Definitions

  • the invention relates to a shaft equipped with fittings for water or steam lines, in particular for water meters.
  • the shafts, in which water meters are attached, are objects embedded in the ground below the frost line, with a removable cover, which have the task of being the necessary ones at the connection point of the line branching from the media-promoting main line to the consumer, generally a family house Fitting fittings such as valves, knee tubes, water consumption meter (“water meter”) etc. and to protect them from freezing.
  • the well-known water meter shafts mostly consist of concrete and may have a base plate. They are provided with a removable lid.
  • a shaft equipped with fittings is known from the Hungarian patent specification No. 1, in which the shaft element itself consists of plastic.
  • the arrangement of this shaft element and its fittings essentially corresponds to the description already given.
  • the patent also contains a proposal according to which the fittings in the interest of easier handling and better readability of the water meter should be placed more near the surface of the floor. In this case, however, a thick-walled shaft element and expensive thermal insulation must be provided. Nevertheless, the water meter will freeze if, for example, no water is drawn for 24 hours and the outside temperature is -5oC.
  • the aim of the invention is to eliminate the shortcomings described and to provide a shaft equipped with fittings for water or steam lines, with which the risk of freezing can be completely eliminated with relatively little effort and at the same time the fittings for the assembly and control of the floor surface are easily accessible from.
  • a shaft was assumed which, in a shaft element which is provided with a removable cover and is closed at the bottom, contains the fittings connected to the media-conveying line, for example supply and discharge pipes, valves, consumption meters, etc.
  • This shaft was further developed according to the invention in that the fittings installed between the outlet opening of the pipe leading in and the inlet opening of the pipe leading away are arranged in their basic position below the frost limit and are connected to a handle reaching up to the level of the ground, and further that the pipe entering and the leading pipe at least in part as flexible hose and / or are designed as an elastic tube, one end of which leads through the shaft element and the other end of which is connected by means of the handles which can be raised to floor level.
  • the incoming and outgoing pipe are formed from polyethylene heat-treated to the dimensional stability in the form of a pipe spiral. It is also advantageous if the two pipe spirals are arranged axially and fit into one another (similar to the threads of a two-speed screw), because in this case there is enough space in the interior of the pipe spiral for the fittings.
  • the shaft element is a suitably prefabricated element made of polyethylene, which has the shape of a cylindrical container.
  • the box element can be provided with a radial anchoring edge or ring.
  • Fig. 1 shows a vertical section through the shaft equipped with fittings
  • Fig. 2 shows the section along the line designated by II-II in Fig. 1.
  • the shaft element 1 of the water meter shaft according to the invention is sunk into the ground in such a way that its upper edge protrudes above the ground level.
  • the shaft element is 1 a cylindrical container made of polyethylene with a wall thickness of 5 mm, the jacket 2 of which is welded watertight to a base plate 3.
  • the upper part of the jacket 2 is closed by a removable, flanged cover 4, which is provided on both sides with a handle 5 and on the inner surface with an annular stiffener 6.
  • the cover 4 is also made of polyethylene in the present case, with a wall thickness of 7 mm.
  • the diameter of the shaft element 1 was chosen to be 500 mm and the height to be 1300 mm.
  • the base plate 3 continues in an annular edge 7, which improves the anchoring of the shaft element 1 in sandy soil, for example. If necessary, for example when the groundwater level is high, it is advisable to provide the shaft element 1 with a ring 8 which prevents it from floating.
  • the frost line is indicated with a thin line and provided with the reference number 9.
  • the frost limit is about 80 cm deep.
  • the following fittings are arranged in their basic position: the incoming pipe 10 connected to the media-conveying line, which is not particularly marked, the outgoing pipe 11 leading to the consumer (also not shown), and between them a knee pipe 12 or 13 on each side and with the interposition of a valve 14 a consumption knife constructed in a known manner (in the present case a water meter).
  • the pipe 10 leading in and the pipe 11 leading away are at least partially designed as a flexible hose and / or as an elastic, pressure-resistant pipe.
  • the incoming pipe 10 and away pipe 11 - apart from the end sections - are designed as coaxially fitted pipe spirals.
  • the tubes have a diameter of 25 mm and a wall thickness of 2.5 mm.
  • incoming pipe 10 and away pipe 11 are made of hard polyethylene.
  • the tubes are subjected to a shape-retaining heat treatment during manufacture, which is followed by a prolonged heat treatment at 120-150oC in water.
  • the lower end of the pipe 10 leading in and the pipe 11 leading away are led to the outside through bores 18 and 19 made in the casing of the shaft element 1 and fastened by means of a waterproof welded bond (see FIG. 2).
  • the upper end of the pipe 10 leading in and the pipe 11 leading away are connected to the consumption meter 15 from both sides via the pipe elbow 12, the valve 14 and the pipe elbow 13 in the manner shown in FIG. 1.
  • the valve 14 installed in the incoming pipe 10 can be any known closing valve, but the valve installed in the outgoing pipe 11 is expediently a one-way flow check valve.
  • the pipe bend 12 is with the outlet opening of the pipe 10 entering with the inlet opening of the pipe 11 leading away by a welded connection, but connected to the valves 14 by a screwed connection.
  • the elbows 13 are connected to the valves 14 or to the connecting piece of the consumption meter 15 in the usual way by screw connections.
  • the pipe elbows 12 and 13 are also made of polyethylene in the present case.
  • the fittings can be raised from their basic position indicated by a solid line to floor level, for example by means of the handle 16 attached to the pipe elbows 12.
  • the fittings can be lifted, for example, when reading the consumption meter 15 or when Installation of fittings, their inspection or repair may be necessary.
  • the upper ends of the incoming pipe 10 and the away pipe 11 follow the movement of the fittings, i.e. in the present case there is an elastic deformation of the tube spirals, they are pulled apart in the vertical direction.

Abstract

Un puits à robinetteries pour conduites d'eau ou de vapeur, en particulier pour compteurs d'eau, contient dans un élément de puits pourvu d'un couvercle amovible des robinetteries reliées à des conduites d'eau ou de vapeur, telles que des soupapes, des conduites d'admission ou d'évacuation, des tuyaux coudés, des compteurs d'eau ou de gaz. Dans leur position normale, les robinetteries (12, 13, 14, 15) montées entre l'orifice de sortie du tuyau d'amenée (10) et l'orifice d'admission du tuyau d'évacuation (11) sont agencées dans la partie inférieure de l'élément de puits (1), au-dessous de la ligne de gel (9), et reliées à une poignée (16) qui s'étend jusqu'à la surface du sol. Les tuyaux d'amenée et d'évacuation (10 resp. 11) sont, au moins en partie, des tuyaux flexibles ou des conduites élastiques, de préférence enroulés en spirale; une de leurs extrémités traverse l'élément de puits (1) et l'autre est reliée aux robinetteries (12-15), qui peuvent ainsi être soulevées près de la surface à l'aide de la poignée (16).
