Iivalvu zebhabhathane zizinto ezibalulekileyo kwiinkqubo zemibhobho yemizi-mveliso, kwaye ukusebenza kwazo kuxhomekeke kakhulu kwimilo efanelekileyo yebholti. Esi sikhokelo sinika iinkcukacha ezineenkcukachaitshathi yebholthi yevalvu yebhabhathanekwiivalvu zeflange, i-wafer, intsimbi engatyiwayo, kunye ne-carbon steel. Nokuba ungunjineli, ingcali yokuthenga, okanye ingcali yokulungisa, ukuqonda iinkcukacha zebolt kuqinisekisa ukusebenza kwevalvu ngokukhuselekileyo nangokufanelekileyo.
Kutheni iitshati zeBolt zibalulekile kwiivalvu zeButterfly
Ukubholta ngumqolo wokuqina kwendibano yevalvu. Ubungakanani bebolthi obungalunganga, izinto, okanye i-torque kunokukhokelela ekuvuzeni, ukungasebenzi kakuhle kwevalvu, okanye nokuba inkqubo ayisebenzi.itshathi yebholthi yeeflangeokanye iivalvu zebhabhathane zilinganisa:
- Ubukhulu beBolt(ububanzi, ubude, uhlobo lomsonto).
- Ukuhambelana kwezinto eziphathekayo(intsimbi engatyiwayo, intsimbi yekhabhoni).
- Amaxabiso eTorqueukuze kufunyanwe ukutywinwa okufanelekileyo.
Ngokubaiivalvu zebhabhathane ezisicabakwayeiivalvu zebhabhathane ezisicaba, iitshathi zebholithi ziyahluka ngokusekwe kubukhulu bevalvu, umlinganiselo woxinzelelo, kunye nemigangatho yeflange (ANSI, DIN, JIS).
Itshati yeBolt yeFlange Butterfly Valve
Iinkcukacha ze-ANSI Flange Bolt
Iiflange ze-ANSI B16.5 zisetyenziswa kakhulu eMntla Melika. Apha ngezantsi kukho indlela elula yokwenza oku.itshathi yebholthi yeflangekwiivalvu zebhabhathane zeKlasi 150 kunye neKlasi 300:
| Ubungakanani beValve (ii-intshi) | Ubungakanani beBolt | Ububanzi beBolt (ii-intshi) | Ubude beBolt (ii-intshi) |
| 2″ | 4 | 0.5″ | 2.5″ |
| 6″ | 8 | 0.75″ | 3.5″ |
| 12″ | 12 | 1″ | 4.5″ |
Amanqaku ezinto:
- Iivalvu zebhabhathane zentsimbi engenasiciNgokuqhelekileyo zisebenzisa iibholithi ze-ASTM A193 B8 ukumelana nokugqwala.
- Iivalvu zebhabhathane zentsimbi yekhabhonidibanisa neebholiti ze-ASTM A307 ukuze zisetyenziswe ngamandla aphezulu.
Itshati yeBolt yeWafer Butterfly Valve
Iivalvu zebhabhathane zeWaferzikhaphukhaphu kwaye zixhomekeke kwiibholithi zeflange ukuze zicinezelwe.itshathi yebholtiigxile kwi:
- Ubude bebholthi:Kufuneka ijikeleze umzimba wevalvu kunye neeflanges.
- Imikhono yesithuba:Kudla ngokufuneka ukuze kuthintelwe ukuqina kakhulu.
| Ubungakanani beValve (ii-intshi) | Ubude beBolt (ii-intshi) | I-Torque (lb-ft) |
| 4″ | 3.0″ | 45–50 |
| 10″ | 5.5″ | 90–100 |
| 16″ | 7.0″ | 150–170 |
Ingcebiso:Soloko uqinisekisa ubude bebholithi ngeumenzi weevalvu zebhabhathaneukuze kuthintelwe ukungangqinelani.
Ukukhethwa kwezinto zeBolt: Intsimbi Engagqwaliyo vs. Intsimbi yeCarbon
Iibholiti zeValve yeButterfly yeNtsimbi Engagqwaliyo
- Amanqanaba:I-ASTM A193 B8 (304/316 SS) yokumelana nokugqwala okuphezulu.
- Izicelo:Amashishini eekhemikhali, aselwandle, okanye asebenza ngokutya.
- I-Torque:Kufuneka i-torque ephantsi xa kuthelekiswa nentsimbi yekhabhoni.
Iibholiti zeValve yeBhabhatha yentsimbi yeCarbon
- Amanqanaba:I-ASTM A307 okanye i-A325 yamandla aphezulu okutsalwa.
- Izicelo:Iinkqubo zeoyile, igesi, kunye nobushushu obuphezulu.
- Ukwaleka:Ifakwe nge-galvanized okanye nge-zinc ukuthintela ukugqwala.
Indlela yokukhetha umenzi wevalvu yebhabhathane ethembekileyo eTshayina
I-China ilawula imveliso yeevalvu kwihlabathi liphela, kodwa umgangatho uyahluka. Izinto eziphambili xa ukhethaUmenzi wevalvu yebhabhathane yaseTshayina:
1. Iziqinisekiso:I-ISO 9001, i-API 609, i-CE.
2. Ukulandeleka kwezinto:Iingxelo zovavanyo lweMill zentsimbi engatyiwayo/ekhabhoni.
3. Iitshathi zeBolt ezenziwe ngokwezifiso:Ukwazi ukubonelela ngeenkcukacha zebholithi ezihambelana nevalvu.
IiMarike eziPhambili:
- Iivalvu zebhabhathane zeWaferkwiinkqubo ze-HVAC.
- Iivalvu zebhabhathane zeFlangekwizityalo zokunyanga amanzi.
