Abstract

The present invention proposes a valve assembly for controlling a fluid to flow only in a certain direction according to inclination directions. A valve body 10 of the valve assembly includes a partition 14 formed with a through hole 14a and dividing an inside into a first internal channel 18a and a second internal channel 18b, a first entrance 12a for supplying a fluid from the first internal channel to an outside or a fluid from the outside to the first internal channel, and a second entrance 12b for supplying a fluid from the second internal channel to an outside or a fluid from the outside to the second internal channel. Further, a first check roller 11a and a second check roller 11b are in close contact with or separated from the through hole by buoyancy or sedimentation according to inclination directions of the valve body, thereby controlling the fluid to flow in a certain direction. Further, the first check roller and the second check roller are prevented from being in contact with the first entrance and the second entrance by the flow of the fluid in the first internal channel and the second internal channel, and the flow of the fluid is accurately controlled by only the inclination directions.

Claims10

Dependent claims

A valve assembly comprising:

a valve body including a partition formed therein, the partition having a through hole at an upper side thereof and dividing an inside space of the valve body into a first internal channel and a second internal channel, a first entrance disposed adjacent to the first internal channel for supplying a fluid from the first internal channel to an outside or a fluid from the outside to the first internal channel, and a second entrance disposed adjacent to the second internal channel for supplying a fluid from the second internal channel to an outside or a fluid from the outside to the second internal channel;
a first check roller and a second check roller received in the first internal channel and the second internal channel, respectively, and configured to be in contact with or separated from the through hole by buoyancy in a fluid in the first internal channel and the second internal channel according to inclination directions of the valve body;
and
a restrictor configured to prevent the first check roller and the second check roller from being in contact with the first entrance and the second entrance by buoyancy or flow of the fluid in the first internal channel and the second internal channel,
wherein the restrictor comprises a pair of plate-shaped stoppers extended downward from a ceiling of the valve body between the first check roller and the first entrance and between the second check roller and the second entrance, respectively.

a first check roller and a second check roller received in the first internal channel and the second internal channel, respectively, and configured to be in contact with or separated from the through hole by sinking force in a fluid in the first internal channel and the second internal channel according to inclination directions of the valve body;
and
a restrictor configured to prevent the first check roller and the second check roller from being in contact with the first entrance and the second entrance by sinking force or flow of the fluid in the first internal channel and the second internal channel,
wherein the restrictor comprises a pair of plate-shaped stoppers extended upward from a bottom of the valve body between the first check roller and the first entrance and between the second check roller and the second entrance, respectively.
