Description of the invention (1) < Technical Field to which the Invention belongs > The present invention relates to a rotary gas valve device, which has a free (please read the precautions on the back before filling this page) free bismuth The gas cock and safety valve of the closed parts are mainly suitable for gas furnaces. < Known technology > In this type of gas valve device, generally, a safety valve is arranged on the extension line of the axis of the gas cock, so that the safety valve is opened and closed in the direction of the axis of the gas cock. The valve device forms a long object in the axis direction of the gas cock, and when the operation button is arranged on the gas furnace, the axis direction of the gas cock becomes the vertical direction. If the gas furnace is thin, it should be stored within the height of the gas furnace. The gas valve device becomes difficult. Here, it is known that a gas valve device which is arranged so that the safety valve switch is perpendicular to the axis direction of the gas cock and shortens the length of the axis direction of the gas cock according to Japanese Patent Application Laid-Open No. U_63252 is also widely known. In the gas valve device in which the gas cock and the safety valve are vertically arranged in this way, when the operating shaft for the gas cock is rotated to the ignition position from the flameout position, a linkage mechanism for pressing the valve opening safety valve becomes necessary. In the conventional example, the driving member for the linkage mechanism is mounted on the operation shaft, which is different from the rotation force transmission member toward the closing member mounted on the operation shaft. The driven member drives the driven member of the linkage mechanism to constitute a safety valve to be pressed to open the valve. < Problems to be Solved by the Invention > In the conventional device described above, the length in the direction of the plug axis of the gas valve device is increased only in the arrangement space of the driving member. ) A4 specification (21〇 < 297 public love) 544499 A7 B7 V. Description of the invention (Increase the cost and increase the inconvenience. In view of the above points, the present invention provides a way to shorten the plug shaft and line # direction as much as possible. The problem of the rotary gas valve device which can reduce the cost and reduce the cost. <Means for Solving the Problem> ^ In order to solve the above problem, the rotary gas valve device of the present invention includes a one-gas plug, A freely rotatable closing member; a safety valve configured to switch in a direction perpendicular to the axis direction of the gas cock; an operating shaft for rotating the closing member to switch the gas cock; and 'a linkage mechanism for use In order to make the operating shaft rotate from the closed position to the open position to press the safety valve to open the valve; and the linkage mechanism includes a driving part, which is provided by Chaoan A rotating force transmitting member is integrally extended from a closing member that transmits a rotating force to the operating shaft; and a driven member is driven to rotate the operating shaft from the flameout position to the ignition position through the driving portion to be pressed to open According to the present invention, the rotational force transmitting member toward the closing member forms a driving member for the linkage mechanism. Therefore, the axial direction of the operation shaft, that is, the axial direction of the gas cock is not ensured. The dedicated arrangement space for the driving member can be completed. For this reason, the length in the axial direction of the plug valve of the gas valve device can be shortened, and the number of parts can be reduced to reduce costs. Moreover, a slide plate can be used as a driven member, but a slide plate may be possible. Occurrence of sheath tail leads to inaccurate movement. In order to improve the stability and certainty of movement, it is most desirable to use a free-swinging shaft to support the operation around a specific axis.

