一．FISHER閥門放大器2625產品介紹

FISHER閥門放大器2625

Fisher 2625 系列體積增壓器與節流控制閥上的定位器結合使用，以提高沖程速度。2625NS 是核服務版本，使用彈性材料組件，可以更好地承受高溫和輻射環境。2625 和 2625SST 經認證可用于安全儀表系統 (SIS) 應用。

特征

當突然發生大的輸入變化時，提供快速執行器行程所需的體積。

整體旁路限制調節增壓器響應，使執行器平滑運動跟隨緩慢的信號變化。

軟閥座提供緊密關閉，以減少不必要的空氣消耗并消除定位器繼電器的飽和。

在不降低定位器穩態精度的情況下，根據需要允許執行器的高行程速度。

經認證可用于安全儀表系統 (SIS) 應用。

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閥門放大器1000/3000系列介紹及選型

RK閥門放大器通常用于在需要輸入隔離或增加流量時以 1:1 的比例再現氣動信號。

增壓器采用固定死區、軟閥座結構和整體旁路限制，以消除不具備這些功能的容積增壓器可能出現的定位器飽和問題�？烧{節的整體旁路限制對于系統穩定性是必要的。這種調整不會影響容積增壓器的死區，但確實允許控制閥響應小的輸入信號變化而不會犧牲穩態精度。

它還允許助推器在發生大而快速的輸入信號變化時提供大容量輸出以進行快速沖程。

這些具有固定最小死區的大容量容積增壓器旨在顯著提高大型執行器的行程速度。

只要執行器的信號波動保持在通過調節增壓器中的均衡/旁通閥確定的死區范圍內，執行器就會保持其正常的緩慢和穩定的響應。

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.
