Hollow dav hlau valve DN1500
Hollow Dav Hlau Valve
Lub hollow dav hlau valve yog ib hom valve siv nyob rau hauv cov dej tswj systems. Lub valve no yog tsim los nrog lub hollow los yog kab noj hniav nyob rau hauv nws qhov chaw, tso cai rau cov kua los ntawm nws.
Lub hollow dav hlau valve yog ib hom valve siv nyob rau hauv cov dej tswj systems. Lub valve no yog tsim los nrog lub hollow los yog kab noj hniav nyob rau hauv nws qhov chaw, tso cai rau cov kua los ntawm nws. Nws yog feem ntau siv rau hauv cov ntawv thov uas muaj kev tshaj tawm siab thiab kev tswj xyuas cov kua dej yog qhov tseem ceeb. Lub hollow dav hlau valve feem ntau muaj lub cev nrog lub qhov hluav taws xob thiab qhov hluav taws xob, thiab lub tshuab txav tau los yog disc uas tswj cov dej ntws. Thaum lub valve nyob rau hauv qhov chaw kaw, lub qhov ncauj thaiv cov dej ntws. Raws li lub valve qhib los ntawm kev txav lub qhov ncauj tawm ntawm lub rooj zaum, cov kua dej tuaj yeem dhau los ntawm qhov chaw hollow thiab tawm los ntawm qhov hluav taws xob.
Hollow dav hlau li qub feem ntau yog siv rau hauv lub pas dej da dej, thiab tsim hluav taws xob. Lawv muaj txiaj ntsig tshwj xeeb hauv kev tswj cov dej siab los yog siab tshaj tawm, qhov twg muaj kev tswj xyuas meej thiab ua haujlwm tau zoo. Cov qauv tsim thiab cov ntaub ntawv siv nyob rau hauv hollow dav hlau li qub tuaj yeem sib txawv nyob ntawm cov ntawv thov tshwj xeeb thiab hom kua dej tswj. Cov yam ntxwv xws li siab, qhov kub thiab txias, thiab tshuaj lom neeg yuav tsum tau xav txog thaum xaiv lub dav hlau hollow valve rau ib qho system. Kev saib xyuas tsis tu ncua thiab kev tshuaj xyuas yog ib qho tseem ceeb los xyuas kom meej cov kev ua haujlwm zoo ntawm cov li qub thiab tiv thaiv kom tsis txhob muaj dej los yog tsis ua haujlwm.
Peb cov hollow-jet li qub tau ua pov thawj lawv cov kev ua haujlwm siab hauv cov chaw tsim hluav taws xob hluav taws xob thiab cov kav dej. Lawv xyuas kom muaj kev tswj hwm thiab ib puag ncig zoo tshaj qhov hluav taws xob ntawm cov dej mus rau sab nraud lossis hauv cov dej hauv qab. Cov dej kuj tseem muaj cov pa oxygen nyob rau tib lub sijhawm. Cov khoom siv hlau zoo ntawm cov hollow-jet li qub ua ke nrog elastic / metallic sealing enables lub zog dissipation yam tsis muaj cavitation.
- Tsim nta-
◆ Hauv kev siv lub pas dej da dej, tswj cov li qub xws li Hollow jet li qub tau teeb tsa tom qab npauj npaim li qub ntawm lub qhov hluav taws xob sab. Cov li qub no ib txwm ua haujlwm raws li kev tswj hwm lossis tswj cov li qub. Hallow dav hlau li qub tsim los ua kev tswj lossis tswj.
◆ ua haujlwm hauv cov dej xa dej yam tsis muaj kev vibration ntau npaum li lub valve qhib.
-Qhov zoo-
◆ Kev kho kom raug
◆ Tsis muaj cavitation
◆ Tsis muaj kev vibration
◆ Kev khiav hauj lwm phau ntawv xav tau kev quab yuam tsawg. Txawm hais tias qhov xwm txheej piston, lub zog yuav tsum tau txav mus rau piston huab cua ntawm qhov qhib thiab kaw zoo tib yam.
◆ Vim tias tso pa tawm rau huab cua tsis muaj qhov ua rau muaj kev kub ntxhov thiab tsis tas yuav tsum tau teeb tsa cov dej rauj hauv qab.
◆ Kev saib xyuas yooj yim
