Incazelo ebanzi nolwazi lwencazelo lwamavalvu esango

1.Incazelo yevalvu yesango Iwuhlobo lwevalvu esetshenziswa kakhulu epayipini. Idlala kakhulu indima yokuxhuma nokusika i-medium. Ayifanelekile ukulawula izinga lokugeleza kwesilinganiso esimaphakathi, kodwa ingahlulela izinga lokugeleza ngokuya ngokukhuphuka nokuwa kwesiqu (isb. ivalvu yesango elinwebekayo lokulwa nomlilo elinesikali sokuvula nokuvala). Uma kuqhathaniswa namanye ama-valve, ama-valve esango anezinhlobonhlobo zesicelo sokucindezela, izinga lokushisa, izinga kanye nezinye izidingo. 2. Isakhiwo seSango Valve Ama-valve esango angahlukaniswa abe uhlobo lwe-wedge, uhlobo lwesango elilodwa, uhlobo lwesango elinwebekayo, uhlobo lwesango eliphindwe kabili kanye nohlobo lwesango elihambisanayo ngokusho kwesakhiwo sawo sangaphakathi. Ngokomehluko we-stem ukwesekwa, ingahlukaniswa ibe i-valve yesango ye-stem evulekile kanye ne-valve yesango elimnyama. 3. Umzimba wevalvu kanye nomgijimi Isakhiwo somzimba we-valve yesango sinquma ukuxhumana phakathi kwe-valve yomzimba kanye nepayipi, umzimba wevalvu kanye nesembozo sevalvu. Mayelana nezindlela zokukhiqiza, kukhona ukuphonswa, ukubumba, ukubumba, ukuphonsa nokushisela, kanye nokushisela ipuleti lamapayipi. Umzimba we-valve wokwakha usuthuthuke waba yizinga elikhulu, kuyilapho umzimba we-valve yokuphonsa usuthuthuke kancane kancane waba yizinga elincane. Noma yiluphi uhlobo lwe-valve yesango lungafojwa noma lufakwe, kuye ngezidingo zomsebenzisi kanye nezindlela zokukhiqiza eziphethwe umkhiqizi. Indlela yokugeleza yomzimba we-valve yesango ingahlukaniswa ngezinhlobo ezimbili: uhlobo olugcwele ububanzi kanye nohlobo lobubanzi obuncishisiwe. Ububanzi bokuziswana bephaseji lokugeleza ngokuyisisekelo bufana nobubanzi obuncane be-valve, futhi ububanzi obuncane bomzila wokugeleza kunobubanzi obuncane bevalvu bubizwa ngokuthi uhlobo lobubanzi obuncishisiwe. Kunezinhlobo ezimbili zomumo wokuncipha: ukuncipha okufanayo kanye nokuncipha okufanayo. Isiteshi esine-tapered siwukuncishiswa kwedayamitha engafaniswanga. Imbobo yokuphela kwe-inlet yalolu hlobo lwe-valve ngokuyisisekelo iyafana ne-diameter yegama, bese iyancipha kancane kancane ibe encane esihlalweni. Izinzuzo zokusebenzisa umgijimi we-shrinkage (kungakhathaliseki ukuthi i-conical tube non-uniform shrinkage noma i-uniform shrinkage) ilingana nosayizi we-valve, enganciphisa usayizi wesango, ukuvula nokuvala amandla kanye nomzuzu. Okubi ukuthi ukumelana nokugeleza kuyanda, ukwehla kwengcindezi nokusetshenziswa kwamandla kuyanda, ngakho-ke imbobo yokuncipha akufanele ibe nkulu kakhulu. Ukuze kuncishiswe i-diameter ye-tapered tube, isilinganiso sobubanzi obungaphakathi besihlalo kuya kububanzi obujwayelekile ngokuvamile singu-0.8-0.95. Amavalvu okwehlisa anobubanzi obuncane obungaphansi kuka-250mm ngokuvamile anesihlalo esingaphakathi esiyidayamitha igiya elilodwa eliphansi kunobubanzi obujwayelekile; Amavalvu okwehlisa anedayamitha encane elingana noma engaphezu kuka-300 mm ngokuvamile anesihlalo esiphakathi nendawo yamagiya amabili aphansi kunobubanzi obujwayelekile. 