Ivalvu ye-Butterfly ehlezi ngerabha ene-EPDM yokuvala: Umbono opheleleko

**Amavalvu we-butterfly ahlelwe ngerabha anezivalo ze-EPDM: umbono opheleleko**

Amavalvu we-butterflyziingcenye eziqakathekileko eensetjenzisweni ezihlukahlukeneko zebubulo, ezihlinzeka ngokulawulwa kokugeleza okuphumelelako emapayipini. Hlangana nemihlobo ehlukilekoamavalvu wevithamini, amavalvu we-butterfly ahlezi ngerabha avela khulu ngebanga lomklamo wawo ohlukileko nokusebenza kwawo. Enye yezinto eziqakatheke khulu ezithuthukisiweko emkhakheni lo kukwamukelwa kwe-EPDM (ethylene propylene diene monomer) izivalo, okwenza ngcono ukusebenza nokuqina kwevalvu.

Iimvalo ze-EPDM zaziwa ngokujamelana kwazo kuhle khulu nokutjhisa, i-ozone kanye nobujamo bezulu, okwenza bona zilungele ukusetjenziswa okutlhoga ukuvalwa okuthembekileko ebujameni obubudisi. Lokha nayihlanganiswa emavalvuni we-butterfly ahlezi ngerabha, ama-seal we-EPDM anikela ngokuvala okuqinileko, ukunciphisa ubungozi bokuvuza nokuqinisekisa ukulawulwa kokugeleza okuhle. Lokhu kuqakatheke khulu emabubulweni afana nokuhlanzwa kwamanzi, ukucubungula amakhemikhali kanye neenhlelo ze-HVAC, lapho ukugcina ubuqotho behlelo kuqakathekile khona.

Amavalvu we-butterfly ahlezi ngerabhange-EPDM izivalo zinikela ngeenzuzo ezinengi. Kokuthoma, into ye-EPDM ingakghona ukujamelana namazinga womtjhiso ahlukileko, ngokuvamileko -40°C ukuya ku-120°C, okwenza bona ilungele kokubili ukusetjenziswa okutjhisako nokubandako. Kwesibili, ukuguquguquka kwesihlalo serabha kuvumela ukusebenza okutjhelelako, ukwehlisa i-torque etlhogekako ukuvula nokuvala ivalvu. Isici lesi asithuthukisi isipiliyoni somsebenzisi kwaphela, kodwana singezelela ipilo yomhlangano wevalvu.

Ukungezelela, umklamo we-butterfly valve ongasindi, ohlanganiswe nesivalo sayo esiqinileko se-EPDM, kuvumela ukufakwa nokugcinwa okulula. Abasebenzisi bangabuyisela isivalo msinyana ngaphandle kwesidingo samathulusi akhethekileko, ukuqinisekisa isikhathi esincani sokuphumula.

Ekuphetheni, amavalvu we-butterfly ahlezi ngerabha anezivalo ze-EPDM ajamele ubutjha obuqakathekileko ebuchwephesheni bokulawula ukugeleza. Ukuqina kwazo, ukujamelana nezinto zebhoduluko kanye nobulula bokutlhogomela kwenza bona zikhethwe khulu emisebenzini ehlukileko yebubulo. Njengombana ibubulo liragela phambili nokutjhuguluka, ukufunwa kweensombululo zamavalvu ezithembekileko nezisebenzako ngokungangabazeki kuzokukhula, ngaleyindlela kuqinise indima yamavalvu we-EPDM-sealed butterfly ebunjiniyeleni besimanjemanje.
