Problems solved by technology

However, since the pre-action system needs to be filled with low-pressure gas in the pipe network to monitor the tightness of the pipe network and whether there is any misoperation of the nozzle, most of the pre-action systems currently on the market need to superimpose a check valve on the valve block to prevent When inflating, the gas leaks from the normally open alarm port of the lower valve group, but this method has the disadvantages of high cost, complex structure, and inconvenient installation for the production process and users.

Embodiment Construction

[0031] The present invention will be further described below in conjunction with the accompanying drawings:

[0032] like Figure 1-Figure 4 As shown, this embodiment provides an automatic sprinkler system, including a sprinkler system, a pre-action system and a water supply system, and the pre-action system includes a diaphragm valve 1, a diaphragm control device 2, a hydraulic alarm device 3 and a diaphragm cavity compensation valve 4 , the diaphragm valve 1 is provided with a main water supply side channel 11 that communicates with the water supply system, a system side channel 12 that communicates with the spray system, and a diaphragm chamber 13. The diaphragm control device 2 is connected to the diaphragm chamber 13. The diaphragm control device 2 changes through the water pressure The communication and closing of the main water supply side channel 11 and the system side channel 12 are controlled by changing the position of the diaphragm chamber 13 .

Abstract

The invention relates to an automatic water spraying fire extinguishing system which comprises a spraying system, a pre-acting system and a water supply system, the pre-acting system comprises a diaphragm valve, a diaphragm control device, a hydraulic alarm device and a diaphragm cavity compensation valve, and a main water supply side channel communicated with the water supply system, a system side channel communicated with the spraying system and a diaphragm cavity are arranged in the diaphragm valve; the diaphragm control device is communicated with the diaphragm cavity, the diaphragm cavity compensation valve comprises a compensation valve body, a compensation valve element, a compensation valve diaphragm piece and a valve element cleaning device, and the interior of the compensation valve body is divided by the compensation valve element and the compensation valve diaphragm piece to form a water supply side connector channel, a diaphragm cavity connector channel and an alarm connector channel. A compensation channel communicated with the water supply side connector channel and the diaphragm cavity connector channel is arranged in the compensation valve element, the water supply side connector channel is connected with the main water supply side channel, the diaphragm cavity connector channel is connected with the diaphragm cavity, the alarm connector channel is communicated with the hydraulic alarm device, and the valve element cleaning device moves along the compensation channel.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing, in particular to an automatic sprinkler fire extinguishing system. Background technique [0002] The pre-action system is a closed system in the automatic sprinkler system. Through the effective combination with the automatic fire alarm control system, it can effectively protect the protection area. Compared with the specific wet system, it has the advantages of anti-freezing and preventing accidental spray. , Compared with the dry system, it has the advantages of fast response and so on. It is widely used in cold storage, computer room, electronic factory, archives and other places where it is easy to freeze and does not allow accidental spraying. However, since the pre-action system needs to be filled with low-pressure gas in the pipe network to monitor the tightness of the pipe network and whether there is a malfunction of the nozzle, most of the pre-action systems on the market cur...
