Vavu yosindikizira mphete yazinthu zodziwika bwino komanso momwe zinthu zimagwirira ntchito Vavu yachipata chamagetsi

Zida za mphete zosindikizira ma valve zimakhala ndi magulu awiri achitsulo ndi osakhala achitsulo. Zipangizo wamba ndi mikhalidwe yake ntchito ndi motere:
1. Labala yopangira
Rabara yopangidwa ndi yabwino kuposa mphira wachilengedwe pakukana kwamafuta, kukana kutentha komanso kukana dzimbiri. General kupanga mphira kutentha t ≤ 150 ℃, mphira zachilengedwe t ≤ 60 ℃, mphira ntchito mwadzina kuthamanga PN ≤ 1MPa globe valavu, valavu pachipata, valavu diaphragm, valavu butterfly, valavu cheke, valavu achepetsa ndi mavavu ena chisindikizo.
2, nayiloni
Nayiloni ili ndi mawonekedwe otsika kwambiri komanso kukana kwa dzimbiri. Nayiloni imagwiritsidwa ntchito makamaka kutentha t ≤ 90 ℃, kuthamanga mwadzina PN ≤ 32MPa valavu ya mpira, valavu yapadziko lonse.
3. Teflon
Ptfe imagwiritsidwa ntchito kwambiri pamavavu a globe, mavavu a pachipata ndi mavavu a mpira ndi kutentha T ≤ 232 ℃ ndi kuthamanga mwadzina PN ≤ 6.4MPa.
4, chitsulo chachitsulo
Chitsulo chotayira chimagwiritsidwa ntchito pa mavavu a pachipata, ma valve a globe ndi ma plug ma valve a gasi ndi mafuta, ndi kutentha kwa T ≤ 100 ℃ ndi kuthamanga mwadzina PN ≤ 1.6mpa.
5. Babbitt aloyi
Babbitt aloyi ntchito mavavu ammonia amasiya kutentha T-70 ~ 150 ℃ ndi kuthamanga mwadzina PN ≤ 2.5MPa.
6. Aloyi yamkuwa
Zida zodziwika bwino za aloyi yamkuwa ndi 6-6-3 tin bronze ndi 58-2-2 mkuwa wa manganese. Copper aloyi kuvala kukana, oyenera kutentha T ≤ 200 ℃, kuthamanga mwadzina PN ≤ 1.6MPa madzi ndi nthunzi, nthawi zambiri ntchito mavavu pachipata, mavavu globe, valavu cheke, mavavu pulagi, etc.
7, chrome chitsulo chosapanga dzimbiri
Zitsulo zosapanga dzimbiri za Chrome zomwe zimagwiritsidwa ntchito kwambiri ndi 2Cr13, 3Cr13 pambuyo pozimitsa ndi kutentha, kukana kwa dzimbiri. Nthawi zambiri amagwiritsidwa ntchito kutentha t ≤ 450 ℃, kuthamanga mwadzina PN ≤ 32MPa madzi, nthunzi ndi mafuta ndi mavavu ena atolankhani.
8, chromium nickel titaniyamu chitsulo chosapanga dzimbiri
Mtundu womwe umagwiritsidwa ntchito kwambiri wa chromium nickel chitsulo chosapanga dzimbiri ndi 1Cr18Ni9ti, yomwe ili ndi kukana kwa dzimbiri, kukana kukokoloka komanso kukana kutentha. Oyenera kutentha T ≤ 600 ℃, kuthamanga mwadzina PN ≤ 6.4MPa nthunzi, asidi nitric ndi TV zina, ntchito valavu globe, valavu mpira, etc.
9, nitriding chitsulo
Chitsulo chodziwika bwino cha nitriding chitsulo ndi 38CrMoAlA, chomwe chimakhala ndi kukana kwa dzimbiri komanso kukana abrasion pambuyo pobisalira. Nthawi zambiri amagwiritsidwa ntchito popanga mavavu pachipata chamagetsi ndi kutentha T ≤ 540 ℃ ndi kuthamanga mwadzina PN ≤ 10MPa.
10, kukhumudwa
Boronizing ndi thupi kapena chimbale thupi zinthu mwachindunji kukonzedwa kusindikiza pamwamba, boronizing pamwamba mankhwala, kusindikiza pamwamba kuvala kukana ndi kwabwino kwambiri. Amagwiritsidwa ntchito pochiza valavu yamagetsi.
Vavu yachipata cha gasi Pamanja tembenuzani gudumu ndi dzanja kuti tsinde likwere ndi kugwa, kuti muthamangitse mbale ya pachipata kuti mutsegule ndi kutseka valavu. Valovu ILI NDI "KUTSEGUKA" NDI "KUTENGA" KUSONYEZA ZINTHU, ZINTHU ZOTSATIRA ZOCHITIKA, CHIPATIKO CHOGWA, CHONONGA CHONONGA PAMALO "KUTSATIRA", ndipo VALVU YAtsekedwa. Tembenukirani COUNTERCLOCKWISE, CHITENGO AMAUKA, NINGAZO imaloza PAMALO “PA”, NDIPO VAVU AKUTSEKUKA. Poyesa kukakamiza kwa payipi, ndikofunikira kugwiritsa ntchito ndodo yotalikirapo. Tsekani valavu ndipo iyenera kutseka pamalo ake (onani malo a pointer). Tembenuzani gudumu lamanja mozungulira kuti mutseke, ndipo mutembenuzire mopingasa kuti mutsegule.
