Tail end water testing device and method

Abstract

The invention discloses a tail end water testing device and method. The tail end water testing device comprises a box and further comprises a pressure gauge and a water testing pipe arranged at the back end of the box. The water testing pipe is fixedly connected with the box through a support. The pressure gauge is arranged at the upper end of the box. The pressure gauge is fixedly connected withthe box through a pressure gauge valve. The tail end water testing method comprises the steps that a, the tail end water testing device is installed on a tail end pipeline of a fire fighting water pipe network through a rapid connector; b, the tail end water testing device is opened, and pressure generated by water flow is obtained; c, a manual-automatic switch is pressed down, and a manual-automatic conversion circuit switches the automatic state into the manual state; d, after an infrared sensor senses a human body, a display screen is lightened and displays the information detected by the tail end water testing device. According to the tail end water testing device and method, it is avoided that the display screen is light constantly, so that electricity can be greatly saved; free switching between manual operation and automatic operation is achieved; the communication mode has the anti-interference capacity; the water testing pipe is easy, convenient and rapid to assemble and disassemble; and a water testing spray nozzle can be selected according to needs.

Description

technical field [0001] The invention relates to a device and a method, in particular to a terminal water testing device and a method. Background technique [0002] The automatic sprinkler system is currently the most effective self-rescue fire extinguishing method recognized in the world. The system has the advantages of safety, reliability, economy and practicality, and high success rate of fire extinguishing. The automatic sprinkler system is composed of sprinkler head, water flow alarm device, wet alarm valve group, control valve, terminal water test device, pipeline and water supply facilities, etc. The pipes of the system are filled with pressurized water. Once a fire occurs, the sprinkler will spray water immediately after the action. Among them, the terminal water test device is used for the regular inspection of the automatic sprinkler system. Through this device, the operation status of the entire system can be detected. The terminal water test device is installed ...

AI Technical Summary

Problems solved by technology

[0003] The terminal water testing device in the prior art has no human body sensing function, and the interface is always on, which is an unnecessary light source point when not in use, which affects the appearance and wastes energy; the manual-automatic switching device has a neutral position, and the manual-automatic status display is not clear; anti-interference Poor ability; the water test pipe joint is fixed with thread, and it is difficult to install; the water test nozzle is difficult to disassemble and cannot be replaced, etc.
