  • The Invention relates to housing for water consumption meters, comprising a feed and a discharge nozzle for watertight, removable installation in suitable end pieces of Water pipes.
  • Of the Installation of water meters, especially house water meters, is subject to legal regulations and Europe-wide standards. So is the water meter not only frost-free, but also to arrange so that he is possible fast, carefully and read smoothly and replaced at the end of the calibration certificate can be. water meter have to Furthermore, be installed so that the water pipe when replacing of the meter can yield at least 3 to 4 mm at the place of installation. In addition, the water meter be installed stress-free, d. H. the water meter components are so too secure that with built-in and removed water meter the occurring personnel be recorded.
  • to Realization of this requirement, DIN 1988 recommends the use a stable, U-shaped Mounting bracket. On whose legs are a length compensation fitting and a meter fitting intended. These two valve parts carry screw threads and / or union nuts and are with suitable sealing surfaces Mistake. The mounting bracket is between the connecting lead and the consumption of the Water supply line firmly mounted, the fitting parts are connected to the cable ends. Subsequently, the water meter whose Housing one Inlet and one outlet socket each has a screw thread, with the help of union nuts solvable attached.
  • At the The installer must assemble and disassemble the water consumption meter with two wrenches handle. With one wrench he holds the water meter, with opens to the other or closes he the union nut. It happens again and again that parts are damaged. Depending on which length dimensions The new water meter has to be replaced every time Längenausgleichsverschraubung be adjusted. This is time consuming and increases assembly costs.
  • The The fact that the water meters are screwed in does not increase only the assembly times, but also increases the production costs by cutting the threads on the connecting pieces.
  • Of the The present invention is therefore based on the object, a housing for a water meter specify the type mentioned, which are easy to produce lets and that can be easily and quickly assembled and disassembled.
  • These Task is solved through a water meter housing with the features of claim 1.
  • The The present invention replaces the current cumbersome one Screw mounting by a simple and quick plug-in installation. At least one of the housing stubs, preferably, of course both, is preferably a smooth cylinder, at least in some areas designed as a circular cylinder. For mounting the sockets are in matching tails plugged in the connecting cable or the power line. The Sealing is advantageously carried out by an O-ring on sits the circular cylinder. Also, the counter can still after mounting around ± 90 ° around his longitudinal axis be rotated to improve readability without having to Tools needed become.
  • Becomes the one housing neck inserted into a corresponding receptacle, it is compulsory between the other housing socket and its counterpart a gap, which must be sealed watertight. This is done with help a sliding sleeve, which according to a preferred embodiment of the invention on the housing neck of the water consumption meter sitting. This ensures that when replacing the water consumption meter respectively a brand new sliding sleeve is used.
  • alternative can the sliding sleeve on an end piece of the connection or consumption line to sit.
  • Around to prevent the sliding sleeve from shifting during use, it cooperates with a positive locking element. As such, for example, a bayonet closure into consideration. An alternative embodiment is a safety clip behind the sleeve on the through the Move vacant space set on the circular cylinder becomes.
  • In the case, that a water meter, its housing is still equipped with screw threaded connection, with a water supply line should be connected, already for the inventive plug-in assembly pre-equipped is, lets the smooth invention and at least partially circular cylindrical connecting pieces Screw on the screw threaded connection.
  • In the case, that equipped with a smooth cylinder nozzle according to the invention water consumption meter in a conventional, still with union nuts equipped Attachment to be used are two adapters with matching end pieces and optionally bolted to a sliding sleeve, which is the connection with the water consumption meter cause.
  • ever after housing shape let the nozzle according to the invention also in the case insulate.
  • It is understood that the production of a smooth and cylindrical, especially circular cylindrical neck is much easier as the preparation of a nozzle with cut thread. Becomes the housing made of plastic, the advantage results from the use considerably simpler injection molds.
  • advantageously, Both nozzles are partially designed as a circular cylinder, wherein the two circular cylinders are aligned. This makes it possible for the mounted water meter without tools around its longitudinal axis to pivot to facilitate the reading.
  • If in the outlet nozzle a backflow preventer is used, which must be checked without removal, before and behind this one each with a shut-off equipped Prüfstutzen intended. One of the test sockets is part of the sliding sleeve. The housing side test connector can also be used as a deaerator serve.
  • Based the drawing is intended to illustrate the invention in the form of embodiments be explained in more detail. They each show purely schematically
  • 1 a first embodiment of a half housing for a water consumption meter,
  • 2 a second embodiment of a half housing for a water consumption meter,
  • 3 a housing of a water consumption meter in a first installation situation and
  • 4 a housing of a water consumption meter in a second installation situation.
  • 1 shows purely schematically a housing 1 a water consumption meter, of which only one housing half is shown. At the housing 1 you can see an inlet or outlet nozzle 2 , This is over the greater part of its length as a smooth cylinder 3 shaped with hexagonal cross-section. The free end of the neck 2 is as a circular cylinder 4 educated. Although it would not be necessary for the inventive plug-in assembly of the water meter housing, it has been found to be advantageous in terms of permanent sealing, the sealing point as a circular cylinder 4 train.
  • 2 shows an alternative embodiment. Here is the entire neck 2 as a circular cylinder 4 educated. He also wears an O-ring 5 as a sealing ring.
  • 3 shows a meter housing 1 in the installation situation. The left, as a circular cylinder 4 trained neck 2 is with his O-ring 5 in a circular cylindrical opening of a connecting line or connection fitting 11 plugged in. By more or less deep insertion length compensation is possible.
  • The right, also as a circular cylinder 4 trained neck 2 is factory with a sliding sleeve 6 equipped, which was pushed to the right and so the gap between the connecting piece 2 and the matching counterpart 12 the consumption line bypasses. This gap necessarily arises when inserting the left neck 2 into the connecting line or fitting 11 ,
  • To prevent the sliding sleeve 6 intentionally or unintentionally can be pushed back, is a locking element in the form of a safety clamp 7 intended. This sits on the by moving the sleeve 6 vacated space on the circular cylinder 4 of the connecting piece 2 and thus blocks the sliding sleeve 6 ,
