の長さおよび位置を設定してなる比例制御弁。[Scope of Claim for Utility Model Registration] A needle-shaped valve that energizes the stator (■) of a motor to rotate the rotor (■), converts the rotation into linear motion of the valve stem (■) by means of a screw, and interlocks with the valve stem (■). In a proportional control valve that controls the flow rate by changing the gap between ■ and the valve seat ■ in the valve body ■, the needle valve ■ and the valve stem ■ are connected via a compression spring A and a weight, and the valve stem ■ A compression spring BO is attached to the other end, and when the valve is closed, the needle valve ■ is seated on the valve seat ■, and then the compression spring A [Co., Ltd.] is compressed, and when the valve is opened, the compression spring BO is attached to the bottom of the case row. The valve is configured so that it is compressed after it comes into contact with the valve, and when each compression spring is activated, the female screw of the rotor ■ and the male screw of the valve stem ■ will come off when the amount of spring compression reaches a predetermined amount. The position of the male thread on the valve stem and the female thread on the rotor [phase]
A proportional control valve whose length and position are set.
