Ivalve yebhabhathane eqinileyo etywiniweyo ephindwe kabiniyintsimbi ukuya kwintsimbi etywiniweyo.Ikwanokuba yintsimbi yokutywina intsimbi ukuya kwintsimbi etywiniweyo okanye yentsimbi engenastainless ngentsimbi yokutywina kwintsimbi etywiniweyo.Ukongeza kwindlela yokuqhuba umbane, ivalve yebhabhathane eneendlela ezimbini eqinileyo nayo inokuqhutywa ngesandla, ipneumatically, njl.
Idiski yeIndlela ezimbini zentsimbi seal butterfly valveifakwe kwi-diameter yecala lombhobho.Kwi-cylindrical channel ye-butterfly valve body, i-disc ijikeleza i-axis, kwaye i-angle yokujikeleza iphakathi kwe-0 ° kunye ne-90 °.I-valve ivuleke ngokupheleleyo xa i-disc ijikeleza kwi-90 °.
Ihlelwa ngokwendlela yolwakhiwo: yahlulwe yaba ivelufa yebhabhathane yokutywina ephakathi, ivalve yebhabhathane yokutywina enye, ivalve yebhabhathane yokutywina ephindwe kabini kunyeezintathu eccentric ukutywina butterfly valve.
Ihlelwa ngokutywinwa kwezinto ezingaphezulu: inokohlulwa ibe ziindlela ezimbini eziqinileyo zokutywina ibhabhathane iivalvu, ubuso obutywinayo buqulunqwe ngezinto ezithambileyo ezingezizo ezentsimbi okanye izinto eziqinileyo zesinyithi kwizinto ezithambileyo ezingezizo ezentsimbi;kwaye yahlulahlulwe yaba yintsimbi eqinileyo yokutywina iivalvu zebhabhathane, ubuso obutywinayo buqulunqwe ngezinto eziqinileyo zentsimbi ukuya kwizinto ezinzima zentsimbi.
Ukugcinwa, ukuFakelo kunye nokuSetyenziswa
1. Zombini iziphelo zevalve ziya kuvalwa kwaye zigcinwe kwigumbi elomileyo nelinomoya.Iya kujongwa rhoqo ukugcinwa ixesha elide.
2.I-valve iya kuhlanjululwa ngaphambi kokufakwa ukuphelisa iziphene ezibangelwa ngexesha lokuthutha.
3. Ngethuba lofakelo, amanqaku kwivalve kufuneka ahlolwe.Kwaye ingqwalasela eyodwa iya kuhlawulwa ukuba ulwalathiso lokuhamba kwe-medium luhambelana naloo nto iphawulwe kwivalve.
4. Kwiivalvu zebhabhathane ezine-actuator yombane, kuya kuqatshelwa ukuba umbane odityanisiweyo wonikezelo lwamandla kufuneka uhambelane naloo ncwadana yesixhobo sombane.
Iimpazamo ezinokwenzeka, oonobangela kunye neendlela zokuphelisa
1. Ukuvuza kwi-filler
Ukuba amantongomane eplate yokupakisha yokupakisha awaqiniswanga okanye aqiniswe ngokungalingani, amantongomane angaqiniswa ngokufanelekileyo.Ukuba ukuvuza kuyaqhubeka, ubuninzi bokupakisha bunokwanela.Ngeli xesha, ukupakishwa kunokulayishwa kwakhona kwaye emva koko uqinise amantongomane.
2. Ukuvuza kwindawo yokutywina yevalvu yomzimba kunye nediski yepleyiti
1) Coca ubumdaka obufakwe phakathi kweendawo zokutywina.
2) Ukuba indawo yokutywina yonakalisiwe, phinda ugaye okanye umatshini kwaye ugaye umzimba we-valve kwakhona emva kokulungiswa kwe-welding.
I-3) Ukuba indawo ye-eccentric ayifanelekanga, lungisa indawo ye-eccentric kwindawo efanelekileyo ngexesha lofakelo.
