<p><P>PROBLEM TO BE SOLVED: To provide a relief valve usable for all purposes regardless of a diameter of a relief pipe and a screw shape, and easy in adjusting relief pressure. <P>SOLUTION: This relief valve has a valve element, a spring means for closing a flow passage by seating this valve element on a valve seat, and a connecting part to the relief pipe, and separates the valve element from the valve seat when internal pressure of the relief pipe exceeds valve closing pressure by the spring means. The relief valve is constituted by using the valve seat, a cylindrical valve body having the valve element and the spring means and a retainer body connected to the relief pipe as a separate member, and joins the cylindrical valve body and the retainer body. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
