Definitions
- the present invention relates to a valve and a device for valve, more particularly a valve intended to be suitable for containers containing a product to be ejected under the pressure of an internal gas, with or without foaming. It can in particular be a polyurethane bottle with a component.
- the present invention provides a valve design simple which allows the use of the cylinder in position straight or flipped.
- a valve system is in fact provided consisting of a classic valve ("tilting valve") which is coupled to its lower part, inside of the container, a device comprising a chamber connection on the one hand with the valve and, on the other hand, with the interior of the container via two routes.
- tilt valve classic valve
- One of the tracks includes a ball, of diameter making it captive, acting by gravity to block the passage into upright position preventing product introduction in the chamber, and therefore towards the valve itself.
- This channel connects the chamber to the contents of the cylinder upper level of it.
- the other way connects the room to the contents of the cylinder at the lower level of it, through a internal tube dipping towards the bottom of the container.
- the product to be ejected is found in the bottom of the cylinder, goes through the tube dipping, being compressed down by the phase upper, preferably a gas, to go up towards the bedroom.
- the phase upper preferably a gas
- the upper access route to the chamber includes an open longitudinal duct laterally towards the inside of the container and open to bottom towards the interior of the room.
- a moving ball between an open position (towards the head) and a position closed (towards the bottom) can move by gravity position to the other, corresponding respectively to a returned layout and a straight layout of the carboy.
- the ball rests by gravity on a seat provided for this purpose and is held there by the pressurized gas phase in the part superior of the cylinder.
- the device can be connected to the valve by a piece adaptation, preferably metallic, of the valve to container.
- This piece includes at its base a short cylindrical extension comprising an annular groove in which the upper edge of the cylindrical device according to the invention can be adapted by clipping.
- the chamber and the channels can be in the form of a single element, possibly molded in one piece, approximately cylindrical.
- the device can consist of two parts cylindrical overlapping the lower part can be adapted and secured to the base of the upper part, and comprising the openings as well as the captive ball.
- the lower cylindrical part can be presented under the form of two open longitudinal ducts, the end upper part of the duct, duct comprising the openings, being closed by a closing element, for example under the shape of a plug or lid, to form the wall upper of the ball housing.
- This arrangement can facilitate mass production.
- valve device is completed by another device provided at the end of the tube plunging.
- a device additional is advantageously adapted to the end bottom of the dip tube. It is a room also containing a ball capable of adopting two positions different under the effect of gravity. The ball adopts a locking position of the tube access in position returned.
- the chamber therefore includes an access path to the tube and openings, preferably lateral, towards the interior of the container.
- the size of the ball is as it is kept inside the room. In the upright position, the ball rests on the bottom of the chamber and the contents of phase B can enter the room and go up in the tube towards the valve when the latter is actuated.
- the bottom of the chamber can be a cover closing of a metallic or molded cylindrical piece.
- the device and its components can be made of different materials, including metal.
- the marble is preferably metallic but the walls (20,20 ') preferably be made of plastic, for example polypropylene.
- Figure 1 is a section showing the device to valve 2.
- Container 1 in the upright position contains two compounds under pressure, creating two phases A and B respectively upper and lower, depending on their density.
- a valve 2 of conventional type eg "tilting valve”
- a valve 2 of conventional type is fixed to the container using an adapter 5 in the form cup with hole in the center, at the base of which has the device according to the invention has been joined together.
- the device 20, 20 ' is inside the container and contains interior access to valve 2.
- the device 20, 20 ' is intended to allow access to said valve, and therefore the ejection, to only one of the two phases A and B.
- the device comprises a chamber 3, 3 ' connected to valve 2 and connected by two channels 10, 11 to the interior of the container 1, one of the channels (11) being connection with the upper part of the container and the other channel (10) being in connection with the part bottom of the container.
- Channel 10 opens towards a tube 4 dipping into the bottom of container 1.
- the way 11 has two openings 12, 13 respectively towards the chamber 3 and towards the upper (head) part of inside the container.
- ball 14 for example metallic, movable in the duct 11 under the effect of gravity.
- the opening 12 for communication towards said chamber will be blocked by ball 14, for example metallic, movable in the duct 11 under the effect of gravity.
- the opening 12 for communication towards said chamber will be blocked by ball 14, for example metallic, movable in the duct 11 under the effect of gravity.
- the opening 12 for communication towards said chamber will be blocked by ball 14, for example metallic, mov
- Phase B can for example indeed be a prepolymer of one component polyurethane and phase A will be a gas.
- the device is connected to the valve by the part adapter 5 from valve 2 to container 1.
- Part 5 in cup shape has a cylindrical extension at its base having an annular groove 7 in which the rim upper 8 of the cylindrical device (20 ') according to the invention can be adapted by clipping.
- Fig. 2 illustrates in section an advantageous variant of the invention, in which the device 20, 20 'is completed by a second device 21 provided at the end of the tube dipping 4.
- a chamber 22 with an opening 23 towards this tube 4 having a perimeter 23 'forming a seat for a ball 25, and side openings 24 towards the inside of the container.
- Ball 25 can take two positions P (free passage) and P '(blocked passage), under the effect of the gravity, depending on whether the cylinder is in the straight position or returned.
- the ball can be held in position blockage by pressure of the lightest phase, by example a compressed gas.
- the device is advantageously cylindrical and may include a fixed bottom cover 26 in known manner to a room a molded cylindrical.
- the ball can be replaced by any moving element likely to obstruct the passage under the effect of gravity. It can also be a hollow cylinder with a sliding side opening in a section tubular, said opening being able to coincide, in position returned from the container for device 20 and right for the device 21, with an opening provided in said tubular section and communicating with the interior of the container.
