った。2. Description of the Related Art Conventionally, as a valve for automatic opening / closing control of gas appliances such as city gas and the like, a small solenoid valve operated by using a dry battery or the like has been used. Calculating the force required to open and close a valve with a diameter of 28 mm used at the end of a user of pipes such as city gas, for example, a solenoid valve that opens and closes a fluid with a gas pressure of 500 mm with a valve with a diameter of 28 mm closes the valve. On the back of the valve in condition, about 30
0g back pressure acts. The electromagnet that opens and closes such a valve must use a large electromagnet with an initial pulling force of 550 g and a stroke of about 6 mm, applying the spring force of the valve presser.

ション構造としたものなどが知られている。On the other hand, a small pilot valve for equalizing pressure is added to the valve to open the pilot valve prior to opening the valve to eliminate the pressure difference between the upstream and downstream of the valve and reduce the force required to open and close the valve. There is a technology for reducing the differential force of the motor. Such a pilot valve is provided with a bypass passage in the valve and disposed in the bypass passage. The pilot valve is machined in the valve body itself, and the valve stem of the valve body is a two-stage motion structure in which the pilot valve is opened and the valve body is opened. And so on are known.

うな可撓性を有するものとする。In the present invention, a valve element having flexibility in the valve opening / closing direction is used. This valve body uses a circular plate, for example, a valve body made of a rubber plate. When the valve stem is moved up and down by a small distance when there is a pressure difference between the upstream and downstream sides of the valve stem, the outer edge of the valve stem and the valve stem mounting part allow a slight deformation in the valve stem operating direction. It is assumed to have such flexibility.

易に弁を開くことができる。In the valve of the present invention configured as described above, when the valve stem is pulled up to open the valve, the valve body is deformed first, and then the push-up member presses a point near the valve seat of the valve body. Partially open body and valve seat seals. Opening this partial seal equalizes the pressure upstream and downstream of the valve,
The back pressure due to the pressure difference disappears and the valve stem can then easily open the valve with a small force.
