Sab Mounted Eccentric Ib Nrab Pob Valve
Nta
▪ Cov qauv tsim eccentric txo qhov qhib lub zog, txo qhov kev sib txhuam ntawm qhov chaw sib khi thiab ua rau lub neej ua haujlwm ntev.
▪ Cov dej tsis kam yog me me, thiab nws cov coefficient kuj yog sib npaug ntawm cov yeeb nkab seem nrog qhov ntev.
▪ Kev xaiv cov roj hmab lossis lub rooj zaum hlau kom paub tseeb tias lub valve tuaj yeem siv rau hauv kev ua haujlwm sib txawv.
▪ Nrog kev sib khi kom nruj thiab tsis muaj qhov xau rau kev sib kis ntawm cov pa phem.
▪ Kev ntsuas siab:
Plhaub Test Siab 1.5 x PN
Foob Test Siab 1.1 x PN
▪ Kev xaiv ntawm bimetallic sealing khub nrog sib txawv alloy (los yog ua ke pob) rau surfacing yuav siv tau rau kev ua hauj lwm tej yam kev mob nrog hnav tsis kam, corrosion kuj, kub tsis kam thiab nruj sealing yuav tsum tau:
1. Feem ntau siv valve: Loj DN40 ~ 1600, haum rau kev kho cov dej phwj tuaj, cov ntaub so ntswg, cov cua sov hauv nroog thiab lwm lub sijhawm nrog cov kev cai nruj.
2. Tshwj xeeb valve rau petrochemical kev lag luam: Loj DN140 ~ 1600. Nws yog tsim rau cov roj crude, cov roj hnyav thiab lwm yam khoom siv roj, tsis muaj zog corrosion thiab ob-theem mix flow media hauv kev lag luam tshuaj.
3. Tshwj xeeb valve rau cov pa roj: Loj DN40 ~ 1600, muaj feem xyuam rau kev tswj kev sib kis ntawm cov roj, cov roj ntsha thiab cov roj liquefied.
4. Tshwj xeeb valve rau slurry: Loj DN40 ~ 1600, muaj feem xyuam rau industrial pipeline tsheb thauj mus los nrog crystallization nag lossis daus nyob rau hauv cov kua thiab cov khoom ob-theem sib xyaw ntws los yog tshuaj lom neeg cov tshuaj tiv thaiv hauv kev thauj mus los ua kua.
5. Tshwj xeeb valve rau pulverized thee tshauv: Loj DN140 ~ 1600. Nws muaj feem xyuam rau kev tswj fais fab nroj tsuag, hydraulic slag tshem tawm los yog gaseous kis pipeline.

Schematic
Daim ntawv thov
▪ Lub eccentric hemispherical valve siv lub eccentric valve lub cev, eccentric pob thiab lub rooj zaum valve.Thaum lub valve qws tig, nws yog cia li nruab nrab ntawm txoj kev sib.Qhov ntau nws raug kaw, qhov nruj dua yog nyob rau hauv cov txheej txheem kaw, thiaj li ua tiav lub hom phiaj ntawm kev sib khi zoo.
▪ Lub pob ntawm lub valve raug cais tawm tag nrho ntawm lub rooj zaum valve, uas tshem tawm qhov hnav ntawm lub nplhaib sealing thiab kov yeej qhov teeb meem uas lub rooj zaum pob valve thiab lub pob sealing nto ib txwm hnav.Cov khoom siv tsis yog xim hlau yog embedded rau hauv lub rooj zaum hlau, thiab cov hlau saum npoo ntawm lub rooj zaum valve yog kev tiv thaiv zoo.
▪ Lub valve no tshwj xeeb tshaj yog tsim rau kev lag luam steel, aluminium kev lag luam, fiber ntau, micro khoom hais, pulp, thee tshauv, roj av thiab lwm yam xov xwm.
