雨淋喷水灭火系统的自动开启雨淋阀装置，可采用以下任何一种传动方式：带易熔锁封的钢索装置。其工作原理是，当易熔锁封受热熔解脱开后，传动阀自动开启、传动管排掉水，管网即降压，自动开启雨淋阀，但效果不太理想；带闭式喷头的充水或充气的传动管系统。该系统以闭式喷头作为感温探测器起探测火灾之用，传动管直径湿式为25毫米、干式为15毫米，当传动管系统中任意一个喷头开启喷水而引起传动管内水压降低时，都能自动打开雨淋阀，不过传动管必须高于雨淋阀；为了防止静水压对雨淋阀缓开的影响，湿式传动管的静水压不应超过雨淋阀前水压的1/4；带火灾探测器的电动控制装置。

“Automatically open the deluge valve device which gear”是由中国蝶阀网提供的阀门新闻，译文仅供参考。另外，中国蝶阀网还提供相关产品搜索：电动蝶阀、气动蝶阀、手动蝶阀、不锈钢蝶阀、对夹式蝶阀、衬氟蝶阀等。

译文：
Automatically open the deluge valve device which gear Rain sprinkler system automatically open the deluge valve device can be used in any of the following transmission mode: With fusible lock seal wire rope device. Its working principle is that, when the fusible lock seal by hot melt relief open, transmission valve automatically opens, transmission tube to drain the water pipe network, blood pressure, and automatically open the deluge valve, but the effect is less than ideal; Transmission pipe system with a closed nozzle water-filled or inflatable. The system closed nozzle as thermal detectors to detect fire from the use of the drive pipe diameter wet 25 mm, dry 15 mm, when the transmission pipe system of any one nozzle open sprinkler caused by water pressure to reduce transmission pipe can automatically open the deluge valve, but the drive pipe must be higher than the deluge valve; wet drive tube hydrostatic pressure should not exceed 1 of the deluge valve before the water pressure in order to prevent the influence of hydrostatic pressure to open the deluge valve relief / 4; With a fire detector electric control device.
