Definitions
- the present invention is related to a connection system, which involves low manufacturing and installation costs, for connecting a PEX pipe, or the like, with a fitting for PEX pipe, or the like.
- Cross-linked polyethylene (PEX) pipes offer a number of advantages, such as good mechanical strength, good temperature resistance, as well as good elastic memory, among others.
- PEX pipe is semi-rigid in nature, due to which the connection systems used to connect them with fittings require clamps capable of exerting a force considerably higher than that used for the connection of flexible hoses or other types of flexible conduits. .
- the clamps used in a PEX connection must be capable of exerting an amount of force in a very narrow range.
- connection elements PEX pipe and fitting of polymeric material
- US 3,605,200 discloses a connection system that involves tubular elements and discloses a clamp defined by an arched wall at the ends of which hook elements defined by multiple hooks are arranged, which can define multiple tightening levels.
- this document discloses a triple ring flange on its inner surface that is nailed against the hose in a connected position.
- this document does not disclose the possibility of disconnecting the clamp.
- the multiple hooks define multiple hook positions which makes it difficult for this system to connection can consistently achieve optimum tightening (in a limited range).
- US 3,925,851 discloses a connection system that involves plastic hoses and a clamp defined by an arched wall at the ends of which hook elements defined by multiple hooks are arranged, which can define multiple tightening levels.
- this document discloses an annular flange, with a "V" section, on its inner surface that is nailed against the hose in a connected position.
- this document does not disclose the possibility of disconnecting the clamp.
- the multiple hooks define multiple hook positions which makes it difficult for this connection system to consistently achieve optimum tightening (in a limited range).
- US 4,291,855 discloses a pipe support system that discloses a supporting element defined by an arched wall at the ends of which hook elements defined by a single hook are arranged.
- this supporting element can be disconnected thanks to the fact that, on the one hand, the tightening it exerts is very low (so separating the hooks is not difficult) and, on the other hand, there is a significant separation between an upper hook ( 81) and an element that limits its movement (12) which allows a screwdriver (or the like) to be introduced (in said separation) to make a disconnect lever.
- the present invention is related to a connection system, which involves low manufacturing and installation costs, for connecting a PEX pipe, or the like, with a fitting for PEX pipe, or the like.
- the invention uses a clamp with engagement means that define a single engagement position which allows defining a single level of tightening very reliably.
- the present invention incorporates an annular flange disposed in an internal region of the clamp and which is intended to drive into the pipe to which the clamp is fixed, all of which allow a very reliable connection and with a minimum level of deformation of the pipe (which in turn allows the reuse of the pipe in case you want to correct the installation).
- the present invention discloses means of disengagement that allow easy disengagement of the aforementioned means of engagement (although the means of engagement involve very high tightening), all of which is very convenient when it is desired to correct a Hydraulic installation.
- the invention further discloses stop means which are arranged so as to limit the displacement of the hook means very efficiently in order to avoid, in a very reliable manner, that the clamp can exert excessive tightening while it is being installed.
- Figures 1a and 1b show a first preferred embodiment of the clamp of the invention in the open and closed conditions.
- Figures 2a and 2b schematically show the force that must be exerted to close the clamp of the first preferred embodiment of the invention.
- Figures 3a and 3b show a second preferred embodiment of the clamp of the invention in the open and closed conditions, where means for easily opening the clamp are incorporated.
- Figures 4a and 4b show a third preferred embodiment of the clamp of the invention in the open and closed conditions, where means for easily opening the clamp are incorporated.
- Figures 5a and 5b show a sectional view of the first preferred embodiment of the clamp of the invention, where the cross section thereof is more clearly seen.
- Figure 6 shows a sectional view of the first preferred embodiment of the clamp of the invention where the pipe and the fitting mouth involved in the connection are also shown.
- Figure 7 shows a perspective view of a fourth preferred embodiment of the invention which corresponds to a modification of the first mode in which structural reinforcement elements have been incorporated (which significantly improve the performance of the invention).
- the present invention is related to a connection system, which involves low manufacturing and installation costs, for connecting a PEX pipe, or the like, with a fitting for PEX pipe, or the like.
- said system includes a clamp (3) comprising two curved walls (4), a flexible joint (5) connecting a respective first end of said curved walls (4), coupling means (6) connecting a respective second end of said curved walls (4) and defining a single engagement position and consequently a single intensity in the clamping force.
- the invention further includes an annular flange (7) disposed in an internal region of said curved walls (4) that is stuck in the pipe (1) for the purpose of concentrating and increasing the effectiveness of the clamping force.
- the system may also include release means (8), which allow to disconnect said coupling means (6), which is particularly useful when modifications and / or corrections of a hydraulic line that are being manufactured (or that have been made) are desired. previously manufactured).
- Said release means (8) may correspond to protrusions or cavities arranged in the engagement means (6) to allow, by means of a screwdriver (or the like), an release lever can be exerted that does not involve an over tightening of the connection elements (pipe, fitting and clamp). To achieve the latter (not to exert an over tightening) the force exerted by the lever must be ideally perpendicular to the forces that are reciprocally exerted between the hooks (by action and reaction) when they are in a hooked condition.
- system may include stop means (9) that are arranged so as to limit the displacement of the hook means (6) in order to prevent the clamp (3) from exerting excessive clamping force while being engaged. .
- Said coupling means (6) can be defined by two hooks arranged in said curved walls (4), which allows relatively low manufacturing costs to be involved.
- Said stop means (9) can be defined by two surfaces that rest against or are in close proximity to said hooks when they are in their engaged position, which allows relatively low manufacturing costs to be involved.
- Said hooks can be arranged in proximity to two respective walls that are oriented in opposite directions and that can be pressed against each other by a force (F) to allow the hooking of said hooks, all of which it allows said hooking means to be hooked with the help of a very low cost tool such as a plier or the like.
- Said fitting (2) can comprise a mouth, connected with said pipe (1), defined by a cylindrical region (10) with annular outlets (11) in its outer wall.
- This fitting configuration corresponds to the configuration used par excellence in PEX pipes and when used with the clamp of the invention an extremely firm anchorage is achieved since the annular flange (7) of the clamp (3) acts in addition to the annular outlets (11) from the fitting mouth.
- Said curved walls (4) can include an annular reinforcement flange (12) disposed on the respective outer surface thereof, all of which allows reinforcing the structure of the clamp (3) of the invention minimizing the use of material.
- Said clamp (3) can be manufactured from a polymeric material with the purpose of reducing manufacturing costs.
- Said annular flange (7) may have a triangular cross section for the purpose of concentrating the clamping force in a small region.
