1.Wambafufuzani ma valvekungokwaniritsa kutseka kwa unidirectional ndikutsegula ndi kutseka zokha malinga ndi kusiyana kwapakatikati. Alibe ntchito yowongolera liwiro ndipo amatha kukhudzidwa akatsekedwa. Valve yowunikira madzi imawonjezera kutsekeka kwapang'onopang'ono kotsutsana ndi nyundo pamaziko a ntchito yodula. Pogwiritsa ntchito chipangizo chodzipatulira kuti chiwongolere kuthamanga kwa valve ya valve, ikhoza kuchepetsa mphamvu ya nyundo ya madzi panthawi yobwerera ndikuteteza zipangizo zamakina. (Chithunzi: DN1200).valavu yopendekera yokhala ndi nyundo yolemetsa）

2.Kusiyana kwa kapangidwe kake

Chovala chodziwika bwino chimakhala ndi dongosolo losavuta, lopangidwa ndi thupi la valve, disc, mpando wa valve ndi makina obwezeretsanso (kasupe kapena mphamvu yokoka). Kutsegula ndi kutseka kwake kumadalira kwambiri kukankhira kwa sing'anga. The micro-kukaniza pang'onopang'ono kutseka valavu flanged cheke ali okonzeka ndi pang'onopang'ono kutseka kulamulira limagwirira (monga hydraulic damping ndi kasupe buffer zigawo zikuluzikulu) pa maziko awa, amene akhoza kutseka mu magawo (choyamba mwamsanga kutseka 70% -80%, ndiyeno pang'onopang'ono kutseka gawo lotsala).

(Chithunzi: DN700 tilting cheke valavu ndi nyundo kulemera)

3.Fluid Resistance ndi Water hammer Control

Chifukwa cha zoperewera zamapangidwe, valavu yoyang'ana wamba imakhala ndi kukana kwakukulu kutsogolo komanso kuthamanga kwachangu (0.5 mpaka 1 sekondi), yomwe ingayambitse mosavuta nyundo yamadzi, makamaka kuopseza kwambiri machitidwe othamanga kwambiri komanso othamanga kwambiri. Valavu yoyang'ana gulugufe imachepetsa kukana kutsogolo (ie, "micro-resistance") kudzera m'mapangidwe osinthika ndikuwonjezera nthawi yotseka mpaka masekondi a 3-6, omwe amatha kuwongolera nyundo yamadzi pachimake mkati mwa 1.5 nthawi yogwira ntchito ndikufooketsa kwambiri zotsatira zake.

4.Zigawo zosiyana zogwirira ntchito

Ma valve odziwika bwino ndi oyenerera pa zochitika zokhala ndi mphamvu yochepa (≤1.6MPa), kuyenda kochepa (m'mimba mwake ≤DN200), komanso kusamva nyundo yamadzi, monga mipope yanthambi yoperekera madzi apakhomo ndi malo opangira madzi otentha. Valavu yotsekera pang'onopang'ono yotsekeka yosabwerera ndi yoyenera kupanikizika kwambiri (≥1.6MPa) ndi kayendedwe kake (m'mimba mwake ≥DN250) machitidwe, monga madzi opangira moto okwera m'nyumba, malo akuluakulu a mpope, makina ozungulira madzi ozungulira mafakitale ndi zochitika zina zovuta.

5.Maintenance ndi Mtengo

Ma valve ovomerezeka a cheke alibe zipangizo zovuta, ali ndi chiwerengero chochepa cholephera, ndi chosavuta kusamalira komanso kukhala ndi ndalama zochepa. Chifukwa cha kukhalapo kwa makina otsekera pang'onopang'ono, valavu yotsekera pang'onopang'ono yotsekereza imatha kukumana ndi zovuta monga kutayira kwa mafuta komanso kukalamba kwa masika, zomwe zimapangitsa kuti pakhale kuwongolera pafupipafupi komanso mtengo wake. Komabe, poganizira ntchito yonse yachitetezo chadongosolo, imapereka magwiridwe antchito abwinoko pamikhalidwe yovuta.

Choncho, kusiyana kwakukulu pakati pa awiriwa kumakhala ngati ali ndi ntchito yotsutsana ndi nyundo yotsekedwa pang'onopang'ono: ma valve oyendera cheke amayang'ana kwambiri kutseka koyambirira, pamene ma valve otchinga pang'onopang'ono amachepetsa kukana komanso kugwedezeka chifukwa cha kukhathamiritsa kwapangidwe, kuwapanga kukhala chisankho chokonda kwambiri pazitsulo zothamanga kwambiri komanso zothamanga kwambiri.

Monga wopanga ma valve omwe ali ndi zaka 20, Valve ya Jinbin yakhala ikutsimikizira mtundu wa zinthu ndi ntchito zake. Ngati muli ndi zosowa zina, chonde titumizireni pansipa ndipo mudzalandira yankho mkati mwa maola 24!
