Fisher氣動(dòng)控制產(chǎn)品適用于需要保護(hù)設(shè)備或最終控制元件的工作條件的應(yīng)用。Fisher費(fèi)希爾377壓力感應(yīng)保衛(wèi)閥用于氣源壓力降至特定點(diǎn)以下,需要特殊閥門/執(zhí)行機(jī)構(gòu)的控制應(yīng)用.費(fèi)希爾377產(chǎn)品文檔, 特性及優(yōu)勢(shì),應(yīng)用規(guī)范. Fisher 377 pressure-sensing trip valve is used for control applications where a specific valve/actuator b is required when supply pressure falls below a specific point. When supply pressure falls below the trip point the trip valve causes the actuator to fail up, lock in the last b, or fail down. When the supply pressure rises above the trip point, the 377 Series trip valve automatically resets, allowing the system to return to normal operation. The trip valve can be top-mounted on a manifold, yoke-mounted, or bracket-mounted to match the application requirements.
Fisher 377 Trip Valve
氣源壓力降至觸發(fā)點(diǎn)以下時(shí),保衛(wèi)閥會(huì)使執(zhí)行機(jī)構(gòu)不能上升,鎖定在上一位置,或不能下降。氣源壓力升至觸發(fā)點(diǎn)以上時(shí),377 系列保衛(wèi)閥會(huì)自動(dòng)重置,讓系統(tǒng)返回正常運(yùn)行狀態(tài)。保衛(wèi)閥可以采用頂部安裝方式安裝在歧管上,也可采用閥桿安裝式或支架安裝式,以適應(yīng)各種應(yīng)用的需求。?
具有成本效益—單個(gè)保衛(wèi)閥與使用三個(gè)單獨(dú)轉(zhuǎn)換閥執(zhí)行失效功能的系統(tǒng)相比,可以降低成本和減少備件需求。單保衛(wèi)閥可極大地簡(jiǎn)化對(duì)管線的需求。
- 模式變換方便—變換為任何失效模式只需一個(gè)微小的連接變化。
- 可調(diào)式保衛(wèi)閥—觸發(fā)點(diǎn)可針對(duì)特殊氣源壓力要求進(jìn)行調(diào)節(jié)。
- 可靠的操作—保衛(wèi)閥的設(shè)計(jì)包含大量薄膜區(qū)域,可活動(dòng)的部件少,可提高有效性能,減少維護(hù)要求并延長(zhǎng)使用壽命
