Sprinkler valves and fire extinguishing systems with selfsame

The present invention relates to a fire extinguishing system valve comprising a housing having a fluid inlet chamber, a fluid outlet chamber and a closing body to switch between a locking state and a release state and forth movable, wherein the fluid inlet chamber and the fluid outlet chamber are separated from one another in the blocking state and communicate with each other in the release state a fluid-conducting.

Under Sprinkler valves of the present invention will be understood the genus both passive and active alarm valves in the sense that are designed for use in fire extinguishing systems, especially fire extinguishing systems using water-based extinguishing agents (eg. Water, water with additives). Prominent representative of this type of valve are wet and dry pipe valves, and Deluge. Here we mean by passive alarm valves that automatically open upon exceeding a predetermined pressure differences between inlet and outlet side, even an alarm is triggered by the valves in response to detecting this opening state, for example, indirectly by means of a arranged in an external alarm line pressure switch, via the then an alarm means, such as an electrically powered alarm horn is controlled and / or hydraulically operated directly by controlling the extinguishing medium flow to a fluidly connected to the alarm valve alarm means such as a water-powered alarm. Partial optical displays in the field of alarm valves are arranged to be able to distinguish parallel-arranged pipe valves better in a variety well instead of or in addition to hydraulically operated alarm bells, which has been opened, the alarm valves.

Among active alarm valves will be appreciated that the valves according to an input of a fire signal from external fire detection means, or as a function of external control intervention, active release the fluid flow through the valve is opened and an alarm is triggered as for the passive alarm valves. The above-mentioned valve types have in common that they are often installed in fire extinguishing systems for long periods without having to be used, and it is important that the valves in an emergency function reliably. Thus, a regular review of the functioning of the valves is essential.

In the prior art it is known to attach external piping in the field of pipe valves and piping to these devices for measuring pressure, including pressure gauges and / or pressure switch. Here, for example, about the pressure in the fluid inlet chamber can be detected. It is also known to install facilities, even in the absence of fire to open for a short time with the alarm valve to periodically check the valves operate in a predetermined manner.

In the low pressure area of ​​traditional sprinkler and deluge systems to about 25 bar external piping are often made using threaded fittings according to the prior art, partly also on site. The expense of providing, assembling, visually appealing, and aligning the fluid and pressure-tight connecting the external components arranged is significant. Externally mounted components require appropriate space in the main room. And finally there is in externally arranged tubing is a risk that this will be damaged during transport to the installation site, if they are already installed at the factory manufacturer.

According to the prior art must at alarm valves with electrically powered alarm means or displaying an electrical connection be established between arranged near the alarm valve electrical pressure switches and a normally remote fire detection or monitoring center and arranged back from the fire detection or monitoring center to near the alarm valve electrical alarm means or to the display. Such electrical connections between each other are arranged spatially separated elements can particularly easily be interrupted for longer distances and are therefore in fire extinguishing systems, a security risk.

By the electronic evaluation unit 50 or the data processing unit 20, the print data thus obtained are processed, in particular compared with predetermined limit values. Deviations from a desired pressure curve or overruns or underruns the predetermined limit values ​​are recorded, for example in the data memory 16 of the fire extinguishing system valves or a (not shown) data memory of the data processing unit 20. For example, if the pressure in the fluid inlet chamber drops, although the closing body than in the locking position located reported is, the data processing unit is preferably adapted to output a corresponding error signal. For example, if the pressure in the - in the standby state standing under atmospheric pressure - alarm channel increases by opening of the alarm valve, the data processing unit is preferably adapted to issue a corresponding alarm signal.

For example, if the pressure in the fluid outlet chamber below a certain threshold falls include startup of the sprinkler heads, should open below which the closing body, but in spite of the message of the valve, that the closing body is in the release position, sets no change in pressure in the fluid inlet region, the set data processing unit preferably to output also for this purpose a corresponding signal for the suspected disorder.

Similarly, the occurrence of leaks or other malfunctions in the distance is detected by means of the ongoing pressure monitoring inside the fire-fighting system valve. Manual maintenance work can be started purposefully. This is even more, although its location and design are transmitted with the status information of the fire extinguishing system valve and when a plain text display is available. This simplifies the training of maintenance personnel immense.
