Field of application of the invention

The egg / indung relates to a valve assembly for sorted in extinguishing areas extinguishing systems, which is used to control the extinguishing agent flow.

Characteristic of the "known state" of technology

Large fire areas Industrial and public buildings, equipped with automatic extinguishing systems, are fitted with nozzles that work together in individual extinguishing sections, provided that no single spray nozzles are triggered. Each extinguishing section is equipped with one or more fire detectors, which put the respective extinguishing section into operation during a fire. When used as intended, each extinguishing section will only start operating when it is already burning.

After a fire has broken out, there is the danger that heat radiation, flying sparks, overturning shelves o. Ä. A neighboring section is ignited. This type of fire spread can not be prevented with the known solutions.

It is known to arrange for preventive protection against the spread of fire part of the spray nozzles of a deletion section so that they spray the neighboring sections partially. The disadvantage of this solution is that the water damage in the neighboring sections can be very large, while the preventive fire protection is limited to a relatively narrow range of neighboring sections, the z. B. can be bridged by overturning shelves. As a result, the safety 'jegen a spread of the fire is not guaranteed.

Ziei the invention

The aim of the invention is to provide a valve assembly for subdivided in extinguishing sections extinguishing systems that keeps the damage from the fire and the extinguishing agent use as low as possible.

Explanation of the essence of the invention

The invention has for its object to develop a fitting assembly for subdivided in extinguishing sections extinguishing systems, which in case of fire by a each extinguishing area associated with triggering unit, z. B. from fire alarm hose and a pressure-closing diaphragm valve is actuated and confined the fire safely on the triggering extinguishing section and fought in this extinguishing section. The moisture penetration of the adjacent sections should be as low as possible. According to the invention this object has been achieved in that each extinguishing section is associated with a control valve and a pressure-opening diaphragm valve. The diaphragm valve of the trip unit is arranged between the main water line and a hydraulic-mechanical switching element of the control valve.

This control valve consists of the hydraulic-mechanical Umschaltelement and at least two of the hydraulic-mechanical switching element downstream, parallel-connected control valve chambers. Each of the control valve chambers is associated with at least one extinguishing section, with the pressure-opening diaphragm valve, the control valve chamber is linked via a hydraulic control connection.

Advantageously, each control armature chamber is also linked via a hydraulic control connection to the pressure-opening diaphragm valve of its own extinguishing section.

The fitting assembly according to the invention serves to control the fire extinguishing system. In contrast to the known ones Solutions not only the triggering section is put into operation with the fitting arrangement according to the invention, but

also the adjacent extinguishing sections operated.

The fitting arrangement according to the invention ensures that the neighboring sections despite intervals Keep their full sensitivity and functionality. The extinguishing sections adjacent to the burning section WeTC ¹ Jn operated one after the other for a certain period of time. This will cause the adjacent erase sections in

sprayed at regular intervals and are dime safe from fire spread, without very high

Requirements for the capacity of the water supply. If each of the control valve chambers is linked to the pressure-opening membrane valve of its own section, then takes place

the triggering of the burning section will cause this valve. Thus, the pressure-closing diaphragm valve only serves to release the control water flow. It is a very compact design of the fitting arrangement possible.

Due to the interval triggering of the adjacent erase sections is sufficient that false tripping z. B. by Temperature jams are avoided. This additional effect becomes meaningful in that false triggering of Fire-extinguishing systems often cause considerable economic damage. Another additional distribution is that there is no need to provide additional help for the controller. That increases

on the one hand, the functional reliability dor extinguishing system and also makes the saving for the safe provision of

Power supply, z. As electric power, necessary funds possible. If a fire breaks out in a fire extinguisher section, the fire alarm hose will burst, closed under pressure Diaphragm valve will open. As a result, the control valve of the burning section is supplied with water. By the

Hydraulic-mechanical switching element are in a fixed order in the control valve chambers with water. During the filling time of this Steuerarmaturkammer all the pressure-opening diaphragm valves with

Pressurized pressure associated with this Steuerarmaturkammer. In the extinguishing sections, where these are under pressure

So are the fire extinguishing system for the time taken in operation, which is required for filling the associated Steuerarmatui chamber.

If the control valve chamber is filled, the hydraulic-mechanical switching element acts on the next one Control fitting chamber, whereby the extinguishing sections associated with this control valve chamber are triggered. Ausführungsheltplel

To further explain dos essence of the invention, a fitting assembly for a divided into four sections fire extinguishing system will be described below

 The accompanying drawings show:

Drawing 1: Schematic diagram of a deletion section associated fittings Fig. 2: schematic representation of the operating time of the extinguishing sections as a function of the triggering soktion Drawing 3: schematic representation of the combination of the deletion sections Drawing 4: Schematic diagram of a second embodiment of a deletion section associated fittings

About a main water line 1, the water supply of the extinguishing system. From this main water line 1 branch off the extinguishing water line 2 of the extinguishing section.

In addition, the Wasserzuiührung to one of the extinguishing sections associated control valve 3 via a water pipe 4 in which a pressure-closing diaphragm valve 5 is installed. In the control valve, the water is distributed by a hydraulic-mechanical switching 3.1 successively to at least two control valve chambers 3.2. By control lines β, a pressure-opening diaphragm valve 7 in the burning extinguishing section and the pressure-opening diaphragm valves 7 of the control valve chamber 3.2 associated extinguishing sections are acted upon by the water pressure and trigger these extinguishing sections for a short period of time.

Check valves 8 prevent influencing the control valve 3 at interval triggering by one of the neighboring sections.

Fig. 2 illustrates the switching cycle of a subdivided into four extinguishing sections extinguishing system of the sections A and D fire case mutually the two adjacent erase sections B and C are triggered. If Section B is burning, then other extinguishing sections should be sprayed one after the other one by one. If there is a fire in section C, then sections A and D are sprayed simultaneously and section B is put into operation individually for the double period. The Schschschema this fire extinguishing system is shown in Fig. 3.

The circuits are achieved by different numbers of control armatures 3.2, by different assignments of extinguishing sections to these control armatures 3.2 and by different volumes of Steuerarrnaturkammern 3.2.

4 is the schematic diagram of a second embodiment of the valves associated with a deletion section. It differs from the valve arrangement shown in Fig. 1, that the water supply to the extinguishing section via two parallel fire extinguishing water lines 2.1 and 2.2 can be done. The fire extinguishing water 2.1 is used in a fire in the extinguishing section and the extinguishing blade 2.2 for interval operation of the extinguishing section, triggered by a neighboring section used.

The second difference is that the control lines 6 are clearly direction-oriented. Therefore, in this embodiment, two control lines β must lie between two extinguishing sections, if they are to trigger each other in the event of a fire as neighboring sections.
