Madow/Cagaar PTFE/FPM + EPDM Rubber Valve Kursiga Kursiga Valve Balanbaalista
PTFE + EPDM kuraasta caagga ah ee la isku daray ee ay soo saartay SML ayaa si weyn loogu isticmaalaa dharka, xarunta korantada, petrochemical, kululaynta iyo qaboojiyaha, dawooyinka, dhismaha maraakiibta, birta, warshadaha iftiinka, ilaalinta deegaanka iyo meelaha kale.
Waxqabadka badeecada: caabbinta heerkulka sare, caabbinta acid wanaagsan iyo alkali iyo caabbinta saliidda; leh adkeysi soo kabasho wanaagsan leh, adag oo waara iyada oo aan dareerin.
PTFE+EPDM
Xadhkaha Teflon (PTFE) waxa uu dulsaaraa EPDM kaas oo ku xidhan giraan adag oo phenolic ah oo ku yaala wareega kursiga dibadda. PTFE waxay ku fidsan tahay wejiyada kursiga iyo bannaankaba dhexroorka shaabadda flange, oo si buuxda u daboolaya lakabka elastomer-ka ee EPDM ee kursiga, kaas oo siiya adkeysi loogu xirayo afkoda waalka iyo saxanka xiran.
Heerkulka: -10°C ilaa 150°C.
Budada PTFE (Polytetrafluoroethylene)
PTFE (Teflon) waa polymer-ka ku salaysan fluorocarbon oo caadiyan ah kan ugu adkaysiga badan kiimikaad ee balaastikada oo dhan, iyadoo ilaalinaysa sifooyin heer sare ah oo kuleyl iyo koronto ah. PTFE sidoo kale waxay leedahay iskudhaf hoose oo is jiid jiid ah sidaa darteed waxay ku habboon tahay codsiyo badan oo qulqulka hooseeya.
Walaxdani maaha -wax wasakhaysan oo ay aqbasho FDA ee codsiyada cuntada. Inkasta oo sifooyinka farsamada ee PTFE ay hooseeyaan, marka la barbardhigo balaastikada kale ee la farsameeyey, hantidoodu waxay ahaanayaan kuwo faa'iido leh oo ka badan heerkul ballaaran.
Heerkulka: -38°C ilaa +230°C.
Midabka: cad
Xadhkaha garaaca: 0%

Lagu dhisay heerar sax ah, fayodhowrkeena isku-darka ah ee balabaalisada xidhidhiyaha xidhidhiyaha ayaa daboolaya cabbir balaadhan oo u dhexeeya DN50 ilaa DN600, taas oo ka dhigaysa kuwo ku habboon shuruudaha tuubooyinka kala duwan. Codsiga xidhitaannadan siddooyinku aad ayay uga fog yihiin filashada caadiga ah, oo koobaysa qaybaha sida dunta, korontadda, warshadaha batroolka, kulaylinta iyo qaboojiyaha, soosaarka dawooyinka, dhisidda maraakiibta, biraha, warshadaha iftiinka, ilaalinta deegaanka, iyo in ka badan. Adeeggoodu wuxuu iftiimiyaa xaaladaha u baahan iska caabin heerkul sare ah, halkaas oo xalalka xiritaanka caadiga ah ay xumaadaan. faylalka alaabadayada waxaa ka mid ah Wafer Type Centerline Soft Seling Butterfly Valve iyo Pneumatic Wafer Butterfly Valve, labadaba waxaa lagu kala soocaa xiriirkooda wafer iyo flange dhamaadka. Wax-soo-saarkan waxa kaabaya nooca lugaha ee labanlaabka usheeda dhexe ee balastareedka aan lahayn pin, taasoo muujinaysa sida ay nooga go'an tahay bixinta ammaan, la isku halayn karo, iyo dayactir - hawlgallo bilaash ah. Isku dhafka PTFE + EPDM caag isku dhafan ee kuraasta waalka kaliya ma wanaajineyso cimriga iyo cimri dhererka valvesyada laakiin sidoo kale waxay si weyn u yaraynaysaa khatarta daadinta, hubinta shaabad adag oo u taagan tijaabada wakhtiga iyo xaaladaha shaqada. Haddi aad kormeerayso hawlaha xarunta korontada, aad ku dhex soconayso qalafsanaanta muuqaalka batroolka, ama hubinta habsami u shaqaynta hababka dawooyinka, fayodhowrkayada isku-dhafka ah ee balaalista valve xidhitaanka giraanta waxay u taagan tahay ilaaliyahaaga hufnaanta iyo isku halaynta.
