Ithini indlela yokuhlola ingcindezi yevalvu yesango?

Isango liyinqama ye-headstock, futhi isiqondiso sokunyakaza kwe-valve disc sibhekene nesiqondiso soketshezi, futhi i-valve ingavuleka ngokugcwele futhi ivalwe ngokugcwele, ayikwazi ukulungiswa kanye ne-throttle. I-valve yesango ivalwe ngesihlalo se-valve kanye ne-disc ye-valve, ngokuvamile indawo yokuvala izokweqa izinto zensimbi ukuze kwandiswe ukumelana nokugqoka, njengokuvela kwe-1Cr13, STL6, insimbi engagqwali nokunye.I-disc ine-disc eqinile kanye ne-elastic disc. Ngokusho komehluko we-disc, ama-valve esango ahlukaniswe ama-valve esango aqinile kanye nama-valve esango elinwebekayo.

indlela yokuhlola ingcindezi ye-valve yesango

Okokuqala, i-disc ivuliwe, ukuze ukucindezela ngaphakathi kwe-valve kukhuphuke kunani elicacisiwe. Khona-ke, vala inqama, susa ngokushesha i-valve yesango, uhlole ukuthi kukhona ukuvuza ezinhlangothini ezimbili ze-disc, noma faka ngokuqondile indawo yokuhlola ngenani elicacisiwe kupulaki yekhava ye-valve, futhi uhlole uphawu ezinhlangothini zombili ze-disc. Indlela engenhla ibizwa ngokuthi ingcindezi yokuhlola ephakathi. Le ndlela ayifanele ukuhlolwa kophawu lwe-valve yesango ngaphansi kobubanzi obujwayelekile be-DN32mm.

Enye indlela ukuvula i-disc ukwenza ukucindezela kokuhlolwa kwe-valve kukhuphuke kunani elishiwo; bese uvala i-disc, vula ipuleti eliyimpumputhe ekugcineni, bese uhlola ukuvuza kobuso bophawu. Bese uhlehla, phinda ukuhlolwa kuze kube yilapho ufaneleka njengenhla.

Ukuhlolwa kokuvala ekugcwaliseni kanye ne-gasket ye-valve ye-pneumatic kufanele kwenziwe ngaphambi kokuhlolwa kokutywinwa kwe-disc.

Umgomo wokusebenza we-actuator kagesi
I-actuator kagesi iyinhlanganisela ye-actuator ne-valve yokulawula ohlelweni lokulawula oluzenzakalelayo. Indima yayo ohlelweni lokulawula oluzenzakalelayo ukwamukela isignali evela kumlawuli, futhi ngesikhundla sayo nezici ekuqhutshweni kwamapayipi, ukulawula ukuhamba kwenqubo yemidiya yokulawula inqubo yokukhiqiza ngaphakathi kwebanga elidingekayo.
Indlela yokugcina nokugcina i-valve?
Ukuze kube nokusebenza okujwayelekile okuqhubekayo kwesikhathi eside, kuyadingeka ukuba nokugcinwa njalo nokuphathwa okuqinile kwazo zonke izinto zokusebenza nemishini.Ama-valve e-Jinbin axhunywe nalawa madivayisi namadivayisi
Ukuze udlale ukusebenza kwayo kokulawula kwezingxenye ezibalulekile, ngakho-ke,Ama-valve e-Jinbinkufanele kubhekwe njengenkinga yesondlo nokuphatha okuphelele.
Amavalvu e-Jinbin ayizingxenye ezibalulekile ezixhuma la madivayisi namadivayisi ndawonye futhi adlale ukusebenza kwawo kokulawula, ngakho-ke kufanele acabangele zonke izinkinga zokunakekela nokuphatha.
 
Ukugcinwa kwe-i-valveesitokisini
Ukuthuthwa kwe-valve endaweni yokugcina impahla, umnakekeli kufanele abe ngesikhathi sezinqubo zokugcina, ezihambisana nokuhlolwa nokugcinwa kwe-valve. Umgcini kufanele ahlole ngokucophelela imininingwane yemodeli yevalvu, ahlole ukubukeka kwekhwalithi yevalvu, futhi asize abahloli bevalvu ngaphambi kokuhlolwa kwamandla okugcina kanye nokuhlolwa kokuvala. Hlangana nenqubo yokwamukela i-valve, ingaphathwa ngezinqubo zokugcina; ukwehluleka kufanele futhi kugcinwe ngendlela efanele, ukuze kusingathwe iminyango efanele.
Emtatsheni wezincwadi we-valve, ukusula ngokucophelela, ukuhlanza i-valve ohlelweni lokuthutha lwamanzi nothuli olungcolile, kulula ukugqwala phezulu, isiqu, indawo yokuvala uphawu kufanele ifakwe ungqimba lwe-agent elwa nokugqwala noma unamathisele ungqimba lwephepha le-anti- Rust ukuze livikelwe; i-valve yokungena kanye neziteshi zokuphuma ukuze kusetshenziswe ikhava yepulasitiki noma iphepha le-wax ukuze livalwe, ukuze lingangeni ukungcola.
I-Inventory kufanele yenziwe ngokuhambisana nobukhulu nobukhulu be-oda, ukukhishwa emashalofini; ama-valve amakhulu angakhishwa endaweni yokugcina impahla phansi, ngokusho kwencazelo yemodeli Abekwe izingcezu. I-valve kufanele ibekwe iqonde, hhayi indawo evalekayo ye-flange nephansi, kodwa ingavunyelwe ukuthi inqwabelane.
Ukuze ugcine i-valve isesimweni esihle, ngaphezu kwesidingo sendawo yokugcina impahla eyomile nengena umoya, ihlanzekile futhi ihlanzekile, kufanele kube nesethi yesistimu yokuphatha ethuthukisiwe, yesayensi yazo zonke ukugcinwa kwe-valve kufanele igcinwe njalo ihlolwe.
Ukuze kusetshenziswe isikhathi eside i-valve, uma kusetshenziswa ukupakisha kwe-asbestos, kufanele kube ukupakisha kwe-asbestos kusuka encwadini yokupakisha esusiwe, ukuze kugwenywe ukugqwala kwamakhemikhali kagesi, ukulimala kwesiqu.
Ngaphezu kwezinhlinzeko zokusetshenziswa kwe-rust inhibitors, ama-lubricant, kufanele ashintshwe njalo noma angezwe.
Uyini umgomo wokusebenza we-butterfly valve?

