Abstract

Mangon for guillotine valves, of the type that have a flattened valve body in whose bosom plays a sliding gate by any means, incorporating two rubber sleeves, reinforced with a steel core, and moving the chopper between both hubs and in counting the elastic deformation thereof, characterized in that it incorporates a tubular and practicable body, whose hollow interior (8) enhances its flexibility especially against chocks (3) of considerable thickness.

Description

Handle for guillotine valves.

Object of the invention

The present invention relates to a sleeve, it is tell the closing ring that, with the collaboration of another identical and opposed, determine the closure for the chopping board of a guillotine valve

The object of the invention is to achieve a sleeve elastomeric metal core, which offers minimal friction for the chopping board, and that thanks to greater flexibility is keep in mutual contact when the chopping board is in inoperative situation (valve open), and open or flex duly when said chopping board adopts the operating situation (valve closed) in which it is located between both hoses.

Background of the invention

As is known, in a guillotine valve establishes a body, usually cast, substantially flat, in whose breast the chopping board, shutter or closing element, which is operable by means of a cylinder hydraulic or pneumatic, an electric motor, a steering wheel manual operation, or by other means.

In the aforementioned body a seat is established for the chopping board, which is made up of two mangones that usually, and To offer high strength and durability, they are manufactured to base of elastomeric material, that is rubber with a soul of stainless steel.

Depending on the expected working pressure for the valve, the chopping board must be of greater or lesser thickness, of so that when the thickness of said chopping board is considerable the valve actuation is hindered by friction of the chopping board with the mangones, because the latter are massifs and, consequently, with little flexibility or ability to deformation.

Description of the invention

The sleeve for guillotine valves that the proposed invention resolves in a fully satisfactory manner the problematic previously exposed, offering a high degree of flexibility and, maintaining an optimal situation of mutual contact and direct between hoses when the valve is open, being able to separate easily, that is, with an effort minimum by the valve actuation means, during the chopping movement of the chopping board towards the situation operant or closing.

To do this, more specifically and in agreement with one of the characteristics of the invention, the sleeve that is advocates, starting with the classic combination of a body elastomeric and a soul of stainless steel, centers its characteristics in the fact that said body is hollow, so that the elastomeric material deforms more easily towards the inside of said hole.

According to another of the characteristics of the invention is provided that the hollow interior of the body of the sleeve be accessible from the outside, specifically through your face opposite to the contact between mangones, by means of a series of openings located in the wall equivalent to said cover and that they are closed by means of corresponding plugs, like tacos tightly attachable to the interior access holes as well same hollow of the body of the mangón.

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, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Preferred Embodiment of the Invention

As just said, in figure 1 it has been represented a guillotine valve to which the sleeve of the invention, valve constituted by a body (1), flattened, with a wide circular hole (2) to which they are attachable two sections of coaxial and contraposition pipe, this being hole (2) sealed by means of a chopping board (3) operated by for example, by a cylinder (4) or by any other appropriate means, chopping board (3) which, as seen in Figure 2, is destined to be located in a closed situation between a couple of coaxial and facing hoses (5-5 ').

These mangones (5-5 ') have a body provided with a perimeter step (6) through the that are coupled to the two constituent parts of the valve body (1), being obtained based on an elastomeric material and have also, as is conventional, with a metal core (7) that stiffens the sleeve and prevents it from becoming deformed when the chopping board (3) it crosses the defined gap between the two mangones in its download process, as shown in figure 3.

Well, according to the invention, the body (5) of the mangones is hollow, presenting a wide emptying inside (8), but being closed outside.

The body (5) of the sleeve adopts a tubular configuration, but is endowed on its opposite side to that of adaptation to the chopping board (3), of a plurality of holes or openings (13) for access to its hollow or hollow interior (8), which they close by means of plugs (14) that can be fitted in said gaps (13).

The hollow interior (8) of the sleeve is stiffened by means of transverse partitions (15) to enhance their mechanical resistance, and are provided with outer ribs (16), which in their case also affect the plugs (14) and that improve the tightness of the sleeves with respect to the valve body (one).

The described device has a structure optimized, with a volume of emptying in the sleeve proportional to the valve passage section.

Claims (4)

1. Handle for guillotine valves, of the type that have a flattened valve body in whose breast a chopping board plays by any means, incorporating into the body two rubber sleeves, reinforced with a steel core, and moving the chopping board between both mangones and in counting of the elastic deformation of the same, characterized in that it incorporates a tubular and practicable body, whose hollow interior (8) enhances its flexibility especially against chopping boards (3) of considerable thickness. 2. Handle for guillotine valves, according to claim 1, characterized in that a plurality of transverse partitions (15) are established in the hollow interior of its body. 3. Handle for guillotine valves, according to claims 1 and 2, characterized in that the hollow interior (8) of its body (5) is practicable through a plurality of openings (13), open towards its opposite side to the adaptation to the chopping board and which is closed by means of plugs (14) that fit tightly in said holes (13). 4. Handle for guillotine valves, according to previous claims, characterized in that its body (5) incorporates ribs (16) for adaptation to the constituent parts of the valve body, which enhance the seal on the latter.
