Ukuxilongwa kwephutha kanye nesu lokuvikela lokuvikela ama-valve eglobhu kagesi e-flange
Abstract: Njengengxenye ebalulekile yezinhlelo zokulawula uketshezi, ukusebenza okuphephile, okuthembekile, futhi okuzinzile kwama-valve eglobhu e-flange kagesi kuthinta ngokuqondile ukusebenza okuvamile kwalo lonke uhlelo. Kodwa-ke, ekusebenzeni okungokoqobo, ama-valve eglobu kagesi e-flange angase ahlangabezane nezinkinga ezihlukahlukene ezithinta ukusebenza kwawo kanye nempilo yesevisi. Lesi sihloko sihlola ukuxilongwa kwephutha kanye namasu okuvikela okulondoloza ama-valve eglobhu kagesi e-flange, okuhloswe ngawo ukuhlinzeka ngereferensi ewusizo yobunjiniyela nezisebenzi zezobuchwepheshe.
1,Isingeniso
Ama-valve eglobu kagesi e-flange asetshenziswa kabanzi ezimbonini ezifana ne-petroleum, amakhemikhali, i-metallurgy, namandla, anezici zesakhiwo esilula, ukusebenza kahle kokuvala, nokusebenza okulula. Kodwa-ke, ngesikhathi sokusebenza isikhathi eside, ngenxa yezici ezihlukahlukene, ama-valve embulunga kagesi ye-flange angase abe namaphutha njengokuvuza, ukuminyana, nokungaguquguquki, okuholela emiphumeleni engathi sína njengokuvalwa kwemishini kanye nezingozi zokukhiqiza. Ngakho-ke, ukwazi ukuxilongwa kwephutha kanye namasu okuvikela okugcina ama-valve eglobhu kagesi e-flange kubaluleke kakhulu.
2,Izinhlobo nezimbangela zamaphutha kuma-valve eglobhu kagesi e-flange
1. Ukuvuza
Ukuvuza kungenye yamaphutha avame kakhulu ama-valve eglobhu kagesi e-flange, futhi izizathu eziyinhloko yilezi ezilandelayo:
(1) Ukugqokwa noma ukulimala endaweni yokuvala: Ngesikhathi sokusetshenziswa isikhathi eside, indawo evalayo isengozini yokuguguleka okuphakathi nendawo, okuholela ekwehleni kokuvala ukusebenza.
(2) Ukuguga kokugcwalisa: Isigcwalisi siyingxenye ebalulekile yokuqinisekisa ukusebenza kokuvala ama-valve eglobhu kagesi e-flange. Ngemuva kokusetshenziswa isikhathi eside, ijwayele ukuguga, ukuguga, nokuvuza.
(3) Ukuguqulwa kwekhava yevalvu: Ngenxa yezici zangaphandle ezifana nezinga lokushisa nokucindezela, umzimba wevalvu noma ikhava yevalvu ingase yonakale, okuholela ekwenyukeni kwegebe phakathi kwezindawo zokuvala futhi kubangele ukuvuza.
2. Wabhajwa
Ukubonakaliswa okuyinhloko kwe-electric flange shut-off valve jamming ukuthi i-valve ayikho endaweni noma ayikwazi ukuvulwa futhi ivalwe, futhi izizathu zimi kanje:
(1) Ukungqubuzana phakathi kwesiqu se-valve nokupakishwa: Ukungqubuzana isikhathi eside phakathi kwesiqu se-valve nokupakishwa kubangela ukuguga, okuholela ekwenyukeni kokungqubuzana phakathi kwesiqu se-valve nokupakishwa.
(2) Izinhlayiya eziphakathi nendawo: Izinhlayiya eziphakathi nendawo zijwayele ukubhajwa phakathi kwediski ye-valve nesihlalo sevalvu, okwenza ivalvu igxumeke.
(3) Ukukalwa kwangaphakathi kwamavalvu: Ukungcola endaweni ephakathi nendawo ngaphakathi kwevalvu, ukwakha ukukala, ukunciphisa imigudu yangaphakathi yevalvu futhi kubangela ukuba ivalvu igxumeke.
3. Ukunyakaza okungaguquki
Ukungaguquguquki kwesenzo se-valve yeglobu kagesi ye-flange kubonakaliswa ikakhulukazi isivinini sokushintsha kancane kanye ne-torque enkulu, futhi izizathu zimi kanje:
(1) Ukungasebenzi kahle kwezimoto: Injini eku-actuator kagesi ilimele noma ukusebenza kwayo kuncishisiwe, okuholela ekuphumeni kwetorque enganele.
