog cov nqi ntws loj
Dab tsi yog qhov tsis zoo ntawm plug li qub
Plug li qub tuaj yeem raug ua rau galling
Vim muaj kev sib txhuam siab, yuav tsum muaj zog ntau dua los ua kom muaj zog
Tsis haum rau kev siv throttling
Txo qhov chaw nres nkoj vim tapered plug
Lub ntsaws yuav puas vim yog kev sib txhuam ntawm lub ntsaws thiab lub cev
Dab tsi yog cov kev siv ntawm plug valves
Kev kho tej thaj chaw deb yog ua tau
Nres thiab pib ntws
Gases kua thiab tsis yog -abrasive slurries
Nws tuaj yeem siv rau kev siv roj piping system
Cov li qub no tau siv dav hauv cov tshuab ua kom zoo
Nws yog siv nyob rau hauv chemical industries
Fly tshauv siv
Nqus mus rau siab - cov ntawv thov siab
Nws tuaj yeem siv rau kev thaiv
