Title:
AIRTIGHT STRUCTURE OF HIGH-PRESSURE FLUID CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2023/058912
Kind Code:
A1
Abstract:
The present invention comprises: a first stepped part formed, in the perpendicular direction with respect to the insertion direction of a component unit, in a component mounting part of a valve body; a second stepped part formed at the outer surface of the component unit so as to face the first stepped part; and an airtight unit disposed between the second stepped part and the second stepped part so as to maintain airtightness between the valve body and the component unit. The airtight unit includes: a lower protrusion part protruding from the upper surface of the first stepped part in a shape in which the tip portion thereof is pointed; an upper protrusion part protruding from the lower surface of the second stepped part in a shape in which the tip portion thereof is pointed; and a sealing member, which is inserted and disposed between the first stepped part and the second stepped part and into which the lower protrusion part and the upper protrusion part penetrate, and thus airtightness is improved.
