Problems solved by technology

[0002] The traditional valve transmission usually uses a rotating shaft, which controls the opening and closing of the valve and the control of the fire of the gas cooker through the rotation of the rotating shaft. The gas valve is usually installed near the gas source of the cooker, so the selection range of the rotating shaft is relatively small. The installation of the gas valve The position is relatively single, which cannot provide a basis for changing the structure of the gas cooker or oven. In order to change the installation position of the knob, make the structure of the gas cooker or oven more diverse, and facilitate the installation of the valve, it is necessary to design a new gas valve. of

Embodiment 1

[0028] When installing, first insert the rotating shaft 13 into the upper cover 9, and at the same time respectively install the positioning pin 14 and the spring II 12 on the insertion end of the rotating shaft 13, and then insert and install one end of the flexible shaft 8 into the insertion end of the rotating shaft 13, At the same time, the lower end surface of the upper cover 9 is sealed with the cover plate 11, the spring II12 is squeezed by the positioning pin 14 and the cover plate 11, and then the valve core 2 is installed in the middle of the body 1, and the spring I5 is vertically installed on the valve core 2 In the middle, insert the positioning sleeve 7 vertically into the valve core 2, and at the same time, the lower end of the positioning sleeve 7 is pressed on the upper end of the spring I5, and then the pin 4 is socketed in the middle of the positioning sleeve 7, and then the other end of the flexible shaft 8 Insert and install in the positioning sleeve 7, and...

Embodiment 2

[0030] When the knob drives the rotating shaft 13 to rotate, the knob must be pressed down first, so that the spring II 12 is compressed, and the positioning pin 14 enters the large-diameter groove from the small-diameter groove of the circular stepped groove 16, and at the same time because the flexible shaft 8 Because of this, the pin 4 and the positioning sleeve 7 are also pressed down synchronously, and then the knob is turned, the rotating shaft 13 rotates, the positioning pin 14 rotates, and after the insertion handle on the positioning pin 14 enters the rectangular groove 15, the knob is released, and the spring The elastic force of II12 makes the knob return, and at the same time, because of the flexible shaft 8, the lower valve is also opened synchronously.

Abstract

The invention relates to a valve structure adopting flexible transmission. A cover plate (11) is mounted on the lower end surface of an upper cover (9); a rotating shaft (13) with the lower end penetrating through the cover plate is vertically mounted in the middle part of the upper cover (9); one end of a flexible shaft (8) is inserted in the lower end of the rotating shaft (13), and the other end of the flexible shaft (8) is inserted in a positioning sleeve (7) positioned in the upper end of a main body (1); a pin (4) is inserted into the middle part of the positioning sleeve (7); the lower end of the positioning sleeve (7) is inserted in a valve core (2) mounted in the middle part of the main body (1); and the end, inserted in the positioning sleeve (7), of the flexible shaft (8) is butted against one end of a spring I (5) vertically mounted in the valve core (2). The valve structure has such characteristics as simple structure and convenience for mounting, and is suitable for various gas stoves or ovens with different structures.

technical field [0001] The invention relates to the field of gas valve manufacturing, in particular to a valve structure adopting flexible transmission. Background technique [0002] The traditional valve transmission usually uses a rotating shaft, which controls the opening and closing of the valve and the control of the fire of the gas cooker through the rotation of the rotating shaft. The gas valve is usually installed near the gas source of the cooker, so the selection range of the rotating shaft is relatively small. The installation of the gas valve The position is relatively single, which cannot provide a basis for changing the structure of the gas cooker or oven. In order to change the installation position of the knob, make the structure of the gas cooker or oven more diverse, and facilitate the installation of the valve, it is necessary to design a new gas valve. of. Contents of the invention [0003] The technical problem to be solved by the present invention is...
