Description

Heated water supply installation, especially for

  The invention relates to a warm water supply installation, in particular for free and open stabling stalls, comprising at least one water-carrying device connected to a pipe.

  water inlet, possibly equipped with a non-return valve, in particular

  attaching an automatic watering trough with a livestock-actuated water outlet valve, which is bypassed to the inlet line, the water being reheatable by means of an external resistance heating element in at least one segment of the supply line, which eventually follows the check valve, upstream

  the first water-carrying device.

  In an installation of this kind which is already known from

  DE-A-35 45 815, the inlet water pipe is extended downstream of the.

  last water-carrying device (drinking trough), through a return line

  water that opens into the inlet pipe downstream of a check valve.

  back, to form a looped pipe in which circulates water which is heated in a segment of the inlet pipe which is provided with heating, this water being connected to each debiting device (waterer) by a conductive connection of heat, in order to heat the debiting devices. Here, the outlet valves of the debiting devices (waterers) are mounted directly on the inlet pipe,

  which can also be formed by parts of the devices de-

  debtors. This known installation has a relatively high installation and operating cost for the circulation and heating of the water, which must generally be circulated by a pump. The invention therefore aims to create a water supply system with heating that avoids this disadvantage, especially for stabling free and open housing, which is a relatively simple construction and whose current consumption is

  reduced to equal heating power.

  According to the invention, this problem is solved in a

  of the kind mentioned at the beginning, in that the water supply line terminates at the level of a last water

  in front of each upstream water-inflating device without being sensi-

  in a heat conducting connection with it, an outlet valve of the device being connected to the inlet pipe, possibly by means of a stitching; and in that the segment of the inlet pipe that can be heated. is formed, upstream of the first debiting device, in the form of a water reservoir which encloses the heating element. This installation according to the invention must be conducted in such a way that the last water-carrying device discharges water.

  with sufficient frequency and / or flow, depending on the temperature

  of the water contained in the tank, which can be adjusted

  room temperature so that the temperature of the water remains

  always above the freezing point of the water passing through the

  even when arriving at the last water-carrying device. For example, in a barn installation, this can be achieved by providing, as the last water-carrying device, an automatic watering trough placed in a stall or box which is constantly occupied by a sufficient number

of animals.

  The fact that the water supply pipe ends at the right

  of a last water-carrying device makes it possible to dispense with the

  return of the looped pipe and a possibly planned circulation pump that consumes electricity. The fact that the water inlet pipe passes in front of each of the water-carrying devices mounted upstream of the last water-carrying device without being

  substantially in a conductive heat connection with it does not.

  that avoiding a constant heat transfer of the heated water contained in this pipe to the parts of the installation and the surrounding air but also allows to remove the various through pipes automatic waterers of the known installation. Compared to

  this construction, a traditional stitching leading from the management of

  The exit valve is a relatively small expense.

  Finally, thanks to the heated water tank, a quantity can be

  relatively large temperate water, which is sufficient to cover the water needs through the reserve when the water is discharged by at least one

debtor device.

  The invention thus makes it possible to advantageously achieve the aim of reducing the cost of installation and operation.

  without being penalized by a new disadvantage.

  In a preferred embodiment of the installation according to the invention, the water tank is constituted by a raised tank without pressure, in which a segment of the inlet pipe, which is connected to the water distribution network. , leads through

  an outlet valve controlled by the water level, for example, com-

  sent by a float. This installation configuration avoids the need for

  of excessively high water pressure in the distribution system and the need to install a non-return

the arrival pipe.

  The preferred embodiment, which is designed for free-standing barns which include automatic waterers as water-carrying devices and which is particularly well suited for such installations, is characterized by at least one electromagnetic output valve (a solenoid valve) controlled by the temperature of the water present at the valve, which is the last water-carrying device and / or a water-discharging device arranged on the inlet pipe between two automatic waterers. This solenoid valve, which is electrically connected to a temperature sensor which can be provided, for example, at the end of the inlet pipe, ensures that there always occurs a discharge of water when the temperature of

  the water falls below the set safety threshold, and the measuring point

  sure of the temperature is always fed with temperate water. The discharge

  water on the floor of the barn is not a disadvantage because this

  usually consists of a slatted floor,

  to the slits from which water can flow into a manure tank

  placed under the floor of the barn. -

  In the preferred embodiment of the invention, which

  as in the known art, at least one vertical segment

  of the inlet pipe, the upper end of which connects to an inlet pipe segment which is preferably horizontal,

  at this connection, an electric resistance heating element is provided.

  connected from the top, which plunges into the vertical segment of the con-

  end of the segment, through the upper end of this segment, to

  that the water contained in this segment of the pipe can be heated in the case where the heating power of the heating element contained in the water tank is insufficient, for example, in the case of a particularly strong jelly .

