Abstract

12,911. Davis, A. E. June 7. Pump valves.- In order to prevent excessive wear in the valves and seatings, particularly those used for pumping gritty liquids, each valve has a primary seating b<1>, which may be flat, conical, or spherical, and a secondary seating b'. Between this seating and the valve is a ring c of india-rubber or other resilient material, which when closed encloses any dirt, thus preventing it from choking the valve, and, when released, allows it to be washed away by the current of water. This packing ring is kept in place by a metal ring e, which is placed outside the ring when the valve is closed by the pressure of water.
