Lub diaphragm valve yog kaw-off valve uas siv lub diaphragm raws li nws qhov qhib thiab kaw lub ntsiab kom kaw txoj kev ntws, txiav tawm cov kua dej, thiab cais lub valve lub cev kab noj hniav los ntawm lub valve cover kab noj hniav. Nws yog hom tshwj xeeb ntawm kev kaw- tawm lub valve uas nws qhov qhib thiab kaw yog lub diaphragm ua los ntawm cov khoom muag, cais lub valve lub cev kab noj hniav los ntawm lub valve cover kab noj hniav thiab cov khoom tsav. Nws yog tam sim no dav siv nyob rau hauv ntau yam teb. Feem ntau siv diaphragm li qub muaj xws li roj hmab-lined diaphragm li qub, fluoropolymer-lined diaphragm li qub, unlined diaphragm li qub, thiab yas diaphragm li qub.
GNEE Group tau tsim cov diaphragm li qub rau 18 xyoo thiab muab cov lus qhia xaiv.Tiv tauj peb rau cov lus qhia xaiv.
Diaphragm Valve Ua Haujlwm Txoj Cai
Lub diaphragm valve hloov cov tsoos valve core sib dhos nrog corrosion-tiv thaiv hauv ob sab phlu thiab corrosion{1}}resistant diaphragm kom ua tiav cov dej tswj. Lub cev lub cev tuaj yeem ua los ntawm cov hlau cam khwb cia, cam khwb cia hlau, lossis cam khwb cia stainless hlau, ntxiv nrog ntau yam corrosion-resistant lossis hnav- cov ntaub ntawv tiv taus, xws li roj hmab thiab PTFE, raws li cov khoom siv diaphragm.
Qhov no diaphragm tsim muaj zoo heev corrosion kuj, muaj peev xwm tuav heev corrosive media xws li muaj zog acids thiab alkalis. Diaphragm li qub muaj cov qauv compact, tsis tshua muaj dej tsis kam, thiab muaj peev xwm txaus txaus piv rau lwm hom li qub ntawm tib yam tshwj xeeb.
Nws cov qauv tsim tshwj xeeb cais tawm qhov nruab nrab los ntawm lub tsev sab sauv ntawm lub qia valve, ua kom cov pa tawm - ua haujlwm dawb, ua rau nws zoo tagnrho rau kev tswj cov xov xwm nrog cov viscosity siab lossis cov khoom raug tshem tawm.
Nws yog ib nqi sau cia hais tias vim muaj kev txwv nyob rau hauv lub diaphragm thiab cov ntaub ntawv nyob rau hauv ob sab phlu, nws lub siab tsis kam thiab kub kuj kuj tsis muaj zog, feem ntau tsuas yog haum rau nominal pressures ntawm 1.6 MPa thiab kub hauv qab no 150 degree.
Diaphragm Valve Structure
Lub diaphragm valve yog ib hom valve uas tswj cov ntws los yog kev taw qhia ntawm cov kua los ntawm deforming lub diaphragm. Nws cov qauv tseem ceeb suav nrog:
- Valve Lub Cev: Txuas rau lub raj xa dej thiab tiv taus qhov siab ntawm qhov nruab nrab; feem ntau yog ua los ntawm cam khwb cia hlau, cam khwb cia hlau, stainless hlau, los yog engineering yas.
- Diaphragm: Lub caij qhib thiab kaw; Feem ntau yog ua los ntawm cov roj hmab, PTFE, los yog cov ntaub ntawv sib xyaw, muab kev tiv thaiv corrosion zoo heev thiab sealing kev ua tau zoo.
- Valve Disc: Txuas nrog lub diaphragm thiab deformed los ntawm kev sib hloov lossis nqa.
- Valve Npog: Bolted rau lub valve lub cev, tsim cov kab noj hniav uas muaj cov diaphragm thiab valve disc.
- Actuator: Ib phau ntawv, hluav taws xob, pneumatic, lossis hydraulic actuator uas tswj kev sib hloov lossis nqa ntawm lub valve disc.
- Sealing Surface: Qhov chaw sib cuag ntawm lub diaphragm thiab lub valve lub cev, kom ntseeg tau tias kev sib khi ruaj khov.
Performance Advantages thiab Limitations
Qhov zoo
Kev sib khi zoo: Qhov chaw sib cuag loj ntawm lub diaphragm thiab lub cev lub cev kom ntseeg tau tias kev sib khi zoo, haum rau kev siv siab sib txawv.
Kev tiv thaiv corrosion siab: Cov khoom siv diaphragm tuaj yeem xaiv raws li cov yam ntxwv ntawm qhov nruab nrab, ua rau nws haum rau corrosive media.
Tsis tshua muaj dej tsis kam: yooj yim ntws channel, tsis tshua muaj siab poob poob, thiab zoo zog txuag nyhuv.
Tsis muaj kev pheej hmoo ntawm kev xau: Lub diaphragm cais cov kua dej tawm ntawm lub tshuab tsav, ua rau nws tsim nyog rau cov tshuaj lom thiab muaj kev phom sij.
Kev siv ntau yam: Txhawb ntau yam kev tshaj tawm thiab kev ua haujlwm, thiab yooj yim los tswj.
Kev txwv
Tsawg lub neej diaphragm: Ntev- siv sij hawm ntev tuaj yeem ua rau diaphragm laus, hnav, lossis tawg.
Kev txwv qhov kub thiab txias: Siab -kub xov xwm tuaj yeem ua kom cov diaphragm aging, yuav tsum tau siv cov khoom tshwj xeeb.
Cov kev cai txwv kev ua haujlwm: feem ntau yog siv rau kev tswj / tawm, nrog kev tswj xyuas qhov tseeb.
Loj dua: Piv rau pob li qub, diaphragm li qub loj dua thiab siv ntau qhov chaw.
Tus nqi siab dua: Piv rau cov li qub qub, cov diaphragm li qub yog kim dua thiab muaj nqi kho dua.
Daim ntawv thov
Diaphragm li qub tau siv dav hauv kev lag luam hauv qab no:
- Tshuaj thiab Pharmaceuticals: Tswj corrosive, lom, thiab siab -purity media.
- Khoom noj khoom haus thiab dej haus: Ua raws li GMP cov qauv, siv rau kev tswj cov kav dej huv thiab cov tshuab xa tawm.
- Kev kho dej thiab kev tiv thaiv ib puag ncig: Tswj cov dej khib nyiab, tshuaj siv tshuaj, thiab rov qab osmosis systems.
