我們多年行業(yè)經(jīng)驗，了解氣體滅火系統比較且在施工過(guò)程中有一定的危險，施工中容易出現一些性事故，存在以下問(wèn)題，同行、項目人員都可以了解一下。下面川消小編為您分析：

We have many years of industry experience and understand that gas fire extinguishing systems are relatively professional and pose certain risks during construction. Some safety accidents are prone to occur during construction, and the following problems exist. Peer and project personnel can learn about them. The following is an analysis by Sichuan Xiaobian:

(1)組合分配系統中聯(lián)動(dòng)控制系統接線(xiàn)錯誤，使啟動(dòng)裝置、選擇閥、防護區未形成應有的對應關(guān)系。如誤將防護區一的聯(lián)動(dòng)啟動(dòng)線(xiàn)路接防護區二的啟動(dòng)裝置上，導致防護區一發(fā)生火災時(shí)滅火劑反而噴放到防護區二中，從而導致滅火失敗。

(1) The wiring error of the linkage control system in the combined distribution system has not resulted in a proper correspondence between the starting device, selector valve, and protection zone. If the linkage starting line of protection zone 1 is mistakenly connected to the starting device of protection zone 2, the extinguishing agent will be sprayed into protection zone 2 instead when a fire occurs in protection zone 1, resulting in a failure to extinguish the fire.

(2)聯(lián)動(dòng)控制系統的聯(lián)動(dòng)關(guān)系設置不正確。如防護區內的空調系統在發(fā)生火情時(shí)不能聯(lián)動(dòng)停止工作，機械排煙設施在發(fā)生火情時(shí)反而聯(lián)動(dòng)啟動(dòng)。這樣一方面會(huì )造成煙氣不易聚集，使探測器無(wú)法及時(shí)探測火災;另一方面在滅火劑噴放滅火時(shí)會(huì )造成滅火劑的流失，使防護區內滅火劑濃度無(wú)法達到滅火濃度，導致滅火失敗。

(2) The linkage relationship setting of the linkage control system is incorrect. For example, the air conditioning system in the protection zone cannot be interlocked and stopped when a fire occurs, and the mechanical smoke exhaust facilities are interlocked and started when a fire occurs. On the one hand, it will make it difficult for smoke to gather, making it impossible for the detector to detect a fire in a timely manner; On the other hand, when the fire extinguishing agent is sprayed, it will cause the loss of fire extinguishing agent, making the concentration of fire extinguishing agent in the protection zone unable to reach the fire extinguishing concentration, leading to fire extinguishing failure.

(3)氣體滅火防護區的開(kāi)口無(wú)法在滅火劑噴放之前聯(lián)動(dòng)關(guān)閉，致使滅火劑流失，降低系統滅火效果。

(3) The opening of the gas fire protection zone cannot be closed before the extinguishing agent is discharged, resulting in the loss of extinguishing agent and reducing the fire extinguishing effectiveness of the system.

(4)無(wú)人值守的房間將滅火系統設置在手動(dòng)工作狀態(tài)，一旦此類(lèi)防護區發(fā)生火情，就無(wú)法及時(shí)啟動(dòng)系統滅火。

(4) In unattended rooms, the fire extinguishing system is set to manual operation. Once a fire occurs in such protective areas, it is not possible to start the system to extinguish the fire in a timely manner.

(5)手動(dòng)啟動(dòng)裝置無(wú)防護措施，容易被人誤操作，造成系統誤噴。

(5) The manual starting device has no protective measures, which can easily be misoperated by people, resulting in incorrect spraying of the system.

(6)系統中設備管道未按規范要求進(jìn)行接地，有可能在雷擊或靜電的作用下引起系統的誤動(dòng)作。

(6) The equipment pipelines in the system are not grounded according to the specification requirements, which may cause misoperation of the system under the action of lightning or static electricity.

