Noma ngabe kukhetsa indlela yekuhlanganisa emkhatsini we valve ye butterfly kanye neliphayiphi noma imishini kulungile noma cha kutawutsintsa ngalokucondzile ematfuba ekugijima, kucondzisa, kucondzisa kanye nekuvuta kwe valve yeliphayiphi. Tindlela tekuhlanganisa tevalve letivamile tifaka ekhatsi: kuxhumana kwe flange, kuxhumana kwe wafer, kuxhumana kwe butt welding, kuxhumana kwe threaded, kuxhumana kwe ferrule, kuxhumana kwe clamp, kuxhumana kwekutivala kanye naletinye tinhlobo tekuhlanganiswa.
A. Kuxhumana kwe-flange
Kuxhumana kweflange nguivalvu levivane leneflangngema flanges kuto totimbili tincenye temtimba we valve, letihambisana nema flanges lasephayiphini, futsi afakwa ephayiphini ngekutsi kuboshwe ema flanges. Flange uxhumano yifomu uxhumano esetjentiswa kakhulu emavalvu. Ema-flanges ahlukaniswe abe yindzawo levulekile (RF), indzawo lesicaba (FF), indzawo levulekile kanye nendzawo levulekile (MF), njll.
B. Kuxhumana kwe-wafer
Le valve ifakwe emkhatsini wema-flanges lamabili, futsi umtimba wevalve we-Ivalvu yeluvivanekuvame kuba nembobo yekubeka kwentela kufaka kanye nekubeka.
C. Kuxhumana kwesolder
(1) Kuhlanganiswa kwekushisela ngesibumbu: Totimbili tiphetfo temtimba wevalve ticutshungulwa tibe tikhala tekushisela ngesibumbu ngekuya kwetidzingo tekushisela ngesibumbu, letihambisana nemigodzi yekushisela yephayiphi, futsi ticiniswa kuleliphayiphi ngekushisela.
(2) Kuxhumana kwekushisela kwesokhethi: Totimbili tiphetfo temtimba wevalve ticutshungulwa ngekuya kwetidzingo tekushisela kwesokhethi, futsi tihlanganiswa nephayiphi ngekushisela kwesokhethi.
D. Kuxhumana lokunetintsambo
Kuhlanganiswa lokunetintsambo kuyindlela lelula yekuhlanganiswa futsi kuvame kusetjentiselwa emavalvu lamancane. Umtimba wevalve ucutshungulwa ngekuya kwelizinga lentambo ngayinye, futsi kunetinhlobo letimbili tentambo lengekhatsi kanye nentambo yangaphandle. Ihambisana nentambo lesepayipini. Kukhona tinhlobo letimbili tekuxhumana lokunetintsambo:
(1) Kuvala ngalokucondzile: Imicu lengekhatsi nalengaphandle idlala indzima yekuvala ngalokucondzile. Kute kucinisekiswe kutsi lokuhlangana akuvuti, kuvame kugcwaliswa nge oyili leholako, i-hemp yentambo kanye ne-PTFE leluhlata letheyiphu; emkhatsini walo PTFE impahla eluhlata tape isetjentiswa kakhulu; lendzaba inekumelana lokuhle nekugcola kanye nemphumela lomuhle kakhulu wekuvala. Kulula kuyisebentisa nekuyigcina. Uma kuhlukaniswa, ingasuswa ngalokuphelele ngoba iyifilimu lengamatsi, lencono kakhulu kune oyili ye lead kanye ne thread hemp.
(2) Kuvala lokungacondzi: emandla ekucinisa intfo adluliselwa ku-gasket emkhatsini waletindiza letimbili, kute kutsi le-gasket idlale indzima yekuvala.