4. Ukunyakaza kwama-valve esango Lapho i-valve yesango ivala, indawo yokuvala ingavalwa kuphela ngokucindezela okuphakathi, okusho ukuthi, kuphela ngokucindezela okuphakathi ukuze ucindezele indawo yokuvala yesango esihlalweni ngakolunye uhlangothi ukuze qinisekisa indawo yokuvala, okuzivala yona. Ama-valve amaningi esango aphoqeleka ukuba avale, okungukuthi, lapho i-valve ivala, isango kufanele liphoqelelwe esihlalweni ngamandla angaphandle ukuze kuqinisekiswe indawo yokuvala. Imodi yokunyakaza: Isango levalvu yesango lihamba ngendlela eqondile nesiqu, eyaziwa nangokuthi i-valve yesango elivulekile. Ngokuvamile kunemicu ye-trapezoidal ku-rod yokuphakamisa. Ngenati elingaphezulu kwevalvu kanye negroove eqondisayo emzimbeni wevalvu, ukunyakaza okujikelezayo kuguqulwa kube ukunyakaza okulandelanayo, okusho ukuthi, i-torque esebenzayo iguqulwa ibe i-thrust yokusebenza. Lapho uvula i-valve, lapho ukuphakama kwesango lokuphakamisa isango lilingana no-1: 1 izikhathi ububanzi be-valve, umzila wokugeleza uvulekile ngokuphelele, kodwa lapho usebenza, lesi sikhundla asikwazi ukugadwa. Ekusetshenzisweni okungokoqobo, i-vertex ye-valve stem isetshenziswa njengophawu, okungukuthi, indawo ye-valve stem enganyakazi isetshenziswa njengendawo yayo evulekile egcwele. Ukuze ucabangele isenzakalo sokukhiya sokushintsha kwezinga lokushisa, i-valve ivame ukuvulwa endaweni ye-vertex futhi ihlehliselwe ku-1/2-1 ukuphenduka njengendawo ye-valve evuleke ngokugcwele. Ngakho-ke, indawo evulekile egcwele ye-valve inqunywa indawo yesango (okungukuthi unhlangothi). Amanye amantongomane esiqu se-valve yesango abekwe epuleti lesango. Ukuzungezisa isondo lesandla kushayela isiqu ukuthi sizungeze, okuphakamisa ipuleti lesango. Lolu hlobo lwe-valve lubizwa ngokuthi i-rotary stem gate valve noma i-valve yesango elimnyama. 5. Izinzuzo zokusebenza zama-valve wesango 1. Ukumelana noketshezi lwe-valve kuncane, ngoba umzimba we-valve wesango uqondile, ukugeleza okuphakathi akushintshi isiqondiso, ngakho ukumelana nokugeleza kuncane kunamanye ama-valve; 2. Ukusebenza kokuvala kungcono kune-valve yeglobhu, futhi ukuvula nokuvala konga abasebenzi kakhulu kune-valve yeglobhu. 3. Uhlu olubanzi lwezinhlelo zokusebenza, ngaphezu kwesitimu, uwoyela kanye neminye imidiya, kodwa futhi ilungele okuphakathi okuqukethe izinto eziqinile ze-granular kanye ne-viscosity ephezulu, futhi ifanele ukusetshenziswa njenge-valve yokukhipha umoya kanye nama-vacuum system valves; 4. I-valve yesango i-valve ene-double flow direction, enganqunyelwe ukugeleza kwe-medium. Ngakho-ke, i-valve yesango ifanele amapayipi lapho okuphakathi kungashintsha isiqondiso sokugeleza, futhi kulula ukuyifaka. 