Description of the invention (3) " 'Vertical # is described as a "moving member" in the aforementioned Japanese Patent Application Publication No. ^ ⑹ Plus publication also uses # 纵Pole. In this case, use a control lever that is perpendicular to the opening and closing direction of the safety valve to make the control lever rock freely in the direction of the safety purpose switch, and drive through the drive unit to the ignition position _, and stop the drive. The vertical rod is shaken to the position where the safety valve can be pressed to open the valve, but if the axis of the joystick is parallel to the axis of the gas cock, after the ignition of the operating shaft is ignited to the burner, in order to release the pressure of the safety valve to open the valve, It is necessary to return the operating shaft from the ignition position to a few rotations to return the joystick to the inactive position. For this reason, in the device described in the aforementioned Japanese Patent Application Laid-Open No. ^^^, when the pressing of the operating shaft in the axial direction is released between the operating shaft and the closing member, the operating shaft is retracted and rotated to form a cam mechanism, so that Rotating from the pressure of the beacon position, after rotating the operating shaft to the ignition position, the pressing of the operating shaft is released, the operating shaft is retracted and rotated, and the joystick is restored to the inactive position. However, in this device, The cam mechanism shortens the length in the axial direction of the gas cock, and creates an obstacle in reducing costs. For this, if the freely swinging shaft support lever is perpendicular to the direction not only the opening direction of the safety valve but also the axis direction of the gas cock, If the axis is around the axis, the joystick can be moved not only by the rotation of the operating shaft but also by the movement in the axial direction of the operating shaft. Moreover, a cam portion that raises the driving portion by rotating toward the ignition position of the operating shaft is provided on the joystick, and The cam portion is formed to "if the operating shaft is pushed into the axial direction, the joystick is shaken to the position where the safety valve can be pressed to open the valve, and if it is released If the shaft is pushed in, the joystick will be shaken to the inactive position where the pressure of the safety valve can be released.

(A), the pressing force of the driving portion 24a acts on the cam portion 6d, the joystick 6 is rocked to the operating position, and the pressing of the operation shaft 23 is released. As shown in FIG. 5 (B), the driving portion is used. 24a releases the depression of the cam portion 6d, and the lever 6 is restored to the inactive I position by the force of the spring 38 of the push rod 37. Then, the operation shaft 23 is rotated to the position of the stop by the pressure of the stop position. After the ignition position, the joystick 6 is shaken to the actuated position, the safety valve 3 is pressed to open the valve, and the gas is supplied to the burner B through the safety valve 3 and the gas cock 2; at the same time | the ignition switch 4 is turned on to ignite the burner and, in After the ignition is released after ignition, the lever 6 is shaken to return to the inactive position, the pressure opening of the safety valve 3 is released, and the ignition switch 4 is turned off at the same time. Even if the pressure opening of the safety valve 3 is released, The safety valve 3 absorbs the electric power from the thermoelectric pair used for flame detection and keeps it in the valve open state. However, before the thermoelectric pair outputs sufficient electric power, if the pressure of the operating shaft 23 is released, the valve burner of the safety valve 3 will fire. .In this case, press into the operation again After the shaft 23, the joystick 6 is shaken to the actuated position and then ignited to the burner B. Therefore, it is not necessary to return the operation shaft 23 to the stop position during re-ignition, and the re-ignition operation becomes easy. In this embodiment State, by driving the lever 6 as a driven member for the interlocking mechanism toward the latch 24 as the rotation force transmitting member of the closing member 21 mounted on the operating shaft 23, further, even if the operating shaft 23 is not retracted from the ignition position This paper size applies to China National Standard (CNS) A4 specification (210X297 mm) -10--·-........ ......... 11 ^ · (Please read the precautions on the back before filling in this page) 544499 A7 B7 V. Description of the invention (8) Rotate back and return the joystick 6 to the inactive position Release the pressure of the safety valve 3 to open the valve. For this reason, it is not necessary to provide a cam mechanism, so that the driving member and the operating shaft of the linkage mechanism are rotated back, and the number of parts can be reduced to reduce costs. At the same time, the length of the gas valve device D in the axial direction of the plug can be reduced. The valve device D is housed in a thin gas furnace. In addition, the rotational force transmitting member is not limited to the latch 24, and for example, a sheet metal member having an engagement hole formed at the upper end of the closing member may be used. In addition, in the above-mentioned embodiment, after the ignition is turned to the burner B by the rotation toward the ignition position of the operation shaft 23, the operation shaft 23 is reversed from the ignition position to the stop position to adjust the firepower, but at the operation shaft 23 After the press-in of the ignition position is released, the operating shaft 23 can be further rotated forward from the ignition position, and the gas valve device for adjusting the firepower by the forward rotation can also be applied to the present invention. <Brief Description of Drawings> Fig. 1 is a perspective view of a gas furnace provided with a gas valve device according to the present invention.
