Description

Quick connect device for pipes Hydrosanitary and heating perfected.

Object of the invention

The quick connect device for pipes improved hydrosanitary and heating supplies means that increase the tightness of the set, for what it incorporates in addition to the typical o-rings on these items placed in the central body of the accessory, a retaining ring and a elastic seal located in the bushing, all of which decreases in greatly the passage of fluid through the connection.

This invention has application in the industry of the plumbing.

Background of the invention

Currently for the connection of conduits flexible with different accessories such as joints, elbows, tees, etc. and own parts in plumbing installations, are used push and dock type connectors, so that insert the end of the pipe through the bushing and it will attaches to the body of the accessory, creating an easy connection and certain security as far as tightness is concerned.

While it is true that these links are comfortable to work for professionals, and thanks to one or two O-rings placed on the central body of the accessory, they manage to limit leaks in the installation through these points. Experience says that it is not unusual for these to occur water leaks from the installation through these connectors

In many cases the cause of the leaks is that these o-rings have fallen when the pipe or even before. What causes the water to flows under pressure, run through the insterstices formed between accessory, pipe and bushing. Another cause of leakage is the pinching or twisting of the joints, with the same result than indicated above.

Description of the invention

With the quick connect device for perfected hydrosanitary and heating pipes, object of the present invention prevents extraction on the one hand voluntary or involuntary pipeline and increases greatly measure the tightness of the assembly, since it is coupled by the face internal of the bushing an elastic retaining ring opened by its ends that once placed prevents the extraction of the pipe and on the other presses this pipe against the fitting and the O-rings

The outer face of the retaining ring is smooth and conical, so that it fits perfectly to the inner face of the cap and its extraction is impossible. The internal part of ring is formed by a series of inclined teeth designed For maximum grip on the tube. Through this piece the tube cannot be removed once inserted into the set.

In addition, an elastic joint is placed on the face internal of the bushing, specifically where the pipe and the central body, made in EPDM and presents two regruesamientos in The inner face One of them is in contact with the body central and the other with the pipe.

Under the incorporation of this meeting elastic, the tightness of the set increases considerably with respect to the other existing systems in the market, given that although all the systems of union present inside rubber o-rings to prevent the passage of water, as well as the present set is incorporated, the reality is that still the water can happen, there are cases of water leaks between the end of the tube and the central body.

By incorporating this elastic joint the passage of water is prevented both towards the tip of the bushing and towards the union between the bushing and the central body, in cases where the water can pass the two rubber gaskets of the inside.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, is accompanied herein descriptive, as an integral part of it, a series of figures in which with an illustrative and non-limiting nature, has represented the following:

Figure 1.- Represents a sectional view of a assembly of a bushing object of the present invention mounted on a plumbing fixture.

Figure 2.- Represents a sectional view of the previous assembly without joints, rings or pipe.

Figure 3.- Sectional elevation view and plan of the retaining ring.

Preferred Embodiment of the Invention

As can be seen in the attached figures a bushing (1) is distinguished first for quick connection with the pipe fitting (2) (3). The accessory itself has of one or two o-rings (4) that close the interstices between the pipe (3) and this accessory body (2).

This device features a tip of the accessory (2) with variations from what is known in the market and has been developed to offer maximum adjustment with the tube (3) and a quick and secure connection to the bushing (1).

Another component of this set is the bushing (1), preferably made of polysulfone (PPSU) and it attaches to the body of the accessory (2) by means of the aforementioned system Quick connect push-fit.

The bushing (1) has a cylindrical shape and with tapered tip on both the outside (6) and the inside (5), which facilitates the insertion of the pipe (3).

On the inside of the cap is where they have incorporated the main novelties with respect to the rest of market pieces. First of all an accommodation of conical shape (17) where the retaining ring (7) is placed.

This PPSU ring (7) has an opening (8) that allows the movement of the piece in its housing (17) of the bushing (1). Thanks to the flexibility of the material, This is compressed by closing the opening and then retrieves its form inside the cap.

The outer face of the retaining ring (9) is smooth and conical, so that it fits perfectly into the cavity (16) bush (1) and its removal is impossible. The part Internal (10) of the ring is formed by a series of teeth inclined designed for maximum grip on the pipe (3). Through this piece the tube cannot be removed once it is Insert in the set.

On the other hand, the elastic seal (11) that placed on the inner side of the bushing (1) in its housing (12) intended for this purpose, specifically where the pipe (3) and the body of the accessory (2).

This elastic seal (11) is made in Ethylene-Propylene-Diene-Monomer  (EPDM) and presents two regruesamientos (13) in the internal face, in such that one of them is in contact with the body of the accessory (2) and the other with the pipe (3).

By incorporating this device, the tightness of the assembly increases considerably with respect to to the other existing systems in the market, since in addition to carry inside o-rings (4) of rubber to prevent the passage of water, this elastic seal (11) prevents the passage of water both towards the tip of the bushing (1) and towards the junction between socket and accessory (2).

Its application and operation is simple, for this, once the accessory (2) is mounted, the end of the pipe (3) and is passed through the bushing (1) until it is look through the viewfinder (14), then the tip of the accessory (2) through the mouth of the pipe, fixing its position when the boss (15) of the bushing fit with their respective housing (16) of the accessory.

In this position the retaining ring (7) is coupled to the cavity (17) inside the bushing (1), in mode such that it presses externally on the pipe (3), which causes on the one hand that fits more strongly against the tip of the accessory (2) toothed and against o-rings (4), decreasing hollows and interstices where water could flow.

Likewise, the teeth (10) of the surface internal of the retaining ring (7) is arranged so that facilitate the penetration of the pipe but "nail" on its surface in case of extraction, favoring both fixing the pipe as it hinders any type of leakage to through this point.

Once nature is sufficiently described of the present invention, as well as a practical application of the same, we only have to add that both its form and materials and execution thereof, are susceptible to modifications, as long as they do not substantially affect the characteristics claimed below.
