Problems solved by technology

[0002] The existing flame arrester pressure drop flow system cannot adjust the value of the pressure drop flow, and can only measure the pressure immediately after the pressure is released from a larger pressure storage space through the pipeline flame arrester
There are many inconveniences: 1. The pressure cannot be controlled to reach the maximum value you want to choose; 2. The pressure cannot be adjusted, and the pressure can only be read quickly while the pressure is falling, and the error is large; 3. The pressure storage space is relatively demanding. High, because the larger the diameter of the flame arrester, the larger the pressure drop required to measure, the higher the pressure requirement of the pressure storage space, this will easily cause safety hazards; 4. Each position needs to be equipped with fixed personnel to read data, The process is complex and prone to errors

Abstract

The invention discloses a pressure drop flow testing system and method for testing a pipeline flame arrester, and belongs to the technical field of flame arrester performance testing; the pressure drop flow testing system comprises an air supply device, a pressure control device, a pressure drop flow testing device and a controller, wherein the air supply device, the pressure control device and the pressure drop flow testing device are connected in sequence. According to the invention, the pressure drop flow test in the mass standard is realized, the stability is kept at different pressure drop numerical points, the pressure drop parameters can be manually adjusted through the controller; meanwhile, the corresponding flow is read, and the measurement error is reduced.

Description

technical field [0001] The invention belongs to the technical field of flame arrester performance testing, in particular to a pressure drop flow testing system and method for pipeline flame arrester testing. Background technique [0002] The flame arrester pressure drop flow rate system in the prior art cannot adjust the value of the pressure drop flow rate, and can only measure the pressure immediately after releasing the pressure from a relatively large pressure storage space through the pipeline flame arrester. There are many inconveniences: 1. Can't control the pressure to reach the maximum value you want to choose; 2. Can't adjust the size of the pressure, you can only take a quick reading when the pressure is falling, and the error is large; 3. The pressure storage space is more demanding High, because the larger the diameter of the flame arrester, the greater the pressure drop required to measure, the higher the pressure demand of the pressure storage space, this will...
