Embodiment Construction

[0016] The structural features of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] Such as figure 1 A safety fire hydrant shown includes: an inlet elbow, a valve stem 4, a bolt valve 5 and a bolt body 1, and the bolt body 1 is divided into an upper bolt body 11 and a lower bolt body 12 above the bolt valve 5. Part, between the upper bolt body 11 and the lower bolt body 12 is connected by a circle of wearing parts 3; the valve stem connection end 41 connected with the plug valve 5 is a polygonal section, and the corresponding valve stem connection end 41 on the bolt valve 5 A groove 6 matching the connecting end 41 of the valve stem is provided at the position, and the connecting end 41 of the valve stem is plugged into the groove 6 .

[0018] When an impact occurs, the vulnerable parts are broken and damaged under the action of external force. Due to the non-rigid connection between the valve stem an...

Abstract

The invention discloses a safety fire hydrant, which comprises a water inlet elbow, a valve stem, a hydrant valve and a hydrant body, wherein the hydrant body above the hydrant valve is divided into an upper body and a lower body, which are connected with each other through a wearing ring part; the connection end of the valve stem connected with the hydrant valve has a polygonal section; a groove fitting with the connection end of the valve stem is arranged on the hydrant valve at a position corresponding to the connection end of the valve stem; and the connection end of the valve stem is inserted into the groove. The safety fire hydrant designed according to the technical scheme of the invention can effectively solve the problem of water leakage resulting from the damage of the hydrant valve caused by colliding the fire hydrant, thus reducing the influence to surrounding environment and preventing waste of water resources. The safety fire hydrant has the advantages of rapid and convenient maintenance.

Description

technical field [0001] The invention relates to a safety fire hydrant, which belongs to fire fighting equipment. Background technique [0002] With the rapid development of my country's economic construction and the continuous improvement of the country's fire safety regulations, the public's awareness of fire protection is increasing, and road fire hydrants have become one of the necessary basic fire protection facilities for cities and industrial and mining enterprises. Due to the particularity and density of fire hydrants installed on both sides of the road, it is required to be installed along the road, close to the intersection, with a distance of no more than 200 meters. The waste of precious water resources, and bring inconvenience to people's life, time-consuming maintenance replacement and water supply pipeline stop water, bring hidden danger to fire safety. Relevant data show that there are basically four types of vehicle collisions: frontal collision, side collis...
