ALUMINUM PROFILE GAS VALVE

Description

TECHNICAL FIELD

[0001] The invention relates to a double safety gas valve with body manufactured by employing aluminum extrusion method and designed for use at the domestic ovens. 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.

[0002] 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 double 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.

PRIOR ART

[0003] Patent application no. CN103537506 (A) by ZHANGJIAGANG HAOTIAN METAL SCIENCE & TECHNOLOGY CO. LTD., mentions the manufacturing process for solid aluminum profile by means of extrusion method. The application contains process steps such as identifying the size and shape of the aluminum profile in step S1; choosing the device based on requirements between the processes in step S2; calculating the extrusion force of the aluminum profile via extrusion contraction method in step S3, and calculating the dimensions of the die and the pieces, the inner dimensions of the die, the tip surface of the die and the length of the tape in the form of a hole thereon in step S4. The production method of the solid aluminum profile extrusion die is simple and extrusion efficiency is high. Said application, however, relates only to the steps of use for the extrusion method, and said method has been preferred in the invention that we filed an application as it saves from time and labor, improves efficiency and is easy to process.

[0004] The patent application no. US2002641 A by THOMPSON PROD INC. relates to a valve with a shaft section and a cap section manufactured via composite metal forming method. The subject matter of said application is fixing of the cap and the shaft sections of the valve made of different metallic substances. Said application relates to completion of the valve as a result of joining the cap and the shaft made of different metallic raw materials via welding, and share similarity with the subject matter of the invention again in terms of the extrusion method employed here, but differs from our invention as there is no mention of the valve made of an aluminum profile used at domestic cookers.

[0005] A gas valve according to the preamble of claim 1 is described by EP2615371. f

[0006] In the light of the prior art mentioned above, producing one-piece body of the safe oven valves with safety valve used at the domestic cookers from aluminum material via extrusion method is an innovative practice. This invention also exceeded the state of the art as it solves the problems in the state of the art and can be used conveniently at the gas valves used for domestic cookers in the industry.

AIM OF THE INVENTION

[0007] The aim of the invention is to introduce a gas valve with double safety, dual-outlet and narrow configuration with a body manufactured via aluminum extrusion method in order to be used at the domestic ovens.

[0008] The aim of the invention is to introduce a gas valve design that enables use of single or multiple adjusting screws.

[0009] Another aim of the invention is to be able to reduce the size of the gas valve by using internal threaded coupling at the safety valve and gas outlet sections.

[0010] Another aim of the invention is to enable manufacture of the gas passage grooves within the body directly during production of the body.

[0011] Another aim of the invention is to is to be able to position the gas outlet either above or below in such manner to extend parallel to the safety valve.

[0012] Another aim of the invention is the use of zamak injection method in production of the cap, shaft and pin of the gas valve.

DETAILED DESCRIPTION

[0017] The perspective view of the single outlet double safety gas valve (1) which is not part of the invention designed for use at the domestic ovens, 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. The present invention teaches to manufacture said gas valve (1) as dual-outlet double safety gas valve (2). The perspective view of the dual-outlet double safety gas valve (2) is shown in figure 10.

[0018] The body (1.7) of said gas valve (1) 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) 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 tallest height (1.7.3) is in the range of 35-40 mm.

[0019] The gas valve (1) body (1.7) 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 double safety gas valve (2) of the invention 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 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 double safety 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 outlet hole (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 outlet hole (1.7.9) after passing from the adjusting screw housing (1.7.7).

[0020] 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 outlet hole (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).
