Description

Technical Field

[0001] The utility model belongs to the technical field of fire-fighting joints, in particular to a water connecting valve for fire-fighting. Background Art

[0002] Fire hydrants, generally called fire hydrants, are a type of fixed fire-fighting facility, whose main function is to control combustibles, isolate combustion-supporting materials, and eliminate ignition sources. They are generally divided into ground fire hydrants and underground fire hydrants. The most common fire hydrants are generally installed on the ground. Fire hydrants are mainly used for fire trucks to take water from the municipal water supply network or the outdoor fire water supply network to extinguish fires. They can also be directly connected to water hoses and water guns to discharge water for fire extinguishing. When working, the handle needs to be rotated counterclockwise to open the valve core at the bottom of the fire hydrant, and then the water inside the fire pipe is pumped out under the action of its own water pressure, and the fire is extinguished through water hoses and other equipment. The existing fire hydrants still have the following shortcomings in actual use: first, in actual use, the existing fire hydrants require firefighters to first unscrew the screw cap of the water inlet, then tighten the water hose joint of the fire hose, screw the fire hose into the fire hydrant, and then open the valve of the fire hydrant to discharge water for fire extinguishing. This process is relatively complicated and takes a certain amount of time. In an emergency, every minute and every second represents life and economic loss. This setting is not conducive to carrying out fire extinguishing operations in the first place, and it consumes a certain amount of physical strength of the operator; secondly, in an emergency, the operator is very likely to fail to screw the water hose joint into place when fighting the fire, and the water hose joint may become loose when spraying water for fire fighting, which has a serious adverse effect on the subsequent fire fighting work.

[0019] In one embodiment of the present invention, Figures 1-2As shown, a fire-fighting water inlet valve is provided, including a joint body 10 and a limiting ring 20. The joint body 10 also includes a water groove 11 and a mounting groove 12. The center of the water groove 11 coincides with the center of the joint body 10, and the water groove 11 passes through the joint body 10 in the vertical direction. The mounting groove 12 is annular, and the mounting groove 12 is arranged on the outside of the water groove 11 and surrounds the water groove 11. The limiting ring 20 is arranged in the mounting groove 12, and the outer ring of the limiting ring 20 is connected to the inner side wall of the joint body 10, and an installation cavity 13 is also provided between the limiting ring 20 and the bottom of the joint body 10. The limiting ring 20 is also provided with a plurality of through grooves 21, each of which passes through the limiting ring 20 in the vertical direction, and each of which is communicated with the inside of the limiting ring 20. In this embodiment, a plurality of protrusions corresponding to the through groove 21 are extended from the side of the joint of the fire hose. When the fire hose is connected to the fire-fighting water inlet valve provided by the utility model, it is only necessary to put the fire hose into the installation groove 12 and align the protrusions with the through groove 21. At this time, the fire hose is connected to the water groove 11. Then the protrusion passes through the through groove 21 into the installation cavity 13 and then the fire hose is rotated. The fire hose can be clamped in the installation cavity 13. The installation method is convenient, fast and firm. It can greatly speed up the rescue speed when dealing with emergencies such as fires, and is convenient for firefighters to quickly carry out firefighting work.

[0020] Furthermore, a sliding ring 30 and an elastic member 31 are also provided in the installation cavity 13. The sliding ring 30 is slidably arranged in the installation cavity 13 in the vertical direction. One end of the elastic member 31 abuts against the bottom of the sliding ring 30, and the other end abuts against the bottom of the joint body 10. In this embodiment, when the fire hose passes through the through groove 21, the sliding ring 30 is pressed, and the sliding ring 30 moves downward in the vertical direction. Then, the fire hose is rotated and the fire hose is loosened. The sliding ring 30 is reset under the action of the elastic member 31, and the fire hose is driven to abut against the limit ring 20, thereby fixing the fire hose to prevent the fire hose and the joint body 10 from falling off during the water flow process, which affects the rescue progress.

[0021] Further, the outer side of the sliding ring 30 is parallel to the outer side of the mounting groove 12, and the inner side of the sliding ring 30 is parallel to the inner side of the mounting groove 12.

[0022] Furthermore, two sealing rings are included, both of which are arranged at the bottom of the sliding ring 30, and the two sealing rings are respectively located at the outer ring of the sliding ring 30 and the inner ring of the sliding ring 30. In this embodiment, the sealing ring seals the installation cavity 13 to prevent moisture from entering the installation cavity 13, thereby corroding the elastic member 31 in the installation cavity 13, and causing the elastic member 31 to fail.

[0023] Furthermore, the limiting ring 20 is provided with a plurality of limiting grooves 22, each of which is arranged at the bottom of the limiting ring 20, and each of which extends upward in the vertical direction from the bottom of the limiting ring 20. In this embodiment, when the fire connector is clamped in the mounting groove 12, the protrusion on the fire hose moves into the limiting groove 22, and the sliding ring 30 abuts against the protrusion of the fire hose, so that the protrusion of the fire hose is located in the limiting groove 22, thereby preventing the fire hose from loosening due to water pressure, thereby disconnecting the fire hose and the connector body 10.

[0024] Furthermore, a protective sleeve is included, the outer side of the joint body 10 is provided with an external thread, the inner side of the protective sleeve is provided with an internal thread matching the external thread, the protective sleeve is detachably connected to the joint body 10, and the protective sleeve is sleeved on the joint body 10. In this embodiment, when not in use, the protective sleeve plays a protective role to prevent foreign matter from falling from the water groove 11 and causing the water groove 11 to be blocked.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
