Umkhiqizi wevalvu ye-Butterfly ene-Flanged Triple Offset yensimbi ephonswe nge ...
Mayelana ne-GB Standards
Izindinganiso ze-GB (i-Guobiao Standards) ziyizindinganiso zikazwelonke ezikhishwa yiShayina zemikhiqizo yezimboni. Kuma-valve e-butterfly, izindinganiso ze-GB ezifanele zivame ukumboza:
Izidingo zokuklama nokukhiqiza
Ubukhulu bobuso nobuso
Izilinganiso zokushisa kwengcindezi
Ubukhulu be-Flange
Izinqubo zokuhlola nokuhlola
Izindinganiso ezifanayo ezihlobene zingafaka:
I-GB/T 12238 (amavalvu evemvane)
I-GB/T 9113 (ubukhulu be-flange)
I-GB/T 12224 (izidingo ezijwayelekile zamavalvu ensimbi)
Ukuthobela imithetho kuqinisekisa ukushintshana, ukuphepha, kanye nokusebenza okulinganayo ngaphakathi kwezinhlelo zamapayipi ezisekelwe ku-GB.
Iyini i-Triple Offset Butterfly Valve?
Ivalvu ye-butterfly e-offset kathathu ihlukile kumiklamo evamile ye-concentric noma ye-double offset ngenxa ye-offset ezintathu ezihlukile ku-geometry yayo. Lezi zi-offset ziqeda ukungqubuzana phakathi kwediski nesihlalo ngesikhathi sokusebenza, zihlinzeka ngokuvalwa okuhlala ku-torque, kusuka kunsimbi kuya kunsimbi.
2.1 I-Offset Yokuqala
Ishafti ibekwe ngemuva kwesihlalo ukuze kuncishiswe ukuthintana kwesihlalo ngesikhathi sokuvulwa.
2.2 I-Offset Yesibili
I-shaft isuselwe emgqeni ophakathi wepayipi, okuvumela idiski ukuthi ijikele isuke esihlalweni ngokushesha nje lapho ivuleka.
2.3 I-Offset Yesithathu
Indawo yokuvala iklanyelwe njengephrofayili eyindilinga kunokuba ibe yisihlalo esiyisiyingi esilula. Lokhu kudala isenzo esifana nekhamera esiqinisekisa ukuvala nokuvula isihlalo okungenazingxabano.
Umphumela uba yivalvu engahlikihliki, ehlala e-torque ekwazi ukufeza ukusebenza okuqondile, okungavuzi lutho.
Ukwakhiwa Nezinto Ezisetshenziswayo
3.1 Umzimba Wevalvu
Umzimba uvame ukukhiqizwa ngezinto zensimbi ezibunjiwe ezifana nalezi:
I-WCB (insimbi yekhabhoni)
I-WC6 noma i-WC9 (insimbi ye-alloy)
I-CF8 noma i-CF8M (insimbi engagqwali)
Ukwakhiwa kwensimbi ephonswe kunikeza:
Amandla aphezulu okusebenza ngomshini
Ukumelana nokucindezela okuphezulu
Ukufaneleka kwamazinga okushisa aphezulu
Ukuqina kwesakhiwo
Iziphetho ezigobile zihambisana nezindinganiso ze-GB flange ukuze kube lula ukufaka emapayipini ezimboni.
3.2 Idiski
Idiski yenziwe ngokunemba ukuze igcine i-triple offset geometry enembile. Ivame ukwenziwa ngensimbi engagqwali noma insimbi ye-alloy ukuze kuthuthukiswe ukugqwala nokumelana nokuguguleka.
3.3 Uhlelo Lokuvala
Uhlelo lokuvala luvame ukuba nalokhu:
Indandatho yophawu enensimbi elaminethiwe
Isihlalo sensimbi engagqwali
Izinto eziqinile ezifana neStellite
Lokhu kuvalwa kwensimbi kuya kwensimbi kuvumela ivalvu ukuthi isebenze ezimweni zokushisa okuphezulu kanye nezingcindezi eziphezulu.
