Mfundo yogwirira ntchito ya valavu yowunikira mbale ziwiri

Valavu yowunikira mbale ziwiriMbale ya gulugufe ya H77X ili ndi ma semicircles awiri, ndipo kasupe amakakamizidwa kuti akhazikitsenso, kusindikiza pamwamba pa thanki kungakhale kopangidwa ndi thupi lokhala ndi zinthu zosagwira ntchito kapena labala, ndipo imagwiritsidwa ntchito mosiyanasiyana, kusindikiza kodalirika. Imagwiritsidwa ntchito m'makampani, kuteteza chilengedwe, kuchiza madzi, madzi okwera nyumba ndi chitoliro chotulutsira madzi, kuti zisawononge kayendedwe ka madzi m'nyumba.

Mfundo yogwiritsira ntchito valavu yowunikira gulugufe:
Malo oyendetsera valavu yoyezera ya H77X yokhala ndi mbale ziwiri ndi ochepa, ndipo kutalika kwa valavu komwe kumatsatira kumatha kuchepetsedwa. Disiki ya valavu yoyezera ya gulugufe imayenda pafupi ndi pakati pa madzi, ndipo kutalika kwa valavu kumatha kuchepetsedwa. Chifukwa chake, valavu ili ndi kapangidwe kakang'ono. Vavuyo ndi yofanana ndi mapiko. Disikiyo ndi yotseguka kwambiri.
Madzi a valavu yoyezera gulugufe akamayenda, mtunda wozungulira wa valavu ndi wochepa, ndipo valavu imatha kutsegulidwa mwachangu. Ndipo pamapeto pake, nyundo yolemera imachoka pakati, zomwe zimathandiza valavu kuti ifike pamalo otseguka, ndipo imatha kugwira ntchito yokhazikika, yopanda mphamvu ya madzi, kotero kuti kukana kuchitapo kanthu kumakhala kochepa. Chifukwa chake, madzi akakhala abwino, kutayika kwa kuthamanga kwa madzi kumakhala kochepa.

Zinthu zomwe zimapanga ma valve oyezera:
1, voliyumu yaying'ono, kulemera kopepuka, kapangidwe kakang'ono, kosavuta kusamalira.
2, mbale ya valavu pogwiritsa ntchito mbale ziwiri zokhala ndi masika awiri ozungulira, imatha kutseka mbale ya valavu mwachangu.
3, chifukwa cha kutseka kwa liwiro, zimatha kuletsa kuyenda kwapakati, kuchotsa nyundo yamadzi yolimba.
4, kutalika kwa kapangidwe ka thupi la valavu ndi kakang'ono kukula kwake, kulimba kwake kumakhala bwino.
5, kukhazikitsa kosavuta, kungayikidwe mbali ziwiri zopingasa ndi zowongoka za payipi.
6, kuti tikwaniritse chisindikizo chonse, kuchuluka kwa kutayikira kwa mayeso a hydrostatic ndi zero.
7. Kugwiritsa ntchito bwino, ntchito yabwino yoletsa kusokonezedwa.

Muyezo wa valavu yowunikira mbale ziwiri:
1. Kukula kwa kulumikizana kwa Flange: GB/T1724.1-98
2. Kutalika kwa kapangidwe: GB / T12221-1989, ISO5752-82

Valavu yowunikira mbale ziwiri imadziwikanso kuti valavu yowunikira, ndi mtundu wa valavu yodziyimira yokha malinga ndi kusiyana kwa kuthamanga kwa madzi isanayambe komanso itatha valavu, ntchito ya valavu yowunikira gulugufe ndikulola madzi kuyenda mbali imodzi yokha, kuwaletsa kuti asayende mobwerera m'mbuyo. Valavu yowunikira yapakhomo ili ndi mitundu iwiri ya kugwiritsa ntchito madzi ndi mpweya. Mavavu onse owunikira madzi ndi mpweya okhala ndi mainchesi osakwana 100 mm amapangidwa ndi mtundu wa silinda. Madzi akalowa mu valavu yowunikira, doko la valavu liyenera kuthana ndi kukana kwa kasupe.
Chifukwa chake, madziwo amataya mphamvu akamadutsa mu valavu yowunikira. Kasupe wa valavu yowunikira mpweya wa chitoliro chobwezera mpweya ayenera kusankhidwa kuti akhale ofewa kuti achepetse kutayika kwa mphamvu pang'ono. Ubwino wa valavu yowunikira yopangidwa ndi chubu iyi ndikuti imatha kuyikidwa mbali iliyonse, kuphatikiza mmwamba, pansi, mopingasa komanso mopendekera.
Ma DN125 mm amapangidwa ndi chopingasa. Valavu yoyezera iyi imagwiritsa ntchito mpweya wamtundu umodzi wokha.
Mipando ya ma valavu ya mitundu iwiri yomwe ili pamwambapa ya ma valavu owunikira gulugufe imapangidwa ndi chitsulo, imodzi yofewa ndi ina yolimba imatha kuonetsetsa kuti kutseka kuli kolimba, pisitoni (mpando wapakati wa ma valavu) imakhala ndi mphamvu yonyowa, imatha kusewera mphamvu yoteteza mpweya kuyenda bwino, ndipo valavu yotsegula pakamwa pake ndi kutseka bwino siivuta kuswa.

Kupatula apo, ndife kampani ya TWS Valve ndipo tili ndi zaka zoposa 20 zokumana nazo popanga ndi kutumiza ma valve.Valavu Yolimba ya Gulugufe, Vavu ya Chipata, Vavu Yowunikira, Vavu ya Mpira, Choletsa Kubwerera M'mbuyo,Valavu Yolinganizandi Air Releasing Valve ndi zinthu zathu zazikulu.
