泄爆窗是一種能夠在爆炸發(fā)生時迅速釋放爆炸壓力,以保護人員和建筑物安全的特種窗戶。
泄爆窗通常具有以下特點:
1. 高強度:能夠承受一定程度的爆炸沖擊。
2. 快速泄爆:在爆炸瞬間迅速打開,釋放壓力。
3. 輕質(zhì)材料:以減輕窗戶自身重量,減少爆炸帶來的影響。
泄爆窗常用于工業(yè)廠房、化工廠、鍋爐房、危險品倉庫等存在爆炸危險的場所,是防爆安全設(shè)施的重要組成部分。

泄爆天窗典型做法先整理泄爆窗定義:
泄爆窗是一種特種鋼窗,設(shè)計用于在建筑物內(nèi)外氣壓差達到一定數(shù)值時自動打開,釋放氣體,降低內(nèi)部氣壓,以保護建筑物內(nèi)的人員和財產(chǎn)。泄爆窗通常采用經(jīng)機構(gòu)認(rèn)證的泄爆螺栓系統(tǒng),具有可靠的泄爆性能,并且可以根據(jù)客戶對氣壓差的不同要求進行定制生產(chǎn)?。通常在工業(yè)民用廠房鍋爐房,危險品倉庫等應(yīng)用的輕質(zhì)泄壓窗(重量不超過60kg/m2)。有保溫型泄爆窗和采光型泄爆窗兩類,泄爆值通常在20-40PSF,在建筑物室內(nèi)發(fā)生爆炸或燃燒時屋內(nèi)氣體壓力隨之急劇上升,泄爆窗通過泄爆配件或裝置使窗開啟并釋放壓力以控制爆炸的產(chǎn)生或使破壞程度達到小。針對工況企業(yè)、廠房車間、鍋爐房等危險易燃易爆場所,泄爆將所產(chǎn)生的壓力泄于室外,以減少沖擊波對建筑物結(jié)構(gòu)造成的傷害。泄爆窗功能分析:① 泄爆門窗選用材料能夠滿足使用時的泄壓要求② 泄爆壓力值設(shè)置為:墻面20-40pfs,屋面60-90pfs,且同時滿足當(dāng)?shù)仫L(fēng)荷載要求。按照中華人民共和國國家標(biāo)準(zhǔn)《鍋爐房設(shè)計規(guī)范》GB50041第15.1.2條規(guī)定:“鍋爐房的外墻,樓地面或屋面,應(yīng)有相應(yīng)的防爆措施,并應(yīng)有相當(dāng)于鍋爐間占地面積10%的泄壓面積”當(dāng)泄壓面積不能滿足上述要求時,可采用在鍋爐房的內(nèi)墻和頂部(頂棚)敷設(shè)金屬減壓板作補充。

防爆泄爆類門窗產(chǎn)品主要用于存在爆炸危險的建筑物,目的是為了防爆及泄爆,使建筑內(nèi)外不受爆炸沖擊波危害并有效的阻止爆炸危害的延續(xù)。Explosion-proof and explosion-venting door and window products are mainly used in buildings that are at risk of explosion. The purpose is to prevent explosion and explosion, so that the inside and outside of the building will not be harmed by explosion shock waves and effectively prevent the continuation of explosion hazards.防爆門是爆炸物在被保護的建筑物或房間的外部爆炸時(外爆),在門洞口處設(shè)置的具有防護沖擊波、碎片及火焰作用的門(門開啟時為外開)。當(dāng)爆炸物在室內(nèi)爆炸時(內(nèi)爆),且等效靜荷載≤1000 KPa時,防爆門也可用于防內(nèi)爆(門開啟時為內(nèi)開),在空氣沖擊波作用下門扇自動轉(zhuǎn)向關(guān)閉狀態(tài)。The Blast-proof doors are doors to anti shock waves, debris and flames when explosives explode outside the protected building. When the explosive is indoors and the equivalent static load is ≤1000 KPa, the B-type Blast-proof door can also be used to anti the implosion from automatically closing the door leaf.抗爆窗是能抵抗來自建筑物外部爆炸沖擊波的特種建筑固定外窗,對爆炸沖擊波、爆炸碎片和火焰具有防護作用??贡坝蓛?nèi)外窗和聯(lián)鎖裝置等組成,并且內(nèi)外窗扇不得同時開啟。當(dāng)無法滿足內(nèi)外窗扇交替開啟要求時需進行設(shè)計。內(nèi)外窗扇均由氣缸實現(xiàn)開啟,如需要其他開啟方式時可與我司聯(lián)系進行特殊訂貨。The Blast-proof window is a special building material that can resist the explosion shock wave from the outside of the building, and has a protective effect on the explosion shock wave, the explosive debris and the flame. Applicable to the anti-explosion room of the dangerous workshop (anti-blast compartment), suitable for places where the equivalent static load is less than or equal to 1000KPa. If it is greater than this value, special design is required.?The inner and outer windows are opened by the cylinder. If you need other opening methods, you can contact us for special order.?泄爆門的門扇部分是由許多扇泄爆窗組成的,在給定的開啟壓力作用下泄爆窗能夠打開泄壓口,而在泄爆之后又能關(guān)閉泄壓口,在泄爆之后經(jīng)過簡單處理是可以繼續(xù)使用的,泄爆壓力值達到10KPa~20KPa時泄爆門上的泄爆窗可以開啟。泄爆門均為外開門,門扇上的泄爆窗均向外開啟。Its door leaf is composed of a number of pressure relief windows that open automatically under a given pressure and can be closed after pressure relief. After the pressure relief, it can be used continuously after simple treatment. When the pressure value reaches 10KPa~20KPa, the pressure relief window on the pressure relief door can be automatically opened.泄爆窗是一種泄爆(泄壓)裝置,它是在給定的開啟壓力作用下能夠打開泄壓口而在泄爆之后又能關(guān)閉泄壓口的可繼續(xù)使用的外窗。泄爆壓力值達到10KPa- -20KPa時泄瀑窗可開啟。The pressure relief window is an external window that can be used continuously. The pressure relief port can be opened under a given pressure and the pressure relief port can be closed after the pressure relief is completed. The pressure relief window can be opened when the pressure value reaches 10KPa- -20KPa.泄爆窗是易碎的泄爆輕型窗,是為抗爆間室提供泄壓面的輕型外窗。在泄爆窗室外側(cè)設(shè)置現(xiàn)澆鋼筋混凝土抗爆屏院。輕型窗的采光部分采用塑性透光材料。The pressure relief window is a fragile lightweight window. It is a lightweight exterior window that provides a pressure relief surface for the anti-blast chamber. A cast-in-place reinforced concrete anti-explosive screen is installed on the outside of the room equipped with a B-type pressure relief window. The lighting part of the window is made of plastic light-transmitting material.
