Faa'iidooyinka badan ee valves kubbadda PVC ayaa ka dhigaya doorasho aad u fiican oo loogu talagalay codsiyada kala duwan. Waxaa jira arrimo gaar ah oo ay tahay in la tixgeliyo marka la go'aansanayo in la iibsado valve kubbadda, gaar ahaan aWaalka kubbadda ee PVC. Iyadoo PVC ay awood u leedahay in ay u adkeyso xaalado kala duwan, isku dheelitirka saxda ah ee u dhexeeya valve iyo codsiga ayaa aad muhiim u ah marka la dooranayo valve kubbadda PVC.

naqshadeynta godka
Inkasta oo qaabka laba-geesoodka ah ee PVC-ga uu yahay midka ugu caansan, waxaa jira naqshado kale oo dalool ah oo gacan ka geysan kara hagaajinta waxtarka codsiga. Naqshadaynta saddex geesoodka ah waxaa ka mid ah qaabaynta T-port iyo L-port ee codsiyada halka socodka dareeraha la isku daray, la qaybiyay, lagana leexiyay. Naqshadeynta daloolka ayaa aad u caawineysa dareerayaal badan iyo noocyada kala duwan ee socodka.

fahamka warbaahinta
Mid ka mid ah sababaha horumarinta valves kubbadda PVC ee 1950-yadii waxay ahayd warbaahin u baahan maarayn gaar ah. Xirmooyinka kubbadda PVC waxay ku habboon yihiin warbaahinta wasakhaysan sida biyaha cusbada, acids, alkalis, xalalka milixda iyo dareerayaasha organic, kuwaas oo dhaawici kara alaabta kale. Fahamka sifooyinka dhexdhexaadinta waa arrin muhiim ah oo ka mid ah habka xulashada.

Isku xidhka heerkulka
Heerkulka ayaa qayb weyn ka ah codsiyo badan oo wax soo saar ah waana in si taxadar leh loo tixgeliyo marka la dooranayo valve kubbadda PVC. Qaab dhismeedka kiimikada ee maaddada PVC waa arrin hagaya markaad dooranayso kubbadda kubbadda PVC, maaddaama PVC ay u nugul tahay inay hoos u dhigto oo ay isbeddelaan xaaladaha qaarkood.

saamaynta stress
Si la mid ah heerkulka, cadaadisku wuxuu si xoog leh u saameyn karaa ku habboonaanta aWaalka kubbadda ee PVCcodsi. Xaaladdan oo kale, qaabka PVC wuxuu sidoo kale noqon karaa qodobka go'aaminta.

gabagabadii
Waalka kubbadda ee PVC ama polyvinyl chloride waa balaastiig bannaanka saaran oo leh kubbad dabaasha oo dalool leh taasoo joojisa socodka warbaahinta iyadoo kubbadda u rogi doonta rubuc wareeg ah.
Xudunta u ahWaalka kubbadda ee PVCwaa kubad wareegeysa, oo loo yaqaan kubad wareegeysa. Jirridka ku yaalla xagga sare ee kubbaddu waa habka kubbadda roga, kaas oo lagu samayn karo gacanta ama si toos ah, iyadoo ku xidhan naqshadda waalka.
Noocyada kala duwan ee tuubooyinka kubbadda PVC waxaa loogu talagalay inay la kulmaan codsiyada gaarka ah. Waxa loo kala saaray tiro dekedo ah, nooca fadhiga, isu-ururinta jidhka, marinnada kubbadda iyo cabbirka boodhka.
Qalabka aasaasiga ah ee valve kubbadda PVC waa chloride polyvinyl, kaas oo ah resin vinyl ah. Erayga PVC waxaa loola jeedaa agabyo kala duwan oo PVC ah oo leh awoodo kala duwan, astaamo iyo astaamo kala duwan.
Isticmaalka caadiga ah ee fiilooyinka kubbadda PVC waa in la gooyo ama lagu xiro warbaahinta dhuumaha iyo xakamaynta dareeraha iyo nidaaminta.
