Qaab dhismeedkawaalka diaphragmaad ayuu uga duwan yahay kan caadiga ah.Waa nooc cusub oo waalka ah iyo nooc gaar ah oo ah waalka damin.Qaybteeda furitaanka iyo xidhitaankeeda waa diaphragm ka samaysan jilicsan Godka gudaha ee daboolka iyo qaybta wadista waa la kala saaraa, waxaana hadda si ballaaran loo isticmaalaa meelo kala duwan.Walalka diaphragm ee sida caadiga ah loo isticmaalo waxaa ka mid ah valves diaphragm caag ah, valves diaphragm-ka leh fluorine, valves diaphragm aan khadnayn, valves diaphragm caag ah.
Waalka diaphragm waxa uu ku qalabaysan yahay diaphragm dabacsan ama diaphragm la isku daray oo ku dhex jira jidhka waalka iyo daboolka waalka, qaybteeda xidhitaankeeduna waa qalab cadaadis ah oo ku xidhan diaphragm.Kursiga waalka wuxuu noqon karaa nooca weir ama nooc toos ah.
Faa'iidada diaphragm valve waa in habka hawlgalka uu ka sooco marinka dhexdhexaadka ah, taas oo aan hubinaynin oo kaliya nadiifinta dhexdhexaadiyaha shaqada, laakiin sidoo kale waxay ka hortagtaa suurtogalnimada dhexdhexaadinta dhuunta ee saameynaya qaybaha shaqada ee habka hawlgalka.Intaa waxaa dheer, shaabad gaar ah oo nooc kasta ah ayaa looga baahan yahay jirridda, marka laga reebo sifo badbaado ah oo lagu xakameynayo warbaahinta khatarta ah.
In waalka diaphragm, tan iyo dhexdhexaad ka shaqeeya waa xiriir la leh diaphragm iyo jidhka waalka, labaduba waxay isticmaali karaan noocyo kala duwan oo qalab kala duwan, sidaas darteed valve si fiican u koontarooli karaan noocyo kala duwan oo warbaahinta shaqada, gaar ahaan ku haboon kiimikaad daxaliyaha ama qaybo la hakiyey.dhexdhexaad ah.
Heerkulka shaqada ee waalka diaphragm waxaa inta badan xadidaya alaabta loo isticmaalo dahaarka diaphragm iyo waalka, cabirka heerkulka hawlgalkiisuna waa ilaa -50 ilaa 175 °C.Waalka diaphragm waxa uu leeyahay qaab dhismeed fudud waxana uu ka kooban yahay kaliya saddex qaybood oo waaweyn: jidhka waalka, diaphragm iyo shirka daboolka waalka.Waalka way fududahay in la kala diro oo si dhakhso ah loo dayactiro, beddelka diaphragm-ka waxa lagu samayn karaa goobta iyo wakhti gaaban gudaheed.
Walalka diaphragm:
Qalabka dahaarka (code), heerkulka hawlgalka (℃), dhexdhexaad ah oo ku habboon
Caag adag (NR) -10 ~ 85 ℃ Hydrochloric acid, 30% sulfuric acid, 50% hydrofluoric acid, 80% phosphoric acid, alkali, cusbada, xalinta biraha, sodium hydroxide, potassium hydroxide, xal saline dhexdhexaad ah, 10% Sodium hypochlorite , koloriin diiran, ammonia, khamriga intooda badan, acids organic iyo aldehyde, iwm.

Dhaldhalaalka ≤100℃ Iska ilaali isbeddelka heerkulka degdega ah marka laga reebo hydrofluoric acid, phosphoric acid oo xoog leh iyo alkali xooggan.
Ku shub birta bilaa dahaarka ah Isticmaal heerkulka sida uu qabo waalka diaphragm dhexdhexaad dhexdhexaad ah oo aan daxal lahayn.
Birta aan birta lahayn ee aan la daboolin Warbaahinta guud ee daxaleysiga.
Ilaalinta Valves Diaphragm
1. Kahor intaadan rakibin waalka diaphragm, si taxadar leh u hubi in xaaladaha shaqada ee dhuumaha ay waafaqsan yihiin xadka la cayimay ee isticmaalka waalka, iyo daloolka gudaha waa in la nadiifiyaa si looga hortago wasakhdu inay ku dhegto ama waxyeello u gaysato qaybaha xiritaanka.
2. Ha rinjiyin dusha sare ee lakabka dahaarka caagga ah iyo diaphragm caag dufan si aad uga ilaaliso caagga bararka oo saameeya nolosha adeegga waalka diaphragm.
3. Taayir-gacmeedka ama habka gudbinta looma oggola in loo isticmaalo qaadista, shilkuna si adag ayaa loo mamnuucay.
4. Markaad gacanta ku shaqaynayso waalka diaphragm, kabaalka kaaliyaha waa inaan loo isticmaalin si looga hortago burburka qaybaha wadista ama qaybaha xidhidhiyaha sababtoo ah qulqulka xad dhaafka ah.
5. Albaabada diaphragm waa in lagu kaydiyaa qol qalalan oo hawo leh, is dulsaarkuna waa mamnuuc.Labada daraf ee waalka diaphragm ee saamiyada waa in la xidhaa, qaybaha furitaanka iyo xidhidhkuna waa inay ahaadaan xaalad waxyar furan.
Xali khaladaadka caadiga ah ee valves diaphragm
1. Shaqaynta taayir-gacmeedku maaha mid dabacsan:
2. Waalka pneumatic diaphragm ma furi karo oo si toos ah uma xirmi karo: ①Cadaadiska hawadu aad ayuu u hooseeyaa
3. Diidashada xidhiidhka ka dhexeeya jidhka waalka iyo boodhka:
