Fire hydrant valve usable alone quickly in case of fire
View Patent ↗Disclosed herein is a fire hydrant valve (easy action valve) that is usable alone quickly in the event of fire, and more particularly, a fire hydrant valve that is usable alone quickly in the event of fire, which can be even opened from a long distance away. The fire hydrant valve includes a body formed with a first opening and a second opening, a switching unit including a rod configured to penetrate the body, and a disk provided at an end of the rod to open and close the first opening, and a first movement unit connected to the rod and a hose connected to the second opening and configured to move the rod in response to movement of the hose.
1 . A fire hydrant valve comprising:
a body formed with a first opening and a second opening;
a switching unit comprising a rod configured to penetrate the body, and a disk provided at an end of the rod to open and close the first opening;
a first movement unit connected to the rod and a hose connected to the second opening and configured to move the rod in response to movement of the hose; and
a second movement unit, which comprises a main shaft connected to the body, a moving shaft connected to the rod and placed in front of the main shaft, a plate coupled to the main shaft to rotate about the main shaft, and a guide hole formed on the plate in a direction of rotation thereof for penetration of the moving shaft through the plate,
wherein the first movement unit comprises:
a first torsion spring, which comprises a first coil surrounding the main shaft and a first arm connected to the plate by extending from an end of the first coil;
a base connected to the body;
a shaft member provided on the base;
a latching member, which comprises a body part placed on the base to rotate about the shaft member configured to penetrate the body part, a rear part extending to one side from the rear of the body part, a front part extending to one side from the front of the body part, and a latching groove formed by the body part, the rear part, and the front part;
a latching shaft provided on the plate and inserted into the latching groove; and
a second torsion spring, which comprises a second coil surrounding the shaft member, a second support arm comprising a second straight part extending backwards from one of both ends of the second coil and a second hook part connected to the base by extending downwards from a rear end of the second straight part and configured to support a rear end of the rear part, and a second fixed arm fixed to the base by extending from the other of both ends of the second coil.
2 . The fire hydrant valve according to claim 1 , wherein the first movement unit comprises:
a groove formed at a front end of the body part;
a tilting member, which comprises a vertical part penetrating the base and a connection part connected to the hose while being connected to the bottom of the vertical part;
a movable shaft provided on the base and placed forwards on the other side from the shaft member;
a transmission piece, which comprises a latching part placed at an upper portion of the base and positioned on one side from the vertical part, and an insertion part extending forwards from a front end of the latching part and bent or curved to one side to insert its end into the groove, the movable shaft penetrating the insertion part; and
a third torsion spring, which comprises a third coil surrounding the movable shaft, a third support arm comprising a third straight part extending forwards from one of both ends of the third coil and a third hook part connected to the base by extending downwards from a rear end of the third straight part and configured to support the front of one side of the insertion part, and a third fixed arm fixed to the base by extending from the other of both ends of the third coil.
