一．FISHER阀门放大器2625产品介绍

 

FISHER阀门放大器2625

 

Fisher 2625 系列体积增压器与节流控制阀上的定位器结合使用，以提高冲程速度。2625NS 是核服务版本，使用弹性材料组件，可以更好地承受高温和辐射环境。2625 和 2625SST 经认证可用于安全仪表系统 (SIS) 应用。

 

特征

当突然发生大的输入变化时，提供快速执行器行程所需的体积。

整体旁路限制调节增压器响应，使执行器平滑运动跟随缓慢的信号变化。

软阀座提供紧密关闭，以减少不必要的空气消耗并消除定位器继电器的饱和。

在不降低定位器稳态精度的情况下，根据需要允许执行器的高行程速度。

经认证可用于安全仪表系统 (SIS) 应用。

 

Fisher 2625 series volume boosters are used in conjunction with a positioner on a throttling control valve to increase stroking speed. The 2625NS is a nuclear service version and uses elastomeric components that better withstand high temperature and radiation environments. The 2625 and 2625SST are certified for use in Safety Instrumented System (SIS) applications.

 

Features

Delivers the volume needed for rapid actuator stroking when large input changes suddenly occur.

Integral bypass restriction tunes the booster response so that smooth actuator motion follows the slow signal changes.

Soft seats provide tight shutoff to reduce unnecessary air consumption and eliminate saturation of positioner relays.

Permits high actuator stroking speeds upon demand without degrading the positioner steady-state accuracy.

Certified for use in Safety Instrumented System (SIS) applications.

R.K.CONTROL阀门放大器1000/3000系列介绍及选型

RK阀门放大器通常用于在需要输入隔离或增加流量时以 1:1 的比例再现气动信号。

 

增压器采用固定死区、软阀座结构和整体旁路限制，以消除不具备这些功能的容积增压器可能出现的定位器饱和问题。可调节的整体旁路限制对于系统稳定性是必要的。这种调整不会影响容积增压器的死区，但确实允许控制阀响应小的输入信号变化而不会牺牲稳态精度。

 

它还允许助推器在发生大而快速的输入信号变化时提供大容量输出以进行快速冲程。

 

这些具有固定最小死区的大容量容积增压器旨在显着提高大型执行器的行程速度。

 

只要执行器的信号波动保持在通过调节增压器中的均衡/旁通阀确定的死区范围内，执行器就会保持其正常的缓慢和稳定的响应。

 

RK Volume Boosters are normally used to reproduce pneumatic signals in 1:1 ratio whenever input isolation or increased flow capacity is required .

 

The booster incorporates fixed deadband, soft seat construction, and an integral bypass restriction to eliminate positioner saturation problems that can occur with volume boosters that do not have these features. Adjustable integral bypass restriction is necessary for system stability. This adjustment does not affect the deadband of the volume booster, but does permit the control valve to respond to small input signal changes without sacrificing steady-state accuracy.

 

It also allows the booster to deliver high-volume output for fast stroking when large, rapid input signal changes occur.

 

These high capacity Volume Boosters with fixed minimum dead band are designed to substantially improve the stroking speeds of large actuators.

 

Actuators retain their normal slow and stable responses as long as their signal fluctuations remain within the dead band limits that are determined by adjustment of the equalizing / by pass valve with in the Booster.
