THE FITTING CAN BE SCREWED ON THE ORIFICE OF A TANK. IT CONSISTS OF TWO TRUNKS OF TUBE 2, 4 TELESCOPIC, A SPRING 16 TENDING TO SPREAD THEM, AND A VALVE 13 WHICH CLOSES THE FLOW WHEN THEY ARE DISTRIBUTED. FLOATS 17 LIMIT THE MOVEMENT OF THE VALVE 13 DOWNWARDS WHEN THE TWO TRUNKS 2, 4 ARE RETRACTED, AND MAY FURTHER APPLY THE VALVE 13 AGAINST A NEEDLE SEAT 20 TO INTERRUPT THE FLOW WHEN THE FLUID INVASES THE PART BOTTOM OF THE FITTING. USE TO PREVENT SPILLING UNTIL THE FITTING IS ENGAGED IN THE FILL HOLE OF A RECEIVING UTILITY, AND TO INTERRUPT THE SPILLING IF THE UTILITY IS FULL.

Description

The present invention relates to a valve-controlled pouring connection, and

  can preferably screw on

a reservoir.

  It is known to place such connectors on the discharge port of tanks to facilitate the spill when you have to tilt the tank to transfer its contents into another container. This operation is carried out for example when, with a liquid contained in a storage tank, the receptacle is filled with a device which employs

this liquid.

  In the case of dosing devices, the disinfecting liquid

  for example, the proportion of which must be

  other liquid, is brought directly from a storage container

  ckage to the measuring device. In this case, the disinfectant or similar liquid is usually extracted by suction.

in the storage tank.

  The present invention aims to achieve

  of pouring inrcation which makes it possible to

  see storage on a receiving container, filling

  of the latter by the storage tank being obtained automatically

  matically. According to the invention, this object is achieved by a pouring connection of the kind mentioned at the beginning of this introduction, said connection being characterized in that it comprises two tube sections that can slide one into the other by two of their parts. , a shut-off valve arranged inside these

  two parts and opening by axial pressure on the sections

  and a float needle. This arrangement allows, with a tank provided with a connection according to the invention, to reverse with the connection below without the contents of the tank escapes. If we now hold the tank in this position on a receptacle or a measuring tank, and if we slide them towards each other.

  two parts of the tubes, the shut-off valve opens and the

  float water comes into action. In this way, one avoids on the one hand an overflow of the container or the tank, and one

  can, on the other hand, remove the tank again without

pandre the content.

  According to another feature of the invention, at least one of the two sections has a shoulder with a valve seat, a compression spring resting on one side on said shoulder and on the other side on the shoulder. another section, and a shutter cooperating with the seat formed in the aforementioned section is attached to the other section. So, the

  shut-off valve may open under the action of an external force

  a lever that can be locked, or simply under the weight of the storage tank when installing it on the tank opening to be filled, the two parts of the tube pourer slide one towards

  the other. If this external force is removed, for example

  by unlocking the lever or lifting the storage tank, the shut-off valve closes automatically. For

  this, the valve seat or shutter blocking the

  through the spout can be arranged too

  well in the upstream part than in the downstream part of the fitting.

  Another feature of the invention provides that the two sections each have a shoulder with a

  valve seat, that the shutters allocated to the two

  are connected together in a valve body by means of a rod, that the compression spring is installed between

  both shoulders and apply the seats against the ob-

  when the sections are not under load

  axial, and that a stop, disposed in one of the two sections,

  the relative displacement of the valve body vis-

with respect to said section.

  In this case, the advantage is that the valve body is not integral with any one. two parts of tubes, and one

  can thus compensate for manufacturing inaccuracies

  the position of the seats in each part of the tubes or the formation of the shutters and seats, for example by a very slight obliqueness of the valve body with respect to the

axes of the tubes.

  It is furthermore provided according to the invention that the seat, the shutter and the float of the needle can be arranged in one of the two sections of tubes. On this subject, it is useful, when one needs for example a connection poureur

  very long, to be able to place the needle downstream of the

  pope stop, the free end of the pourer connection, in the-

  what is the needle set, then determining the level

  liquid in the container to be filled. Another particular

  of the invention consists in that the seat and the closure

  the needle can be arranged in one pipe section, while the float is housed in the other section

  and connected to the shutter by a rod or the like.

  A compact construction of the pourer connection thus becomes possible.

  The invention further provides that the shutter of

  water can be placed on the body of the shut-off valve. The

  Valve body can thus be manufactured in one piece.

  A further feature of the invention

  in that, in the direction of flow, the seat

  the needle is arranged in one of the sections before the shoulder

  a seat for the shut-off valve, and the float is disposed in the other section after the shoulder having the seat for the shut-off valve, in that the valve body, at its end disposed in the first aforementioned section, carries a shutter cooperating with both the seat of the needle and the seat of the stop valve disposed in this section, and in that in the other section, the stop limiting the relative displacement of the body of the valve is formed in the form of a stop disposed downstream of the float which it limits the relative displacement

  in the section, said float being able to press on the obturator

  stop valve disposed in this section. This configuration provides a very great compactness of construction of the pouring connector according to the invention, which allows to sit

  directly a storage tank on a food container

  Maintain, the filling level may arrive just below the outlet of the tank on which is mounted the pourer. Finally, it can be useful according to the invention, a seat and the associated shutter of the stop valve

  at the same time form the seat and shutter of the needle.