E. kuxhumana kwe ferrule
Kuxhumana kwe-ferrule kutfutfukiswe kuphela eveni lami eminyakeni yamuva. Umtsetfo wayo wekuhlangana kanye nekuvala kutsi uma le nati iciniswa, le ferrule icindzetelwa, kwentela kutsi umphetfo we ferrule ulume lubondza lwangaphandle lweliphayiphi, bese lendzawo lengaphandle ye cone ye ferrule ixhumene nekuhlangana ngaphansi kwekucindzeteleka. Ngekhatsi kwemtimba kusondzelana nendzawo lecijile, ngako-ke kuvuza kungavinjelwa ngekwetsembeka. Njengemavalvu etintfo tekusebenta. Tinzuzo talendlela yekuxhumana nguleti:
(1) Usayizi lomncane, sisindvo lesilula, sakhiwo lesilula, kulula disassembly kanye umhlangano;
(2) Emandla ekuxhumana lacinile, kusetjentiswa lokubanzi, kumelana nekucindzeteleka lokusetulu (1000 kg/cm 2 ), kushisa lokusetulu (650 ° C) kanye nekushaywa kanye nekudvudvuta;
(3) Tintfo letehlukahlukene tingakhetfwa, letifanele kulwa nekugcola;
(4) Tidzingo tekunemba kwemishini atikho ngetulu;
(5) Kulungele kufakwa endzaweni lephakeme.
Kwanyalo, ifomu lekuxhumana kwe-ferrule selamukelwe kuleminye imikhicito ye-valve lencane-diameter eveni lami.
F. Kuxhumana lokunemigodzi
Lena yindlela yekuxhumana lesheshako, idzinga emabhawudi lamabili kuphela, futsiivalvu yeluvivane lesekugcineni lenemigodziilungele umfutfo lophansiemavalvu evivaneletivame kukhishwa. njengemavalvu ekuhlanteka.
G. Kuxhumana lokucinisako kwangekhatsi
Onkhe lamafomu langetulu ekuhlanganisa asebentisa emandla langaphandle kucedza kucindzeteleka kwemkhatsi kwentela kufeza kuvalwa. Lokulandzelako kuchaza ifomu lokuxhumana self-tightening kusetjentiswa umfutho phakathi.
Indandatho yayo yekuvala ifakwa ku cone lengekhatsi bese yakha i-angle letsite neluhlangotsi lolubheke emkhatsini. Kucindzeteleka kwemkhatsi kudluliselwa ku cone lengekhatsi bese kuya endandathoni yekuvala. Ebusweni be-cone be-angle letsite, kukhicitwa emandla lamabili etincenye, munye une Umugca losemkhatsini wemtimba we-valve uhambisana nengaphandle, bese lomunye ucindezelwa eludongeni lwangekhatsi lwemtimba we-valve. Emandla ekugcina nguwo emandla laticinisako. Lapho kucindzeteleka lokusemkhatsini kukhulu, emandla ekuticinisa ayakhula. Ngakho-ke, leli fomu uxhumano lilungele emavalvu umfutfo ophezulu.
Nawucatsanisa nekuhlanganiswa kwe-flange, konga tintfo letinyenti kanye nemandla ebantfu, kepha kuphindze kudzingeke preload letsite, kute isetjentiswe ngekwetsembeka lapho umfutfo ku-valve ungaphezulu. Emavalvu lentiwe kusetjentiswa simiso sekuticinisa kuvala kuvame kuba ngemavalvu lanemfutfo lomkhulu.
Kukhona tinhlobo letiningi tekuhlanganiswa kwemavalvu, sibonelo, lamanye emavalvu lamancane langadzingi kususwa ashiselwa ngemaphayiphi; lamanye emavalvu langasiwo ensimbi ahlanganiswa ngemasokhethi njalonjalo. Basebentisi bevalve kufanele baphatfwe ngekuya kwesimo lesitsite.
Phawula:
(1) Tonkhe tindlela tekuhlanganisa kumele tibhekisele emazingeni lahambisanako futsi ticacise emazinga kute kuvikelwe kutsi i-valve lekhetsiwe ingafakwa.
(2) Ngalokuvamile, liphayiphi lelikhulu kanye nevalve kuhlanganiswa nge-flange, bese liphayiphi lelincane kanye nevalve kuhlanganiswa ngentsambo.
