Definitions
- the invention relates to a fitting for pipes used in a geothermal probe device.
- a geothermal probe collects heat from the earth. Its operating principle is based on the fact that the temperature of the soil increases as a function of its depth.
- a geothermal probe device essentially consists of a probe head which is available at the bottom of a borehole and of a system of pipes making it possible to convey a liquid to the probe head and to recover it at a temperature superior, this thanks to the heat exchange occurring between the ground and the moving liquid.
- the pipe system has at least two pipes. However, it can consist of a higher number of pipes. For example, it is possible to provide two lines for conveying the liquid to the probe head and one or two lines for recovering the liquid. In the case where there are two supply lines and a recovery line, the probe head is configured so that the two supply lines join to form a recovery line.
- fittings are used which can for example have the shape of a Y if it is a question of grouping two pipes in one.
- European patent application EP 1 036 974 A1 describes a Y-shaped connector which can be used both as a grouping element for two pipes or as a probe head. For this second application, one end of the Y is closed by a plug.
- the object of the present invention is to provide a robust fitting which is easy to manufacture and therefore economical, which can be used as a grouping element for several pipes or as a probe head.
- a connector for pipes used in a geothermal probe device characterized in that it consists of a block of thermoplastic material comprising a first flat face and in which is disposed at at least a first machined passage, the two ends of which open on said first flat face, each of said ends being dimensioned so as to receive and fix by welding respectively the end of a first and of a second pipe.
- the passage is machined, for example by means of bits, from a block of thermoplastic material such as polyethylene.
- the fitting according to the invention is more robust than the fittings of the prior art due to the fact that it consists of a block, therefore not having fragile parts, eg branches, like the fitting described in
- the connector forms a geothermal probe head.
- the ends of the passage preferably open on the upper face of the block, thus making it possible to position the ends in the extension of the pipes which come to be fixed there.
- the probe head comprises a second machined passage, the two ends of which also open on said first flat face, each of said ends of the second passage being dimensioned to receive and fix by welding respectively the end of a third and a fourth pipe.
- two delivery pipes and two recovery pipes are preferably used.
- the two passages are separated and according to another variant the two passages communicate with each other. In the latter case, the communication area is preferably enlarged to form a cavity.
- the probe head can be connected to an odd and / or higher number of pipes.
- the connector is used to group pipes of the same functionality into a smaller number of pipes, for example to reduce two recovery pipes into one pipe.
- This grouping of pipes offering the possibility of reducing the number of pipes ending in or leaving a heating plant.
- the connector has a second passage, the first end of which opens on a second face of the block which is opposite to said first planar face, said first end of the second passage being dimensioned to receive and fix by welding.
- the end of a third pipe the two passages communicating with each other via the second end of the second passage.
- the section of the first end of the second passage is greater than the section of the ends of the first passage.
- the section of the first end of the second passage is substantially equal to the sum of the sections of the ends of the first passage.
- Figure 1 illustrates a probe head
- Figure 2 shows a cross section of the probe head of Figure 1
- Figure 3 illustrates a grouping fitting of two pipes
- Figure 4 shows a cross section of the fitting of Figure 3
- Figures 1 and 2 show a probe head 1 consisting of a block, for example of polyethylene.
- the upper part of the probe head 1 has a cylindrical wall 8, the lower part is frustoconical.
- the upper face 20 is flat and has four holes 3-6.
- the interior of the head 1 comprises a cavity 7 connected to the four orifices 3-6.
- the height of the probe head 1 can be 10 cm, its diameter 10 cm and the diameter of the orifices 3 cm.
- Figure 2 shows two pipes 9,10 which are fixed to the probe head 1.
- the external wall of the end of each pipe 9,10 being fixed by welding on the internal wall of an orifice 3,4,5 or 6.
- the welding of the pipes 9, 10 with the probe head can be carried out using a technique known to those skilled in the art.
- the attachment zone can for example be defined to a depth of 3 cm in the probe head 1.
- Figures 3 and 4 show a grouping connection of two pipes. It consists of a block 2 formed of planar faces.
- the upper face 21 has two orifices 13,14 and the lower face 22 has an orifice 15, the three orifices 13-15 being placed in communication 16 inside the connector 2.
- the height of the connector can be approximately 8 cm , the diameter of the upper holes of 2.5 cm and that of the lower hole of 3.2 cm.
- the diameter of the upper holes can also be 3.2 cm and that of the lower hole 4 cm.
