一．FISHER閥門放大器2625產(chǎn)品介紹
FISHER閥門放大器2625
Fisher 2625 系列體積增壓器與節(jié)流控制閥上的定位器結(jié)合使用，以提高沖程速度。2625NS 是核服務(wù)版本，使用彈性材料組件，可以更好地承受高溫和輻射環(huán)境。2625 和 2625SST 經(jīng)認(rèn)證可用于安全儀表系統(tǒng) (SIS) 應(yīng)用。
特征
當(dāng)突然發(fā)生大的輸入變化時(shí)，提供快速執(zhí)行器行程所需的體積。
整體旁路限制調(diào)節(jié)增壓器響應(yīng)，使執(zhí)行器平滑運(yùn)動(dòng)跟隨緩慢的信號(hào)變化。
軟閥座提供緊密關(guān)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(wěn)態(tài)精度的情況下，根據(jù)需要允許執(zhí)行器的高行程速度。
經(jīng)認(rèn)證可用于安全儀表系統(tǒng) (SIS) 應(yīng)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(shí)以 1:1 的比例再現(xiàn)氣動(dòng)信號(hào)。
增壓器采用固定死區(qū)、軟閥座結(jié)構(gòu)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(xiàn)的定位器飽和問(wèn)題?？烧{(diào)節(jié)的整體旁路限制對(duì)于系統(tǒng)穩(wěn)定性是必要的。這種調(diào)整不會(huì)影響容積增壓器的死區(qū)，但確實(shí)允許控制閥響應(yīng)小的輸入信號(hào)變化而不會(huì)犧牲穩(wěn)態(tài)精度。
它還允許助推器在發(fā)生大而快速的輸入信號(hào)變化時(shí)提供大容量輸出以進(jìn)行快速?zèng)_程。
這些具有固定最小死區(qū)的大容量容積增壓器旨在顯著提高大型執(zhí)行器的行程速度。
只要執(zhí)行器的信號(hào)波動(dòng)保持在通過(guò)調(diào)節(jié)增壓器中的均衡/旁通閥確定的死區(qū)范圍內(nèi)，執(zhí)行器就會(huì)保持其正常的緩慢和穩(wěn)定的響應(yīng)。
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.
