The present invention provides a vibration reducing device for pump cover body of water shut-off diaphragm pump comprising a hood cover mount and a pump cover body with a containing pit, which orderly accommodates a plastic elastic membrane disk, an obstructing baffle and a compressed spring therein. The plastic elastic membrane disk includes a downward central flow directing buffer, which can insert into a flow directing compartment in the containing pit when the hood cover mount docks with the pump cover body. The flow directing buffer can not only absorb the direct impacting momentum of pumped high pressurized water to the surrounding internal wall of the flow directing compartment but also redirect the random impacting direction of the high pressurized water. Thus, the vibration of the pump cover body with annoying noise created by the impacting momentum of the high pressurized water is deleted.

1. A vibration reducing device for pump cover body of water shut-off diaphragm pump comprises a pump cover body, a hood cover mount, a plastic elastic membrane disk, an obstructing baffle and a compressed spring, wherein: said pump cover body, which is a hollow body with a downward opening and an internal tiered rim encompassing a nested annular well wall, includes a containing pit outwardly configured on the top thereof, an inlet port, an outlet port respectively disposed in the peripheral thereof as well as an intensively high-pressured water chamber is created between the internal wall of the annular well wall and top surface of an upper valvular cover; wherein, a central vertical top opening flow directing compartment with a horizontal outlet passage connecting with the outlet port, a plurality of vertical perforated bores and a water passage with a leading space are created at the lower section of said containing pit so that the high-pressured water chamber and containing pit are communicable while the inlet port, the leading space and containing pit are communicable because the perforated bores surrounds the flow directing compartment with a separating cylinder interposed between them while the water passage externally leads the perforated bores with a separating cylinder interposed between them;said hood cover mount, which is inset in the containing pit of the pump cover body, has a closed top and a downward annular well wall with a plurality of radial flow directing bores disposed on the lower section;said plastic elastic membrane disk, which attaches on the upper opening of the flow directing compartment in the pump cover body, includes a top surface, a sole surface, an outer peripheral, a downward central flow directing buffer and a marginal raised rim abutting the joint of the top surface and outer peripheral;said obstructing baffle, which is a planiform plastic disk to be attached on the top surface of the elastic membrane disk, includes a top surface, a sole surface and an outer peripheral jointing the top surface and sole surface as an integral, wherein the outer diameter of the obstructing baffle is slightly smaller than inner diameter of the annular well wall so that the obstructing baffle is inset into the annular well wall of the hood cover mount; andsaid compressed spring has one end thereof attached against the top surface of the obstructing baffle and the other end thereof attached against the bottom rim for the annular well wall of the hood cover mount. 2. The vibration reducing device for pump cover body of water shut-off diaphragm pump as claimed in claim 1, wherein the shape of the flow directing buffer on the elastic membrane disk is a cylinder, cone or inverted cone. 3. The vibration reducing device for pump cover body of water shut-off diaphragm pump as claimed in claim 1, wherein said elastic membrane disk is further modified to dispose a central orienting shaft on the top surface thereof while said obstructing baffle is also adapted to create an additional corresponding central oriented base with an oriented hole therein. 4. The vibration reducing device for pump cover body of water shut-off diaphragm pump as claimed in claim 1, wherein said elastic membrane disk is further modified to dispose a concentric bulged ring inside of the raised rim on the top surface thereof while the obstructing baffle is also adapted to create a corresponding concentric dented ring inside of the outer peripheral thereof. 5. The vibration reducing device for pump cover body of water shut-off diaphragm pump as claimed in claim 1, wherein said hood cover mount is further adapted to dispose a pair of opposed displacement limiters inside the annular well wall thereof. 6. The vibration reducing device for pump cover body of water shut-off diaphragm pump as claimed in claim 1, wherein said pump cover body is further modified to dispose a plurality of concentric anti-leakage rims at the internal bottom of the containing pit therein.
