4.Kumanga m'nyengo yozizira, kuyesedwa kwa madzi pa kutentha kwapansi pa zero.

Zotsatira zake: Chifukwa chakuti kutentha kuli pansi pa zero, chitolirocho chidzaundana mofulumira panthawi ya kuyesa kwa hydraulic, zomwe zingapangitse kuti chitoliro chizizizira ndi kusweka.

Miyezo: Yesani kuyesa kuthamanga kwa madzi musanamangidwe m'nyengo yozizira, ndikuchotsani madzi mupaipi ndi valavu mukatha kuyesa kukakamiza, apo ayi valavu ikhoza kuchita dzimbiri, ndipo kuopsa kungayambitse kuzizira.

5.Flange ndi gasket ya kugwirizana kwa chitoliro sizili zolimba mokwanira, ndipo ma bolts ogwirizanitsa ndi ochepa kapena ochepa m'mimba mwake.Chitoliro cha mphira chimagwiritsidwa ntchito pakuwotcha chitoliro, pad pawiri kapena pad yopendekera imagwiritsidwa ntchito ngati chitoliro chamadzi ozizira, ndipo chitoliro cha flange chimasweka mu chitoliro.

Zotsatira: olowa flange si zolimba, ngakhale kuonongeka, kutayikira chodabwitsa.Flange gasket yotulukira mu chitoliro imawonjezera kukana koyenda.

Miyezo: Mapaipi ndi ma gaskets ayenera kukwaniritsa zofunikira pakupanga mapaipi ogwirira ntchito.

The flange gaskets Kutentha ndi madzi otentha mapaipi ayenera kukhala mphira asbestos gaskets;The flange gasket wa madzi ndi ngalande chitoliro ayenera kukhala mphira gasket.

Mzere wa flange sudzaphulika mu chubu, ndipo bwalo lakunja liyenera kuzungulira ku dzenje la bolt la flange.Palibe pedi yokhazikika kapena ma gaskets angapo omwe angayike pakati pa flange.Kutalika kwa bawuti wolumikiza flange kuyenera kukhala kosakwana 2mm poyerekeza ndi kabowo ka flange.Kutalika kwa mtedza wotuluka wa ndodo ya bawuti kuyenera kukhala 1/2 ya makulidwe a mtedza.

6.Sewage, madzi amvula, mapaipi a condensate samachita mayeso otsekedwa amadzi adzabisika.

Zotsatira: Itha kutayikira, ndikupangitsa kuti ogwiritsa ntchito awonongeke.Kusamalira kumakhala kovuta.

Miyezo: Kuyesa kwamadzi otsekedwa kuyenera kuyang'aniridwa ndikuvomerezedwa mosamalitsa malinga ndi zomwe zafotokozedwa.Anakwiriridwa mobisa, mu denga, pakati pa mipope ndi zonyansa zina zobisika, madzi amvula, mipope condensate, etc., kuonetsetsa kuti palibe kutayikira.

7. Kutsegula ndi kutseka kwa valve pamanja, mphamvu zambiri
Zotsatira: kuwonongeka kwa ma valve opepuka, olemetsa kumabweretsa ngozi zachitetezo

Miyezo:

Gudumu lamanja kapena chogwirira cha valavu yamanja chimapangidwa molingana ndi anthu wamba, poganizira mphamvu ya malo osindikizira ndi mphamvu yotseka yofunikira.Chifukwa chake simungagwiritse ntchito zingwe zazitali kapena manja atali kusuntha bolodi.Omwe amazolowera kugwiritsa ntchito ma wrench ayenera kusamala kwambiri kuti asagwiritse ntchito mphamvu zambiri, apo ayi ndizosavuta kuwononga malo osindikizira, kapena kuswa gudumu lamanja ndi chogwirira.Tsegulani ndi kutseka valavu, mphamvu ayenera kukhala yosalala, osati amphamvu zimakhudza.Kwa valavu ya nthunzi, isanatsegulidwe, iyenera kutenthedwa pasadakhale, ndipo condensate iyenera kuchotsedwa, ndipo potsegula, iyenera kukhala yodekha momwe mungathere kuti mupewe zochitika za nyundo yamadzi.

Vavu ikatsegulidwa kwathunthu, gudumu lamanja liyenera kusinthidwa pang'ono, kuti ulusi pakati pa zolimba, zisawonongeke.Pa mavavu otseguka, kumbukirani momwe tsinde ilili yotseguka komanso yotsekedwa kuti musamenye chapakatikati chakumtunda mukatsegula.Ndipo n'zosavuta kuona ngati kutsekedwa kwathunthu ndikwachilendo.Ngati diski ikugwa, kapena zinyalala zazikulu zimayikidwa pakati pa chisindikizo cha spool, malo a tsinde la valve ayenera kusinthidwa pamene valve yatsekedwa kwathunthu.

Pamene payipi ikugwiritsidwa ntchito koyamba, pali zonyansa zambiri zamkati, valavu imatha kutsegulidwa pang'ono, kuthamanga kwapamwamba kwa sing'anga kungagwiritsidwe ntchito kutsuka, ndiyeno kutsekedwa mofatsa (singathe kutsekedwa mwamsanga, kuteteza zotsalira). zonyansa kuvulaza kusindikiza pamwamba), ndiyeno anatsegula kachiwiri, kotero mobwerezabwereza kangapo, flushing dothi, ndiyeno kuika mu ntchito yachibadwa.Kawirikawiri tsegulani valavu, malo osindikizira amatha kukhala ndi zonyansa, ndipo ayenera kutsukidwa ndi njira yomwe ili pamwambayi ikatsekedwa, ndiyeno imatsekedwa.

Ngati handwheel kapena chogwirira chawonongeka kapena kutayika, chiyenera kufananizidwa nthawi yomweyo, ndipo sichingasinthidwe ndi mbale yosinthika, kuti mupewe kuwonongeka kwa tsinde la valve ndi kulephera kutsegula ndi kutseka, zomwe zimapangitsa kuti pakhale ngozi pakupanga.Zofalitsa zina, pambuyo poti valavu yatsekedwa kuti izizirike, kotero kuti ziwalo za valve zichepetse, wogwiritsa ntchitoyo ayenera kutsekedwa kachiwiri pa nthawi yoyenera, kuti malo osindikizira asasiye msoko wabwino, mwinamwake, sing'anga kuchokera kumtsinje wabwino. pa liwiro lalikulu, n'zosavuta kuwononga kusindikiza pamwamba.

Ngati muwona kuti opaleshoniyo ndi yovuta kwambiri, fufuzani chifukwa chake.Ngati kulongedza kuli kolimba kwambiri, kumatha kumasuka bwino, monga valve stem skew, iyenera kudziwitsa ogwira ntchito kuti akonze.Ma valve ena, mu malo otsekedwa, gawo lotseka limakulitsidwa ndi kutentha, zomwe zimapangitsa kuti zikhale zovuta kutsegula;Ngati ayenera anatsegula pa nthawi ino, mukhoza kumasula valavu chivundikiro ulusi theka kutembenukira kwa wina, kuchotsa nkhawa tsinde, ndiyeno kukoka handwheel.
