Abstract
The present invention is provide an industrial hydrant comprising an inlet operatively connected to a hydrant body. An inlet valve is in fluid communication with the inlet. A valve guiding is operatively connected to the inlet valve. A main valve within the inlet valve has a main valve outer diameter greater than six inches. The main valve is operatively connected to the valve guiding. A pilot valve within the inlet valve is operatively connected to the main valve and the valve guiding. The pilot valve has a pilot valve outer diameter that is less than the main valve outer diameter.
Claims10
An industrial hydrant, comprising:
- a hydrant body;
- an inlet operatively connected to the hydrant body;
- an inlet valve in fluid communication with the inlet;
- a valve guide operatively connected to the inlet valve;
- a main valve within the inlet valve;
- a pilot valve within the inlet valve;
- wherein the valve guide is disposed at the inlet valve;
- a shaft braced by the valve guide;
- wherein the shaft is coupled to the pilot valve;
- wherein the shaft is coupled to the main valve;
- wherein the main valve has a seal;
- wherein the seal defines an opening;
- wherein the pilot valve has a closed position and an opened position;
- wherein the pilot valve is seated inside the opening of the seal to seal against the seal to prevent fluid flow when in the closed position;
- wherein the pilot valve is unseated from the opening in the seal to allow the fluid flow through the opening in the seal when in the opened position;
- wherein the inlet valve has a valve body;
- wherein the seal has an outer periphery;
- wherein the outer periphery of the seal seals against the valve body when the main valve is closed;
- and
- wherein the outer periphery of the seal is unseated from the valve body to allow the fluid flow between the seal and the valve body when the main valve is opened.
An industrial hydrant, comprising:
- a hydrant body;
- an inlet operatively connected to the hydrant body;
- an inlet valve in fluid communication with the inlet;
- a valve guide operatively connected to the inlet valve;
- a main valve within the inlet valve;;
- the main valve operatively connected to the valve guide;
- a drain within the inlet valve;;
- the drain is operatively connected to the valve guide;
- a valve body defining at least two drain openings;
- wherein the drain includes at least two drain valves;
- wherein each drain valve is associated with a corresponding one of the drain openings;
- and
- wherein each drain valve includes:
- a drain valve body;
- a spool slidably disposed in the drain valve body;
- a valve spring disposed between the spool and the drain valve body;
- wherein the spool has an opened position where the spool opens the corresponding drain opening;
- wherein the spool has a closed position where the spool closes the corresponding drain opening;
- and
- wherein the valve spring biases the spool to the closed position.