6. Ukushiyeka kokusebenza kwe-valve yesango 1. Ubukhulu bomklamo ophezulu kanye nesikhathi eside sokuqala nokuvala. Lapho uvula, kuyadingeka ukuphakamisa ipuleti ye-valve engxenyeni engenhla yegumbi le-valve, futhi lapho uvala, kuyadingeka ukulahla wonke amapuleti e-valve esihlalweni se-valve, ngakho-ke ukuvuleka nokuvala i-valve plate kukhulu. futhi isikhathi side. 2. Ngenxa yokungqubuzana phakathi kwezindawo ezimbili zokuvala ze-valve plate kanye nesihlalo se-valve ekuvuleni nasekuvaleni, indawo yokuvala kulula ukuyinwaya, enomthelela ekusebenzeni kokuvala nempilo yesevisi, futhi akulula. ukugcina. 7. Ukuqhathaniswa kokusebenza kwamavalvu esango anezakhiwo ezihlukene 1. Uhlobo lwe-Wedge i-valve yesango elilodwa A. Isakhiwo silula kune-valve yesango elinwebekayo. B. Emazingeni okushisa aphezulu, ukusebenza kokuvala akufani nokunwebeka kwevalvu yesango noma i-valve yesango eliphindwe kabili. C. Ifanele izinga lokushisa eliphezulu okulula ukulipheka. 2. I-valve yesango elinwebekayo A. Kuyindlela ekhethekile yohlobo lwe-wedge i-valve yesango elilodwa. Uma kuqhathaniswa ne-valve yesango le-wedge, ukusebenza kokuvala kungcono ekushiseni okuphezulu, futhi isango akulula ukuminyana ngemva kokushiswa. B. Ifanele isitimu, imikhiqizo kawoyela oshisayo kanye nemidiya kawoyela negesi, kanye nokushintshashintsha izingxenye njalo. C. Ayilungele indlela yokupheka kalula. 3. Amavalvu esango eliphindwe kabili A. Ukusebenza kokuvala kungcono kunevalve yesango le-wedge. Uma i-engeli yokuthambekela yendawo yokuvala nokulingana kwesihlalo kunganembile kakhulu, isenokusebenza okuhle kokuvala. B. Ngemuva kokuthi indawo yokuvala yesango isigugile, i-pad yensimbi engezansi phezulu kwendawo eyindilinga ingashintshwa futhi isetshenziswe ngaphandle kokuvela nokugaya indawo yokuvala. C. Ifanele isitimu, imikhiqizo kawoyela okushisa okuphezulu kanye nemidiya kawoyela negesi, kanye nokushintshashintsha izingxenye njalo. D. Ayilungele indlela yokupheka elula. 4. Amavalvu esango ahambisanayo A. Ukusebenza kokuvala kubi kakhulu kunamanye amavalvu esango. B. Ifanele okuphakathi nendawo enezinga lokushisa eliphansi nokucindezela. C. Ukucutshungulwa nokugcinwa kwendawo yokuvala isango nesihlalo kulula kunezinye izinhlobo zamavalvu esango. 8. Izexwayiso Zokufakwa Kwevalvu Yesango 1. Ngaphambi kokufaka, hlola ikamelo levalvu nendawo yokuvala. Akukho ukungcola noma isihlabathi esivunyelwe ukunamathela. 2. Ama-bolts engxenyeni ngayinye yokuxhuma kufanele aqiniswe ngokulinganayo. 3. Ukuhlola isikhundla sokugcwalisa kudinga ukuhlanganisa, hhayi kuphela ukuqinisekisa ukubekwa uphawu kokugcwalisa, kodwa futhi nokuqinisekisa ukuthi isango livula ngokuguquguqukayo. 4. Ngaphambi kokufaka ama-valve esango ensimbi enziwe ngomgunyathi, abasebenzisi kufanele bahlole uhlobo lwe-valve, usayizi wokuxhuma kanye nesiqondiso sokugeleza kwemidiya ukuze baqinisekise ukuhambisana nezidingo zevalvu. 5. Lapho ufaka ama-valve esango ensimbi enziwe ngomgunyathi, abasebenzisi kufanele bagcine isikhala esidingekayo sokushayela i-valve. 6. Ukufakwa kwezintambo zomshini wokushayela kuzokwenziwa ngokomdwebo wesifunda. 7. Ama-valve esango ensimbi afojiwe kufanele agcinwe njalo. Akukho ukungqubuzana okungahleliwe kanye ne-extrusion evunyelwe ukuthikameza ukuvala.
