Kind Code:
A1
Abstract:
The present invention relates to a sealing member for a fluid control valve and, more specifically, to a sealing member for a fluid control valve wherein sealing power can be obtained by using the fluid pressure generated when the valve is closed and excellent heat resistance and wear resistance can be achieved. In other words, a sealing member for a fluid control valve of the present invention comprises: a valve body; first and second flow passages formed in a valve chamber of the valve body; a valve seat formed at a portion where the first and second flow passages communicate with each other; and a valve member which is spaced apart from or in contact with the valve seat to control fluid, wherein a rear end of the valve member is elastically supported by a spring and is fitted and coupled to the valve seat and a support guide having a support end portion formed to be supported when the valve member moves backward, and to the valve seat, and the sealing member includes a pressing groove portion formed on a front surface portion to generate pressurizing force by introducing fluid and pressurizing wings formed on both sides of the pressing groove to be pressed outward by the pressurizing force of the fluid.
