Description

Pressure-adjustable ground fire hydrant Technical Field The utility model relates to the technical field of fire hydrants, in particular to a pressure-adjustable ground fire hydrant. Background The pressure-adjustable fire hydrant is a fire-fighting facility with special functions. It is equipped with a pressure regulating device based on the conventional fire hydrant structure. In a fire rescue scene, different fire scales, fire-fighting equipment and fire-extinguishing positions have different requirements on water pressure, and the fire hydrant can flexibly adjust the pressure of output water according to actual requirements. The Chinese patent with publication number CN222314131U discloses a fire hydrant with adjustable pressure, which is characterized in that a bolt body, a connecting rod, a sealing element and an adjusting element are arranged, the abutting position of the connecting rod and an arc-shaped sliding guide surface is changed by rotating the rotating element, and the elastic force of the connecting rod and a first spring is opposite to the connecting rod, so that the relative position of the sealing element in the bolt body can be controlled to control the flow of fluid between a second flow hole and the first flow hole, and the fluid pressure of an outflow pipe is adjusted.
