Embodiment 1
[0031] Such as figure 1 As shown, a pressure drop flow test system for pipeline flame arrester testing, including an air supply device 1, a pressure control device, a pressure drop flow test device and a controller, an air supply device 1, a pressure control device and a pressure drop flow test The devices are connected sequentially. The air supply device 1 can be an air compressor or a fan, and is mainly used to directly provide air for the system, cancel the pressure storage space, and reduce potential safety hazards; the controller is a computer 9,
[0032] The pressure control device includes an electronic pressure controller 2 , a pressure transmitter 3 , a flow meter 4 , an integrator 5 , and a thermocouple 6 . The pressure drop flow test device includes pipeline flame arrester 7 and electronic pressure gauge 8, air supply device 1, electronic pressure controller 2, pressure transmitter 3, flow meter 4, and pipeline flame arrester 7 are sequentially connected through pi...
Embodiment 2
[0037] This embodiment provides a method for testing a pressure drop flow test system for a pipeline flame arrester, which is performed using the pressure drop flow test system described in Embodiment 1, including the following steps:
[0038] (1) Open the air supply device 1 to deliver air with pressure in the pipeline;
[0039] (2) Regulate the electronic pressure controller 2 through the computer 9, adjust the gas pressure through the electronic pressure controller 2, and provide air with a stable pressure for the follow-up pipeline, that is, the pressure of the connected pipeline after the electronic pressure controller 2 can be controlled by the electronic pressure controller 2 control, regulated by computer 9;
[0040] (3) The data measured by the air in the pipeline through the pressure transmitter 3, the flowmeter 4, and the thermocouple 6 are converted at the calculator 5, and finally the flow result under the standard condition is fed back to the computer 9, which ca...
Embodiment 3
[0045] Take the pressure drop flow test of a pipeline flame arrester with a nominal diameter of DN50 as an example:
