工作原理：

working principle:

  防爆(bào)、安全閥作為壓縮、易爆(bào)氣體(tǐ)管(guǎn)道(dào)系統中的(de)卸(xiè)壓裝置(zhì)。當系統(tǒng)壓力大(dà)于表壓力時，防(fáng)爆膜片(piàn)則自(zì)行(háng)破裂，安(ān)全(quán)閥闆(pǎn)則自行開啟洩(xiè)壓，以(yǐ)防止系統(tǒng)發(fā)生爆(bào)炸(zhà)，保證(zhèng)生産(chǎn)和人身安(ān)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(sàn)閥(fá)、放風(fēng)閥作為輸送氣(qì)體管道中(zhōng)的特殊(shū)卸(xiè)壓裝置，可(kě)以根(gēn)據系(xì)統需(xū)要，經手動控制或自動(dòng)控制來(lái)完成(chéng)對管(guǎn)道系(xì)統中氣體的排(pái)放或(huò)補充，其(qí)密(mì)封面根據(jù)不同(tóng)工況(kuàng)、不(bú)同溫度(dù)，可采(cǎi)用橡膠軟密封或金屬硬(yìng)密封(fēng)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(ān)裝(zhuāng)及調試：

installation and regulation:

l    防(fáng)爆、安(ān)全閥(fá)作為(wéi)系統(tǒng)終端或旁路終端(duān)的安全(quán)設備(bèi)，為法蘭式連(lián)接(jiē)。

l   防爆閥、洩(xiè)爆閥(fá)安全膜片(piàn)，安全(quán)閥、安全(quán)閥闆根(gēn)據客戶系(xì)統****安(ān)全壓力(lì)而定(dìng)。使(shǐ)用時(shí)，必須(xū)核對(duì)工況性(xìng)能參數是否與該産品(pǐn)相(xiàng)符，切(qiē)不可盲(máng)目安裝使(shǐ)用(yòng)。

l   安裝時，清理(lǐ)安全(quán)膜片、安全閥闆(pǎn)，不允許有(yǒu)污垢(gòu)附着，兩法蘭連(lián)接時，中間需加(jiā)密封(fēng)墊(niàn)。

l   防爆、安全閥(fá)，保(bǎo)護動作(zuò)後，必(bì)須馬上更(gèng)換安(ān)全膜片或(huò)檢查(chá)安全閥闆(pǎn)狀态。

l   防爆、安全(quán)閥應(yīng)随時處于(yú)臨界(jiè)動作狀态，以保(bǎo)護系統。

l   放(fàng)散閥、放風(fēng)閥的安裝條件必須(xū)保證(zhèng)人員安全(quán)，便于(yú)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(bǎo)管：

transportation and protection:

l   運輸時應避免(miǎn)撞擊閥(fá)門和安全(quán)膜片、安(ān)全(quán)閥闆(pǎn)及放風閥(fá)的傳(chuán)動裝(zhuāng)置。

l   閥(fá)門應(yīng)存放在幹(gàn)燥室内，不允許露天(tiān)存放或(huò)堆置，保護安全閥閥闆密封面(miàn)。放(fàng)散閥(fá)，放風(fēng)閥應對(duì)傳(chuán)動裝置(zhì)及(jí)傳動部位作防鏽、防(fáng)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(xiū)：

maintenance and examination:

l   定期檢查(chá)各安全閥(fá)，防爆閥的運行情況(kuàng)。

l   如出(chū)現(xiàn)安全閥(fá)、防爆(bào)閥(fá)的安全(quán)膜片(piàn)爆破(pò)後，請(qǐng)在排除系統故(gù)障後及時(shí)更換(huàn)安全(quán)膜(mó)片。

l   對放(fàng)風閥的執(zhí)行機(jī)構定期檢(jiǎn)查，對(duì)傳動(dòng)部分加潤(rùn)滑油(yóu)，定期(qī)更換潤滑脂。

l   對(duì)密閉狀況(kuàng)要定期檢(jiǎn)查，及時更(gèng)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.