Mtundu wa 1.
Mavavu opangidwa ndi manja opangidwa ndi gasi omwe ali ndi m'mimba mwake DN100mm ~ 300mm ndi kuthamanga mwadzina PN0.8mpa kugwirizana kwapang'onopang'ono akuphatikizidwa mu ndondomekoyi.
2. Gwiritsani ntchito
2.1 Vavu iyi imagwiritsidwa ntchito ngati chida chotsegulira ndi kutseka pamapaipi a gasi ndi gasi wachilengedwe.
2.2 Sankhani zinthu za valve malinga ndi sing'anga.
2.2.1 Valavu yachitsulo ndi yoyenera gasi, gasi wachilengedwe ndi media zina.
2.3 Kutentha koyenera:
2.3.1 Kutentha koyenera kwa valavu yachitsulo ya ductile ndi ≤120 ℃
Kapangidwe ka 3.
3.1 Mapangidwe oyambira a valve yachipata cha gasi akuwonetsedwa mu Chithunzi 1
3.2 Gasket yovala ziwalo imadzazidwa ndi bolodi la asbestosi la rabara ndi mphira wa fluorine kuti atsimikizire kusindikizidwa kodalirika.
4. Kuchita
MAVAVU A Pamanja AMAtembenuzira CHANJA NDI DZANJA KUTI AWEZE NDI KUCHEKETSA tsinde, motero AKUYENZA CHITSEMO Mmwamba NDI pansi KUTI ABUKULU NDI KUtseka VALVU. Valve ili ndi "KUTSEGUKA" NDI "KUTENGA" KUSONYEZA NTCHITO, ZINTHU ZOTSATIRA ZOCHITIKA, CHITEKO CHOGWA, CHONONGA CHONONGA PAMODZI PA "KUTSATIRA", ndipo valve WOtsekedwa. Tembenukirani COUNTERCLOCKWISE, CHITENGO AMAUKA, NINGAZO imaloza PAMALO “PA”, NDIPO VAVU AKUTSEKUKA.
5. Kusungirako, kukonza, kukhazikitsa ndi kugwiritsa ntchito
5.1 Vavu iyenera kusungidwa m'chipinda chowuma ndi mpweya wabwino, ndipo mapeto onse a valve ndi otsekedwa.
5.2 Mavavu osungidwa kwa nthawi yayitali ayenera kuyang'aniridwa nthawi zonse ngati ali ndi dothi. Chisamaliro chapadera chiyenera kuperekedwa pakuyeretsa kwa malo osindikizira kuti ateteze kuwonongeka kwa malo osindikizira.
5.3 Musanayambe kukhazikitsa, fufuzani mosamala ngati chizindikiro cha valve chikugwirizana ndi zofunikira zogwiritsira ntchito.
5.4 Musanayambe kukhazikitsa, chipinda chamkati ndi malo osindikizira a valve ayenera kufufuzidwa. Ngati pali zonyansa, ziyenera kutsukidwa ndi nsalu yoyeretsera.
5.5 mapaipi ayenera kutsukidwa isanayambe kapena itatha kukhazikitsa kuti zitsimikizire kuti palibe zotsalira mu mapaipi.
5.6 Poyesa kuthamanga kwa payipi, ndodo yotambasula yamanja iyenera kugwiritsidwa ntchito. Tsekani valavu ndipo iyenera kutseka pamalo ake (onani malo a pointer). Tembenuzani gudumu lamanja mozungulira kuti mutseke, ndipo mutembenuzire mopingasa kuti mutsegule.
5.7 Vavu iyenera kuwombedwa pafupipafupi kuti isatseke.
5.8 Valavu iyenera kupakidwa mafuta pafupipafupi (masiku 10 ~ 15) kuti ipangitse mafuta osindikizira ndi tsinde la valve ndi zina zosuntha kuti muchepetse torque yosinthira ndikuteteza kusindikiza.
6. Zolakwa zomwe zingatheke, zomwe zimayambitsa, ndi njira zothetsera mavuto zalembedwa mu tebulo
Table 1 Zolakwika zomwe zingatheke, zomwe zimayambitsa, ndi njira zothetsera mavuto 1
Chitsimikizo cha 7.
Wopanga ali ndi udindo wotsimikizira za valve mkati mwa chaka chimodzi atagwiritsidwa ntchito, koma osapitirira miyezi 18 atabereka. Pa nthawi chitsimikizo, chifukwa mankhwala zifukwa khalidwe akhoza anakonza kapena m'malo.
8. Kuyitanitsa malangizo
Chonde nenani poyitanitsa
Kupanikizika mwadzina MPa
M'mimba mwake mwadzina mm
Muyezo wa kutalika kwa kamangidwe
Flange kugwirizana kukula muyezo
Ndi chipangizo chosapaka mafuta
Chipangizo cham'manja ndi makulidwe okhala ndi kapena opanda ndodo yowonjezera
