DESCRIPTION

Progressive flow gas valve

technical field

The invention refers to double safety domestic gas valves that work together with a motor and a solenoid coil that can be activated with an electronic circuit, where there is a male that is used in gas quantity regulation tasks. that happens and that provides a gradual throttling of the fire as different from the current condition. Additionally, there are at least two gas passage channels in relation to the plug of the gas valve body and the gas passage is provided by rotating said plug placed in this body. In addition, the alternative double outlet structure of the gas valve object of the invention was designed to be used in burners with multiple combustion circles. Accordingly, a gas valve with an alternative structure comprises a plug and a body with an alternative structure.

There are combustion holes of different sizes from each other in the plug found in manually controlled gas valves in the current condition and the gas reaches the burner by passing through these holes. The gas flow is regulated depending on the diameter size of the combustion hole through which the gas passes. Therefore, the cooker can be operated fully open or in the lowered position. However, the gas burner cannot be scaled down and a smooth transition between flame volumes cannot be provided in current gas valves since the gas passageway faces either of the two combustion ports at the same time. same time and then hits a burning hole when the plug is turned, causing a sudden flare of fire. The plug object of the invention is designed to be used in gas valves controlled by contact, where the burner can be progressively reduced by means of the ducts that the plug comprises.

The gas valve in which the plug with grooves that is the object of the invention is positioned is made of brass or aluminum, like the present gas valves. Because these materials are durable under the conditions of tests and experiments specified in standards EN 1106, EN 125, EN 126, etc. Each gas valve manufacturer applies these gas valves to the tests specified in these standards. The safety and reliability of the product are determined based on these tests. The plug that is the object of the invention is produced by the machining method from aluminum or brass material.

prior art

Document US2013260327, which can be considered to represent the most pertinent state of the art, describes a valve comprising a plug provided with slots and holes for maximum and minimum flow adjustments, which is adjustable for use with NG and LPG. A further related valve is described in European patent application EP2827060 A1, which describes a motor-driven gas valve comprising a plug provided with a slot and with holes for control of the flow of combustion gas.

Another application with number PI 8500156 dated 01.14.1985 owned by Adolfo de Mitry refers to ovens that work with gas and the gas valve that opens and closes the passage of gas in their lighters and regulates the amount of gas between them. . The closure of said valve is by means of an elastic disk that functions to supply gas from its center either at higher or lower levels by virtue of the closure of a metallic center, thus eventually allowing the flame to be supplied in high or low quantities. .

In said application a threaded globe valve has been used manufactured in such a way as to allow adjustment of the inner section of the center and said center has been equipped with a hole designating the opening and closing of the valve. No metal is used in the inner sphere of the center of the elastic cap to provide a solution to the discomfort arising from this gas valve comprising a tapered shaft. Consequently, our invention in question is also a different application than this application.

In light of the aforementioned prior art, the availability of slots as specified in the claims in the plug of gas valves of domestic gas-operated kitchens that allow the flow of gas is an innovative practice. This invention has surpassed the prior art in that it provides a solution to the problems of the prior art.

Purpose of the invention

The purpose of the invention is to introduce a double safety gas valve that contains a plug different from the plugs of the state of the art.

Another object of the invention is to have slots in the plug that are interconnected with the holes that allow the passage of gas in the gas valve.

Yet another object of the invention is to have at least two gas passage slots interconnected with the slots in the plug of the gas valve body.

Another object of the invention is to allow gradual adjustment of the fully open or fully closed position of the cooker. Another objective of the invention is to introduce a gas valve in an alternative configuration with a double outlet and a plug in an alternative configuration in compliance therewith.

Yet another object of the invention is to design the gas passage slot in the single outlet gas valve body in an alternate configuration such that it sees the full combustion port and the slot merged with the full combustion port; while designing the cross gas passage slot to see the NG and LPG pilot holes and the slots attached to said pilot holes.

Detailed description of the invention

The invention refers to a double safety gas valve that operates together with a motor and a solenoid coil that can be actuated with an electronic circuit in domestic kitchens, and said gas valve (1) basically contains a plug (1.2) and a body (1.1) that houses a gas passage slot (1.1.1) and a crossed gas passage slot (1.1.2) interconnected with said male (1.2). Once the user enters the desired command to the touch button on said gas valve (1), the motor rotates according to the data sent to the electronic card and said rotation movement thus ensures the orientation of the gas passage since said Movement is transferred to the male (1.2) placed on the gas valve (1) by means of the motor gears. The plug (1.2) of the gas valve (1) of the invention contains, unlike the plug in the current states (2), a complete combustion hole (1.2.1) instead of multiple combustion holes (2.1) , one NG pilot hole, one LPG pilot hole (1.2.3), one slot attached to NG pilot hole (1.2.2.1), and one slot attached to LPG pilot hole (1.2.3.1).