Ukusebenza kufana nalokho kwe-ai-valve yebhola, okuvumela ukuvala ngokushesha. Ama-valve e-Butterflyngokuvamile zithandwa ngoba zibiza kancane kunomunye umklamo wamavalvu, futhi zinesisindo esilula ngakho zidinga ukwesekwa okuncane. I-disc ibekwe phakathi nendawo yepayipi. Induku idlula kudiski iye ku-actuator engaphandle kwevalvu. Ukuzungezisa i-actuator kuguqula idiski ihambisane noma i-perpendicular ekugelezeni. Ngokungafani ne-valve yebhola, i-disc ihlale ikhona ngaphakathi kokugeleza, ngakho-ke ibangela ukwehla kwengcindezi, ngisho nalapho ivuliwe.

Ivalve uvemvane ivela emndenini wamavalvu abizwa ngokuthi ama-quarter-turn valves. Lapho isebenza, i-valve ivuleka ngokugcwele noma ivaliwe lapho i-disc izungeziswa ngokujika kwekota. "Uvemvane" yidiski yensimbi ebekwe phezu kwenduku. Lapho i-valve ivaliwe, i-disc ivuliwe ukuze ivimbe ngokuphelele umgwaqo. Uma i-valve ivuleke ngokugcwele, i-disc ijikeleziswa ikota ukuze ivumele ukudlula okungavinjelwe koketshezi. I-valve ingase ivuleke kancane kancane ukuze i-throttle flow.

Kunezinhlobo ezahlukene zamavalvu ovemvane, ngalinye lilungiselwe izingcindezi ezihlukene kanye nokusetshenziswa okuhlukile. I-valve uvemvane oyiziro-offset, esebenzisa ukuguquguquka kwenjoloba, inezinga lokucindezela eliphansi kakhulu. I-valve ye-butterfly ye-double offset esebenza kahle kakhulu, esetshenziswa ezinhlelweni zokucindezela okuphezulu kancane, isuswa emgqeni ophakathi nendawo yesihlalo sediski kanye ne-body seal (i-offset one), kanye nomugqa ophakathi we-bore (offset two). Lokhu kudala isenzo se-cam ngesikhathi sokusebenza sokuphakamisa isihlalo ngaphandle kwesigxivizo okuholela ekungqubuzaneni okuncane kunalokho okudalwe kumklamo we-zero offset futhi kunciphisa ukuthambekela kwaso kokugqoka. I-valve efaneleka kakhulu kumasistimu okucindezela okuphezulu ivalve yevemvane ephindwe kathathu. Kule valvu i-axis yokuxhumana yesihlalo sediski iyasuswa, esebenza ukuqeda ukuxhumana okuslayidayo phakathi kwediski nesihlalo. Endabeni yama-valve amathathu e-offset isihlalo senziwe ngensimbi ukuze sikwazi umshini njengokuthola ukuvala okuqinile kwebhamuza lapho uthintana nediski.

Kungani I-Valve Yami Ivuza?

Ama-valve angavuza ngenxa yezizathu ezahlukahlukene, okuhlanganisa:

  • I-valve iakuvaliwe ngokugcwele(isb, ngenxa yokungcola, udoti, noma okunye ukuphazamiseka).
  • I-valve iezilimele. Ukulimala kwesihlalo noma uphawu kungabangela ukuvuza.
  • I-valve iakuklanyelwe ukuvala u-100%. Amavaluvu aklanyelwe ukulawula okunembile ngesikhathi sokuphusha angase angabi namandla amahle kakhulu okuvula/okuvala.
  • I-valve yiyonausayizi ongalungileokwephrojekthi.
Yiluphi ulwazi engiludingayo ukuze ngilinganise kahle futhi ngikhethe i-valve?
Izingcezu eziyisithupha zolwazi eziyisisekelo ziyadingeka ukuze usayizi futhi ukhethe ivalvu yokuphepha noma yokusiza ukucindezela:

  1. Usayizi wokuxhuma kanye nohlobo
  2. Setha ingcindezi (psig)
  3. Izinga lokushisa
  4. Ukucindezela emuva
  5. Isevisi
  6. Umthamo odingekayo
