(1) Amavalvu ebhola womoya
I-valve yebhola yomoya iqukethe i-valve yebhola kanye ne-actuator yomoya.Ngokuvamile idinga ukusetshenziswa ngokuhambisana nezinsiza ezihlanganisa i-valve kazibuthe, i-FRL yokwelashwa komoya, ukushintsha komkhawulo, kanye nesibeka endaweni ukuze ilawulwe kude nasendaweni kanye nokuthi ivulwe futhi ivalwe egumbini lokulawula.Ithuthukisa ukuphepha, yonga kakhulu izindleko zezinsiza zabantu kanye nesikhathi, futhi yenza ukulawula okwenziwa ngesandla esizeni, ngaphezu komhlabathi nasezindaweni eziyingozi kungasadingeki.
(2) Izigaba zamavalvu ebhola womoya
Ngokusho kokuqukethwe, ama-valve ebhola womoya angahlukaniswa abe ama-valve ebhola womoya ensimbi engagqwali, ama-valve ebhola womoya wepulasitiki, ama-valve ebhola womoya womoya, ama-valve ebhola we-carbon steel pneumatic ball, ama-valve ebhola womoya wensimbi, njll.
Ngokwemodi yokuxhuma, ama-valve ebhola womoya angahlukaniswa abe ama-valve ebhola omoya ane-flanged, i-screw thread ye-pneumatic ball valve, ama-valve womoya ashiselwe, njll.
Ngokusho kwengcindezi, ama-valve ebhola womoya angahlukaniswa abe ama-valve ebhola womoya ocindezelayo ophansi, ama-valve ebhola womoya womfutho ophakathi nendawo kanye namavalvu ebhola womoya womfutho ophezulu.
Ngokuya kwendawo yesiteshi, ama-valve ebhola womoya angahlukaniswa abe ama-valve ebhola womoya, ama-valve ebhola womoya anezindlela ezintathu kanye nama-valve webhola womoya we-right angle.
Ngokwezici zebhola, ama-valve ebhola womoya angahlukaniswa abe ama-valve ebhola antantayo nama-valve ebhola e-trunnion.
Ibhola elintantayo
Ibhola le-valve yebhola elintantayo liyantanta.Ngaphansi kwemiphumela yokucindezela okuphakathi, ibhola lizogudluka futhi licindezelwe ngokuqinile endaweni yokuvala yokuphela kwe-outlet ukuze kuqinisekiswe ukusebenza kokuvala kokuphela kokuphumayo.
Ibhola elilungisiwe
Ibhola le-trunnion ball valve ligxilile, futhi ngeke lishintshe ngemva kokucindezelwa.Wonke ama-valve ebhola e-trunnion anesihlalo se-valve esintantayo.Ngaphansi kwemiphumela yokucindezela okuphakathi, i-valve iqala ukuhamba ukuze yenze indandatho yokuvala icindezelwe ebholeni ukuze kuqinisekiswe ukusebenza kokuvala.
(3) Ama-valve amabhola kagesi
I-valve yebhola kagesi yakhiwe i-actuator kanye ne-valve yebhola.Kuwuhlobo lwedivayisi esetshenziselwa amapayipi kumshini wokuzenzakalelayo wezimboni nokulawula inqubo.Ukucacisa, ngokuvamile isetshenziselwa isilawuli esikude sokuvala imidiya yamapayipi.
Ngokwencazelo ye-valve yebhola kagesi ku-"Glossary of terms for valves", i-valve yebhola kagesi iwuhlobo lwama-valve ama-disc awo (amabhola) aqhutshwa isiqu se-valve, bese ezungeza i-axis ye-valve.Ama-valve amabhola kagesi asetshenziswa kakhulu ekunqamuleni nasekungeneni emithonjeni yezindaba, noma asetshenziselwa ukulawula nokulawula imidiya kumapayipi.Ngokuqondene ne-valve yebhola evalwe ngokuqinile emise okwe-V, kukhona amandla aqinile okugunda phakathi kwebhola elimise okwe-V kanye nesihlalo sevalvu yensimbi esenziwe ngokumboza nge-carbide enosimende.
(4) Ukuqhathaniswa phakathi kwamavalvu ebhola womoya kanye namavalvu amabhola kagesi
Izindleko
Ivalve yebhola yomoya inomthwalo osindayo, kodwa ishibhile kunevalve yebhola kagesi.Ngakho, ukusebenzisa ama-valve ebhola womoya kunganciphisa izindleko zobunjiniyela.
Ukuphepha kokusebenza
Abasebenzisi abasebenzisa i-valve yebhola yomoya bangavula noma bavale ivalvu.Lapho i-valve yebhola kagesi ingenawo amandla, ingahlala kuphela endaweni yayo, okuveza ukuthi i-valve yebhola yomoya inezinzuzo ezinkulu ekuphepheni.Ngoba uma i-valve yebhola kagesi iphelelwa amandla, izovala ukuze kugwenywe i-backset yesihlungi nokuchitheka kwayo.I-valve yebhola yomoya ayidingi ugesi, kuyilapho i-valve yebhola kagesi isebenzisa u-220V noma isigaba sesithathu se-460V.Ngakho-ke, i-valve yebhola kagesi iyingozi kakhulu endaweni emanzi, kanti i-valve yebhola yomoya ayithinteki endaweni emanzi.Mayelana nokugcinwa, kulula ukugcina i-valve yebhola ye-pneumatic ngoba kunengxenye eyodwa kuphela ehambayo.I-actuator kagesi ye-valve yebhola kagesi idinga ukunakekelwa ochwepheshe ngenxa yezingxenye eziningi ze-actuator kagesi.
Ukusebenza
I-valve yebhola yomoya ingakwazi ukuzivumelanisa nomthwalo ogcwele njalo.I-valve yebhola kagesi inqunyelwe umthamo wokulayisha wamamotho kanye nezikhathi ezinkulu zokuqalisa ngehora.
Imijikelezo yokuphila
I-valve yebhola yomoya inomjikelezo wempilo ende enezenzo ezingaba yizigidi ezi-2.Izinga lokusebenzisa eliphindaphindayo le-valve yebhola lomoya lingalawulwa ngokunembile, elingacishe lifinyelele ku-0.25%.
Ukumelana nokugqwala
I-valve yebhola yomoya ene-epoxy coating ngaphakathi nangaphandle kwe-actuator yomoya inokuguquguquka okukhulu endaweni yokusebenza.Ingakwazi ukuzivumelanisa nendawo yokusebenza embi njengokuvutha, ukuqhuma, uthuli, i-ferromagnetic, i-radioactive, imvelo edlidlizayo, njll.
Ezinye izici
Uma i-valve yebhola yomoya ingasebenzi kahle, ingalungiswa noma ishintshwe ngaphandle kwamandla noma imithombo yomoya.Mayelana nokugcinwa, i-valve yebhola ye-pneumatic ayidingi amafutha, kanti i-valve yebhola kagesi idinga inani elikhulu lamafutha.Mayelana nokusebenza okwenziwa ngesandla, i-valve yebhola ye-pneumatic ingasebenza ngaphandle kwamandla.Mayelana nesivinini, i-valve yebhola yomoya isebenza nezimpendulo ngokushesha ukuze ilungise ngokufanele.Ijubane le-valve yebhola kagesi lihlala njalo futhi alikwazi ukushintshwa.