In the gas valves of the current state, since the gas passage slot coincides with any two combustion holes (2.1) simultaneously and then reaches a single combustion hole (2.1) when the plug (2) is turned, the burner of gas cannot be turned downwards gradually, thus avoiding reaching a homogeneous transition between the flame intensities. This, in turn, leads to an instant deflagration of the flame. By virtue of the triangular slot attached to the complete combustion hole (1.2.1.1) available in the plug (1.2) of the invention, on the other hand, it not only allows the gradual reduction of the flame slowly, but also prevents the deflagration of the flame. The body (1.1) of the gas valve (1) is also redesigned according to the current state in compliance with the plug (1.2) of the invention. Consequently, there are multiple gas outlet slots in the body (1.1). At the same time, transformation of LPG or natural gas is also possible by virtue of the software depending on the return of the core (1.2). The gas burner can be made suitable for use with natural gas as the transverse gas passage slot (1.1.2) sees the slots (1.2.3.1) associated with the NG pilot orifice (1.2.2) and the orifice LPG pilot; and for use with LPG as you only see the LPG pilot port (1.2.3.1).

After the gas inlet from the gas inlet (1.1.3) and as the inlet allows gas flow from the rotating plug (1.2) through the rotating movement driven by the motor, the gas flows from the combustion hole (1.2.1) in the male (1.2) up to the gas passage slot (1.1.1) and reaches the gas outlet (1.1.4), thus initiating the complete combustion of the gas burner. The connection of the gas passage slot (1.1.1) with the complete combustion hole (1.2.1) can be seen in Figure 10. As the plug (1.2) rotates, the gas flows from the triangular slot attached with the complete combustion hole (1.2.1.1) towards the gas passage slot (1.1.1) and the intensity of the flame is slowly reduced as its structure shrinks due to such a triangular shape. The transverse gas passage slot (1.1.2) in the body (1.1), on the other hand, is positioned to see the slots connected with the NG and LPG pilot holes (1.2.2.1 and 1.2.3.1). In this way, from the moment the plug (1.2) begins to rotate, the gas flows through the slot connected to the GN pilot hole (1.2.1.1), and through the slot connected to the LPG pilot hole (1.2.3.1). after a certain position of the male (1.2), thus avoiding flame deflagrations such as those experienced in the current state. The minimum gas flow is provided when the rotation of the plug (1.2) inside the gas valve (1) is completed, and the gas burner burns at the lowest level, and at this stage, for NG, the gas flows from the slot joined with the NG pilot hole (1.2.2) and the LPG pilot hole (1.2.3.1) to the transverse gas passage slot (1.1.2) and reaches the gas outlet (1.1.4). At this stage, for LPG, on the other hand, the gas flows from the LPG pilot hole (1.2.3) towards the transverse gas passage slot (1.1.2) and reaches the gas outlet (1.1.4). These angles in said male (1.2) that allow reaching such positions where the maximum and minimum combustions are achieved and that are illustrated in Figure 6 in cross sections FF, GG and HH in the male (1.2) are the angle "a " (1.2.1.2), angle "b" (1.2.2.2) and angle "c" (1.2.3.2), and their values are described below: The angle "a" (1.2.1.2) between the slot linked to the full combustion orifice (1.2.1.1) that allows maximum combustion in the plug (1.2) and the complete combustion orifice (1.2.1) is in the range of 90° to 140°; the angle "b" (1.2.2.2) between the slot attached to the GN pilot hole (1.2.2.1) and the GN pilot hole (1.2.2) that allows minimum combustion when using GN gas in the range of 90° to 140°; and the angle "c" (1.2.3.2) between the slot attached to the LPG pilot hole (1.2.3.1) and the LPG pilot hole (1.2.3) that allows minimum combustion when using LPG gas in the range of 90° at 140°.

In addition to the above, an alternate configuration with a double outlet of the gas valve (1) of the intake and the male in alternate configuration (3.2) has been designed for use in said configuration with the purpose of controlling the passage of gas in the burners with multiple combustion rings.

