Cov qauv ntawm covdiaphragm valvenws txawv heev ntawm qhov qub li qub.Nws yog hom tshiab ntawm lub valve thiab ib daim ntawv tshwj xeeb ntawm kev kaw lub valve.Nws qhov qhib thiab kaw yog ib lub diaphragm ua los ntawm cov mos mos Lub puab kab noj hniav ntawm lub hau thiab cov tsav tsheb yog sib cais, thiab tam sim no tau dav siv nyob rau hauv ntau yam teb.Feem ntau siv diaphragm li qub muaj xws li roj hmab-lined diaphragm li qub, fluorine-lined diaphragm li qub, unlined diaphragm li qub, thiab yas diaphragm li qub.
Diaphragm valve yog nruab nrog ib lub diaphragm hloov tau los yog ua ke diaphragm nyob rau hauv lub valve lub cev thiab lub valve cover, thiab nws kaw qhov yog ib tug compression ntaus ntawv txuas nrog lub diaphragm.Lub rooj zaum valve tuaj yeem yog hom weir lossis hom ncaj nraim.
Qhov kom zoo dua ntawm lub diaphragm valve yog tias nws cov txheej txheem kev khiav hauj lwm yog sib cais los ntawm qhov nruab nrab, uas tsis tsuas yog ua kom lub purity ntawm lub nruab nrab ua hauj lwm, tab sis kuj tiv thaiv tau qhov nruab nrab nyob rau hauv lub raj xa mus rau qhov chaw ntawm lub operating mechanism.Tsis tas li ntawd, tsis muaj kev sib cais ntawm txhua yam yuav tsum tau muaj nyob rau ntawm qia, tshwj tsis yog muaj kev nyab xeeb hauv kev tswj hwm kev tshaj tawm phom sij.
Nyob rau hauv lub diaphragm valve, txij li thaum lub nruab nrab ua hauj lwm tsuas yog nyob rau hauv kev sib cuag nrog lub diaphragm thiab lub valve lub cev, ob qho tib si uas yuav siv tau ntau yam ntawm cov ntaub ntawv sib txawv, yog li ntawd lub valve muaj peev xwm tswj tau ib tug ntau yam ntawm kev ua hauj lwm xov xwm, tshwj xeeb tshaj yog haum rau tshuaj corrosive los yog suspended hais.nruab nrab.
Kev khiav hauj lwm kub ntawm lub diaphragm valve feem ntau yog txwv los ntawm cov ntaub ntawv siv rau lub diaphragm thiab valve lub cev hauv ob sab phlu, thiab nws cov kev khiav hauj lwm kub yog li ntawm -50 mus rau 175 ° C.Lub diaphragm valve muaj cov qauv yooj yim thiab tsuas yog tsim los ntawm peb qhov tseem ceeb: lub cev lub cev, lub diaphragm thiab lub valve npog sib dhos.Lub valve yog ib qho yooj yim rau disassemble thiab kho sai, thiab kev hloov ntawm lub diaphragm tuaj yeem ua tiav ntawm qhov chaw thiab hauv lub sijhawm luv luv.
Diaphragm valve khoom:
Cov khoom siv hauv ob sab phlu (code), kev ua haujlwm kub (℃), haum nruab nrab

Mos Roj Hmab (BR) -10 ~ 85 ℃ Cement, av nplaum, cinder tshauv, granular chiv, cov kua dej uas muaj zog abrasiveness, ntau yam ntawm cov hnoos qeev tuab, thiab lwm yam.
fluorine roj hmab (CR) -10 ~ 85 ℃ Tsiaj thiab zaub roj, roj nplua nyeem thiab corrosive av nkos nrog ntau yam pH qhov tseem ceeb.
Butyl roj hmab (HR) -10 ~ 120 ℃ Organic acids, alkalis thiab hydroxide compounds, inorganic ntsev thiab inorganic acids, elemental gas alcohols, aldehydes, ethers, ketones, thiab lwm yam.
Polyvinylidene fluoride propylene yas (FEP) ≤150 ℃ Hydrochloric acid, sulfuric acid, aqua regia, organic acid, muaj zog oxidant, alternating concentrated acid, alternating acid thiab alkali thiab ntau yam organic acids tsuas yog molten alkali hlau, elemental fluorine thiab aromatic hydrocarbons hnyav, thiab lwm yam. .
Polyvinylidene fluoride yas (PVDF) ≤100 ℃

Enamel ≤100 ℃ Tsis txhob hloov pauv tam sim ntawd tshwj tsis yog hydrofluoric acid, concentrated phosphoric acid thiab muaj zog alkali.
Cam khwb cia hlau tsis muaj hauv ob sab phlu Siv kub raws li diaphragm valve cov khoom uas tsis yog-corrosive nruab nrab.
Stainless hlau unlined General corrosive media.
Txhim kho Diaphragm li qub
1. Ua ntej txhim kho lub diaphragm valve, ua tib zoo xyuas seb qhov kev khiav hauj lwm ntawm cov kav dej puas yog raws li qhov teev ntau ntawm kev siv lub valve, thiab cov kab noj hniav yuav tsum tau muab ntxuav kom tsis txhob muaj av los ntawm kev daig lossis ua rau cov khoom sib khi.
2. Tsis txhob pleev xim rau saum npoo ntawm cov roj hmab hauv ob sab phlu thiab roj hmab diaphragm nrog roj los tiv thaiv cov roj hmab los ntawm o thiab cuam tshuam rau lub neej kev pab cuam ntawm lub diaphragm valve.
3. Lub log lossis lub tshuab xa tawm tsis pub siv rau kev nqa, thiab kev sib tsoo yog nruj me ntsis txwv.
4. Thaum ua haujlwm lub diaphragm valve manually, yuav tsum tsis txhob siv lub auxiliary lever los tiv thaiv kev puas tsuaj rau cov tsav tsheb lossis cov khoom sib khi vim yog lub zog ntau dhau.
5. Diaphragm li qub yuav tsum tau muab cia rau hauv chav qhuav thiab qhov cua, thiab kev sib tsoo yog nruj me ntsis txwv.Ob qhov kawg ntawm lub diaphragm valve yuav tsum tau muab kaw, thiab qhov qhib thiab kaw qhov chaw yuav tsum nyob rau hauv lub xeev qhib me ntsis.
Txhim kho qhov tsis zoo ntawm cov diaphragm li qub
1. Kev ua haujlwm ntawm lub log tsis hloov pauv: ① Lub valve qia yog khoov ②Cov xov puas lawm ① Hloov lub valve qia ② Kho cov xov thiab ntxiv cov roj nplua nyeem
2. Lub pneumatic diaphragm valve tsis tuaj yeem qhib thiab kaw tsis tau: ①Cov cua siab tsawg dhau ② Lub caij nplooj ntoos hlav quab yuam loj dhau ③Cov roj hmab diaphragm puas lawm ① Ua kom cov cua nkag siab ② Txo lub caij nplooj ntoos hlav quab yuam ③ Hloov lub diaphragm
3. Cov dej ntws tawm ntawm qhov kev sib txuas ntawm lub cev lub cev thiab lub kaus mom: ①Txoj hlua txuas yog xoob ②Cov roj hmab txheej hauv lub valve lub cev tau tawg ① Tighten qhov txuas txuas ② Hloov lub valve lub cev
