Title: Over-flow preventing valve
Inventor: FUJII YOSHIO
IPC: F16K17/34
Filed: 1981-07-31
Abstract: PURPOSE:To prolong the period of movement of a ball valve in a cylindrical chamber, by disposing a ball valve on the inside of a helical projection arranged in the cylindrical chamber, and selecting the inner diameter of said helical projection to be slightly larger than the diameter of the ball valve, so that the speed of movement of the ball valve is reduced at a plurality of positions in the cylindrical chamber. CONSTITUTION:When a quick opening valve is opened, pseudo over-flow is started instantaneously and a ball valve 3 begins to rise from an initial displaced position. At the first stage of upward movement of the ball valve 3, the direction of its movement is changed along the inclination of the first turn of a coil spring 6 located at the bottom thereof. Then, the ball valve 3 comes into abutment with the next turn of the coil spring 6 and the direction of its movement is changed again. Thus, the speed of movement of the ball valve 3 is reduced each time it collides against the turns of the coil spring 6, so that the pseudo overflow is eliminated before the ball valve 3 reaches a valve seat 4 and fluid flow in a cylindrical chamber 1 restores its steady flow.

Abstract: PURPOSE: To inhibit a hysteresis phenomenon, by mounting an auxiliary passage, which communicates the suction side and the discharge side when a diffuser displaces in response to pressure difference between the suction side and the discharge side, and a coil spring to an outer circumference portion of the diffuser.  
     CONSTITUTION: When pumping-up quantity becomes much, cavitation is generated, the pressure of a suction chamber 11 becomes lower than the pressure of a suction port 21, and a diffuser 4 moves to the centrifugal pump 1 side by pressure difference to communicate an auxiliary passage 25, thus obtaining a fixed pumpling-up quantity added with water passing through the diffuser 4. When slowly lowering pumping-up quantity, there is an indication that delay is generated to adherence operation between a collar portion 41 and a seat surface 27 by cavitation, but pressure  differnce between the suction chamber 11 and the suction port 21 may be small  values corresponding to the elastic portion of a coil spring 6 because the diffuser 4  is pressed by means of the coil spring 6, thus resulting in adherence in pumping-up  quantity Q 1  slightly less than pumping-up quantity Q 2 . Consequently, a hysteresis  phenomenon can be inhibited extremely little
