という効果がある。 In the above configuration, when a current is passed through the coil 6, an electromagnetic force is generated, which acts to push the plunger 7 downward. This electromagnetic force changes depending on the magnitude of the current. This electromagnetic force acts to push the valve body via the push rod 9 and rod 13. Then, according to the well-known governor principle, the pressure of the fluid flowing out from outlet 2 is P 2
is determined by the force acting on the valve body. That is, the pressure P 2 can be arbitrarily changed within a certain range by changing the current value passed through the coil 7. In such an electromagnetic pressure proportional controller that attempts to arbitrarily set the secondary pressure P 2 over a wide range, the difference between the primary pressure P 1 at the inlet 1 and the secondary pressure P 2 at the outlet 2 may be large, and the valve Naturally, there are many cases where the opening gap between the seat 3 and the valve body 4 becomes small, and the flow velocity of the fluid passing through that gap is high, so the vibration of the valve body 4 is set to the maximum rating like a normal pressure regulator. It is much more likely to occur compared to other things. However, in this embodiment, the fixed partition wall 21 is adjacent to the diaphragm 5.
and a damper bracket 1 having a damper hole 15.
4, a damper chamber A is provided, and since the diaphragm 5 and the fixed partition wall 21 are adjacent to each other, this damper chamber A on the atmospheric pressure side forms a thin and flat space in which the valve body 4 and the diaphragm 5 move. The rate of change in damper chamber volume is extremely large. Therefore, the movement of the valve body 4, that is, the movement of the diaphragm 5, is as follows.
The air in the damper chamber A passes through the damper hole 15, and an extremely large amount of air enters and exits through the damper hole, causing the diaphragm 5 and the valve body 4 to pass through.
suppress the rapid movement of That is, the rapid movement of the valve body 4 and the diaphragm 5 generates a positive or negative pressure relative to the atmospheric pressure in the damper chamber 1, and this pressure constantly acts on the diaphragm 5 in the opposite direction to its movement direction, causing minute This also has the effect of preventing valve vibration.

保つという効果がある。 Further, a rod hole 22 is provided in the fixed partition wall 21, a rod 13 is inserted into the rod hole, and the lower end is inserted into the valve body 4.
Due to the configuration in which the plunger 7 is in contact with the cantilever leaf spring 10, even if the plunger 7, which is supported by the two cantilever leaf springs 10, moves up and down while oscillating in an arc, the rod 13 moves only in the up and down direction and the valve is closed. It acts to transmit force to the valve body 4, and has the effect of maintaining stable pressure characteristics without causing the valve body 4 to oscillate laterally.

く安定した圧力特性を得る効果がある。(1) A damper bracket with a fixed partition wall is provided adjacent to the diaphragm to form a thin damper chamber within the movable range of the diaphragm, and the fixed partition wall has a damper hole and a rod hole, and the rod is inserted into the rod hole. Since the structure is such that the spring is inserted into the valve body and comes into contact with the valve body, the volume ratio is significantly lower than that of conventional pressure controllers (e.g., JP-A-138429), which include a spring storage volume for pressure setting in the atmospheric chamber. The large damper effect acts as an extremely high vibration prevention effect over a wide range,
Even if the secondary pressure P2 is throttled down to a small range by an electric signal, no valve vibration occurs. In addition, even if the operation of a force applying part such as an electromagnetic plunger that changes force arbitrarily by an electric signal has a lateral oscillation element, the rod acts to transmit force only in the axial direction to the valve body through the rod hole. This has the effect of obtaining stable pressure characteristics without causing sideways movement of the valve body.

弁振動もなく動作の安定した電磁圧力比例制御
器を実現できるため、ガス燃焼器に応用すれば

できる。(2) A wide pressure range can be arbitrarily varied electrically;
Since it is possible to create an electromagnetic pressure proportional controller that operates stably without valve vibration, if applied to a gas combustor, the amount of combustion can be controlled safely and reliably using electrical signals, and gas appliances that are extremely easy to use can be realized.