  In the preferred embodiment, each watering trough automatically

  that is provided, at its lowest point, with a hole in the wall that may

  possibly be closed when the outlet flap corresponds to

  green and which, otherwise, is closed for the most part by means of a stopper provided with a calibrated bore. As a result, the water contained in the trough can flow gradually through the hole in the front wall of the trough.

  risk freezing. One of these two variants can be chosen, in parti-

  in the case where, except in the preferred embodiment, an electromagnetic output valve controlled by the temperature in point

  of the supply line or in the case of water troughs

  in this location remain unused for specific reasons.

  In the preferred embodiment, the water inlet pipe is provided with a nozzle placed in particular upstream of a solenoid valve and terminating in a manually-controlled water-feeding device, for example, at a tap which is connected by a hose to a spray lance

  manual used for cleaning. In this way, this device debits

  water is also constantly supplied with water at a temperature above the freezing point if the frequency of the discharge of water

  is not too small in the case of a long-term derivative

LATIONS.

  In another embodiment, the water reservoir has a

  elongated form and extends horizontally, its lower third contains

  the heating element while, its upper third, contains a deflector assembly returning down the hot water that rises. This

  ensures the water even when it passes through the tank, a time of

  enough time to warm up enough.

  In this construction, it is preferably provided that the reservoir

  see water is divided into two parts, roughly in the middle and that, at least in the case where the water inlet of the tank is vertical, a baffle is mounted fixed to reduce the flow of water to the water. 'horizontal, in order to facilitate the assembly of the tank or to lengthen even more

the aforementioned residence time.

  In an installation where the heating element is equipped with a

  a heater current connected to a temperature sensor and having an element for setting the set temperature of the water tank, as is already the case for the known installation, this other embodiment is d a configuration in which the heating element comprises two elongated U-shaped loops, the planes forming a right angle between them; and o the heating current regulator is mounted externally on the water tank, the temperature sensor, as well as the heating element, penetrating the interior of the tank through the wall of the tank. In this way, the heating and regulating device of the water tank can be

  mounted on this tank, and replaced if necessary, in a simple way.

  Two embodiments of the heating plant

  water supply for a free stall barn according to the invention will be

  described hereinafter by way of example with reference to the accompanying drawings.

  Figures 1 and 2 of the drawing respectively show first and second embodiments, each shown as follows

a simplified side view.

  According to FIG. 1, the first embodiment is essential-

  consists of a water inlet pipe 10 bent at a right angle,

  a non-return valve 12, a water tank 14 equipped with a device

  tif of heating and regulation 16, a first automatic watering trough 18 constituting one of the water-carrying devices and a second

  automatic waterer 20 which is the other device water debtor.

  The inlet pipe 10 is constituted in turn by a first vertical segment 10.1 which comprises the non-return valve 12 and which is

  equipped with an insulation 22 terminating at the level of this valve, and which

  from the floor or floor of the barn to the tank 14, by a second vertical segment 10.2 which rises from the tank 14 to the level of the

  upper edge of a stall wall not shown; and two segments

  horizontal 10.3 and 10.4, which are connected, one to segment 10.2 and the other to segment 10.3 of the incoming pipe,

  by means of an elbow 24 and a T 26. The connection of the vertical segments

  10.1 and 10.2 of the supply line to the reservoir 14 is achieved by means of two screwed connections. It would be advantageous to also insulate the segments 10.2, 10.3, 10.4 of the inlet pipe, as well as two vertical taps 28 and 30, as well as the segment 10.1.

  of the arrival pipe if heavy frost is to be expected.

  The reservoir 14 is composed of two symmetrical halves with

  port at a point, in the drawing plane in configuration and in

  14.1 of the inlet pipe and has, above the connection point, a horizontal baffle 32 which deviates to the right in the drawing and to the horizontal, the water that comes from below and stumbles on this baffle; on its side, the 14.2 half of the reservoir

  on the right side of the drawing is connected to segment 10.2 of the

  riveted and has, below the connection point, a horizontal bend

  corresponding zontal 34 which prevents water from flowing up and down along the edge of the tank below the water intake. The reservoir 14 is of elongate shape and disposed lying or horizontally. In its lower third, it contains an electric resistance heating element 36 belonging to the device 16, which is at the height of the baffle

  lower 32, while in its upper third it encloses a

  the deflector 38 is located above the level of the upper baffle 34, to serve as a water baffle, and which extends into the space between the two baffles 32 and 34 and makes the hot water which rises above the heating element 36 is returned down in all areas of the deflector assembly 38, so that the water

  already warmed up is still heating up and reaches the temperature of

  This tank is divided into two parts in the middle and its two halves can be assembled to one another by means of flanges 14.3 and fixed to a stall wall or

stable with legs 14.4.

