主要技术参数
1、型号:J11W-16T
2Select high-quality copper materials and adopt red punching hot forging process;
3、工作介质为水、油、气等(视阀门具体情况而定),不宜用于黏度较大、带颗粒、易结焦、易沉淀的介质;
4, working temperature t≤120℃;
5The nominal pressure is 1.6MPa.
特点与结构
1、截止阀主要用于切断介质、调节和节流。由于阀瓣开与关之间行程小,密封面又能承受多次启闭,适用于需要频繁开关的场合;
2、截止阀结构比闸阀简单,制造与维修都较方便;
3、密封面不易磨损及擦伤,密封性好,启闭时阀瓣与阀体密封面之间无相对滑动,因而磨损与擦伤均不严重,密封性能好,使用寿命长;
4、启闭时,阀瓣行程小,最大开启高度一般仅为阀座通道直径的25%-30%,因此比闸阀小的多,所以截止阀高度比闸阀小,但结构长度比闸阀长;
5, the opening and closing torque is large, the opening and closing is difficult, and the opening and closing time is principal;
6, The fluid resistance is large. Because the medium channel in the valve body is tortuous, the fluid resistance is large and the power consumption is large.
