Shock damper for outlet pipe of diaphragm pump

Abstract

The present invention provides a shock damper for outlet pipe of diaphragm pump comprising a shock damper pod including an intake jointer, an outtake jointer, a stroke cavity and a cap receptacle, a damping block, a damping elastomer and a damper cap. After screwing the intake jointer into the water outlet orifice of the pump upper hood with motor power on, pressurized water come from high-pressured chamber will flow into water intake channel of shock damper pod to impact damping block in periodically pulsatile manner; Meanwhile, resilient force of compressed spring will offset the periodic impact of pressurized water in counteracting damper manner so that pressurized water will become a steady flow without any pulsation. Accordingly, the shock damper not only can obviate the shock and vibration for the outlet pipe but also can reduce the shock and annoying noise in the pump upper hood.

1 . A shock damper for outlet pipe of diaphragm pump comprising:
 a shock damper pod;   a damping block;   a damping elastomer; and   a damper cap,   wherein said shock damper pod is an unitarily molded integral hollow cylinder, includes an intake jointer, an outtake jointer, a stroke cavity and a cap receptacle, wherein said intake jointer, which is male threaded for engaging with a water outlet orifice of the pump upper hood, has a water intake channel run throughout with a distal end connecting with the proximal top end of the stroke cavity in inter-fluent communicable manner; said outtake jointer, which is disposed at the lateral wall of the shock damper pod with male and female threaded manner, has a water outtake channel run throughout with a upper end connecting with the lateral wall of the stroke cavity in inter-fluent communicable manner; said stroke cavity is a hollow cavity; and said cap receptacle is female threaded,   wherein said damping block is an adapted cylinder inserted in the stroke cavity of the shock damper pod, which includes a closed top surface and a bottom sole with a dented receptacle,   wherein said damper cap is engaged in the stroke cavity of the shock damper pod, which includes a central holding dent with an outer male thread, and   wherein said damping elastomer has outer diameter thereof is less than the inner diameter of the dented receptacle in the damping block and the inner diameter of the holding dent in the damper cap.   
   
   
       2 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 1 , wherein a gasket is further disposed to sleeve over the damping block near the top surface of said damping block. 
   
   
       3 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 1 , wherein a washer is further disposed to sleeve over the male thread peripheral of said damper cap. 
   
   
       4 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 1 , wherein said damping elastomer is a compressed spring. 
   
   
       5 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 1 , wherein a truncated conical directing spoiler is further centrally configured on the top surface of said damping block. 
   
   
       6 . A shock damper for outlet pipe of diaphragm pump comprising:
 a shock damper pod;   a damping block;   a damping elastomer; and   a damper cap,   wherein said shock damper pod is an extended hollow cylinder integrated with the water outlet channel of the pump upper hood on the diaphragm pump, and comprises an outtake jointer, a stroke cavity and an open cap receptacle end, wherein said stroke cavity is inwardly created from the open cap receptacle end to communicate with the water outlet channel in the diaphragm pump of automatic water cutoff type having inner diameter being bigger than that of the water outlet channel; said outtake jointer, which is disposed at the lateral wall of the shock damper pod with male and female threaded manner, has a water outtake channel run throughout with a upper end connecting with the lateral wall of the stroke cavity in inter-fluent communicable manner; and said cap receptacle end is female threaded,   wherein said damping block, which is an adapted cylinder inserted in the stroke cavity of the shock damper pod, includes a closed top surface and a bottom sole with a dented receptacle,   wherein said damper cap, which is engaged in the stroke cavity of the shock damper pod, includes a central holding dent with an outer male thread, and   wherein said damping elastomer has outer diameter thereof is less than the inner diameter of the dented receptacle in the damping block and the inner diameter of the holding dent in the damper cap.   
   
   
       7 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 6 , wherein a gasket is further disposed to sleeve over the damping block near the top surface of said damping block. 
   
   
       8 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 6 , wherein a washer is further disposed to sleeve over the male thread peripheral of said damper cap. 
   
   
       9 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 6 , wherein said damping elastomer is a compressed spring. 
   
   
       10 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 6 , wherein a truncated conical directing spoiler is further centrally configured on the top surface of said damping block. 
   
   
       11 . A shock damper for outlet pipe of diaphragm pump as claimed in  claim 6 , wherein said shock damper pod, which is an extended hollow cylinder integrated with the water outlet channel of the pump upper hood on the diaphragm pump of automatic water cutoff type, comprises an outtake jointer, a stroke cavity and an open cap receptacle end, wherein said stroke cavity is inwardly created from the open cap receptacle end to communicate with the water outlet channel in the diaphragm pump of automatic water cutoff type having inner diameter being bigger than that of the water outlet channel; said outtake jointer, which is disposed at the lateral wall of the shock damper pod with male threaded manner, has a water outtake channel run throughout with a upper end connecting with the lateral wall of the stroke cavity in inter-fluent communicable manner; and said cap receptacle end is female threaded.
