Abstract

PURPOSE: To prevent pressure from surging, chattering, etc. by a method wherein the valve body of a relief valve is pushed by a spring to a movable valve seat body pressed by the movable iron core of a fluid pressure proportional electromagnet and a difference is generated by a rapid rise of the fluid pressure to a displacement between the valve body and the valve seat body.
CONSTITUTION: A proportional electromagnet 2 is electrified to have a preset value. When fluid pressure rises slowly, a valve body 31a and a movable valve seat body 10 displace up to the preset value in a unitary body respectively by the fluid pressure and the pressure of the proportional electromagnet 2. However, when a rapid rise of pressure occurs, the valve body 31a displaces rapidly by the pressure of the fluid. On the other hand, the pressure of a movable iron core 75 by a push pin 76 of the proportional electromagnet 2 is so small that the displacement of the movable valve seat body 10 to the left direction occurs later than that of the valve body 31a. The valve body 31a and the valve seat body 10 separate before they reach the preset pressure to release the fluid pressure. Since the valve is released before the preset pressure is reached, delay of motion based on rapid change of pressure and occurrence of surface pressure are prevented.
