Problems solved by technology

[0002] The outdoor fire hydrant with split flange is used outdoors, and there is no protective measure for the fire hydrant in the prior art. Therefore, when the fire hydrant is impacted by external forces, such as vehicles, falling rocks, and building collapses, the fire hydrant will directly break. Causes the water flow to be sprayed directly from the fire hydrant, which not only wastes the water source, but also reduces the water volume and pressure in the fire pipe network, especially when water is needed in other places, the fire extinguishing equipment cannot be used due to the loss of water volume and pressure Effective fire extinguishing, easy to cause greater losses

Embodiment Construction

[0018] In order to better understand the present invention, the implementation manner of the present invention will be explained in detail below in conjunction with the accompanying drawings.

[0019] Such as Figure 1 to Figure 5 As shown, an outdoor fire hydrant with a split flange includes a bolt shell 1 and a lower valve body 8, a bolt shell flange 4 is provided at the bottom of the bolt shell, and a connecting pipe at the bottom of the bolt shell flange 4 is provided with There is an anti-collision flange 5, the upper part of the lower valve body 8 is connected to the lower end of the connecting pipe 11, the upper end of the connecting pipe 11 is connected to the second flange 9, the anti-collision flange 5 is connected to the second flange 9, and the second flange 9 is located at the position where the fire hydrant is installed close to the upper part of the ground 10. The anti-collision flange 5 includes two thin semi-cylindrical ring structures 51, 52 with axial holes ...

Abstract

The invention discloses an outdoor fire hydrant with a split flange, wherein the outdoor fire hydrant comprises a hydrant shell and a lower valve body, wherein a hydrant shell flange is arranged on the lower part of the hydrant shell; an anti-collision flange is arranged on a connecting pipe on the lower part of the hydrant shell flange; the upper part of the lower valve body is connected to the lower end of the connecting pipe; the upper end of the connecting pipe is connected to a flange II; the anti-collision flange is connected to the flange II; the flange II is arranged close to the upper part of ground where the fire hydrant is arranged; the anti-collision flange comprises two semicircular column ring structures which are formed with axial holes in the middles; connecting holes are formed in the semicircular column rings; an integral column ring is formed by the two semicircular column ring structures; interface covers which are relatively small in diameter are symmetrically arranged on two sides of the upper part of the hydrant shell; and an interface covers II which are relatively large in diameter are arranged on the lower sides of the interface covers. By virtue of the split flange, the fire hydrant disclosed by the invention, since flange joint becomes broken firstly in the case of collision, is prevented from water leakage and pressure relief, so as to avoid other unsafe factors and subsequent losses in the case of leakage in some fire hydrant.

Description

technical field [0001] The invention relates to the technical field of outdoor fire fighting equipment, in particular to an outdoor fire hydrant with a split flange. Background technique [0002] The outdoor fire hydrant with split flange is used in the open air, and there is no protective measure for the fire hydrant in the prior art. Therefore, when the fire hydrant is impacted by external forces, such as vehicles, falling rocks, and building collapses, the fire hydrant will directly break. It causes the water flow to be sprayed directly from the fire hydrant, which not only wastes the water source, but also reduces the water volume and pressure in the fire pipe network, especially when water is needed in other places, the loss of water volume and pressure makes the fire extinguishing equipment unable to Effective fire extinguishing is likely to cause greater losses. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned ...
