Explanation of the Invention

The invention relates to gas valves used in gas-fired stoves, which allow the gas path to be turned on and off and to be adjusted gradually. The gas valve subject to the invention consists of body (10), trunnion (20), cap (30) and tail (40).

The body (10) includes first gas outlet (11), second gas outlet (12), third gas outlet

(13), gas inlet (14), low flame adjustment (15). It also includes adjustment holes (16) consisting of the first hole (16.1), the second hole (16.2), the third hole (16.3) and the fourth hole (16.4).

Trunnion (20) includes the first trunnion hole (21.1), the second trunnion hole (21.2), the third trunnion hole (21.3), the fourth trunnion hole (21.4) and the fifth trunnion hole (21.5). In addition, there is a spline (22) and shaft groove (23) on the trunnion (20).

The cap (30) includes the first indicator (31.1), the second indicator (31.2), the third indicator (31.3), the fourth (31.4) and the fifth indicator (31.5). Along with these, there is also a fixing hole (32) on the cap (30).

The body (10) is the main part where the gas inlet (14) is located. The trunnion (20) enters the body (10). After the gas is taken into the body (10) through the gas inlet

(14), its intensity must be adjusted and controlled before it gets into the combustion environment. Said adjustment is made with trunnion (20).

4 The trunnion (20) is rotated by the tail (40). The fixing shaft (41) located on the tail (40) enters the shaft groove (23) located on the trunnion (20). the trunnion (20) is rotated through the fixing shaft (41) entering the shaft groove (23) It is ensured that the desired gas adjustment can be made by rotation. In an alternative embodiment of the invention, the tail can be turned and controlled electronically.

There are signs on the cap (30) showing which gas setting is on-off. The desired gas adjustment can be made by turning the tail (40). There is a recess on the cap (30). When the tail (40) is brought over the indent (33), pressed and waited, the thermocouple is activated and the spark required for combustion is obtained. While the tail (40) is on the indent (33), when said tail (40) is pressed, the tap activates only the pilot gas. In this way, excess gas output is prevented.

The cap (30) is fixed on the body (10). Said fixing process means that the fixing hole (17) on the body (10) and the fixing hole (32) on the cap (30) are fitted with a screw, etc. It is done by combining it with an auxiliary tool.

The adjustment holes (21) located on the trunnion (20) adjusts which gas outlet (11,12,13) the gas from the inlet (14) will come out. It is also provided that the gas can be turned off and adjusted. There are five gas adjustment holes (21) on the trunnion (20), the first trunnion hole (21.1), the second trunnion hole (21.2), the third trunnion hole (21.3), the fourth trunnion hole (21.4) and the fifth trunnion hole (21.5).

On the body (10), there are adjustment holes (21) located on the trunnion (20) and adjustment holes (16) to control and regulate the gas. Said adjustment holes (16) together with the adjustment holes (21) located on the trunnion (20) provide the control and direction of the gas.

There are five different positions on the stove valve, which is the subject of the invention. There are five adjustment indicator (31) signs on the cap (30). These are the first indicator (31.1), the second indicator (31.2), the third indicator (31.3), the

5 fourth indicator (31.4) and the fifth indicator (31.5). The mentioned positions are explained below.

First Position

When the indicator shaft (42) located on the tail (40) is at 0°, that is, when the first indicator (31.1) located on the cap (30) is on, the gas is turned off. Any adjustment hole (21) located on the trunnion (20) in the first position does not coincide with any adjustment hole (16) located in the body (10).

Second Position

When the indicator shaft (42) is rotated 30° clockwise, it coincides with the second indicator (31.2) on the cap (30). The fact that the indicator shaft (42) is on the second indicator (31.2) means that the third gas outlet (13) is open. With this action, the third hole (16.3) on the body (10) is opened. In the second position, the third trunnion hole (slotted hole) (21.3) located on the trunnion (20) corresponds to the third hole (16.3) on the body (10).

Third Position

When the indicator shaft (42) is rotated 90° clockwise, it coincides with the third indicator (31.3) on the cap (30). By turning the trunnion (20) with the third indicator (31.3), it is ensured that the first gas outlet (11), the second gas outlet (12) and the third gas outlet (13) are opened simultaneously. With this action, the first hole

(16.1), the second hole (16.2) and the third hole (16.3) on the body (10) are opened. In the third position, the third trunnion hole (slotted hole) (21.3) located on the trunnion (20) coincide with the third hole (16.3) on the body (10). In addition, the first trunnion hole (21.1) on the trunnion (20) coincides with the first hole (16.1) on the body (10), and the second trunnion hole (21.2) coincides with the second hole

(16.2) on the body (10).

6 Fourth Position

When the indicator shaft (42) is rotated 150° clockwise, it coincides with the fourth indicator (31.4) on the cap (30). By turning the trunnion (20) with the fourth indicator (31.4), it is ensured that the first gas outlet (11) and the third gas outlet (13) are opened steadily. With this action, the first hole (16.1) and the third hole (16.3) on the body (10) are opened. In the fourth position, the third trunnion hole (slotted hole) (21.3) located on the trunnion (20) coincides with the third hole (16.3) on the body (10). In addition, the fourth trunnion hole (21.4) located on the trunnion (20) coincides with the fourth hole (16.4) located on the body (10).

Fifth Position

When the indicator shaft (42) is rotated 180° clockwise, it coincides with the fifth indicator (31.5) on the cap (30). By turning the trunnion (20) with the fifth indicator (31.5), the first gas outlet (11) and the third gas outlet (13) are opened in an adjustable way. With this action, the third hole (16.3) and the fourth hole (16.4) on the body (10) are opened. When the fourth hole (16.4) is active, adjustment can be made via the low flame adjustment (15). In the fifth position, the third trunnion hole (slotted hole) (21.3) located on the trunnion (20) coincides with the third hole (16.3) on the body (10). In addition, the fifth trunnion hole (21.5) located on the trunnion (20) coincides with the fourth hole (16.4) on the body (10).

The third gas outlet (13) located on the gas tap, which is the subject of the invention, reaches to the pilot. Gas can be supplied to a burner via the first gas outlet (11) and to a different burner via the second gas outlet (12). Two different burners can be controlled with a single tap, which is the subject of the invention. In addition, it is possible to control the burners that can burn separately inside and outside, through a single tap.

There is a fixing hole (17) on the body (10). With the said fixing hole (17), the body (10) and the cap (30) are fixed to each other. There is also a fixing hole (32) on the cap (30) that is positioned exactly opposite the fixing holes (17, 32) on the body

7 (10). Connectors such as screws, bolts, nuts, etc. are used in the fixing process. The number of fixing holes (17, 32) mentioned in alternative embodiments of the invention may vary.

By fixing the body (10) and the cap (30), the trunnion (20) and the tail (40), which provides the rotation of the said trunnion (20), are rotated without moving. In this way, a possible gas leakage is prevented through the adjustment holes (16, 21) in the body (10) and the trunnion (20).

In an alternative application of the invention, the fourth burning position can be obtained by adding a new positioning channel, on the condition that the existing adjustment holes (16, 21) on the body (10) remains fixed and a new hole is added or by changing the positions of existing adjustment hole (16, 21) and adding a new adjustment hole (16, 21). In a different alternative application of the invention, a fourth burn is obtained, and this position can be made adjustable by adding a second by-pass to the body (10) for the fourth burn.
