    thus typically an operator, must put his hand in the space.
    The invention furthermore relates to such a sampler 1 where the conductor 4 comprises a controllable valve 5 which is controlled by a device so that only when the side opening 7 is closed can the valve be opened. This provides additional safety when sampling.
    Brief description of the figures Fig. 1 shows a cross section through the sampler with connecting pipe sections and collecting funnel Fig. 2 shows in greater detail a cross section through the sampler with collecting funnel Fig. 3 shows part of the sampler seen from the side Figs. Fig. 4 shows a first step in sampling with the sampler in partial cross-section seen from above. Fig. 5 shows a second step in sampling with the sampler. Fig. 6 shows a third step in sampling with the sampler. Fig. 7 shows a fourth step in sampling with the sampler. preferred form of expression F íg. 1 shows a cross section through the sampler 1 with connecting pipe sections 2 and collecting funnel 3.
    Liquid which can be hot, corrosive or toxic flows through the main pipeline 2 and with the sampler samples can be taken from the main pipeline in a safe and reliable manner. From the main pipeline, part of the fate is diverted through a conductor 4 to the sampler and this fate can be controlled with a sampling valve 5 which opens or closes the fate through the conductor. The conductor extends from the main pipeline and opens into the upper part of the sampler so that the liquid that fl ejects from the mouth of the conductor is directed downwards.
    The sampler comprises a substantially cylindrical enclosure 6 which forms the wall of the sampler. In the wall of the sampler there is a door opening 7 through which a sample can holder 8 with associated sample can 9 can be passed. With the sample can holder in the position illustrated in the figure, the sample can is located directly below the mouth of the conductor so that liquid from the conductor flows down into the sample can.
    The sampler is provided with a substantially flat, circular roof 10 which closes the sampler upwards and is watertight. Extending through the center of the roof is the mouth part of the conductor and offset from the center of the roof a rinsing water nozzle 11 is arranged from which rinsing water can be sprayed out into the interior of the sampler. The rinsing water nozzle is arranged so that it sprays a wide jet that covers large parts of the sampler's interior and inner walls.
    The bottom of the sampler is open so that any spills from the conductor and rinsing water from the rinsing water nozzle can drain downwards. To collect liquid flowing out through the bottom of the sampler, a hopper 3 is arranged at the bottom of the sampler. The funnel extends over the bottom of the sampler around its periphery so that all liquid collects in the funnel, even if smaller amounts would splash obliquely upwards. The funnel is conical with a plane fl even around its upper limiting surface and this fl is attached to a lower fastening ring 12 on the sampler. The lower fastening ring extends around the periphery of the sampler and is arranged a distance above the lower edge of the sampler. The roof of the sampler also extends outside the cylindrical enclosure and between the projecting portion of the roof and the lower fastening ring extends a rotatable shaft 13 to which the sample can holder 8 is connected. A guide ring 14 is also connected to the sample can holder and the shaft, by means of which the sample can holder can be turned into the sampler and out of it via the door opening 7.
    This is described in greater detail in connection with fi g. 4-7.
    Fig. 2 shows in greater detail a cross section through the sampler with collecting funnel, while the main pipeline is not covered by the uren clock.
    Fig. 3 shows part of the sampler seen from the side, with the sampler turned so that the door opening is illustrated straight to the right in the figure. The sample can holder and all details arranged outside the cylindrical enclosure 6 have been eliminated in the för gure for clarity.
    Figs. 4-7 show the sampler in partial cross-section seen from above in a first to fourth step when sampling with the sampler. The conductor 4 illustrates the conductor 4 and the bushing 15 in the ceiling where the rinsing water nozzle 11 is arranged. Connected to the control arm 14 is a door 16 which forms part of a cylinder surface and covers the door opening. The door can suitably be transparent so that the sampler can see what is happening inside the sampler. In the closed position, the door can be locked in position with an eccentric lock 17 which presses the side of the door facing farthest from the guide arm towards the cylindrical enclosure 6 which forms the wall of the sampler and sealingly closes the door opening.
    The eccentric lock is illustrated only in fi g. 4.
    In Figure 4, the sampler is closed with the empty sample can holder 8 inside the sampler and the door closes the door opening. I fi g. 5, the empty sample can holder has been turned out of the sampler and with this the door has been opened because the sample can holder and the door are mechanically connected to each other. I fi g. 6, the sample can holder has been provided with a sample can, the sampler has been sealed and a sample has been taken which fills the sample can. This is illustrated by the dashed portion in the interior of the sample can holder. I fi g. 7, the sample can holder has been unscrewed from the interior of the sampler and the filled sample can is now available for removal. The figures show the important point of the sampler's design, which thus simultaneously closes the door opening and places the sample can holder inside the sampler, so that it is not possible to take a sample without the door opening being closed.
    In an not illustrated embodiment of the opening, a coupling is provided between the guide and the sampling valve 5, so that the sampling valve can only be opened. The guide is in such a position that the door closes the door opening. This provides an additional degree of security for the person taking the test. Such a connection can for instance be provided with an electrical sensor in the door opening which is connected to a control device for the sampling valve and a purely mechanical connection between the control arm or the door and the sampling valve is also conceivable.
    In another non-illustrated embodiment of the invention, your rinsing water nozzles 11 are arranged at the roof so that the entire interior of the sampler can be sprayed with effluent rinsing water. Practical tests showed the best cleaning effect when two rinsing water nozzles angled in different directions are used, as the spreading angle for simple compact standard nozzles is rarely over 120 degrees.
    In the description, the test can holder is referred to as a device which receives a test can, but obviously the test can can be made in another way, for example in the form of a test tube or the like, and the designation is not limited to any particular design.