(7)防護區圍護結構及門(mén)窗不滿(mǎn)足耐火極限不宜低于0.5h，承受內壓的允許壓強不宜低于1200Pa的要求，或者未按照設計規范要求設置泄壓口?；馂陌l(fā)生或滅火劑噴放時(shí)容易引起防護區圍護結構及門(mén)窗破損，造成滅火劑流失，滅火失敗。

(7) The enclosure structure and doors and windows of the protection zone do not meet the requirements that the fire resistance limit should not be less than 0.5h, and the allowable pressure to withstand internal pressure should not be less than 1200Pa, or the pressure relief port is not set in accordance with the design specifications. When a fire occurs or the extinguishing agent is sprayed, it is easy to cause damage to the enclosure structure and doors and windows of the protection area, resulting in the loss of the extinguishing agent and failure to extinguish the fire.

(8)系統安裝完畢，投入運行時(shí)未將電磁閥或者瓶頭閥處的限位裝置拆除，造成火災時(shí)，系統無(wú)法正常啟動(dòng)。

(8) When the system is installed and put into operation, the electromagnetic valve or the limit safety device at the bottle head valve is not removed, resulting in a fire and the system being unable to start normally.

(9)系統安裝時(shí)，安裝人員隨意改動(dòng)滅火劑輸送管道的位置，管路上增加彎頭，使滅火劑輸送的阻力增加，導致滅火劑無(wú)法在規范要求的噴放時(shí)間內噴放完畢，影響系統的滅火效果。

(9) During system installation, the installer randomly changes the position of the fire extinguishing agent delivery pipeline, adding elbows to the pipeline, which increases the resistance of the fire extinguishing agent delivery, resulting in the failure of the fire extinguishing agent to be discharged within the specified discharge time, affecting the fire extinguishing effect of the system.

(10)組合分配系統中啟動(dòng)氣體單向閥的安裝位置直接決定各個(gè)氣體滅火防護區的滅火劑的噴放數量。施工時(shí)啟動(dòng)氣體單向閥的位置安裝有誤會(huì )導致氣體滅火防護區的實(shí)際滅火劑的噴放數量與滅火劑設計用量不同，從而可能導致防護區內滅火劑濃度過(guò)高或不足。

(10) The installation position of the starting gas one-way valve in the combined distribution system directly determines the amount of extinguishing agent sprayed in each gas fire protection zone. The incorrect installation of the gas one-way valve during construction may result in a difference between the actual amount of extinguishing agent sprayed in the gas fire protection zone and the designed amount of extinguishing agent, which may lead to a high or insufficient concentration of extinguishing agent in the protection zone.

(11)施工時(shí)未按照規范要求設置管道支吊架，為節省成本隨意減少支吊架的數量，導致系統在噴放時(shí)管道震動(dòng)。嚴重時(shí)會(huì )造成管網(wǎng)脫落。

(11) During construction, pipe supports and hangers were not installed in accordance with the requirements of the specification, and the number of supports and hangers was arbitrarily reduced to save costs, resulting in pipe vibration during the system spraying. In severe cases, it can cause the pipe network to fall off.

(12)儲存裝置在搬運過(guò)程中不注意保護，因碰撞原因有可能造成瓶頭閥損壞，造成滅火劑的泄漏。嚴重的則可能導致瓶頭閥打開(kāi)，造成滅火劑釋放，引發(fā)危險。

(12) Failure to protect the storage device during handling may result in damage to the bottle head valve and leakage of fire extinguishing agent due to collision. If it is serious, it may cause the bottle head valve to open, causing the release of fire extinguishing agent and causing danger.

此外日常檢查不到位，鋼瓶滅火劑或啟動(dòng)氣體泄漏未及時(shí)發(fā)現，一旦發(fā)生火情，系統無(wú)法啟動(dòng)或者噴放到防護區內的滅火劑量不足而影響滅火效果。更多使用問(wèn)題就來(lái)我們網(wǎng)站http://www.guizhouhuli.net咨詢(xún)吧！

In addition, daily inspections are not in place, and leakage of steel cylinder fire extinguishing agent or starting gas is not detected in a timely manner. In the event of a fire, the system cannot be started or the amount of fire extinguishing injected into the protective zone is insufficient, which affects the fire extinguishing effect.
