Swing Check Valve Having a Apparatus for Preventing Water Hammer and a Apparatus for Preventing Water Hammer

摘要

present invention is water hammer prevention device with swing check valve and water hammer prevention device as the related and more Specifically, the swing check valve is fixed to the rotation shaft of the swing check valve provided on the outside of the plunger is coupled to the electron flow in the longitudinal direction to the rotor that rotates with time and, during the rotation of the rotor By providing the buffer spring applying a force to the plunger, that is coupled to the rotation shaft dongam times of the swing check valve is prevented from rapidly rotating a swing check valve and with a water hammer preventing water hammer prevention device for preventing water hammer relates to an apparatus. To this end, the present invention is, Sikimyeo through the fluid, according to the fluid and prevent the entrance of the circular plate, once the swing check valve comprising a circular plate and bonded to be fixed to the other end of the rotor for rotating the rotor and dongam dongam to rotate once copper, One end of the rotation shaft extends a predetermined interval to the outside of the swing check valve, Once electron to form a hole in the vertical direction to form a plunger chamber that can be coupled to the plunger and the plunger spring and the other end coupled through the turning shaft and the rotating body to rotate together with the rotating dongam; The plunger being coupled to flow along the length of the rotor to the inside of the plunger chamber of the rotor; Plunger spring to provide a spring force is arranged between the plunger and the inner surface of the plunger chamber of said rotor to said plunger; And is arranged separately from the lower portion of the plunger, and a buffer spring for applying an elastic force in the vertical direction of the pivoting radius during rotation of the push stick. ;
