The upper bolt body 2 is internally provided with a spinning rod 11, the upper side of the upper plate body 31 is provided with a bearing block 34, the bearing block 34 is downwards provided with a hemispherical groove 341, the upper end and the lower end of the spinning rod 11 are provided with hemispherical ends 111, the spinning rod 11 is placed in the hemispherical groove 341 of the bearing block 34 through the hemispherical ends 111, the hemispherical groove 341 is internally coated with a polytetrafluoroethylene coating, the hemispherical ends 111 are coated with the polytetrafluoroethylene coating, the lower end of the spinning rod 11 props against the sealing element 3, and the sealing element 3 is pressed downwards to open the water inlet 22 through the descending of the spinning rod 11.
The spinning rod 11, the support column 32, the water inlet 22, each first annular baffle 213 and each second annular baffle 333 are coaxially arranged.
The working principle of the anti-collision outdoor ground fire hydrant is as follows:
in normal use: the fire hydrant is opened, the rotary compression rod 11 descends, the hemispherical end 111 at the lower end of the rotary compression rod 11 downwards extrudes the pressure bearing block 34, the sealing element 3 is further moved downwards by overcoming the elasticity of the spring 4, the valve clack 33 descends to open the water inlet 22, fire water is sprayed upwards through the water inlet 22, and the water through holes 311 formed in the upper plate body 31 can enable the fire water to better pass upwards; after the use, the spinning rod 11 rotates and rises, the sealing element 3 rises upwards under the action of the spring 4, meanwhile, the guide rod 211 is matched with the guide hole 312 to ensure that the sealing element 3 rises vertically, namely, the valve clack 33 can be accurately embedded into the stepped groove 23, and the sealing rubber layer 331 has a better sealing effect. Because the valve clack 33 is closed from bottom to top, the pressure of fire water below the underground bolt body 2 has upward thrust on the valve clack 33, and the sealing effect of the valve clack 33 on the water inlet 22 is ensured; when the valve clack 33 seals the water inlet 22, the first annular baffles 213 and the second annular baffles 333 are alternately embedded to form a labyrinth seal structure, the labyrinth seal structure surrounds the periphery of the valve clack 33, and the labyrinth seal structure can greatly reduce the pressure of water flow, so that fire water with high pressure is prevented from leaking from the edge of the valve clack 33; when no water exists in the fire hydrant or the water pressure is low, the sealing element 3 is ensured to be fixed due to the existence of the spring 4, and the valve clack 33 is kept in a state of closing the water inlet. The spinning rod 11 descends or ascends in a rotating mode, the hemispherical end 111 at the lower end of the spinning rod 11 is matched with the hemispherical groove 341 of the bearing block 34, stability of the spinning rod 11 in rotation is achieved, meanwhile, the polytetrafluoroethylene coating coated on the hemispherical end 111 and the hemispherical groove 341 has a self-lubricating effect, and friction force between the hemispherical end 111 and the hemispherical groove 341 is reduced.
When the impact occurs, the upper-ground bolt body 1 which is impacted is separated from the lower-ground bolt body 2, the spinning rod 11 is arranged in the upper-ground bolt body 1, and the spinning rod 11 is not connected with the sealing member 3 along with the separation of the upper-ground bolt body 1, and only the hemispherical end 111 and the hemispherical groove 341 of the pressure bearing block 34 are contacted with each other, so that the separation of the spinning rod 11 does not influence the sealing member 3. The upward elastic force of the spring 4 to the upper plate body 31 and the upward pressure of fire water to the valve clack 33 are all the time, the valve clack 33 of the sealing element 3 is always in the position for sealing the water inlet 22, even if the lower bolt body 2 deforms when collision occurs, due to the arrangement of the labyrinth sealing structure formed by the first annular baffle plate 213 and the second annular baffle plate 333, the water pressure entering the water inlet 22 is very small, and the sealing effect of the valve clack 33 to the water inlet 22 is further ensured.
The above description is only an embodiment of the present invention, but the design concept of the present invention is not limited thereto, and any insubstantial modifications made by using the design concept should fall within the scope of infringing the present invention.
