Abstract

A pressure relief ball valve to prevent excessive pressure buildup due to freezing liquid includes a ball that is rotatably housed within a valve body. A fluid conduit traverses through the ball, wherein rotation of the ball via a lever handle either aligns or disjoints the fluid conduit with an inlet and an outlet of the valve body. Meanwhile, a drain hole traverses into the ball and intersects the fluid conduit. When the ball is toggled to an open position, the drain hole is positioned adjacent to a side wall of the valve body, such that the drain hole is capped off. When the ball is toggled to a closed position, the drain hole is positioned adjacent to the outlet, wherein residual liquid is expelled from the fluid conduit. The removal of residual liquid prevents excessive pressure buildup due to freezing liquid within the valve body.

Claims

1. A pressure relief ball valve comprises:

a valve body comprising an inlet, an outlet, and a valve chamber;

the valve chamber being positioned in between the inlet and the outlet;

a ball being rotatably mounted within the valve chamber;

a fluid conduit traversing through the ball;

a drain hole traversing into the ball;

the drain hole being angularly offset from the fluid conduit;

the drain hole being in fluid communication with the fluid conduit;

a lever handle being operably coupled to the ball;

the ball being configurable between an open position and a closed position through the lever handle;

the drain hole being offset from the outlet when the ball is in the open position;

the fluid conduit being in fluid communication with the inlet and the outlet when the ball is in the open position;

the drain hole being positioned adjacent to the outlet when the ball is in the closed position; and

the fluid conduit being disjointed from the inlet and the outlet when the ball is in the closed position.

2. The pressure relief ball valve as claimed in claim 1 comprises:

the drain hole being perpendicular to the fluid conduit.

3. The pressure relief ball valve as claimed in claim 1 comprises:

a stem traversing through the valve body;

the stem being engaged with the ball; and

the lever handle being terminally connected to the stem opposite the ball.

4. The pressure relief ball valve as claimed in claim 1 comprises:

a seat being mounted within the valve chamber; and

the ball being nested in the seat.

5. The pressure relief ball valve as claimed in claim 1, wherein the ball is a floating ball.

6. The pressure relief ball valve as claimed in claim 1, wherein the ball is a trunnion ball.

7. The pressure relief ball valve as claimed in claim 1, wherein the fluid conduit is a full port.

8. The pressure relief ball valve as claimed in claim 1, wherein the fluid conduit is a reduced port.

9. The pressure relief ball valve as claimed in claim 1, wherein the fluid conduit is a V port.

10. A pressure relief ball valve comprises:

a valve body comprising an inlet, an outlet, and a valve chamber;

the valve chamber being positioned in between the inlet and the outlet;

a seat being mounted within the valve chamber;

the ball being rotatably nested in the seat;

a fluid conduit traversing through the ball;

a drain hole traversing into the ball;

the drain hole being angularly offset from the fluid conduit;

the drain hole being in fluid communication with the fluid conduit;

a stem traversing through the valve body;

the stem being engaged with the ball;

a lever handle being terminally connected to the stem opposite the ball;

the ball being configurable between an open position and a closed position through the lever handle;

the drain hole being offset from the outlet when the ball is in the open position;

the fluid conduit being in fluid communication with the inlet and the outlet when the ball is in the open position;

the drain hole being positioned adjacent to the outlet when the ball is in the closed position;

the fluid conduit being disjointed from the inlet and the outlet when the ball is in the closed position;

11. The pressure relief ball valve as claimed in claim 10 comprises:

the drain hole being perpendicular to the fluid conduit;

12. The pressure relief ball valve as claimed in claim 10, wherein the ball is a floating ball.

13. The pressure relief ball valve as claimed in claim 10, wherein the ball is a trunnion ball.

14. The pressure relief ball valve as claimed in claim 10, wherein the fluid conduit is a full port.

15. The pressure relief ball valve as claimed in claim 10, wherein the fluid conduit is a reduced port.

16. The pressure relief ball valve as claimed in claim 10, wherein the fluid conduit is a V port.
