Valve ya Mpira wa Kiti cha Metal
Maelezo ya Bidhaa
Sehemu ya kuendesha gari ya valve kulingana na muundo wa valve na mahitaji ya mtumiaji, kwa kutumia kushughulikia, turbine, umeme, nyumatiki, nk, inaweza kuzingatia hali halisi na mahitaji ya mtumiaji kuchagua mode sahihi ya kuendesha gari.
Mfululizo huu wa bidhaa za valves za mpira kulingana na hali ya kati na bomba, na mahitaji tofauti ya watumiaji, kubuni ya kuzuia moto, kupambana na tuli, kama vile muundo, upinzani wa joto la juu na joto la chini inaweza kuhakikisha valve chini ya hali tofauti mara nyingi. kazi, inayotumika sana katika gesi asilia, mafuta, tasnia ya kemikali, madini, ujenzi wa mijini, ulinzi wa mazingira, dawa, chakula na tasnia zingine.
Vipengele
• Vali za mfululizo hutumia chuma cha kughushi au chuma cha kutupwa kama nyenzo ya mwili wao. Muundo unaweza kuwa aina ya kuelea au viunzi vya aina ya mpira wa trunnion.
• Uchakataji wa usahihi wa hali ya juu husababisha mpira wa hali ya juu na upatanishi wa kiti kwa kuzima kwa kasi kuendana na kiwango cha kuvuja cha ANSI B16.104 dass VI.
• Mwelekeo wa mtiririko wa aina inayoelea iliyowekwa ni ya mwelekeo mmoja. Aina iliyopachikwa ya Trunnion ina mwelekeo-mbili kikamilifu na ina uwezo wa kuzuia-na-damu.
• Shughuli zinazotegemewa zenye torati ya chini ya uendeshaji: Kiti kilichopakiwa cha chemchemi ya diaphragm hudumisha mguso wa karibu na mpira kikihakikisha kuzibwa kwa nguvu hata kwa shinikizo la chini. Hii inasababisha torque chini ya ufunguzi na kufunga.
• Sefu ya moto: Mchanganyiko wa viti vya chuma na mihuri ya grafiti huhakikisha uwezo wa usalama wa moto.
• Halijoto ya juu zaidi ya programu za huduma ni hadi 550°C (1022° F). Mpira na kiti vimeimarishwa kwa uwekaji wa juu wa anga za juu. Na ugumu hukutana na HRC 70-72.
• Komesha miunganisho:DIN au flange ya ANSI, weld kitako au weld soketi.
