Ukuthi ukukhethwa kwendlela yokuxhumeka phakathi kwe-valve yalevemvane nepayipi noma imishini kulungile noma cha kuzothinta ngqo amathuba okugijima, ukudonsa, ukudonsa nokuvuza kwe-valve yepayipi. Izindlela ezijwayelekile zokuxhumeka ze-valve zifaka phakathi: Ukuxhumeka kwe-Flange, ukuxhumana kwe-welding, ukuxhumana kwe-welding, ukuxhumana okunomunyu, ukuxhumeka kwe-clamp, ukuxhumana okuzenzakalelayo kanye nezinye izindlela zokuxhuma kanye nezinye izindlela zokuxhumana.
A. Ukuxhumeka Flange
Ukuxhumana kwe-Flange kuyintoi-flanged butterfly valveNge-Flanges emaphethelweni emibili yomzimba we-valve, ehambelana nama-flanges epayipini, futhi afakwe kwipayipi ngokushaya ama-flanges. Ukuxhumeka kwe-Flange kuyindlela yokuxhumana esetshenziswa kakhulu kuma-valve. Ama-Flanges ahlukaniswe nge-convex surface (RF), indawo eyisicaba (i-FF), i-convex kanye ne-concave ingaphezulu (MF), njll.
B. WAFEF Uxhumano
I-valve ifakwe maphakathi nama-flanges amabili, kanye nomzimba we-valve wewafer valve butterflyImvamisa inomgodi wokubeka ukwenza lula ukufaka nokubeka.
C. Ukuxhumeka komthengisi
(1) Ukuxhumeka kwe-welding ye-butt
.
D. Ukuxhumana okuhlanganisiwe
Ukuxhumeka okufakiwe kuyindlela yokuxhumana elula futhi kuvame ukusetshenziselwa ama-valve amancane. Isidumbu se-valve sicutshungulwa ngokuya ngeveli ngayinye yentambo, futhi kunezinhlobo ezimbili zentambo yangaphakathi nentambo yangaphandle. Ihambelana nentambo ngepayipi. Kunezinhlobo ezimbili zokuxhumana okuhlanganisiwe:
(1) Ukubekwa uphawu ngqo: imicu yangaphakathi nangaphandle idlala ngokuqondile indima yokubopha uphawu. Ukuze uqinisekise ukuthi ukuxhumana akuvuzi, kuvame ukugcwala ngamafutha okuhola, i-hemp hemp kanye ne-PTFE eluhlaza ebonakalayo; Phakathi kwalo phakathi kwe-PTFE eluhlaza ebonakalayo kusetshenziswa kabanzi; Lokhu okuqukethwe kunokumelana kahle nokugqwayiza kanye nomphumela omuhle kakhulu wokufaka uphawu. Kulula ukuyisebenzisa nokugcina. Lapho kuhlukaniswa, kungasuswa ngokuphelele ngoba kuyifilimu okungeyona enamathelayo, okungcono kakhulu kunamafutha okuhola kanye nentambo ye-hemp.
(2) Ukubekwa uphawu okungaqondile: Amandla okuqina kwentambo adluliselwa ku-gasket phakathi kwezindiza ezimbili, ukuze i-gasket idlala indima yokubopha uphawu.
E. Ukuxhumeka kwe-Ferrule
Ukuxhumeka kwe-ferrule kusungulwe kuphela ezweni lami eminyakeni yamuva. Ukuxhumeka kwayo kanye nesilinganiso sokubopha ukuthi lapho i-nati iqiniswa, i-ferrule ibhekelwe ingcindezi, ukuze umphetho we-ferrule ulume ungene odongeni lwangaphandle lwepayipi, futhi indawo yangaphandle ye-fore ye-ferrule ixhumeke ekuhlanganiseni ngaphansi kwengcindezi. Ingaphakathi lomzimba likuthintana kakhulu ne-tapered ebusweni, ngakho-ke ukuvuza kungavinjelwa ngokuthembekile. Njengezindwangu eziyithuluzi. Izinzuzo zale ndlela yokuxhumanisa yilezi:
(1) usayizi omncane, isisindo esikhanyayo, isakhiwo esilula, ukungafani okulula, okuhlukile kokuxakile kanye noMkhandlu;
(2) amandla okuxhuma okuqinile, ububanzi bokusebenzisa, ukumelana nomfutho ophakeme (1000 kg / cm 2), izinga lokushisa eliphakeme (650 ° C) nokushaqeka nokudlidliza;
(3) Izinto ezahlukahlukene zezinto zokwakha zingakhethwa, zilungele ukulimala;
(4) Izidingo zokunemba kwemishini aziphakeme;
(5) Kulula ukufakwa okuphezulu.
Njengamanje, ifomu lokuxhumeka le-ferrule liye lamukelwa emikhiqizweni ethile ye-valve encane yedwala.
F. Uxhumano oluhlohliwe
Le ndlela yokuxhuma esheshayo, idinga kuphela ama-bolts amabili, futhii-groud end butterfly valveilungele ingcindezi ephansiama-butterfly valveslokho kuvame ukungahlatshwanga. njengama-valves ahlanzekile.
G. Ukuxhuma okuzenzakalelayo kwangaphakathi
Onke amafomu okuxhuma angenhla asebenzisa amandla angaphandle ukususa ingcindezi ye-medium ukuze uzuze ukubekwa uphawu. Lokhu okulandelayo kuchaza ifomu lokuxhuma okuqinisa ngokuqiniseka kusetshenziswa ingcindezi ephakathi.
Indandatho yayo yokuvala uphawu ifakiwe kwisigaxa sangaphakathi futhi yakha i-angle ethile ebheke eceleni okuphakathi nendawo. Ingcindezi ye-Medium idluliselwa kwisigaxa sangaphakathi bese iya kwindandatho yokubopha uphawu. E-Cone ebusweni le-angle ethile, kukhiqizwa amabutho amabili, eyodwa ngomugqa wesikhungo somzimba we-valve ehambisana ngaphandle, kanti enye icindezelwa odongeni lwangaphakathi lomzimba we-valve. Amandla okugcina amandla okuzenzisa. Lapho kukhulu kakhulu ingcindezi ephakathi, kwalapho kukhula khona amandla okuzenzisa. Ngakho-ke, leli fomu lokuxhumeka lilungele ama-valves aphezulu wokucindezela.
Uma kuqhathaniswa noxhumano lwe-flange, lusindisa izinto eziningi ezibonakalayo kanye namandla, kepha futhi kudinga ukulayisha okuthile, ukuze kusetshenziswe ngokuthembekile lapho ingcindezi e-valve ayiphezulu. Ama-valves enziwe ukusebenzisa umgomo wokufaka uphawu kokuzenzisa ngokuvamile ama-valves aphezulu wokucindezela.
Kunezindlela eziningi zokuxhumana ze-valve, ngokwesibonelo, amanye ama-valve amancanyana angadingi ukususwa afakwe ngamapayipi; Amanye ama-valves angewona ama-metallic axhunyiwe ngamasokisi nokunye. Abasebenzisi be-valve kufanele baphathwe ngokwesimo esithile.
Qaphela:
(1) Zonke izindlela zokuxhumana kumele zibhekisele kumazinga ahambisanayo futhi zicacise amazinga ukuvikela i-valve ekhethiwe ukuthi ifakwe.
