1. Ukuxhumeka kwe-Flange
Lolu uhlobo oluvame ukusetshenziswa kakhulu lokuxhuma kuma-valve.Ngokusho kokuma kwendawo ehlangene, ingahlukaniswa ngezigaba ezilandelayo:
● Uhlobo olubushelelezi: lusetshenziselwa i-valve enengcindezi ephansi futhi elula ukuyicubungula.
● Uhlobo lwe-concave convex: ingcindezi yokusebenza iphezulu, futhi iwasha eqinile emaphakathi ingasetshenziswa.
● Uhlobo lwe-Tenon groove: iwasha ene-plastic deformation enkulu ingasetshenziswa, esetshenziswa kakhulu endaweni ebolayo futhi enomphumela omuhle wokuvala.
● Uhlobo lwe-Trapezoidal groove: sebenzisa indandatho yensimbi eyi-elliptical njenge-gasket, futhi usebenzise i-valve enengcindezi yokusebenza ≥ 64kg / cm2 noma i-valve yokushisa ephezulu.
● Uhlobo lwelensi: i-gasket umumo welensi, eyenziwe ngensimbi.Ukuze i-valve yomfutho ophezulu noma i-valve yokushisa ephezulu enengcindezi yokusebenza ≥ 100kg / cm2.
● Uhlobo lwe-O-ring: Lolu uhlobo olusha kakhulu lokuxhumana kwe-flange, oluthuthukiswa ngokuvela kwama-O-rings enjoloba ahlukahlukene.Ithembeke kakhulu kune-gasket eyisicaba evamile emphumeleni wokuvala.
2 Ukuxhumana okuwuchungechunge
Lena indlela elula yokuxhuma, evame ukusetshenziselwa ama-valve amancane.Kunezimo ezimbili:
● Ukubekwa uphawu okuqondile: izintambo zangaphakathi nezangaphandle zidlala indima eqondile ekuvaleni uphawu.Ukuqinisekisa ukuthi akukho ukuvuza ekuhlanganyeleni, uwoyela oholayo, intambo yentambo kanye nebhande le-polytetrafluoroethylene lezinto ezingavuthiwe zivame ukusetshenziselwa ukugcwalisa.Phakathi kwabo, ibhande le-polytetrafluoroethylene eluhlaza lisetshenziswa kabanzi.Le nto inokumelana nokugqwala okuhle, umphumela omuhle kakhulu wokuvala, ukusetshenziswa okulula nokulondolozwa.Lapho iqaqa, ingasuswa ngokuphelele, ngoba ifilimu enganamatheli, ephakeme kakhulu kumafutha omthofu nentambo ye-hemp.
● Ukuvala uphawu okungaqondile: amandla okuqiniswa kwentambo adluliselwa ku-gasket phakathi kwezindiza ezimbili ukwenza i-gasket idlale indima yokuvala.
3 Ukuxhumana kwe-Ferrule
Ukuxhumana kwe-ferrule kuthuthukile eminyakeni yamuva nje e-China.Izinzuzo zaleli fomu lokuxhuma zimi kanje:
● Ivolumu encane, isisindo esincane, isakhiwo esilula kanye nokuhlakazeka okulula;
● Amandla okuxhumana aqinile, ububanzi bohlelo lokusebenza, futhi angakwazi ukumelana nokucindezela okuphezulu (1000 kg / cm2), izinga lokushisa eliphezulu (650 ° C) kanye nokudlidliza komthelela;
● Izinhlobonhlobo zezinto zingakhethwa, ezifanele ukulwa nokugqwala;
● Izidingo zokunemba kokucubungula aziphezulu;
● Ilungele ukufakwa endaweni ephakeme.Njengamanje, indlela yokuxhuma i-ferrule isetshenzisiwe kweminye imikhiqizo emincane yamavalvu echweba e-China.
4 Ukuxhumana kwe-clamp
Lena indlela yokuxhumana esheshayo, idinga kuphela ama-bolts amabili, afanele ama-valve anengcindezi ephansi evame ukuhlakazwa.
5 Ukuxhumana kwangaphakathi okuqinile
Ngokuhlukile kwezinye izindlela zokuxhuma, amandla angaphandle asetshenziselwa ukulwa nokucindezela okuphakathi ukuze kuzuzwe uphawu.Indandatho yokuvala ifakwe ku-cone yangaphakathi, yakha izinga elithile ngobuso obuphambene nendawo.Ukucindezela okuphakathi kudluliselwa ku-cone yangaphakathi, bese kuba yindandatho yokuvala.Endaweni eyi-conical ene-angle engaguquki, izakhi ezimbili ziyakhiqizwa, eyodwa ihambisana nomugqa ophakathi womzimba we-valve kanti enye icindezelwa odongeni lwangaphakathi lomzimba we-valve.Ingxenye yokugcina amandla aziqinisayo.Uma umfutho ophakathi umkhulu, amandla aziqinisayo abe mkhulu.Ngakho lolu hlobo lokuxhumana lufanele i-valve yokucindezela okuphezulu.Uma kuqhathaniswa nokuxhumeka kwe-flange, kungasindisa izinto eziningi kanye nabasebenzi, kodwa futhi kudinga amandla athile okuqinisa ngaphambili, ukuze asetshenziswe ngokuthembekile lapho ingcindezi ku-valve ingekho phezulu.
Kunezinhlobo eziningi zokuxhuma kwe-valve, isibonelo, amanye ama-valve amancane angadingi ukususwa ahlanganiswe namapayipi;amanye amavalvu angewona awensimbi asebenzisa ukuxhuma kwesokhethi, njll. Abasebenzisi bevalvu kufanele baphathwe ngokwemibandela ethile.
