防爆安全閥

工作原理：

Working principle:

防爆、安全閥作為壓縮、易爆氣體管道系統中的卸壓裝置。當系統壓力大于表壓力時，防爆膜片則自行破裂，安全閥板則自行開啟泄壓，以防止系統發生爆炸，保證生產和人身安全。

The valve is the unloading device of compress easy-exploding pipe. The slice would break itself and the board would open to release pressure automatically when the system pressure is above meter pressure, which can prevent the explosion and protect the production and person’s safety.

放散閥、放風閥作為輸送氣體管道中的特殊卸壓裝置，可以根據系統需要，經手動控制或自動控制來完成對管道系統中氣體的排放或補充，其密封面根據不同工況、不同溫度，可采用橡膠軟密封或金屬硬密封形式。

The discharging air valve and scatter valve is used in the transporting gas pipe system for special discharging device. It can let or supply the gas in the pipe system by manual or automatic control according to the system demand. Rubber soft sealing or metal hard sealing can be adopted in terms of different working condition and temperature.

安裝及調試：

Installation and regulation:

l         防爆、安全閥作為系統終端或旁路終端的安全設備，為法蘭式連接。

l         防爆閥、泄爆閥安全膜片，安全閥、安全閥板根據客戶系統安全壓力而定。使用時，必須核對工況性能參數是否與該產品相符，切不可盲目安裝使用。

l         安裝時，清理安全膜片、安全閥板，不允許有污垢附著，兩法蘭連接時，中間需加密封墊。

l         防爆、安全閥，保護動作后，必須馬上更換安全膜片或檢查安全閥板狀態。

l         防爆、安全閥應隨時處于臨界動作狀態，以保護系統。

l         放散閥、放風閥的安裝條件必須保證人員安全，便于操作與觀察。

l          Anti-exploding or safety valve is the safety equipment on the end of system or side road, which is connected by flanges.

l          Safety film, safety valve and valve board are decided by the max safety pressure of user’s system. Examine the performance parameters of working condition when operate.

l          Clean the safety film and valve board when install and there is no dirt. Add seal cushion between the two flanges.

l          Exchange the safety film or check the state of valve board immediately after protecting action is over.

l         The valve should be in the critical action state at any time in order to protect system.

l          The installation condition must ensure the safety of the operator and make it easy to operate and observe.

運輸保管：

Transportation and protection:

l         運輸時應避免撞擊閥門和安全膜片、安全閥板及放風閥的傳動裝置。

l         閥門應存放在干燥室內，不允許露天存放或堆置，保護安全閥閥板密封面。放散閥，放風閥應對傳動裝置及傳動部位作防銹、防潮處理。

l          Avoid bumping valve gate, safety film, safety valve board and transmission device of discharging air valve when transport the valve.

l          Anticorrosive and dampproof measures should be taken to the transmission devices and parts of the discharging air valve and scatter valve.

維護及檢修：

Maintenance and examination:

l         定期檢查各安全閥，防爆閥的運行情況。

l         如出現安全閥、防爆閥的安全膜片爆破后，請在排除系統故障后及時更換安全膜片。

l         對放風閥的執行機構定期檢查，對傳動部分加潤滑油，定期更換潤滑脂。

l         對密閉狀況要定期檢查，及時更換。

l          Check the working condition of the safety valve and anti-explosion valve regularly.

l          If the safety film of safety valve and anti-explosion valve is demolished, please exchange the safety film in time after solve the failure.

l          Check the actuator of the discharging air valve regularly. Add lubricant to the transmission parts and replace the lubricant grease regularly.

l          Check the sealing condition regularly and replace in time.