  Below the upper baffle 34 is provided a heating current regulator mounted externally against the tank 14, and

  which is part of the heating and regulating device 16, which regulates

  which is connected, on the one hand to the electricity network, via

  of an electric cable 42 and a FI circuit breaker not shown,

  and, on the other hand, both to the heating element 36 and to a sensor of.

  temperature, not shown, the device 16, the latter further comprising an element 44 associated with the regulator and which sets the target temperature of the tank. The heating element 36 comprises two elongated U-shaped loops 36.1 and 36.2, one in a vertical plane and the other in a horizontal plane, that is to say which form a right angle between them, and likewise the temperature sensor,

  it has passed through an opening in the tank wall,

  right o the heating current regulator 40 is mounted, so that the heating and regulating device 16 can be removed from the

tank 14 as a single block.

  The first drinking trough 18, connected to the T 26 of the inlet pipe via the first sewing 28, is in a stall

  free circulation occupied by several animals. At the lower end

  taper 28, the first drinking trough 18 is provided with a check valve

  incorporated water outlet, not shown, which opens under the action of a.

  pallet 46 for controlling the flap, of the oscillating type, when the animal

  lowers it against the force of a spring and closes when

  that the pallet is released. In this construction, the bottom of the

  the drinker is pierced with a drip hole through which less water flows than it does when the valve is half open, this hole being closed by means of a sealing washer 50 fixed on the underside of the pallet 46 and which rests on the edge of the hole, for

  avoid unnecessary water loss during the arrival of water into the water

  see. On the contrary, during the stops of arrival, the water contained in

  the unheated drinking trough can flow gradually and, more

  quickly enough so that the water still contained in the trough

  does not freeze under normal ambient temperature conditions.

  The second waterer 20 connected by the second tap 30 to the end of the inlet pipe segment 10.4 which is the furthest away from the T 26, by means of a second bend 52, is in a

  individual stall which is occupied by only one animal. At the ex-

  lower end of the stitching 30, is screwed an outlet valve 54 which is suspended in the down position a tube 56 for actuating the

  flapper that the animal can deviate laterally. This tube is placed

  above the lowest point of the drinking trough, where there is provided a wall hole 58 corresponding to the drainage hole 48, of relatively large diameter and which is closed for the most part by means of a plug 60 pierced with a narrow calibrated bore 62 so that, here too, the water flows at a flow rate so small that the trough is gradually emptied

  but it fills when the valve 54 is half open.

  When the valve of the drinking trough 18 or 20 opens, and depending on the duration of the opening stop, firstly flowing hot water more or less cooled, from the corresponding quill 28 or 30

  and the adjacent segment of the finish line 10, until

  subsequently, a still sufficient quantity of hot water arrives from the tank 14 in the trough if the outlet valve of this trough has not already been closed beforehand, and, as a result of this flow, there is in all case of hot water presenting the set temperature in

  the inlet and in the tapping, between the tank and the water

  see, so that these pipes are not likely to freeze.

  elements of the two mutually corresponding forms of

  Different references are used, plus 100.

  As in FIG. 1, the second embodiment consists essentially of a water inlet pipe 110, here also bent at right angles, of a water tank 114 with its heating and regulating device. , the first automatic drinker 18 which

  is one of the water debtor devices, and the second water

  On its side, the arrival line is composed of a first horizontal segment 110.1 coming from a water distribution network

  not shown and leads to the tank 114; of a first vertical segment

  110.2, which descends from the tank 114 to the level of the upper edge

  a stall wall, not shown; a second segment '

  10.3 which is connected to line 110.2 of the control line

  riveted by means of a first elbow 124; a second and a third vertical segment, 128 and 168 respectively, arranged next to one another and which, at the bottom, are connected to one another by means of a shaped segment U at the top, they are connected by means of two elbows 172 and 174, one to the segment 10.3 of the inlet pipe and the other to a third horizontal segment 10.4; a fourth horizontal segment 176 which is connected to the segment 10.4 of the inlet pipe by means of a T 152; and a fifth short horizontal segment 178 which is connected to the incoming line segment 176 by means of a second T 180 and is provided with an electromagnetic output valve 182 constituting the last water-carrying device, however that, to cause the solenoid valve to be controlled by the temperature of the water present, there is provided an intercalated temperature sensor 184. The connection of the segments 110.1 and 110.2 of the inlet pipe to the tank 114

  is here also achieved by two screwed joints. It would be here also

  to insulate all segments of the inlet pipe for

  As the penultimate device for water delivery, there is provided a tap 186 connected to T 180 by means of a vertical branch pipe 188 and, in the embodiment, a hand-held spray nozzle 190

  is connected to this valve by a pipe 192.

  The tank 114, with its heating and regulating device,

  116, may be of a configuration that corresponds to the tank 14 provided with its heating and regulation device 16t but instead of the connection of the segment 10.1 of the inlet pipe, we find here

  the connection of the 110.2 segment of the supply line, and the connection

  Segment 110.1 of the incoming line is intended to replace
