Abstract

The invention relates to the field of fire protection facility detection, in particular to an automatic sensitivity testing device of a water flow indicator for fire protection. The automatic sensitivity testing device comprises a machine frame, a PLC control system and a hydraulic press. A water outlet pipe, a water outlet connector, a first electric adjusting electromagnetic valve, a first flow measuring pipe and a first fixing ring are sequentially connected and arranged on the machine frame, and a second fixing ring, a second flow measuring pipe, a second fixing ring stretchable pipe, a fixing pipe, a connecting pipe, an electromagnetic valve, a water inlet pipe and the hydraulic press are sequentially connected and arranged on the machine frame. A pressure sensor is arranged on the hydraulic press. Electric adjusting electromagnetic valves are installed on the two flow measuring pipes. All the electromagnetic valves, flow sensors, a pneumatic electromagnetic valve set and the pressure sensor are connected with the PLC control system. The PLC control system is connected with a camera. According to the automatic sensitivity testing device, test installation and testing process and conclusion determination are automatically completed, man-made interference is eliminated, the detection quality and efficiency are improved, and automatic detection is achieved.

Description

(1) Technical field [0001] The invention relates to the field of detection of fire-fighting facilities, in particular to an automatic test device for the sensitivity of a fire-fighting water flow indicator. (2) Background technology [0002] At present, the test and inspection of the sensitivity of the water flow indicator of the fire sprinkler system is done manually. For example, to install the water flow indicator sample, it is necessary to tighten multiple bolts evenly with a wrench. The sensitivity of the water flow indicator should be less than a certain flow rate. It should not alarm when it reaches a certain flow range, but the alarm flow must not be greater than a certain value. During the test process, due to the inevitable human interference factors that are determined by manual control operations, the detection quality and efficiency are low. (3) Contents of the invention [0003] In order to make up for the defects of the prior art, the present invention provi...
