进口塑料背压阀性能特点 Performance characteristics

在现场取下调整螺丝上的保护帽，旋转调整螺丝，借助管路中的压力表可调至所需压力，可通过调节螺丝在0-0.6Mpa范围内设置背压。和脉冲阻尼器配合使用减少水锤对系统的损坏，保持泵的出水口到背压阀有一定的恒压，保持系统流速均恒。

Remove the protective cap from the adjustment screw on site, rotate the adjustment screw, and use the pressure gauge in the pipeline to adjust to the required pressure. The back pressure can be set within the range of 0-0.6Mpa by adjusting the screw. Working in conjunction with pulse dampers to reduce water hammer damage to the system, maintaining a constant pressure from the pump outlet to the back pressure valve, and maintaining a constant flow rate in the system.
