川消干式報(bào)警閥定義自動(dòng)噴水滅火系統(tǒng)中的一種控制閥門。它是在其出口側(cè)充以壓縮氣體，當(dāng)氣壓低于某一定值時(shí)能使水自動(dòng)流入噴水系統(tǒng)并進(jìn)行報(bào)警的單向閥。下面認(rèn)識(shí)下該設(shè)備吧。
Dry alarm valve defines a control valve in automatic sprinkler system. It is a one-way valve filled with compressed gas at its outlet. When the air pressure is lower than a certain value, it can make water automatically flow into the sprinkler system and give an alarm. Now let's meet the equipment.
干式報(bào)警閥的額定工作壓力應(yīng)不低于1.2MPa。干式報(bào)警閥與工作壓力等級(jí)較低的設(shè)備配裝使用時(shí)，允許將閥的進(jìn)出口接頭按承受較低壓力等級(jí)加工，但在閥上須對(duì)額定工作壓力做相應(yīng)的標(biāo)記.
The rated working pressure of dry alarm valve shall not be less than 1.2MPa. When the dry-type alarm valve is used with equipment with lower working pressure level, it is allowed to process the inlet and outlet joints of the valve according to the lower pressure level, but the rated working pressure must be marked on the valve
閥在關(guān)閉位置，閥瓣組件與閥座內(nèi)緣之間少有3mm的半徑間隙。閥座的環(huán)形空間深度不應(yīng)小于3mm,軸與軸套之間的徑向間隙不應(yīng)小于0.125mm。閥瓣軸銷與閥體支承端面之間的軸向間隙不應(yīng)小于0.25mm。
When the valve is in the closed position, there is at least a 3mm radius gap between the disc assembly and the inner edge of the valve seat. The depth of the annular space of the valve seat shall not be less than 3mm, and the radial clearance between the shaft and the shaft sleeve shall not be less than 0.125mm. The axial clearance between the disc shaft pin and the supporting end face of the valve body shall not be less than 0.25mm.

閥體中對(duì)閥的開(kāi)啟起主導(dǎo)作用的任何往復(fù)運(yùn)動(dòng)的導(dǎo)向零件，在活動(dòng)件進(jìn)入固定處的小徑向間隙不應(yīng)小于0.7mm,閥處于伺應(yīng)狀態(tài)時(shí)，活動(dòng)件與固定件的小徑向間隙不應(yīng)小于0.125mm。耐腐蝕的閥瓣導(dǎo)套、軸銷、軸承與其他黑色金屬零件之間的間距不應(yīng)小于3mm。
For any reciprocating guide part in the valve body that plays a leading role in the opening of the valve, the radial clearance between the movable part and the fixed part shall not be less than 0.7mm when the movable part enters the fixed part. When the valve is in the waiting state, the radial clearance between the movable part and the fixed part shall not be less than 0.125mm. The distance between the corrosion-resistant disc guide sleeve, shaft pin, bearing and other ferrous metal parts shall not be less than 3mm.
1、干式報(bào)警閥應(yīng)在系統(tǒng)管網(wǎng)試壓、沖洗合格后進(jìn)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(bào)警閥應(yīng)設(shè)置在無(wú)冰凍危險(xiǎn)的環(huán)境中，要求安裝場(chǎng)所采光充足，采暖良好，有足夠的安裝空間。
2. The dry-type alarm valve should be set in an environment without freezing danger. The installation site is required to have sufficient lighting, good heating and enough installation space.
3、干式報(bào)警閥宜設(shè)置在及易于操作的地點(diǎn)，閥座法蘭距地面高度宜為1.2m左右。
3. The dry alarm valve should be set in a safe and easy to operate place, and the height of the valve seat flange from the ground should be about 1.2m.
4、將干式報(bào)警閥安裝于管網(wǎng)系統(tǒng)之前，應(yīng)清洗供水管網(wǎng)，保證供水管網(wǎng)干凈、無(wú)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、閥蓋密封墊，檢查閥瓣動(dòng)作是否靈活。確認(rèn)動(dòng)作靈活后，裝好閥蓋密封墊和閥蓋。
5. Remove the valve cover and the sealing gasket of the valve cover, and check whether the action of the valve disc is flexible. After confirming that the action is flexible, install the bonnet gasket and bonnet.
6、將干式報(bào)警閥安裝在系統(tǒng)中，下端與供水管道相連，上端與系統(tǒng)噴淋管網(wǎng)相連。
6. Install the dry alarm valve in the system, with the lower end connected to the water supply pipeline and the upper end connected to the system spray pipe network.
注意：干式報(bào)警閥須直立安裝。建議干式報(bào)警閥兩側(cè)距墻不小于0.5m，正面距墻不小于1.5m，所有排水口均采取排水措施。更多注意事項(xiàng)額蓼的了解您可以隨時(shí)來(lái)網(wǎng)站

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 is not less than 0.5m, and the distance from the front side to the wall is not less than 1.5m. Drainage measures should be taken for all drains. For more information, you can come to the website at any time http://m.xintli.net consulting service
