  • the present invention relates to a gas control valve that controls the amount of fuel gas supplied to a gas burner of a gas appliance.
  • a gas appliance such as a gas stove is provided with a flow rate adjusting valve for adjusting the gas supply flow rate and a safety valve for shutting off the gas supply in series.
  • the flow rate adjustment valve includes a rotating body with a closing function that does not allow gas communication in a certain rotation angle range of the motor.
  • the rotating body includes a rotating disk connected to a rotating shaft of a motor and a fixed disk having a plurality of communication holes with different sizes for adjusting the gas flow rate.
  • the rotation angle range of the motor that does not allow gas communication is the range from when the operating rod holding the safety valve starts to move backward. That is, in the gas valve of Patent Document 1, by rotating the motor, first, the operating rod is advanced in accordance with the rotation of the rotating disk to open the safety valve. Thereafter, the operation rod is moved backward by rotating the motor while the safety valve is kept open by the electromagnet. During this time, the position of the communication hole of the rotating disk and the position of the communication hole of the fixed disk are not matched to prevent gas from flowing through the flow rate control valve. When the motor is further rotated, the positions of the communication hole of the rotating disk and the communication hole of any size of the fixed disk coincide with each other, and the gas communication of the flow control valve is allowed.
  • the rotating disk is rotated in conjunction with the rotation of the motor, and both the safety valve and the flow control valve are operated in accordance with the rotation of the rotating disk. That is, the rotating disk is always rotating both when the safety valve is operated and when the flow rate adjusting valve is operated. Further, the rotating disk and the fixed disk are configured such that the disks are brought into close contact with each other by a coil spring so that gas does not leak downstream from the gap between the both disks. For this reason, there is a problem that during the operation of the safety valve and the flow control valve, rubbing always occurs between the rotating disk and the fixed disk, and the reliability of the closing surface is deteriorated due to wear.
  • the present invention has been made to solve such a problem, and an object thereof is to reduce friction generated between a rotating disk and a fixed disk and to suppress wear of a closing surface. .

  • an adhesion force variable portion for making the adhesion force of the rotating disk to the fixed disk variable is further provided so that the adhesion force differs between the safety valve operation range and the flow rate adjustment range.
  • the adhesion of the rotating disk to the fixed disk can be weakened in the flow rate adjustment range compared to the safety valve operation range.
  • the safety valve When operating the safety valve, it is necessary to increase the contact force on the closing surface so that gas does not leak downstream from the gap between the rotating disk and the fixed disk. However, since the rotating disk is stopped at this time, even if the adhesion force is increased, the disk is not rubbed and wear of the closing surface can be prevented.
  • the flow control valve is operated, the gas is supplied, so that the adhesion between the rotating disk and the fixed disk can be somewhat weakened. Since the adhesive force is weak, even when the rotating disk rotates, the friction generated between the rotating disk and the fixed disk can be reduced, and the wear of the closing surface between both disks can be suppressed.
