Ukwehluleka okuvamile kwama-valve omoya

I-valve yomoya ibhekisela kakhulu kusilinda edlala indima ye-actuator, emoyeni ocindezelwe ukuze yakhe umthombo wamandla wokushayela i-valve, ukuze kufezwe injongo yokulawula iswishi. Lapho ipayipi elilungisiwe lithola isignali yokulawula ekhiqizwa ohlelweni lokulawula oluzenzakalelayo, amapharamitha afanele (njenge: izinga lokushisa, izinga lokugeleza, ingcindezi, njll.) azolungiswa.

I-TWS Valve yethu inganikezaivalvu yebhabhathane ehlezi ngerabha, njengohlobo lwe-wafer, i-lug butterfly valve, i-eccentric butterfly valve,ivalvu yesango, ivalvu yebhola, ivalvu yokuhlola njalo njalo. Umsebenzi uhlanganisa i-actuator yomoya.

Ivalvu yomoya ikakhulukazi inezinzuzo ezilandelayo: okokuqala, ivalvu yomoya ihamba ngokushesha futhi umyalo wokulungisa ungaqedwa ngesikhathi esifushane; okwesibili, ivalvu yomoya ingaba amandla okushayela isilinda esikhulu ukuze kufezwe i-torque enkulu; okwesithathu, ivalvu yomoya ingaba sesimweni sokusebenza esiphephile nesizinzile isikhathi eside ngaphansi kwazo zonke izinhlobo zezimo ezinzima.

Iphutha elivamile lama-valve omoya

1 Ukwanda nokuvuza kokuvuza kwevalvu yomoya

Inani lokuvuza kwevalvu yomoya lincike kakhulu ekushintsheni kwevalvu. Ukwanda kokuvuza kwevalvu yomoya kungenxa yezici ezimbili ezilandelayo: okokuqala, ukuguguleka komnyango wevalvu yomoya; uma ivalvu ixubene nezinto zangaphandle noma i-bushing yangaphakathi ishisiwe, noma ingaphansi kokulawulwa kwengcindezi phakathi kwemidiya, lapho umehluko wengcindezi we-medium mkhulu, ngoba ivalvu ayikwazi ukuvalwa ngokuphelele, futhi ekugcineni ibangele ukuvuza kwevalvu yomoya kwande.

2 Iphutha elingazinzile le-valve yomoya kanye nembangela yalo

Kokubili ukungazinzi kwengcindezi yesignali engazinzile kanye nokucindezela komthombo womoya kungabangela ukuthi i-valve yomoya ingazinzile. Ukucindezela kwesignali engazinzile kuzobangela ukungazinzi kokukhipha okungazinzile komlawuli, futhi lapho ukucindezela komthombo womoya kungazinzile, i-valve yokunciphisa ingcindezi izohluleka ngenxa yomthamo omncane we-compressor. Kungenzeka futhi ukuthi isenzo se-valve yomoya esibangelwa igebe phakathi komunye nomunye singazinzile lapho indawo ye-amplifier spray baffle ingalingani. Ngaphezu kwalokho, ipayipi lokukhipha eliqinile noma umugqa wokukhipha kuzobangela ukungazinzi kwesenzo se-valve yomoya; i-valve yebhola ye-amplifier izothinta nokuzinza kwe-valve yomoya.

3. Ukwehluleka kokudlidliza kwe-valve yomoya kanye nembangela
Ama-valve omoya asengozini yezici zemvelo ezizungezile ngesikhathi somsebenzi. Ngemva kokusebenza isikhathi eside kwe-bushing kanye ne-valve core, ngaphansi kwesenzo sokungqubuzana, lokhu kokubili kuzokwakha imifantu, ukuba khona kokudlidliza okwengeziwe okuzungeze i-valve yomoya, ukungalingani kwesikhundla sokufakwa kwe-valve yomoya kuzoholela ekudlidlizeni kwe-valve yomoya. Ngaphezu kwalokho, lapho usayizi we-valve yomoya ukhethwe ngendlela engafanele noma isiqondiso sokuvala se-valve yesihlalo esisodwa singahambisani nesiqondiso sokugeleza kwe-medium, i-valve yomoya nayo izodlidliza.

4 Isenzo se-valve yomoya sokwehluleka kancane kanye nembangela

Ukubaluleka kwesiqu akungabazeki ngesikhathi sokunyakaza kwevalvu yomoya. Lapho isiqu sevalvu sigobile, ukungqubuzana okubangelwa ukunyakaza kwaso okujikelezayo kuzokwanda, okubangela ukuthi ivalvu yomoya ihambe kancane. Lapho uwoyela wokugcoba we-graphite kanye ne-asbestos filler, ukugcwaliswa kwe-polytetrafluoroethylene kungavamile nakho kuzobangela ukuthi isenzo sevalvu yomoya sihambe kancane, ivalvu yomoya lapho kunothuli ngaphakathi komzimba wevalvu, ivalvu yomoya efakwe ne-position-er, njll., izokwandisa ukumelana nokusebenza kwesiqu sevalvu yomoya, ngaleyo ndlela ibangeleivalvu yebhabhathane elinomoyaisenzo sihamba kancane.
