金属活动硬密封刀
闸阀activities of hard sealing knife gate valve
活动硬密封
刀闸阀，包括阀体、闸板、阀座、金属
密封圈，阀座固定在阀体上，金属密封圈与阀体呈阶梯活动配合与阀座呈凹凸球面活动配合，金属密封圈与阀座的结合面处设置O型密封圈，阀座与阀体接合处设有密封圈，阀体底部设有与阀体一体成型的锲块，闸板的底部设有与阀体底部锲块相吻合的斜面，当闸板下移至阀体底部时，锲块能挤压闸板与金属密封紧密接触。此硬密封结构突破了以往硬密封不能打压的缺陷，显著提高了密封效果。适合于那些要求耐磨，含有固体颗粒的介质
管道中使用。专利号：(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)
