Description

TECHNICAL FIELD

The invention relates to a dual-safety gas valve with body manufactured by employing aluminum extrusion method and designed for use at the domestic cookers. Said gas valve can be manufactured either as dual- or single-outlet valves. More energy is consumed due to use of the brass materials at the bodys of the cooker gas valves made of brass material via forging method as brass materials are heavier than other raw materials and are harder to process. Moreover, the valve manufacturers tend towards seeking more economic and also lighter, more robust, more efficient and more durable materials as brass materials are more expensive than others as raw material. As a result of such search, aluminum raw materials, which are cheaper and lighter than the brass materials, are preferred.
The valves used today provide gas flow at desired flow rate, thus enable the user to achieve combustion that conform to the desired power at the burner. In the valve design, however, factors such as size, weight, ease of production, cost, etc. should also be taken into account in addition to the function. Therefore, distinct designs emerge constantly at the point of optimizing all such factors. The dual-safety gas valve of the invention with body manufactured by employing aluminum extrusion method possesses an innovative design at it incorporates said functions. High tonnage press is employed at the forging operations, which is another method used in the state of the art and additional time, energy and labor is required for removing the burrs from the body so produced. Using extrusion method in production of the valve body not only saves from energy and time in production, but also adds desired hardness and machinability characteristics to the body.

DETAILED DESCRIPTION OF THE INVENTION

The perspective view of the dual-safety gas valve (1) of the invention designed for use at the domestic cookers, generally comprising of a safety valve (1.1), a male (1.2), a shaft (1.3), a pin (1.4), an adjusting screw (1.5), a cap (1.6) and a body (1.7) manufactured by employing aluminum extrusion method and fitting screws (1.11) is shown in figure 1. It is also possible to manufacture an alternate configuration of said gas valve (1) as dual-outlet gas valve (2). The perspective view of the dual-outlet gas valve (2) is shown in figure 10.
The body (1.7) of said gas valve (1) of the invention is manufactured from aluminum material as one-piece construct by employing the extrusion method, which is the process of obtaining semi products with length larger than the cross section by extruding the material through a die. Figure 3 and figure 4 illustrates the front and side views of the extruded form of the gas valve (1) body (1.7) of the invention, respectively. The widest width (1.7.1) of said body (1.7) is in the range of 15-20 mm, the widest length (1.7.2) is in the range of 55-60 mm, and the widest height (1.7.3) is in the range of 35-40 mm.
The gas valve (1) body (1.7) of the invention generally comprises of a gas inlet (1.7.4), a gas outlet (1.7.5), a male housing (1.7.6), an adjusting screw housing (1.7.7) and safety valve housing (1.7.8) positioned either above or below the body in such manner to extend parallel to the gas outlet (1.7.5). The dual-outlet gas valve (2) in the alternate configuration, on the other hand, contains safety valve housing (1.7.8) and a second gas outlet (2.1) positioned parallel to the gas outlet (1.7.5), and is designed in such manner to enable use of a single or multiple adjusting screws (1.5). Moreover, the safety valve housing (1.7.8), the gas outlet (1.7.5) and the second gas outlet (2.1) are designed so as to allow use of internal threaded coupling in both valve designs. By virtue of using internal threaded safety valve coupling (1.8) and the gas outlet coupling (1.9), the size of the gas valve is reduced, thus allowing introduction of a gas valve (1) with narrow configuration. The gas entering the body (1.7) via the gas inlet (1.7.4) as the shaft (1.3) is pushed comes first to the safety valve (1.1), and then reaches to the gas outlet (1.7.5) by passing through the combustion holes on the male (1.2) that rotates as the shaft (1.3) is rotated. Primary safety at the gas valve (1) and the dual-outlet gas valve (2) of the invention is ensured by means of the safety valve (1.1), while secondary safety is ensured by not allowing the gas to flow from the male (1.2) if the shaft (1.3) is not rotated. At the position where the gas valve (1) is fully open, the gas reaches to the gas outlet (1.7.5) directly from the main gas passage groove (1.7.9); at the minimum combustion position, on the other hand, the gas reaches to the gas outlet (1.7.5) from the main gas passage groove (1.7.9) after passing from the adjusting screw housing (1.7.7). the gas passage grooves at the gas valve body in the state of the art are drilled by employing machining method and closed with a ball. This method, however, is a disadvantageous method as the material is directly scraped in case of any problem during production. At the gas valve (1) of the invention, on the other hand, the main gas passage groove (1.7.9) within the body (1.7) can be drilled directly during production of the body (1.7). Furthermore, there is a gasket (1.10) available in order to ensure sealing at gas inlet (1.7.4) section and it is possible to identify whether the gas valve (1) is mounted to the gas distribution pipe (3) smoothly by means of the hole (1.7.10) drilled on the body (1.7).
