Mos Foob Bi-direction Npauj Npaim Valve
Khoom Paub meej
Npauj npaim valve yog ib qho ntawm obstructing li qub los txuas lossis thaiv qhov nruab nrab hauv cov kav dej, nws kuj tuaj yeem kho qhov ntws ntawm nruab nrab hauv cov kav dej.Nws cov khoom kaw (disc) yog nyob rau hauv cov duab ntawm disc uas tuaj yeem tig lub axis nws tus kheej los thaiv qhov nruab nrab hauv cov raj xa dej lossis kho qhov ntws.
Mos foob bi-direction npauj npaim valve yog ob chav eccentric npauj npaim valve, tseem hu ua npauj npaim valve ua haujlwm siab.Cov nyhuv ntawm ob chav eccentricity ua rau lub phaj tuaj yeem tawm sai sai ntawm lub rooj zaum valve tom qab qhib, zoo heev tshem tawm qhov tsis tsim nyog extrusion thiab scraping tshwm sim ntawm lub phaj thiab lub rooj zaum valve, nws txo qhov qhib qhov deb, txo qhov hnav, thiab txhim kho lub neej. lub rooj zaum valve.
Qauv
Npauj npaim valve feem ntau muaj lub cev, disc, qia, lub rooj zaum, lub nplhaib sib khi, lub caj pas ntim thiab cov ciaj ntswj (lossis actuator nrog handwheel) thiab lwm yam, thov saib cov duab hauv qab no ntawm npauj npaim valve siv.Npauj npaim valve muaj 2 hom kev sib txuas: flanged thiab wafer, lub cev ntawm wafer hom valve feem ntau yog nrog lugs thiaj li yuav concentric nrog machining flange ntawm cov kav dej.
Cov yam ntxwv ua haujlwm
1.Has isobaric bi-directional sealing kev ua tau zoo, txhim khu kev qha sealing kev ua tau zoo;
2.Small face-to-face dimension Ntawm txhua yam ntawm li qub, npauj npaim valve muaj qhov tsawg tshaj plaws ntsej muag-rau-Face dimension, tshwj xeeb tshaj yog cov wafer hom npauj npaim valve lub ntsej muag-rau-lub ntsej muag dimension yog deb me dua nominal qhov ntev.
3.Siv cov qauv semi-axial nrog loj hla qhov chaw ntws thiab me me ntws tsis kam;
4.Siv ob chav eccentric qauv, lub valve lub cev sealing nto yog kiag li detached los ntawm lub valve phaj sealing nto tom qab qhib, tsis muaj kev sib txhuam, lub neej ntev;
5.Raws li qhov xav tau ntawm tus neeg siv khoom, lub rooj zaum roj hmab cov ntsaws ruaj ruaj tuaj yeem xaiv tau rau ntawm lub cev lossis disc;
6. Qhib thiab kaw yog ceev thiab yooj yim nrog lub zog me me
Lub disc tig 90 o uas tuaj yeem qhib thiab kaw lub valve vim tias qhov nruab nrab quab yuam tawm tsam txhua sab ntawm lub disc yuav luag sib npaug thiab qhov tshwm sim ntawm lub zog yog thim rov qab, yog li qhov kev tawm ntawm lub zog yog txiav txim siab los ntawm kev sib tsoo ntawm qhov sib khi.
7.Kev tswj xyuas kev ua haujlwm zoo
Los ntawm kev hloov pauv tus tubtxib saum ntuj ntawm lub disc, lub valve tuaj yeem faib cov kev tswj xyuas qhov nruab nrab ntawm cov kav dej, qhib qhov taw qhia thiab txwv cov cuab yeej nyob rau sab saum toj ntawm npauj npaim valve.
8.Simple qauv, me me, lub teeb yuag, haum rau loj loj valve.
9. Kab rov tav mounting phau ntawv valve muaj bi-directional zaub muaj nuj nqi, qhib lub xeev ntawm lub valve tuaj yeem pom synchronously los ntawm kev khiav hauj lwm nto thiab sab.
Siv tau nruab nrab
Siv dav hauv kev siv dej thiab dej, metallurgy, roj av, tshuaj lom neeg kev lag luam, hluav taws xob hluav taws xob, kev tsim kho hauv nroog thiab lwm yam kev lag luam pipelines los txiav tawm, txuas thiab tswj kev siv nruab nrab.
