Njenge-valve enomsebenzi obalulekile wokuvikela,i-valve yokuphephaisetshenziswa kabanzi emikhunjini yokucindezela ehlukahlukene kanye nezinhlelo zamapayipi, ezingavulwa ngokuzenzakalelayo lapho uhlelo lufinyelela umkhawulo ophezulu wenani elibekiwe lokucindezela Khipha i-medium ngokweqile ngaphandle kwesistimu, futhi ngemuva kokukhishwa kungavalwa ngokuzenzakalelayo ukuze kuqinisekiswe ukuthi umkhumbi we-pressure ungaba ophephile, ingcindezi ethembekile evunyelwe ukusebenza ngaphakathi kobubanzi ukugwema izingozi ezinkulu zokuphepha.

Njengomkhiqizi wamavalvu okuphepha, i-COVNA izimisele ukukusiza ukuthi ukhethe futhi wenze ivalvu yokuphepha oyidingayo.Xhumana nathi ukuze uthole isisombululo se-valve samahhala ngentengo engcono kakhulu.

● Ibanga Losayizi: DN20 kuya ku-DN400

● Ubukhulu.Ingcindezi: 60 bar.Uma udinga ingcindezi ephakeme, sicela usithinte.

● Izinga lokushisa: -29 ukuya ku-425℃

● Izinketho Zezinto ezibonakalayo: CF8, CF8M noma ithusi

● Ukuxhuma: Okuphekiwe noma okufakwe imicu

● Izisetshenziswa ezifanele: I-Steam, umoya, nokunye.

Ukusebenza okuvamile kwe-valve yokuphepha akuhlobene kuphela nokusetshenziswa okuphephile okujwayelekile kwemikhumbi yokucindezela njengama-boilers kodwa futhi kuhlobene ngokuqondile nokuphepha kwezimpilo zabantu kanye nezakhiwo.Ngakho-ke, ukunakwa okukhulu kufanele kukhokhwe ekuhlulekeni okuvamile kwe-Boiler Safety Valve Futhi ukuyiqeda ngesikhathi esifanele.

1. Ivalvu Yokuphepha Iyavuza

Ukuvuza kwe-valve kungenye yezinkinga ezivame kakhulu ze-valve yokuphepha ye-boiler.Ngokuyinhloko ibhekisela ekuvuzeni phakathi kwe-valve disc kanye nesihlalo se-valve ngaphansi kwengcindezi evamile yokusebenza.

Izimbangela zokwehluleka kanye nezixazululo zabo:

1.1Ukungcola kuwela endaweni yokuvala.Sebenzisa isikrufu esiphakamisayo ukuvula ivalvu izikhathi eziningana ukuze ukhiphe ukungcola.

1.2Vala umonakalo ongaphezulu.Ngokwezinga lomonakalo, indlela yokugaya noma yokugaya ngemva kokuphenduka kufanele isetshenziselwe ukulungisa.Ngemuva kokulungiswa kufanele uqinisekise ubushelelezi bokubeka uphawu, ubushelelezi bayo akufanele bube ngaphansi kuka-10.

1.3Ngenxa yokuhlanganiswa okungalungile noma umthwalo wepayipi, ukugxila kwezingxenye kuyabhujiswa.Imithwalo eyengeziwe yamapayipi izohlanganiswa kabusha noma ikhishwe.

1.4Ukucindezela kokuvula kwe-valve kusondele kakhulu ekucindezelweni okuvamile kwemishini, ukuze indawo yokuvala uphawu iphansi kunokucindezela.Uma i-valve ingaphansi kokudlidliza noma ukushintshashintsha kwengcindezi emaphakathi, ijwayele ukuvuza.Ukucindezela kokuvula kufanele kulungiswe ngokuvumelana nesimo samandla semishini.

1.5I-Lose Spring Yehlisa ingcindezi yokubeka futhi ibangele ukuvuza kwe-valve.Kungenzeka kube ngenxa yokushisa okuphezulu noma ukugqwala nezinye izizathu, kufanele kuthathwe ukushintsha intwasahlobo, noma ngisho nokushintsha i-valve nezinye izinyathelo.Uma kubangelwa ukulawulwa okungalungile, isikulufu sokulungisa singaqiniswa kahle.

