金屬活動硬密封刀閘閥
activities of hard sealing knife gate valve
活動硬密封刀閘閥,包括閥體、閘板、閥座、金屬密封圈,閥座固定在閥體上,金屬密封圈與閥體呈階梯活動配合與閥座呈凹凸球面活動配合,金屬密封圈與閥座的結合面處設置O型密封圈,閥座與閥體接合處設有密封圈,閥體底部設有與閥體一體成型的鍥塊,閘板的底部設有與閥體底部鍥塊相吻合的斜面,當閘板下移至閥體底部時,鍥塊能擠壓閘板與金屬密封緊密接觸。此硬密封結構突破了以往硬密封不能打壓的缺陷,顯著提高了密封效果。適合于那些要求耐磨,含有固體顆粒的介質管道中使用。號:(200720108250.2)
The activities of hard-seal knife gate valve, including valve, gate, valve seat, metal seals,Valve seat is fixed to the body, the metal seal ring and the valve body ladder of other activities was presented with the convex-concave valve seat spherical surface of other activities, the metal seal The combination with the valve seat ring surface of the set O-ring, valve seat and valve body junction with O-ring, valve and valve body forming with the bottom of the Wedge block, damper and valve at the bottom of the bottom with Wedge block coincide with the slope, when the gate valve at the bottom of the next move when the extrusion ram can carve pieces in close contact with the metal seal. This hard-sealing structure has transcended the old seal can not be suppressed by hard defects, significantly improved the sealing effect.
Suitable for those who require wear-resistant, contains solid particles used in the media pipeline. Patent No.: (200,720,108,250.2)
