Description

Gate valve with board with wheels.

OBJECT OF THE INVENTION

It is an object of the present invention, as the title of the invention establishes, a gate valve with a board with wheels, a valve comprising a mechanical device with which the circulation (passage) of liquids or gases can be started, stopped or regulated by a movable part that opens, closes or partially obstructs one or more holes

or ducts, where in this case the movable piece is a board that has among other particularities the fact of having rolling means at its edges.

The present invention characterizes the special configuration and design of each of the parts and parts thereof that are part of the gate valve with wheel board, so that a valve is achieved in which the closure or obstruction piece is barely It presents friction, does not imply any loss of load when it is open, where it also improves the opening and closing efforts, avoiding disturbances and modifications of the flow of the fluid.

Therefore, the present invention is circumscribed within the scope of the means for controlling and regulating the flow, and particularly within the scope of the gates and valves.

BACKGROUND OF THE INVENTION

Different means of control and regulation of the circulation of a fluid through a medium are known in the state of the art, such as those described below:

-

Wagon gates that are designed for closures or seals of large sections in holes and channels and with high water loads. The main feature is the rolling system on the sides, which decreases the pressures on the board when sliding. It consists of a welded board with rubber gaskets that act as a seal. These joints can be on three or four sides (two sides, solera and lintel). The sliding takes place by means of a system of rollers that roll guided on a fixed frame embedded in the concrete. This type of floodgates presents as operating characteristics

i. metal-rubber closure.

ii. Rectangular section

iii. It lacks body.

iv.

It does not have recatas.

v.

Low travel efforts

-

Bureau Gate Valves, They are installed in sockets and drains of funds. Normally two are installed by conduit, a first normally open safety and a second regulation. A reinforced frame is formed forming a box; Inside this frame there is a sliding board that performs the shutter function. This board is operated by a hydraulic cylinder, which performs the function of opening and closing, ensuring a thrust in the hearth. The seats and guides are metallic and are designed for an extended and maintenance-free duration. This type of floodgates presents as operating characteristics

i. Metal-metal closure

ii. Rectangular section

iii. Side rails resulting in loss of loads

iv. It requires high travel efforts.

-

Ring-follower gate valve that installs in sockets and drains of drains of funds subjected to large loads, where the speeds of passage through the ducts are very high. A BUREAU gate installed in these ducts would produce significant cavitation effects and disturbances in the lateral gaps and even severe depressions in the housing chambers. With this type of gate (ring-follower) these effects would not occur. A reinforced frame is formed forming a box; Inside this frame there is a sliding board that performs the shutter function. The board in its lower part has a hole with the diameter of the duct. When the board remains lowered, the water remains sealed. When the board rises, it provides continuity in the pipe, which guarantees a regular discharge without disturbances. This board is operated by a hydraulic cylinder, which performs the function of opening and closing. The seats and guides are metallic and are designed for an extended and maintenance-free duration. However, the lower chamber requires that it be equipped with a cleaning pipe for sludge, sand and other sediments. Which presents as characteristics:

i. Metal-metal

ii. Circular section

iii. It does not present demure.

iv. High travel efforts

All these types of gate have their advantages and disadvantages, thus, the wagon gate has significant load losses, while the ring-follower gate or valve presents, among other aspects susceptible to improvement, significant friction, in addition, the requirements are quite high energy to move the board, which is important in emergency situations, such as when there is no energy supply, also, this type of gate is capable of improving the loss of load. In both types of gate the closure is not waterproof.

Another drawback presented by the ring-follower gates, is its constructive complexity, since they require high levels of precision in machining, not being able to be mounted on site, and also can only close in one direction, although the latter could be achieved It would make the valve more expensive by having to machine on both sides of the gate.

Therefore, it is the object of the present invention to develop a closing mechanism, particularly a gate valve, in which:

-

the energy requirements for its displacement, particularly in emergency situations, are the smallest possible,

-

where the losses of load are avoided, by the modifications and disturbances that could be caused to the fluid in its course,

-

the closure is tight,

-

that the valve assembly can be modular, being able to be mounted “in situ”.

-

That is able to offer closure in both directions.

-

And that presents the characteristics of:

-

Metal-rubber closure

-

Circular section

-

incorporates a body

-

It has wheels

-

Low travel effort

-

It does not present recalls, so there is no loss of load.

