Embodiment Construction

[0023] The invention is described by way of illustrative examples illustrating the basic principles.

[0024] figure 1 is a schematic diagram showing an example of a hose test pressurization device according to a first illustrative design. The test pressurization device itself may be arranged in association with a hose cleaning unit, followed by drying and / or winding of the hose and possibly other associated functional units. However, the following description is mainly directed to the test pressurization device.

[0025] Typically, the test pressurization device 100 is adapted to receive a hose such as a fire hose. The device is also generally suitable for supporting hoses under both pressurized and non-pressurized conditions. The test pressurization device essentially comprises a first pair of pressing rollers 10 , 12 between which a hose can be inserted, wherein the first pair of pressing rollers 10 , 12 is arranged at a distance from the second pair of pressing rollers ...

Abstract

A test pressurization device (100) for hose (1) includes a first pair of press / driving rolls (10, 12) between which the hose can be inserted, and a second pair of press / driving rolls (20, 22) between which the hose can be inserted. The first pair of press / driving rolls (10, 12) is arranged on a distance from the second pair of press / driving rolls (20, 22). Further each pair of press / driving rolls is arranged for pressing the hose together between the rolls in conjunction with pressurization with a medium such as water so that a limited part of the hose, which is located between the first and the second pair of press / driving rolls, can be held pressurized and control of the hoses or its couplings tightness is admitted. Furthermore, while sections of the hose are held pressurized between the pairs of press / driving rolls, the same pairs of press / driving rolls are feeding the hose forward, thus checking the hoses tightness in a continuously moving section approach. In this way a very space efficient solution is achieved, as only a limited part of the hose needs to be held pressurized at a time.

Description

technical field [0001] The invention relates to a test pressurization device for a hose and a test pressurization system comprising such a test pressurization device. Background technique [0002] Hoses, such as fire hoses, are often inspected after use in order to additionally control hose tightness. This is usually done by connecting one end of the hose to a so-called air valve and the other end to a liquid pump (usually a water pump) that fills the hose with a pressurized fluid such as water. The air inside the hose then escapes through the air valve that allows the passage of air and gas but not water. [0003] Typically, the hose is wound in the form of a screw thread on a drum with a preferably vertically oriented axis, so that the winding can take place in a relatively small space. The entire coiled hose is filled with pressurized fluid, and the fluid-filled hose can then be inspected. [0004] During pressurization, the hose may burst, at which point the operator ...
