Abstract

Straight anti-return link for fluid conduits, which being intended to be connected at its ends with other sections of a fluid conduit, is characterized in that it comprises a narrowed tubular narrowing (1) limited between two lateral extensions (2) and (3), in one of which (2) is inserted a perforated front disc (4) delimiting a chamber (5) disposed between said perforated disc (4) and a corresponding circumferential seat (7) with one of the ends of the narrowing centered ( 1), chamber (5) where a spherical body (6) is loosely located which is capable of closing that centered tubular narrowing (1) when that spherical body (6) frontally rests on that circumferential seat (7) as a consequence of the sense of circulation of the fluid from the chamber (5) to the centered tubular narrowing (1).

Description

Straight non-return link for pipes fluids

Object of the invention

The present invention, as expressed in the set forth in this specification, refers to a straight link non-return for fluid conduits presented by the particularity of incorporating a device inside non-return valve that as its name indicates lets pass fluid in one direction of circulation and not in another, so that thanks to the incorporation of the valve in the straight link itself it is not necessary to insert a non-return valve properly said in the conduction of fluid.

Background of the invention

At present the valves are known non-return which generally comprise a tubular structure and the which have the mission of letting fluid flow through them in one direction while in the opposite direction of circulation of that fluid obstructs its passage.

Description of the invention

The straight anti-return link for pipes of fluids constituting the object of the invention comprises a tubular structure that has elements at its ends conventional to be able to connect to adjacent ends of others tubular sections of fluid conduction.

It is characterized because the straight link non-return incorporates a valve device inside integrated backflow within the straight link, device that determined from a spherical body comfortably housed in a chamber limited between an anterior perforated cap that leaves pass the fluid both ways and a rear seat circumferential of smaller diameter than the spherical body, so that said circumferential seat constitutes an end of a tubular narrowing, so that when the fluid circulates inside the straight link from the tubular narrowing towards the chamber where the spherical body is located, the current of fluid displaces it against the perforated lid, advancing in this situation freely fluid flow.

Instead, when the direction of the current is in the other direction, said current displaces the spherical body against the circumferential seat that limits one end of tubular narrowing, thus producing a seal airtight and therefore blocking the fluid flow in that direction, so that the pressure of the fluid inside the chamber will push the spherical body against the circumferential seat ensuring a tight seal.

It is therefore a non-return system integrated inside the straight link, providing a utility larger than the piece, since it will avoid the need for valves conventional additional non-return.

Next to facilitate a better understanding of this descriptive report and being an integral part of the same, a single figure is accompanied in which with character illustrative and not limiting the object of the invention.

Brief description of the drawings

Figure 1.- Shows a perspective view of the non-return straight link for fluid lines, subject to the invention.

Description of the preferred embodiment

Considering the numbering adopted in the Figure, the straight non-return link for fluid lines it comprises a tubular structure, at whose ends there are some conventional elements to connect with other sections tubular of the respective conduction of a fluid.

The internal link space comprises a cylindrical configuration that includes a centered narrowing 1 and lateral widening 2 and 3, in one of which 2 is embed a perforated front disk 4 that delimits a camera 5 where a spherical body 6 is loosely located, so that when the fluid circulates in the direction from that chamber 5 towards the centered narrowing 1, said spherical body 6 is placed dragged by the current against a seat circumferential 7 that delimits one of the ends of the centered narrowing 1, interrupting in this case the fluid circulation thanks to the sealing provided by the spherical body 6 that seals the central narrowing 1 when supporting against the cited circumferential seat 7.

Instead, when the fluid circulates in the direction opposite from centered narrowing 1 to chamber 5 where the spherical body 6 is located, then the current drag it to place it against the perforated disc 4, to through which the fluid will circulate too.

The chamber could also be placed in correspondence with the other even lateral widening arranged at the opposite end of the narrowing
centered.

Claims (1)

1. Straight non-return link for fluid conduits, which being intended to connect at its ends with other sections of a fluid conduit, is characterized in that it comprises a centered tubular narrowing (1) limited between two lateral widenings (2) and (3) , in one of which (2) a perforated front disk (4) that delimits a chamber (5) disposed between said perforated disk (4) and a corresponding circumferential seat (7) with one of the ends of the centered narrowing ( 1), chamber (5) where a spherical body (6) is loosely located that is capable of sealing that centered tubular narrowing (1) when that spherical body (6) rests frontally on that circumferential seat (7) as a consequence of the sense of fluid circulation from the chamber (5) to the centered tubular narrowing (1).
