Abstract
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.
Claims2
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.
