Multifunctional ventilation valve flexibility test system and test method

Abstract

The invention belongs to a multifunctional ventilation valve flexibility test system and test method, and the system comprises a plenum chamber of the ventilation valve flexibility test system, and ischaracterized in that a pore plate flow equalizer is arranged in the cavity of the plenum chamber, the front end of the pore plate flow equalizer penetrates through a detection port arranged in the middle of the front wall of the plenum chamber, and a second gas detection control valve is arranged in the middle of a detection pipeline; the first gas access pipeline is provided with a first gas detection control valve and an MF5700 thermal flow meter; a sliding rail lock is arranged on the three-way sliding rail, and an MC-HGC1000 displacement sensor is arranged at the end of the displacementsensor support; the other end of the orifice plate flow equalizer is provided with a detection port in the middle of the rear wall of the plenum chamber, and a first flange is arranged on the detection port; and an ELM110-OAC differential pressure sensor I and an ELM112-OAC differential pressure sensor II are arranged at the upper part of the middle of the right wall of the static pressure box. Performance parameters of air valves with different calibers can be flexibly selected and detected, detection precision and effectiveness are guaranteed, and the problem that large-caliber valves are difficult to detect is solved.

Description

technical field [0001] The invention belongs to a ventilation valve testing system and a testing method, in particular to a multifunctional ventilation valve flexible testing system and a testing method. Background technique [0002] The key technical parameters of the ventilation valve (hereinafter referred to as the air valve) include the air leakage of the valve plate, the air leakage of the valve body and the deflection of the valve plate. At present, these performance tests of air valves mainly rely on testing agencies for testing, and it is difficult for large-caliber valve testing agencies to complete the testing, and the transportation of large-caliber valves to testing agencies requires high transportation costs, and there are very few companies with testing capabilities. . Due to the limitation of the measurement range and accuracy of the detection equipment, the patent No. CN110108647U authorized by the National Patent Office can detect other parameters except bl...

Problems solved by technology

At present, these performance tests of air valves mainly rely on testing agencies for testing, and it is difficult for large-caliber valve testing agencies to complete the testing, and the transportation of large-caliber valves to testing agencies requires high transportation costs, and there are very few companies with testing capabilities.

Due to the limitation of the measurement range and accuracy of the detection equipment, the patent No. CN110108647U authorized by the National Patent Office can detect other parameters except blade deflection, but the air supply system and measurement system are single, and cannot complete the detection task of a wide-caliber damper

The patent with the authorization number CN208831874U can only detect the air leakage of the valve plate of the air valve, and cannot detect the deflection of the valve plate
