进口自动补偿平衡式双闸板平板闸阀性能描述 Performance description

自动补偿平衡式双闸板平板闸阀全封闭结构，防护性能好，密封采用耐磨、耐腐蚀材料制成，各零件互相分离，即使在温度变化时引起变形也仍能保证密封，且不会因高温膨胀而使闸板挤住打不开，在高温、高压情况下，进口一侧闸板设计为可泄压方式、防止由于温度变化而引起的腔内压力异常升高的现象，保证使用安全 RETZ The fully enclosed structure of the automatic compensation balanced double ram flat gate valve has good protection performance. The seal is made of wear-resistant and corrosion-resistant materials, and the parts are separated from each other. Even if the deformation is caused by temperature change, the seal can still be guaranteed, and the ram will not be squeezed and cannot be opened due to high temperature expansion. Under high temperature and high pressure, the ram at the inlet side is designed to be pressure relieving Prevent abnormal pressure rise in the cavity caused by temperature change, and ensure safe use

流量特性分析Flow Charalteristic

带导流孔的平板闸阀，其流量特性等同于同规格的管道，呈等百分比特性，不带导流孔的平板闸阀，其中腔跨度较楔式闸阀小，且属于规则的圆柱体，所以，基本上除压力损失较带导流孔的大外，其余特性基本接近。不带导流孔调节型的平板闸阀其对流量的调节特性优于普通不带导流孔的平板闸阀 retz品牌 The flow characteristic of flat gate valves with a diversion hole is equal to that of pipelines of thesame specification. The characteristic is shown in per centum form. As for valves without a diversion hole, its cavity fly span is smaller than that of wedge gate vales and it is a regular cylindrical object,therefore,characteristics of the valves are similar except that they have a larger pressure loss.Besides, their flux adjustment behavior is better than that of the ones with a deversion hole.
