德寶德burkert2012型截止閥,burket氣動角座閥,burkert角座閥,寶德氣動閥
德寶德burkert2012型截止閥是常規(guī)截止閥的變型。在該閥門中，閥瓣和閥座通常是基于柱塞原理設計的。閥瓣磨光成柱塞與閥桿相連接，密封是由套在柱塞上的兩個彈性密封圈實現(xiàn)的。兩個彈性密封圈用一個套環(huán)隔開，并通過由閥蓋螺母施加在閥蓋上的載荷把柱塞周圍的密封圈壓牢。彈性密封圈能夠更換，可以采用各種各樣的材料制成，該閥門主要用于“開”或者“關”，但是備有特制形式的柱塞或特殊的套環(huán)，也可以用于調節(jié)流量。
德寶德burkert2012型截止閥閥體的結構形式有直通式、直流式和直角式。直通式是zui常見的結構，但其流體的阻力zui大。直流式流體阻力較小，多用于含固體顆?；蛘扯却蟮牧黧w。直角式閥體多采用鍛造，適用于較小通經、較高壓力的的截止閥。
