Kana pombi welding, muromo wakashata mushure mepombi hausi pamutsara wepakati, hapana gaka muhuviri, pombi yakakora yemadziro haina foshoro yegororo, uye hupamhi uye kukwirira kwe weld hazvienderane nezvinodiwa zvekodhi yekuvaka. .
Mhedzisiro: iyo pombi isiriyo yekubuda haisi mumutsara wepakati inokanganisa iyo welding mhando uye maonero emhando. Iko hakuna gaka muhuviri, iyo gobvu yemadziro pombi haiite foshoro groove, hupamhi uye kureba kweweld haina kusangana nezvinodiwa zvewelding haigone kusangana nezvinodiwa zvesimba.
Zviyero: mushure mekugadzirisa pombi, pombi haifaniri kuzununguka pamutsara wepakati; mukaha unofanira kusiiwa; pombi hobvu yemadziro inofanira kufoshorwa. Mukuwedzera, hupamhi uye urefu hweweld ichave yakashongedzwa maererano nezvinodiwa.

Iyo pombi inovigwa zvakananga muvhu rakaomeswa nechando uye isina kucheneswa ivhu, uye nzvimbo uye nzvimbo yepombi kutsigira piers hazvina kunaka, uye kunyange muchimiro cheyadhi yakaoma yezvidhinha.
Mhedzisiro: Nekuda kwerutsigiro rusina kugadzikana, pombi yakakuvadzwa mukuita kwekudzosera kumashure compaction, zvichikonzera rework uye kugadzirisa.
Matanho: pombi haizovigwa muvhu rakaomeswa nechando uye isina kucheneswa ivhu, pier spacing inofanirwa kusangana nezvinodiwa zvekuvaka, padhi yekutsigira inofanirwa kuve yakasimba, kunyanya iyo pombi interface, haifanirwe kutakura simba rekugera. Zvidhinha zvinotsigira piers zvinofanirwa kuvakwa nemvura uye jecha slurry kuti ive nechokwadi chekutendeseka uye kusimba.

Iyo yekuwedzera bhoti yeyakagadziriswa pombi yekutsigira zvinhu yakaderera, iyo aperture yekuisa yekuwedzera bhoti yakakura kwazvo kana bhoti yekuwedzera yakaiswa pamadziro ezvidhinha kana kunyange madziro emwenje.
Mhedzisiro: tsigiro yepombi yakasununguka, iyo pombi deformation, kana kutodonha.
Matanho: mabhaudhi ekuwedzera anofanirwa kusarudza zvigadzirwa zvine hunyanzvi, kana zvichidikanwa, zvinofanirwa kutorwa sampuli kuti zviongororwe, nzvimbo yekuisa mabhaudhi ekuwedzera haifanire kunge yakakura kupfuura 2mm yekunze dhayamita yekuwedzera mabhaudhi, mabhaudhi ekuwedzera anofanirwa kuiswa kune kongiri chimiro.

Iyo flange ndiro uye liner hazvina kusimba zvakakwana, uye mabhoti ekubatanidza mapfupi kana akaonda muhupamhi. Rubber pad inoshandiswa pakupisa pombi, cushion kaviri kana padhi yakarerekera pombi yemvura inotonhora, uye flange liner inobudikira muchubhu.
Mhedzisiro: iyo flange plate yekubatanidza haina kusimba, kana kunyange kukuvadza, kuvuza chiitiko. Iyo flange inopinza muchubhu ichawedzera kuyerera kwekudzivirira.
Matanho: Pipe flange ndiro uye liner inofanira kusangana nezvinodiwa pombi dhizaini inoshanda kumanikidza.
Rubber asbestos pad yekudziya uye inopisa mvura yekupa pombi uye mapedhi erabha ekupa mvura uye pombi dzemvura.
Iyo flange liner haifaniri kupinda muchubhu, denderedzwa rekunze kune flange bolt gomba rakakodzera. Hapana padhi yakatemerwa kana mitsara yakawanda ichaiswa pakati peflange. Iyo dhayamita yebhaudhi inobatanidza flange inofanira kunge iri pasi pe 2mm yakakura kupfuura kuvhurika kweplate yeflange, uye kureba kwebhoti tsvimbo inobuda nati inofanira kunge iri 1/2 yeukobvu hwenati.

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 inotora shavishavi vharuvhu.
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 gedhi valve, moto wepombi yekusveta pombi haifaniri kushandisabutterfly valve.
Kunze kwezvo, Tianjin Tanggu Mvura Chisimbiso Valve Co., Ltd. is tekinoroji yepamusoro elastic chigaro vharafu inotsigira mabhizinesi, zvigadzirwa zviri elastic seat wafer butterfly vharafu, lug butterfly vharafu,kaviri flange concentric butterfly vharafu, kaviri flange eccentric butterfly valve, chiyero chevhavha,wafer dual plate check valve, Y-Strainer uye zvichingodaro. PaTianjin Tanggu Mvura Seal Valve Co., Ltd., tinodada nekupa zvigadzirwa zvemhando yepamusoro zvinosangana nepamusoro-soro indasitiri zviyero. 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.
