川消消防雨淋系統(tǒng)的組成及各部安裝要點(diǎn)
來(lái)源：http://www.xintli.net/ 日期：2022-06-09
雨淋系統(tǒng)通常由三部分組成：火災(zāi)探測(cè)驅(qū)動(dòng)控制系統(tǒng)；自動(dòng)控制組動(dòng)作閥系統(tǒng)；帶開放式噴水器的自動(dòng)噴水滅火系統(tǒng)。其中，火災(zāi)探測(cè)傳輸控制系統(tǒng)可以使用火災(zāi)探測(cè)器、傳輸管網(wǎng)或易熔合金鎖來(lái)啟動(dòng)群動(dòng)閥。火災(zāi)探測(cè)器、輸電管網(wǎng)、易熔鎖控制是自動(dòng)控制手段。
The deluge system usually consists of three parts: fire detection drive control system; Automatic control group action valve system; Automatic sprinkler system with open sprinkler. Among them, the fire detection transmission control system can use the fire detector, transmission pipe network or fusible alloy lock to start the group operated valve. Fire detector, power transmission pipe network and fusible lock control are automatic control means.
當(dāng)使用自動(dòng)裝置時(shí)，還應(yīng)提供手動(dòng)裝置作為備用。可使用群動(dòng)閥系統(tǒng)自動(dòng)控制，雨淋閥或雨淋閥加濕報(bào)警閥。雨淋系統(tǒng)可分為空管雨淋系統(tǒng)和充水式雨淋系統(tǒng)兩種。充水雨淋系統(tǒng)的滅火速度比空管雨淋系統(tǒng)快。
When automatic devices are used, manual devices shall also be provided as backup. Group valve system can be used for automatic control, deluge valve or deluge valve humidification alarm valve. The deluge system can be divided into air pipe deluge system and water filled deluge system. The fire extinguishing speed of water filled deluge system is faster than that of air pipe deluge system.
在實(shí)際應(yīng)用中，可根據(jù)保護(hù)對(duì)象的要求選擇合適的形式。在實(shí)際應(yīng)用中，雨淋系統(tǒng)可能有許多不同的組件，但它們的工作原理大致相同。雨淋系統(tǒng)采用開放式噴水器，因此在整個(gè)保護(hù)區(qū)內(nèi)同時(shí)進(jìn)行噴水。
In practical application, the appropriate form can be selected according to the requirements of the protected object. In practical application, the deluge system may have many different components, but their working principles are roughly the same. The deluge system adopts an open sprinkler, so it sprays water at the same time in the whole protection area.
當(dāng)發(fā)生火災(zāi)時(shí)，火災(zāi)探測(cè)系統(tǒng)感應(yīng)到火情，控制雨淋閥打開，連接水源和雨淋管網(wǎng)，灑水器噴水滅火。
In case of fire, the fire detection system senses the fire, controls the deluge valve to open, connects the water source and deluge pipe network, and sprays water with sprinklers to extinguish the fire.
濕式報(bào)警閥通常閥瓣前后水壓相同（水通過(guò)導(dǎo)管內(nèi)的水壓平衡孔保持閥瓣前后水壓平衡）。由于閥瓣的重量與閥瓣前后水的總壓力不同，閥瓣處于關(guān)閉狀態(tài)（閥瓣上方的總壓力大于閥下方的總壓力核）。
Wet alarm valves usually have the same water pressure before and after the valve clack (water keeps the water pressure before and after the valve clack balanced through the water pressure balance hole in the conduit). Because the weight of the valve disc is different from the total pressure of the water before and after the valve disc, the valve disc is closed (the total pressure above the valve disc is greater than the total pressure core below the valve disc).
發(fā)生火災(zāi)時(shí)，封閉式灑水器會(huì)噴水。由于水壓平衡孔來(lái)不及補(bǔ)水，報(bào)警閥上方的水壓下降。這時(shí)閥瓣前面的水壓大于閥瓣后面的水壓，所以閥瓣打開，立管和管道打開。同時(shí)，水沿著報(bào)警閥的環(huán)形槽進(jìn)入延時(shí)裝置、壓力開關(guān)和液壓報(bào)警鈴，發(fā)出火警信號(hào)，啟動(dòng)消防泵。
In case of fire, the enclosed sprinkler will spray water. As the water pressure balance hole is too late to make up water, the water pressure above the alarm valve drops. At this time, the water pressure in front of the valve disc is greater than that behind the valve disc, so the valve disc is opened, and the riser and pipeline are opened. At the same time, water enters the time delay device, pressure switch and hydraulic alarm bell along the annular groove of the alarm valve to send out a fire alarm signal and start the fire pump.
施工安裝要點(diǎn)
Key points of construction and installation
川消濕式報(bào)警閥、延時(shí)裝置和液壓報(bào)警鈴的安裝位置周圍應(yīng)預(yù)留足夠的維修空間，以確保在短的停機(jī)時(shí)間內(nèi)進(jìn)行維修。報(bào)警閥離地高度為1.2m。
Sufficient maintenance space shall be reserved around the installation position of Chuanxiao wet alarm valve, time delay device and hydraulic alarm bell to ensure maintenance within the shortest shutdown time. The alarm valve is 1.2m above the ground.
液壓警鈴是濕式報(bào)警閥的主要部件。水警鈴應(yīng)設(shè)在有人值守地點(diǎn)附近。與報(bào)警閥的連接管道直徑應(yīng)為20mm，總長(zhǎng)不應(yīng)超過(guò)20m，安裝高度不應(yīng)超過(guò)2m，并應(yīng)有排水設(shè)施。
The hydraulic alarm bell is the main component of the wet alarm valve. The marine police bell shall be set near the attended place. The diameter of the connecting pipe with the alarm valve shall be 20mm, the total length shall not exceed 20m, the installation height shall not exceed 2m, and there shall be drainage facilities.
濕式報(bào)警閥、延時(shí)裝置和液壓報(bào)警鈴之間的安裝距離、安裝高度和管道直徑應(yīng)保證其功能滿足相關(guān)要求。
The installation distance, installation height and pipe diameter between wet alarm valve, time delay device and hydraulic alarm bell shall ensure that their functions meet relevant requirements.
濕式報(bào)警閥、緩速器和液壓鐘罩應(yīng)能使用常用工具進(jìn)行安裝和現(xiàn)場(chǎng)維護(hù)。

濕式報(bào)警閥的控制區(qū)域根據(jù)口徑等參數(shù)而有所不同。
The control area of wet alarm valve varies according to the diameter and other parameters.