3.4 Isiqu nama-Bearings
Isiqu senzelwe ukudlulisa i-torque kahle ngenkathi kunciphisa ukuphambuka. Ama-bearings anciphisa ukungqubuzana futhi athuthukise ukushelela kokusebenza.
Isimiso Sokusebenza
Ivalvu ye-butterfly ephindwe kathathu isebenza ngokujikeleza kwekota:
Uma ivalvu iqala ukuvuleka, idiski iyaphakama isuke esihlalweni ngaphandle kokungqubuzana.
Njengoba ijikeleza ama-degree angu-90, ihambisana nokugeleza, okuvumela ukudlula okugcwele.
Ngesikhathi sokuvala, idiski ithinta isihlalo kuphela esigabeni sokugcina.
I-torque esetshenziswa lapho kuvalwa idala ukuvala okuqinile.
Ngokungafani namavalvu ebhabhathane ahlala ethambile, ukuvala kufezwa nge-torque yomshini kunokuba kube nokuguquguquka okunwebekayo.
Izici Eziyinhloko
5.1 Ukusebenza Okungavuzi Kakhulu
I-geometry ye-triple offset inikeza ukuvala okuqinile okuhlangabezana nezindinganiso zokuvuza eziphezulu, okuhlanganisa nezidingo zokuhlola ze-API 598 noma ze-GB.
5.2 Amandla Okushisa Okuphezulu
Amavalvu amathathu abekwe ngensimbi angasebenza emazingeni okushisa angaphezu kuka-400°C, kuye ngezinto zokwakha.
5.3 Ukuvalwa Kwezinhlangothi Zombili
Ivalvu inikeza ukuvala okuthembekile kuzo zombili izinkomba zokugeleza, okulungele ukuhlelwa kwamapayipi ayinkimbinkimbi.
5.4 Ukusebenza Okuphansi Kwe-Torque
Ngenxa yomklamo ongenayo ukungqubuzana, i-torque yokusebenza incishiswe kakhulu uma kuqhathaniswa nama-valve endabuko ahlala ngensimbi.
5.5 Impilo Ende Yenkonzo
Ukuguguleka okuncane kwesihlalo kwandisa isikhathi sokusebenza futhi kunciphisa imvamisa yokugcinwa.
Izilinganiso Zokucindezela
Amavalvu e-butterfly ajwayelekile e-GB atholakala ngezigaba ezahlukene zokucindezela, njenge-PN10, PN16, PN25, PN40, PN64, PN100. Isilinganiso sokucindezela sincike ezintweni zomzimba kanye nemininingwane yomklamo.

Impilo Yesevisi Kude Okumaphakathi
Izinga Lokuvuza Cishe u-zero Iphansi kodwa incike esihlalweni
Ilungele Isevisi Ebucayi Yebo Kunqunyelwe
Uma kuqhathaniswa nama-valve esango, ama-valve e-butterfly e-triple offset alula, acinene kakhulu, futhi adinga isikhala esincane sokufakwa.
Izinto Okufanele Uzicabangele Zokufaka
Ukuqinisekisa ukusebenza kahle kakhulu:
Qinisekisa ukuhambisana kwe-flange nezindinganiso ze-GB.
Qinisekisa ukuthi i-adhesion ilungile ngesikhathi sokufakwa.
Qinisa amabhawodi ngokulinganayo ukuze ugweme ukuphambuka.
Gwema ukushisa okukhulu kokushisela eduze kwevalvu.
Qinisekisa izilungiselelo ze-actuator uma zenzeka ngokuzenzakalelayo.
Ukufakwa kahle kuvimbela ukungahleleki kahle kwesihlalo nokuvuza.
Iziqondiso Zokunakekela
Nakuba yakhelwe ukuqina, ukuhlolwa njalo kuyanconywa:
Hlola izindawo zokuvala ukuthi azigugi yini.
Hlola ukupakisha kwesiqu ukuze kutholakale ukuthi akuvuzi yini.
Qinisekisa ukulinganiswa kwe-actuator.
Qinisekisa ukusebenza kahle.
Amavalvu ahlala ngensimbi adinga ukulungiswa okuncane uma kuqhathaniswa nezinhlobo ezihlala zithambile.
