The present invention provides a fire hydrant angle valve sleeve which improves a conventional method of tack-welding a connection portion of a hydrant housing of a fire hydrant and a fire pipe, supports the pipe, prevents an inflow of a foreign substance, shortens a process, and prevents damage to the hydrant housing. According to the present invention, the fire hydrant angle valve sleeve is divided into a pipe unit disposed on one side of a fire hydrant, and a fire hydrant unit disposed on the other side of the fire hydrant. The pipe unit comprises: an outer wall plate tightly adhering to a wall surface of the fire hydrant; and a mounting pipe formed on the outer wall plate. The fire hydrant unit comprises: an inner wall plate tightly adhering to the wall surface of the fire hydrant; and a pipe support pipe formed on the inner wall plate. A process of forming a connection portion of the pipe and the hire hydrant is simplified when compared to a conventional method of tack welding, and the connection portion is firmly and stably fixed by the pipe unit and a hydrant mounting unit to completely prevent problems caused by the conventional method such as pipe damage, a foreign substance entering into the fire hydrant, etc. |