The body of the gas valve (3) in alternate configuration contains a gas inlet (3.1.7), a first gas outlet (3.1.1), a second gas outlet (3.1.3), a passage slot of the inner ring (3.1.2), a transverse gas passage groove of the inner ring (3.1.3), a gas passage groove of the outer ring (3.1.4) and a second gas passage groove of the outer ring (3.1.6). The male (3.2) in an alternative configuration, on the other hand, contains the inner ring full burn hole (3.2.1), an outer ring full burn hole (3.2.4), an inner ring NG pilot hole (3.2.2), an outer ring NG pilot hole (3.2.5), an inner ring LPG pilot hole (3.2.3) and an outer ring LPG pilot hole (3.2.6), and Figure 14, Figure 15 and Figure 16 illustrate perspective views of the male (3.2) in an alternative configuration.

Consequently, the gas passage in the gas valve (3) in alternating configuration is as follows: the gas from the gas inlet (3.1.7) passes through the complete combustion hole of the inner ring (3.2.1) and the complete combustion hole of the outer ring (3.2.4) in the plug in alternate configuration (3.2) and reaches the first gas outlet (3.1.1) and the second gas outlet (3.1.3). In this way, maximum combustion occurs at the inner and outer ports of the burners with multiple combustion rings. Figure 23 illustrates the plug in an alternative configuration (3.2) in the position of maximum combustion and the location of the inner ring and outer ring gas passage slots (3.1.2, 3.1.3, 3.1.5 and 3.1). .6) in the alternative body (3.1). By rotating the plug (3.2) in an alternative configuration at a certain angle, it is ensured that a certain gas passage slot of the inner ring (3.1.2) sees the complete combustion hole of the inner ring (3.2.1), and the gas passage slot of the inner ring (3.2.1) The outer ring gas passage (3.1.5) sees the outer ring NG pilot hole (3.2.5) and the outer ring LPG pilot groove (3.2.6.1) when using NG gas, and sees the outer ring LPG pilot hole (3.2.6.1). outer ring (3.2.6) when using LPG gas. In this way maximum combustion is achieved on the inner ring and combustion at minimum position is achieved on the outer ring. The view representing this position is illustrated in Figure 24. As the holes that supply gas to the outer ring in the plug (3.2) in an alternative configuration will close when the rotation of the plug (3.2) in an alternative configuration continues at a certain angle , the outer ring ports will move to the closed position while maximum combustion continues at the inner ring ports. Figure 25 illustrates the position of the plug (3.2) in an alternative configuration when the outer ring ports are closed and the inner ring ports are burned in the maximum position. When the plug (3.2) is further rotated in an alternate configuration, there is minimal passage of gas to the inner ring ports from the NG pilot hole of the inner ring (3.2.2) if NG is used, and from the pilot hole Inner ring LPG (3.2.3) if LPG is used. The view representing this position is illustrated in Figure 26. When said plug (3.2) in an alternative configuration is further rotated, as the holes supplying gas to the inner ring in the plug in an alternative configuration (3.2) will close , the inner ring ports will also go to a closed position. Said angles that allow the male in an alternative configuration (3.2) to reach such positions illustrated in Figure 17 in cross sections AA, BB, CC, DD and EE in the male in an alternative configuration (3.2) are the angle 8 (3.2 .1.2), angle a (3.2.2.2), angle p (3.2.3.2), angle ^y (3.2.5.1) and angle 0 (3.2.6.2), and their values are described below: angle 8 (3.2.1.2 ) between the complete combustion hole of the inner ring (3.2.1) and the complete combustion groove (3.2.1.1) in the plug in an alternative configuration (3.2) is in the range of 100° to 140°; the angle a (3.2.1.2) between the pilot hole NG of the inner ring (3.2.2) and the guide groove NG of the inner ring (3.2.2.1) is in the range of 100° to 140°, the angle p (3.2 .3.2) between inner ring LPG pilot hole (3.2.3) and inner ring LPG pilot groove (3.2.3.1) is in the range 90° to 130°, angle Y (3.2.5.1) between the complete combustion hole of the outer ring (3.2.4) and the pilot hole NG of the outer ring (3.2.5) is in the range of 40° to 80°, and the angle 0 (3.2.6.2) between the pilot hole Outer Ring LPG (3.2.6) and Outer Ring LPG Pilot Groove (3.2.61) is in the range of 40° to 80°.

In addition to the above, the gas valve (1) of the invention and the gas valve in an alternative configuration (3) can be connected to the gas distribution pipe (4) either as a single valve or in multiple quantities. These situations can be seen in Figure 27, Figure 28, Figure 29 and Figure 30.
