Bawuloli masu duba waferAna kuma san su da bawuloli na baya-bayan, bawuloli na baya-bayan, da bawuloli na baya-bayan. Waɗannan nau'ikan bawuloli ana buɗe su kuma a rufe su ta atomatik ta hanyar ƙarfin da kwararar matsakaiciyar kanta ke samarwa a cikin bututun, wanda ke cikin wani nau'in bawuloli na atomatik.
Bawul ɗin duba shine ya dogara da kwararar matsakaiciyar kanta kuma yana buɗewa da rufe murfin bawul ta atomatik, wanda ake amfani da shi don hana bawul ɗin komawa baya na matsakaici, wanda kuma aka sani da bawul ɗin duba, bawul ɗin duba, bawul ɗin dawowa, da bawul ɗin matsin lamba na baya. Bawul ɗin duba yana cikin wani nau'in bawul na atomatik, babban aikinsa shine hana kwararar kafofin watsa labarai, hana juyawar famfo da injin tuƙi, da kuma fitar da kafofin watsa labarai na kwantena. Hakanan ana iya amfani da bawul ɗin duba don ba da matsin lamba na iya tashi zuwa fiye da matsin tsarin tsarin taimako don samar da bututun samar da kayayyaki. Ana iya raba bawul ɗin duba zuwa bawul ɗin duba lilo (bisa ga tsakiyar juyawar nauyi) da bawul ɗin duba ɗagawa (yana motsawa tare da axis).
Da farko, amfani da bawul ɗin duba bawul ɗin da aka sanya a cikin tsarin bututun, babban aikinsa shine hana kwararar kafofin watsa labarai, bawul ɗin duba wani nau'in bawul ne na atomatik wanda ya dogara da matsin lamba na kafofin watsa labarai don buɗewa da rufewa. Bawul ɗin duba manne ya dace da matsin lamba na asali PN1.0MPa ~ 42.0MPa, Class150 ~ 25000, diamita na asali DN15 ~ 1200mm, NPS1/2 ~ 48, zafin aiki -196 ~ 540 ℃ na bututun mai daban-daban, waɗanda ake amfani da su don hana kwararar kafofin watsa labarai komawa baya.

Na huɗu, halayen tsarin bawul ɗin duba tsunkule
1. Tsawon tsarin gajere ne, tsawon tsarinsa shine kawai 1/4 ~ 1/8 na bawul ɗin duba flange na gargajiya.
2. ƙaramin girma, nauyi mai sauƙi, nauyinsa kawai bawul ɗin duba flange na gargajiya 1/4 ~ 1/2
3. matsewar bawul ɗin yana rufewa da sauri, matsin lamba na guduma ruwa ƙanana ne
4. Ana iya amfani da bututun kwance ko na tsaye, mai sauƙin shigarwa
5. Hanyar kwarara mai santsi, ƙarancin juriya ga ruwa
6. Aiki mai mahimmanci, kyakkyawan aikin rufewa
7. Faifan bugun yana da gajere, tasirin rufewa yana da ƙarami
8. Tsarin gabaɗaya yana da sauƙi kuma mai sauƙi, kuma siffar tana da kyau
9. Dogon rai da aiki mai inganci
biyar. Aikin rufewa na bawul ɗin duba wafer. Bawul ɗin duba wafer mai laushi zai iya cimma sifili na ɓuɓɓuga, amma bawul ɗin duba wafer mai tauri ba bawul ɗin zubar da sifili ba ne. Yana da wani adadin ɓuɓɓuga. Dangane da ƙa'idar dubawa ta API598, ga bawul ɗin duba tare da wurin zama na ƙarfe, don girman DN100, ƙimar ɓuɓɓuga ruwa a minti ɗaya shine 12CC.