In order to achieve the aforementioned purposes, a valve such as the one described below has been developed and is essentially included in the first claim.

DESCRIPTION OF THE INVENTION

The object of the invention is a gate valve with dashboard with rolling means, preferably arranged at its edges.

The valve has a valve body, essentially parallelepipedic, which has two faces facing each other parallel and joined together by its lateral edges defining a closed space through which an opening and closing board runs.

The board has one of its halves, preferably the lower one, with an opening, while the upper one has a rubber gasket, preferably made of synthetic rubber.

The shape of the rubber rubber gasket is such that it surrounds the opening made on the main faces of the valve body, being arranged on said main faces and on its inner face with a plate on which the rubber gasket closes, achieving a Watertight closure without any loss.

The rolling means with which the board has can be wheels or rockers, are arranged on the side edges of the board, in number of 4 or 6, and may even be a different number, particularly if rockers are used. Said rolling means run through guides made and mounted on the ends of the interior space defined inside the valve.

Thanks to the characteristics described, it is possible, on the one hand, to ensure that the board can be lifted and lowered with very little energy, by having rolling means, which avoid friction as happens in the ringfollower gates, so even in the In case of lack of energy supply, the closure of the valve could be achieved by the weight of the board itself, serving as an emergency closure.

On the other hand, by having an annular regrowth at the edge of the board perforation and on both sides, there is no significant loss of load. In addition, thanks to the presence of a synthetic rubber rubber gasket, which closes on a plate arranged on the inner face of the main faces of the board, a tight seal is achieved. It is also possible that the valve can close in both directions, and its installation on site is possible directly.

PREFERRED EMBODIMENT OF THE INVENTION.

In view of the figures, a preferred embodiment of the proposed invention is described below.

In Figure 1 we can see the representation of the valve object of the invention, which in the represented position is open. Counting the valve with a valve body (1), inside which a board (2) is housed (figure 2) which has a means of rolling, or rolling, preferably arranged at the edges of the board.

The body (1) of the valve is essentially parallelepiped, presenting two flat faces or surfaces separated from each other and joined together by the four lateral edges, defining a closed interior space through which a closing board (2) runs. In addition, each of the main faces has a hole (2.1) facing each other.

In figure 2, the board (2) is observed, which has an opening (2.1) arranged in one of its halves, either the lower half, or the upper half, preferably in its lower half. Said opening (2.1) has an annular recess (2.2) at the edge thereof, so as to approach, without contacting the opening (1.1) made on both sides of the valve body.

In addition, the board (1) has rolling means (2.3) arranged on the edges of the board, which run along guides (1.2) (figure 3) arranged inside the body (1) of the valve .

The board (2) has a rubber gasket (2.4), arranged in the area not occupied by the perforation (2.1) and where said rubber gasket is preferably made of synthetic rubber or EPDM, with a desired profile, by example of omega, such that it contacts the inner face of the valve body.

The rubber seal (2.4) has a circular shape of dimensions greater than that of the opening (1.1) in order to make a tight seal on the outer edge of the opening (1.1).

In the upper part of the board (2), we can observe a fixing area (2.5) to fix a hydraulic piston of displacement of the board.

In figure 3, it can be seen how the board (2) runs through the interior space of the body (1) of the valve, thanks to the rolling means or wheels (2.3) that run through guides (1.2).

It is worth noting that, on the inside of the two sheets that we could consider, they form the valve body, and next to the edge of the connection opening (1.1), a plate (1.3) is arranged and on which it closes so the rubber seal (2.4) of the board (2) is sealed.

The plate (1.3) has the free or outermost edge arranged in a chamfered manner, so that the rubber gasket (2.4) of the board (2) does not suffer as the rubber gasket (2.4) advances and positions, over the entire plate .

In figure 4, it can be seen how the board (2) when being in position such that it closes the valve, the rubber seal

(2.4) is positioned and pressed on the plate (1.3), which is on the edge of the perforation (1.1) on each sheet that forms the valve body.

5 In Figure 5, the hydraulic piston (3) for lifting and lowering the board (2) can be seen in section. The board drive piston can be inside or outside the board.

In figures 6 and 7, the different positioning of the panel (2) is shown depending on whether the valve is open (figure 7) or closed (figure 6), showing in both cases, the plate (1.3) that would be on the inner face decade

10 side that forms the valve body. Thus, in figure 6, said plate (1.3) would be positioned against the rubber seal (2.4) of the board, while in figure 7, it would be around the opening (2.1) of the board.

