Alarm check valve of a fire extinguishing system, in particular, sprinkling or

Deluge and fire extinguishing system

The invention relates to an alarm check valve of a fire extinguishing system, in particular sprinkler or water spray, with 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. The invention further relates to such a fire extinguishing system with an alarm check valve, are connected to the one or more fluid conduits.

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 alarm valve stations of fire extinguishing systems, especially fire extinguishing systems using water-based extinguishing agents (eg. Water, water with additives, water mist in the low and high pressure region) , Prominent representative of this type of valve for fire extinguishing systems with water-based extinguishing agents are wet and dry pipe valves, and Deluge. In the field of fire extinguishing systems with gaseous extinguishing agents, the term alarm valve is unusual here is usually spoken by area valves or extinguishing control valves. As used in this protection law "alarm valve" also includes these types of valves.

According to the invention the fire extinguishing system valve and its immediate functional environment is understood as an alarm valve station. In addition to the fire extinguishing system valve are themselves all the elements, in particular components, shut-off devices, valves and lines which are not attributable to the extinguishing agent supply line and extinguishing agent discharge, but are cultivated for measurement, alarm, control, monitoring purposes, to the fire extinguishing system valve and arranged in the vicinity ,

Is understood to mean passive alarm valves is that they open automatically when exceeding a predetermined pressure differences between inlet and outlet sides, wherein an alarm is triggered in the control of the valves themselves in response to detecting this opening state, for example, indirectly by means of a arranged in an external alarm channel pressure switch an alarm means, such as an electrically powered alarm horn is over the then 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.

The inspection known firefighting equipment at regular intervals, for example every week, mostly by personnel of the fire extinguishing system operator. More particularly, the inspection of a fire extinguishing system comprising the verification of the alarm function and possibly reading of signals from sensors (such as pressures, fluid levels, temperatures) and / or checking whether the actuators of the fire extinguishing system can be operated as desired. The sensors can be as gauge, but also sensors that convert the physical signal into an electrical / electronic signal to mechanical sensors.

To check the alarm function of a fire extinguishing system, it has been necessary that a valve, such as a ball valve is opened manually to trigger a flood of one or more lines. In this way, triggering an erase operation is simulated, so that a check of the alarm function can be performed. When triggered, an erase operation, an alarm signal is usually sent to a fire detection and / or extinguishing control panel, so that when input of a

can be assumed that the alarm signal at the fire detection and / or extinguishing control panel that the alarm function of the fire extinguishing system is working properly. Subsequently, the valve is closed again, the fire alarm and / or extinguishing control panel reset and the fire extinguishing system thus again displaced a working condition. To check the alarm function of a fire extinguishing system, a high time and personnel expenditure is consequently necessary.

To read the readings of the sensors and / or checking whether actuator of a fire extinguishing system, the fire alarm broadcast / or extinguishing control panel will be as desired actuated normally read out or sent over this central control signals to the actuators, which is signal-conductively connected to the corresponding sensors and / or actuators , However, the fire detection and / or extinguishing control panel is located periodically, especially in complex firefighting equipment, in a separate room. The maintenance personnel, such as the Sprinklerwart, installer or service staff, thus checking the sensors and / or the triggering of the control signal to the actuators can perform not directly to the alarm valve of a fire extinguishing system. This increases the inspection task, especially in large systems considerably.

The same applies to the work incurred during maintenance, which are required by the manufacturer of the fire extinguishing system, for example, annually. The following describes the inspection and maintenance activities are grouped under the term maintenance.
