Nikuba kuti kusala nzila yakuswaanganya aakati ka vvalavu ya butterfly a payipi naakuti zibelesyo zililuzi naa pe kuyoopa kuti vvalavu ya paipi ibeleke, kutontola, kutontola akuzuza. Nzila zyakuswaanganya mavalvu zizibilikide zibikkilizya: kuswaanganya flange, kuswaanganya wafer, kuswaanganya butt welding, kuswaanganya threaded, kuswaanganya ferrule, kuswaanganya clamp, kuswaanganya self-sealing azimwi nzila zyakuswaanganya.
A. Kuswaangana kwa flange
Kuswaangana kwa flange nchintuvvalavu ya butterfly iijisi ntamboaama flange kumamanino oonse obile aamubili wa valve, aayo aayendelana ama flange aali mumupayipi, mpawo abikkwa mumupayipi kwiinda mukubikka ma flange. Kuswaangana kwa flange ninzila ibelesyegwa kapati mumavalvu. Ma flanges alaandaanizyigwa muzibeela zipapalete (RF), zibeela zipapalete (FF), zibeela zipapalete alimwi azibeela zipapalete (MF), azimwi.
B. Kuswaangana kwa Wafer
Ivalvu ilibikkidwe akati kama flange obile, mpawo mubili wa valve wawafer butterfly valvekanjikanji ilaa mpako yakubikkila kutegwa kube kuuba kubikka akubikka.
C. Kuswaangana kwasolder
(1) Kuswaangana kwabutt welding: Magolelo oonse obile aamubili wa valve alachitwa kuba butt welding grooves kweendelana aziyandikana butt welding, eezyo zyeendelana abutt welding grooves yamupayipi, mpawo zilajatikizyigwa aamupayipi kwiinda mukuwelda.
(2) Kuswaangana kwakuwelda kwasoketi: Magolelo oonse obile aamubili wavalvu alachitwa kweendelana aziyandikana mukuwelda kwasoketi, mpawo alaswaanganizyigwa amupayipi kwiinda mukuwelda kwasoketi.
D. Kuswaangana kwa nsinga
Kuswaangana kwatunsingo ninzila nguba yakuswaangana alimwi kanjikanji kubelesyegwa kumavalvu masyoonto. Mubili wavalvu ulabelesegwa kweendelanya azyeelelo zyantambo, mpo kuli misyobo yobile yantambo yamukati ayaanze. Kweendelana amutwe uuli aamupayipi. Kuli misyobo yobile yazijatikizyo:
(1) Kujala chakugaminina: Nsinga zyamukati azyaanze zilabeleka mulimo wakujala. Kuchitila kuti kujatana kutazwi, kanjikanji kulazuzyigwa amafuta aa lead, thread hemp antoomwe a PTFE raw material tape; aakati kazyeezyo PTFE teepu yazibelesyo zibelesyegwa kapati; eechi chintu chilakonzya kukazya kubola mpawo chijala kabotu. Nchuubauba kubelesya akubamba. Notugwisya, ulakonzya kugwisigwa nkaambo nchintu chitalibonyi pe, chili kabotu kwiinda mafuta aa lead antoomwe a thread hemp.
(2) Kujala kutali kwakugaminina: manguzu aakuyumya nsinga alatumwa kuchikwabilizyo aakati kazibeela zyobile, kuchitila kuti chikwabilizyo chibe amulimu wakujala.
E. kuswaangana kwa ferrule
Kuswaangana kwa ferrule kwakachitwa munyika yangu muminyaka misyoonto yainda. Njiisyo yakujatana akujala kwayo njakuti aawo nati niyasinikizyigwa, ferrule ilasinikizyigwa, kuchitila kuti nkomo ya ferrule ilume mubwaanda bwaanze bwa payipi, mpawo busena bwaanze bwa ferrule bulaswaanganizyigwa a joint kakuli kusinikizyigwa. Mukati kamubili uli afwaafwi abusena buteteete, aboobo kuvwundauka kulakonzya kulesyegwa. Mbuli mavalvu aazibelesyo. Bubotu bwanzila eeyi yakuswaangana mbubuti:
(1) Bupati buniini, buteteete, bupange buuba, buuba-uba kugwisya akubunganya;
(2) Nguzu zyakujatana ziyumu, nzila zyiingi zyakubelesya, kukazyigwa kwakusinikizyigwa (1000 kg/cm 2), kupya kupati (650 ° C) akuzungaana akuzungaana;
(3) Zintu zyiingi zilakonzya kusalwa, zyeelede kulwana kubola;
(4) Ziyandikana mukuchita zintu munzila iiluzi tazili atala pe;
(5) Nchintu chibotu kubikka mujulu.
Kwalino, nzila yakuswaangana ya ferrule yakazuminwa muzintu zimwi zya valve zya diameter nsyoonto muchisi changu.
F. Kuswaangana kwamagolelo
Eeyi ninzila yakufwambaana kuswaangana, iyandika buyo mabbawulu obile, mpawovvalavu yamamanino iijisi migotiileelela kubelesya muya muniinimavwili aabutterflyeezyo kanjikanji zigwisigwa. mbuli mavalvu aakusanzya.
G. Kuswaangana kwamukati kulikwabilila
Zyoonse nzila zyakuswaanganya zili atala aawa zibelesya manguzu aanze kuchitila kuti zikonzye kujala. Eezi zitobela zipandulula nzila yakuliyumya yakulijata kubelesya nguzu zili akati-akati.
Inkomo yayo yakujala ilabikkwa mukati ka kkoni mpawo ilapanga kkona limwi mpawo lubazu lulangide aakati. Kusinikizyigwa kwachintu chili akati-akati kulatumwa kuchikobela chamukati mpawo kuya kuchikwabilizyo. Aatala aachikoni chakkona limwi, manguzu obile alapangwa, yomwe aMuzila waakati kamubili wavalvu ulikozyenye anze, mpawo aimwi ilasinikizyigwa abwaanda bwamukati bwamubili wavalvu. Nguzu zyakumamanino ninguzu zyakuliyumya. Ikuti naa nguzu zyaakati-kati kazikomena, nkokuti nguzu zyakuliyumya zilakomena. Aboobo, nzila eeyi yakuswaanganya ileelela kumavalvu aajisi nguzu kapati.
Kweezyanisya akuswaanganya flange, chikwabilila zintu zyiingi anguzu zyabantu, asi alimwi chiyanda kuti kube kubikkwa kwakusaanguna, kuchitila kuti chibelesyegwe oobotu aawo muya muvalvu nuutali mupati. Mavalvu akapangwa kubelesya nzila yakulijatilila alikke kanjikanji ngamavalvu aajisi muya mupati.
Kuli nzila zyiingi zyakuswaanganya mavalvu, mbuli chitondeezyo, mavalvu amwi masyoonto aatayandiki kugwisigwa alaswaanganizyigwa amapaipi; amwi mavalvu aatakwe nsimbi alaswaanganizyigwa amasoketi azimwi. Babelesyi ba Valve beelede kulanganizigwa kweendelana abukkale buliwo.
Kagwalo:
(1) Nzila zyoonse zyakuswaanganya zyeelede kulanga zyeelelo zyeendelana akusalazya zyeelelo kutegwa ivalvu yasalwa itabikkidwe.
(2) Kanjikanji, mupaipi mupati a valve zilaswaanganizyigwa a flange, mpawo payipi nsyoonto a valve zilaswaanganizyigwa a ntambo.
