Fire hydrant
The invention discloses a fire hydrant. The fire hydrant comprises a hydrant body, a lower valve seat connected with the hydrant body, an operating rod arranged in the hydrant body and a valve elementarranged in the lower valve seat, wherein the operating rod is connected with the valve element, the valve element is provided with a first water feeding channel penetrating through the valve element, the lower valve seat is provided with a second water feeding channel penetrating through the lower valve seat and a drainage channel penetrating through the lower valve seat, the drainage channel communicates with the outside, the valve element synchronously rotates relative to the lower valve seat along with the operating rod, when the first water feeding channel corresponds to the second waterfeeding channel, the fire hydrant is in an open state for water feeding, and when the first water feeding channel corresponds to the drainage channel, the fire hydrant is in a closed state for drainage. According to the fire hydrant, water feeding and water draining are achieved through relative rotation of the valve element and the lower valve seat, water draining can be conducted when the firstwater feeding channel corresponds to the drainage channel, no accumulated water exists in the hydrant body of the fire hydrant, and the fire hydrant is protected against frost cracking.
本发明公开一种消防栓，其包括栓体、与所述栓体连接的下阀座、设于所述栓体内的操纵杆、以及设于所述下阀座内的阀芯，所述操纵杆与所述阀芯连接，所述阀芯设有贯穿其上的第一通水通道，所述下阀座设有贯穿其上的第二通水通道、和贯穿其上的排水通道，所述排水通道与外界连通；所述阀芯随所述操纵杆相对于所述下阀座同步转动，所述第一通水通道与所述第二通水通道对应时，所述消防栓为打开状态，进行通水；所述第一通水通道与所述排水通道对应时，所述消防栓为关闭状态，进行排水。本发明提供的消防栓通过阀芯和下阀座的相对转动实现通水与排水，第一通水通道与排水通道对应就可进行排水，使得消防栓的栓体内无积水，保护消防栓不被冻裂。
