Problems solved by technology

[0004] However, there are cases where, due to space constraints or other reasons, the liquid container must be arranged in a position other than the vertical position
For example, the above solutions are not suitable for indicating the liquid volume of, for example, a substantially cylindrical liquid container arranged in a horizontal position

Embodiment Construction

[0015] figure 1 and figure 2 A fire extinguishing liquid container 1 of an embodiment of the present invention is presented. The extinguishing liquid container is substantially cylindrical with a substantially circular cross-sectional shape. exist figure 1 The middle fire extinguishing liquid container is arranged in a substantially horizontal position (in the horizontal direction), that is, on its side. The extinguishing fluid container has been filled with a certain volume of extinguishing fluid 5 , which has a surface level 4 . A part of the volume of the fire extinguishing liquid container 1 (the portion marked with reference number 6 ) does not contain fire extinguishing liquid but gas. The gas may be air or some other suitable gas, such as nitrogen. Gases can preferably be used in extinguishing fires together with extinguishing liquids.

[0016] The fire extinguishing liquid container 1 is, for example, a pressure container, and the plug member 10 is disposed in a...

Abstract

The invention discloses a method for monitoring the liquid quantity of a fire-extinguishing liquid container (1) of a fire-fighting equipment. The extinguishing liquid container (1) is filled with extinguishing liquid such that the predefined volume (6) remains unfilled, which is pressurized with gas to a standby pressure (P2) for example using a filling connector (2) , the standby pressure is higher than the switch point (Psw) of the pressure sensor or pressure switch (3), in this case, when the amount of the extinguishing liquid (5) in the extinguishing liquid container (1) decreases, the The pressure (P2) of the fire extinguishing liquid container (1) drops from the standby pressure (P2) with the expansion of the gas volume ratio, and in this case the pressure (P2) drop is caused by the amount of the fire extinguishing liquid and when the pressure drops from the reserve pressure to a second lower value set as the switching limit (Psw) of the pressure sensor or pressure switch (3), the pressure sensor or pressure switch (3) A switch (3) gives a signal from which notification is obtained that the liquid in the extinguishing medium container is low. The invention also relates to a device.

Description

technical field [0001] The invention generally relates to a fire-extinguishing installation in which a so-called hydraulic accumulator is used as a source of extinguishing medium, comprising at least one pressure vessel in which a liquid extinguishing medium can be stored, and the hydraulic accumulator The device can be connected to a source of pressure, more particularly to a container of pressurized gas, ie a gas cylinder. After the system has been activated by means of gas pressure, the liquid extinguishing medium or the mixture of liquid extinguishing medium and pressurized gas is led into the duct leading to one or more spray heads. Background technique [0002] For example in US Publication No. 5,632,337 some fire suppression systems including hydraulic pressure accumulators are proposed. [0003] The liquid of the liquid container may sometimes decrease in the liquid container, eg due to leaks or the like. In order to indicate the amount of liquid, various indicator...
