湖(hú)北澳牌閥業有限公司，歡迎您! 今天(tiān)是：
工作原(yuán)理：
Working principle:
防爆、安全閥作為壓縮、易爆氣體管道系統中的(de)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(yǐ)防止系統發生爆炸，保證生産和人身安全。
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(zuò)為輸送氣體管道中的特殊(shū)卸壓裝置，可以根(gēn)據系統需要，經手動控制或自動控(kòng)制來完成對管道系統中氣體的排(pái)放或補充，其密封面根據不同(tóng)工況(kuàng)、不同溫度，可采用橡膠軟密封或金(jīn)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(zhuāng)及調試：
Installation and regulation:
l 防爆、安全閥(fá)作(zuò)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(quán)膜片，安全閥、安(ān)全閥闆根據客戶系統****安(ān)全壓力而(ér)定。使用時(shí)，必須核對工況性能參數是否與該産品相符，切不可盲目安(ān)裝使用。
l 安裝時，清理安全膜(mó)片(piàn)、安全閥闆，不允許有污垢(gòu)附着(zhe)，兩法蘭連接時，中間(jiān)需加密封(fēng)墊。
l 防爆、安全閥，保護(hù)動作後，必須馬上更換(huàn)安全膜片或檢查安全閥闆狀态。
l 防爆、安全閥應(yīng)随時(shí)處于臨界動作狀态，以保護系統。
l 放散閥、放風閥的安裝(zhuāng)條件必須保證(zhèng)人員安全，便于操作與觀(guān)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(bì)免撞擊閥門和安全(quán)膜片(piàn)、安全閥闆及放風閥的傳動裝(zhuāng)置。
l 閥門應存放在幹(gàn)燥室内，不允許(xǔ)露天存(cún)放或堆置，保護安全閥閥闆密封(fēng)面。放散閥，放(fàng)風閥應對傳動裝置及傳動部位作防鏽、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.
維護及檢修：
Maintenance and examination:
l 定期檢(jiǎn)查各安全閥，防爆閥的(de)運行情況。
l 如出(chū)現安全閥、防爆(bào)閥的安全膜片爆破後，請在排(pái)除系統故障後(hòu)及時更換安全(quán)膜片。
l 對(duì)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(bì)狀況要定期檢查，及時更換(huàn)。
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.
訂(dìng)貨須知：
Information for order:
l 選用訂貨時，請參照産品樣本注明産品(pǐn)規(guī)格、型号及技術參數（使用溫度、設備(bèi)工(gōng)況、介質(zhì)性質及工作壓力等）。
l 需傳動裝置的閥門(mén)其執(zhí)行器為普通型，不帶任何相關配件，您(nín)若有特殊要求（防爆、戶外等），請(qǐng)在(zài)合同中注明。
l 表格中未列(liè)的規格、用于特殊介質或其它特殊要求(qiú)，請與(yǔ)我公司經銷部、技術部聯系，可為您(nín)另行設計制造。
l Please indicate the type, model and technical parameter (using temperature, working condition of equipment and characteristic of medium etc) referring to the product sample when you place an order.
l The actuator is normal type without any special corresponding accessory if the valve needs transmission device. If you have special demand (anti-explosion and outdoors etc), please indicate it in the contract.
l If you have other special demand, need special medium or the date that is not listed in the table, please contact with our department of market and technology. We can design and manufacture for you especially.
