工作原(yuán)理：

Working principle:

  防爆、安全閥作為壓縮、易爆氣體(tǐ)管道系統中的卸壓裝置。當系統壓力大于表(biǎo)壓力時，防爆膜片則自行破裂(liè)，安全閥闆則自行開啟洩壓，以防止系統發(fā)生(shēng)爆炸，保證生産和人(rén)身(shēn)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(zuò)為輸送氣體管道中的特殊卸壓裝置，可(kě)以根據系統需要，經手動控制或自(zì)動控(kòng)制來完成對管道系統中氣體的排(pái)放或補充，其密封面根據(jù)不同工況、不同溫度，可采用橡膠軟密封或金屬硬密封形式(shì)。

  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、洩爆閥安全膜片，安全閥、安全閥闆根據客(kè)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産品(pǐn)相符(fú)，切不可(kě)盲目安裝使(shǐ)用。

l   安裝(zhuāng)時，清理安全膜(mó)片(piàn)、安全閥闆，不允(yǔn)許有污垢附着，兩法蘭連接時，中間需加密封墊。

l   防爆、安全閥，保護動作後，必須馬上更換安全(quán)膜片或檢查(chá)安全閥闆狀态(tài)。

l   防爆、安全閥應(yīng)随時處(chù)于臨界動作(zuò)狀态，以保護系統。

l   放(fàng)散閥、放風閥(fá)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(shí)應避免撞擊閥門和(hé)安全膜片、安全閥闆及放風閥的傳動(dòng)裝(zhuāng)置。

l  閥門應存放在幹(gàn)燥室内，不允許露天存放或堆置(zhì)，保護安全閥閥闆密封(fēng)面。放散閥，放風(fēng)閥應對傳(chuán)動裝置及傳動部位(wèi)作防鏽、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(wéi)護及檢修：

Maintenance and examination:

l  定期檢查各安全閥，防爆(bào)閥的運行情況。

l  如出現安全閥、防爆閥的安全(quán)膜片爆破後，請在排除系(xì)統故障後(hòu)及時(shí)更(gèng)換安全膜片。

l  對放風閥的執行機構(gòu)定(dìng)期檢查，對傳動部分(fèn)加潤滑油，定期更換(huàn)潤滑(huá)脂。

l  對(duì)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.
