Abstract
A regulator valve includes a valve body defining a central bore with a longitudinal axis. A rod couples to a diaphragm and slides along the longitudinal axis within the central bore. The rod has a planar end. A spring, such as a helical spring, mounts in the central bore and engaging the rod. One or more parallel passages are formed in the valve body extend parallel to the bore. One or more slots are formed in the valve body, each of the one or more slots connecting one of the one or more parallel passages to the central bore. The regulator valve may be used in a pumping system as a pressure regulator.
Claims17
A regulator valve comprising:
- a valve body defining a central bore with a longitudinal axis;
- a diaphragm;
- a rod coupled to the diaphragm and sliding along the longitudinal axis within the central bore, the rod having a planar end transverse to the longitudinal axis;
- a spring mounted in the central bore and directly engaging the rod;
- one or more parallel passages formed in the valve body extending parallel to the bore;
- and
- one or more slots, each of the one or more slots connecting one of the one or more parallel passages to the central bore;
- wherein each of the one or more slots has a cross-sectional area smaller than a cross-sectional area of each of the one or more connected parallel passages to form a connecting neck between the central bore and one of the connected parallel passages.
A regulator valve comprising:
- a valve body defining a central bore with a longitudinal axis;
- a diaphragm;
- a rod coupled to the diaphragm and sliding along the longitudinal axis within the central bore, the rod having a planar end;
- a spring mounted in the central bore and engaging the rod;
- a plurality of parallel passages formed in the valve body extending parallel to the bore;
- and
- a plurality of slots, each of the plurality of slots connecting one of the plurality of parallel passages to the central bore:
- wherein each of the plurality of slots has a cross-sectional area smaller than a cross-sectional area of each of the connected parallel passages to form a connecting neck between the central bore and one of the connected parallel passages.
A diaphragm pump system comprising:
- a diaphragm pump having a transfer chamber containing hydraulic fluid;
- a first valve allowing hydraulic fluid into the transfer chamber;
- a second valve allowing hydraulic fluid to be removed from the transfer chamber;
- a hydraulic fluid reservoir in fluid communication with the transfer chamber;
- wherein a hydraulic fluid pressure is above a pumped fluid inlet feed pressure;
- a pressure bypass regulator valve bypassing fluid flow to the transfer chamber, the regulator valve comprising:
- a valve body defining a central bore with a longitudinal axis;
- a diaphragm;
- a rod coupled to the diaphragm and sliding along the longitudinal axis within the central bore, the rod having a planar end;
- a spring mounted in the central bore and engaging the rod;
- a plurality of parallel passages formed in the valve body extending parallel to the bore;
- and
- a plurality of slots, each of the plurality of slots connecting one of the plurality of parallel passages to the central bore;
- wherein each of the plurality of slots has a cross-sectional area smaller than a cross-sectional area of each of the connected parallel passages to form a connecting neck between the central bore and one of the connected parallel passages.
