Tsanangudzo yevhavha uye zvikamu zvichaenderana nezvinodiwa zvemapepa ekugadzira mapepa
1, ivocheki vharafumodhi inofanirwa kuratidzwa zvinoenderana neNATIONAL chiyero chenhamba zvinodiwa.Kana iyo bhizinesi chiyero, inofanirwa kuratidza tsananguro yakakodzera yemuenzaniso.
2, ivocheki vharafukushanda kumanikidza, zvinodiwa ≥ pombi kushanda kumanikidza, pasina kukanganisa mutengo wenzvimbo, vharafu inogona kumira kumanikidza kunofanirwa kunge kwakakura kupfuura iyo chaiyo yekumanikidza pombi;Chero rutivi rwevhavha runofanira kukwanisa kumira 1.1 nguva yevhavha yevhavha pasina kubuda;Valve yakavhurika mamiriro, muviri wevharuvhu unofanirwa kumira zvakapetwa kaviri kudiwa kwevhavha.
3, cheki vharafumazinga ekugadzira, anofanirwa kutsanangura hwaro hweNATIONAL chiyero nhamba, kana chiyero chebhizinesi, chibvumirano chekutenga chinofanira kusungirirwa kune gwaro rebhizinesi.
Sarudza cheki valve zvinhu
1. Valve zvinhu, se grey cast iron pombi zvishoma nezvishoma hazvikurudzirwe kushandiswa, iyo valve body material inofanirwa kunyanya ductile cast iron, uye inoratidza nhamba yemhando uye chaiyo yemuviri uye kemikari yekuongorora data yekukanda.
2, hunde zvinhu, edza kustainless simbi hunde (20Cr13), hombe dhayamita vharafu inofanirawo kuva Stainless simbi yakamisikidzwa hunde.
3, zvinhu zvenzungu, uchishandisa ndarira yealuminium yakakandwa kana ndarira yealuminium yakakandwa, uye kuoma uye kusimba kwakakura kupfuura hunde.
4, stem bushing material, kuoma kwayo uye simba haifaniri kunge yakakura kudarika dzinde, uye mumamiriro ekunyudzwa mumvura uye dzinde, muviri wevharuvhu haugadziri electrochemical corrosion.
5. Zvinhu zvekuisa chisimbiso pamusoro:
Mhando dzevhavha dzakasiyana, nzira dzekuisa chisimbiso uye zvinhu zvinodiwa zvakasiyana;
(2) Yakajairwa wedge gedhi vharafu, mhete yemhangura, kugadzirisa maitiro, nzira yekukuya inofanira kutsanangurwa;
(3) Yenyama, kemikari uye hutano yekuyedza data yeyakapfava chisimbiso gedhi vharafu uye valve ndiro lining zvinhu;
(4) Vhuruvha yebutterfly inofanira kuratidza chinhu chakavharika pamusoro pemuviri wevharuvhu uye chisimbiso chepamusoro pandiro yeshavishavi;Yavo yemuviri uye kemikari yekuongorora data, kunyanya hutano hwerabha zvinodiwa, anti-kuchembera kuita, kupfeka kuramba;Rubha uye epDM rabha rinowanzo shandiswa, uye recycled rabha inorambidzwa zvachose.
6, vharafu shaft kurongedza
(1) Nekuti mavharuvhu ari mupombi network anowanzo kuvhurwa uye kuvharwa zvisingaite, kurongedza kunodiwa kusashanda mumakore mashoma, kurongedza hakusi kuchembera, uye chisimbiso chinochengetwa kwenguva refu;
(2) Valve shaft kurongedza kunofanirawo kutakura kuvhurika nekuvhara kazhinji, kuita chisimbiso chakanaka;
(3) Maererano nezvinodiwa pamusoro apa, valve shaft filler haishanduki kwehupenyu hwose kana kupfuura makore gumi;
(4) Kana kurongedza kuchida kuchinjwa, dhizaini yevhavha inofanira kufunga nezvematanho ekutsiva pasi pemamiriro ekumanikidzwa kwemvura.
Tarisa bvunzo yekushanda kwevhavha
1. Kana imwe dhizaini yevhavha ichigadzirwa mumabhechi, kuita kunotevera kuchaedzwa nechiremera:
Kuvhura uye kuvhara torque yevhavha pasi pekushanda nesimba;
(2) pasi pekumanikidzwa kwekushanda, nguva inoenderera yekuvhura uye kuvhara kwevhavha inogona kuve nechokwadi;
(3) Ivhavha iri mupombi yekufambisa mvura mamiriro ekuyerera kwekudzivirira kweyekuonekwa.
2. Miedzo inotevera inofanira kuitwa vharafu isati yabuda mufekitari:
(1) Kana vharuvhu yakavhurwa, muviri wevhavha unofanirwa kutakura kaviri kudzvanywa kwemukati kwevhavha inoshanda yekumanikidza kukosha;
(2) Pasi pemamiriro akavharwa, mativi ose evhavha zvichiteerana pasi pe11 nguva yevhavha yekumanikidza kukosha, hapana kubuda;Asi simbi chisimbiso butterfly vharafu, leakage ukoshi haina mukuru pane zvakakodzera zvinodiwa
Internal and outside anticorrosion of check valve
1, vharafu muviri (kusanganisira giya bhokisi) mukati nekunze, kutanga inofanira kupfurwa inoputika jecha yekuchenesa ngura, kuedza kupfapfaidza electrostatic poda isiri-chepfu epoxy resin, ukobvu kusvika 0?Kupfuura 3 mm.Hombe valve electrostatic spraying isiri-chepfu epoxy resin yakaoma, inofanirawo kubhurwa, kupfapfaidzwa nependi yakafanana isina chepfu epoxy.
2. Zvose zvikamu zvemuviri wevharuvhu neplate yevharuvhu zvinoda anticorrosion yakazara.Kune rumwe rutivi, haizove ngura kana yakanyoroveswa mumvura, uye hapazovi nemagetsi emagetsi pakati pesimbi mbiri.Zvikamu zviviri zvepasi rakatsetseka kuderedza kusagadzikana kwemvura.
3. Zvinodiwa zvehutano zve anticorrosive epoxy resin kana pende mumutumbi wevharuvhu inofanira kuongororwa nemasimba ane masimba anowirirana.Kemikari uye zvimiro zvemuviri zvinofanirwa kusangana nezvinodiwa.
Kurongedza kwevhavha uye kutakura
1. Mativi maviri evhavha anofanira kugadziriswa neplate yekudzivirira chiedza.
2. Mavharuvhu epakati uye madiki anofanira kusungwa netambo yemashanga uye kutakurwa mumidziyo.
3, hombe dhayamita vharafu zvakare ine yakapfava yemapuranga furemu yakagadzika kurongedza, kuitira kudzivirira kukuvadzwa panguva yekufambisa
