The deflection angle of injection mainly depends on the valve port angle and almost has no relation to the valve size, but the reduction coefficient vavies with both of them.
射流的偏转角主要受阀口角度的影响，几乎与阀口尺寸无关；但射流的收缩系数则与两者都有关系。

"This support should be rigid and of sufficient strength to prevent" wind up ", deflection or transfer of abnormal loads to the valve."
