Problems solved by technology

During the sprinkler test, the pipeline needs to go through the process of increasing pressure, maintaining pressure, reducing pressure, increasing pressure, reducing pressure, etc. It is impossible to control the water inlet valve accurately and easily only by observing the pressure gauge on the pipeline.
The nozzle fixing device of the existing sprinkler head pressure test equipment is generally a joint that can be threaded with the sprinkler head. It takes a long time to disassemble the sprinkler head and the pressure test efficiency is low.

Abstract

The invention provides a test device of a pressure test of a water spraying head. The test device is simple in testing and easy to operate, and comprises a water supplying device, a testing device and a control device. The water supplying device comprises a water tank, a water pump, a pressure stabilizing tank, a water supplying pipe and a water discharging pipe, which are successively connected. The testing device comprises a testing water pipe. At least one spray head fixing device used for fixing a water spraying head is arranged on the testing water pipe which is communicated with the pressure stabilizing tank. According to the invention, the control device compares real-time pressure information of a pressure sensor, controls rotation speed of a motor via a transducer so as to control pressure increasing speed and pressure keeping time of the water supplying pipe and controls pressure discharging pressure of the water supplying pipe via a pressure discharging assembly; automation of a test process is achieved, test is precise and simple to operate and a curve chart in which pressure changes along with time can be created after a test; via the spray head fixing devices, the water spraying head can be quickly disassembled and assembled; and via an installation rack and a water tank structure, installation density of the spray head fixing devices can be increased and water discharging is facilitated.

Description

Technical field [0001] The invention relates to the field of fire fighting equipment, and in particular to a pressure test equipment for sprinklers. Background technique [0002] The sprinkler is an important fire extinguishing component in the automatic sprinkler system that directly detects and perceives the fire. It can control the spread of fire in time and ensure the safety of life and property. The manufacturer needs to conduct a water pressure test on the sprinkler when inspecting the sprinkler. During the sprinkler test, the pipeline needs to go through the process of pressure increase, pressure maintenance, pressure reduction, pressure increase, and pressure reduction. It is impossible to accurately and easily control the inlet valve by observing the pressure gauge on the pipeline. The sprinkler fixing device of the existing sprinkler pressure test equipment is generally a joint that can be threaded with the sprinkler, it takes a long time to disassemble the sprinkler, a...