  Other features and advantages of the invention

  will emerge from the description which follows, of a mode of

  realization given by way of non-limiting example, in

  in the accompanying drawings, in which: FIG. 1 is a sectional view of an example of a

  embodiment of the invention with the stop valve in position

  closure; and FIG. 2 is a view of the embodiment of

  Figure 1 in the open position.

  In the example shown, the pouring connection con-

  form of the invention comprises a first tube section 2 provided with a collar 1, and can be screwed by means of a cap nut 3 on a flow connection of a reservoir,

  and a section of tube 4 that can be driven into a

  fill or the like of a container until

  said section 4 rests at the edge of the opening

wise by a stop 5.

  The first section 2 is telescopically mounted by a tube portion 6 in a tube portion 7 of the second section 4. The two sections 2 and 4 can be inserted into one another until the part 6 of the first section 2 abuts by its free end 8 against a shoulder 9 formed in the second section 4 and in which is formed a conical valve seat 10. The first section 2 is also

  provided with a shoulder 12 having a valve seat 11.

  Two shutters 14, 15 formed on a valve body 13 and cooperating with the two seats 10 and 11 block

241? - 76

  the flow through the interengaged parts 6 and 7 when they come to bear against their associated seats 10 and 11 when the sections 2 and 4 are

  away from each other (Figure 1). The distance between

  2 and 4 is due to a compression spring 16 disposed within the parts 6 and 7 which rests against the two shoulders 9 and 12 with seats 10 and 11. When the sections 2 and 4 are not subject at axial load, the compression spring pushes them back until the valve body 13 blocks the flow and thus prevents a more

wide spacing of the sections.

  The assembly constituted by the valve body 13 and the seats 10 and 11 forms a spring-loaded shut-off valve,

  placed within Parts 6 and 7, which blocks the

  flow through the connector until the parts 6 and 7 begin to slide into one another, thereby detaching

  the valve body of the seats 10 and 11 and thus releasing the

flow (Figure 2).

  Since the shut-off valve does not release the

  in the shoulder 12 of the first section 2 that

  cordance with the relative displacement of the valve body 13

  compared to the first section 2 in the opposite direction to the

  flow, there is provided in the second section 4 a stop for the relative displacement of the body 13 vis-à-vis the second

  section. This stop limits the opening stroke of the ob-

  14 of the seat 10 in the shoulder 9 of the second section, so that the relative displacement of the seats 10 and it towards each other is greater than this race. We

  ensures that the shut-off valve for the contents is

  lant of a tank through the spout can close.

  In the embodiment shown, this stop for the valve body is formed by an abutment preventing out of the spout a float 17 disposed in the second section. This stop may consist of a bar 18 inserted radially in the second section, several floats 17 being able to be arranged between the bar 18 and the body of

  valve 13, provided only that the latitude of movement

  body 13 is less than the sliding path-

parts of tubes 6 and 7.

  The float 17 disposed in the second section 4 and adjoining the valve body 13 cooperates with a shutter 19, disposed at the other end of the valve body 13, and

  associated with a seat 20 disposed in the first section.

  In this way, the entire valve body 13

  with the seat 20 and the float (s) form a

  float water which only comes into play in the case of

  shut-off valve, which is controlled by the

  filling level of the container to be fed.

  Alternatively, the valve body 13 and the relative position of the seats 10, 11 and 20 may be arranged such that when the float needle is closed,

  With the shut-off valve open, the valve body

  as well on the seat 20 as on the seat 10 also

  LEMENT. The pouring connection according to the invention is used as follows in the case of filling a small container, for example a dosing pump, with a reservoir such as a supply can: the pouring connection is screwed onto the outlet of the can, the latter being in fact closed so that no leakage can take place at the head of the can, but can be emptied at any time by

  pressing on the fitting to retract the latter on itself

  even. To retract the connection, and cause the opening of the stop valve, is pressed through its pouring connector, the spilled can into the inlet port of the container to be filled until the collar 5 abuts against the edge of the said

  orifice, the weight of the can then retracting the

  Agreement. The content of the can then flows until the

  Float needle locks the flow through the fitting.

  If the container empties, the needle opens and the contents of the can empty until the needle closes or

  that the can is previously completely emptied. The can

  even if it is already empty or full, can be removed at any time from the container to be filled because, when the pourer is removed from the filling port, the stop valve closes and prohibits any flow of the can content. In the context of the invention, the stop valve of the pouring connection can naturally be also actuated by a lever that can be locked or the pourer connection can be arranged obliquely with respect to the vertical. Similarly, the filling level of the container to be fed can be modified by the length of the tube sections, or by

  the size or number of floats.

  In addition, the connection can be given a

  total distance as it can bridge the distance difference, depending on each particular case, which separates a container

  fill in a favorable position to place the

see storage.
