Description

Technical Field

[0001] The utility model relates to the technical field of fire hydrants, in particular to a fire hydrant with a flow regulation function. Background Technique

[0002] An indoor fire hydrant is an interface with a valve for supplying water from the indoor pipe network to the fire site. It is a fixed fire-fighting facility indoors for factories, warehouses, high-rise buildings, public buildings, ships, etc. It is mainly used for fire trucks to draw water from the municipal water supply pipe network or the outdoor fire water supply pipe network to implement fire extinguishing, and can also be directly connected to a water hose and a water gun to discharge water for fire extinguishing. It is one of the important fire-fighting facilities for extinguishing fires.

[0003] A Chinese patent discloses an outdoor fire hydrant and a fire hydrant monitoring system, with the publication number CN114658071A, including a fire hydrant body and a sliding plate. The fire hydrant body is provided with a water inlet and several water outlets. A valve rod is arranged in the fire hydrant body and the valve rod penetrates through the fire hydrant body. A valve flap is arranged on the valve rod. A valve seat is arranged in the fire hydrant body. The valve flap is sealed on the valve seat. The fire hydrant body is also provided with a monitoring system for monitoring the fire hydrant. A first channel is opened on the valve seat. The sliding plate is slidably arranged in the first channel. The sliding plate separates the valve flap from the water inlet of the valve seat to separate the valve flap from the water. A drainage device for draining the water flow in the fire hydrant body completely is arranged between the valve seat and the sliding plate. A sliding device for pushing the sliding plate to open and close the valve seat to let water through is arranged in the fire hydrant body.

[0004] However, it still has the following disadvantages: The fire hydrant is set above the ground, which is convenient for fire trucks to draw water. However, after the fire hydrant is slightly impacted by a vehicle, it may be deformed, resulting in water leakage and wasting resources. For this reason, we have proposed a fire hydrant with a flow regulation function to solve this problem. Content of the Utility Model

The front outer surface of the elastic clamping plate 217 extends into the interior of the clamping groove and is clamped with the inner wall of the clamping groove;

[0027] The rear outer surface of the first rotating shaft 212 passes through the front surface of the fire hydrant main body 1 through a bearing and extends to the rear of the fire hydrant main body 1. The front and rear end faces of the first rotating shaft 212 are fixedly connected to the inner wall of the bottom shell 215. The top end of the spring 214 is fixedly connected to the outer surface of the fire hydrant main body 1.
