Title: Safety valve
Inventor: SHINKAWA TOSHIKAZU
IPC: F16K17/04
Filed: 1985-08-02
Abstract: PURPOSE:To prevent the function as safety valve by pressing a valve piece onto a valve seat by a fluid pressure and separating the valve piece from the valve seat when the fluid pressure reaches a set pressure. CONSTITUTION:The surface pressure of a contact surface increases through the adding of the pushing-up load of the fluid pressure acting onto the pressure receiving surface of a valve piece 7, onto the pushing load of a spring 6 together with the increase of the fluid pressure, and a self tightening type safety valve is formed. Since the contact surface pressure increases as the fluid pressure increase, the leak of high-pressure fluid is prevented. When the pressure of the high-pressure fluid which flows in a pipe 15 increases to a set pressure, the load for pressing down a piston 10 increases, and a piston rod 11 contacts with a valve rod 4, and the valve piece 7 is departed from a valve seat 2d.
