Covpneumatic diaphragm tswj valvetxais yuav "elastic diaphragm + pneumatic diaphragm actuator" tsim. Powered los ntawm compressed cua, nws tau txais ib tug qauv pneumatic teeb liab ntawm 0.02-0.1MPa, tsav lub diaphragm mus deform thiab tshem tawm lub valve core, yog li hloov lub ntws channel cross-sectional cheeb tsam tswj qhov nruab nrab.
Ib txhij, lub diaphragm kiag li cais cov tub ntxhais valve los ntawm nruab nrab, tiv thaiv kom tsis txhob muaj paug thiab paug. Nws cov txiaj ntsig tseem ceeb yog nyob rau hauv "zero sab nraud to thiab corrosion tsis kam + qauv yooj yim": lub diaphragm tuaj yeem tiv taus cov kua qaub thiab alkali corrosion feem ntau, ua rau nws tsim nyog rau kev lag luam xws li tshuaj lom neeg, kev tiv thaiv ib puag ncig, thiab kev ua lag luam uas cuam tshuam rau cov kab mob sib kis tau yooj yim, thiab nws yuav tsum tsis muaj hluav taws xob.
GNEE Group yog cov chaw tsim khoom lag luam ntawm cov khoom lag luam, muab cov kev daws teeb meem valve thiab cov kev pabcuam customization rau cov neeg siv khoom thoob ntiaj teb.Valve Performance Guarantee - Kawm ntxiv Hnub no!

Pneumatic Diaphragm Tswj Valve Cov yam ntxwv
1. Diaphragm Structure: Lub diaphragm tswj valve txais lub diaphragm qauv, cais lub valve lub cev ntawm lub actuator, ua tiav ob qho tib si sealing thiab stability. Ib txhij, lub diaphragm zoo tiv thaiv corrosion thiab hnav ntawm tus actuator los ntawm cov kua nruab nrab, txhim kho lub valve lub durability.
2. High Adjustment Precision: Lub pneumatic diaphragm tswj valve muaj kev hloov kho siab, ua kom muaj kev tswj xyuas cov dej nruab nrab. Los ntawm kev hloov cov roj siab, lub valve qhib tuaj yeem hloov kho qhov tseeb, yog li ua tiav cov kev tswj hwm ntawm cov tsis xws li cov nqi ntws thiab siab ntawm cov kua nruab nrab.
3. Kev Ua Haujlwm Yooj Yim: Lub pneumatic diaphragm tswj valve yog yooj yim rau kev khiav lag luam. Lub valve qhib tuaj yeem hloov kho los ntawm kev tswj lub siab ntawm compressed cua los yog nitrogen. Nws kuj tseem muaj cov haujlwm hloov kho ntawm phau ntawv, tso cai rau kev siv phau ntawv thaum hloov kho tsis siv neeg.
4. Kev ruaj ntseg zoo: Lub pneumatic diaphragm tswj valve muaj kev ruaj ntseg zoo, tswj kev ua haujlwm ruaj khov nyob rau hauv ntau yam kev ua haujlwm. Tsis tas li ntawd, lub valve muaj kev tiv thaiv overload, cia li kaw lub valve nyob rau hauv cov ntaub ntawv ntawm overload los tiv thaiv cov cuab yeej los ntawm kev puas tsuaj.

Pneumatic Diaphragm Tswj Valve Ceev faj
1. Thaum siv pneumatic diaphragm tswj li qub, xyuas kom lub raj xa dej huv thiab tsis muaj kev tiv thaiv kom tsis txhob muaj cov khib nyiab thiab cov kab mob nkag mus rau hauv lub valve thiab cuam tshuam rau kev ua haujlwm ib txwm muaj.
2. Thaum lub sij hawm installation thiab siv, nruj me ntsis raws li cov chaw tsim tshuaj paus cov lus qhia rau kev khiav hauj lwm thiab txij nkawm. Tsis tu ncua xyuas lub valve thiab cov kav dej rau cov dej xau thiab thaiv, thiab daws txhua yam teeb meem tam sim ntawd kom ntseeg tau tias kev ua haujlwm ib txwm muaj thiab txuas ntxiv nws lub neej kev pabcuam.
3. Yog tias muaj qhov txawv txav thaum siv, nres lub tshuab tam sim ntawd, tshuaj xyuas thiab kho qhov teeb meem kom ntseeg tau tias muaj kev nyab xeeb thiab txhim khu kev qha valve ua haujlwm thiab txuas nws lub neej kev pab cuam.