(2) Ukwehluleka kwendlela yokudlulisela: Indlela yokudlulisela igugile, iyaxega noma ilimele, okuthinta isivinini sokuvula nokuvala kanye ne-torque ye-valve.
(3) Isignali yokulawula okungavamile: Ukungasebenzi kahle kwesistimu yokulawula, okubangela amasignali okulawula angazinzile kanye nokusebenza kwe-valve okungenakuguquguquka.
3,Indlela yokuxilongwa kwephutha yama-valve eglobhu kagesi e-flange
1. Indlela yokubuka
Ngokubheka isimo sokusebenza, isimo sokuvuza, kanye nezinga lokupakisha ukuguga kwe-valve, thola ukuthi kukhona yini ukungasebenzi kahle ku-valve.
2. Indlela yokuxilongwa ezwakalayo
Kusetshenziswa izinzwa zomsindo ukuqoqa amasignali omsindo phakathi nokusebenza kwamavalvu, kuhlaziya izici zomsindo ukuze kutholwe ukuthi i-valve inephutha yini.
3. Indlela yokuthola izinga lokushisa
Gada izinguquko zokushisa ngesikhathi sokusebenza kwamavalvu ngezinzwa zokushisa, hlaziya izindawo zokushisa ezingavamile, futhi uhlole imbangela yamaphutha.
4. Indlela yokuthola ukudlidliza
Kusetshenziswa izinzwa zokudlidliza ukuze kuqoqwe amasiginali wokudlidliza ngesikhathi sokusebenza kwamavalvu, kuhlaziya izici zokudlidliza ukuze kutholwe ukuthi i-valve inephutha yini.
5. Indlela yokuxilonga ye-Hydraulic
Hlaziya ukusebenza kwesistimu futhi uhlole imbangela yamaphutha ngokuthola amapharamitha afana nokucindezela nokugeleza ngaphakathi kwevalvu.
4,Isu lokuvikela lokugcinwa kwamavalvu eglobhu kagesi e-flange
1. Ukuhlolwa okuvamile
Hlola njalo ukubukeka kwe-valve yeglobu ye-flange kagesi, bheka ukuguga nokulimala kwendawo yokuvala, ukupakisha, isiqu se-valve nezinye izingxenye, futhi ulungise ngokushesha noma yiziphi izinkinga ezitholakele.
2. Ukugcoba njalo
Gcoba njalo izingxenye ezinjengama-actuator kagesi nezindlela zokudlulisa ukuze uqinisekise ukusebenza kahle kwamavalvu.
3. Ukuhlanza njalo
Hlanza ukungcola nokungcola ngaphakathi nangaphandle kwevalvu ukuze uvimbele ukuminyana kwe-valve, ukuvuza, nokunye ukungasebenzi kahle.
4. Lungiselela ukusebenza
Lungisa ngokunengqondo ukuvuleka kwe-valve nesivinini sokuvala, i-torque namanye amapharamitha ukuze ugweme umthelela omkhulu nokuguga.
5. Izinyathelo zokulwa nokugqwala
Khetha izinto ezifanele zokunqanda ukugqwala ngokusekelwe ezicini ze-medium ukuze uthuthukise ukumelana nokugqwala kwe-valve.
6. Ukuqeqeshwa nokuhlola
Qinisa ukuqeqeshwa nokuhlolwa kwabaqhubi, uthuthukise amakhono okusebenza, futhi unciphise amaphutha abantu.
5,Isiphetho
Ukuxilongwa kwephutha kanye nesu lokuvikela lokuvikela lama-valve eglobhu kagesi e-flange kuwukhiye wokuqinisekisa ukusebenza okuphephile nokuzinzile kwezinhlelo zokulawula uketshezi. Ngokuhlaziya izinhlobo nezimbangela zamaphutha, kuhlanganiswe nezindlela zokuxilonga amaphutha kanye namasu okuvikela okugcina, kuyasiza ukuthuthukisa ukusebenza kanye nempilo yesevisi yama-valve eglobhu e-flange kagesi. Ekusetshenzisweni okungokoqobo, izindlela ezihlukahlukene kufanele zisetshenziswe ngokuguquguqukayo ngokuvumelana nezimo ezithile ukuze kuqinisekiswe ukusebenza okuvamile kwe-valve.