2. Ingcindezi Ephansi Yokubuyisela Ye-Safety Valve

Imbangela 1:Ingcindezi Ephansi Yokubuyisela izodala inombolo enkulu ye-medium ukuba iphume ngokuhamba kwesikhathi, okuholela ekulahlekeni kwamandla okungadingekile.Isizathu siwukuthi i-valve yokusiza ukushaya kwe-spring enanini elikhulu lokukhipha umusi, leli fomu le-valve yokusiza umfutho ukuze livuleke, okuphakathi kuyaqhubeka nokuphuma, umzimba we-valve yokusiza ukudlidliza, noma i-valve yokukhulula umfutho ngaphambi nangemva kwamandla ngenxa yamandla amakhulu. ukukhishwa okuphakathi kwe-valve yokusiza akwanele ukuqhubeka nokwanda, ngakho-ke umusi kushubhu lokushaya kwenhliziyo eduze kwesihloko segesi yesigubhu siyaqhubeka nokugeleza isenzo sevalvu yokukhulula.

Ngakolunye uhlangothi ngenxa yalolu hlobo lwe-valve yokuphepha ye-impulse impulse safety valve sealing surface.Ekuhleleni kabusha kwayo ukwakha indawo yokucindezela kwe-kinetic, i-spool izophakanyiswa, ukuze i-valve yokuphepha kwe-impulse iqhubeke nokuphuma, ukukhishwa okukhulu kwe-steam, indima ye-spool ekuphepheni kwe-thrust enkulu, ukuphepha komfutho. i-valve kuzoba lula ukubuyela esihlalweni.

Isixazululo 1:Kuleli qophelo, indlela yokuqeda iphutha ukuvala i-valve ye-throttle encane, ukuze ukugeleza kwe-medium ngaphandle kwe-valve yokukhulula umfutho ukunciphisa ukucindezela endaweni yokucindezela kwamandla kinetic, ukuze i-valve yokusiza umfutho ibuyele emuva isihlalo.

Isizathu 2:Isici sesibili esibangela ukucindezela okuphansi kokubuyisela ukuthi imvume efanelekile phakathi kwe-spool kanye nomkhono womhlahlandlela awufaneleki, futhi imvume efanelekile yisikhathi esincane sokubuya ukubambezeleka.

Isixazululo 2:Indlela yokuqeda lokhu kwehluleka ukuhlola ngokucophelela usayizi we-spool futhi uqondise izingxenye zemikhono, negebe lincane kakhulu, ukunciphisa ikhava ye-disc ngokuqondile noma i-disc stop valve cap ububanzi noma ukwandisa i-disc kanye ne-sleeve sleeve gap radial, ukwandisa indawo yomjikelezo wengxenye, ukuze ukugeleza kwesitimu kungaphambukisi lapho ukucindezela kwendawo ukuze kwakhiwe indawo yokucindezela okukhulu kwe-kinetic.

3. Ukuvuza Kwamalungu Omzimba

Ukuvuza kwendawo ehlangene ye-valve yomzimba ikakhulukazi ibhekisela endaweni engaphezulu nephansi ye-valve yokuvuza kwendawo yokuhlangana.

Izimbangela zokwehluleka kanye nezixazululo zabo:

Imbangela 1:Eyodwa indawo ehlangene ye-bolt tight force ayanele noma ibambene ngokwengxenye, okuholela endaweni ehlangene yophawu olungeluhle.
Isixazululo 1:Indlela yokuqeda iwukuba ulungise amandla okuqinisa ibhawodi, kubhawodi eliqinile kufanele libanjwe ngokuhambisana ne-diagonal tightening way, kungcono ukukala yonke i-side side clearance, i-bolt tight ukuze inganyakazi kuze kube manje, futhi wenze. ukukhishwa okuhlangene kwendawo yonke okuhambisanayo.

