Embodiment Construction

[0008] A non-destructive technique for a guide rod of an above-ground fire hydrant after collision, mainly comprising the following steps: A. dividing the guide rod in the hydrant body into two sections; B. connecting the two through a saw-tooth clutch. The structure of the ground fire hydrant manufactured by the present invention will be described in further detail below in conjunction with the accompanying drawings. Referring to the accompanying drawings, an above-ground fire hydrant with no damage to the guide rod after collision is mainly composed of a bolt body 1, a valve body 7 and a guide rod. The bolt body 1 and the valve body 7 are connected by safety bolts 3. Bar is divided into two sections 8,9, and is connected by saw-tooth clutch 2, is provided with valve ring 4 under saw-tooth clutch 2, is covered with spring 5 on guide rod 9, and the bottom of guide rod 9 is provided with valve plug 6.

Abstract

The collision damage preventing technology for the guide bar in pillar hydrant includes the following main steps: separating the guide bar inside the hydrant body into two sections and connecting these two sections through one sawtooth clutch. In case of collision to the pillar hydrant, the safety bolt is broken to separate the hydrant body from the valve body, the guide bar is divided into two sections, the valve ring acts as the stabilizing basin after losing the pressure of the hydrant body, and the valve plug under the action of the spring is closed automatically to save water.

Description

technical field [0001] The invention relates to the technical field of fire-fighting equipment manufacturing, in particular to a manufacturing process of an above-ground fire hydrant with an anti-collision structure. Background technique [0002] At present, the known anti-collision type fire hydrant on the ground, after being knocked down, the guide rod is damaged, and the hydrant will not automatically close. When the hydrant is knocked down when the hydrant is opened, the water will rush out, which not only wastes precious water resources, but also brings unsafety to the environment. factor. Contents of the invention [0003] The purpose of the present invention is to provide a technology that can effectively overcome the above-mentioned defects, the guide rod will not be damaged when knocked down, and the guide rod will not be damaged after the collision of the above-ground fire hydrant that will automatically cut off the water source. [0004] In order to achieve the...
