四通球阀详细说明 |
Q346F/S、 Q9B46F/S 型四通球阀结构特点及用途 1.流体阻力小:球体和阀体的连接管道截面相等,且球体通道采用圆弧连接,介质通过球体时,流体阻力小 2.密封性能好:阀座采用具有一定弹性变形和高强度的PTFE材料,达到良好密封性能,保证了阀门的稳定性/ 3.使用寿命长:阀门的阀芯和光劲材料采用奥氏不锈钢,阀座材料选用PTFE 能达到良好的抗腐蚀性作用,延长了阀门使用寿命. 四通球阀介质流向原理如图所示,"46"型四通球阀只需操作扳手或执行器将球体转动90℃ 可同时对两种介质的流向进行切换,.即方便而迅速实现一阀多用的效果执行标准Carry out the standard 1.设计和制造(Design and manufacture):GB/T12237-1989; API 608 2.检验和试验(Inspection and testing):GB/T13927-1992; API 598 3.法兰连接(The flange joining):JB/T79.1~2-1994;ASME/ANSI 16.5 主要性能规范Chief property and specification 试验压力Test pressure 单位MPa
