Izidingo zezinto ezibonakalayo kanye nezobuChwepheshe ze-valve I-actuator kagesi yevalvu yesiteshi samandla (1)
Okokuqala, mayelana nokukhethwa kwama-valve, ezinsukwini zokuqala zokusungulwa kweNdawo Ekhethekile, inethiwekhi yamapayipi okuhambisa amanzi yayingaphansi kwamakhilomitha ayi-10, futhi iningi loxhaxha lwamapayipi lwalusebenzisa amavalvu esango. Ngenxa yenethiwekhi yepayipi elula kanye nokuqina okuhle kwama-valve esango, indima yama-valve kunethiwekhi yamapayipi yayingabalulekile kakhulu. Ivalve uvemvane uphawu oluthambile. Indawo yokuvala ngokuvamile yenziwe ngerabha ye-butadiene kanye nerabha ye-epDM, njll. Irabha ebuyisiwe ayivunyelwe ngokuphelele. Izinto zokuvala kufanele zihlangabezane nezidingo zezinkomba zezempilo, kanye nokukhombisa ukuhlolwa kokuguga kanye nedatha yokuhlola ukumelana nokugqoka;
Okokuqala, mayelana nokukhethwa kwama-valve, ezinsukwini zokuqala zokusungulwa kweNdawo Ekhethekile, inethiwekhi yamapayipi okuhambisa amanzi yayingaphansi kwamakhilomitha ayi-10, futhi iningi loxhaxha lwamapayipi lwalusebenzisa amavalvu esango. Ngenxa yenethiwekhi yepayipi elula kanye nokuqina okuhle kwama-valve esango, indima yama-valve kunethiwekhi yamapayipi yayingabalulekile kakhulu. Futhi ekuqaleni kwawo-1990, ukusetshenziswa kwe-valve butterfly ezweni lonke ngamandla, ngaleso sikhathi, ukukhiqizwa kwe-valve butterfly yaseShayina kusanda kuqala, emzimbeni amandla okuphonsa awekho phezulu, ukusebenza kokuvalwa kwe-valve plate apron kubi, izinga lezinkinga ze-valve butterfly lingaphezulu. futhi kusobala ngokwengeziwe. Ama-valve asetshenziswa kunethiwekhi yamapayipi ahlukaniswa ngokwezinga: i-valve yesango isetshenziswa uma i-DN≤400mm, i-butterfly valve isetshenziswa uma i-DN400mm. Isisekelo esiyinhloko sokuhlukaniswa ukuthi i-90% yomsebenzi wokuphatha ukulungiswa kunethiwekhi yamapayipi kwenzeka kunethiwekhi yepayipi elincane elingaphansi kwe-DN400mm, ngakho-ke kudinga ukuqina okuhle kokuvula nokuvalwa kwama-valve kunethiwekhi yamapayipi. Futhi ngenxa yokuthi i-caliber incane, amandla okusebenza okuvula nokuvala ama-valve awakhulu. Kodwa-ke, imvamisa yokuqhuma kwamapayipi kunethiwekhi yamapayipi e-DN400mm iphansi kakhulu kunaleyo yenethiwekhi yamapayipi amancane, futhi amandla okusebenza okuvula nokuvala ngemva kokusebenzisa i-valve butterfly ayancipha.
Inkinga yamanje kusixhumanisi sokuthengwa kwe-valve inkampani yethu iphinde ibeke phambili izidingo zobuchwepheshe ezihambisanayo:
1, izidingo zempahla ye-valve
Umzimba we-valve kanye ne-valve plate kufanele yenziwe nge-ductile iron.
(2) isiqu. Amavalvu esango azoba yisiqu sensimbi engagqwali (2Cr13), amavalvu ovemvane azoba yinsimbi engenasici;
Izinto zamantongomane. Kufanele yenziwe ngethusi elicijile le-aluminium noma ithusi le-aluminium ephonsiwe, obunzima bayo namandla amakhulu kunesiqu se-valve;
Impahla yendawo yokuvala uphawu
A, i-valve yesango le-wedge evamile. Indandatho yethusi kufanele ibe yi-aluminium yethusi noma ithusi elibunjiwe le-aluminium;
B, ivalve uvemvane uphawu oluthambile. Indawo yokuvala ngokuvamile yenziwe ngerabha ye-butadiene kanye nerabha ye-epDM, njll. Irabha ebuyisiwe ayivunyelwe ngokuphelele. Izinto zokuvala kufanele zihlangabezane nezidingo zezinkomba zezempilo, kanye nokukhombisa ukuhlolwa kokuguga kanye nedatha yokuhlola ukumelana nokugqoka;
Ukupakishwa kwe-valve shaft. I-V indandatho yerabha noma i-carbon fibre efakwe i-polytetrafluoroethylene ukupakisha, kufanele iqinisekise ukusebenza kahle kokuvala, akukho ukuvuza; Lapho uvula futhi uvala njalo, ukupakisha akusebenzi, akugugi, futhi umphumela wokuvala kufanele ugcinwe isikhathi eside, okufanele kuqinisekiswe okungenani iminyaka eyishumi noma ngaphezulu.
