Abstract
A check valve includes a casing member, a tear-drop shaped ball member installed in the casing member, a latching member which is formed at an inner wall of the casing member and an airtight valve which is formed at an inner wall of the casing member. When forward flux occurs, the ball member is fixed at the latching members absolutely to circulate the forward flux stably. When backward flux occurs, the ball member is latched at the airtight member to close the casing member and thus, to suppress the backward flux.
Claims13
A check valve comprising;
- a casing member,
- a ball member installed in said casing member,
- a latching member which is formed at an inner wall of said casing member and generates forward flux while said ball member is latched, and
- an airtight valve which is formed at an inner wall of said casing member and closes said casing member to suppress backward flux while said ball member is latched,
- wherein said ball member is made in tear-drop shape.
An auxiliary circulating device comprising an auxiliary circulating device main body and a check valve joined with said main body,
- said check valve comprising;
- a casing member,
- a ball member installed in said casing member,
- a latching member which is formed at an inner wall of said casing member and generates forward flux while said ball member is latched, and
- an airtight valve which is formed at an inner wall of said casing member and closes said casing member to suppress backward flux while said ball member is latched,
- wherein said ball member is made in tear-drop shape.
A method for driving an auxiliary circulating device, comprising the steps of:
- joining a check valve including a casing member and a ball member installed in said casing member with an auxiliary circulating device main body,
- latching said ball member at a latching member formed at an inner wall of said casing member to generate forward flux, and
- latching said ball member at an airtight member formed at an inner wall of said casing member, to close said casing member and thus, suppress backward flux.
