Kuyika ma valve pampu ndi kugwiritsa ntchito mfundo zazikulu
Pampu ya Chemical imagwiritsidwa ntchito pafupipafupi kwa opanga mankhwala popereka madzi, komanso ndizofala kugwiritsa ntchito mavavu apaipi. Pali mitundu yambiri ndi mawonekedwe a mavavu. Kodi tiyenera kulabadira chiyani mu unsembe ndi ntchito ndondomeko ndi mmene kukhazikitsa?
Chimodzi, choyamba ndi chitsogozo ndi malo, ma valve ambiri ali ndi malangizo: monga globe valve, valve throttle valve, valve kuchepetsa kuthamanga, valve valve, etc. ), kapena osagwira ntchito (monga valavu yochepetsera kuthamanga), komanso ngakhale kuyambitsa ngozi (monga valavu yowunika). Mavavu ambiri amakhala ndi zizindikiro pathupi. Ngati sichoncho, chiyenera kudziwika bwino molingana ndi mfundo yogwira ntchito ya valve. Chipinda cha valve cha valavu ya globe sichiri chofanana, madzimadzi ayenera kumasulidwa kuchokera pansi mpaka pamwamba kudzera pa doko la valve, kuti kukana kwamadzimadzi kumakhala kochepa (kutsimikiziridwa ndi mawonekedwe), kutsegula kwa mphamvu yopulumutsa (chifukwa kupanikizika kwapakatikati), sing'anga yotsekedwa sikukakamiza kulongedza, kukonza kosavuta, ndichifukwa chake valavu yapadziko lonse lapansi siyingatembenuzidwe. Ma valve ena amakhalanso ndi makhalidwe awo.
Osatembenuza chipata (ie dzanja gudumu pansi), apo ayi sing'anga adzakhala mu valavu chivundikiro danga kwa nthawi yaitali, zosavuta dzimbiri tsinde, ndi zina ndondomeko zofunika contraindo. Ndizovuta kwambiri kusintha kulongedza panthawi yomweyo. Tsegulani valavu yachipata, musayike mobisa, apo ayi chifukwa cha dzimbiri lonyowa poyera. Kwezani valavu cheke, unsembe kuonetsetsa kuti chimbale ofukula, kuti kusintha kukweza. Swing cheke mavavu, pamene anaika kuonetsetsa kuti pini mlingo, kuti kusintha kugwedezeka. Valavu yothandizira kupanikizika iyenera kuyikidwa molunjika pa chitoliro chopingasa, ndipo osapendekera mbali iliyonse.
Awiri, valavu unsembe udindo ayenera kukhala yabwino ntchito; Ngakhale kukhazikitsa kuli kovuta kwakanthawi, ganizirani za ntchito yayitali. Chovala cham'manja cha valve chikugwirizana ndi chifuwa (nthawi zambiri mamita 1.2 kutali ndi malo opangira opaleshoni), kuti zikhale zosavuta kutsegula ndi kutseka valve. Vavu yolowera m'manja iyenera kukhala yokwera, osapendekeka, kuti mupewe kugwira ntchito movutikira. Makina a khoma amadalira valavu ya zipangizo, komanso kusiya malo kuti woyendetsa ayime. Kupewa ntchito thambo, makamaka asidi ndi maziko, poizoni TV, apo ayi si otetezeka.

Zitatu, masitepe oyika ma valve: musakhudze valavu yopangidwa ndi zida zophulika.
1, musanayike, yang'anani mosamala ngati mawonekedwe ndi mawonekedwe a ma valve onse akugwirizana wina ndi mzake, ngati kulongedza sikuli bwino, ngati bolt ya gland ili ndi gawo lokwanira lokonzekera, ndipo fufuzani ngati tsinde ndi chimbale zikuyankhula, ngati pali chokhazikika komanso chopindika.
2. Pokweza valavu, chingwecho sichiyenera kumangirizidwa ku dzanja lamanja kapena tsinde la valavu kuti zisawonongeke zigawozi, koma ziyenera kumangirizidwa ku flange; Kwa mavavu olumikizidwa ku payipi, onetsetsani kuti mwayeretsa.
3. Mukayika valavu yotsekera, kusindikiza kusindikiza (mafuta a twine ndi aluminiyamu kapena lamba wa polytetrafluoroethylene yaiwisi yaiwisi) ayenera kukulungidwa pa ulusi wa chitoliro, kuti asalowe mu valavu, kuti asalowe mu valavu, kuti asamalowe mu valavu, zomwe zimakhudza kutuluka kwa media. . Mukayika ma valve a flange, samalani kuti muzimitsa ma bolts molingana komanso mofanana. Vavu flange ndi chitoliro flange ayenera kufanana, wololera chilolezo, kuti kupewa kupsyinjika kwambiri ndi ngakhale kusweka kwa valavu. Makamaka kwa zida zowonongeka ndi ma valve okhala ndi mphamvu zochepa. Mavavu kuti welded ndi mipope ayenera malo-welded poyamba, ndiye kwathunthu kutsegula kutseka mbali, ndiyeno welded akufa.
4, ma valve ena, kuwonjezera pa zofunikira zotetezera, komanso ali ndi bypass ndi chida. Njira yodutsa idayikidwa. Zosavuta kukonza msampha. Ma valve ena, alinso ndi kukhazikitsa bypass. Kaya kukhazikitsa bypass kumadalira momwe ma valve alili, kufunikira ndi zofunikira zopanga.