2. Izidingo zobuchwepheshe zebhokisi lokudlulisa isivinini esiguquguqukayo
Impahla yomzimba kufanele ihambisane nempahla yomzimba;
(2) Ibhokisi lokuhambisa liyadingeka ukuthi livalwe futhi likwazi ukumelana nokujula kwamanzi okungengaphansi kwamamitha amathathu ngaphandle kokuvuza;
(3) Awekho ama-sundries ebhokisini, futhi amafutha kufanele asetshenziselwe ukuvikela ingxenye eseduze yegiya.
3, i-soft seal butterfly valve isakhiwo kanye nezidingo zobuchwepheshe:
(1) Ivalvu kufanele ivalwe ngokuzungeza kwewashi;
② Umzimba we-valve kufanele unikezwe i-butterfly plate limit block, amandla awo kufanele abe makhulu kune-torque yokuvula ye-valve;
Indandatho yokuvala kufanele imiswe emzimbeni we-valve, futhi ipuleti lokucindezela indandatho yokuvala kufanele libe yipuleti lokucindezela le-dovetail elinezinyathelo ezinokwethenjelwa zokulwa nokuxegiswa;
(4) indawo yokuvula neyokuvala ivalvu kufanele ibe i-square tenon, kanye nobukhulu bokulinganisa, futhi ibheke phansi;
Ulayini wesikali we-valve yokuvula nedigri yokuvala kufanele uphonswe kukhava yebhokisi legiya noma igobolondo lepuleti lokubonisa ngemva kwesikhombisi-ndlela sokuguqulwa, indawo efanayo, futhi umugqa wesikali ubhulashwe ngempushana ye-fluorescent ukukhombisa ukudonsa amehlo.
4, ukugeleza kwamanzi okuthintana engxenyeni yomzimba we-valve kanye nepuleti ye-valve kufanele kube yizinyathelo zokunqanda ukubola, njengokuhlanza isihlabathi nokugqwala okufutha ngempushana engenabuthi epoxy resin.
5, izidingo zezimpawu zamavalvu
Lapho i-valve iphuma efektri, imboni ye-valve kufanele inikeze ivelufa ngayinye inombolo engaguquki, inombolo yayo kanye nemodeli ye-valve, izinga, umfutho wegama, inombolo ye-valve, umkhiqizi, usuku lokukhiqiza nokunye okuqukethwe kwelebula ye-valve kufanele kumiswe emzimbeni we-valve.

6.6
Ingabe isikhathi esidingwa i-actuator kagesi ukuze sisebenze sisuka lapho "sivaliwe ngokuphelele" siye endaweni "yokukhanya okugcwele" noma sisuka ku-"0%" sifinyelele "100%".
Iphutha langaphakathi
Ngaphansi kwezimo zereferensi ezishiwo, umehluko omkhulu phakathi kwejika lesici se-stroke langempela kanye nejika lesici se-stroke esicacisiwe uboniswa njengephesenti le-stroke elinganiselwe.
3. I-Hysteresis plus Dead band
Umehluko omkhulu phakathi kwamanani e-stroke amabili ahambisanayo esignali efanayo yokufaka ekhuphukayo futhi ewela phakathi kwebanga le-stroke elilinganiselwe, elivezwa njengephesenti le-stroke elinganiselwe.
3.9 Ukugoba okufile
Isikhawu esilinganiselwe lapho ushintsho esiqondisweni sesignali yokokufaka lungabangeli noma yiluphi ushintsho ekushayeni, oluvezwa njengephesenti lobubanzi benani lesignali.
3.10. Ingxenye Yokulawula Amandla
Idivayisi kagesi eguqula futhi ikhulise amasiginali kagesi okufakwayo ukuze ulawule izikhombisi-ndlela zokuqala, ukuma kanye nokuzungezisa kwemoto.
