Mfundo yogwirira ntchito ya valve yoyang'ana mbale ziwiri

Valve yoyendera mbale ziwiriH77X gulugufe mbale ndi semicircles awiri, ndi kasupe anakakamizika Bwezerani, kusindikiza pamwamba kungakhale thupi stacking kuwotcherera kuvala zosagwira zakuthupi kapena akalowa mphira, osiyanasiyana ntchito, kusindikiza odalirika. Amagwiritsidwa ntchito m'makampani, kuteteza chilengedwe, kuchiritsa madzi, madzi okwera kukwera kwamadzi ndi chitoliro cha ngalande, kuteteza kusuntha kwapakati.

Mfundo yogwiritsira ntchito valavu ya butterfly check:
Chovala choyang'ana pa mbale yapawiri ya H77X disc ndi yaying'ono, ndipo kutalika kwake kwa valavu kumatha kuchepetsedwa. Chimbale cha agulugufe cheke valavu amasuntha kokha pafupi pakati madzimadzi, ndi kutalika kwa valavu akhoza kutsika. Choncho, valavu ili ndi mawonekedwe osakanikirana. Vavu ndi yooneka ngati mapiko. Chimbalecho ndi chotseguka.
Pamene agulugufe amayang'ana valavu madzimadzi akuyenda, kazungulira kagawo ka valavu kamakhala kakang'ono, ndipo chimbale cha valve chikhoza kutsegulidwa mwamsanga. Ndipo pamapeto pake, nyundo yolemera imachoka pakatikati, kuthandiza diski ya valve kuti ifike pamalo otseguka, ndipo imatha kugwira ntchito yokhazikika, yopanda mphamvu ya kutuluka kwa madzi, kotero kuti kukana kuchitapo kanthu kumakhala kochepa. Choncho, pamene madzimadzi ali abwino, kutaya kwamadzimadzi kumakhala kochepa.

Makhalidwe a zinthu za valve cheki:
1, voliyumu yaying'ono, kulemera kopepuka, kapangidwe kakang'ono, kosavuta kusamalira.
2, mbale ya valavu yogwiritsira ntchito mbale yapawiri yokhala ndi mapangidwe awiri a torsion kasupe, imatha kupanga mbale ya valve mwamsanga.
3, chifukwa cha liwiro kutseka, angalepheretse sing'anga backflow, kuchotsa madzi nyundo wamphamvu.
4, valavu thupi kapangidwe kutalika ndi yaing'ono mu kukula, zabwino okhazikika.
5, unsembe yabwino, akhoza kuikidwa mu yopingasa ndi ofukula mbali ziwiri za payipi.
6, kuti mukwaniritse chisindikizo chonse, kuchuluka kwa kutayikira kwa hydrostatic test ndi ziro.
7.Kudalirika kogwiritsa ntchito, ntchito yabwino yotsutsana ndi kusokoneza.

Muyezo wapawiri mbale chowotcha valavu cheke:
1. Kukula kwa kugwirizana kwa Flange: GB/T1724.1-98
2. Kutalika kwapangidwe: GB / T12221-1989, ISO5752-82

Valavu yoyang'ana pawiri imadziwikanso kuti valavu yoyendera, ndi mtundu wa valavu yodziwikiratu molingana ndi kusiyanasiyana kwamadzimadzi isanachitike komanso pambuyo pa valavu, ntchito ya valavu ya butterfly ndikungolola kuti madziwo aziyenda mbali imodzi, kuteteza. iwo kuchokera ku reverse flow. Vavu yoyang'ana pakhomo ili ndi mitundu iwiri yamadzi ndi gasi. Ma valve onse amadzimadzi ndi gasi okhala ndi mainchesi pansi pa 100 mm amapangidwa ndi mtundu wa silinda. Madziwo akalowa mu valve yowunikira, doko la valve liyenera kuthana ndi kukana kwa masika.
Choncho, madzimadzi amakhala ndi kutayika kwa mphamvu pamene akudutsa mu valve yowunika. Kasupe wa valve yowunikira gasi kwa chitoliro chobwerera ayenera kusankhidwa kukhala ofewa kuti achepetse kupsinjika kwapang'onopang'ono. Ubwino wa valavu yopendekera yojambulidwa ndi tubular ndikuti imatha kukhazikitsidwa mbali iliyonse, kuphatikiza kumtunda, pansi, kopingasa komanso kolowera.
DN125 mm amapangidwa ndi yopingasa. Valovu iyi ili ndi mtundu umodzi wokha wogwiritsa ntchito mpweya.
Mipando ya valve ya mitundu iwiri yomwe ili pamwambayi imapangidwa ndi chitsulo, imodzi yofewa ndi imodzi yolimba imatha kuonetsetsa kuti kutsekedwa kumakhala kolimba, pisitoni (mpando wapakati pa valve) imakhala ndi mphamvu yowononga, imatha kuthandizira kugunda. mpweya kuyenda, valavu pakamwa kutsegula ndi kutseka bwino zitsulo pachimake si zophweka kuthyoka.

Kupatula apo, ndife kampani ya TWS Valve ndipo tili ndi zaka zopitilira 20 popanga ndi kutumiza mavavu.Reilient Butterfly Valve, Vavu ya Chipata, Chongani valavu, Vavu ya Mpira, Cholepheretsa Kubwerera Kumbuyo,Balancer Valvendi Air Releasing Valve ndizinthu zathu zazikulu.
