Ukusungula kudosa phambili: I-TWS ihlathulula ngokunabileko iinzuzo zethekhnikhi ze-U-Section Flanged Wafer Butterfly Valve

I. Isingeniso somkhiqizo

IU-type soft seal butterfly valvesisisetjenziswa esisebenzako esiphezulu sokulawula nokuvala. Iphara yayo yokuvala eqakathekileko yamukela umklamo ohlukileko "womhlobo we-U". Isihlalo sevalvu sivame ukubunjwa ngokunembileko ngerabha yekhwalithi ephezulu (njenge-EPDM, NBR, PTFE, njll.) begodu sinesakhiwo sohlobo lwe-U. Ivalvu le incani ngobukhulu begodu ilula ngobunzima. Isetjenziswa khulu emaphayiphini wephethroliyamu, amakhemikhali, ukudla, imithi, ukwenza amaphepha, amandla wamanzi, imikhumbi, ukuphakelwa kwamanzi nokukhipha amanzi, ukucwengisisa, amandla nezinye iinkambo. Ingasetjenziswa njengethulusi lokulawula nelokuvimbela imihlobo ehlukileko yegesi evuvukako nengaguliko, amapayipi we-powder, amanzi, ama-semi-fluid kanye namaphayiphi wepuyere eqinileko.

II. Iimpawu ezikulu

1. Ukusebenza okuhle khulu kokuvala:OkuhlukilekoUmklamo wesihlalo sevalvu yomhlobo we-Uinomsebenzi wokubhadela ngokuzenzakalelako. Lokha ivalvu nayivaliweko, ipuleti le-butterfly kanye nesihlalo sevalvu yohlobo lwe-U zisesigabeni sokuphazamiseka, kusetjenziswa ukuguquguquka kwe-elastic yerabha ukufezekisa ukuvalwa “kokungavuzi”; lokha ivalvu nayivulwako, isihlalo sevalvu sisethwa kabutjha msinyana, lokho kwehlisa ukuguga begodu kuqinisekise ukuvalwa okuqinileko kweendlela ezimbili ngaphandle kokuvuza.

2. Ukusebenza okulula nokuguquguqukako:I-valve stem kanye ne-butterfly disc yamukela isakhiwo esinamandla esiphezulu sokuvikela ukuphapha, begodu ukudluliswa kubushelelezi. I-torque yokuvula nokuvala incani, iswitjhi iyarhaba, begodu ingasetjenziswa lula ngesibambo, igiya le-worm nofana i-pneumatic/electric actuator.

3. Ukujamelana nokugqwala nokuphila isikhathi esideisipani:Umzimba wevalvu ungenziwa ngensimbi ephosiweko, insimbi ethambileko nofana insimbi engagqwali, begodu ngaphakathi ifakwe irabha engagqwali. Isihlalo sevalvu yohlobo lwe-U akulula ukuguga nokudabuka. Ngitjho nangaphasi kwemibandela yokuvula nokuvala kanengi, ingagcina ukuthamba okuhle nokuvala, begodu ipilo yayo yokusebenza yinde khulu kunaleyo yesikoamavalvu we-butterfly welayini ephakathi.

4. Ibanga elibanzi lokusetjenziswa:ilungele amanzi, umoya, amafutha kanye nemidiya engagqwali. Izinga lokutjhisa lokusebenza liya ngezinto zokuvala (ngokuvamileko -10°C ukuya ku-120°C).

III. Isirhunyezo:

Ngokungavuzi kwayo, isikhathi eside sokuphila nokuthembeka, iU-type soft-sealing butterfly valveyisisetjenziswa esihle sokusika nokulawula erherhweni lamapayipi.I-TWSakusikho kwaphela ngokuvala okuhle kwamavalvu we-U-type butterfly, kodwana nangokuzinza nokuthembeka kweamavalvu wesangokunyeamavalvu wokuhlola– woke umugqa wemikhiqizo usezingeni eliphezulu.
