DE2623644A1 - Fire hydrant testing attachment - uses connecting piece with press. gauge and rain cock and includes reducing nipple - Google Patents

Abstract

The design concerns a device for testing a wall mounted fire hydrant for operational fitness. The traditional method of performing the test with the hoss on and trailing them out int the open for discharging the water during the test is cumbersome. The device consists of a two-part piece of pipe (1, 11) with one end having a union coupling (2) to attach the device to the hydrant outlet connection. The pipe stub (1) is connected to pipe (11) by union (3) and the bend end of this pipe is connected to a smaller pipe (6) by reducing a nipple. The smaller pipe has a gauge (5), a drain cock (7) and draining hose (8).

Device for functional testing of stationary Fire service hydrants, especially wall hydrants

The invention relates to a device for functional testing of stationary fire service hydrants, especially wall hydrants.

Fire service hydrants must be checked to ensure that they are working properly at the prescribed intervals. Especially with Checking wall hydrants in office buildings can be associated with unpleasant side effects. The ones from the hydrants Fire hoses laid outdoors, often over several floors, can be significant as a result of any leaks Cause damage from leaking water. In addition, the fire hoses must be returned after each check dismantled and dried so that they can be stored at the designated storage locations. All this· Circumstances contribute to the fact that checking is not carried out regularly in the factories, so that difficulties arise in an emergency may occur.

The object of the invention is to be connected to the hydrant by a Facility to facilitate functional testing.

This task is carried out by a hydrant that can be connected to the fire brigade Test socket loosened with pressure gauge.

As a result, the entire test process can be carried out on the spot in a few minutes, without the need for a fire hose must be relocated. The test socket is connected directly to the hydrant. Then the hydrant slide opened and the pressure can be read on the manometer. After the check has been carried out, the hydrant slide is again closed.

In order to also be able to check hydrants that are housed in niches, the test socket can have a swivel joint. This The swivel joint preferably consists of a conical part that can be locked with a screw connection. After loosening the screw connection the cone part and thus the test socket can be attached to the hydrant slide be adapted, depending on whether this is arranged on the right or left in the vanity box.

Finally, the test socket can have a water drain.

This means that after the check has been carried out, the test socket under Pressurized water, for example, drained into an egg that you carried with you. For this purpose, it is expedient to use the end of the test socket a piece of hose is provided. As soon as the water has been emptied from the test socket, it can be removed from the hydrant again be solved.

The invention is to be explained in more detail on the basis of an exemplary embodiment will.

The Fij. shows a view of a test socket.

The test socket consists of a two-part pipe section 1, 1 '. One pipe section 1 has a coupling 2 at one end for coupling to the hydrant and is by means of a conical screw connection 3 connected to the other pipe section 1 '. To As long as the screw connection is in place, the pipe section 1 'can be adjusted from the straight line by a certain angle. This is special advantageous for wall hydrants.

The other end of the pipe section 1 'is provided with an arc A, on which a Robr provided with a manometer 5 is located adjoins, at the end of which a through valve 7 is connected, which is connected to a piece of hose 8.

After coupling the test socket to the hydrant and with the through valve 7 closed, the hydrant slide can be opened will. The pressure gauge 5 shows whether the prescribed water pressure is available. Then the hydrant slide closed again and the water in the test socket by opening the valve 7 via the hose section 8 drained into a bucket.