As it has been observed throughout all the figures, the body of the valves is manufactured from electro-welded structures of profiles and sheets, which lightens their overall weight without diminishing their resistance at all.

On the other hand, the composition of the board that can be solid or formed of electro-welded structures of profiles and sheets.

Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is noted that, within its essentiality, it may be implemented in other embodiments that differ in

20 detail of that indicated by way of example, and to which it will also achieve the protection sought, provided that it does not alter, change or modify its fundamental principle.

 2. Statement motivated according to articles 29.6 and 29.7 of the Regulations for the execution of Law 11/1986, of March 20, on Patents on novelty and inventive activity; quotes and explanations in support of this statement D01 is considered the state of the art document closest to the object of the request. Hereinafter, the terminology used in the claims of the application will be used. Document D01 discloses (references in brackets correspond to D01) a gate valve with board (10) with wheels (figure 2), comprising a valve body (11) in the form of a parallelepiped, with two flat surfaces separated from each other and joined by the four lateral edges, each of the two flat surfaces including an opening (13), both openings facing each other with respect to each other (column 3, lines 11, 14). Inside the valve body, an opening and closing panel (14) is moved (column 3, lines 16, 20), by means of wheels that run through guides housed in the interior space of the valve body (column 4, lines 23, 41; figure 2). Said board comprises a circular opening (16) and sealing means (15, 19) of circular shape, in order to make a tight seal over the opening of the valve body (column 3, lines 20, 26). Claims 1, 2. The object of claims 1 and 2 has been disclosed identically in document D01 and therefore claims 1 and 2 would not meet the requirement of novelty (art. 6.1 LP 11/1986). Dependent claim 4. The difference between what is disclosed in document D01 and claim 4 is that in document D01 it is not explicitly mentioned that the sealing means of the opening and closing board include a rubber seal of a circular shape. The technical effect produced by this difference would be to guarantee the tightness in the closed position of the valve. Bearing in mind that the passage opening (16) and the sealing means (15, 19) of the valve opening and closing panel of document D01 are circular in shape (figure 1); that the fact of using a circular rubber gasket on the board of a gate valve, to guarantee the tightness in a certain also circular passage section, is a practice widely known in the state of the art; and finally, that in document D01 itself the use of a circular joint (17), located in the opening and closing board, is disclosed to ensure that there are no leaks or leaks in the open position of the valve; it is considered that for a person skilled in the art it would have been evident to use a circular rubber seal in the closure section of the board of document D01, to ensure a tight seal over the outer edge of the opening of the valve body in the closed position, thus obtaining a valve as set forth in claim 4, and therefore claim 4 would not meet the inventive activity requirement (art. 8.1 LP 11/1986). Dependent claim 5. The difference between what is disclosed in document D01 and claim 5 is that in document D01 it is not explicitly mentioned that the opening of the board has an annular regrowth at the edge thereof. The technical effect produced by said difference would be to allow the edge of the board opening to approach the valve body and consequently, in an open position, to the openings made on both sides of said valve body. The technical problem that solves this difference would be how to provide a continuity of the flow as it passes through the valve and thus reduce the loss of load. Said problem is widely known in the state of the art and, for example, in document D01, for this purpose, expansion means (18) are used which, when the valve is disposed in the open position, actuate sealing gaskets (17 ) arranged around the opening of the board, in such a way that a connection is established between the passage sections of the fluid in the board and the valve body, guaranteeing the tightness in the flow passage and at the same time avoiding friction in subsequent opening and closing movements, by eliminating, where appropriate, the connection between the passage openings by deactivating the expansion means. The fact of using a regrowth of the edge of the opening of the board is considered an alternative design option that aims to solve the same technical problem and that in the face of the prior art, it would have been an obvious option for a person skilled in the art, for what claim 5 would not meet the requirement of inventive activity (art. 8.1 LP 11/1986). Dependent claims 3, 6-10. Faced with the prior art, they do not include additional or alternative technical characteristics that meet the requirements of art. 8.1 LP 11/1986, so that claims 3, 6, 7, 8, 9 and 10 would not meet the requirement of inventive activity (art. 8.1 LP 11/1986).
