Mavharuvhu anokamurwa nemazita saizi/pressure/temperature/material/connection/kubata

Mavharuvhu anokamurwa nesaizi yezita / kudzvanywa / tembiricha / zvinhu / kubatana / kubata Kuora kwekemikari kwesimbi kunoenderana nekupisa, mechanical mutoro wezvikamu zvinokweshana, kugadzikana kwemasarufidhi ari mumidziyo yekuzora uye kuramba kwavo asidi, nguva yekubatana ne medium uye catalytic mhedzisiro yesimbi pane nitriding process, chiyero chekushandurwa kwemamorekuru ezvinhu zvinoora kuita simbi, etc. 1, kuparara kwevharuvhu, kunowanzo nzwisiswa sevharuvhu simbi mumakemikari kana electrochemical nharaunda nekuparadzwa. Sezvo ngura ichiitika mukudyidzana kunongoerekana kwaitika pakati pesimbi nenzvimbo dzakatenderedza, nzira yekuparadzanisa simbi kubva kune yakatenderedza nharaunda kana kushandisa zvimwe zvisiri-metallic synthetic zvinhu zvave kunetsa. 2. Zvinonyatsozivikanwa kuti kukuvadzwa kwesimbi kunokanganisa zvakanyanya pahupenyu, kuvimbika uye hupenyu hwebasa revhavha. Chiito chemakanika uye corrosive agents pasimbi zvakanyanya kuwedzera huwandu hwese hwekupfeka pane yekubata kumeso. Valve panguva yekushanda, kupesana kwepamusoro pehuwandu hwekupfeka. Panguva yekushanda kwevharuvhu, nzvimbo dzekukwesha dzinopfekwa nekukuvadzwa semhedzisiro yenguva imwe chete yemechani chiito uye kemikari kana electrochemical kusangana pakati pesimbi nenharaunda. Kuvharuvhu, pombi yayo inoshanda mamiriro ekunze akaoma; Kuvapo kwehydrogen sulfide, carbon dioxide uye mamwe organic acids mumafuta, gasi rechisikigo uye reservoir mvura kunowedzera simba rinoparadza resimbi pamusoro, nokudaro nokukurumidza kurasikirwa kukwanisa kwayo kushanda. 3, nekuda kwekuora kwekemikari yesimbi kunoenderana nekupisa, mechanical load ye friction parts, lubricating materials ine sulfide uye acid yayo kuramba kugadzikana uye yepakati kuonana nguva uye simbi pane nitriding process yecatalytic action, kuora kwemamorekuru echinhu. pamusoro pesimbi yekutendeuka kumhanya uye zvichingodaro. Nokudaro, nzira yekudzivirira kwesimbi yevharuvhu (kana chiyero) uye kushandiswa kwevharuvhu yekugadzira yave imwe yemadingindira ekutsvaga kweindasitiri yevharuvhu. 4, simbi vharafu anticorrosion, inogona kunzwisiswa sevhavha yesimbi yakavharidzirwa kuchengetedza mamiriro ekudzivirira kubva pakuora (sependi, pendi, mafuta ekuzora, nezvimwewo), kuitira kuti vharafu ingave mukugadzira, kuchengetedza, kutakura. kana mukushandiswa kwese kwese kwese hakuna kusvibiswa. 5, simbi valve anticorrosion nzira inoenderana neinodiwa yekudzivirira nguva, yekufambisa uye kuchengetedza mamiriro, maitiro evharuvhu maitiro uye zvinhu, hongu, kufunga nezve hupfumi mhedzisiro yekubvisa anticorrosion. Kukamurwa kwemavharuvhu zvichienderana nezita rekuti dhayamita/kudzvanywa/tembiricha/material/connection mode/operation modhi. 3, "hombe dhayamita vharafu" Zita dhayamita DN350-1200mm vharafu 4, "hombe dhayamita vharafu" zita dhayamita dhayamita DN≥1400mm vharafu Mavharuvhu anorondedzerwa sezita saizi mavharuvhu 1, "diki caliber vharafu" zita dhayamita DN≤40mm vharafu 2, "pakati caliber vharafu" zita dhayamita DN50-300mm vharafu 3, "hombe caliber vharafu" zita dhayamita DN350-1200mm vharafu 4, "hombe dhayamita vharafu" zita dhayamita DN≥1400mm vharafu Kurongwa kwezita rekumanikidza mavharuvhu 1, "vacuum vharafu" kushanda kumanikidza kwakaderera. kupfuura yakajairwa mumhepo yekumanikidza vharafu 2, "yakaderera vharafu" zita rekumanikidza PN≤ 1.6mpa vharafu 3, "yepakati vharafu vharafu" zita rekumanikidza PN2.5-6.4mpa vharafu 4, "high pressure vharafu" nominal pressure PN10.0-80.0mpa vharafu 5, "super high pressure valve" zita rekumanikidza PN≥100MPA vharafu Zvinoenderana nepakati tembiricha tembiricha vharafu 1, "yakakwirira tembiricha vharafu" T > 450 ℃ vharafu 2, "yepakati tembiricha vharafu" 120 ℃≤ T ≤450 ℃ vharafu 3, "yakajairika tembiricha vharafu" -40℃≤ T ≤120℃ vharafu 4, "yakaderera tembiricha vharafu" -100℃≤ T ≤-40℃ vharafu 5, "** tembiricha vharafu" T
