<p><P>PROBLEM TO BE SOLVED: To provide a safe can protecting valve which smoothly and securely operates. <P>SOLUTION: The can protecting valve is equipped with an inflow passage 1, an outflow passage 2, a packing 4 for blocking the inflow passage 1, a spring 6 for fixing the packing 4 to the inflow passage 1 via a guide 5, a pressure-adjusting shaft 7 for adjusting/setting pressure of the spring 6, and a body 3 which forms an outline. An end part of the guide 5, which is not fixing the packing 4, is formed to be an approximately cylindrical shape, and the approximately cylindrical-shaped end part of the guide 5 is inserted into the spring 6, which firmly fixes the spring and the guide so as to hardly generate leakage between the packing and the inflow passage. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