Isizathu 2:Okwesibili, i-valve body joint surface ye-tooth seal gasket ayihlangabezani nendinganiso.Lokhu kubangela ukuthi ilunga lomzimba we-valve livuze.
Isixazululo 2:Ekunakekeleni ikhwalithi yezingxenye ezisele, ukusetshenziswa kwe-gasket evamile emise okwezinyo kungagwema lesi simo.

Isizathu 3:Okokugcina, indiza ehlangene ye-valve impofu kakhulu noma ngenxa yokwehluleka kophawu lomcamelo wokungcola okunzima.
Isixazululo 3:Ukuqedwa kokuvuza kwendawo yomzimba ngenxa yokungafiki kahle kwendawo yomzimba ukuqaqa i-valve bese ugaya kabusha indawo ehlangene ize ifinyelele izindinganiso zekhwalithi.Uma uphawu luhluleka ngenxa yokupakishwa kokungcola, hlanza ngokucophelela indawo ehlangene ukuze ugweme ukungcola okuwela emhlanganweni we-valve.

4. Ivalvu Yokusiza Ibambezelekile Ukubuya

Ukusebenza okuyinhloko kwe-valve yokukhulula umfutho ngemva kokubuya kwevalvu enkulu ebambezelekile isikhathi sokubuya inkulu kakhulu.

Izimbangela zokwehluleka kanye nezixazululo zabo:

Imbangela 1:Ngakolunye uhlangothi, ukuvuza kwegumbi le-piston levalvu yokusiza enkulu kukhulu.
Isixazululo 1:Indlela yokuqeda lolu hlobo lwenkinga ngokuyinhloko ixazululwa ngokuvula i-valve ye-throttle banzi nokwandisa ububanzi bembobo ye-throttle.

Isizathu 2:Ngakolunye uhlangothi, ukungqubuzana phakathi kwezingxenye ezihambayo kanye nezingxenye zokulungisa ze-valve yokuphepha eyinhloko kuzobangela ukuthi i-valve yokuphepha eyinhloko ibuyele esihlalweni kancane kancane.
Isixazululo 2:Isixazululo sale nkinga ukulingana nezingxenye ezihambayo zevalvu yokusiza kanye nezingxenye ezingashintshi phakathi kwebanga elijwayelekile lekhonsoli yokususa.

5. I-Relief Valve Chatter

Isimo sokudlidliza se-valve yokuphepha ngesikhathi sokuphuma sibizwa ngokuthi i-chatter ye-valve yokuphepha.Isimo sokuxoxa sibangela kalula ukukhathala kwensimbi, okunciphisa ukusebenza kwemishini kwe-Safety Valve futhi kubangele inkinga ebucayi efihliwe yamathuluzi.

Izimbangela zokwehluleka kanye nezixazululo zabo:

Imbangela 1:Ngakolunye uhlangothi, i-valve isetshenziswa ngendlela engafanele, umthamo wokukhipha we-valve mkhulu kakhulu.
Isixazululo 1:Indlela yokuqeda yukuthi ukukhishwa okulinganiselwe kwe-valve kufanele kusetshenziswe eduze ngangokunokwenzeka ekukhishweni okudingekayo kwemishini.

Isizathu 2:Ngakolunye uhlangothi, ngenxa yokuthi ububanzi bepayipi lokungena lincane kakhulu, lincane kunobubanzi bokungena kwe-valve, noma ukumelana kwepayipi lokungena kukhulu kakhulu.
Isixazululo 2:Indlela yokuqeda lapho i-valve ifakiwe, ububanzi bangaphakathi bepayipi yokungena akufanele bube ngaphansi kobubanzi bokungena kwe-valve noma ukumelana kwepayipi lokungena kufanele kuncishiswe Lokhu kungaxazululwa ngokunciphisa ukumelana nokukhishwa. umugqa.

Noma yisiphi isidingo noma inkinga ye-valve yokuphepha, sicela usithinte futhi sizokujabulela ukukusiza ukuyixazulula.
