Detailed Description

It should be noted that the following detailed description is exemplary and is intended to provide further explanation of the invention. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

It is noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of example embodiments in accordance with the invention. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, and it should be understood that when the terms "comprises" and/or "comprising" are used in this specification, they specify the presence of stated features, steps, operations, devices, components, and/or combinations thereof, unless the context clearly indicates otherwise.

As described in the background of the invention, at present, fire hydrants are frequently opened in daily fire hydrant inspection and drill processes, and the conditions of untight closing and the like are caused by aging, abrasion and the like of a sealing ring, so that time is required for thorough disposal, and a large amount of fire fighting water is wasted due to non-disposal. Therefore, the utility model provides a fire hydrant temporary plugging tool, it is right with the detailed description now to combine the figure the utility model discloses further explain.

Referring to fig. 1, the example of a fire hydrant temporary plugging tool designed by the utility model includes: the fire-fighting water quick connector comprises a fire-fighting water quick connector 1, a communicating pipe 2, a pressure detection device 3, a pressure relief device 4 and a valve 5; one end of the fire water quick connector 1 is connected with the communicating pipe 2, the other end of the communicating pipe 2 is connected with the valve 5, and the pressure detection device 3 and the pressure relief device 4 are both arranged on the communicating pipe 2.

It should be understood that the use of the fire water quick connector 1 to facilitate connection with a hydrant outlet does not mean that other connectors cannot be used. When in use, the waterproof quick connector 1 is arranged at the outlet interface of the fire hydrant, and then the valve is closed to stop the leakage of the fire hydrant; then the leak source is maintained, the leak pressure can be observed through the pressure detection device 3 on the communicating pipe 2 at any time in the maintenance process, after the leak source maintenance is completed, the pressure in the leak stopping tool is firstly reduced to a low level or zero through the pressure relief device 4, and then the leak stopping tool is disassembled, so that the accident caused by the disassembly under pressure is prevented.

Further, in some implementations, the valve 5 is a constant diameter ball valve, and a valve handle 6 is arranged on the valve 5, so that the constant diameter ball valve is closed through the valve handle 6, and the problem of water leakage of the fire hydrant is quickly solved.

In other implementations, the pressure detection device 3 is a pressure gauge, and a conventional pressure gauge is an instrument which uses an elastic element as a sensitive element and is used for measuring and indicating the pressure higher than the ambient pressure, and comprises an overflow hole, a pointer, a glass panel and other parts; which can conveniently display the leakage pressure and changes in real time.

Further, in some implementations, the pressure relief device 4 may be a safety valve, which is closed during the repair of the leaking stoppage and leaking point, and the pressure is released to a low level or zero by manually opening the safety valve after the repair is completed, and then the whole leaking stoppage tool is disassembled.

In addition, in some implementations, the communicating pipe 2 is a metal pipe, such as a steel pipe plated with a corrosion-resistant plating layer (galvanized layer), which can ensure good pressure resistance, and is convenient for meeting the working conditions faced during plugging, and can also maintain good corrosion resistance, and increase the service life of the plugging tool, because the communicating pipe 2 is further provided with the pressure detection device 3 and the pressure relief device 4, once the communicating pipe 2 is connected, the pressure detection device 3 and the pressure relief device 4 need to be detached and installed on a new communicating pipe, therefore, the communicating pipe 2 made of the above materials can reduce the replacement frequency of the communicating pipe as much as possible, and the detachment and installation frequency of the detection device 3 and the pressure relief device 4 can also be reduced.

Further, in some implementations, the connection between the fire water quick connector 1 and the communication pipe 2, and the connection between the communication pipe 2 and the valve 5 are detachable, such as common threaded connection, so as to facilitate subsequent maintenance and replacement of components.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art.
