Problems solved by technology

[0005] However, in the flow control valve described in the above publication, either the end surface of the air outlet or the end surface of the seal is slightly inclined with respect to the moving direction of the slide shaft, and the posture of the seal may affect the outflow of air.

Embodiment Construction

[0032] Hereinafter, the present invention will be described with reference to the drawings.

[0033] 1 to 3 show a first embodiment of the flow control valve of the present invention. The overall structure of this flow control valve is that both ends of a substantially rectangular valve body 3 are pinched between a cylindrical case 1 and a cover 2, and a solenoid is accommodated in the case 1. 4 and the cylindrical container 6 of the magnet 5. In the through hole 7 of the housing body 6 is fitted a movable valve actuator 8 which pushes the valve body 3 up.

[0034] Specifically, on the side surface of the peripheral wall 11 of the cylindrical case 1 , opposing cut flat surfaces 12 , 12 are provided in parallel. A through hole 14 through which the end of the valve actuator 8 passes is provided at the center of the bottom 13 of the housing 1, and a stepped portion 15 is formed inside the upper opening. The cover body 2 is composed of an upper plate 21 and a peripheral wall 22...

Abstract

A flow control valve capable of increasing a delivery flow rate gradually with a simple structure, comprisinga flowout port to deliver a pressure fluid to the outside, a valve disc having a pressing part to arbitrarily open and close the flowout port, and a valve operating body moving the pressing part of the valve disc, characterized in that, when flow is delivered from the flowout port, the flat surface of the pressing part of the valve disc closing the flowout port is inclined by the delivered flow from the flowout port. The valve disc is formed by proving support plates made of elastic body, 180 deg apart from each other, at the lower end part of the pressing part into which a core is fitted through the bottom part opening of a generally cylindrical packing, the pressing part and support plates are formed of elastic materials such as rubber.

Description

technical field [0001] The present invention relates to a solenoid valve for flow control used as a constant speed exhaust valve such as a sphygmomanometer, and in particular to a flow control valve with a simple structure that can gradually increase the exhaust volume. Background technique [0002] There are various types of sphygmomanometers in the prior art. The usual sphygmomanometer uses a pump to send air to a bandage (カフ) that is wound around the arm of the person to be measured. After the pressure in the bandage is raised to a predetermined value , gradually reduce the pressure, and measure the blood pressure during the decompression. After the blood pressure is measured, the pressure in the band is dropped rapidly, the pressure on the subject's arm is released, and the band is removed from the arm. [0003] For the flow control valve of the sphygmomanometer, it is important to gradually reduce the pressure in the pressurized band, and for this purpose, the size of ...
