Check Valve For Use With High Pressure Pump
US Patent:
4393895, Jul 19, 1983
Filed:
May 14, 1981
Appl. No.:
6/263506
Inventors:
Robert J. Rubey - Wisconsin Rapids WI
Assignee:
Sterling Drug Inc. - New York NY
International Classification:
F16K 1504
US Classification:
1375395
Abstract:
A check valve for use with a high pressure sludge pump in which a valve member such as a ball is movable toward and away from a valve seat in the inlet to the valve housing, and which valve has a valve member lift limiter adjustably mounted on the valve body and extending into the path of movement of the valve member for engaging it and limiting movement of the valve member away from the valve seat, a plunger mounted for movement toward and away from the valve seat in the position closest to the valve seat, projecting past the valve member lift limiter toward the valve seat and having the end toward the valve member spaced from the valve member and permitting movement of the plunger away from the valve seat sufficiently far to permit the valve member to engage the valve lift limiter.
Ball Type Check Valve
US Patent:
4243067, Jan 6, 1981
Filed:
Nov 15, 1979
Appl. No.:
6/094732
Inventors:
Robert J. Rubey - Wisconsin Rapids WI
Assignee:
Sterling Drug Inc. - New York NY
International Classification:
F16K 1504
US Classification:
13732903
Abstract:
A check valve which has top and bottom flanges and a valve body thereinbetween. The flanges have aligned holes therethrough which serve as an inlet (bottom flange) and an outlet (top flange) for fluid flowing through the valve. A spherical ball is contained within the valve body and rests on a ball seat surrounding the inlet. A top plate is positioned adjacent to the top flange and has an opening therethrough which diverges concentrically toward the outlet opening, and a ring shaped ball stop which receives the ball when it is forced away from the ball seat by the fluid is positioned between the top plate and the top of the ball. Also, the inlet may have a restricted portion so that a diverging portion of the inlet opens into the valve body.
