Description

DESCRIPTION

Filtering nozzle with self-locking system of retractable walls and with external actuator.

Object of the Invention

The present Utility Model refers to a filtering nozzle composed of a tube, called a plug, which is inserted in the hole of a plate and has a cap with grooves in the part that remains outside and a fixing system by folding the walls of the block in the part remaining inside the plate.

When the water penetrates from outside the plate and through the lid with slots, the device can act as a filtering nozzle for particles and materials.

When the water comes out from the inside of the plate through the plug and the slots, it forms a shower allowing also the cleaning of the slots.

The device also allows the free circulation of air in both directions.

The self-fixing system is by folding the walls of the block inside the plate. Said process is operated from the outside by means of a screw that goes through the whole device and that is screwed to the end of the plug.

BACKGROUND OF THE INVENTION

Filtering or crepine nozzles are devices that are manually inserted and screwed onto a plate or on the walls of pipes to filter the passage of water or allow air to escape.

They basically consist of a hollow tube with a filtering head on one end and a thread on the other end.

In filtration mode the water enters through the filtering head and exits through the part with the thread.

In counter-wash mode the flow reverses and the water enters through the threaded part and exits through the filtering head in the form of a shower, thus allowing cleaning of the grooves.

To operate the filter nozzle, a part of the threaded pipe is inserted into the hole of a plate, so that the threaded pipe protrudes from the inside of the surface.

Normally, the filter nozzle is attached to the plate from the inside with a nut.

There are also filter nozzles that can be fixed from the outside of the plate.

In these cases, the tube has walls in the form of attached petals that open to the sides inside the surface when the head of the filter nozzle breaks the stops that hold them straight, thus allowing the self-fixing of the piece.

Filtering nozzles equipped with self-fixing systems existing on the market are complex and fragile structure devices formed by several interlaced pieces which forces them to manufacture them of a certain size and at a high cost.

On the other hand filter nozzles equipped with self-fixing systems in the market require a long tube so they need space inside the plate in order to enable the opening of the fixing system.

It should also be mentioned that the filter nozzles equipped with self-fixing systems on the market are not easily uninstalled since once the petals are opened, or any other similar system inside the plate, the mechanical stops that hold the petals are broken. which is not easy to retract them.

Novelty

There are currently no filtering nozzles in the market that have a self-fixing system incorporated on the basis of retractable walls that allow their installation in small spaces and that are simple to manufacture and low cost.

It should be said, therefore, that so far has not been achieved a design for a filtering nozzle that may be small and with a built-in self-fixing system that allows to be installed and uninstalled easily and without special machinery and in areas of difficult access, both inside and outside the surface where it will be installed.

Description of the invention

The device is formed by three pieces that fit together.

The pieces are: a hollow plug or tube, a cap with micro-slots and an actuator screw that crosses both parts from the outside to the bottom of the plug where it is screwed.

The block has two different sections and of different diameter, one for the part that remains outside and another for the inside.

The cap with micro-grooves is screwed to the outside of the block.

The cap has a hole in the center through which an actuator screw is inserted.

The actuator screw goes through the entire end-to-end block and is screwed into an internal thread at the end of the block.

The walls of the inner section of the block are cut on both sides and along the block but joined at both ends, in such a way that they form two parallel walls and separated by a hollow space without a wall.

Said parallel walls are designed in such a way that they are forced to fold when the actuator screw retracts the end of the plug.

The bent walls fix the device inside the plate and can act as a mini-nozzle.

By inverting the direction of rotation of the actuator screw the walls are returned to their original position and the device can be removed from the hole.

The number and diameter of the micro-slots of the nozzle cap is defined according to the flow rate required by the mini-nozzle.

The interior of the mini-nozzle is designed in such a way that they allow the passage of a sufficient flow of water to allow the washing of the micro-grooves from the inside.

This mini-nozzle also allows the flow of air in both directions since it does not have any type of valve or system that prevents or hinders it.

In order to better understand the scope of the invention, object of the present Utility Model, the attached drawings are presented in which a preferred design thereof has been given, by way of example and without limitation.

The operation of the device object of this invention is described below.

In a first phase the assembly of the 3 pieces described is done as shown in Figure 5.

Next, a hole is made of the diameter of the block to be placed and the block inserted so that the entire lower part is inside the surface.

Then start to screw the actuator screw which causes the wings of the plug to retract.

They thus press against the interior walls of the surface.

Once adjusted the plug can be put to work so that water or air passes as desired.

For the flow from the outside to the inside of the surface where the device has been inserted: the water passes through the surface of the cap through the micro-slots, then passes to the inner chamber of the plug and finally exits through the inside of the chamber. the surface through two holes located in the base of the plug on both sides of the actuator screw.

For the case of water flow from the inside to the outside, the flow penetrates through the two holes in the base of the plug, passes to the inner chamber of the head of the plug and finally comes out equally through all the micro-slots of the cap of the cue and in the form of a shower.

Within the essence of the invention there is a variant of detail, likewise protected, and thus the characteristics of the different heights may vary, the adaptation of the base of the block to a curved surface, shape and diameter of the pieces and couplings, size and location of the micro-slots, as well as the holes of the base, types of retractable wings, type of material and, of course, any of the dimensions, colors and materials with which it is made.
