川消干式報警閥安裝之后要如何進行調(diào)試呢？

1、干式報警閥應(yīng)在系統(tǒng)管網(wǎng)試壓、沖洗合格后進行。
1. The dry-type alarm valve shall be carried out after the pressure test and flushing of the system pipe network are qualified.
2、干式報警閥應(yīng)安裝在無冰凍危險的環(huán)境中，要求安裝場所采光充足、采暖好、安裝空間充足。
2. The dry-type alarm valve should be installed in an environment without freezing danger. It is required that the installation site has sufficient lighting, heating and installation space.
3、干式報警閥應(yīng)設(shè)置在、便于操作的位置，閥座法蘭距地面的高度應(yīng)在1.2m左右。
3. The dry alarm valve should be set in a safe and easy to operate position, and the height of the valve seat flange from the ground should be about 1.2m.
4、管網(wǎng)系統(tǒng)安裝干式報警閥前，應(yīng)對供水管網(wǎng)進行清洗，確保供水管網(wǎng)清潔無異物。
4. Before installing the dry alarm valve in the pipe network system, the water supply pipe network should be cleaned to ensure that the water supply pipe network is clean and free of foreign matters.
5、拆下閥蓋和閥蓋墊片，檢查閥瓣是否靈活。確認動作靈活后，安裝閥蓋墊片和閥蓋。
5. Remove the bonnet and bonnet gasket and check whether the disc is flexible. After confirming that the action is flexible, install the bonnet gasket and bonnet.
6、系統(tǒng)內(nèi)安裝干式報警閥，下端接供水管路，上端接系統(tǒng)噴淋管網(wǎng)。注意：干式報警閥必須直立安裝。建議干式報警閥兩側(cè)距離墻面不小于0.5m，正面到墻面距離不小于1.5m。
6. A dry alarm valve is installed in the system, with the lower end connected to the water supply pipeline and the upper end connected to the system spray pipe network. Note: the dry alarm valve must be installed vertically. It is recommended that the distance from both sides of the dry alarm valve to the wall should not be less than 0.5m, and the distance from the front to the wall should not be less than 1.5m.
川消小編提醒，通常，報警閥后面的管網(wǎng)充滿壓力氣體，從水源到報警閥前端的管段充滿壓力水。干式自動噴水滅火系統(tǒng)發(fā)生火災(zāi)時，火源處溫度升高，使火源上方的噴水器打開，管網(wǎng)內(nèi)的壓縮空氣排出，因此管網(wǎng)壓力經(jīng)過報警閥下降，干式報警閥閥前壓力大于閥后壓力，干式報警閥打開，水流配水管網(wǎng)，通過打開的灑水器灑水滅火。
Chuanxiao Xiaobian reminded that usually, the pipe network behind the alarm valve is full of pressure gas, and the pipe section from the water source to the front end of the alarm valve is full of pressure water. When a fire occurs in the dry-type automatic sprinkler system, the temperature at the fire source rises, so that the sprinkler above the fire source is opened, and the compressed air in the pipe network is discharged. Therefore, the pipe network pressure drops through the alarm valve. The pressure in front of the dry-type alarm valve is greater than the pressure behind the valve. The dry-type alarm valve is opened, and the water flows to the water distribution pipe network, and the water is sprinkled through the open sprinkler.
在干式系統(tǒng)中，報警閥上下閥板的壓力保持平衡。當(dāng)系統(tǒng)管網(wǎng)有輕微漏氣時，使用空壓機補充空氣。安裝在供氣管道上的壓力開關(guān)監(jiān)測系統(tǒng)管網(wǎng)的氣壓變化。
In the dry system, the pressure of the upper and lower valve plates of the alarm valve remains balanced. When there is slight air leakage in the system pipe network, use the air compressor to make up air. The pressure switch installed on the gas supply pipeline monitors the pressure change of the system pipe network.
