Ndeapi matambudziko akajairika uye mhinduro dzevhavhavhavha panguva yekushandiswa?
Butterfly vharafu nekuda kwehukuru hwayo hudiki uye chimiro chakareruka, chave chimwe chezvinonyanya kushandiswa mavharuvhu muindasitiri, yakawanda uye yakawanda inoshandiswa kune simba remagetsi emvura, kudiridza, kugovera mvura yekuvaka uye kudhiraivha, mainjiniya ekanzuru uye mamwe mapombi masisitimu, anoshandiswa kugura kana kupindirana kuyerera kwezvinotenderera media kuyerera kushandisa. Zvadaro butterfly valve mukushandiswa kwezvinetso zvinoda kutarisirwa uye mhinduro kune chii, nhasi tichave takananga kunzwisisa.
Butterfly valve yekuisa zvinhu zvinoda kutariswa:
1.Usati waiswa, tapota simbisai chigadzirwa chekuita uye midhiya inoyerera museve inopindirana nekufamba kwemamiriro ekushanda, uye ichava mhango yevhavha yakacheneswa, usabvumira tsvina mumhete yekuisa chisimbiso uye butterfly plate yakanamatira kune zvinhu zvekunze, isina kucheneswa zvisati zvambobvumirwa kuvhara ndiro ye butterfly, kuitira kuti irege kukuvadza mhete yekuvhara.
2.Disc ndiro kugadzwa kutsigira flange inokurudzirwa kushandisa inokosha flange butterfly vharafu.
3.Yakaiswa pakati pepombi kana nzvimbo yemativi maviri epombi, nzvimbo yakanakisisa yekuisa vertical, haigoni kuiswa kumusoro.
4. Kushandiswa kwechido chekugadzirisa kuyerera, kune zvinyorwa, magetsi, pneumatic actuators yekutonga.
5. Open uye kuvhara kakawanda shavishavi vharafu, inenge mwedzi miviri, vanofanira kuvhura honye giya bhokisi kavha, tarisa kana ruomba zvakajairika, anofanira kuchengeta uwandu ruomba.
6.Chengetedza kana zvikamu zvekubatanidza zvakatsikirirwa, ndiko kuti, kuve nechokwadi chekuisa chisimbiso chekutakura, asiwo kuve nechokwadi kuti valve stem rotation inoshanduka.
7.Metal seal butterfly valve zvigadzirwa hazvina kukodzera kuiswa pamagumo epombi, zvakadai sezvinofanira kuiswa pamagumo epombi, unoda kutora fitted outlet flange, kudzivirira kuvhara mhete kuunganidza kwekumanikidzwa, pamusoro pechinzvimbo.
8.Kuiswa kwevhavha yevhavha uye kushandiswa kwemhinduro yekugara uchitarisa kushanda kwevhavha, yakawana zvikanganiso panguva yakakodzera.
Zvinogoneka zvinokonzeresa kukundikana: kuvhara pamusoro pevuza
1.Valve ndiro, kuvhara pamusoro pefodha marara
2.Valve ndiro, kuisa chisimbiso pamusoro pekuvhara nzvimbo inopindirana neisina kururama
3.Outlet side configuration inokwira flange mabhaudhi asina kuenzana simba kana mabhaudhi asina kusimba
4.Pressure test direction haisi maererano nezvinodiwa zvepakati pekuyerera kwekutungamira.
Kubvisa nzira
1.Kubvisa tsvina, kuchenesa mukati mevhavha yevhavha
2.Gadzirisa giya rehonye kana magetsi, pneumatic actuator kugadzirisa screws kuti uwane nzvimbo chaiyo yekuvharwa kwevhavha.
3.Kutarisa ndege yakasungirirwa yeflange uye kusungirirwa kwebhoti, inofanira kunge yakamanikidzwa zvakafanana
4.Maererano nemuseve wekuisa chisimbiso nzira yekumanikidza
Valve mbiri inoguma kuvuza kutadza kunokonzera
1.Mativi ose ekuvhara gasket kukundikana
2.Pipe flange tightness haisi yunifomu kana kusamanikidzwa
3.Kuvhara mhete kana kuvhara mhete mukukundikana kwegasket
Kubvisa nzira
1.Replace chisimbiso gasket
2.Pressure flange mabhaudhi (uniform force)
3.bvisa mhete yevhavha, shandura mhete yekuvhara uye kukundikana kwegasket.
Butterfly vharafu inogona kukamurwa kuita yepakati mutsara butterfly vharafu uye eccentric butterfly vharafu zvinoenderana nechimiro fomu. Zvinoenderana nechisimbiso fomu inogona kukamurwa kuita nyoro chisimbiso mhando uye yakaoma chisimbiso mhando. Chisimbiso chakapfava chisimbiso chinowanzo shandisa chigaro cherubha chevharuvhu kana chisimbiso cherubha mhete, yakaoma chisimbiso mhando kazhinji inoshandisa simbi mhete yekuisa chisimbiso. Zvinoenderana nemhando yekubatanidza, inogona kukamurwa kuita flange yekubatanidza uye wafer yekubatanidza; zvinoenderana neiyo nzira yekufambisa, inogona kukamurwa kuita bhuku, magetsi, pneumatic uye hydraulic. Tinogona kusarudza akasiyana actuators maererano nemamiriro ekushanda.
