产品结构特点 Construction features 内螺纹与承插焊锻钢闸阀流体阻力小,启、闭所需力矩较小,可以使用在介质向两方向流动的环网管路上,也就说介质流向不受限制。全开时,密封面受工作介质的冲 蚀比截止阀小。形体结构比较简单,制造工艺性较好,结构长度比较短。 The internal thread and the welded steel gate valve are small in the fluid resistance, and the torque is small, and can be used in the two directions of the loop network tube, which also means that the flow of the medium is not restricted. When open, the sealing cover is less than the closing valve of the working medium. The form structure is relatively simple, the manufacturing process is better, the structure length is shorter. 技术规范 Technical specification 闸阀结构长度和外接尺寸 Main connection dimensions
