Izvo zvinotsanangurwa uye mienzaniso yevhavha yakasimwa haisati yasangana nezvinodiwa zvekugadzira.
Semuenzaniso, kudzvinyirirwa kwezita revhavha ishoma pane system test pressure;gedhi vharafu nokuda kwemvura yebazi pombi pombi apo pombi dhayamita isingasviki kana akaenzana 50mm;iyo yakaoma uye inosimuka yekudziya mvura inopisa;uye pombi yekusveta pombi yemoto inotorabutterfly valve.
Mhedzisiro: inokanganisa kuvhurika kwakajairwa nekuvhara kwevhavha uye gadzirisa kuramba, kumanikidza uye mamwe mabasa.Kunyange kukonzera kushanda kwehurongwa, kukuvadzwa kwevhavha kunomanikidzwa kugadzirisa.
Zviyero: Iva neruzivo nechiyero chekushandiswa kwemavharuvhu akasiyana, uye sarudza zvakatemwa uye mhando dzemavharuvhu zvinoenderana nezvinodiwa zvekugadzira.Iyo yekumanikidza yezita revhavha ichasangana nezvinodiwa zve system test pressure.Zvinoenderana nekodhi yekuvaka: vharafu yekumisa ichashandiswa kana iyo dhayamita yepombi isingasviki kana yakaenzana ne50mm;vharafu yegedhi ichashandiswa kana dhayamita yepombi yakakura kupfuura 50mm.Mvura inopisa inopisa yakaoma, vertical control valve inofanira kushandiswa gedhivhavha, mvura yemoto pombi yekusveta pombi haifaniri kushandisa butterfly valve.

Zvishandiso zvikuru, zvishandiso uye zvigadzirwa zvinoshandiswa mukuvaka zvinoshaya magwaro ehunyanzvi hwekuongorora kana zvitupa zvechigadzirwa zvinosangana neazvino nyika kana makurukota.
Migumisiro: unhu husina kukodzera hwepurojekiti, njodzi dzinogona kuitika, haigoni kuendeswa nenguva, inofanira kugadziriswa uye kugadziriswa;zvichikonzera kunonoka kuvaka uye kuwedzera kwevashandi nekuisa zvinhu.
Matanho: Zvishandiso zvikuru, zvishandiso uye zvigadzirwa zvinoshandiswa mukugovera mvura uye mapurojekiti ekudziya zvichave nehunyanzvi magwaro ekuongorora emhando kana zvitupa zvechigadzirwa zvinoenderana neazvino zviyero zvakapihwa nehurumende kana Ministry;Zvichakadaro, zita rechigadzirwa, modhi, yakatarwa, yenyika mhando chiyero kodhi, zuva rekutumira, zita remugadziri nenzvimbo, chitupa chekuongorora kana kodhi icharatidzwa.

Valve inverted
Migumisiro: cheki chevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavharepinyunyunyunyunyunyunyunyunyumavharuvhu ane gwara,kana akaiswa inverted, throttle valve inokanganisa kushanda basa uye upenyu;pressure yekudzikisa valve haishande zvachose, cheki valve inotokonzera njodzi.
Zviyero: vharafu, ine chiratidzo chekutungamira pane muviri wevharuvhu;kana zvisina kudaro, inofanira kunyatsozivikanwa maererano nemutemo wekushanda wevhavha.Iyo valve yevhavha yevhavha yekumira haina asymmetric, iyo fluid inofanirwa kuirega ichipfuura nepakati pemuromo wevharuvhu kubva pasi kusvika kumusoro, kuitira kuti kudzivirira kwemvura kudiki (kunotemwa nechimiro), kuvhurika kwevashandi kuchengetedza (nekuda kwekumanikidza kwepakati. kumusoro), kuvhara svikiro haimanikidzi kurongedza, kugadzirisa nyore.Ichi ndicho chikonzero valve yekumira haigone kugadziriswa.

Ivhavha haiiti kupisa kupisa uye kutonhora matanho
Matanho: mamwe mavharuvhu anofanirwawo kunge aine zvidziviriro zvekunze, uku ndiko kupisa kwekupisa uye kudzivirira kunotonhora.Thermal insulation steam pombi dzimwe nguva inowedzerwa kune insulation layer.Ndeupi rudzi rwevhavha inofanira kuiswa insulated kana kutonhora, maererano nezvinodiwa zvekugadzira.Muchidimbu, apo iyo yepakati muvharuvhu inoderedza tembiricha yakawandisa, ichakanganisa kugadzirwa kwakanaka kana kuomesa vharafu, inoda insulation, kunyangwe kupisa kwekutsvaga;uko vharafu yakafumura, inopesana nekugadzirwa kana kukonzera chando uye zvimwe zvakashata zviitiko, zvinodikanwa kuchengetedza kutonhora.Thermal insulation zvinhu zvinosanganisira asbestos, slag cotton, girazi wool, perlite, diatom ivhu, vermiculite;inotonhora yekudzivirira zvinhu zvinosanganisira cork, perlite, furo, mapurasitiki, nezvimwe.

Ivhavha yekudhonza haina kuisirwa bypass
Matanho: mamwe mavharuvhu, kuwedzera kune anodiwa ekudzivirira zvivakwa, asi zvakare ane bypass uye chiridzwa.Iyo bypass yakaiswa kuti ifambise kuchengetedza kwemusungo wemvura.Mamwe mavharuvhu, akaisawo bypass.Kunyangwe kuisa bypass zvinoenderana nemamiriro evhavha, kukosha uye zvinodiwa zvekugadzira.

Iyo filler haina kuchinjwa nguva dzose
Zviyero: vheji yekuisa, imwe yekuzadza haina kunaka, imwe haienderane nekushandiswa kwemidhiya, inoda kutsiva iyo filler.
Iyo valve inotarisana nezviuru zvemarudzi akasiyana midhiya, uye tsamba yekuzadza inogara yakazadzwa neyakajairwa ndiro midzi, asi kana yashandiswa, kurongedza kunofanirwa kuchinjirwa kune yepakati.
Paunenge uchichinja filler, dzvanya mukati nekutenderera.Mubatanidzwa wega wega wepamakumbo madhigirii 45, uye mhete nemhete yejoinhi madhigirii 180.Kureba kwekurongedza kunofanirwa kufunga nezvemukamuri yekuenderera mberi kwechivharo, uye parizvino, chikamu chezasi chechivharo chinofanira kunge chine kudzika kwakakodzera, iyo inogona kunge iri 10-20% yehupamhi hwese hwekamuri yekurongedza.
Kunze kwezvo, Tianjin Tanggu Mvura Chisimbiso Valve Co., Ltd. ndeye tekinoroji yepamusoro elastic chigaro vharafu inotsigira mabhizinesi, zvigadzirwa zviri elastic seat wafer butterfly valve,lug butterfly valve,kaviri flange concentric butterfly vharafu, kaviri flangeeccentric butterfly valve, vharafu,wafer dual plate check valve, Y-Strainer uye zvichingodaro.PaTianjin Tanggu Mvura Chisimbiso Valve Co., Ltd., tinodada nekupa zvigadzirwa zvemhando yepamusoro zvinosangana nemhando yepamusoro yeindasitiri.Nemavharuvhu edu akasiyana-siyana uye mafittings, unogona kuvimba nesu kuti tipe mhinduro yakakwana yehurongwa hwako hwemvura.Bata nesu nhasi kuti udzidze zvakawanda nezve zvigadzirwa zvedu uye kuti tingakubatsira sei.
