UD Series imikhono ethambileyo ehleli ivelufa butterfly
UD Series umkhono othambileyo ohleli ivelufa yebhabhathane yipatheni yeWafer eneflange, ubuso ngobuso yi-EN558-1 20 uthotho njengohlobo lwe-wafer.
Iimpawu:
I-1.Izimbobo zokulungisa zenziwe kwi-flange ngokwemigangatho, ukulungiswa lula ngexesha lofakelo.
I-2.Ibholithi yokuphuma okanye ibholithi yecala elinye esetyenzisiweyo. Ukutshintshwa okulula kunye nokugcinwa.
3.Isitulo somkhono othambileyo sinokwahlula umzimba kumajelo eendaba.
Umyalelo wokusebenza kwemveliso
1. Imigangatho yeflange yombhobho kufuneka ihambelane nemigangatho yevalvu yebhabhathane; cebisa ukusebenzisa i-welding neck flange, i-flange ekhethekileyo yeevalve zebhabhathane okanye i-flange yombhobho odibeneyo; Musa ukusebenzisa i-slip-on welding flange, umthengisi kufuneka avume phambi kokuba umsebenzisi asebenzise i-slip-on welding flange.
2. Ukusetyenziswa kweemeko zokufakelwa kwangaphambili kufuneka kuhlolwe ukuba ngaba ukusetyenziswa kweevalve zebhabhathane kunye nokusebenza okufanayo.
3. Ngaphambi kokuba umsebenzisi wofakelo acoce umphezulu wokutywina wevalvu, qiniseka ukuba akukho mdaka uncanyathiselweyo; ngaxeshanye ucoce umbhobho we-welding slag kunye nezinye i-debris.
4.Xa ufaka, i-disc kufuneka ibe kwindawo evaliweyo ukuqinisekisa ukuba i-disc ayingqubani ne-flange yombhobho.
5. Zombini iziphelo zezitulo zevalve zisebenza njengetywina le-flange, isitywina esongezelelweyo asikho mfuneko xa ufaka ivalve yebhabhathane.
6. Ivalve yebhabhathane inokufakwa kuyo nayiphi na indawo (ethe nkqo, ethe tyaba okanye ethambekileyo). Ivalve yebhabhathane enesayizi enkulu inokufuna isibiyeli.
7. Ukungqubana xa uhambisa okanye ugcina ivalve yebhabhathane kusenokubangela ukuba ivalve yebhabhathane inciphise ukutywinwa kwayo. Kuphephe idiski yevalve yebhabhathane ukusuka ekungqubekeni ukuya kwizinto eziqinileyo kwaye kufuneka ivuleke kwi-4 ° ukuya kwi-5 ° indawo ye-engile ukuze kugcinwe umphezulu wokutywina ungonakalisi ngeli xesha.
8. Qinisekisa ukuchaneka kwe-flange welding phambi kokufakwa, ukuwelda emva kokufakwa kwevalve yebhabhathane kunokubangela umonakalo kwirabha kunye nokugcinwa kokugquma.
9. Xa usebenzisa i-valve ye-butterfly esebenza nge-pneumatic, umthombo womoya kufuneka ugcine owomileyo kwaye ucocekile ukuze ugweme imizimba yangaphandle ekungeneni kumqhubi we-pneumatic kwaye ichaphazele ukusebenza komsebenzi.
10. Ngaphandle kweemfuno ezizodwa eziqatshelweyo ekuthengeni ivalve yebhabhathane inokufakwa kuphela ngokuthe nkqo kunye nokusetyenziswa kwangaphakathi kuphela.
11. Imeko yokuphazamiseka, izizathu kufuneka zichongwe, zilungiswe, zingankqonkqozi, zibethe, zibhaso okanye zandise umqhubi wesixhobo ngengalo yokunyanzela ukuvula okanye ukuvala ivalve yebhabhathane ngenkani.
12. Ngethuba lokugcinwa kunye nexesha elingasetyenziswanga, i-valve ye-butterfly kufuneka igcinwe yomile, ikhuselwe emthunzini kwaye igweme izinto ezinobungozi ezijikeleze ukuguguleka.