Zinayi, valavu yosungiramo katundu, kulongedza kwina sikuli bwino, ndipo ena sagwirizana ndi kugwiritsa ntchito sing'anga, yomwe imayenera kusintha kulongedza; Koma ikagwiritsidwa ntchito, chodzazacho chiyenera kusinthidwa kukhala chapakati. Mukasintha filler, kanikizani mozungulira mozungulira. Msoko uliwonse wa mphete mpaka madigiri 45 ndi woyenera, mphete ndi mphete yotsegula madigiri 180. Kutalika kwapang'onopang'ono kuyenera kuganizira za chipinda chopitilira kukanikiza kwa gland. Pakadali pano, gawo lakumunsi la gland liyenera kuloledwa kukanikiza chipinda chonyamulira mpaka kuya koyenera, komwe nthawi zambiri kumatha kukhala 10-20% yakuya kwathunthu kwa chipinda cholongedza. Kwa mavavu ofunikira kwambiri, Angle yolumikizana ndi madigiri 30. Mizere pakati pa mphetezo imagwedezeka ndi madigiri 120.
Kuwonjezera pa filler pamwamba, mphira O-mphete angagwiritsidwenso ntchito malinga ndi mmene zinthu zilili (chibadwa mphira kukana ofooka alkali m'munsimu 60 digiri Celsius, butadiene mphira kukana mafuta makhiristo pansi 80 digiri Celsius, Fluorine mphira kukana m'munsimu 150 digiri Celsius. zosiyanasiyana zowononga TV) zidutswa zitatu zakhala zikuzunza m'miyoyo polytetrafluoroethylene mphete (kukana m'munsimu 200 madigiri Celsius amphamvu zikuwononga TV) nayiloni mbale mphete (kukana m'munsimu 120 digiri Celsius ammonia, zamchere) kupanga filler. Wosanjikiza wa polytetrafluoroethylene (PTFE) yaiwisi yaiwisi ya tepi imakulungidwa mozungulira chimbale cha asbestos wamba, chomwe chingathe kusintha kusindikiza ndikuchepetsa kuwonongeka kwa electrochemical kwa tsinde la valve. Mukakanikiza zokometsera, tsinde la valve liyenera kuzunguliridwa nthawi yomweyo kuti likhale lofanana ndikuteteza kuti lisafe kwambiri. Gland iyenera kumangidwa mofanana osati kupendekeka.

Chachisanu, ma valve ena ayeneranso kukhala ndi chitetezo chakunja, chomwe ndi kutchinjiriza ndi kuziziritsa. Nthawi zina mizere ya nthunzi yotentha imawonjezedwa pagawo lotsekera. Ndi valavu yamtundu wanji yomwe iyenera kutsekedwa kapena kusungidwa kuzizira, malinga ndi zofunikira zopanga. Kumene sing'anga mu valavu imachepetsa kutentha kwambiri, idzakhudza kupanga bwino kapena kuzizira valavu, muyenera kusunga kutentha, kapena kusakaniza kutentha; Kumene valavu ikuwonekera, yosagwirizana ndi kupanga kapena kuyambitsa chisanu ndi zochitika zina zoipa, m'pofunika kusunga kuzizira. Zida zotetezera ndi asibesitosi, ubweya wa slag, ubweya wa galasi, perlite, diatomite, vermiculite ndi zina zotero; Zida zoziziritsa kukhosi, perlite, thovu, pulasitiki ndi zina zotero
