for: "Pressure regulator for liquid lines".

- 2 - v '- Description Memory -

The present application for registration of a patent for an invention relates to a pressure self-regulator for conduction of liquids, in accordance with the detailed description which will be produced thereof, having to interpret all of its concepts in its widest sense.

In particular, it relates to an automatic constant pressure controller, applicable in localized irrigation systems based on pipes and porous membranes by ob circulating liquids, such as water with the inclusion of fertilizers.

This new pressure autoregulator, will allow in an automatic way, to maintain a constant pressure in the conduction of liquids where it will be applied, independently of the oscillations which exist before the mentioned automation. In addition, by means of this, one will get to regulate the pressure of the installation that controls the mechanism, being able to make that it varies from a few cms. c.e., up to several meters c.e., - = it does not matter the pressure existing before the mechanism, because it can always be reduced and / or maintained according to the needs of the use for which it is intended.

The self-regulating mechanism which will be interposed in the liquid conduction, in which one tries to obtain a constant pressure, consists essentially of a hollow body provided with two sockets for connections to the corresponding inlet and outlet pipes, as well as a third socket to which a weir pipe will be coupled, carrying in its interior a tilting closure piece united to a wire ^ ui flows through the weir and which is fixed by the other end to a tilting lever from which in turn hangs a container which is united by means of a pipe, with its own outlet conduction.

With this arrangement, the liquid at the beginning of the cycle, passes through the body which is fully open, and fills the entire installation which it is claimed to regulate. As the liquid continues to enter, it will begin to level up through the pipe connected to the outlet conduction until it reaches the position of the upper container.

The increase in weight that this container will experience, will actuate the lever from which it is suspended and this in turn will pull wire which will rock the closure piece located on the body which will block the liquid inlet, until reaching to completely stop the entry of it, and thus we will have obtained a situation of static equilibrium.

If at any time there is a consumption in the installation, the level of the liquid in the container will drop and consequently its weight, consequently this force disappearing, the sealing part will open again, allowing a passage of liquid greater than the consumption which is taking place, which will cause a new rise in the level of the liquid in the container, will increase its weight, which again will cause the movement of the lever and consequently, a decrease in the amount of liquid to enter oe which means that at the end of the cycles, we will arrive at a situation of equilibrium in which the weight of the container will allow to pass only and exclusively the amount of liquid which is being consumed, the mechanism being able to remain indefinitely in this situation of dynamic equilibrium, during which its operating base, is a pressure drop which automatically varies by lowering any pressure of th entered until the one we want to have, j! For the proper understanding of this object, a sheet of plans is attached to the present descriptive memory, on which a preferred embodiment is shown.

On this sheet of plans cited, a longitudinal section of the entire mechanism or installation of a pressure regulator is shown, on which the following main parts appear with references: The self-regulator has a hollow body as its central element - 1 - which provided on its anterior plane - 2 - with a sleeve - 3 - internally tapered and with an external ribbed edge - 4 - and located on the upper vertex and to which the liquid inlet pipe will be coupled - 5 -, bearing in diagonal position Ιλ ”- 4 - opposite this sleeve, another sleeve - 6 - cylindrical by its internal part, and also striated by the external one since it will correspond with the own liquid outlet in which it will be found re-strung with the corresponding pipe - 7 -. These two sleeves - 3-5 -, are located horizontal, although at a different height, incorporating the body - 1 -, a last and third vertical sleeve - 8 -, located on the upper plane and rear part, which is cylindrical internally and streaked from the outside and to which a vertical pipe - 9 - is assembled which acts as a weir and which allows both the passage of a wire or pulling - 2JD - of activity of the whole mechanism.

Inside the body - 1 - and occupying its central part in a horizontal direction, a tilting or closing piece - 11 - is pivotally mounted, which by its front part remains retained between ears - 12 -, integral with the internal frontal part of the body and secured by means of a pin shaft - 13 - which acts both as an axis of gyration. This closure part will carry an upper cuff - 14 - provided on its face with an elastic plate - 15 -, which in the closed position of the mechanism will seal the mouth - 16 - of the liquid inlet by making it hermetically this being due to its own elasticity and to the system pressure.

On the upper part of the mechanism and above the overflow pipe - 9 - is mounted a lever - 17 - by means of a rigid support - 18 - and by means of a pin - 19 - which will act as an axis gyration or tilting of this lever, which is furrowed longitudinally by a series of small holes - 20 -, One of the ends of this lever and through one of its holes, it receives a wire - 10 - emerging from the pipe even weir and which at the same time will be integral with the end of the closure piece - 11 - to which it will be fixed. At the other end of the lever, and hanging from a suitable hook - 21 - suspended from one of the holes, will be located a container - 22 - and by means of its adjustment we can establish the pressure level of the installation, the base - 5 - of this container remaining united to the same liquid outlet pipe - 7 - by means of a pipe - 23 - which will make communication between the two subject with the rise of the liquid in function of the operating pressure, until occupying the space of the cited container.

Operatively the mechanism will start when the liquid trying to spread begins to rise through the piping - 23 - so that it arrives inside the container - 22 - which being suspended in equilibrium, there will come a moment when its own weight will cause it to move downwards, - and thus the lever - 17 - by tilting, will pull wire - 1D - and this one. Ci in turn from the end of the closure piece - 11 - such that the bale that its front cuff aims to get into position facing the - mouth - 16 - liquid inlet, until the thread tension - so great that the elastic plate - 15 - hermetically adjusts the above-mentioned mouth, staying in this position, until there is no demand for liquid from the outlet pipe .

The pressure of the conductions controlled through the micanis-- · me will correspond to the height of the water that the container - 22 - will have, and which we can vary easily and simply by locating the dream. container at the required height.

No matter how high the pressure during conduction, it can always be controlled simply by varying the length of the lever arm - 17 -.

- 6 - * * - The nature of the model being sufficiently described, it is pointed out that any modification of detail that we introduce into it will remain included inside this protection - as long as it does not essentially change or modify its characteristic purpose.
