Problems solved by technology

[0003] In reality, the underground part of the outdoor fire hydrant is directly connected to the water inlet pipe network, the bottom is not protected, and the stability is poor, and the valve stem of the above-ground part of the fire hydrant is not limited. When opening the fire hydrant in an emergency, It is easy to cause the valve stem to slip out due to excessive force, causing damage to the valve disc at the lower part of the valve stem

Embodiment

[0026] refer to figure 1 and Figure 4 As shown, a light fire hydrant with locking function and high stability includes an installation base 10, a water inlet pipe 20 and a bolt body 30, and a connecting pipe 32 is arranged inside the bolt body 30, and the lower end of the connecting pipe 32 A rubberized valve disc 33 is connected, and the rubberized valve disc 33 is located in the limiting chamber 31 of the plug body 30. The limiting chamber 31 cooperates with the rubberized valve disc 33 to form a closed chamber, which cuts off the upward flow of the water body. Circulation, the lower part of the limit chamber 31 is provided with an expansion chamber 21, when the connecting pipe 32 drives the rubber-covered valve disc 33 to move down into the expansion chamber 21, the plug body 30 is opened, and the water body begins to circulate upward; the water inlet pipe 20 is curved Arc-shaped structure, the water inlet end of the water inlet pipe 20 is provided with a flange 22, the f...

Abstract

The light fire hydrant with the locking function and the high stability comprises a mounting base, a water inlet pipe and a hydrant body, a connecting pipe is arranged in the hydrant body, the lower end of the connecting pipe is connected with a rubber-coated valve clack, the upper end of the connecting pipe is fixedly connected with a lead screw, and a limiting block is arranged between the lead screw and a rotating part. A threaded sleeve is arranged on the lower side of the limiting block, arranged on the lead screw in a sleeving mode and fixed to the connecting frame. A fixing groove matched with the outer surface of the water inlet pipe is formed in the mounting base, and the water inlet pipe is embedded in the fixing groove and fixed to the fixing groove. By arranging the limiting block, the lead screw is only limited to move up and down between the dustproof cover and the threaded sleeve, the purpose of opening and closing the valve body is achieved, the situation that the lead screw is disengaged and damaged due to improper use of external force is prevented, the function of protecting the valve body is achieved, and due to the fact that the moving position of the rubber-coated valve clack is limited, abrasion of the rubber-coated valve clack is reduced, and the service life of the rubber-coated valve clack is prolonged. And the service life of the light fire hydrant is prolonged.

Description

technical field [0001] The invention relates to the technical field of outdoor fire hydrants, in particular to a light fire hydrant with locking function and high stability and a usage method. Background technique [0002] The fire hydrant is a water supply facility installed on the fire water supply pipe network outside the building. It is mainly used for fire trucks to take water from the municipal water supply pipe network or outdoor fire water supply pipe network to put out the fire. One of the fire facilities. [0003] In reality, the underground part of the outdoor fire hydrant is directly connected to the water inlet pipe network, the bottom is not protected, and the stability is poor, and the valve stem of the above-ground part of the fire hydrant is not limited. When opening the fire hydrant in an emergency, It is easy to cause the valve stem to slip out due to excessive force, causing damage to the valve disc at the lower part of the valve stem. [0004] For this...
