Description

Valve for loading and unloading of containers, in the form of a bag.

Object of the invention

More specifically the invention relates to a valve specially designed for loading and unloading of bag-shaped deposits, used to transport liquids

In order to perform loading operations and  download of the contents of the deposit in the form of a bag, it has integrated the present valve in the upper part of the tank, being fully integrated into the structure of the deposit in bag form, avoiding problems related to possible breaks in the low bag valves, so the object valve of the present invention has characteristics totally novel, regarding what is understood by the state of the technique.

State of the art

They exist in the market and therefore can be considered as state of the art different types of valves, that is mechanisms used for the connection between two parts of a system, and more specifically for the transfer of products, with various types of union to each of the parts of said system and with a certain function in the execution of same, for example the threaded or welded valves that are used to section the transfer ducts, which are used to the union of pipes through quick or threaded connections.

This loading and unloading operation produces frequent breaks in the valves under the bag, having the content weight at that point.

Purpose of the invention

Provide stock-like deposits of a system of connection to the means of loading and unloading of such deposits, using the most manufacturing materials suitable according to the material used as a container.

Avoid breakage problems related to the usual valve on the bottom of the bag.

Description of the invention

In addition to the functions that are detailed more forward, the valve design has been designed to perform the loading and unloading of the products contained in the deposits in bag shape, avoiding breakage suffered by valves located under the bag, for which the present valve is made in polypropylene or other similar material compatible with the material that forms the bag-shaped tank, and is installed in the upper-central part of it.

The valve, consisting of several components, is welded to the inside wall of the tank, by a first tubular element that has a skirt that emerges from its surface lateral, its upper face being welded with the face bottom of the tank.

This type of joint, thermal welding, allows the tank-valve assembly to remain permanent solidarity with each other, ensuring the tightness of  said union.

Alternatively, it can be done in a way equivalent, the union by a tight flange system common.

To said first tubular element, in the part outside the tank, a threaded connection is attached to it washer and a counter-washer, to improve the fixing the valve to the tank, and ensure the tightness of the elbow that is installed. This washer and the anti-washer have polygonal perimeter for  facilitate tightening functions.

The last body to attach to the set is a elbow that has a threaded joint system, fixed on the counter-washer and allowing tightness of the set

Said elbow has the advantage of having a nozzle for quick connection of hoses and allow a efficiently connect to the loading and unloading system, by standard elements.

In this way the realization of the loading and unloading process of the bag-shaped deposit, through a valve that prevents breakage problems due to weight of the product contained, allows the tight connection with the loading and unloading means and its efficient connection to said media.

Other details and features will go away showing in the course of the description that to given below, in which reference is made to the drawings that to this report they are accompanied, in which by way of illustration but non-limiting a practical realization of the invention.

Description of a preferred embodiment of the invention

In one of the preferred embodiments of the invention, and as can be seen in figure 1, which accompanies here, the valve is formed by a tubular element (10) that will be permanently installed in the bag (18), as can be seen in figure 10. This union it is done by thermal welding of the upper part of the skirt (12a) that has the tubular element (10).

Alternatively, in other embodiments of the invention, the union is performed by using a system of common tight flange.

This union is tight, leaving in the inside the bag (18), a substantially cylindrical part (17) of the tubular element (10), whose lateral surface has openings (14) that allow the passage of the product contained in the bag (18). Said part (17) that is inside the bag (18), ends in a ring (15) that has protuberances (16).

Outside, there is a cylindrical part threaded (13), which allows the coupling of the other components of the set

The next component that attaches to the bag assembly (18) and tubular element (10) is a washer (19), of internal thread (23) that fits with that of the external part (13) of the tubular element (10). The washer has a diameter identical to the skirt (12) of the tubular element (10), and has outer face (20a), of a polygonal shaped protuberance (21), of circumscribed diameter smaller than that of the part in contact with the bag (18), which limits the opening (22) and allows the tightening of said washer (19) so as to ensure the tightness and the output elbow coupling (27). The washer (19) has in its inner face (20b) of some highlights (37) to ensure the tightness of the union of the washer (19) to the bag (18).

Before coupling the elbow (27), adjust a counter-washer (26), of polygonal perimeter, for correct tightening, which ensures the fixed position of the washer (19). Said counter-washer (26) shall provide optionally of longitudinal openings (24) in its body perimeter so that you can improve the characteristics of the piece.

To complete the set, there is a elbow (27), which forms an angle of 90 °, according to this embodiment preferred, although different angles could be applied according to needs

Said elbow (27) has two parts, the part which is coupled to the rest of the assembly (31), which follows the direction of the rest of the set, and the one that is intended to connect with the rest of the installation and loading and unloading means (32), which changes the set address

In the connection part (31) to the rest of the valve, there is a widened part (30), which in its inner surface is threaded (36), so that the diameters and threads fit the rest of the set and specifically with the thread (13) of the tubular element (10). From this way the elbow (27) is coupled and the assembly prepared to connect the hose that will transport the product to contain from its origin or to its end.

For this mission of connecting the hose, and do it more efficiently, you have in this embodiment preferred, of a quick take, consisting in that at the ends of the final part of the elbow (32), it has the outer surface adentellada (33) and a stop or skirt (34) that fixes the position of the hose. Thus in other embodiments one could have an elbow (27) with various forms of output connections.

Suitably described the present invention in correspondence with the attached figures, it is easy to understand that any modifications of detail deemed convenient as long as it does not alter the essence of the invention that is summarized in the following claims.
